Straight-through valve with filtering function

Abstract

The invention discloses a straight-through valve with a filtering function. The straight-through valve comprises a straight-through valve body and a valve element, wherein the valve element is arranged in the valve body, and a cover plate for blocking the inlet end is installed on the end face of the inlet end of the valve body. A filtering barrel coaxial with the valve body is inserted into the valve body from the inlet end, and the filtering barrel is surrounded by a filter screen. The filtering barrel is located between the valve element and the inlet end of the valve body, one bottom faceof the filtering barrel is completely opened, the other bottom surface of the filtering barrel is sealed by the filter screen, and the open bottom surface of the filtering barrel is connected with thecover plate. A through hole communicating with the filtering barrel is formed in the cover plate, the through hole is coaxial with and equal to an opening in the bottom surface of the filtering barrel, and fluid sequentially passes through the through hole and the filtering barrel and then enters the valve body. The structure of a traditional straight-through valve is changed, the fluid can be purified, and an anti-blocking function is achieved.

Description

technical field [0001] The invention relates to a valve, in particular to a straight-through valve with filtering function. Background technique [0002] A valve is a control component in a fluid delivery system, with functions such as cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard custom-made valves, et...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that once the fluid flowing through the valve contains dregs, the valve will be blocked and the use of the valve will be affected. It will cause the valve to block and affect the use of the valve
