Abstract

The invention provides a mechanical emergency shutdowm valve which comprises a valve element, a regulation mechanism and a self-lock insertion rod. An annular self-lock opening clamping groove and an annular self-lock closing clamping groove are formed in the valve element; the regulation mechanism comprises two transverse drive parts and a regulation support clamped between the transverse drive parts, the external air pressure drives the regulation support to move transversely by controlling at least one transverse drive part, a concave guide rail with two high sides high and low middle is arranged on the regulation support in the transverse direction, and downward concaved limit clamping grooves are formed in the two ends of the guide rail; the self-lock insertion rod can penetrate through the regulation support in a longitudinal moving mode, is erected on the guide rail and extends to one side of the valve element, the self-lock insertion rod relatively slides on the guide rail to drive the self-lock insertion rod to do reciprocation motion in the longitudinal direction, and the extension end of the self-lock insertion rod is fixedly clamped with or separated from the self-lock opening clamping groove and the self-lock closing clamping groove. The mechanical emergency shutdowm valve is easy and convenient to install and regulate and reliable in operation.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a mechanical emergency cut-off valve. Background technique [0002] The emergency cut-off valve can realize the automatic cut-off function of wellhead overpressure and single well gas production pipeline leakage or burst pipe, so that the foreseeable risk can be controlled and the loss caused by the risk can be minimized. The core of the emergency shut-off valve is mainly to adjust the ultra-low pressure and ultra-high pressure. The emergency shut-off valves used in the prior art include mechanical, hydraulic, and pressure sensing types. Among them, the mechanical emergency cut-off valve is mainly adjusted through a lever structure to drive the valve core to move, so as to achieve the purpose of moving and closing the valve core under ultra-low pressure and ultra-high pressure conditions. However, the lever type used in the prior art has a complicated structure, which makes it ve...
