Abstract

The invention relates to air pressure treatment elements, in particular to a one-way throttle valve. The one-way throttle valve comprises a valve body, a throttling valve element and a one-way valve element, wherein the valve body is provided with a cavity inside, and the cavity comprises a first cavity, a second cavity and a first air flue, and a second air flue is formed in the valve body; the throttling valve element is mounted in the first cavity for adjusting the gas flow of the first air flue; the one-way valve element is mounted in the second cavity and comprises a plug screw fixedly connected to the second cavity, the plug screw is provided with a third cavity, a third air flue is formed in the wall of the third cavity, and a valve nozzle, a valve assembly, a spring and a limitingseat are successively mounted in the third cavity; and the second air flue, the first air flue, the valve nozzle and the third air flue form a communicating gas one-way channel. According to the one-way throttling valve, the one-way valve element is serially connected to the throttling valve element, so that the one-way throttling valve not only can be taken as the one-way valve or the throttlingvalve and has diverse gas source treatment modes, but also is compact in structure, easy in mounting mode and suitable for occasions relatively high in degree of integration, such as a valve island.

Description

technical field [0001] The invention relates to an air pressure processing element, in particular to a one-way throttle valve. Background technique [0002] The traditional one-way throttle valve is composed of ordinary one-way valve and ordinary throttle valve connected in parallel. When the medium can pass in a specific direction, it can throttle, and when the medium passes in the opposite direction, it can flow freely. [0003] This kind of one-way throttle valve in parallel connection cannot provide specific direction throttling, reverse non-conductive connection scheme, and the gas source processing capacity is insufficient. At the same time, the size of the parallel one-way throttle valve is large, and the installation method is usually connected with the pipe joint and then connected with other components. In some installations that require a compact structure, it cannot meet the assembly requirements, especially the current high integration requirements. Valve islan...
