Abstract
The utility model discloses a knife type filling valve for a silty river plane gate. The knife type filling valve comprises a suspender with the top hinged to a hanging head of a hoist, a hole groove formed in the middle of the suspender in the longitudinal direction, a bearing shaft which penetrates through the hole groove and is fixedly connected with the plane gate, and a valve plate of a valve chamber arranged between the water inlet of the plane gate and a drainage channel. The upper end of the valve plate is connected with the lower end of the suspender. The lower end surface of the valve plate is of a cutting edge structure inclined upwards towards the downstream side, and the inclination angle a is larger than 30 degrees. The longitudinal section of the suspender is of a U-shaped structure, and a guide wheel matched with a gate groove in a rolling mode is arranged at the portion, below the hole groove, in the suspender of the U-shaped structure. A rubber hermetic seal sealing the surface of the valve plate is arranged in the valve chamber in the mode of surrounding the water inlet. A cantilever type main supporting rail and a lateral guide rail are arranged at the portions, on the two downstream side walls, in the valve chamber respectively. The knife type filling valve has the advantages of being designed for silty rivers to decrease the gate closing force of the plane gate and achieve the purposes of water filling and pressure equalizing of a water-stopping plane gate on the upstream of the silty rivers.
Description
Technical field
The utility model relates to high pressure gate filling valve, especially relates to the cutter type filling valve for fully-loaded stream plane gate.
Background technique
Filling valve is the gate water-filling equipment that particularly high pressure gate is conventional, and the operation of filling valve is generally by pulling unlatching with the suspension rod of guiding groove, relying on deadweight or external force to close.But, for the upstream sealing plane gate using in fully-loaded stream, carry out water-filling concora crush behind the door if adopt the mode of common filling valve, need a larger power of closing, must adopt a large amount of counterweights or corresponding drive unit to operate, due to the existence of silt, valve opening and the reliability of closing are difficult to ensure simultaneously.
Summary of the invention
The utility model object is to provide a kind of cutter type filling valve for fully-loaded stream plane gate.
For achieving the above object, the utility model is taked following technical proposals:
Cutter type filling valve for fully-loaded stream plane gate described in the utility model, comprise that top and hoist hang a hinged suspension rod, longitudinally be opened in the hole slot at described suspension rod middle part, the load-bearing axle being connected with plane gate that runs through described hole slot setting, be arranged on the valve plate of valve chamber between plane gate water intake and dredging flow groove, described valve plate upper end portion is connected with suspension rod lower end; The lower end surface of described valve plate is acclivitous cutting edge structure towards downstream side, and described angle of inclination a is greater than 30 °; The longitudinal section of described suspension rod is U-shaped structure, is positioned at below described hole slot and is provided with and the moving upper saw pulley coordinating of lock trough roller in the suspension rod of described U-shaped structure; In valve chamber, be provided with around water intake the rubber seal sealing sealing mutually with valve plate plate face; In valve chamber, be positioned at two side, downstream and be provided with cantilever type support backbone and beam side rail, after valve installation debugging, hold out against cantilever type and support backbone and beam side rail, ensure the sealing effect of valve plate and rubber seal sealing, then fixing, the support while work as valve plate and guiding.
The utility model advantage is to design for fully-loaded stream, reduces to reach the water-filling concora crush problem that plane gate closes a power, solves fully-loaded stream upstream sealing plane gate.The acclivitous cutting edge structure towards downstream side is arranged in valve plate lower end surface, plays soft material is had to cutting function as weeds etc., and the adhesion on scraped sealing surface, removes the foreign material such as silt automatically simultaneously, has improved the keying ability of plane gate.Described acclivitous blade angle a is arranged to be greater than 30, reaches and improve earial drainage state object.In the suspension rod of described U-shaped structure, be positioned at below described hole slot and be provided with and the moving upper saw pulley coordinating of lock trough roller, ensured weight that suspension rod and hoist hang can vertically act on valve plate on, improved the keying quality of valve plate.Meanwhile, the utility model is simple in structure, easy for installation, can directly utilize hoist to hang head and complete the opening and closing of plane gate and do not need auxiliary drive.
