Anti-vibration butterfly valve

Abstract

The invention discloses an anti-vibration butterfly valve, and relates to the technical field of valve equipment. The anti-vibration butterfly valve comprises a valve body, a water inlet pipe, a drainage pipe, a butterfly plate component, a frame body, a rack, a clamping part and a limiting mechanism. The anti-vibration butterfly valve has the beneficial technical effects that the situation that the valve is opened or closed by mistake due to the fact that the valve body is vibrated because of being impacted can be avoided, when the anti-vibration butterfly valve is in an opened state, and aclamping block on the clamping part can keep the anti-vibration butterfly valve in the opened state; when the anti-vibration butterfly valve is in a closed state, the anti-vibration butterfly valve can be kept in the closed state by adjusting the direction of the clamping block on the clamping part, the left end of the valve body is fixedly connected with and communicates with the water inlet pipe, the right end of the valve body is fixedly connected with and communicates with the drainage pipe, the butterfly plate component is arranged in the middle of the valve body, the frame body is fixedly connected to the upper end of the valve body, the rack is arranged on the frame body, and the butterfly plate component is in transmission connection with the rack. The clamping part is fixedly connected to the frame body, the clamping part is clamped on the rack, the limiting mechanism is connected on the clamping part in a sliding fit manner, and the limiting mechanism is connected with the clamping part.

Description

technical field

[0001] The invention relates to the technical field of valve equipment, in particular to an anti-vibration butterfly valve. Background technique

[0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure. Butterfly valve is suitable for producing furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection, building water supply and drainage and other engineering systems It is used to adjust and cut off the flow of medium on pipelines that transport various corrosive and non-corrosive fluid media. However, when the butterfly valve in the prior art is in use, when the fluid pressure difference in the flow channel of the valve body fluctuates greatly, The spool will vibrate when subjected to continuous impact, and even automatically fall to close the flow channel of the valve body; therefore, we propose an anti-vibration butterfly valve t...
