The area of the lower end surface 353 of spool 35 is greater than the area of housing endoporus 312, also greater than the area of upper-end surface 352, and this upper-end surface ora terminalis contacted with the ring inclined-plane with the endoporus 312 of housing 31.
On valve body skirt 13 mount inlets on T-valve body 1 top, filling valve 10 is housed, this filling valve comprises that one is installed in the fast interface 50 on the valve body skirt 13, fast interface 50 comprises that a free end has the valve seat pipe 52 of inlet opening 520, one is installed in valve core housing 55 in the valve seat pipe 52 with skirt in abutting connection with ground, one is step-like spool 53, one of this stepped shaft spool 53 is plugged in the center hole of valve core housing 55 movably, the airtight contact of hole wall of other end and valve seat pipe 52 inlet openings 520, one is sleeved on second spring 54 on the stepped shaft spool 53 and between the shoulder of valve core housing 55 and spool 53.Also has the handle 11 that is installed in T-valve seat 1 top, can be connected, drives the valve rod mechanism rotation with to the control valve linkage that the medium that enters skirt does to open and close.
Valve rod mechanism comprises that the valve rod of being located in T-valve seat 1 topped hole 14 and is installed in the ball valve body 12 in the cross-shaped portion of the skirt 13 of T-valve seat 1 and vertical tube, and an end of valve rod 14 links to each other with handle 11, and the other end links to each other with ball valve 12.
Be positioned near being provided with concave ring part 525 on the inwall of skirt 13 front ends at valve seat pipe 52, valve core housing 55 is made up of board 551 and cover portion 552, is provided with some through holes 553 on board 551, and the board 551 of valve core housing 55 is fixed in the concave ring part 525.
On the back outer circumferential face of valve seat pipe 52, be provided with a bulge loop 523, on preceding outer circumferential face, be provided with a circular groove 524, filling valve 10 also comprises a cutting ferrule 58, one the 3rd spring 56 and a spring collar 60, cutting ferrule 58 is established shoulder hole and in preceding stage portion one groove 581 is arranged on inwall, cutting ferrule 58 is sleeved on the valve seat pipe 52 by groove 581, described spring collar 57 cutting ferrules are in the annular groove 581 of cutting ferrule 58, and be located between the bulge loop 523 of valve seat pipe 52, described the 3rd spring 56 is installed in bulge loop 523 and cutting ferrule 58 between the shoulder of the preceding rank of inwall portion.When fast interface 50 and external special purpose interface socket, a side of cutting ferrule 58 covered circular groove 524 under the 3rd spring action.
When to pressurized container liquified petroleum gas cylinder filling liquefied petroleum gas, special joint is enclosed within on the quick connection mouth 50, the inner core of special joint withstands on the seal face 51, makes seal face and inlet gapped between 520, and cutting ferrule 58 is fixed on special joint on the fast interface 50 simultaneously; Open filling valve 10, liquid gas in regular turn through enter the mouth 520, through hole 553, valve body skirt 13, ball valve body 12, pipeline 2 on the seal face 51, board 551 enter in the anti-overcharge valve 30.Because during original state, cursory 32 of cursory lever is in the shape that hangs low, at this moment, connecting rod 33 tilts, the protuberance of the concavo-convex cambered surface 341 of the curve-like on the interlock termination 34 just is resisted against the lower end of live axle 39, live axle is replaced by the protuberance of cambered surface 341, promotes the globule 301 up center holes 382 that leave cylinder cap 38 of its upper end, makes between globule 301 and the center hole 382 and forms clearance channel; The radial hole 361 of the center hole 351 of liquid gas spool 35 in pipeline 2, housing 31, the spheroid in the housing 31 cover 36, the center hole 382 of cylinder cap 38, after the exit orifice of offering on the cylinder cap 38 381 that connects with center hole 382 enter in the container.
The upper and lower end face pressure reduction of spool 36 is bigger simultaneously, liquid gas is at stressed much larger than inside lower end face 353 of the upper-end surface 352 of spool 35 stressed, this difference force promotes spool 35 and moves down, and liquid gas enters in the container through gap, the outlet 311 of pipeline 2, inlet 312 and upper end 352.
Liquid gas in container charges some, when promptly having reached the precalculated position, air pressure holds up cursory 32, move the interlock termination 34 of drivening rod 33 the other ends, the protuberance of the cambered surface 341 on the interlock termination moves apart live axle, the globule 301 that is contacted by top on it hangs naturally in the following bottom of oil hydraulic cylinder, just the vertical centre hole 382 of cylinder cap 38 and the Horizontal Exit hole 381 of the side on the cylinder cap are blocked, forming down, outlet 381 is a closed condition, and upper outlet 311 is an open state, at this moment, liquid gas still continues to enter the container from exporting 311.The upper-end surface of anti-overcharge spool 35 has a center hole 351, liquid gas also constantly enters the inboard of spool 35, the pressure of spool 35 inboards is raise, pressure reduction between upper-end surface 352 and the lower end surface 353 reduces, the upwards thrust that lower end surface 353 is subjected to increases, when last thrust during greater than the downward thrust of upper-end surface 352, spool 35 begins to move up.Along with liquid gas continue enter, make poor gradually the tending to balance of upper and lower end face institute pressurized of spool at last.Because the area of the lower end surface 353 of spool 35 is greater than the area of housing endoporus 312, also greater than the area of upper-end surface 352, make spool 35 stressed moving up, and then end entrance on the oil hydraulic cylinder 312 closed, can is stopped automatically, this anti-overcharge valve, it is a certain amount of that the can liquid gas is limited to, unlikely owing to overcharge, and cause danger.
When using fast interface, valve seat pipe 52 is entangled in the adapter of special purpose interface, spheroid contact cutting ferrule 58 in the adapter in the radial hole retreats, after cutting ferrule 58 retreated hollow toroid groove 525, spheroid falls into hollow toroid groove 525, cutting ferrule 58 is ejected forward and was covered hollow toroid groove 525 by the effect of the 3rd spring 59, and special purpose interface is pinned.The nozzle inner wall of special purpose interface is embedded with O-ring seals simultaneously, the sealing circle is when taking over insertion valve seat pipe 52, valve seat pipe 52 is inserted in, between the adapter of valve seat pipe 52 and special joint, form sealing, taking over inner core simultaneously backs down seal face 51, external pipe is communicated with filling valve, thereby fast interface 50 is covered on the external special joint fast and hermetically, to carry out the can safely smoothly of liquid gas.
Referring to Fig. 3,4, Fig. 3 is the plan structure figure of multi-functional combination brake switch and proporting simultaneously, and among the figure, gaseous state outlet valve 20 comprises a control handwheel 21, one rectangular breathing pipes, and this breathing pipe one end opening is gaseous state outlet 24, and the other end is to stop valve 22.When the gas that gasifies exports 24 from gaseous state inlet 22 through stop valve 23, breathing pipe, gaseous state, enter the laggard access customer pipeline of outside reduction valve.
Fig. 4 is the A-A sectional view of Fig. 3, and among the figure, gaseous state pressure equalizing valve 40 comprises the pressure equalizing valve inlet 44 that a Joystick 41, one ball valves 42, one pressure equalizing valves outlet 43, is opposing with this pressure equalizing valve outlet and establish.When gaseous pressure 43 enters ball valve 42 through entering the mouth, with Joystick 41 ball valve 42 to be opened, pressure makes the gaseous pressure in the container consistent with the gaseous pressure in the tank car through exporting the 44 gas phase pipes that enter the can tank car, is accomplished in can.
