1. The filler is directly related to whether the key seal of the external leakage occurs when the copper valve is switched. If the filler fails, the leakage is caused, and the valve is equal to the failure. Especially the valve of the urea pipeline is relatively high in corrosion due to its high temperature. Easy to age. Enhanced maintenance can extend the life of the packing. Spice Novelties Co.,Limited , https://www.wholesale-adult-toys.cn
2. When the copper valve is shipped from the factory, in order to ensure the elasticity of the packing, the static pressure test is generally not allowed to leak. After the valve is installed in the pipeline, due to temperature and other factors, extravasation may occur. At this time, the nut on both sides of the pressure gland of the pressure-retaining valve should be tightened in time, as long as no leakage occurs, and then extravasation occurs later. Once again, do not die tightly to avoid loss of elasticity and loss of sealing performance.
3. Some copper valve fillers are filled with molybdenum disulfide grease. When used for several months, the corresponding grease should be added in time. When the filler needs to be added, the corresponding filler should be added in time to ensure its sealing performance.
Maintenance of the transmission parts Remarks: During the switching process of the copper valve, the original added lubricating grease will be continuously lost, and the effects of temperature, corrosion and other factors will also cause the lubricating oil to dry continuously. Therefore, the transmission part of the valve should be checked frequently, and it is found that the lack of oil should be replenished in time to prevent the loss of wear due to the lack of lubricant, resulting in inflexible transmission or failure of the casing.
