Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment who obtains under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1
As shown in Figure 1, a kind of Decompression valves of the present invention, Decompression valves is for coffee machine, comprise valve body 1, valve gap 2, spool 3, backstop 4 and decompression cover 5, valve inner is provided with cavity 9 for water route circulation, for the water inlet 10 that is connected with coffee machine water route, for the first water outlet 11 of being communicated with coffee maker brew chamber respectively and the second water outlet 12, for the pressure relief opening 13 of pressure release, valve gap 2 is arranged on valve body 1 upper end, decompression cover 5 is arranged on pressure relief opening 13, backstop 4 is arranged on the first water outlet 11, spool 3 is arranged in cavity 9, and moves along cavity 9.Spool 3 is provided with the seal ring 6 for sealing between spool 3 and the cavity 9 of valve body 1.Valve gap 2 is provided with the seal element 8 for sealing with seal element 7, decompression cover 5 that valve body 1 joint is provided with for sealing with pressure relief opening 13 joints of valve body 1.In the present embodiment, seal ring 6 is 0 RunddichtringO; Seal element 7,8 is y-type seal ring, adopts Y type rubber coil structures, because of its distinctive characteristic, realizes low friction, the function of high sealing.Spool 3, because of its all structure, has made up the defect of associated electrical series products, contains partial impurities and also can not be affected in the water that toilet is let out.
Working principle: as shown in Figure 1, now Decompression valves is in the normal state, coffee brewing cavity is connected with the outlet of decompression cover 5.The cavity 9 of valve body 1, by spool 3, has been divided into upper and lower two spaces, and upper space is because of backstop 4 and 14 isolation of coffee brewing chamber.The top of spool 3 in whole Decompression valves group.When coffee machine carries out brewing coffee, water enters Decompression valves inside through Decompression valves water inlet 10, after the upper space of the full Decompression valves cavity 9 of water punching, and the pressure rise in valve body, when pressure reaches one regularly, spool 3 is promoted downwards by pressure.
As shown in Figure 2, when shifting certain position onto, spool 3 stops action.Cavity 9 internal pressures continue to rise, when pressure is greater than the pressure that backstop 4 sets, backstop is opened, form conducting, water is entered in coffee powder brewing chamber and is carried out brewing coffee by the first water outlet 11, now spool 3 is sealing state with seal element 8, so water can not flow out from pressure relief opening 13.
As shown in Figure 1, after coffee brewing completes, machine quits work, and after the water route pressure of Decompression valves cavity 9 upper spaces is released, backstop 4 is got back to original state, and water route is closed.And now the pressure in the lower space of Decompression valves cavity 9 will be greater than the pressure in the upper space of Decompression valves cavity cavity 9, now spool 3 is because pressure difference starts to move upward.When spool 3 rises to certain position, seal element 8 departs from spool 3, the upper space of Decompression valves cavity 9 is connected with the outlet of decompression cover 5, and the pressure in the upper space of Decompression valves cavity 9 discharges from the outlet port of decompression cover 5, and now spool 3 stops moving upward and gets back to original state.
Embodiment 2
All the other are identical with embodiment 1, and difference is, seal ring 6 is y-type seal ring.According to different work requirements, seal ring 6 is 0 RunddichtringO, V-shaped seal ring or y-type seal ring.
All the other are identical with embodiment 1, and difference is, seal element 7,8 is O RunddichtringO.According to different work requirements, seal element 7,8 is y-type seal ring, V-shaped seal ring or O RunddichtringO.
Adopt the beneficial effect of the technical program to be: simple and reasonable, safety rate is high, reliable performance, with respect to the product of congenerous, has greatly reduced cost and space.Coordinate driving element applied thrust on spool, make it in course of action, produce differential pressure, thereby realize the function that discharges body water route internal pressure.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the present invention.To these embodiments' multiple modification, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
