Abstract
A three-way valve device of a pressure type coffee maker comprises a valve body, a valve bonnet, a sealing ring, a valve spool and a spring. The sealing ring is sleeved in the valve bonnet and is fittingly fastened with the valve body, and the valve spool and the spring are disposed below the sealing ring. The three-way valve device is characterized by further comprising three channels respectively including a water inlet pipe, a pressure relief pipe and a water outlet pipe, the water inlet pipe is arranged on the valve bonnet and connected with the rear end of a water pump, the pressure relief pipe is disposed below the sealing ring, the water outlet pipe is disposed on the lower portion of the valve body, and communication between the water outlet pipe and the pressure relief pipe is controlled by means of squeezed deformation of the sealing ring. The water pump is started or stopped to control up and down linear movement of the valve spool so as to drive the sealing ring to be closed and opened, and closing and opening of a pressure relief flow return channel are controlled; when coffee is brewed, the water pump is started, and at the moment, negative pressure, which is generated from the water inlet pipe, of the water pump overcomes force of the spring on the lower portion of the sealing ring, so that the pressure relief flow return pipe is sealed; and when the water pump is stopped, the spring at the bottom of the valve spool extends upwards, so that the valve spool is opened, the pressure relief flow return pipe is also opened, and pressure relief is realized.
Description
Technical field
The present invention relates to a kind of coffee machine, specifically is a kind of three-way valve device of pressure-type coffee machine.
Background technology
Along with growth in the living standard, there have been increasing people to use coffee machine.Coffee machine on the existing market all comes pressure release through manual pressure release or the higher magnetic valve of employing cost.Domestic return valve manufacturer very easily produces and refluxes and the unsettled phenomenon of pressure release because of the bad control of its precision, and high because of its required precision, occurs the stuck not pressure release phenomenon of spool easily, and qualification rate is lower; Adopt manual pressure release mode can effectively carry out pressure release at any time, but need control and complex structure manually, cost is higher; If adopt magnetic valve pressure release mode, its cost can promote significantly, reduces its market competitiveness greatly.Therefore, be necessary to do further improvement.
Summary of the invention
The object of the invention aim to provide a kind of simple and reasonable, auto-action, performance safe and reliable, manufacture that cost is low, the three-way valve device of low-cost pressure-type coffee machine, to overcome weak point of the prior art.
Press the three-way valve device of a kind of pressure-type coffee machine of this purpose design; Comprise valve body, valve gap, be sleeved on the spool and the spring that cooperate fastening sealing ring in the valve gap and with valve body, be arranged on the sealing ring below; Its architectural feature is also to comprise three passages; Be arranged on the valve gap respectively and the inlet channel that is connected with the water pump rear end, be arranged on relief pipeline and outlet conduit in the valve body of sealing ring below, through the crimp of sealing ring being controlled the conducting of outlet conduit and relief pipeline.
Be provided with two holes in the said spool, wherein a circular hole is communicated with outlet conduit, and another circular hole is communicated with relief pipeline; The outer wall of two circular holes all is equipped with spring, promotes spool and between sealing ring and valve body, slides up and down.
The top of a said circular hole is provided with diversion division, and the corresponding diversion division of sealing ring is provided with the guiding gutter of a band through hole, is communicated with inlet channel and outlet conduit.
Said spring is opened relief pipeline through the elastic recovery force urges spool jack-up sealing ring that upwards slides.
High pressure current in the said water pump move downward the crush seal circle and compress spring after getting into inlet channel, and sealing ring compresses the sealing relief pipeline and is communicated with outlet conduit.
Whether the present invention controls the upper and lower rectilinear motion of spool and drive sealing ring through starting mode of pump is sealed or opens, thereby controls closing and opening of pressure release return flow line; When infusing coffee, start water pump, the negative pressure that this moment, water pump produced from inlet channel overcomes the dynamics of sealing ring lower springs; Make the sealing of pressure release reflux line, when water pump quit work, spool bottom spring upwards stretched; Open spool, the pressure release reflux line is opened, thus pressure release.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Referring to Fig. 1-Fig. 8, a kind of three-way valve device of pressure-type coffee machine comprises valve body 1, spool 4, spring 3, sealing ring 2, valve gap 5; Be provided with three passages; Be respectively inlet channel 5.1, outlet conduit 1.1, relief pipeline 1.2; Sealing ring 2 is set on the valve gap 5, and sealing ring 2 bottoms are provided with spool 4, is provided with two circular holes in the spool 4; Wherein a circular hole 4.1 is communicated with outlet conduit 1.1, and another circular hole 4.2 is communicated with relief pipeline 1.2; The outer wall of two circular holes all is equipped with spring 3; Be provided with valve body 1 below the spring 3, valve body 1 passes through secure fit with valve gap 5, and spool 4 is under the effect of spring 3; Can be up and down between sealing ring 2 and valve body 1; Intake tunnel 5.1 is arranged at valve gap 5 upper ends, and intake tunnel 5.1 joins with the water pump rear end, and exhalant canal 1.1 joins with beverage making cavity; Sealing ring 2 is provided with a through hole 2.1, is used for inlet channel 5.1 and communicates with outlet conduit 1.1, and when starting mode of pump, the water in the water pump rear end makes sealing ring 2 deformable seal relief pipelines 1.2, gets into brew chamber.When water pump quit work, spring 3 backed down spool 4 and makes sealing ring 2 distortion, thereby relief pipeline 1.2 is opened, and discharges inner waste water.
When coffee machine uses, the first step: power-on heating, the water expanded by heating in heating pot of coffee machine; Produce certain low-pressure in heating pot, the gentle influence that is stressed of water in heating pot gets in the valve body 1 from inlet channel 5.1; This moment, spool 4 backed down sealing ring 2; Open relief pipeline 1.2, promptly relief pipeline 1.2 is in open mode, realizes draining.
Second step: preheating is accomplished; Open water pump, the high pressure current get in the valve body 1 from inlet channel 5.1 through heating pot, and spool 4 is under the effect of high pressure current; Move downward; Thereby make sealing ring 2 move downward sealing relief pipeline 1.2, the high pressure current can only flow out brewing coffee from exhalant canal 1.1.
The 3rd step; Boiled the coffee of required deal, water pump quits work, and the high pressure in heating pot reduces; Spool 4 is moved upward by the driving of the screen resilience of spring 3; Back down sealing ring 2 and relief pipeline 1.2 seals, thereby make relief pipeline 1.2 change open mode into, thereby play pressure release and utilize the hydrocone type principle to reach the effect of backflow pressure release by closed condition.
