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 core assembly, wherein a water inlet and a water outlet are formed in the valve body, the check valve core assembly is arranged in a cavity body of the water inlet to form a check valve, at least one threading hole is formed in the valve cover, a threading hole is formed in the valve body, and a filter pipe is further connected to the outer end of the water inlet. According to the one-way valve, a gate valve and the check valve are integrated, so that the one-way valve has dual functions of two valves, and an original complex combined structure is simplified; the threading holes are formed in the valve cover and the valve body, and the valve cover and the valve body are stringed by threads, so that water is effectively prevented from being stolen by users; and furthermore, the one-way valve further has a filter function, so that the damage of the valve core 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...
