Embodiment
The embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that this place is retouched
The embodiment stated is merely to illustrate and explain the present invention, and is not intended to limit the invention.
The invention provides a kind of booster pump, the booster pump includes booster pump main body and the end in booster pump main body
Portion's housing 100.The internal structure of end housing 100 and booster pump defines high pressure chest A and low pressure chamber B jointly.End housing 100
Inwall on be formed with the first stop part 1.The pressure relief opening for connecting high pressure chest A and low pressure chamber B is formed with first stop part 1
102.Pressure relief opening can be blocked or open according to the pressure difference value between high pressure chest A and low pressure chamber B by being provided with pressure relief opening 102
102 elastic sealing element 400.
Using the booster pump of the present invention, when the pressure difference value of the water between high pressure chest A and low pressure chamber B is less than critical value,
Elastic sealing element 400 does not deform under the hydraulic pressure effect in high pressure chest A, i.e. the power for causing elastic sealing element 400 to deform is big
In pressure of the water in now high pressure chest A to elastic sealing element 400, thus, elastic sealing element 400 blocks pressure relief opening 102, rises
To 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, the water in high pressure chest A is squeezed
Compression elasticity seal 400 is deformed.A part of water that the deformation of elastic sealing element 400 is opened in pressure relief opening 102, high pressure chest A flows into low
Press chamber B so that the hydraulic pressure reduction in high pressure chest A, the pressure difference value of the water between high pressure chest A and low pressure chamber B is reduced to critical value
Hereinafter, pressure release is completed.As can be seen here, booster pump of the invention matching somebody with somebody by both the first stop part 1 and elastic sealing element 400
Close, it is possible to complete pressure leak process.The present invention booster pump compared with existing booster pump, it is simple in construction, and can effectively solve because
Parts are using excessively, and pressure accumulates the seal and the bad technical problem of pressure stabilization function caused by conduction by parts.
In the specific embodiment of the present invention, as in Figure 2-4, the first stop part 1 is included towards booster pump
Inside extension and endcapped tubular wall 11.In this case, the inside of tubular wall 11 is high pressure chest A, tubular wall 11
Outside be low pressure chamber B.Pressure relief opening 102 can be formed on the side face of tubular wall 11, and elastic sealing element 400 is by being socketed in
State the outside of tubular wall 11 and seal pressure relief opening 102.
In order to ensure elastic sealing element 400 in the presence of hydraulic pressure, it can be deformed along the radial direction of tubular wall 11 to block
Or pressure relief opening 102 is opened, the outer surface of tubular wall 11 is formed with the annular recess 101 that footpath concaves.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, a part of water that the radial deformation of elastic sealing element 400 is opened in pressure relief opening 102, high pressure chest A is flowed by pressure relief opening 102
Enter low pressure chamber B.Preferably, pressure relief opening 102 forms the bottom in 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 be formed between high pressure chest A and low pressure chamber B on transit buffer, the inwall of end housing 100
It is 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 is limited jointly.
In the above-described embodiment, pressure-releasing chamber C-shaped is into the lower section in introduction chamber, and pressure-releasing chamber C top and introduction chamber connect
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 is connected 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, a part of water that the water extruding deformation of elastic sealing element 400 in pressure-releasing chamber C is opened in pressure relief opening 102, pressure-releasing chamber C is flowed into
Low pressure chamber B so that the hydraulic pressure reduction in high pressure chest A.Preferably, one end of the inside for extending to high pressure chest A of the second stop part 2
It is 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 is connected with the bottom of outlet valve 200.Further, booster pump also includes what is be connected with outlet valve 200
Diaphragm 500, diaphragm 500 drives outlet valve 200 to move back and forth from low pressure chamber B to extrude water to high pressure chest A.
In order to ensure booster pump pressurization mesohigh chamber A closed and voltage regulation performance, prevent water excessive from pressure relief opening, bullet
Property seal 400 be 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 when in booster pump pressure leak process, pressure relief opening is opened in rubber turn deformation, flow into the water in high pressure chest A low
Press in chamber B.
Finally, present invention also offers a kind of purifier, the purifier includes above-mentioned booster pump.
The preferred embodiment of the present invention is described in detail above in association with accompanying drawing, still, the present invention is not limited thereto.At this
In the range of the technology design of invention, a variety of simple variants, including each particular technique can be carried out to technical scheme
Feature is combined in any suitable manner.In order to avoid unnecessary repetition, the present invention is to various possible combinations
No longer separately illustrate.But these simple variants and combination should equally be considered as content disclosed in this invention, belong to the present invention
Protection domain.
