Example Embodiment

[0012] See figure 1 , The present invention relates to a plug valve with an alarm, including a valve body 1, a valve seat 2 is arranged in the middle of the valve body 1, and the valve seat 2 and the valve body 1 are arranged separately. A valve seat cushion ring 3 and a valve seat sealing ring 4 are provided between the seat 2 and the valve body 1, a cock 5 is provided in the middle through hole of the valve seat 2, and a cock 5 is provided between the cock 5 and the valve body 1 Sealing ring 6, the top of the valve body 1 is connected with the screw cap 7 through threads, the top of the screw cap 7 is hinged with a handle 8 arranged horizontally, and the screw cap 7 is rotated by the handle 8. The front side tube of the valve body 1 An alarm is set in the road, which can monitor the flow rate of the plug valve. After comparing with the normal flow rate, it will alarm if it is higher or lower than the standard.
[0013] This kind of plug valve with alarm has a movable connection between the valve seat and the valve body. When maintenance is needed, the valve seat and the plug can be disassembled together, which is convenient for disassembly and assembly and improves the maintenance efficiency; at the same time, the valve seat and the valve body , And a plug sealing ring and packing are arranged between the plug and the valve body, which has good sealing performance and can prevent leakage at high and low pressures.
