Problems solved by technology

There is only one butterfly plate in the valve in the prior art, which cannot effectively throttle and divert the flow during the control process, and the pressure it receives is also high. Even after the valve is used for a long time, it is easy to crack and cause the valve body to break

Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing;

[0015] see figure 1 , figure 2 As shown, the valve includes a valve body 3, a rotating shaft 6 and a butterfly plate 5. Flanges 1 are provided at the openings on both sides of the valve body 3, and a reinforcing rib 2 is provided in the middle of the valve body 3, and a reinforcing rib 2 is provided on the reinforcing rib 2. There is a valve switch 4, and the valve body 3 corresponding to the valve switch 4 is provided with three longitudinal rotating shafts 6 on which there are three butterfly plates 5, and the butterfly plates 5 rotate in the valve body 3 around the rotating shaft 6.

[0016] The three butterfly plates 5 are composed of two arc-shaped plates of the same size and a rectangular plate with circular arcs at both ends. The combination of the three butterfly plates is circular and has the same diameter as the inner wall of the valve body 3, which can To achi...

Abstract

The invention relates to a valve which comprises a valve body, rotating shafts and butterfly plates. Flanges are arranged at ports of two sides of the valve body, a reinforcing rib is arranged in the middle of the valve body, a valve switch is arranged on the reinforcing rib, three longitudinal rotating shafts are arranged in the valve body corresponding to the valve switch, and three butterfly plates are arranged on the rotating shafts and rotate in the valve body around the rotating shafts. The valve has the advantages of simplicity in operation, long service life, fine flow control effect and the like.

Description

technical field [0001] The invention relates to the technical field of valve equipment, in particular to a valve. Background technique [0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. The valve is a device that makes the medium (liquid, gas, powder) in the piping and equipment flow or stop and can control its flow. The valve is a control component in the pipeline fluid delivery system. It is used to change the passage section and the flow direction of the medium. It has the functions of diversion, cut-off, throttling, check, diversion or overflow pressure relief. There is only one butterfly plate in the valve in the prior art, which cannot effectively throttle and divert flow during the control process, and is also subjected to high pressure. Even after the valve is used for a long time, cracks are prone to appear and the valve body will break. Contents of the invention [0003] The purpose of the present invent...
