Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
The utility model comprises valve body 3, the spool 5 of location, axle center is installed in valve body 3, spool 5 is made of two spacers 4 and a straight rod 8, be processed with three passages 9 on the spacer 4, be processed with on the straight rod 8 can with the semisphere valve 6 of gas outlet 7 tight connectings in the valve body 3, spring 2 one ends withstand spacer 4 central authorities of spool 5 bottoms, and the other end withstands on the valve base 1.Spool 5 can slide in valve body 3
Embodiment 1: the Fuse Type Gas safety valve
Gas safety valve and safety plate 10, the safety plate holder 12 of taking gas interface 11 out of combine and constitute the Fuse Type Gas safety valve.
The center of safety plate 10 is processed with the hole greater than straight rod 8 diameters, fuse sheet 13 is installed on the hole, be processed with three passages 14 all around, the internal thread of safety plate holder 12 matches with external screw thread on the valve body 3, safety plate holder 12 is fixed on safety plate 10 on the valve body 3, the fuse sheet 13 of safety plate 10 can back down spool 5 over against the top of straight rod 8.
During use the Fuse Type Gas safety valve is installed near gas appliance and can not be by on the gas pipeline of normal burning things which may cause a fire disaster baking.Because of safety plate 10 can back down spool 5, combustion gas will be passed through the passage 9 on valve base 1, spring 2, the spacer 4, and the gas outlet 7 of valve body 3, the passage 14 on the safety plate 10, the interface 11 of giving vent to anger flow into gas appliance.When the combustion gas abnormal combustion or extraneous on fire, when temperature exceeds normal range (NR); the Fuse Type Gas safety valve is heated; cause fuse sheet 13 melted by heat at safety plate 10 centers; spool 5 is return under the promotion of spring 2, and fuse sheet 13 is passed on the top of straight rod 8, semisphere valve 6 and gas outlet 7 tight connectings; stop up air flue; valve closing cuts off source of the gas, plays the safeguard protection effect
Embodiment 2: the decompression type Gas safety valve
Gas safety valve combines with pressure-reducing valve can constitute the decompression type Gas safety valve.
At decompression valve housing 21 inner bottom parts lever 24 is installed, lever 24 can be the axle center rotation with balance pivot 25, the transverse arm upper end of lever 24 is equipped with the sealing gasket 26 of the gas outlet 7 that can seal Gas safety valve, the perpendicular arm of lever 24 stretches in the pull bar 23, the top of pull bar 23 connects diaphragm 20 bottoms in the pressure-reducing valve housing 21, be fixed with pallet 19 on the diaphragm 20, spring 18 1 ends are pushed down pallet 19, the other end withstands the air pressure of top cover 16 belows and adjusts screw 17, start rope 15 1 ends are fixed on the pallet 19, the other end passes spring 18, and air pressure is adjusted screw 17, and top cover 16 connects draw ring 27.
During use, the decompression type Gas safety valve is installed in the gas outlet of gas pipeline or liquid gas storage tank.The pull-up draw ring 27 gently, it is up that draw ring 27 drives start ropes 15, pallet 19, diaphragm 20, pull bar 23, it is up that pull bar 23 drives lever 24, sealing gasket 26 on the lever 24 can back down the spool 5 of Gas safety valve, combustion gas will enter pressure-reducing valve by valve base 1, spring 2, spool 5, gas outlet 7, gaseous-pressure meeting jack-up diaphragm 20, diaphragm 20 drives pull bars 23, lever 24 is up.When reaching operating pressure, sealing gasket 26 can cover tight gas outlet 7, and gas appliance consumes combustion gas, the pressure-reducing valve internal gas pressure descends, and diaphragm 20 drives pull bar 23, lever 24 is descending, and sealing gasket 26 leaves gas outlet 7, combustion gas continues to enter pressure-reducing valve, so repeatedly, operate as normal.
Stop the supple of gas or steam when gas pipeline occurring; during situations such as sebific duct disengagement on the outlet nozzle 22 or abnormal combustion cause that sebific duct burns; the pressure-reducing valve internal gas pressure descends; spring 18 promotes that diaphragms 20, pull bar 23, lever 24 are descending, and sealing gasket 26 leaves gas outlet 7, and spool 5 is return under the promotion of spring 2; semisphere valve 6 and gas outlet 7 tight connectings; stop up air flue, cut off source of the gas, play the safeguard protection effect.
