Abstract
The utility model relates to a valve device of pressure coffee machine, which comprises a valve body 1, a valve plug 2, wherein the valve body 1 is provided with three passages 11, 12, 13, the passage 11 is connected with a force pump 4 of the pressure coffee machine, the passage 12 is connected with a boiler 5 of the pressure coffee machine, the valve plug 2 is capable of moving between the passage 11 and the passage 13 to and fro. When the force pump 2 is at work, the valve plug 2 moves toward the passage 13 and closes the passage 13 and the passage 11 is connected with the passage 12. When the force pump 4 is not at work, the valve plug 2 moves toward the passage 11 and the passage 12 is connected with the passage 13. Compared with the prior art, the valve plug 2 moves between the passage 11 and the passage 13. When the force pump 4 is at work, the valve plug 2 moves upward to close passage 13 and the passage 11 is connected with the passage 12 to make the coffee machine of 8-15 BAR voltage. When the force pump 4 is not at work, the valve plug 2 downwardly moves to the passage 11 to connect passage 12 and 13 to make the coffee machine pressure release from passage 13. The said structure is simple and convenient for user to unload the filter and ensures safety.
Description
Technical field
The utility model relates to a kind of control valve unit, the control valve unit that particularly a kind of pressure coffee machine of release pressure is automatically used
Background technique
The existing pressure coffee machine that pumps up is when brewing coffee, and coffee machine generally all has the pressure of 8～15BAR; After coffee brewing finishes, have certain pressure in the coffee machine, coffee machine does not have pressure releasing means yet, and under these circumstances, the user not only will apply bigger active force just can unload filter; And in unloading the process of filter, steam or coffee liquid can spray to the user under pressure, threaten for user's safety.
The model utility content
In order to overcome the above-mentioned defective of prior art, the control valve unit that the utility model provides a kind of pressure coffee machine of automatic release pressure to use.
The technological scheme that the utility model adopted is: the control valve unit that pressure coffee machine is used, comprise valve body 1, spool 2 compositions, valve body 1 is provided with passage 11, passage 12 and passage 13, passage 11 is connected with the pressure pump 4 of pressure coffee machine, passage 12 is connected with the boiler 5 of pressure coffee machine, and spool 2 can move back and forth between passage 11 and passage 13;
Wherein when pressure pump 4 work, spool 2 moves closing passage 13 towards passage 13 directions, and passage 11 and passage 12 are connected; When pressure pump 4 was not worked, spool 2 moved towards passage 11 directions, and passage 12 and passage 13 are connected.
Described spool 2 moves towards passage 11 directions under the effect of self gravitation passage 12 and passage 13 is connected.
Described passage 13 internal fixation one apply the spring 3 of elastic force to spool 2.
One end of described spool 2 is with a silicone-rubber seals 21.
During described spool 2 closing passages 13, spring 3 compresses mutually with spool 2, and when spool 2 was shifted to passage 11, spring 3 did not contact with spool 2.
Described valve body 1 also has a passage 14, is provided with safety valve 141 in the passage 14.
Described passage 13 is connected with water tank 6 respectively with passage 14.
Compared with prior art, the spool 2 of control valve unit of the present utility model moves between passage 11 and passage 13, during pressure pump work, and spool 2 closing passage 13 that moves up, passage 11 and passage 12 are connected, and make the coffee function keep the pressure of 8～15BAR; During the pressure air pump inoperative, spool 2 moves towards passage 11 directions downwards, and passage 12 and passage 13 are connected, and the pressure of coffee machine can discharge automatically from passage 13, the control valve unit that such pressure coffee machine is used has simple in structure, guarantees user's safety when allowing the user unload filter easily.
Description of drawings
Fig. 1 is the sectional view of the control valve unit used of pressure coffee machine;
Fig. 2 is to use the schematic representation of the pressure coffee machine of control valve unit shown in Figure 1.
Embodiment
As shown in Figure 1 and Figure 2, the control valve unit that a kind of pressure coffee machine of the present utility model is used, comprise valve body 1, spool 2 compositions, one end of spool 2 is with a silicone-rubber seals 21, valve body 1 is provided with passage 11, passage 12 and passage 13, and passage 11 is connected with the pressure pump 4 of pressure coffee machine, and passage 12 is connected with the boiler 5 of pressure coffee machine, pressure pump 4 is used for the water in the water tank 6 is transported to boiler 5 heating, enters filter 7 brewing coffees again after the water heating.
Spool 2 can move back and forth between passage 11 and passage 13; Wherein when pressure pump 4 work, spool 2 moves closing passage 13 towards passage 13 directions, and passage 11 and passage 12 are connected, and makes the water in the water tank 6 can enter into heating in the boiler 5; When pressure pump 4 was not worked, spool 2 moved towards passage 11 directions under the effect of self gravitation, and passage 12 and passage 13 are connected, and steam or water in the boiler 5 are discharged by passage 13, thus the pressure in the release pressure coffee machine; Passage 13 internal fixation one apply the spring 3 of elastic force to spool 2, and spring 3 compresses mutually with spool 2 during spool 2 closing passages 13; When spool 2 was shifted to passage 11, spring 3 did not contact with spool 2.Valve body 1 also has a passage 14, be provided with safety valve 141 in the passage 14, passage 13 is connected with water tank 6 respectively with passage 14, when the pressure in the boiler 5 during greater than safety valve 141, safety valve 141 is just opened, and steam in the boiler 5 or hot water are by in passage 14 reflow tanks 6; When pressure pump 4 was not worked, passage 12 and passage 13 were connected, behind steam in the boiler 5 or the water inlet passage 12 again in inlet passage 13 reflow tanks 6.
