The pressure release valve has good sealing effect and flexible installation, and can timely discharge air at the front end of the electromagnetic pump, thereby achieving the self-absorption effect and avoiding that the electromagnetic pump can not pump water.
Description
Technical field
The utility model relates to a kind of relief valve, particularly a kind of relief valve that is used for coffee machine.
Background technology
The relief valve that uses in the coffee machine at present mainly is after coffee brewing is accomplished, to let out except that pressure for whole brewing system, receives the electromagnetic pump outlet usually, and then is connected on the heater, is connected to brewing cavity through heater.The pressure-relief valve structure that existing coffee machine is used all includes water inlet, delivery port, discharge opening; Between water inlet and discharge opening, be provided with valve plug; Sealing gasket between valve plug and pressure relief opening adopts O shape circle or round rubber head mostly, and this structure often needs very big pressure that valve plug is closely contacted with valve pad, and then reaches the effect of sealing; Tend to cause the discharge opening sealing unreliable waste water resource as on the low pressure machine, using because pressure is less.Simultaneously, when relief valve was in off position, valve plug can be blocked the water inlet that communicates with electromagnetic pump, can make the electromagnetic pump water side be in sealing state like this, had influenced the self-priming effect of electromagnetic pump.
Summary of the invention
The technical problem that the utility model will solve provides a kind of simple in structure, reliable, self-relieving coffee machine relief valve of sealing.The utility model can use on the coffee machine of any pressure, no matter is that low pressure or high pressure can both operate as normal, and can both reaches good sealing effectiveness.
In order to solve the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of relief valve that is used for coffee machine; Comprise valve body and place the valve gap on the valve body, the valve gap of telling is provided with inlet, and said valve body is provided with valve pocket and is communicated with the pressure relief opening and the outlet of valve pocket; At valve inner; Be provided with the channel connection or the disconnected valve plug that can make between inlet and the pressure relief opening between inlet and the pressure relief opening, the pressure relief opening position is provided with the sealing gasket that can closely contact with valve plug, and said sealing gasket is the annulus column that give prominence at the middle part.
Be provided with connection sealing gasket and valve plug on sealing gasket top and can make valve plug to the elastomeric element that moves away from the pressure relief opening direction.Described elastomeric element is a spring.
Said valve plug is inner small and outside big step structure.
The sealing gasket of the utility model has been owing to adopted the outstanding annulus column construction in middle part, closely contacts more easily between valve body and the valve gap, reaches better sealing effectiveness, thereby practiced thrift water resource.Elastomeric element on the sealing gasket can make valve plug reset flexibly; And, not only improved the degree flexible for installation of relief valve no matter whether its installation site must be vertical with mode, can also easily get rid of the electromagnetic pump front end air; Thereby reach the effect of self-priming, avoid electromagnetic pump not take out water.
Description of drawings
Fig. 1 is a relief valve opening sketch map;
Fig. 2 is the relief valve working state schematic representation;
Fig. 3 is sealing gasket and valve plug three-dimensional structure diagram.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.
Relief valve shown in Fig. 1, Fig. 2 comprises valve body 1 and the valve gap 2 that is assembled together through manner and valve body 1; Valve gap 2 is provided with the inlet 21 that links to each other with electromagnetic pump; Valve body 1 is provided with valve pocket 13 and is communicated with the pressure relief opening 12 and outlet 11 of valve pocket 13; Its middle outlet 11 heater vias are connected to brewing cavity, and pressure relief opening 12 links to each other with extraneous waste water box.Be provided with valve plug 3 between valve body 1 inside, inlet 21 and the pressure relief opening 12, pressure relief opening 12 positions are provided with the outstanding annulus cylindricality sealing gasket 5 in middle part.
A preferred version as the utility model; Be with elastomeric element on sealing gasket 5 tops; This elastomeric element 4 connects sealing gaskets 5 and valve plugs 3, and valve plug 3 is axially moved under the effect of elastomeric element 4, so make enter the mouth 21 with pressure relief opening 12 between channel connection or be not communicated with.Certainly, the elastomeric element 4 in this programme can be a spring, also can be other any parts with spring performance.
As another preferred version of the utility model, said valve plug 3 is inner small and outside big step structure, and valve plug 3 moves and crush seal pad 5 to sealing gasket 5 directions in the time of sealing, thereby reaches sealing purpose.
Fig. 1 is a relief valve opening sketch map, and water is got in the valves by inlet 21 when electromagnetic pump is started working, and gets into brewing cavity and waste water box from exporting 11 respectively with pressure relief opening 12.The electromagnetic pump continuous firing; In brewing cavity, begin to produce pressure; The elastic force that valve plug 3 will overcome spring 4 under the liquid pressure effect when pressure increases to preset pressure moves to outlet 12 directions; Thereby final valve plug 3 is closed outlet 12 by compressing tightly at sealing gasket 5 under the liquid pressure that constantly increases, water can only flow to outlet 11, then gets into brewing cavity.As shown in Figure 3, because sealing gasket 5 adopts softer elastomeric material to make, its profile is designed to the outstanding annulus column construction in middle part; The sealing gasket 5 of this structure is easy to open, and contacts and the step structure of valve plug 3 makes sealing gasket 5 and valve plug 3 be linear, and contact area is little; It is little to rub, sealing more easily, and also very little power just can reach the better seal effect; Therefore, even using, the utility model also can reach same sealing effectiveness on the low pressure machine.
Fig. 2 is the relief valve working state schematic representation, and when electromagnetic pump quit work, the pressure of brewing system will descend rapidly.When pressure dropped to preset pressure, valve plug 3 was separated with sealing gasket 5 under the effect of spring 4, and simultaneously, sealing gasket 5 can shrink, and the help valve plug resets, thereby pressure relief opening 12 is opened.Export 11 this moment, pressure relief opening 12 all will open, heater, brewing cavity, electromagnetic pump all communicate with the external world, are under the state of 0Bar pressure.So, even the heater heating can not produce pressure yet in pipeline; The pressure of brewing cavity also can be let out from pressure relief opening 12 fast and remove; The front end of electromagnetic pump so be easy to self-priming, can not occur not taking out the phenomenon of water owing to be under the state of 0Bar pressure.
More than be merely a specific embodiment of the utility model, but the design concept of the utility model is not limited thereto, all insubstantial modifications of utilizing this design that the utility model is made all fall within the protection domain of the utility model.
