Abstract
The invention provides a novel check valve. The novel check valve comprises a check valve body, a check valve rod, a check valve seat, a check valve disc and a check valve bush, wherein a plurality of folded plates evenly distributed around the check valve rod are arranged on the upper surface of the check valve disc, one side of each folded plate is hinged to the check valve disc, a plurality of baffles are arranged on the check valve bush, each baffle corresponds to one folded plate, and the distance between the outer edge of each baffle and the check valve rod is larger than the distance between the hinging side of each folded plate and the check valve rod; when a water pump is started, water impacts upwards to enable the folded plates to be folded upwards along the hinging sides to make contact with the baffles, and when the water pump is stopped, the folded plates recover to be horizontally arranged on the upper surface of the check valve disc. The novel check valve has the advantage that while downward decreasing resistance is generated on a water outlet the moment when the pump is stopped, resistance on water flow during normal operation of the water pump is reduced.
Description
Technical field
The present invention relates to a kind of new type check valve.
Background technique
Pump is in the process of installing, and the end of the pump housing generally all can install a circular check valve (see Fig. 1), and the power produced by the water outlet in a flash running to stopping at pump is offset in the effect of check valve, prevents from damaging water pump vane blade.The check valve of legacy forms certain resistance when water pump runs well to current, and the check valve body wall of legacy is thinner in addition, in the process used, be easy to fracture, if fracture, the whole pump housing of water pump all can be fallen in well.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of new type check valve, overcomes the deficiencies in the prior art.
For solving the problems of the technologies described above, the technical solution used in the present invention is: new type check valve, comprise check valve case, check valve rod, check valve seat, check valve disc and check valve pocket, described check valve pocket is fixed on described check valve disc, described check valve pocket is placed on described check stem lower portion, described check valve seat is fixed in described check valve case, described check valve cover for seat is outside described check valve pocket, the upper surface of described check valve disc has multiple multiple flaps uniform around described check valve rod, described flap is while hinged with described check valve disc, the opposite side edge of described flap stretches out described check valve web edge, described check valve puts has multiple baffle plate, the corresponding described flap of each described baffle plate, described baffle plate outer is greater than the distance of the hinged edge of described flap apart from described check valve rod apart from the distance of described check valve rod,
When starting mode of pump, current direction impacts and described flap is upwards turned up along its hinged edge contact with described baffle plate to described flap, when water pump stops, described flap returns to level and is placed on the upper surface of described check valve disc;
Described check valve case is cylindrical housings.
Further, also comprise two U-shaped reinforcement covers, described U-shaped reinforcement cover lays respectively at described check valve case both sides, the described U-shaped upper and lower flanging strengthening cover respectively with the upper and lower surface contact of described check valve case, described upper and lower flanging has the bolt hole passed for bolt.
Further, described U-shaped reinforcement cover is made up of steel plate.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, and can not cause resistance to current while the effect of normal performance check valve, check valve case structure strengthens can not breaking releasing.

Embodiment
As shown in Figure 2,3, a kind of new type check valve, comprise check valve case 17, check valve rod 22, check valve seat 21, check valve disc 23 and check valve pocket 24, check valve pocket 24 is fixed on check valve disc 23, check valve pocket 24 is placed on check valve rod 22 bottom, check valve seat 21 is fixed in check valve case 17, and check valve seat 21 is placed on check valve pocket 24 outer (above structure is prior art).Improvement of the present invention is: the upper surface of check valve disc 23 has multiple multiple flaps 36 uniform around check valve rod 22, flap 36 is while hinged with check valve disc 23, the opposite side edge of flap 36 stretches out check valve disc 23 edge, check valve pocket 24 has multiple baffle plate 35, the corresponding flap 36 of each baffle plate 35, baffle plate 35 outer is greater than the distance of the hinged edge of flap 36 far from check valve rod 22 apart from the distance of check valve rod 22;
When starting mode of pump, current direction impacts and flap 36 is upwards turned up along its hinged edge to flap 36 contact with baffle plate 35, now due to flap 36 by water impact to turning up state, therefore when water pump normally runs, the resistance of check valve disc 23 pairs of current reduces greatly, so namely improves the working efficiency of water pump to a certain extent;
When water pump stops, flap 36 returns to level and is placed on the upper surface of check valve disc 23, and now due to the existence of flap 36, the entire area of check valve disc 23 increases, the resistance alleviated downwards to water outlet is also larger, and so namely more effective preventing damages water pump vane blade.
Check valve case 17 is cylindrical housings, adds relative to check valve case 17 thickness of the prior art, makes the intensity of whole check valve case 17 be strengthened like this
Further, also comprise two U-shaped reinforcement covers 33, U-shaped reinforcement cover 33 lays respectively at check valve case 17 both sides, the upper and lower flanging of U-shaped reinforcement cover 33 respectively with the upper and lower surface contact of check valve case 17, upper and lower flanging has the bolt hole 34 passed for bolt.U-shaped reinforcement cover 33 is made up of steel plate.U-shaped reinforcement cover 33 further enhances the structural strength of check valve case 17, ensure that check valve case 17 can not in use rupture.
Above embodiments of the invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
