For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of reduction valve, comprising:
Valve body, it has fluid input;
Be connected to the valve gap of described valve body one end, it has fluid output;
Be installed on the piston of described valve inner, the combination of lumens of its one end and valve body forms a valve pocket, and this valve pocket is communicated with a cavity by a constant current through hole, and this cavity is arranged on described valve inner and is communicated with described fluid input; Its inside of described piston has the fluid passage being communicated with this valve pocket and fluid output;
Connect the mobile control piece of described piston, for controlling the movement of described piston.
Preferably, above-mentioned reduction valve, wherein said mobile control piece is helical spring.
Preferably, above-mentioned reduction valve, wherein said helical spring is set in the periphery of described piston, and the pedestal of its one end and described piston offsets, and the other end and a spring fixed seat offset, and this spring fixed seat is connected to the periphery of the head of described piston.
Preferably, above-mentioned reduction valve, the head of wherein said piston is provided with sealing gasket near described valve pocket position, is connected with the bore seal of described valve body.
Preferably, above-mentioned reduction valve, the pedestal of wherein said piston and the inner chamber joint of described valve body are provided with flat circle, play seal action.
Preferably, above-mentioned reduction valve, wherein said valve gap one end is connected with the inner chamber of described valve body, connects part and is provided with O shape circle for sealing.
Preferably, above-mentioned reduction valve, wherein said valve gap is provided with jump ring back-up ring near the inner chamber connection of the side of described fluid output and described valve body.
Preferably, above-mentioned reduction valve, the bottom of the pedestal of wherein said piston is provided with arc groove, and the position of this arc groove is corresponding with described fluid output.
Technique effect of the present utility model is mainly reflected in: the utility model whole assembly compact structure, connected element is few, moved up and down by the inner chamber axial direction of mobile control piece control piston at valve body, the pressure higher by fluid input is reduced to the level needed for fluid output.
Accompanying drawing explanation
Fig. 1: the utility model original state structural representation;

In figure, the implication of each reference character is: 1-valve gap, 2-jump ring back-up ring, and 3-O shape is enclosed, 4-flat circle, 5-piston, and 6-moves control piece, 7-valve body, 8-spring fixed seat, 9-sealing gasket, 10-camber line groove; A-fluid input, B-cavity, C-valve pocket, E-constant current through hole, F-fluid passage, K-fluid output.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail, is easier to make technical solutions of the utility model understand and grasp.
As shown in Figure 1, a kind of reduction valve, comprising:
Valve body 7, it has fluid input A;
Be connected to the valve gap 1 of valve body 7 one end, it has fluid output K;
Be installed on the piston 5 of valve body 7 inside, the combination of lumens of its one end and valve body 7 forms a valve pocket C, and this valve pocket C is communicated with a cavity B by a constant current through hole E, and this cavity B is arranged on valve body 7 inside and is communicated with fluid input A; Its inside of piston 5 has the fluid passage F being communicated with this valve pocket C and fluid output K;
Connect the mobile control piece 6 of piston 5, for the movement of control piston 5.
Mobile control piece 6 is helical spring, and helical spring is set in the periphery of piston 5, and the pedestal of its one end and piston 5 offsets, and the other end and a spring fixed seat 8 offset, and this spring fixed seat 8 is connected to the periphery of the head of piston 5.
The head of piston 5 is provided with sealing gasket 9 near valve pocket C position, is connected with the bore seal of valve body 7.
The pedestal of piston 5 and the inner chamber joint of valve body 7 are provided with flat circle 4, play seal action.
Valve gap 1 one end is connected with the inner chamber of valve body 7, connects part and is provided with O shape circle 3 for sealing.
Valve gap 1 is provided with jump ring back-up ring 2 near the inner chamber connection of the side of fluid output K and valve body 7.
The bottom of the pedestal of piston 5 is provided with arc groove 10, and the position of this arc groove 10 is corresponding with fluid output K.
By describing above and can finding out, the utility model whole assembly compact structure, connected element is few, is moved up and down, the pressure higher by fluid input is reduced to the level needed for fluid output by the inner chamber axial direction of mobile control piece control piston at valve body.
Certainly, the exemplary illustration of the above only the utility model typical apply, by the combination of same or similar technical characteristics and replacement, can form multiple concrete scheme, these schemes all drop within protection domain of the present utility model.
