Abstract
The utility model discloses a water pump bottom valve, which comprises a valve body, a valve bottom and a valve, wherein the valve body is connected with the valve bottom through a flange, a sealing groove is arranged on the valve bottom, a sealing washer is arranged in the sealing groove, and a bulge matched with the sealing groove is arranged on the end surface of the valve body; compare traditional plane farad and add the liner sealed, the utility model discloses a seal groove seals the valve body terminal surface, compresses tightly by the flange again, has strengthened the sealing performance of bottom valve, has reduced the phenomenon of leaking.
Description
Technical field
The utility model relates to a kind of water pump member, relates in particular to a kind of bottom valve of water pump.
Background technique
Existing bottom valve of water pump adopts the face-flange sealing that adds the cushions, and its shortcoming is: after water pump is closed down, because the back of pipeline water pressure is large, the liner of bottom valve junction plane is often gone out valve body by water slug, even valve is thrust, cause that bottom valve seriously leaks, make maintenance become more difficult.
The model utility content
The utility model is intended to provide a kind of good sealing effect, can prevent that bottom valve from leaking, bottom valve of water pump easy to maintenance.
The purpose of this utility model can reach by following measures: 1. bottom valve of water pump, at the bottom of comprising valve body, valve and valve, connect by flange at the bottom of valve body and valve, be provided with seal groove at the bottom of described valve, be provided with seal washer in seal groove, described valve body end face is provided with the projection that coordinates with seal groove.
The technique scheme difference with the prior art is: compare the sealing that adds the cushions of traditional plane farad, the utility model adopts seal groove that the valve body end face is sealed, then by flange screw, has strengthened the sealability of bottom valve, has reduced water leakage phenomenon.
Further, the seal groove degree of depth is 5mm, desirable sealing effect preferably.
The utility model is simple in structure, and is easy to use.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the utility model bottom valve of water pump embodiment's structural representation.
Embodiment
With reference to Fig. 1, a kind of bottom valve of water pump, comprise at the bottom of valve body 1, valve 2 and valve 3, are connected at the bottom of valve body 1 and valve and connect by flange 4, at the bottom of described valve, 2 upper surfaces have seal groove 5, and on the end face of valve body 1, with projection, sealing groove 5 degree of depth are 5mm, be provided with seal washer in seal groove 5, on described valve body 1 end face, projection coordinates with sealing groove 5.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
1. bottom valve of water pump at the bottom of comprising valve body, valve and valve, connects by flange at the bottom of valve body and valve, and it is characterized in that: be provided with seal groove at the bottom of described valve, be provided with seal washer in seal groove, described valve body end face is provided with the projection that coordinates with seal groove.
2. bottom valve of water pump according to claim 1, it is characterized in that: the described seal groove degree of depth is 5mm.
