High temperature and high pressure check valve maintenance ten measures introduced
Lubricate with grease. Grease should be compatible with high temperature and high pressure valve metal materials, rubber parts, plastic parts and working medium. When the working medium is gas, special 221 grease, for example, can be used. Apply grease to the surface of the seal installation groove, apply grease to the rubber seal, and apply grease to the sealing surface and friction surface of the valve stem.

There are several connection methods for pipe valves of high and medium pressure ball valves
Some parts, joints and high and medium pressure valves on the gas transmission pipeline are collectively referred to as instrument high and medium pressure ball valves. The stability of the high and medium pressure ball valve directly determines the consumption and wear of the instrument, which will also be affected in chemical production. The high and medium pressure ball valve of the instrument with poor stability will cause the accuracy of the instrument to drop and the maintenance amount of the instrument to become larger. These problems are all problems that the instrument operator does not want to encounter.

Ball valve (ball valve ), opening and closing parts (ball) driven by the valve stem, and around the axis of the ball valve for rotating movement of the valve. Can also be used for fluid regulation and control, including hard seal V-shaped ball valve of its V-shaped ball core and hard alloy surfacing metal valve seat has a strong shear force, especially suitable for containing fiber, small solid particles and other media. The multi-way ball valve in the pipeline can not only flexibly control the convergence of media, diversion, and flow switching, but also can close any channel to connect the other two channels. This type of valve in the pipeline should generally be installed horizontally. Ball valve according to the driving mode is divided into: pneumatic ball valve, electric ball valve, manual ball valve.
