When the butterfly plate is closed, the soft lining ring has a proper amount of elastic deformation to ensure zero leakage of the valve; the butterfly plate and the shaft are integrally manufactured; the PFA bearing between the shafts not only plays a guiding role in the use of the shaft, but also has good Lubrication effect; a mechanical seal is added between the butterfly plate and the valve seat ring to prevent leakage between the shafts; the soft liner butterfly valve is a kind of flexible composite material, and the rubber plus PTFE compound seat ring can generate when the valve is closed. A certain degree of elastic deformation guarantees zero leakage and excellent reciprocating performance, which greatly extends the service life of the butterfly valve. Electrically-lined Fluorine Control Valves Fluoroplastics or plastic linings are corrosion-resistant valves and piping accessories that, due to their inherent special properties, have the following characteristics in terms of product installation, maintenance, and maintenance:
1. Valve or fittings flange cover can not be disassembled, unless you are ready to connect with the pipeline, or the PTFE flange surface may affect the seal due to temperature difference, foreign objects caused by bump scratch or distortion, if the inspection needs to move the cover The board must also be reset after the inspection is completed to protect the PTFE flange surface.
2. When fluoroplastic or plastic lining valves and fittings are connected to pipelines, gaskets are generally not used alone. However, when connecting flange surfaces of dissimilar materials (metal surfaces, etc.), appropriate gaskets should be used to protect the PTFE method. Lan surface.
3. When the product is used in a system, if it leaks at a higher level, the system temperature should first be lowered to room temperature, and then the cause must be ascertained and repaired.
4. It is not allowed to do any high-temperature welding work on valves and fittings to avoid permanent damage to the lining layer.
5. The mounting flange nuts shall be screwed evenly in the order of diagonal (symmetry) and be fitted with appropriate torque:
(1) A leak has occurred on the flange sealing surface, and the nuts in the leakage position have been locked. At this time, the leakage position should be loosened by half a turn, and the same torque should be applied to the opposite side to lock again.
(2) When the above method still does not stop leaking, the PTFE flange surface should be inspected for uneven indentation and scratches, and then it can be leveled and reconnected by spinning paper or cloth.
6. Valves and fittings should be stored in a dry and ventilated room. Stacking is strictly forbidden.
7. The long-term storage of the valve should be slightly separated from the sealing state, to avoid permanent deformation of the seal long-term pressure, affect the sealing performance and service life.
8. When the valve is manually operated, it is not allowed to forcibly open and close the valve by means of other levers.
9. The directional valve is required to pay attention to the flow of the medium should be placed on the valve body as shown by the arrow, and to ensure easy operation and maintenance.
10. The repaired valve can be installed before it is tested according to relevant standards before use.
The purpose of custody and maintenance is not to damage the valve or to reduce the quality of the valve. In fact, improper storage is one of the important causes of valve damage. Keeping the valve should be well-organized, small valves placed on the shelves, large valves can be neatly arranged on the ground floor of the warehouse, can not be random mess, do not let the flange connection surface contact the ground. This is not only for beauty, but mainly to protect the valve from damage. Due to improper storage and handling, handwheel breaking, valve stem collision, loosening of the fixing nuts of the hand wheel and valve stem, etc. These unnecessary losses should be avoided. For valves that are not used for a short period of time, asbestos packing should be removed to prevent electrochemical corrosion and damage to the valve stem. Check the valves that have just entered the warehouse, such as rain or dirt in the transportation process, wipe them clean and store them again. The valve inlet and outlet should be sealed with wax paper or plastic sheet to prevent dirt from entering. Rust-protected oils should be applied to the valve surface that can rust in the atmosphere. Place the outdoor valve, must be covered with linoleum or tarpaulin like rain, dustproof items.
