Description

Technical Field

[0001] The utility model relates to the technical field of electric sealed valve connection, in particular to a connection component for an electric sealed valve. Background Art

[0002] An electric sealed valve is an electrically controlled valve that controls the opening and closing of the valve by driving the valve stem through an electric motor, thereby controlling the flow and pressure of the fluid. When the motor drives the valve stem to rotate, the valve stem pushes the valve open or closed, thereby controlling the flow and pressure of the fluid. It is widely used in industries such as petroleum, chemical industry, electric power, metallurgy, and water treatment. During the use of the electric sealed valve, it is usually connected to the pipeline through a connecting component.

[0003] Most of the existing electric closed valve connection components place a rubber gasket at the connection between the electric closed valve and the pipeline to increase the sealing line of the connection, and then connect the electric closed valve to the pipeline through bolts. The connection structure is relatively simple. With long-term use, the rubber gasket is prone to aging and damage, and there is a risk of leakage. For this reason, we propose a connection component for an electric closed valve. Utility Model Content

The airbag 803 is bonded to the arc block 801, and the airbag 803 is annular when viewed from the side.

[0024] The operator manually rotates the threaded rod 6 through the handwheel 7, so that the arc block 801 presses the airbag 803, so that the airbag 803 is tightly pressed against the connection between the connecting pipe 3, the sealing ring 2 and the valve body 1. The airbag 803 can tightly fill the connection gap between the connecting pipe 3, the sealing ring 2 and the valve body 1, further reducing the risk of gas leakage inside the connecting pipe 3.
