Variable air volume adjusting valve applied to purification equipment

Abstract

The invention discloses variable air volume adjusting valve applied to purification equipment, comprising an adjusting valve body and a protection mechanism. The protection mechanism comprises a base; connecting grooves are formed in the outer walls of the two sides of the base; flanges are arranged on the outer walls of the two sides of the connecting grooves; the inner wall of the connecting groove on one side is slidably connected with an adsorption net cage; the inner wall of the connecting groove is rotatably connected with a connecting shaft; a baffle is welded to the outer wall of the connecting shaft; a control groove is formed in the outer wall of the side, close to the connecting shaft, of the base; the connecting shaft penetrates into the control groove; a driving disc is welded to the tail end of the connecting shaft; a gear disc is rotationally connected to the inner wall of the control groove and meshed with the control disc; and a driving groove is formed below the control groove. According to the adjusting valve, a damping spring, a damping sponge, a protective pad, a buffering cotton strip, a buffering spring and a buffering cotton swab act together, so that vibration generated when the adjusting valve body works is reduced, the stability of the adjusting valve is kept, the influence of continuous vibration of the adjusting valve body in the working process on the service life of the adjusting valve body is reduced, and the service life of the adjusting valve body is prolonged.

Description

technical field [0001] The invention relates to the technical field of regulating valves, in particular to a variable air volume regulating valve applied to purification equipment. Background technique [0002] Regulating valves play a very important role in the automatic control of modern factories whose production depends on the correct distribution and control of the flowing medium. Whether these controls are energy exchange, pressure reduction or simple container filling, some final control elements are required to complete. A regulating valve acts as a variable resistance in a pipeline. [0003] The air volume regulating valve is a common part in the purification equipment, which can ensure the normal operation of the purification equipment. However, the existing regulating valve is not equipped with a protective mechanism to protect it. The regulating valve is easy to shake under the action of internal pressure during use, and long-term use will cause The control val...

Problems solved by technology

[0003] The air volume regulating valve is a common part in the purification equipment, which can ensure the normal operation of the purification equipment. However, the existing regulating valve is not equipped with a protective mechanism to protect it. The regulating valve is easy to shake under the action of internal pressure during use, and long-term use will cause The control valve is damaged, which shortens the service life of the control valve. Today's air volume control valve has a simple structure and can only perform simple adjustments. When there are impurities in the wind, the impurities and them are easy to accumulate inside the valve core, causing the valve to not operate normally. And in cold weather, the moisture in the air is easy to freeze, so that the regulating valve freezes, causing the regulating valve to fail to work.
