Water supply valve with quickly changeable filter element

Abstract

The invention discloses a water supply valve with a quickly changeable filter element. The water supply valve with the quickly changeable filter element comprises a valve body, an upper bonnet, a lower bonnet, the filter element, a valve element, a reset spring and an air cylinder, wherein an accommodating cavity is formed in the valve body; a water inlet end and a water outlet end which communicate with the accommodating cavity are arranged on the valve body; the upper bonnet detachably covers the upper end of the valve body; the lower bonnet covers the lower end of the valve body; the filter element, the valve element and the reset spring are sequentially assembled in the accommodating cavity of the valve body from top to bottom; the air cylinder is fixedly mounted on the upper bonnet; the upper end of the filter element penetrates through the upper bonnet and is connected with a piston rod of the air cylinder; the lower end of the filter element is propped against the upper end of the valve element; two ends of the reset spring are respectively propped against the valve element and the lower bonnet; the valve element can move vertically along the accommodating cavity; and a limiting step for limiting the maximum upward movement stroke of the valve element is arranged on a wall of the accommodating cavity. By the water supply valve with the quickly changeable filter element, the technical problem that a filter element of the traditional water purifying valve is difficult to change is solved effectively.

Description

technical field [0001] The invention relates to the technical field of water supply valves, in particular to a water supply valve capable of rapidly replacing filter elements. Background technique [0002] With the development of social industrialization, the quality of tap water in cities is getting worse and worse. Residents in many places are afraid to drink tap water. Nowadays, tap water purification devices are more and more popular with people, so that people can drink "safe water".
