Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.
The utility model provides a kind of booster pump, and the booster pump includes booster pump main body and in booster pump main body
End housing 100.The internal structure of end housing 100 and booster pump defines high pressure chest A and low pressure chamber B jointly.End shell
Formed with the first stop part 1 on the inwall of body 100.Formed with for connecting high pressure chest A's and low pressure chamber B on first stop part 1
Pressure relief opening 102.Being provided with pressure relief opening 102 can block or open according to the pressure difference value between high pressure chest A and low pressure chamber B
The elastic sealing element 400 of pressure relief opening 102.
Using booster pump of the present utility model, when the pressure difference value of the water between high pressure chest A and low pressure chamber B is less than critical value
When, elastic sealing element 400 does not deform under the hydraulic pressure effect in high pressure chest A, i.e. causes what elastic sealing element 400 deformed
Power is more than now the water in high pressure chest A is to the pressure of elastic sealing element 400, and thus, elastic sealing element 400 blocks pressure relief opening
102, play pressure stabilization function.And when the pressure difference value of the water between high pressure chest A and low pressure chamber B is more than critical value, in high pressure chest A
Water extruding elastic sealing element 400 deform.Elastic sealing element 400, which deforms, opens pressure relief opening 102, a part of water in high pressure chest A
Flow into low pressure chamber B so that the hydraulic pressure in high pressure chest A is reduced, and the pressure difference value of the water between high pressure chest A and low pressure chamber B is reduced to
Below critical value, pressure release is completed.As can be seen here, booster pump of the present utility model passes through the first stop part 1 and elastic sealing element 400
Both cooperations, it is possible to complete pressure leak process.Booster pump of the present utility model is simple in construction compared with existing booster pump, and
Can effectively solve because parts are using excessively, pressure is bad by the seal caused by parts accumulation conduction and pressure stabilization function
Technical problem.
In a specific embodiment of the present utility model, as in Figure 2-4, the first stop part 1 is included towards increasing
The inside extension of press pump and the tubular wall 11 of endcapped.In this case, the inside of tubular wall 11 is high pressure chest A, tubulose
The outside of wall 11 is low pressure chamber B.Pressure relief opening 102 can be formed on the side face of tubular wall 11, and elastic sealing element 400 passes through socket
Pressure relief opening 102 is sealed in the outside of the tubular wall 11.
In order to ensure elastic sealing element 400 in the presence of hydraulic pressure, can be deformed along the radial direction of tubular wall 11 to block
Or pressure relief opening 102 is opened, the annular recess 101 that the outer surface of tubular wall 11 concaves formed with footpath.Pressure relief opening 102 is formed in pipe
On shape wall 11 and connect the inside of annular recess 101 and tubular wall 11.Elastic sealing element 400 is arranged in annular recess 101.
In this case, annular recess 101 plays axial limiting effect to elastic sealing element 400, i.e. annular recess 101 can be effective
Prevent axial movement of the elastic sealing element 400 along tubular wall 11 under hydraulic pressure effect.When the water in high pressure chest A extrudes elastic packing
During part 400, the radial deformation of elastic sealing element 400 opens pressure relief opening 102, and a part of water in high pressure chest A is flowed by pressure relief opening 102
Enter low pressure chamber B.Preferably, pressure relief opening 102 is formed in the bottom of the upper annular groove 101 of tubular wall 11.Pressure relief opening 102 can be one
It is individual or along the circumferentially distributed multiple through holes of tubular wall 11.
Further, in order to form transit buffer between high pressure chest A and low pressure chamber B, on the inwall of end housing 100
Formed with for high pressure chest A to be divided into introduction chamber and pressure-releasing chamber C the second stop part 2.Pressure-releasing chamber C one end connects with introduction chamber
It is logical, separated between pressure-releasing chamber the C other end and low pressure chamber B by the first stop part 1.Preferably, the first stop part 1 can be formed
For from end housing 100 towards high pressure chest A inside in the first direction, for example, Longitudinal extending.Second stop part 2 can be formed as
From end housing 100 towards high pressure chest A inside in a second direction, for example, extending laterally.Pressure-releasing chamber C is by the first stop part 1, end
The stop part 2 of portion's housing 100 and second limits jointly.
In the above-described embodiment, pressure-releasing chamber C-shaped connects into top and the introduction chamber in the lower section of introduction chamber, pressure-releasing chamber C
It is logical, separated between pressure-releasing chamber C right side and low pressure chamber B by the first stop part 1.Because pressure-releasing chamber C connects with introduction chamber, pressure release
Hydraulic pressure in chamber C is equal with the hydraulic pressure in high pressure chest A, when the pressure difference value of the water between high pressure chest A and low pressure chamber B is more than critical
During value, the water extruding elastic sealing element 400 in pressure-releasing chamber C, which deforms, opens pressure relief opening 102, and a part of water in pressure-releasing chamber C flows into
Low pressure chamber B so that the hydraulic pressure in high pressure chest A reduces.Preferably, one end of the inside for extending to high pressure chest A of the second stop part 2
Formed with the guide portion 21 bent downwards.Guide portion 21 is used to the water in introduction chamber being drained in pressure-releasing chamber C.
In addition, booster pump includes the intermediate plate 300 that is fastened and connected with end housing 100 and set through intermediate plate 300
Outlet valve 200, high pressure chest A connect with the bottom of outlet valve 200.Further, booster pump also includes what is be connected with outlet valve 200
Diaphragm 500, diaphragm 500 drive outlet valve 200 to move back and forth so that water is extruded to high pressure chest A from low pressure chamber B.
In order to ensure booster pump pressurization mesohigh chamber A closed and voltage regulation performance, prevent that water is excessive from pressure relief opening, bullet
Property seal 400 is rubber turn.The sealing force of rubber turn, i.e. non-deformability, should be greater than booster pump pressurization
Hydraulic pressure in mesohigh chamber A.In this case, when in booster pump pressurization, rubber turn is indeformable play it is closed and
Pressure stabilization function, and pressure relief opening is opened when in booster pump pressure leak process, rubber turn deforms, flow into the water in high pressure chest A low
Press in chamber B.
Finally, the utility model additionally provides a kind of purifier, and the purifier includes above-mentioned booster pump.
Preferred embodiment of the present utility model, still, the utility model and unlimited is described in detail above in association with accompanying drawing
In this.In range of the technology design of the present utility model, a variety of simple variants can be carried out to the technical solution of the utility model,
It is combined in any suitable manner including each particular technique feature.In order to avoid unnecessary repetition, the utility model
Various combinations of possible ways are no longer separately illustrated.But these simple variants and combination should equally be considered as the utility model institute
Disclosure, belong to the scope of protection of the utility model.
