water filter valve

Abstract

The invention discloses a filtering water supply valve. The filtering water supply valve comprises a valve body, an upper bonnet, a lower bonnet, a filter element, a valve element, a reset spring and a valve handle, 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 arranged in the accommodating cavity of the valve body from top to bottom; the valve handle is hinged to the valve body; a chute is formed in one end of the valve handle; the upper end of the filter element penetrates through the upper bonnet and is in sliding fit with the chute through a latch and the valve handle; 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 along the accommodating cavity in the vertical direction; and a limiting step for defining the maximum upward movement stroke of the valve element is arranged on a wall of the accommodating cavity. By the filtering water supply valve, the technical problem that a filter element of the traditional water purification valve is difficult to change is solved effectively.
