Description

Technical Field

[0001] The utility model relates to the technical field of pipeline valves, and more particularly to a remote-controlled pipeline control valve. Background Art

[0002] A fire water pipe control valve is a control valve that can remotely detect fire water pressure and control the degree of valve opening and closing. However, commonly used remotely controlled pipe control valves require more space on the pipe surface during assembly, and it is not easy to modify existing pipe control valves. At the same time, during the control process, the control stability may be reduced due to belt wear and slippage.

[0003] For example, announcement No. CN221145337U discloses a fire water pipe control valve, which includes a valve pipe, a control device, an adjusting rod and a valve. The valve pipe has open pipe interfaces on both sides. The valve is rotatably installed in the valve pipe. The adjusting rod is plugged into the top of the valve shaft. The control device is fixedly installed on the valve pipe. A pressure sensor is fixedly installed at the lower end of the control device. A motor is fixedly installed on the side of the control device. A synchronous belt is connected between the motor and the adjusting rod.

[0004] It can be seen from the above-mentioned public scheme that the remote control device of the control valve is fixed on the surface of the valve pipeline, occupying a large position, and the valve stem is controlled by a synchronous belt. It is not only difficult to modify the existing pipeline control valve, but the synchronous belt is prone to wear and slip during use, which leads to insufficient rotational stability of the control valve stem and reduces the control stability.
