Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] The pressure limit adjustment device of this embodiment can be installed on the inner wall of the fluid chamber (not shown). at that window. The pressure limiting adjustment device can also be integrated on a standard flange to form a complete adjustable pressure limiting element. When in use, the element is directly connected to the flange window of the fluid chamber or pressure chamber.

[0028] Such as figure 1 As shown, the pressure limit regulati...

Abstract

The invention discloses a pressure limiting and adjusting device. The device is mounted on the inner wall of a fluid chamber, the device comprises a main body, a blocking piece and a fastener, wherein the main body comprises a first wall surface connected with the fluid chamber and a second wall surface connected to the first wall surface, the first wall surface and the second wall surface encloses an inner cavity which communicates with the fluid chamber, and the first wall surface is provided with a first through hole which communicates with the inner cavity and the outside; the blocking piece is arranged on one side, away from the inner cavity, of the first wall surface and provided with an edge part, and the area of the edge part is gradually reduced in the direction away from the inner cavity; one end of the fastener is connected with the blocking piece, and the other end of the fastener is fixedly connected with the second wall surface; and when the fluid pressure in the fluid chamber is smaller than or equal to a preset value, the edge part abuts against the first wall surface, the first through hole is blocked by the blocking piece, when the fluid pressure in the fluid chamber is larger than the preset value, the edge part deforms in the direction away from the first wall surface under the action of the fluid pressure, and therefore, fluid in the fluid chamber flows to the outside from the first through hole. According to the scheme, pressure relief of the fluid chamber can be regulated and controlled.

Description

technical field [0001] The invention relates to the technical field of pressure regulation, in particular to a pressure limit regulation device. Background technique [0002] During chemical reaction or heat treatment, some samples need to be placed in an atmosphere environment with a certain positive pressure for processing. Therefore, it is necessary to feed enough atmosphere gas into the gas chamber to ensure the concentration of the atmosphere gas in the atmosphere environment. When the gas chamber is filled with too much atmospheric gas, it will cause the air chamber pressure to be too high, and in severe cases, it will cause risks such as damage to the gas chamber. Contents of the invention [0003] In order to overcome the defects in the prior art, an embodiment of the present invention provides a pressure limit adjustment device, which is used to solve the above problems. [0004] The embodiment of the present application discloses: a pressure limit adjustment dev...
