Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 , a one-way valve, comprising a valve stem 1, a valve body 2, a gate plate 3, a valve cover 4, a hand wheel 5, and a check valve core assembly 6, and the valve body 2 is provided with a water inlet 21 and a water outlet 22, The check valve spool assembly is located in the cavity of the water inlet 21 and is combined with the cavity of the water inlet 21 to form a check valve. The check valve spool assembly 6 includes a spool 23 located in the cavity of the water inlet 21, The spring 24, the valve seat 25, the support frame 26 of the fixed check valve core assembly connected to the valve seat 25, the gasket 27 is arranged between the support frame 26, the valve seat 25 and the cavity of the water inlet 21 to play a sealing role. The outer end of the valve seat 25 is clamped by the retaining ring 28 arranged on the groove of the cavity ...

Abstract

The invention discloses a one-way valve. The one-way valve comprises a valve rod, a valve body, a gate plate, a valve cover, a hand wheel and a check valve element assembly. The valve body is providedwith a water inlet and a water outlet. The check valve element assembly is arranged in a cavity of the water inlet and combined with the cavity of the water inlet into a check valve. The valve coveris provided with at least one wiring hole, and the valve body is provided with a wiring hole. The outer end of the water inlet is further connected with a filter pipe. According to the one-way valve,a gate valve and the check valve are combined, the dual functions of the two valves are achieved, and an original combined complex structure is simplified. The valve cover and the valve body are bothprovided with the wiring holes, a wire penetrates the two holes of the valve cover and the valve body for tightening, and a user is effectively prevented from stealing water. Meanwhile, the one-way valve has a filter function, and valve element damage is effectively prevented.

Description

technical field [0001] The invention relates to a valve, specifically a one-way valve. Background technique [0002] Union one-way valves are widely used in villages, towns, cities, one-household-one-meter projects and valves in various occasions. It cuts off (or connects) the medium in the pipeline manually and can automatically operate to prevent the backflow of the medium and the water caused by the backflow. Hammer phenomenon damage to accessories in pipe fittings. In general, to cut off the medium and prevent the backflow of the medium, two valves, one shut-off valve and one check valve, are usually used to achieve the purpose through combination, which has the advantages of cumbersome installation, large waste of materials, resulting in low utilization rate and energy consumption. major defects. Moreover, the existing one-way valve does not have a filtering function, and the valve core is easily damaged. Contents of the invention [0003] The object of the present...
