It comprises valve body 5, is provided with valve pocket in the valve body, and said valve body left end is provided with water inlet; Said water inlet is communicated with valve pocket through an inlet channel, and said valve body upper end is provided with delivery port 14 and is communicated with valve pocket, and said valve body lower end is provided with pressure relief opening; Be provided with in the said water inlet one with the movable part 3 of water inlet inwall slipper seal; Said movable part middle part is provided with a pressurized hole, is provided with spring A4 between said movable part right-hand member and inlet channel left end, is forming a clearance space under the effect of spring A elastic force between movable part right side and inlet channel left side; Said inlet channel right-hand member is established a plug A6, and said plug A is by spring B 7 elastic top means of press seals inlet channels; During water inlet water inlet state; Because pressurized hole effect movable part left end hydraulic pressure increases and greater than the screen resilience of spring A; Movable part is sealed the inlet channel left side to inlet channel motion and movable part right side, water inlet through after the pressurized hole supercharging through inlet channel and wash plug A open and flow out from delivery port at last; Said movable part right-hand member is communicated with pressure relief opening through exhaust duct with clearance space between the inlet channel left end, and air flows out from pressure relief opening when electromagnetic pump is bled.Said pressure relief opening upper end is communicated with valve pocket through a relief hole, and said relief hole lower end is provided with a plug B10, and said plug B lower end is provided with a spring C11 elasticity roof pressure plug B and blocks relief hole.Said pressure relief opening lower end connects a backwater joint 13, is provided with backwater joint sealing ring 12 between said backwater joint and pressure relief opening lower end.Said movable part be the tube bottom surface to the tubular silica gel spare of inlet channel, said movable part outer tube wall with contact with the slipper seal of water inlet inwall.Said movable part inner tube wall is step-like, and the movable part inner diameter of steel flue is diminished at the bottom of tube by nozzle step by step, and said pressurized hole is a bellmouth.External diameter equates less than the water inlet internal diameter and with inlet channel left end external diameter at the bottom of the said movable part tube, and said spring A left end is socketed at the bottom of the movable part tube, and spring A right-hand member is socketed on the inlet channel left end outer wall.Said valve inleting water mouth connects water supply connector 1; Said water inlet left end excircle is provided with a circle bulge loop; Said water supply connector right-hand member is provided with grab, and said grab is connected on the bulge loop, is provided with water supply connector sealing ring 2 between said water inlet left end inner periphery and water supply connector.Said water inlet left end inwall is provided with a circle annular groove, and said water supply connector right-hand member is provided with a circle flange, and said water supply connector sealing ring is located in the sealing ring that said annular groove and flange surround.Said valve body right-hand member is provided with valve port, and valve port is provided with valve bonnet seal circle 8 by valve gap 9 sealings between said valve gap and valve port.Said valve body is a plastic valve.
Operation principle:
When 1, normally making coffee, the water in the water tank is through electromagnetic pump process water supply connector 1, arrival activity silica gel spare then; Because the pressurized hole of movable silica gel spare is less, the water that receives high pressure through the time, suffered power can be greater than the screen resilience of spring A4; This active rubber spare can be along the motion of the aspect of current; So that the end face of rubber parts can be sealed the end face of valve body 5 inlet channels, and the water of high pressure can be washed plug A6 open, after delivery port gets into boiler.When electromagnetic pump quit work, spring A can be with the resilience of active rubber spare.
2, degassing function: after the water in the coffee machine water tank is drained; Add entry once more and carry out work, start electromagnetic pump, the air in the pipeline can be through water supply connector 1; Then through movable silica gel spare; Because the air pressure in the pipeline is little, can not move by promotion activity silica gel spare, so air can be from flowing out from backwater joint 13 through exhaust duct and pressure relief opening.After air had been arranged, water pump can be extracted into water supply connector 1 to water, then arrival activity silica gel spare; Because the pressurized hole of movable silica gel spare is less, the water that receives high pressure through the time, suffered power can be greater than the screen resilience of spring A4; This active rubber spare can be along the motion of the aspect of current; So that the end face of rubber parts can be sealed the end face of valve body 5 inlet channels, and the water of high pressure can be washed plug A6 open, after delivery port gets into boiler.
3, pressure release function: when pipeline was plugged, after internal pressure surpassed the elastic force of spring C11, hydraulic pressure can be washed plug B10 open, makes the water of high pressure be back to water tank through backwater joint, reaches safe effect.
