Replacement damage type continuous wear-resistant pneumatic high-temperature butterfly valve

Abstract

The invention discloses a replacement damage type continuous wear-resistant pneumatic high-temperature butterfly valve, and belongs to the technical field of valve bodies. It is achieved that when thepneumatic high-temperature butterfly valve is used, repair regeneration liquid is injected into a storage bin, and enters a T-shaped shell through a liquid inlet pipeline, then, a valve plate rotates, at the moment, an initial abrasion film replaces a sealing block to rub the inner wall of a valve body, the sealing performance of the sealing block and the valve body is maintained under the elastic effect of the initial abrasion film, meanwhile the initial abrasion film is continuously consumed along with use of a valve body, meanwhile, a liquid compression plate continuously extrudes the repair regeneration liquid in a wear-resistant repair ball under the elastic action of a second compression spring to continuously output the liquid through a communicating hole, the initial abrasion filmis solidified and supplemented under the thermosetting action, continuous regeneration is conducted while replacement consumption is conducted, loss of the sealing block is reduced, the service lifeof the valve body is prolonged, and therefore, the mechanical loss of the pneumatic high-temperature butterfly valve in use is reduced, the possibility of leakage accidents is reduced, and the use safety is improved.

Description

technical field [0001] The invention relates to the technical field of valve bodies, and more specifically relates to a replacement damaged continuous wear-resistant pneumatic high-temperature butterfly valve. Background technique [0002] The pneumatic butterfly valve is composed of a pneumatic actuator and a butterfly valve. The pneumatic butterfly valve is a pneumatic valve that uses a circular butterfly plate that rotates with the valve stem to open and close to realize the activation action. It is mainly used as a cut-off valve, and it can also be designed to have the function of adjustment or section valve and adjustment. The butterfly valve operates at low pressure and large It is used more and more on medium-bore pipes. Pneumatic butterfly valve classification: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, carbon steel pneumatic butterfly valve. The main advantages of the pneumatic butterfly val...

Problems solved by technology

[0004] In the actual scene application, the butterfly valve is in use, after long-term rotation, mechanical loss occurs between the valve plate and the valve body, the airtightness is reduced, it cannot be effectively sealed, and it is easy to produce loopholes, which will cause serious consequences such as leakage. However, there are no effective measures for this, so it is necessary to prevent and deal with it.
