Please refer to Fig. 5 and Fig. 6, wherein, Fig. 5 is the normally-open state diagram of valve, and Fig. 6 is valve normal switching-off
State diagram.The normally-open course of work of the burnt gas valve is：When button 2211 is lifted, button spindle is driven by carrying button 2211
222, epithelium 2243 is driven by button spindle 222, move up.Due to epithelium 2243 drive control-rod 225 on V-groove 2251 to
Upper movement so that movable axis 2252 moves to the V-type tip of V-groove 2251, spring 213 is opened and closed by 215 times compressions of motion bar,
So that sealing valve port pad 211 and the valve port 212 of the dynamic left end of motion bar 215 are separated, now valve port 212 is turned on.
Lift after button 2211 decontrols, due to back-moving spring 2212 in the presence of, can make to carry button 2211 and reset.Now, then
With the big magnet 303 of hand propelled depart from the first armature 302 and along the adhesive of 304 and second armature of hand-operated valve pipe 305 after, big magnet
303 with small magnet 308 in the presence of homopolarity mutually repels, the strength compression power assistant spring of magnet frame 309 is driven by small magnet 308
310, now outlet valve pad 307 and sealing plane 306 separate, gas outlet 112 turns on.
The course of work of shutoff valve door under normal operating conditions：When pipeline is in normal work, when closing valve,
First button spindle 222 is pressed, drives epithelium 2243 to move down, drive control-rod 225 to move down by epithelium 2243.Now, V
The movable axis 2252 of the inside of type groove 2251 can move to the top of V-groove 2251.Motion bar 215 is driven to the right by movable axis 2252
It is mobile, now by the effect of keying spring 213 so that sealing valve port pad 211 is dead with the closing patch of valve port 212.Afterwards, by outlet
Big magnet 303 at mouthful moves to left, due to the mutually repulsion with small magnet 308, the phase right of small magnet 308 can be promoted to move,
Outlet valve pad 307 is mutually adjacent to sealing plane 306, gas outlet is closed.
Fig. 7 is referred to, it is gas valve internal low-voltage or the structural representation without pressure.When the air pressure mistake of the lower section of epithelium 2243
When low, when being less than the pressure of the top of epithelium 2243 by the pressure that the lower section of epithelium 2243 is born, epithelium 2243 can drive control
Bar 225 is moved down, and the movable axis 2252 of the inside of V-groove 2251 can move to the top of V-groove 2251；Now, bullet is being opened and closed
In the presence of the elastic force of spring 213, the sealing valve port pad 211 and valve port on the strength promotion motion bar 215 of spring 213 one end are opened and closed
212 closing notes are dead, so as to cut off source of the gas.
It is automatically switched off due to low-pressure state in valve, and when pipeline recovered normal supply, reopens valve
Men Shi, can lift button 2211, and button spindle 222 is driven by carrying button 2211, and epithelium 2243 is driven by button spindle 222, move upwards
It is dynamic.Because epithelium 2243 drives the V-groove 2251 on control-rod 225 to move up so that movable axis 2252 moves to V-groove
2251 V-type tip, spring 213 is opened and closed by 215 times compressions of motion bar, so that the sealing valve port of the dynamic left end of motion bar 215
Pad 211 is separated with valve port 212, and now valve is opening.
Fig. 8 is referred to, it is the structural representation of gas valve inside super-pressure.When manifold pressure is too high, due to skin
The pressure that the lower section of film 2243 is born is excessive, can move up, and drives button spindle 222 to move up, now on button spindle 222
Boss 2233 can be pushed up holds thimble 2232, and boss 2233 can move to the top of thimble 2232, and now thimble 2232 can be in resistance bullet
In the presence of spring 2231, the lower section of boss 2233 is blocked.At the same time, the V-groove 2251 of control-rod 225 can be moved up, from
And the movable axis 2252 in V-groove 2251 is moved down, now open and close the strength of spring 213 and promote the valve port of the one end of motion bar 215 close
Packing 211 is dead with the closing note of valve port 212, so as to cut off source of the gas.
When valve is in high pressure and is automatically switched off, when pipeline recovered normal supply, button can be pressed
Bar 222, the boss 2233 on the button spindle 222 can push up the thimble 2232 on the both sides for holding the lower section of boss 2233, move down.Pass through
Button spindle 222 is pressed downward epithelium 2243, drives control-rod 225 to move down by epithelium 2243；Now, movable axis 2252 is in V-type
The tip of the V-groove 2251 can be moved in groove 2251.Spring 213 is opened and closed so as to drive motion bar 215 to compress, and makes motion bar
The sealing valve port pad 211 of 215 left ends and valve port 212 are separated, and now, valve is opening.
The present invention can have various deformation implementation method, such as by the tip of V-groove 2251 set on control-rod 225
One end of gas outlet 112 is pointed to, the sealing valve port pad 211 is arranged on the inside of valve port passage.
The invention is not limited in above-mentioned implementation method, if not departing from the present invention to various changes of the invention or deformation
Spirit and scope, if these are changed and within the scope of deformation belongs to claim of the invention and equivalent technologies, then this hair
It is bright to be also intended to comprising these changes and deform.
