Automatic control type butterfly valve

Abstract

The invention discloses an automatic control type butterfly valve which comprises a driving mechanism, a handle, a valve deck, a sponge protection plate, a buffering device, a pressure sensor, a butterfly plate, a cooling device, a valve body, a seal ring, a valve rod, a sealing gasket, a control board, an indicator lamp and a PLC. The seal ring is attached and fixed to the inner side of the valvebody. The pressure sensor is fixed to one side of the seal ring through a bolt. The valve deck is fixed to the top of the valve body through a bolt. The sealing gasket is installed and embedded in the joint of the valve deck and the valve body. The valve rod penetrates through the valve deck and the valve body. The butterfly plate is fixed to the outside of the valve rod through a bolt. The handle is installed on the valve rod. The driving mechanism is connected with the top end of the valve rod. The control board is fixed to one side of the driving mechanism through a bolt. The indicator lamp is installed at the center of the top of the control board. The butterfly valve has the advantages of being high in cooling property, good in buffering and protecting effect and high in intelligentdegree.

Description

technical field [0001] The invention relates to the technical field of butterfly valves, in particular to an automatic control butterfly valve. Background technique [0002] Butterfly valve is also called flap valve. It can be used for switch control of low-pressure pipeline medium. Most butterfly valves refer to a valve whose closing part is a disc and rotates around the valve shaft to achieve opening and closing. [0003] Butterfly valve is one of the important execution units in the field of industrial automation control. It belongs to a branch of valves and electric regulating valves, and is widely used in fields such as textiles, power stations, petrochemicals, heating and refrigeration, pharmaceuticals, shipbuilding, metallurgy, light industry and environmental protection. It can be used as shut-off valve, control valve and check valve in piping system. And in the metallurgical steel and shipbuilding industry, has a very high reputation. [0004] However, in the exi...

AI Technical Summary

Problems solved by technology

[0004] However, in the existing butterfly valve, there are problems of weak heat dissipation, poor buffer protection effect and low degree of intelligence

The service life and use effect of the internal sealing elements of the butterfly valve are often affected by the high temperature of the inflowing medium, and when impacted or vibrated, the sealing performance of the connection is often affected, and most butterfly valves are intelligent. low level
