Description
Technical field
This utility model relate to safety valve for liquidefied petroleum gas improvement invention, be related specifically to the fuel gas such as various petroleum gas, liquefied gas, piped gas as the family of fuel, group, unit, the various kitchen range in kitchen gas-purification relief valve.
Background technology
In the prior art, safety valves for gas is to be provided with spool and valve core frame in valve body, and valve core frame holds spool by extension spring, valve seat is processed into horn mouth wide outside and narrow inside, when combustion gas enters valve body, and overpressure keeps balance, spool will not be formed with valve seat and seal, and valve is in the open position；When valve ahead of gas stove (or pressure regulator) is out of control, cooking stove malfunctioning switch overpressure produces pressure reduction, when having arrived limited flow rate, spool forms sealing state with spool under the influence of air pressure, namely valve is automatically switched off, it is therefore prevented that causes the poisoning or fire of the person because of gas leak, improves safety coefficient；When valve ahead of gas stove (or pressure regulator) recovers normal, just push up a bottom spool by the top in valve body, spool is made to depart from the horn mouth of valve seat, thus relief valve recovers normal operation, but in prior art, adopting relief valve in this way, still to there is top mobile dumb, relief valve operation inconvenience, overall manufactures the problems such as difficulty.
Summary of the invention
In view of known technology Problems existing, it is both safe and reliable that the purpose of this utility model aims to provide one, easy to operate, rational in infrastructure gas-purification relief valve, meet with family that various combustion gas are the energy, group, unit, kitchen all size kitchen range selection use.
Safety valves for gas of the present utility model includes valve body, described valve body has air inlet and gas outlet, there is in described valve body spool and valve seat, described spool is positioned at the valve seat side towards air inlet, it is characterized in that: in described valve body, be provided with magnetic inductive block, described magnetic inductive block is positioned at the valve seat side towards gas outlet, described magnetic inductive block has top towards the side of spool, it is arranged with movable sleeve outside described valve body, the inwall of described movable sleeve is provided with Magnet, described movable sleeve moves and Magnet can be made to move in valve body with magnetic inductive block, simultaneously the top on magnetic inductive block may pass through valve seat and acts on spool.
The outer wall of described valve body is provided with stopper slot, described Magnet highlights from the inwall of movable sleeve, and is movably disposed in stopper slot, is provided with spring in described stopper slot, described spring one end acts on the side of Magnet, and it is interior on the sidewall of air inlet that the other end acts on stopper slot.
Described valve body divides two sections, one section is made up of inlet suction port and air inlet pipe box, another section is made up of with pipe box of giving vent to anger air outlet adapter, and described air inlet pipe box threaded one end is connected to gives vent to anger in pipe box, described in the stage portion that side and the air inlet pipe of pipe box put of giving vent to anger form stopper slot.
The gas-purification relief valve that this utility model provides, compared with known technology, has the advantages such as rational in infrastructure, easy to assembly, safe and reliable, is the ideal product of energy-saving safety measure of the various kitchen range being fuel with combustion gas.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
nullAs shown in Figure 1，This safety valves for gas includes valve body，Valve body has air inlet 3 and gas outlet 1，There is in valve body spool 8 and valve seat 7，Spool 8 is positioned at the valve seat 7 side towards air inlet 3，Spool 8 is connected on valve core frame 10 by extension spring 9，Valve core frame 10 is fixedly mounted in valve body，When air pressure is normal，Spool 8 and valve seat 7 will not form sealing，And when throughput exceeds standard，Spool 8 just acts on valve seat 7，Formed and seal，Magnetic inductive block 6 it is provided with in valve body，This magnetic inductive block 6 is positioned at the valve seat 7 side towards gas outlet 1，Magnetic inductive block 6 has top 60 towards the side of spool 8，Movable sleeve 2 it is arranged with outside valve body，The inwall of movable sleeve 2 is provided with Magnet 4，Movable sleeve 2 moves and Magnet 4 can be made to move in valve body with magnetic inductive block 6，Simultaneously the top 60 on magnetic inductive block 6 may pass through valve seat 7 and acts on spool 8.
This product is mounted in valve ahead of gas stove (or pressure regulator) between exit and burner, when burnt gas switch is out of control or kitchen range pipe breakage, come off time, when its throughput exceedes regime values, relief valve overflows because of throughput, spool 8 just acts on valve seat 7 under the thrust of air-flow, now valve is just automatically switched off, and plays the effect cutting off combustion gas, has ensured the safe handling of combustion gas；When source of the gas pipeline recovers normal, as long as the movable sleeve 2 outside valve body being pushed away (namely along air inlet 3 direction) along inverse airflow direction one lightly, before this, existence due to air pressure, spool 8 still acts on valve seat 7, want to make relief valve recover open mode, it is accomplished by making spool 8 separate with valve seat 7 by external force, and the movable sleeve 2 that slides makes the Magnet 4 on movable sleeve 2 move with the magnetic inductive block 6 in moving valve, the top 60 on magnetic inductive block 6 just can be made to withstand on spool 8 through valve seat 7, so that valve is opened, work as depressurization, air pressure eliminates, spool 8 is just by extension spring 9 return, hereafter safety valves for gas recovers normal ventilation.
In order to the use making safety valves for gas is convenient, guarantee that relief valve is in open mode all the time under normal ventilation simultaneously, this utility model is provided with stopper slot 20 at the outer wall of valve body, and Magnet 4 highlights from the inwall of movable sleeve 2, and it is movably disposed in this stopper slot 20, being provided with spring 5 in stopper slot 20, this spring 5 one end acts on the side of Magnet 4, and it is interior on the sidewall of air inlet 3 that the other end acts on stopper slot 20.Under normal operating condition, due to the active force of spring 5, the Magnet 4 on movable sleeve 2 is in the one end away from air inlet 3 all the time in stopper slot 20, and now the magnetic inductive block 6 in valve body also follows Magnet 4 away from valve seat 7；When safety valves for gas needs to reopen after closing, as long as movable sleeve 2 is allocated to inlet port, after safety valves for gas is opened, movable sleeve 2 automatically recovers again original state with Magnet 4 under the active force of spring 5, so facilitates the operation of relief valve.
Produce in order to convenient and assemble, valve body is divided into two sections by this utility model, one section by inlet suction port 31(and air inlet 3 place) constitute with air inlet pipe box 30, both can be one-body molded, can also connect for removable seal, another section is by air outlet adapter 11(and place, gas outlet 1) pipe box 10 is constituted with giving vent to anger, and both can be one-body molded, it is also possible to connects for removable seal；Air inlet pipe box 30 threaded one end is connected to gives vent to anger in pipe box 10, and the side of pipe box 10 of giving vent to anger defines stopper slot 20 recited above with the stage portion on air inlet pipe box 30.By this stagewise valve body, the production making whole safety valves for gas is convenient with manufacture, and also allows for forming stopper slot 20.
Additionally it is noted that due to the magnetic field of Magnet generation, combustion gas refinement can be made, purifies, thus improve the efficiency of combustion of combustion gas, decrease the discharge of harmful gas, being finally reached the purpose of energy-saving and emission-reduction.
