Description
Technical field
The utility model relates to water pump technology more particularly to a kind of water pumps with one-way valve structures.
Background technique
In the related technology, the structure of water pump is relatively simple, and there is no setting one-way valve structures in water pump.Due to traditional
Water pump lacks one-way valve structures, and after outlet pipe connects water pump, when water pump stops working, the water inside outlet pipe is static
In the case where, in the case where communicating between water pipe and water pump there are atmosphere, water can flow back into the water inlet of water pump from water pipe, lead
Causing water inlet leak or infiltration phenomenon or water occur can lead to leak or infiltration phenomenon occur from the leakage of the water outlet of outlet pipe.
Thus cause existing customer that can connect a split type check valve in the water outlet of water pump when using water pump, but use in this way
Settling mode can improve the product price of client, reduce the competitiveness of product in market.
Utility model content
The main purpose of the utility model is to overcome the deficiencies of above-mentioned background technique, provide a kind of with one-way valve structures
Water pump, avoid water pump occur leak or infiltration the phenomenon that.
Above-mentioned purpose is achieved by the following technical solution:
A kind of water pump with one-way valve structures, including the pump housing, pump cover and one-way valve structures, wherein the pump cover is installed on
On the pump housing, inlet and outlet are formed on the pump cover, the one-way valve structures are set to the water inlet and institute
It states between water outlet, the one-way valve structures include valve body, spool and spring, and the valve body is set on the pump housing, the valve
Core is set on the valve body, and the spring is set between the spool and the roof of the pump cover.
In some embodiments, the one-way valve structures further include having valve seals, and the valve seals are set to
Between the valve body and the roof of the pump cover.
In some embodiments, the one-way valve structures further include having valve core seal ring, and the valve core seal ring is set to
Between the spool and the valve body.
In some embodiments, cylindrical protrusion, the lower spring end are provided among the top surface of the spool
It is sheathed on outside the protrusion and the bottom surface of the spring is against on the top surface of the spool.
In some embodiments, sunk area is provided among the bottom of the pump cover, the valve body is set to described
In sunk area.
In some embodiments, it is provided between the sunk area and the water outlet and is connected to interface, the valve
Core is set in the connection interface.
The utility model compared with prior art, at least has the effect that
A kind of water pump with one-way valve structures of the utility model, due to being provided with one-way valve structures in pump body,
Thus it may make and water pump avoided the phenomenon that leak or infiltration occur.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of water pump in embodiment；
Fig. 2 is the decomposition diagram of water pump in embodiment；
Fig. 3 is the structure sectional view of water pump in embodiment.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Embodiment 1: as shown in Figure 1, Figure 2 and Figure 3, the present embodiment provides a kind of water pump with one-way valve structures, packets
The pump housing 1, pump cover 2 and one-way valve structures are included, wherein the pump cover 2 is installed on the pump housing 1, are formed on the pump cover 2
Water inlet 201 and water outlet 202, the one-way valve structures are set between the water inlet 201 and the water outlet 202, described
One-way valve structures include valve body 3, spool 4 and spring 5, and the valve body 3 is set on the pump housing 1, and the spool 4 is set to the valve
On body 3, the spring 5 is set between the spool 4 and the roof of the pump cover 2.
A kind of water pump with one-way valve structures of the present embodiment, due to being provided with one-way valve structures in pump body, by
This, which may make, avoids water pump from the phenomenon that leak or infiltration occur.
The working principle of the present embodiment check valve is briefly described below:
The upward water of spring is flowed out from spool edge after when pump working, spool is under pressure, the spool when water air pump inoperative
In the case where no pressure, spring is pressed down against type into seal cavity, and outlet pipe is caused to disconnect the state that atmosphere communicates with water pump, from
And avoid the leak of water pump, infiltration phenomenon.
Further, the one-way valve structures further include having valve seals 6, and the valve seals 6 are set to the valve
Between body 3 and the roof of the pump cover 2, structure is simple, and the leakproofness between valve body 3 and pump cover 2 can be improved, avoid in valve body
There is the case where leak between 3 and pump cover 2.
Further, the one-way valve structures further include having valve core seal ring 7, and the valve core seal ring 7 is set to the valve
Between core 4 and the valve body 3, structure is simple, and design rationally, can be improved the leakproofness between valve body 3 and spool 4, avoid
There is the case where leak between valve body 3 and spool 4.
Preferably, cylindrical protrusion 400 is provided among the top surface of the spool 4,5 lower end of spring is sheathed on
The bottom surface of the described raised 400 outer and described springs 5 is against on the top surface of the spool 4, and structure is simple, can effectively avoid bullet