The purpose of maintenance is to prolong valve life and ensure opening and closing reliability. Stem thread, often friction with the stem nut, to be coated with a little yellow dry oil, molybdenum disulfide or graphite powder, play a role in lubrication, the valve does not often open and close, but also regularly turn the hand wheel to add lubricant to the stem thread To prevent biting. For outdoor valves, protect the valve stem to protect it from rain, snow and dust. If the valve is mechanically operated, add oil to the transmission on time and always keep the valve clean. Always check and maintain the integrity of the other parts of the valve. If the fixing nut of the hand wheel falls off, it must be fitted and cannot be used. Otherwise, the upper part of the valve stem will be grinded, gradually losing the reliability of cooperation, or even opening and closing. Do not rely on the valve to support other heavy objects and do not stand on the valve. The valve stem, especially the threaded part, should be wiped frequently. The lubricant that has been contaminated by dust must be replaced with new ones. Because the dust contains hard debris, it will easily wear out the threads and stem surface and affect the service life.
Filler directly related to whether the valve leakage occurs when the leakage of the key seal, if the filler fails, resulting in external leakage, the valve is equal to failure, especially the urea pipeline valve, because of its relatively high temperature and corrosion, filler, easy to aging. Enhanced maintenance can extend the life of the filler. When the valve is shipped from the factory, in order to ensure the elasticity of the filler, the static test pressure is generally not subject to leakage. After the valve is installed in the pipeline, due to factors such as temperature, extravasation may occur. In this case, tighten the nuts on both sides of the packing gland in time, as long as there is no external leakage, and then the external leakage will occur again. Tight to avoid loss of filler packing and loss of sealing performance. Some valve packings are equipped with molybdenum disulfide lubricating paste. When used for several months, the corresponding lubricating grease should be added in time. When it is found that the filler needs to be supplemented, the corresponding packing should be added in time to ensure its sealing performance.
When the valve is in the process of switching, the originally added lubricating grease will be lost continuously, and the effects of temperature, corrosion and other factors will also make the lubricating oil continue to dry up. Therefore, the transmission position of the valve should be inspected frequently, and it is found that the lack of oil should be promptly added to prevent the increase of wear due to lack of lubricant, resulting in inflexible transmission or failure of the stuck shell.
When the valve is filled with grease, the amount of grease is often ignored. After the grease gun is refueled, the operator selects the valve and grease injection method and then performs the grease injection operation. There are two situations: On the one hand, the amount of grease injected is insufficient, the grease injection is insufficient, and the sealing surface accelerates wear due to lack of lubricant. On the other hand, excessive fat injection causes waste. There is no precise calculation of the different valve seal capacities depending on the type of valve. The seal capacity can be calculated by the size and type of the valve, and the proper amount of grease can be properly injected.
When the valve is filled with grease, the pressure problem is often neglected. During the grease filling operation, the pressure of the injection grease changes regularly. Low pressure, leakage or failure of seals,
The pressure is too high, the grease injection port is blocked, the sealed grease is hardened, or the seal ring and valve ball and valve plate are locked. When the injection pressure is too low, the injected grease flows into the bottom of the valve chamber, which usually occurs in the small gate valve. The injection pressure is too high, on the one hand to check the grease injection nozzle, if the grease hole is blocked and the condition is changed, on the other hand, the grease is hardened, the cleaning fluid is used, the softened sealing grease is repeatedly softened, and the new grease is injected. . In addition, the sealing type and the sealing material also affect the injection pressure. Different sealing types have different injection pressures. In general, the hard sealing pressure is higher than the soft sealing.
When filling the valve, pay attention to the problem of the valve in the switch position. Ball valve maintenance is generally in the open state, under special circumstances choose to close the maintenance. When the valve is filled with grease, the grease injection effect is often neglected. During the grease filling operation, the pressure, grease injection volume, and switch position are all normal. However, in order to ensure the valve's grease injection effect, it is sometimes necessary to open or close the valve to check the lubrication effect and confirm that the surface of the valve ball or gate plate is evenly lubricated. When filling grease, pay attention to valve body drainage and plug pressure relief. After the pressure test of the valve, the gas and moisture in the valve chamber of the sealed chamber are boosted due to the increase of the ambient temperature. During the injection of the grease, the pressure of the sewage is discharged to facilitate the smooth progress of the grease injection. The air and moisture in the sealed cavity after the grease injection are fully replaced. Timely release of the pressure in the valve chamber also ensures the safe use of the valve. After the grease is finished, be sure to tighten the drain and drain plugs to prevent accidents. In short, we must strengthen the maintenance of daily work, pay attention to the normal use of the valve, if any suspicious problems should be resolved in a timely manner, can not be delayed.
