Abstract

The invention discloses a cut-off ball valve, comprising: a valve body, a valve seat, a valve stem and a valve core, the valve body is a side-mounted valve body, a valve seat and a valve core are installed in the valve body, and the valve seat is installed in the valve body Between the valve core and the valve seat, the cross-sectional shape of the valve seat is "<", the bottom of the valve stem passes through the top of the valve body and is installed on the top of the valve core, the top of the valve body is fixedly installed with a bracket, and the top of the bracket is installed with an actuator. The actuator is fixedly connected with the valve stem, and the actuator is a pneumatic actuator. The technical purpose of the present invention is to provide a shut-off ball valve with fast opening and more reliable sealing. This shut-off ball valve can quickly cut off the medium in the pipeline, thereby ensuring the safety of production, and has floating sealing performance.

Description

technical field [0001] The invention relates to the field of valves, in particular to a cut-off ball valve. Background technique [0002] The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small rotational torque to close tightly, and the cut-off ball valve is a kind of cut-off valve. [0003] However, the power mechanism of the existing cut-off ball valve is usually manual, and when the volume of the cut-off ball valve is large, it is usually laborious and slow to operate, so that it cannot be cut off quickly during emergency cut-off; and the existing cut-off ball valve The sealing performance is not good, and there is a problem of hidden leakage, which is easy to cause production accidents. Contents of the invention [0004] In view of the deficiencies of the above-mentioned ball valve, the technical purpose of the present invention is to provide a shut-off ball valve...
