Abstract

The invention discloses an axial-flow type pneumatic control balancing stop valve which comprises a shell, wherein a valve seat assembly is arranged at one side in the shell, an outlet B is formed at one side of the valve seat assembly, a movable valve seat is arranged at the other side of the valve seat assembly, a movable valve is arranged in the movable seat assembly, a knot is arranged at one side of the movable valve, and a sealing pad is arranged at the end part of the knot. According to the design of the invention, axial-flow type design is adopted, the structure is compact, and required mounting space is small. The valve seat of existing stop valves on the market are all fixed, while the movable valve seat with a balancing hole, adopted by the stop valve disclosed by the invention, is long in life and flexible and reliable in opening and closing.

Description

technical field [0001] The invention relates to an axial-flow air-controlled balance cut-off valve. Background technique [0002] Axial-flow air-controlled balance shut-off valve is a shut-off valve controlled by a pressure air source, with axial air intake, to control the on-off of fluid in the high-pressure system, and realize the on-off control. The product is small in size, small in flow resistance, easy to install, saves installation space, and can realize remote control. It is mainly used in high-pressure fluid systems. The valve seats of the existing air-controlled balanced globe valves are all fixed, insensitive to opening and closing, occupy a large space, and are easily damaged during use. The airtightness of the existing air-controlled balance stop valve is not good, and gas leakage often occurs during use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an a...
