Described connected element 224 comprises nut 2242, epithelium 2243, pad 2241.Described controlling rod 225 is arranged on the below of epithelium 2243 and is connected with it; Described pad 2241 is connected to the top of epithelium 2243; Described button spindle 222 is fixed on the top of pad 2241 by nut 2242.
Described controlling rod 225 is provided with movable axis 2252, V-type groove 2251.Described V-type groove 2251 is arranged on controlling rod 225, and laterally places, and one end of suction port 111 is pointed at the tip of this V-type groove 2251; Described movable axis 2252 is arranged on the inside of V-type groove 2251, can be freely movable in V-type groove 2251.
Described valve port unit 21 comprises sealing valve port pad 211, motion bar 215, opens and closes spring 213, spring card 214.Described sealing valve port pad 211 is connected to one end of motion bar 215, and the other end of this motion bar 215 is connected with the movable axis 2252 of driving mechanism 22.Described spring card 214 is fixedly installed on motion bar 215, and this keying spring 213 to be set on motion bar 215 and to be connected with spring card 214.The other end of this keying spring 213 is fixedly mounted on valve seat 11.Movable in V-type groove 2251 by movable axis 2252, thus drive motion bar to carry out applying pressure to the keying spring on motion bar 215.By the effect of this keying spring 213, control valve port sealing gasket 211 and separate with valve port 212 or be close to.
Refer to Fig. 4, it is the structural drawing of main valve.Described main valve 3 comprises valve pad 307 of giving vent to anger, small magnet 308, power assistant spring 310, spring top flat 301, manually operated valve pipe 304, magnet frame 309, the first armature 302, large magnet 303 and the second armature 305; Described small magnet 308 is arranged on inside magnet frame 309.This magnet frame one end is connected to valve pad 307 of giving vent to anger, and the other end is connected with spring top flat 301 by power assistant spring 310.This spring top flat 301 is fixed on valve seat 11.In air outlet 112, outer wall is provided with manually operated valve pipe 304; First armature 302 is arranged on one end of manually operated valve pipe 304 and is connected with valve gap 12, and the second armature 305 is arranged on the other end of manually operated valve pipe 304.Described large magnet 303 is arranged in the middle of the first armature 302 and the second armature 305, and can move along manually operated valve pipe 304.
Please refer to Fig. 5 and Fig. 6, wherein, Fig. 5 is the phase diagram that valve is normally opened, and Fig. 6 is the phase diagram that valve is normally closed.The working procedure that this gas valve is normally opened is: when mentioning button 2211, driving button spindle 222, driving epithelium 2243, move up by button spindle 222 by carrying button 2211.Because epithelium 2243 drives the V-type groove 2251 on controlling rod 225 to move up, movable axis 2252 is made to move to the V-type tip of V-type groove 2251, spring 213 is opened and closed by motion bar 215 times compressions, thus the sealing valve port pad 211 of motion bar 215 left end is separated with valve port 212, now valve port 212 conducting.
After mentioning button 2211 relieving, under the effect due to Returnning spring 2212, can make to carry button 2211 and reset.Now, the first armature 302 is departed from again and after manually operated valve pipe 304 and the second armature 305 adhesive with the large magnet 303 of hand propulsion, under the effect that large magnet 303 and small magnet 308 repel mutually at homopolarity, magnet frame 309 brute force compression power assistant spring 310 is driven by small magnet 308, valve pad 307 of now giving vent to anger separates with sealing plane 306, air outlet 112 conducting.
The working procedure of throttle down under normal working: when pipeline is in normal work, during throttle down, first pressed by button spindle 222, drives epithelium 2243 to move down, drives controlling rod 225 to move down by epithelium 2243.Now, the movable axis 2252 inside V-type groove 2251 can move to the top of V-type groove 2251.Drive motion bar 215 to move right by movable axis 2252, now by the effect opening and closing spring 213, sealing valve port pad 211 is closed with valve port 212 and pastes extremely.Afterwards, the large magnet 303 at air outlet place is being moved to left, due to the repulsion mutually with small magnet 308, can promote small magnet 308 phase right and move, valve pad 307 of giving vent to anger is adjacent to mutually with sealing plane 306, and air outlet is closed.
Refer to Fig. 7, it is gas valve internal low-voltage or structural representation with no pressure.When air pressure below epithelium 2243 is too low, due to the pressure born below epithelium 2243 be less than the pressure above epithelium 2243 time, epithelium 2243 can drive controlling rod 225 to move down, and the movable axis 2252 inside V-type groove 2251 can move to the top of V-type groove 2251; Now, under the effect of elastic force opening and closing spring 213, it is dead that the sealing valve port pad 211 on keying spring 213 brute force promotion motion bar 215 one end and valve port 212 close note, thus cut-out source of the gas.
Automatically close due to low-pressure state at valve, and when pipeline recovers normal air feed, when reopen valve, button 2211 can be mentioned, driving button spindle 222 by carrying button 2211, driving epithelium 2243 by button spindle 222, move up.Because epithelium 2243 drives the V-type groove 2251 on controlling rod 225 to move up, movable axis 2252 is made to move to the V-type tip of V-type groove 2251, spring 213 is opened and closed by motion bar 215 times compressions, thus the sealing valve port pad 211 of motion bar 215 left end is separated with valve port 212, now valve is opening state.
Refer to Fig. 8, it is the structural representation of the inner ultrahigh pressure of gas valve.When manifold pressure is too high, because the pressure born below epithelium 2243 is excessive, can move up, button spindle 222 is driven to move up, boss 2233 now on button spindle 222 can back down thimble 2232, boss 2233 can move to the top of thimble 2232, and now thimble 2232 under the effect of resistance spring 2231, can block the below of boss 2233.At the same time, the V-type groove 2251 of controlling rod 225 can move up, thus the movable axis 2252 in V-type groove 2251 is moved down, and the sealing valve port pad 211 now opening and closing spring 213 brute force promotion motion bar 215 one end closes note extremely with valve port 212, thus cuts off source of the gas.
Be in high pressure at valve and when automatically closing, when pipeline recovers normal air feed, can press the button bar 222, the boss 2233 on this button spindle 222 can back down the thimble 2232 on the both sides below boss 2233, moves down.By button spindle 222 to pressing down epithelium 2243, controlling rod 225 is driven to move down by epithelium 2243; Now, movable axis 2252 can move to the tip of this V-type groove 2251 in V-type groove 2251.Thus drive motion bar 215 to compress keying spring 213, and the sealing valve port pad 211 of motion bar 215 left end is separated with valve port 212, now, valve is opening state.
The present invention can have various deformation mode of execution, as one end of the sensing air outlet, tip 112 by V-type groove 2251 set on controlling rod 225, this sealing valve port pad 211 is arranged on the inside of valve port passage.
The present invention is not limited to above-mentioned mode of execution, if do not depart from the spirit and scope of the present invention to various change of the present invention or distortion, if these are changed and distortion belongs within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these changes and distortion.
