Embodiment Construction

[0034] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. Wherein, similar elements in different implementations adopt associated similar element numbers. In the following implementation manners, many details are described for better understanding of the present application. However, those skilled in the art can readily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the application are not shown or described in the description, this is to avoid the core part of the application being overwhelmed by too many descriptions, and for those skilled in the art, it is necessary to describe these operations in detail Relevant operations are not necessary, and they can fully understand the relevant operations according to the description in the specification and genera...

Abstract

The invention discloses a vacuum plate valve, which comprises a valve body, a valve core and a driving mechanism. The valve body has a valve chamber, and both sides of the valve body are provided with a first opening and a second opening. The valve core includes a bearing part, a first support arm, a second support arm, a first sealing plate and a second sealing plate. Since the lengths of the first support arm and the second support arm are all within the preset range, the pressing angle formed by the first support arm and the second support arm is greater than or equal to 45°, so that the first support arm and the second support arm The horizontal component force on the support arm is greater than or equal to the vertical component force, forming a greater sealing thrust on the first sealing plate and the second sealing plate respectively, improving the sealing performance of the vacuum plate valve, so that the vacuum plate valve can operate under high temperature and high pressure. Work normally in the environment for a long time.

Description

technical field [0001] The invention relates to the technical field of gate valves, in particular to a vacuum plate valve. Background technique [0002] The plate valve is one of the most commonly used cut-off valves, which is mainly used to connect or cut off the medium in the pipeline, and is not used to adjust the flow of the medium. The range of pressure, temperature and diameter used is very large, especially for medium and large diameter pipes. [0003] Vacuum plate valve is a kind of plate valve. In addition to realizing the physical isolation of fluid, the vacuum plate valve can also block the transfer of heat field. However, the airtightness requirements of vacuum plate valves are better than ordinary plate valves. The current vacuum plate valves adopt the same airtight structure as ordinary plate valves, which leads to air leakage after working in a high temperature and high pressure environment for a period of time. , the valve fails.
