Stainless steel ball valve pipe after installation, regularly carries on the maintenance and maintenance, such as the stem out often with lubricating oil. Appropriate to open and close the valve several times. Make the ball, stem, sealing surface is not easy to assimilate. We according to the structure characteristics of the stainless steel ball valve targeted maintenance and maintenance. 1. Commonly used the wafer ball valve structure features: (1) unique common wafer ball valve design between the sealing surface friction drive, prolong the service life of the valve. (2) common wafer ball valves produced by torque elastic seal. (3) clever wedge design allows for automatic sealing valve has closed more and more tightly, compensatory, zero leakage between the sealing surface. (4) small volume, light weight, light operation and ease of installation. (5) according to user requirements with pneumatic, electric devices, meet the needs of the remote control and programmed control. Material can be applied to all kinds of medium, 6 replacement parts and lining anticorrosion can be ( Lining F46, GXPP, PO, etc. ) 。 All landowners continuous structure diversification: the clamp, flange, butt welding. 2. Stainless steel ball valve ( Commonly used the wafer ball valve) The maintenance of the vast majority of ball valve seat is made of elastic material such as ptfe, sealing pair of metallic and non-metallic materials, often referred to as soft seal. In general, soft seal sealing easy to guarantee, and the machining accuracy and surface roughness on the surface of the sealing requirement is not high. Because ptfe have good self-lubrication, and sphere of friction and wear is small, and because the ball processing technology improvements, reduce roughness, thus improve the service life of the ball valve. There are two ways to reduce the resistance of piping system: one is to reduce the fluid velocity, therefore need to increase diameter and valve size, for the efficiency of pipeline system tends to produce adverse effect, especially for conveying system at low temperature ( Liquid hydrogen) Is very bad.
