Embodiment
As shown in figure 1, the combustion gas high-pressure and overflowing stop valve is connected to the inlet end of gas pressure regulating valve, when gas pressure regulator, governor,
When burner switch goes wrong or leakage occurs and causes the flow to become big suddenly for combustion gas tracheal rupture, combustion gas high-pressure and overflowing stop valve closes
Close, so as to cut off the supply of combustion gas, ensure the safe handling of combustion gas.
As shown in Fig. 2 the combustion gas high-pressure and overflowing stop valve includes valve body 1, valve body 1 has air inlet 10 and gas outlet
11, gas outlet 11 is just connected on gas pressure regulating valve, has valve element and valve seat 12 in valve body 1, and valve element is located at valve seat 12 towards entering
The side of gas port 10, the valve element include valve element（Steel ball）2 and flow control assembly, flow control assembly include control piece
3 are connected to control piece 3 towards one end of air inlet 10, other end fixed setting with extension spring 4, one end of the extension spring 4（Specifically will
Extension spring 4 is connected on valve core frame 40, and valve core frame 40 is fixedly mounted in valve body 1, and the extension spring 4 can also be connected directly between valve body 1
On inwall, as long as this one end of extension spring 4 is fixed）, valve element 2 is arranged on control piece 3 towards one end of gas outlet 11, and controls
Part 3 has the flow piece 30 to match with the inner chamber of valve body 1（Here matching refers to that the diameter of flow piece 30 is slightly less than in valve body 1
The internal diameter of chamber, flow piece 30 can in valve body 1 intracavitary normal movement）, as shown in figure 4, flow piece 30 is provided with metering orifice 32.
When flow is normal, metering orifice 32 of the combustion gas through inflow-rate of water turbine piece 30, then combustion gas is entered by the through hole of valve seat 12
Pressure regulator valve, in this case, extension spring 4 haul control piece 3, control piece 3 is in a kind of poised state, now on control piece 3
Valve element 2 be at normal state of ventilation away from valve seat 12, such stop valve；And when gas flow exceedes threshold values, control
The balance of part 3 is broken, and in the presence of combustion gas, control piece 3 moves to the direction of valve seat 12, as shown in figure 3, on control piece 3
Valve element 2 is just acted on valve seat 12, forms sealing, thus cuts off the supply of combustion gas.
When source of the gas pipeline recovers normal, it is necessary to reset control piece 3, before this, due to the presence of air pressure, valve element 2
Still act on valve seat 12, want to make stop valve recover open mode, it is necessary to valve element 2 is divided with valve seat 12 by external force
From.Therefore, control piece 3 of the present utility model also has support 31, the support 31 is made up of several supporting ribs 310, by
There is larger space between supporting rib 31, therefore resistance will not be formed to the circulation of combustion gas in normal ventilation, exist in addition
31 outer movable sleeve of support is provided with the flux sleeve 5 to match with the inner chamber of valve body 1（Here matching refers to that the diameter of flux sleeve 5 omits
Less than the internal diameter of the inner chamber of valve body 1, such flux sleeve 5 can in valve body 1 intracavitary normal movement）, and it is arranged with work outside valve body 1
Dynamic set 6, the inwall of the movable sleeve 6 is provided with magnet ring 7.During recovery, if by the movable sleeve 6 outside valve body 1 lightly along inverse gas
Stream direction one pushes away（I.e. along the direction of air inlet 10）, due to the effect of magnetic force, magnet ring 7 moves with the flux sleeve 5 in moving valve 1, by
In the supporting of support 31, flux sleeve 5 can steadily be moved on support 31, will not diametrically shaken；Work as magnetic conduction
Set 5 is acted on flow piece 30, and control piece 3 can be made to be moved to the direction of air inlet 10 of valve body 1, so that valve element 2 leaves
Valve seat 12.Work as depressurization, control piece 3 recovers original poised state again, and hereafter gas-cooker just can normal use.
In order that the use of combustion gas high-pressure and overflowing stop valve is more convenient, while ensure that safety valve is all the time under normal ventilation
In open mode, the utility model is provided with stopper slot 9 in the outer wall of valve body 1, and magnet ring 7 protrudes from the inwall of movable sleeve 6, and
It is movably disposed in the stopper slot 9, is provided with spring 8 in stopper slot 9, the one end of spring 8 is acted on the side of magnet ring 7, separately
One end is acted in stopper slot 9 in the side wall of air inlet 11.It is living due to the active force of spring 8 under normal operating condition
Magnet ring 7 on dynamic set 6 is in one end away from air inlet 10 all the time in stopper slot 9, now the flux sleeve 5 in valve body 1 also with
With magnet ring 7 away from flow piece 30；When needing to reopen after the closing of combustion gas high-pressure and overflowing stop valve, as long as movable sleeve 6 is dialled
To the end of air inlet 10, after combustion gas high-pressure and overflowing stop valve is opened, movable sleeve 6 is with magnet ring 7 and under the active force of spring 8
Automatically recover original state, so facilitate the operation of high-pressure and overflowing stop valve.
