Embodiment
the invention will be further described below in conjunction with accompanying drawing: as can be known with reference to the accompanying drawings, a kind of gas pressure controlling device of the present invention, mainly comprise pressure regulating screw 1, spring compressor 2, spring 3, spring groove 4, circular steel disk 5, round rubber dish 6, air outlet 7, trap valve 8, filter screen 9, housing main body 10, shell cap 11, trap valve end socket 12, filter core 13, suction port 14, striker 15, box thread 16 and fixing frame 17, wherein, housing main body 10 1 sides are provided with suction port 14, around suction port 14, be provided with the box thread 16 that connects air cylinder, suction port 14 centers are provided with the striker 15 of hollow, and trap valve 8 is equipped with at housing main body 10 Yi Duande centers, and trap valve 8 one ends are provided with filter screen 9, to the other end, are provided with successively spring, filter core 13 and trap valve end socket 12, trap valve end socket 12 centers are provided with aperture, filter core 13 1 ends can be from stretching out the aperture of trap valve end socket 12, trap valve 8 outwards is disposed with round rubber dish 6 and circular steel disk 5, between trap valve 8 and suction port 14, being provided with air flue communicates, housing main body 10 1 sides are provided with air outlet 7, between air outlet 7 and round rubber dish 6, have air flue to communicate.Wherein, round rubber dish 6 plays the effect in space between sealing and trap valve 8.
a kind of gas pressure adjustment device work principle of the present invention is: during use, to store nitrogen, CO2, the air cylinder of the compression gases such as air is arranged on the suction port 14 of gas pressure controlling device by box thread 16, the striker 15 of gas pressure controlling device will puncture the mounting of air cylinder, allow nitrogen, CO2, hollow pipeline and gas channel and the filter screen 9 of the pressurized gas such as air by striker 15 enters into trap valve 8, the gas micro-gap between valve body and filter core 13 and the micro-gap between filter core 13 and trap valve end socket 12 after filtration enters into the space between round rubber dish 6 and trap valve 8, then by gas channel, enter air outlet, in the gas flow process, filter screen 9, trap valve 8, filter core 13, trap valve end socket 12 and round rubber dish 6 play the mitigation of gases Negotiation speed jointly, hypobaric effect is fallen.
Tighten clockwise pressure regulating screw 1, spring compressor 2 pushes spring groove 4 by spring 3 and inwardly compresses circular steel disk 5 and round rubber dish 6, then inwardly push filter core 13, thereby the pressure increase make to enter again by the compression gases such as nitrogen, CO2, air that filter screen 9 enters into trap valve 8 inside gas delivery port 7 is strengthened in the gap between filter core 13 and trap valve end socket 12, will tune up the gas output pressure value like this.
Loosen counterclockwise pressure regulating screw 1, thereby will circular steel disk 5 and round rubber dish 6 be loosened by spring compressor 2, spring 3 and spring groove 4 presses the top of filter core 13, thereby the pressure that the gap smaller between filter core 13 and trap valve end socket 12 makes to enter into gas delivery port 7 by the compression gas such as nitrogen, CO2, air that filter screen 9 enters into trap valve 8 reduces, and will turn down the delivery pressure value like this.
As a further improvement on the present invention, around described housing main body 10, can be provided with a plurality of air outlets 7.
As a further improvement on the present invention, describedly at housing main body 10 1 ends, be provided with fixing frame 17.
Above embodiment is only be used to illustrating that technological scheme of the present invention is not intended to limit, and the equivalent transformation that all utilizations specification of the present invention and accompanying drawing are done, all belong to the scope of the claims that the present invention asks for protection.
