Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiments.
A kind of novel anti-gas valve that fills of embodiment as shown in Figures 1 to 5, comprises being provided with the valve body 1 of inflation inlet 11, coordinating with this valve body 1 and the spool 2 of both ends open; In spool, be provided with the anti-parts 3 of disclosing, inflation inlet 11 is positioned at this anti-parts 3 tops of disclosing, and prevents that disclosing parts 3 is provided with the first pod apertures 31 being communicated with inflation inlet 11; In spool 2, be also provided with the second pod apertures 21 being communicated with the first pod apertures 31, this second pod apertures 21 is located at and anti-is disclosed parts 3 belows, and these the second pod apertures 21 inside are provided with and make the second pod apertures 21 sealing or unimpeded closure members 4.
The cross section of the second pod apertures 21 is trapezium structure or cone structure wide at the top and narrow at the bottom, end opening 211 shapes of the shape of closure member 4 and the second pod apertures match (cross section that is closure member 4 is trapezium structure, cone structure or round structure), and suitable for reading 212 of the second pod apertures is communicated with the first pod apertures 31.Closure member 4 is along the second pod apertures 21 displacements, thereby realize the second pod apertures 21 sealings or unimpeded: the second pod apertures 21 sealings when the end opening 211 of closure member 4 and the second pod apertures is connected, the second pod apertures 21 is unimpeded when the end opening 211 of closure member 4 and the second pod apertures is separated.The cross section of the second pod apertures 21 in the present embodiment and the cross section of closure member 4 are trapezium structure.The preferred magnetic material of closure member 4 is made, or closure member 4 combines for magnetic material and plastics.
The present embodiment also comprises that end opening 211 positions of anti-dismounting structure 5, the second pod apertures are provided with groove 22, and anti-dismounting structure 5 is located in groove 22; Groove 22 is low inside and high outside structure.Anti-dismounting structure 5 comprises push rod 51, the ball 52 of being located at push rod outer end 511 of being located in groove 22 and is sheathed on the spring 53 on push rod, push rod inner 512 and closure member 4 coordinate, spring 53 one end connect ball 52 and the other end is connected on groove the inner 221, ball 52 and 222 clampings of groove outer end.Preferably 20 °~70 ° of the angles of groove 22 and horizontal plane.
In the present embodiment, spool comprises the first spool portion 23 and second valve core 24, the first spool portions 23 that contact with cylinder for liquefied gas and the section constitution inverted T shape structure of second valve core 24, and the first spool portion 23 inserts in valve body 1, and groove 22 is positioned at second valve core.
The first pod apertures 31 in the present embodiment consists of several equally distributed first pod apertures unit 311, the first cylindrical structure in pod apertures unit 311 and run through the anti-parts 3 of disclosing.The anti-parts 3 of disclosing are for cylindrical structure, and 9 the first pod apertures unit 311 are around anti-center annular arranged in arrays of disclosing parts 3, thereby and the first pod apertures unit along the anti-Axis Extension of disclosing parts 3, run through the anti-parts 3 of disclosing.Anti-disclose the outer side wall of parts 3 and the inwall of spool 2 is connected.
As to further improvement of this embodiment, the present embodiment also comprises the radio frequency transmitter 6 for transmitting to storage data device, and this radio frequency transmitter 6 is positioned at valve body 1, and is positioned at the position of matching with air-filled pore 11.Automatic storage data set is arranged on outside the present embodiment, when radio frequency transmitter 6 senses the special inflation air gun of the interior insertion special use of inflation inlet 11, radio frequency transmitter 6 is towards the id signal of automatic storage data set transmitting the present embodiment, automatic storage data set stores read-write according to this id signal to inflation data and the management data information of the cylinder for liquefied gas of use the present embodiment, thereby realize, will process implementation automation that use the cylinder for liquefied gas of the present embodiment valve to fill liquid gas be controlled, realize and whether automatically detect this propane gas steel cylinder for not detecting bottle, scrap liquid steel cylinder, determine whether that cylinder for liquefied gas fills gas.
A kind of novel anti-other structure that fills gas valve of the present embodiment is referring to prior art.
As to the further illustrating of the present embodiment, the working principle of anti-dismounting structure 5 is now described:
S1, cylinder for liquefied gas when inflation as shown in Figure 4, use special-purpose special inflation air gun, closure member 4 is upwards moved to the end opening 211 of the second pod apertures and is separated under the suction-operated of inflation air gun, realizes the second pod apertures 21 unimpeded, thereby realizes inflating in bottle.
S2, when there is combustion gas cylinder for liquefied gas inside as shown in Figure 4, closure member 4 under the effect of bottle internal air pressure to top offset, and and being separated of the end opening 211 of the second pod apertures, realize the second pod apertures 21 unimpeded, thereby make bottle an interior combustion gas can flow out a bottle use outward.
S3, as shown in Figure 5, when cylinder for liquefied gas inside is during without combustion gas, closure member 4 is moved to downwards with the end opening 211 of the second pod apertures and is connected, and realizes the second pod apertures 21 sealings.Now anti-dismounting structure 5 is further reinforced the connection of spool and cylinder for liquefied gas, play Anti-dismantling effect: cylinder for liquefied gas inner wall sleeve is located on the outer wall of second valve core 24, closure member 4 props up push rod the inner 512, under the effect of spring 53 and push rod 51, a part for ball 52 is exposed spool 2 and is propped up cylinder for liquefied gas inwall, thereby further fixing cylinder for liquefied gas, plays Anti-dismantling effect.Need special-purpose special extracting tool could the present embodiment valve be dismantled separated with cylinder for liquefied gas.
The present invention is not limited to above-mentioned mode of execution, if various changes of the present invention or modification are not departed to the spirit and scope of the present invention, if within these changes and modification belong to claim of the present invention and equivalent technologies scope, the present invention is also intended to comprise these changes and modification.
