Problems solved by technology

[0003] In the current check valves, there are many valve slices that often cannot check back or cannot completely check back. The main reason is not only because the valve slices inside the valve are often stuck, which will make the valve slices unable to check. Good closure affects normal work, and the check effect of a single valve plate is poor and easy to leak

Embodiment Construction

[0011] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0012] Such as figure 1 As shown, a water pipe check valve swivel frame includes a fixed frame 1, a limit frame 2 and a rotary bolt 3, the fixed frame 1 is fixedly connected with the rotary bolt 3, and the limit frame 2 is rotatably installed on the fixed frame through the rotary bolt 3. On the frame 1, the rotating bolt 3 is provided with a 90-degree fan-shaped rotating groove 4, and a rotating baffle 5 is arranged on one side of the rotating groove 4 on the rotating bolt 3, and the rotating baffle 5 and the limit frame 2 are connected to each other. Vertically, there are two rotating baffles 5 and two rotating slots 4 and they are arranged symmetrically with respect to the center of the rotating bolt 3 . The length of the rotary baffle 5 is t...

Abstract

The invention discloses a water pipe check valve rotation rack and relates to the technical field of valves. The water pipe check valve rotation rack is characterized by comprising a fixed rack, a limit rack and a rotary bolt. The fixed rack is fixedly connected with the rotary bolt. The limit rack is rotatably mounted on the fixed rack through the rotary bolt. Two 90-degree sector rotary grooves are formed in the rotary bolt. One lateral side, located on the rotary grooves, of the rotary bolt is provided with two rotary retaining plates which are vertical to the limit rack. The rotary retaining plates and the rotary grooves are symmetrical relative to the center of the rotary bolt. The water pipe check valve rotation rack is simple in structure, reasonable in design, convenient to use, good in check effect, and less prone to getting stuck and leakage.

Description

Technical field: [0001] The invention relates to the technical field of valves, in particular to a water pipe check valve swivel frame. Background technique: [0002] Check valve, also known as one-way valve or check valve, is used to prevent the medium in the pipeline from flowing backward. Typically, fluid under pressure opens the valve's disc and flows from the inlet side to the outlet side. When the pressure on the inlet side is lower than that on the outlet side, the disc automatically closes the channel under the action of fluid pressure and its own gravity to prevent the fluid from flowing backward. [0003] In the current check valves, there are many valve slices that often cannot check or cannot completely check. The main reason is not only because the valve slices inside the valve are often stuck, which will make the valve slices unable to check. A good closure will affect the normal work, and the check effect of a single valve plate is poor, and it is easy to le...
