Abstract

The invention relates to the technical field of valves, in particular to a stop check valve. The stop check valve comprises: a valve body shell, wherein the two ends of the valve body shell can be detachably connected with flange plates; a control box, which is arranged on the outer surface of the valve body shell; a control processor, which is arranged in the control box; a wireless transmissiondevice, which is arranged in the control box and used for establishing communication connection between the control processor and a control indoor server; an authentication and identification device,which is arranged on the outer surface of the control box, is electrically connected with the control processor and is used for acquiring identity information of an operator; an indicator light, whichis arranged on the control box and is electrically connected with the control processor; and pressure sensors, which are embedded in the outward sides of the flange plates and are electrically connected with the control processor.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a stop check valve. Background technique [0002] With the rapid development of social economy, the stop-check valve (stop-check valve) is a multi-purpose valve with the functions of stop valve and check valve. Its structure is similar to that of globe valve, but the stem and disc are not fixedly connected. When the valve stem is lowered to press the disc tightly on the valve seat, it acts as a stop valve; when the valve stem rises, it acts as a check valve. On pipelines that need to install stop valves (or gate valves) and check valves at the same time (such as the outlet end of water pumps), or in places where the installation position is limited (such as ships), using stop and check valves can save installation costs and space. . [0003] At present, the existing cut-off check valve does not have the function of alarming when it is intentionally forcibly dismantled or loosen...
