Problems solved by technology

However, the filter in this kind of ball valve is easy to accumulate impurities in the connection between the valve core and the valve body, and the filter in it cannot be taken out for cleaning or replacement, and the accumulated impurities are easy to block the pipeline. The cylindrical filter at the bottom is not filtered The function is only to collect impurities, and the height of the cylindrical filter is relatively short compared to the overall height of the valve body. In the state of unstable water flow, it is easy to cause impurities, pollutants, etc. to flow back, and the collection of impurities is not complete.

Abstract

The invention discloses a filter ball valve. The valve comprises a valve body and a valve element rotatably arranged in the valve body, wherein the valve body is provided with an inlet and an outlet,and the valve element is provided with an upper cavity, a lower cavity and a circulating hole communicating with the upper cavity and the lower cavity, wherein the upper cavity communicates with the inlet, and the lower cavity communicates with the outlet; and the valve further comprises a filter screen, at least one part of the filter screen is arranged in the lower cavity, the filter screen is detachably connected with the valve element, and at least one part of the filter screen is arranged between the lower cavity and the outlet. According to the valve, the filter screen can be replaced from an end cover, so that pollution discharge cleaning is convenient, and the pollution discharge filtering effect of impurities is good.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a filter ball valve. Background technique [0002] At present, in the civil or industrial fields, all kinds of water supply, heating, and gas supply pipeline systems are equipped with various measuring instruments and equipment and other components. As the use time increases, the impurities in various flowing media Accumulated in the pipeline and various parts used, causing pipeline blockage or component wear, affecting the accuracy of various measuring instruments and the service life of equipment. [0003] In order to solve these problems, various filtering devices and valves have been installed in the pipeline to filter and clean up the impurities accumulated in the pipeline during long-term use, so as to ensure the normal operation of instruments and equipment. [0004] Existing ordinary filter ball valves such as Patent No. 201280017999.X are formed by adding a filter to the...
