Embodiment：
Refering to Fig. 1, Fig. 2, Fig. 3, Fig. 4, gas valve of the invention includes cross one another gas circuit chamber 2 in valve casing 1, valve casing and rotation
Fill in the seal grease smeared between chamber 3, the cock 4 in cock chamber 3, cock 4 and valve casing 1, be assemblied in cock towards shell
Compression spring 6 between the knob 5 of outer one end, knob and cock, knob therein and cock are by penetrating knob 5, cock 4
Latch 7 is assembled integrally, and cock set of knobs is attached together and fits over valve by latch 7 therein through the Cross slat hole in valve body cock cavity wall
On shell 1, improvements introduced is：Valve body overtemperature, Chao Liu latch-up protections mechanism are set up in gas circuit intracavitary, described overtemperature, super stream close
Lock protection mechanism includes：The sleeve 8 in the middle part of gas circuit intracavitary, the support 9 being fixed in sleeve, dynamic cooperation are assemblied in support axle center
It is motion bar 10 in hole, the bowl-type closure 11 for being fixed on close the tip position that the one end of cock 4 is pointed on motion bar 10, movable
Back-moving spring 12 between the bar other end and support, it is fixed on after the stretching, extension of the inlet end of gas circuit chamber 2 and pushes motion bar 10 to cock 4
Overtemperature memorial alloy helical member 13, sleeve 8 therein inwardly closed up towards cock one end to be formed with closure 11 coordinate platform
Shoulder 8-1, sleeve are fixed in gas circuit chamber 2 by the locating shoulder 2-1 in gas circuit chamber and the jump ring 14 being assemblied in gas circuit chamber, are covered
Sealing ring 15 is assembled in the annular groove of 8 outer circumference surfaces of cylinder.Motion bar 10 therein is from closure 11 to the length for the termination for pointing to cock
Degree, motion bar 10 can be touched by meeting the aperture of air passing hole 4-1 when cock 4 rotates.
For ease of stabilization of the overtemperature memorial alloy helical member after the assembling and assembling of gas circuit intracavitary, firmly, remember in overtemperature
The assembly side for recalling alloy helical member 13 and valve casing 1 adds a groove type base 16, has on base 16 and matches somebody with somebody with gas circuit intracavitary screw thread
The external screw thread of conjunction.
To purify the combustion gas into gas circuit chamber, screen pack is added between overtemperature memorial alloy helical member 13 and base 16
17。
To make overtemperature memorial alloy helical member 13 precisely be connected with motion bar, in overtemperature memorial alloy helical member 13 and activity
The cohesive end of bar 10 has motion bar connecting base 18, there is the groove 18-1 coordinated with motion bar termination on motion bar connecting base 18.
Support in sleeve and sleeve are stable, are firmly connected and obtain the ventilation section of maximum to make, sleeve and support
Shape and assembly relation are preferred：Have the radial hole 8-2 being distributed in same diametric plane on sleeve, support 9 by dististyle and with dististyle into
Three fins of one are formed, and support is by the way that radial hole 8-2 salient point is positioned in sleeve 8 on embedded sleeve on fin.
Refering to Fig. 1, Fig. 5, the action process of the present embodiment gas valve overtemperature prote is：When valve body external temperature is higher than combustion gas
Use temperature safely, overtemperature memorial alloy helical member 13 is by thermal stretching, the movable end promotion activity of overtemperature memorial alloy helical member 13
Bar 10 moves along combustion gas direction, and the passage at the closure closure shoulder of closure 11 8-1, combustion gas can not enter valve body outlet side
Mouthful.After environment temperature is recovered, overtemperature memorial alloy helical member 13 shrinks back initial length, and closure 11 remains sealed upon shoulder
At 8-1, by closing gas valve door cock button 5, when being again turned on valve, motion bar is touched in the air passing hole 4-1 of cock 4 aperture
10., under the drive of back-moving spring 12, closure 11 returns to origin-location, and burnt gas valve can be with normal use.
Refering to Fig. 1, Fig. 6, the action process of the super stream protection of the present embodiment gas valve is：Under normal operating conditions, due to multiple
The elastic force of position spring 12 acts on, and has gap between the shoulder 8-1 on closure 11 and sleeve 8, it is ensured that combustion gas is normal through use.
When gas flow reaches 2 times of metered flows, combustion gas promotes the inner side bowl face of closure 11 closure 11 is moved to shoulder 8-1,
The passage at shoulder 8-1 is blocked, combustion gas can not enter valve body air outlet.After air pressure restores, closure 11 remains sealed upon
At shoulder 8-1, by closing gas valve door cock button 5, when being again turned on valve, the air passing hole 4-1 of cock 4 aperture, which is touched, lives
