Description
Technical field
The utility model relates to a kind of accessory of irrigation and drainage pumping station, is specifically the flap valve that a kind of water pump that is applied to irrigation and drainage pumping station dams when shutting down.
Background technique
The water pump of irrigation and drainage pumping station will prevent that the water that is discharged to water outlet pool from flowing back to water inlet pool by outlet pipe when shutting down, and prevent from flowing backwards, is generally to realize by flap valve.Side-turning type flap valve is generally that upper and lower hinge arrangement is angled at present, and upper and lower hinge is not on same vertical line; The outlet of gate seat is also made to certain angle of inclination, i.e. outlet not on same vertical line, so just can be leaned on a component automatic door-closing of door leaf deadweight up and down simultaneously.But this rollover flap valve has following shortcoming: 1, the hinge up and down of flap valve is not on same vertical line, and the frictional force overcoming while opening the door is larger, and the hydraulic loss that this has just increased pumping plant unit, has reduced unit efficiency, has wasted electric energy.Meanwhile, in order to guarantee the coaxality of upper and lower hinge, in the process of producing, also strengthen the difficulty of making, expended more man-hour, increased the cost of production of flap valve.2, flap valve is to realize automatic door-closing by a component of door leaf deadweight, and this is less than 90 degree with regard to having determined the opening angle of flap valve, and angle is uncontrollable after reserving.Because this structure allows water obtain in outlet port first, shrink and spread, this has just affected the fluidised form of water when outlet, has increased the hydraulic loss of pumping plant unit, has reduced unit efficiency, has wasted electric energy.What 3, between the gate seat of flap valve and door leaf, adopt is y-type seal ring sealing or the sealing of solid O type circle, easily there is in actual use turnover phenomenon in y-type seal ring, cause seal failure, there is local water leakage phenomenon, solid O type circle decrement is little, add the distortion of door leaf flange production process, in actual applications, also occur local water leakage phenomenon.4, the complicated integral structure of flap valve, Heavy Weight, cost compare is high, is not suitable for large-scale popularization application.
