Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, 2, combustion gas dropping valve safety alarm, it comprises magnet steel 1, magneto-dependent sensor 2, checks control circuit 6 and alarm 7; Described magnet steel 1 is installed in the hard-core 3 of combustion gas dropping valve or is installed on the valve rod 5 with diaphragm 4 interlock of combustion gas dropping valve, the outside that is installed in the combustion gas dropping valve that magneto-dependent sensor 2 and magnet steel 1 are relative, the output terminal of magneto-dependent sensor 2 links to each other with the corresponding input end of checking control circuit 6, checks that the alarm signal output ends of control circuit 6 links to each other with the signal input part of alarm 7.
Combustion gas dropping valve of the present utility model comprises dropping valve body, spring 8, hard-core 3, diaphragm 4 and valve rod 5, described dropping valve body is provided with inlet hole 9 and air outlet hole 10, one end of spring 8 links to each other with the top of dropping valve body, the other end links to each other with hard-core 3, the middle part of diaphragm 4 is installed in the hard-core 3, the two ends of diaphragm 4 embed the dropping valve body, and the base of valve rod 5 is installed on the dropping valve body, an end of valve rod 5 and hard-core 3 interlocks.
The utility model comprises also that by battery 11 battery 11 provides working power for the combustion gas dropping valve with safety alarm.
During concrete enforcement:
Fix a magnet steel or magnet in dropping valve and the valve rods 5 diaphragm 4 interlock, magneto-dependent sensor is laid in outside at dropping valve, the output of magneto-dependent sensor connects checks control circuit, check that the control circuit output alarm signal to having sounding or luminous, alarm luminous and that deposit takes place perhaps; Along with valve body interior diaphragm 4 moves up and down, drive magnet steel or magnet and move up and down, thereby it is moving that magneto-dependent sensor is produced, make to produce signal, check that control circuit is checked through signal, send action, the output control signal drives alarm sounding or light.
After opening total gas valve, the gas that comes out from cylinder of steel or pipeline enters the film chamber below the diaphragm 4, and diaphragm 4 tops have a spring 8 to be pressed in above the diaphragm 4, and diaphragm 4 links to each other with a valve rod 5 simultaneously.When the gas pressure in jar was too high, gas was diaphragm 4 jack-up, and diaphragm drives L shaped valve rod 5 simultaneously, as shown in Figure 1.Or the diaphragm 4 direct valve rods that drive upwards push away as Fig. 2; Diaphragm 4 slowly upwards shipper pole ovable valve stem 5 gas-entered passageway is diminished, put the passage that little gas enters the film chamber, the resistance that gas enters the film chamber increases, and the indoor gas pressure of film is diminished; Also drive magnet steel at the same time or magnet leaves the origin-location, make outside magneto-dependent sensor state change, check that control circuit is checked through the magneto-dependent sensor state and changes, viva voce prompting and light are pointed out; When the pressure that enters gas when inlet hole diminished, diaphragm moved down, and drives valve rod and makes inlet hole become big as Fig. 1; Or the drive valve rod diminishes the inlet hole change greatly as Fig. 2 air resistance; The pressure of film indoor gas can become greatly, to keep entering into the gas pressure of pipe; Drive magnet steel or magnet are got back to original position when diaphragm 4 moves down at the same time, and the magneto-dependent sensor state resets, and check that control circuit is checked through the magneto-dependent sensor state and changes, and stop voice prompt and prompting light.
Using combustion gas place (for example: the kitchen range top, welding rifle) to be under the closed condition; Pressurized gas enter in the step-down valve pocket after opening total gas valve, and testing circuit is sounded, and close total gas valve then, and the pipeline serviceable condition is sent prompt tone or prompting light always; Pipeline has leakage, and along with valve pocket internal air pressure and barometric pressure balance, magnet steel or magnet are got back to original position, and the magneto-dependent sensor state resets, and checks that control circuit is checked through the magneto-dependent sensor state and changes, and voice prompt and light will disappear.
The circuit part working procedure, when dried magnet or magnet steel near magneto-dependent sensor the time, magneto-dependent sensor is on state, and when magnet or magnet steel away from magneto-dependent sensor the time, magneto-dependent sensor is in off state.So just produced two states, checked control circuit to be SCM system (or logical circuit etc.) according to state produce and be in an emergency or point out.As shown in Figure 3, check the control circuit of control circuit for the band SCM system; As shown in Figure 4, check that control circuit is the simple trigger control circuit.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
