Copper valve with detachable filter screens

Abstract

The invention discloses a copper valve with detachable filter screens. The copper valve with the detachable filter screens comprises a valve body, a fixing block is welded on the front surface of thevalve body, and a positioning hole is formed in the front surface of the fixing block. A positioning rod is welded to the rear surface of the valve body, and a valve cover is arranged on the valve body. A limiting block is fixedly mounted on the inner wall of the valve body, the first filter screen is arranged at the position, close to one side of the limiting block, in the valve body, and the second filter screen is arranged at the position, close to one side of the first filter screen, in the valve body. According to the copper valve, the filter screens can be rapidly replaced through the arrangement of a limiting rod and limiting holes, so that the replacing efficiency is improved; a valve rod can be prevented from being influenced by the outside humid environment through the arrangement of a protective cover, and a good protection effect is achieved; two adjacent valves can be connected through the arrangement of the positioning rod and the positioning hole, and the valves can be tidied and stacked in a normative mode. The copper valve with the detachable filter screens is easy to manufacture and convenient to popularize.

Description

technical field [0001] The invention relates to the field of valves, in particular to a detachable filter screen copper valve. Background technique [0002] Valve is a device used to control the direction, pressure and flow of fluid in the fluid system. The valve is a device that makes the medium (liquid, gas, powder) in the piping and equipment flow or stops and can control its flow. The valve can be used 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 control components in pipeline fluid delivery systems. They are used to change the passage section And the flow direction of the medium, with functions such as diversion, cut-off, throttling, check, diversion or overflow pressure relief.

AI Technical Summary

Problems solved by technology

[0003] The Chinese patent discloses a valve authorization announcement number CN205806543U. When the valve is in the open state, the pipeline and the lower part of the cavity form a fluid channel. When the valve is in the closed state, the bottom surface of the wedge-shaped valve core contacts the bottom surface of the cavity. The wedge-shaped spool is locked by the locking device. When the wedge-shaped spool slides to the bottom, the wedge-shaped spool fits closely with the end surface of the pipeline to seal the pipeline to prevent leakage. The valve has no shaft and rubber to prevent corrosion , no rotating parts, to prevent wear and tear, but when the existing valve is in use, the internal filter screen is easy to block, and it is extremely inconvenient for the user to replace the filter screen. The adjustment bolt on the valve and the valve stem are threaded The twisted ones are more easily damaged by the corrosion of humid air, and after the valves are processed, they are piled up in a scattered manner, and it is difficult to standardize the stacking. Therefore, those skilled in the art provide a detachable filter. valve, to solve the problems raised in the above-mentioned background technology
