Non-leakage intelligent electric butterfly check valve

Abstract

The invention discloses a non-leakage intelligent electric butterfly check valve which comprises a valve seat and an intelligent electric execution device arranged on the valve seat. The valve seat comprises a valve seat body, a disc arranged in the valve seat body and a supporting frame arranged above one side of the valve seat body. The intelligent electric execution device comprises a drive motor installed on the supporting frame and an intelligent control box arranged on one side of the drive motor. The section of the disc is in a Z shape, the disc comprises a rotary shaft and semicircularsteel sheets arranged on two sides of the rotary shaft, the edges of the semicircular steel sheets are sunken, and sealing rings matched with the sunken positions correspondingly in an embedded modeare arranged at the sunken positions. As the disc is in the Z shape, the rotary shaft is connected with the drive motor, and the sealing rings fixedly connected with the valve seat body are arranged at the edges of the semicircular steel sheets, the sealing effect can be effectively improved; and in addition, the valve can be driven through the intelligent electric execution device and has the advantages of long service life, intelligent controllability and high sealing reliability.

Description

technical field [0001] The invention relates to a butterfly-shaped intelligent electric check valve without leakage. Background technique [0002] With the continuous development of production level and scale, pipeline transportation has gradually become the fifth largest transportation mode after railway, highway, water transportation and air transportation. As the main method of pipeline transportation, pneumatic conveying has been widely used in bulk material transportation in modern industry, especially the transportation of fly ash and pulverized coal in power plants. Pneumatic conveying has incomparable advantages compared with other conveying methods: flexible piping, unrestricted conveying path, and can be closely integrated with the production process; no pollution, good safety, high reliability; easy to install and realize automatic control; especially suitable for conveying Powder, granular, fibrous and blade-like materials are conducive to the secondary developm...

AI Technical Summary

Problems solved by technology

However, the existing electric check valves have a simple structure. Under corrosive, toxic and harmful process conditions, such valves often have poor sealing performance, easy leakage, easy perforation of the shell, and short service life, which cannot meet the long-term effective transportation of gas and liquid. Special requirements for toxic media; on the other hand, the valve plate of the existing electric check valve is completely flat, and there is no obvious one-open and one-close control of the valve seat, that is, there is still a gap after closing, resulting in gas Leakage, therefore, the sealing performance of the sealing part of the valve is not good, and it cannot prevent the leakage of the medium well

[0004] Therefore, in summary, the existing valves have the problems of short service life, inconvenient manipulation and low sealing reliability.
