Further, between upper side and the upper valve body of described decompression piston, there is gap.
Further, between the recess sidewall of decompression piston and lower valve body, and sealing ring between piston rod and relief groove, it is equipped with.
Compared with prior art, this utility model has the advantage that
1, by arranging cock on lower valve body, play the effect of stop valve for cylinder, and become one with air relief valve, be that gas cylinder is opened with decompression two functions on a valve such that it is able to effectively reducing overall volume, weight is lighter, and uses convenient.
2, by decompression piston, piston rod and the cooperation of relief spring, make to be always medium pressure gas through middle extrusion QI KOU effluent air, thus ensure the stability of decompression.
3, also leaving high pressure expansion joint on lower valve body, can be used for connecting other gas cylinder or Pressure gauges etc., lower valve body becomes one 5 and leads to valve body, further Appropriate application space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be Fig. 1 along A A to sectional view.
In figure: 1 upper valve body, 2 times valve bodies, extrude QI KOU, 4 cylinder interfaces, 5 expansion interfaces, 6 cocks, 7 relief grooves, 8 decompression pistons, 9 piston rods, 10 relief springs, 11 inflatable interfaces in 3.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: seeing Fig. 1, Fig. 2, the bottle valve of a kind of band decompression, including upper valve body 1 and lower valve body 2, described lower valve body 2 upper end has a groove, and described upper valve body 1 is connected with the upper end of lower valve body 2, and the groove of lower valve body 2 is closed, form valve pocket；In the upper end of upper valve body 1 is provided with, extrudes QI KOU 3, is provided with cylinder interface 4 in the lower end of lower valve body 2.
Being provided with an expansion interface 5 in the side of lower valve body 2, opposite side is provided with cock 6 groove, is provided with cock 6 in cock 6, is provided with sealing block in this cock 6；Described expansion interface 5 is connected air flue with cock 6 groove by one and is connected, by rotating cock 6, it is possible to make the sealing block on cock 6() one end opening and closing of fault that air flue is connected will be connected with cock 6 groove；Described cylinder interface 4 is by being connected with being connected air flue with the gas port of its eccentric setting.
Bottom portion of groove at lower valve body 2 is provided with a relief groove 7, and the bottom of described relief groove 7 is connected with cock 6 groove by pressure relief valve port.A decompression piston 8 it is provided with in groove, this decompression piston 8 is slidably matched with upper valve body 1 and is connected, a piston rod 9 it is provided with in the lower section of decompression piston 8, the upper end of described piston rod 9 is connected with decompression piston 8, lower end is stretched in relief groove 7, it is provided with sealing block in the lower end of piston rod 9, between decompression piston 8 and lower valve body 2, is provided with relief spring 10.Further, between upper side and the upper valve body 1 of decompression piston 8, there is gap.Being provided with in one on decompression piston 8 and calm the anger, decompression piston 8 is run through in the upper end calmed the anger in this, and lower end extends to the bottom of piston rod 9, the bottom of piston rod 9 be provided with in calm the anger to the via connected.During work, gases at high pressure enter pressure relief valve port, reduced pressure by pressure relief valve port, form medium pressure gas, post-decompression medium pressure gas is calmed the anger in the via of piston rod 9 lower end enters, enter extrusion QI KOU 3 in the gap between decompression piston 8 and upper valve body 1, and warp after calming the anger in through and carry out medium pressure gas output.When medium pressure gas pressure in gap between decompression piston 8 and upper valve body 1 is excessive, gas push piston moves down, until pressure relief valve port is closed by the lower end of piston rod 9, so, no longer has gases at high pressure to enter；After medium pressure gas flows out, relief spring 10 promotes and moves on piston, is again opened by pressure relief valve port；In practical work process, decompression piston 8 ceaselessly moves up and down under the effect of gas and relief spring 10, so that it is guaranteed that the gas of output is always medium pressure gas.
Lower valve body 2 is additionally provided with an inflatable interface 11, in this inflatable interface 11, is provided with stop valve.
During use, gas cylinder is threaded connection with the cylinder interface 4 of lower valve body 2, and seals at bottle mouth position high-pressure seal ring.Gases at high pressure enter valve body by cylinder interface 4, and by accessing high pressure expansion interface 5 after gas port and connection air flue, this interface can access residual gas pressure in other gas cylinder, or Pressure gauge detection gas cylinder as required.Meanwhile, gases at high pressure enter pressure relief valve port through the connection air flue opened.When usually not using, one end that connection air flue connects with cock 6 groove is sealed by cock 6, and handle of outwarding winding during use is opened；Gases at high pressure flow into pressure relief valve port, make gas pressure be reduced to middle pressure, and medium pressure gas is by pressure pipe road in the inflow of middle extrusion QI KOU 3.Having an inflatable interface 11 on lower valve body 2, this interface is filled with gas cylinder for gas, accesses loading line during inflation, open stop valve, and air flue closing will be connected by cock 6, make gas be filled with gas cylinder, close stop valve after completing, after taking off loading line, complete inflation.
Finally it should be noted that, above example is only in order to illustrate the technical solution of the utility model rather than restriction technologies scheme, it will be understood by those within the art that, the technical solution of the utility model is modified or equivalent by those, without deviating from objective and the scope of the technical program, all should contain in the middle of right of the present utility model.
