Abstract

The invention relates to an axial-flow type air control balance stop valve and belongs to the field of air control stop valves. The axial-flow type air control balance stop valve comprises a shell 1, a valve seat assembly 2, a joint head 3 and a sealing gasket 4. An air source is controlled to enter the valve from a control port 5 and push a piston 6 and a reset spring 21 on a movable valve seat 7, the movable valve seat 7 and the sealing gasket 4 are disengaged, and then the valve is opened; after the air source is controlled to stop supplying air, the movable valve seat 7 makes contact with the sealing gasket 4 again and is sealed under the action of the reset spring 21, air flow in a system is cut off, and the valve is closed. The axial-flow type air control balance stop valve is small in size, low in flow resistance, convenient to install, capable of saving installation space, mainly applicable to a high-pressure fluid system and suitable for large-range popularization.

Description

technical field [0001] The invention relates to the field of air-controlled shut-off valves, in particular to an axial-flow air-controlled balanced shut-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. [0003] The high-pressure globe valves currently on the market have the following disadvantages: [0004] 1. The high-pressure valve has a large volume, so it requires a large installation space. [0005] 2. The valve seats are all fixed, which is convenient for disassembly and maintenance, and makes the opening and closing of the globe valve sensitive and reliable. [0006] 3. The flui...
