Problems solved by technology

[0002] The cut-off mechanism of the pressure regulator refers to a valve that can automatically cut off the inlet fluid of the main channel when the controlled pressure exceeds the set value. The existing pressure regulator generally has no cut-off protection, and it is prone to accidents in some specific occasions; even if At present, there are voltage regulators with cut-off protection, but they also have defects such as complex overall structure, cumbersome assembly process, and poor sensitivity, which cause negative effects such as troublesome use and inconvenient operation.

Abstract

The invention relates to a shut-off mechanism of a voltage regulator. The shut-off mechanism comprises a shell, a diaphragm chamber shell and a balance diaphragm. The balance diaphragm is arranged in the diaphragm chamber shell and divides the diaphragm shell into an upper cavity and a lower cavity, a gas collection opening is arranged in the upper cavity, a tray in contact with the balance diaphragm is arranged in the lower cavity, and the tray is connected with a connecting rod. The shut-off mechanism is characterized in that the connecting rod is connected with a shut-off mechanism body arranged in the shell, the shut-off mechanism body comprises a rotary rod vertically connected with the shell through a first spring as well as a first swing arm, a second swing arm and a rocking bar movably connected with the shell, and a contact for connection is arranged on the rotary rod. The shut-off mechanism has the advantages of simple structure, convenience in use, capabilities of automatic or manual shut-off and manual resetting and the like.

Description

technical field [0001] The invention relates to the technical field of voltage regulators, in particular to a cut-off mechanism of the voltage regulator. Background technique [0002] The cut-off mechanism of the pressure regulator refers to a valve that can automatically cut off the inlet fluid of the main channel when the controlled pressure exceeds the set value. The existing pressure regulator generally has no cut-off protection, and it is prone to accidents in some specific occasions; even if At present, there are voltage regulators with cut-off protection, but they also have defects such as complex overall structure, cumbersome assembly process, and poor sensitivity, which cause negative effects such as troublesome use and inconvenient operation. Contents of the invention [0003] In view of the above technical problems, the present invention provides a cut-off mechanism of a pressure regulator that is simple in structure, easy to use and capable of automatic or manu...
