Abstract

An axial flow type quick switch valve comprises a valve body and a valve element, a valve element sleeve is fixed in an inner cavity of the valve body through a key, and a flow channel is arranged between the periphery of the valve element sleeve and the inner cavity of the valve body. The valve element sleeve is provided with a cavity, a buffering cavity is formed between the rear portion of the cavity and the tail end of the valve element, and a spring is installed in the buffering cavity. The buffer cavity is communicated with external high-pressure gas through a flow channel arranged on the valve body; the front part of the valve core and the front part of the cavity of the valve core sleeve are in sealing reciprocating motion connection through a sealing ring; the front end of the valve element is in sealing contact with the valve seat. The anti-collision valve element is simple in structure, convenient to install and suitable for ultrahigh-pressure media and devices requiring quick opening, and the anti-collision problem of the valve element is effectively solved.

Description

technical field [0001] As a field of general mechanical equipment, the invention specifically relates to an axial-flow fast switching valve. Background technique [0002] In order to solve the problem that the valve can be opened or closed quickly under the condition of ultra-high pressure (>42Mpa) medium, the nominal diameter of the pipeline is DN≤40, and the valve opening time is required to be within milliseconds. This requirement is extremely demanding on the structure and performance of the valve. It is difficult for ordinary valves to meet this requirement. Therefore, a kind of axial-flow fast switch valve is designed, the valve structure is a relatively new and unique structure, and can fully meet the requirements of this special working condition. Contents of the invention [0003] The invention provides an axial-flow fast switch valve, which solves the requirement that the valve can be opened quickly in the ultra-high pressure medium of a small pipeline, and t...
