Description
Technical field:
The utility model relates to a kind of relief valve, particularly relates to a kind of pressure-relief valve structure of pressure coffee machine.
Background technology:
Existing coffee machine adopts the hydraulic pressure principle to extract coffee when making coffee usually, all needs to carry out pressure release after having boiled coffee, can again load new ground coffee or coffee capsule boils lower a cup of Java.Pressure release mainly is to eliminate to have boiled the pressure in the coffee machine after the coffee.Its basic principle is that the pipeline with coffee machine switches, and the somewhere of coffee machine pipeline is communicated with atmosphere, reaches pressure release.Traditional way is to adopt manual pressure release to realize this process of pressure release, and manually the pressure release meeting increases operator's action frequency, operates comparatively loaded down with trivial details.So existing coffee machine all adopts the magnetic valve pressure release usually, still, the cost of magnetic valve is high, in addition again power consumption, the less stable of pressure release.Therefore, be necessary to be improved.
The utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provides that a kind of operation is very easy and cost is low, the pressure-relief valve structure of the good stability of pressure release, safe coffee machine.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of pressure-relief valve structure of pressure coffee machine, comprise valve body, described valve body is provided with water inlet, delivery port and pressure relief opening, described valve inner is provided with and described water inlet, the pipeline that delivery port and pressure relief opening are communicated with, described valve inner is provided with the pressure release valve pocket with described pipeline connection, also be provided with the small pressure relief opening that communicates all the time with extraneous and described pressure release valve pocket on the described valve body, being provided with in the described pressure release valve pocket can axially movable piston, be provided with back-moving spring between described piston and the described valve body, but be provided with the unidirectional spool of folding in the described piston, the two ends of described spool communicate with described water inlet and delivery port respectively, when described water inlet water filling, be subjected to the resistance of described spool, described piston moves axially thereupon and seals described pressure relief opening, at this moment, described delivery port and pressure relief opening do not communicate, and described piston continues to move to that stopped by spacing control mobile, makes the pressure of described water inlet continue to increase and open described spool, at this moment, described water inlet and delivery port communicate.
The flow of described small pressure relief opening water outlet pressure release is significantly smaller than the flow of inlet water of described water inlet, and is in all the time in the course of the work the pressure release state.
When the coffee machine pipeline occur to stop up and makes described water outlet when pressure anomaly increases, described piston moves axially towards the direction of described water inlet, and described delivery port and pressure relief opening are communicated.
The utility model has following advantage with respect to prior art:
The utility model can automatically be eliminated and boil the pressure in the coffee machine after the coffee, and no longer need any extra operation, not only easy to use, simple in structure, and the cost of saving coffee machine, be provided with the small pressure relief opening that communicates all the time with extraneous and pressure release valve pocket at valve body in addition, so that pressure release is more smooth and easy, effectively improved security and the service life of coffee machine.
Description of drawings:
Fig. 1 is cutaway view of the present utility model.
The specific embodiment:
With reference to shown in Figure 1, the pressure-relief valve structure of a kind of pressure coffee machine that provides according to the utility model, comprise valve body 1, this valve body 1 is provided with water inlet 2, delivery port 3 and pressure relief opening 4, valve body 1 inside is provided with and water inlet 2, the pipeline that delivery port 3 and pressure relief opening 4 are communicated with, valve body 1 inside also is provided with the pressure release valve pocket with pipeline connection, valve body 1 is provided with the small pressure relief opening 5 that communicates all the time with extraneous and pressure release valve pocket, being provided with in the pressure release valve pocket can axially movable piston 6, be provided with back-moving spring 7 between this piston 6 and the valve body 1, but be provided with the unidirectional spool 8 of folding in the piston 6, the two ends of this spool 8 communicate with water inlet 2 and delivery port 3 respectively.When water inlet 2 water filling, be subjected to the resistance of spool 8, piston 6 moves axially thereupon and seals pressure relief opening 4, at this moment, delivery port 3 and pressure relief opening 4 do not communicate, and piston 6 continues to move to that stopped by spacing control mobile, make the pressure at water inlet 2 places continue increase and open spool 8, at this moment, water inlet 2 and delivery port 3 communicate, and reach the requirement of making coffee; When water inlet 2 stops water filling, be subjected to the pressure release of small pressure relief opening 5 and the effect of back-moving spring 7 and pressure that delivery port 3 keeps, piston 6 is return and is opened pressure relief opening 4 thereupon moving axially, at this moment, delivery port 3 and pressure relief opening 4 communicate, and reach the pressure release requirement of coffee machine.
In the installation of pressure coffee machine, water inlet 2 is connected with compression pump, and delivery port 3 is connected with coffee extractor with boiler, pressure relief opening 4 be connected pressure relief opening 5 and be connected with water tank.When the pipeline of boiler or coffee extractor occurs to stop up; produce the effect of steam because of boiler; the pressure anomaly at delivery port 3 places is increased; at this moment; piston 6 can axially be return under the effect of this pressure and back-moving spring 7 and reset; delivery port 3 and pressure relief opening 4 are communicated and pressure release, reach the safeguard protection effect.
The flow of small pressure relief opening 5 water outlet pressure releases is significantly smaller than the flow of inlet water of water inlet 2, thereby does not affect the pressure of the required water inlet 2 of extraction coffee, and is in all the time in the course of the work the pressure release state.
Operation principle of the present utility model is: when water inlet 2 water filling, because being subjected to the resistance of spool 8, can make piston 5 move axially and seal pressure relief opening 4 towards the direction of delivery port 3, at this moment, delivery port 3 and pressure relief opening 4 do not communicate, and piston 6 continues to move to that stopped by spacing control mobile, make the pressure at water inlet 2 places continue increase and open spool 8, water inlet 2 and delivery port 3 communicate, and at this moment, can make coffee.After making coffee is complete; water inlet 2 stops water filling; be subjected to the pressure release effect of small pressure relief opening 5 and delivery port 3 the keeps effect of pressure and the effect of returning spring 7; piston 6 is axially opened pressure relief opening 4 thereupon mobile returning; pressure relief opening 4 is communicated and pressure release with delivery port 3, reach the effect of safeguard protection, at this moment; can take out coffee capsule or ground coffee after having made, and a cup of Java under the new making that can change the outfit.
Above-described embodiment is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that does not break away from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
