Embodiment
Below in conjunction with accompanying drawing, describe preferred embodiment of the present utility model in detail.
Embodiment mono-
Refer to Fig. 1, the utility model has disclosed a kind of automatic reflux valve detection system, for detection of automatic reflux valve 101; Described system comprises: controller and connecting line after controller, bypass controller, valve before operation valve 106, valve after operation valve 104, bypass control valve 105, valve before master station, water tank 102, water pump 103, valve.Described control desk can be computing machine.
Controller and water pump 103 after controller, bypass controller, valve before described master station connection valve, send control commands to controller after controller, bypass controller, valve before valve and water pump 103.Operation valve 104 before controller connection valve before described valve, by the aperture of operation valve before the order operation valve of reception master station; Described bypass controller connects bypass control valve 105, controls the aperture of bypass control valve by receiving the order of master station; Operation valve 106 after controller connection valve after described valve, by the aperture of operation valve after the order operation valve of reception master station.Before described valve, after controller, bypass controller, valve, controller can be all electric controller.
Described water tank 102 is operation valve 106 after operation valve 104, bypass control valve 105, valve before connection valves respectively, and before valve, operation valve 104 connects water pumps 103, and described automatic reflux valve 101 connects respectively operation valve 106 after water pump 103, bypass control valve 105, valve.
After described automatic reflux valve 101 and valve, between operation valve 106, be provided with first flow meter 107, the first pressure transducer 108, between automatic reflux valve 101 and bypass control valve 105, be provided with the second flowmeter 109, the second pressure transducer 110, between automatic reflux valve 101 and water pump 103, be provided with the 3rd pressure transducer 111.
Refer to Fig. 2, the automatic reflux valve that the utility model detection system detects comprises: lower valve body 1, upper valve body 2, main valve stem 5, main valve clack 6, bypass valve rod 7, bypass flap 8, expenditure and pressure mechanism 9, bypass valve body 3; The be composed of a fixed connection valve body of reverse flow valve of lower valve body 1, upper valve body 2.
Described main valve stem 5, main valve clack 6, bypass valve rod 7, bypass flap 8 are arranged in valve body; Described valve body is provided with valve inlet, valve outlet port, refluxing opening.Described lower valve body 1 connects described bypass valve body 3 at refluxing opening, in bypass valve body 3, has bypass channel; Described expenditure and pressure mechanism 9 is arranged in bypass channel 3, in described expenditure and pressure mechanism 9, is provided with screw channel.
