Abstract
The utility model relates to flap valves at a water outlet of a water pump, in particular to a novel traction disengaging resistant type flap valve, and belongs to the technical field of water supplying and water drainage projects. According to the new technical scheme, the novel traction disengaging resistant type flap valve solves the technical problem that a flap valve cover easily disengages and drifts away. The novel traction disengaging resistant type flap valve comprises a base, hinged supports, a hinge pin and the flap valve cover, wherein the flap valve cover and the base are hinged to the hinge pin through the hinged supports, the flap valve cover is further provided with a traction ring, and the traction ring is connected with a fixed support through a steel wire rope. The fixed support can be arranged inside a concrete body at the top of a structure in an embedded mode, so that the fixed support is firm. Due to the fact that the traction ring is arranged at the upper end of the central axis of the flap valve cover, water pressure borne by the flap valve can be conveniently reduced when the flap valve is repaired and lifted up, and lifting working is facilitated. According to the novel traction disengaging resistant type flap valve, the flap valve cover can be effectively prevented from drifting into an underground box culvert along with water flow, therefore the box culvert is prevented from being blocked, and the flap valve cover can be conveniently taken out and repaired.
Description
Technical field
The utility model relates to a kind of flap valve of pump outlet, and especially a kind of novel traction loose-prevention type flap valve belongs to the water supply and sewage work technical field, can be applicable to the pumping line end of pumping plant.
Background technique
Flap valve is mounted in a kind of one-way valve at supply and drain water system pipe water outlet place, is the on-off action of realizing the flap valve lid by the pressure difference of the inside and outside both sides of flap valve lid, and its effect is 1. to prevent that the aqueous reflux of high water level is to the water inlet pool of low water level; 2. prevent that water pump from reversing infringement equipment under the effect of refluence water.
At present, the flap valve of sewage pump station water outlet adopts mostly is the flap valve lid and the flap valve base is by the hinge Placement, and it is subjected to the turn on pump impact grinding for a long time and undermines the sewage immersion corrosion and cause flap valve to cover easily coming off.And the flap valve after coming off lid is because its special the rim of a bowl shape, after being subjected to big current frequent impact, can cause the flap valve lid to waft in the underground box culvert with current, not only is difficult to take out maintenance, also can stop up box culvert, causes serious draining accident.
Summary of the invention
For solving the technical problem that the flap valve lid comes off easily and wafts, prevent to cause flap valve lid to waft in the underground box culvert with current, and the obstruction box culvert, and be convenient to take out maintenance, the utility model provides a kind of towed flap valve, comprises base, free bearing, bearing pin, flap valve lid, and described flap valve lid is hinged by free bearing and bearing pin with base, this flap valve covers and also is provided with draw ring, and draw ring is connected with fixed support by wire rope.
Further, fixed support is implanted in the concrete body of structure top, makes fixed support very firm.
Further, draw ring is arranged on the upper end of flap valve lid medial axis, is convenient to reduce its suffered hydraulic pressure when maintenance lifting flap valve, is beneficial to lifting operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an embodiment's of the utility model a schematic representation.
Reference character:
1. flap valve covers, 2. free bearing, 3. bearing pin, 4. draw ring, 5. wire rope, 6. fixed support, 7. base.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of towed flap valve of the present utility model comprises flap valve lid 1, free bearing 2, bearing pin 3, draw ring 4, wire rope 5, fixed support 6, base 7, described flap valve lid 1 is hinged by free bearing 2 and bearing pin 3 with base 7, and described flap valve lid 1 is provided with described draw ring 4, it is connected with fixed support 6 by described wire rope 5, described fixed support 6 is implanted in the concrete body of structure top securely, and described draw ring 4 is arranged on described flap valve and covers 1 medial axis and hold on the upper side, and suffered hydraulic pressure is to its resistance in the time of can reducing to lift by crane the maintenance flap valve.
The utility model is installed on the pumping line end, can open and close automatically, in daily production process, also can judge whether flap valve comes off by described wire rope 5 level of tightness, in case and flap valve hinge partial corrosion, damage and to come off, after the maintenance of flap valve can being sling is finished, the installation of cutting off the water again can reduce the off-time.
