Abstract

The invention discloses a pipeline switching-on and switching-off device and system. According to the switching-on and switching-off device, a valve is switched on and switched off in the manner thatan air bag driven by a lead screw and a hose serves as a valve element of the traditional valve, and the purpose of switching on and switching off a pipeline is achieved. Specifically, an air compressor serves as an air source, the air bag is inflated or the air in the air bag is discharged by controlling air discharging and air feeding of the air compressor, and then switching-off, switching-on and flow adjustment of the pipeline are achieved. To facilitate air inflation and air discharging of the air bag, the pipeline switching-on and switching-off device is further internally provided witha lead screw stepping motor, rapid air inflation and rapid air discharging of the air bag can be realized through match between the lead screw stepping motor and the air compressor, and rapid adjustment of the flow is realized. The air bag serves as the valve element of the valve for the first time, and compared with a previous metal valve element, the air bag valve element has the advantages of being resistant to impurities, capable of realizing stepless adjustment of the flow, long in service life, precise in flow adjustment and the like.

Description

technical field [0001] The invention discloses the technical field of a pipeline switch, in particular to a pipeline opening and closing device and a pipeline opening and closing system thereof. Background technique [0002] There are various intricate piping systems on ships and other buildings, and various flow media (some even high temperature, strong corrosive and other dangerous fluids) flow among them. [0003] At present, most of the control valves are manually operated, and there are the following problems: the flow cannot be accurately controlled; if the time between opening and closing is long, it is easy to forget to close the valve in time, causing the flow to exceed the target value, resulting in production errors; When the flowing medium is a high-temperature or highly corrosive dangerous liquid, once the operation is wrong, it is easy to cause bodily injury to the operator and bring serious consequences. [0004] In view of this, how to develop a new pipeline...
