See Fig. 1, a kind of automatic temperature-control gas safety valve comprises valve body 1, solenoid valve 2, manual switchgroup 3, switch dynamical element 4, it is characterized in that being provided with in the valve body air-inlet cavity 11, the spool chamber 12, the storing cavity 13 of giving vent to anger, the outlet chamber 14 that are communicated with successively; Air-inlet cavity is provided with suction port 15, and outlet chamber is provided with air outlet 16, and spool chamber is provided with ever-burning flame air outlet 17; Be provided with the solenoid valve diaphragm seal 21 of controlling both break-makes between air-inlet cavity and the spool chamber, the solenoid valve diaphragm seal is connected with solenoid valve 2 in being arranged on air-inlet cavity; Be provided with the spool 5 of control spool chamber and give vent to anger storing cavity, ever-burning flame air outlet break-make in the spool chamber, spool is connected with manual switchgroup; Give vent to anger and be provided with first connected element 61 of both break-makes of control between storing cavity and the outlet chamber, the first connected element lower end is connected with second connected element 62, the second connected element lower end is connected with mobilizable the 3rd connected element 63, switch dynamical element 4, the second connected elements that the 3rd connected element connects its motion of control are supported by the primary seal spring 620 that is arranged on the outlet chamber bottom; Be provided with small flow passage 610 in first connected element, the second connected element inside is provided with the small flow sealed member 7 of control small flow passage break-make, have vent 624 on second connected element and communicate with outlet chamber, the small flow sealed member is connected with the 3rd connected element by spring sheet 630.
Course of action of the present invention is as follows:
1, buttoned-up status
See that Fig. 1, suction port have combustion gas to enter, but cut off air-flow by the solenoid valve diaphragm seal between air-inlet cavity and the spool chamber, cut off air-flow by spool between the spool chamber and the storing cavity of giving vent to anger, the ever-burning flame air outlet, give vent to anger and cut off air-flow by first connected element between storing cavity and the outlet chamber, the small flow passage cuts off air-flow by the small flow sealed member.
2, connect the ever-burning flame air outlet
See Fig. 2, operation manual switchgroup, manual switchgroup control spool rotates counterclockwise 50 degree, connects spool chamber and ever-burning flame air outlet; Open solenoid valve simultaneously, solenoid valve drives the action of solenoid valve diaphragm seal, connects air-inlet cavity and spool chamber; So, connect the ever-burning flame air outlet.G among the figure represents combustion gas.
3, connect the storing cavity of giving vent to anger
See Fig. 3, operation manual switchgroup, manual switchgroup control spool rotates 90 degree counterclockwise again, connects spool chamber and gives vent to anger storing cavity.G among the figure represents combustion gas.
Enter temperature automatically controlled state this moment, and the conducting of give vent to anger storing cavity and outlet chamber is finished by first connected element, second connected element, the 3rd connected element, small flow sealed member.
4, connect little airflow
The switch dynamical element is to detect ambient temperature when lower than setting temperature, just starts safety valves for gas work, is maintained to certain level to guarantee ambient temperature.When the switch dynamical element detects ambient temperature is to prescribe a time limit on the setting temperature, and the storage bin of giving vent to anger is in closed condition, the give vent to anger storage bin and the not conducting of storehouse of giving vent to anger.
See Fig. 4, when the switch dynamical element detects ambient temperature when spending less than the setting temperature upper limit 5, the switch dynamical element is made contractive action, driving the 3rd connected element down moves, the 3rd connected element no longer withstands spring sheet, makes spring sheet ineffective power of moment, makes rebound rapidly; Spring sheet no longer withstands the small flow sealed member, the small flow sealed member falls, the small flow sealed member loses seal action rapidly, the small flow passage is opened, communicate with outlet chamber because second connected element is inner, so little airflow is connected to the air outlet, the flow that makes the air outlet is that (15% state is to be that product uses different source of the gas (petroleum gas for 15% state of design load, rock gas, artificial gas) and be disposed at different types and set, because the requirement of the initial calorific value of its gained had difference when product used different sources of the gas and type, 15% state is designed to adjustable, make product can extensively apply on the fuel gas heating apparatus and gas burning roastor of different type of machines, thereby popularize).G among the figure represents combustion gas.
At this moment, first connected element, second connected element still are subjected to the active force of primary seal spring, are in complete sealing state, and main air flow is not opened, and little fire is in burning so safety valves for gas is.
5, connect main air flow
See Fig. 5, when the switch dynamical element detected ambient temperature and still do not reach the minimum of setting temperature, the switch dynamical element continued to do contractive action, drove the 3rd connected element and continued down motion; Because the 3rd connected element and second connected element are to flexibly connect, the 3rd connected element continues down to move behind the 0.5mm, at this moment beginning to drive second connected element down moves, second connected element drives first connected element and down moves, thereby first connected element is no longer sealed and is given vent to anger between storing cavity and the outlet chamber, open the main flow passage fully, main air flow is discharged by the air outlet, realizes big fire burns.G among the figure represents combustion gas.
Otherwise when temperature rose, the switch dynamical element was made turgor movement, and at first first connected element, second connected element are subjected to the reaction force of primary seal spring, and up motion will be given vent to anger and be closed between storing cavity and the outlet chamber; Give vent to anger close between storing cavity and the outlet chamber after.The switch dynamical element is still expanding, make the 3rd connected element continue rising 0.5mm after, top upper spring sheet makes spring sheet at the moment small flow sealed member of upspringing, the small flow sealed member is sealed the small flow passage, thereby valve body is closed automatically.
