Problems solved by technology

[0003] At present, the gaskets of fluorine-lined pneumatic bellows control valves mostly use simple rubber gaskets. The pneumatic bellows control valves will be impacted by air pressure during use. With the vibration and friction along the direction of the valve body during the practical process, As a result, the rubber gasket at the joint is prone to breakage and cracks during the wear process, which not only affects the service life, but also brings safety hazards

Embodiment Construction

[0019] For the following, through the description of the examples, the specific implementation of the present invention, such as the manufacturing process involved, the operation and use method, etc., will be described in further detail, so as to help those skilled in the art to have a more complete concept of the invention and the technical solution of the present invention. , accurate and in-depth understanding.

[0020] In order to solve the problems in the prior art, the present invention provides a gasket for a fluorine-lined pneumatic bellows regulating valve. The gasket includes the following components in mass percentages: 70-95% of the rubber body, and 5-30% of buffer sheets interspersed in the rubber body %.

[0021] Through the cooperation of the rubber body and the buffer sheet interspersed in the rubber body, the breakage and cracking of the gasket caused by destructive actions during use can be improved. The insertion of the buffer sheet will increase the strengt...

Abstract

The invention discloses a fluorine-lined pneumatic bellows regulating valve gasket, and relates to the technical field of gaskets. The breakage and cracking phenomena of the gasket due to destructiveaction and the like in the using process are eliminated through cooperation of a rubber body and a buffer plate inserted into the rubber body; on one hand, the strength of the rubber body is improvedthrough insertion of the buffer plates, and on the other hand the effect of gathering the rubber body stably is achieved; the situation that debris of the rubber body falls off due to friction and thelike is avoided, and the life cycle of the gasket is prolonged.

Description

technical field [0001] The invention relates to the technical field of gaskets, in particular to a gasket for a fluorine-lined pneumatic bellows regulating valve. Background technique [0002] Valves are widely used in the national economy dominated by industry. All walks of life need various pipelines to transport various media, such as steel mills, oil refineries, power plants, chemical plants, etc. Pipelines for many media such as water, steam, air, oil and other corrosive media. The valve is a kind of pipeline accessories, mainly used to change the flow direction of the medium or change the section of the channel, and adjust and control the movement of the medium in the pipeline. For the integrity of the seal during the installation of the valve, the gasket is required as a transition part during the connection between the valve and the pipeline. [0003] At present, the gaskets of fluorine-lined pneumatic bellows control valves mostly use simple rubber gaskets. The pn...
