Specific embodiment
To make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment
And with reference to attached drawing, the utility model is further described.It should be understood that these descriptions are merely illustrative, and do not really want
Limit the scope of the utility model.In addition, in the following description, the description to known features and technology is omitted, to avoid not
Necessarily obscure the concept of the utility model.
It is appreciated that relief valve provided by the utility model is specifically to apply in capsule coffee machine, to play pressure release
Function, of course it should be noted that the claimed relief valve 100 of the utility model is not limited to apply in capsule coffee
It on machine, can also be applied equally on miscellaneous equipment, with the corresponding function of playing pressure release.
Please refer to Fig.1-Fig. 3, relief valve 100 provided by the utility model, including valve body 10, the work in valve body 10
Plug 20, unidirectional valve support 30, check valve seal head 40 and resetting spring 50.Import 11, first is offered on the valve body 10
Outlet 12 and second outlet 13, wherein the piston 20, unidirectional valve support 30, check valve seal head 40 and resetting spring 50 are set
It puts on the access being connected in import 11 with second outlet 13, to be selected with check valve seal head 40 second outlet 13
Property sealing, and the first outlet 12 is connected respectively with second outlet 13 and import 11, wherein the first outlet 12 with into
The access of mouth 11 is by way of piston 20 and unidirectional valve support 30.In this way it is understood that the second outlet 13 is the relief valve 100
Pressure relief opening, it should be noted that the closure of second outlet 13 realized by check valve seal head 40, so, the pressure release
13 bore of second outlet that valve 100 is specifically used for pressure release may be configured as larger compared with prior art, and then improve the relief valve
Pressure release effect during 100 specific works.
Wherein, the inner wall of the outer wall and valve body 10 of the piston 20 fits, and the piston 20 is towards check valve branch
The side of frame 30 offers a bore and is less than the osculum 21 of 11 bore of import, and be connected with the channel in unidirectional valve support 30.
In practice, the bore of osculum 21 has been opened up into very small on the piston 20, the relief valve 100 of this sample embodiment its into
When mouth 11 is intake, since the flow of osculum 21 is significantly smaller than the flow of inlet water of import 11, so as to not influence needed for import 11
Pressure, can guarantee import 11 pressure energy push piston 20 movement, simultaneously, water can be flow to from the osculum 21 of piston 20
Channel in unidirectional valve support 30.
In the present embodiment, the unidirectional valve support 30 offers the first opening on the side end face towards piston 20
31, multiple second openings 32, and multiple second openings 32 and first are offered on the peripheral wall of the unidirectional valve support 30
Opening 31 connects the channel to collectively form the unidirectional valve support 30.And one end of the unidirectional valve support 30 is to be resisted against piston
On 20, and on the other end it is socket check valve seal head 40.And the resetting spring 50 be arranged on second outlet 13 with it is unidirectional
Between valve support 30.
In this way when the import 11 of valve body 100 is intake, while piston 20 can be moved by the effect of hydraulic pressure, meeting
Unidirectional 30 compression reseting spring 50 of valve support is driven to be moved, until being socketed in the check valve seal head in unidirectional valve support 30
40 block in second outlet 13, thereby realize the closure of second outlet 13, import 11 and the connection of first outlet 12, that is,
The water being discharged by import 11 can go out from first outlet 12；And after water inlet is closed in import 11, hydraulic pressure drives piston 20
Generated active force is less than the produced active force to unidirectional valve support 30 of 50 elasticity recovery deformation of resetting spring, accordingly
Ground, resetting spring 50 can drive unidirectional valve support 30 and piston 20 to be resetted, i.e., second outlet 13 is opened.Since this is let out
Pressure valve 100 is assembled on capsule coffee machine in use, first outlet 12 is connected with hydraulic cavities, and second outlet 13 be with outside
Boundary's atmosphere, that is, the pressure of first outlet 12 is greater than the pressure of second outlet 13, the water being trapped in this way in valve body 10
It will be discharged from second outlet 13, and then realize the decompression function of the relief valve 100.
When there is air in the inside of inner valve body 100, import 11 carries out air inlet, and the gas of entrance can smoothly pass through piston 20
Osculum 21 and unidirectional valve support 30 channel, and come on the access that first outlet 12 is connected with second outlet 13, due to
The pressure of first outlet 12 is greater than the pressure of second outlet 13, and the gas entered in this way by import 11 will directly go out from second
Mouth 13 is discharged outward, is further met the relief valve 100 in this way and is applied the requirement on capsule coffee machine.
In the present embodiment, the valve body 10 is equipped with a connector 60 in a snap-fit manner, and the import of the valve body 10 is
It is arranged on connector 60, the assembling for being convenient for the relief valve 100 whole in this way.Further, the connector 60 is stretching into valve
O-ring 61 is connected on the part of body 10 to seal, the water entered to prevent import 11 leaks.
From the foregoing, it will be observed that the piston 20 is assemblied in valve body 10 in use, will in order to meet the whole use of relief valve 100
It asks, piston 20 can do the movement moved towards 13 direction of second outlet on valve body 10, and the reset of piston 20 is then by multiple
Position spring 50 resets to realize.For this purpose, the relief valve 100 of the present embodiment is it is necessary to set a position limiting structure, to ensure
Piston 20 restores under the action of resetting spring 50 to initial position.Specifically, the relief valve 100 of the present embodiment valve body 10 with
One Piston spacer plates 70 are set at the position between interface 60, and the Piston spacer plates 70 are specifically provided in valve body 10 for assembling
On the step of connector 60, that is, the Piston spacer plates 70 are assembled on the relief valve 100, and position is fixed relative to valve body 10
Constant.Wherein, the through-hole 71 on the Piston spacer plates 70 is set as funnel-shaped structure, and the bore of the through-hole 71 is not less than
The bore of osculum on the piston 20, with ensure from import 11 into water to push the piston 20 to be moved while, can be from work
The osculum 21 of plug 20 flow to the channel of unidirectional valve support 30.Further, the Piston spacer plates 70 are set as integral type with connector 60
Structure is separately set relative to connector 60.
To sum up, the relief valve of the utility model comes the side of selective shut-off second outlet by using check valve seal head
Formula, and resetted using resetting spring, the decompression function of the relief valve is realized, pressure leak process is more quick smooth, i.e.,
The relief valve it is efficient；Meanwhile pass through the structure setting of osculum on piston so that the relief valve at work by hydraulic pressure come
Piston is pushed, and unidirectional valve support and check valve seal head is pushed to block second outlet successively, the stabilization of pressure release
Property is preferable, meets the use demand of capsule coffee machine.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
The spirit of utility model and any modification, equivalent substitution, improvement and etc. within principle, done, should all be included in the utility model
Within the scope of protection.
