The gas self-control safety valve has three functions of stopping, stopping gas, self-closing and explosion-proof, is convenient to install and use, and is an ideal safe energy-saving product for families, enterprises and institutions.
Description
The utility model relates to the poppet valve that has the barrier film stopper, specifically a kind of combustion gas autocontrolled safety valve that is widely used in pipeline natural gas, coal gas, liquefied petroleum gas (LPG), biogas.
Gas pipeline closes mainly by the valve manual-lock on the gas ring at present, when just using gas on the cooking stove during air feed line failure, air feed stops, flame can extinguish suddenly, as nobody finds not throttle down before the kitchen range, when air feed line fault is got rid of once more air feed, will cause combustion gas to leak, the carbon monoxide piped gas will cause casualties after surpassing finite concentration in this way, and naked light meeting breaking out of fire or blast are met in other combustion gas in this way, and consequence is hardly imaginable.A kind of " combustible gas pipeline safety shutoff " by name once disclosed for Chinese patent CN2146622Y number, its formation is based on mitre velve, have one to add long bolt in valve body lower end, be with spring support on the screw rod, the high pressure nut, on the valve rod in valve body lower end hole, be fixed with a connecting body, its bottom surface is fixed with little just as step reducing motor and position limit switch, and motor shaft and long bolt join, and a horizontal depression bar is arranged on the motor shaft, when combustible gas is revealed in the room, alarm circuit is connected and is sent chimes of doom, and shut-off circuit is switched on, and motor rotates valve rod, with closedown of pipeline, this patent structure complexity runs into power-off condition and just can't close pipeline automatically, stops combustion gas to leak.
The purpose of this utility model is for fear of above-mentioned deficiency of the prior art, and provides a kind of simple in structure, and is easy to use, have by, stop the supple of gas or steam self-closing and close fire-proof and explosion-proof combustion gas autocontrolled safety valve automatically.
The purpose of this utility model can reach by following measure:
A kind of combustion gas autocontrolled safety valve, comprise respectively with valve body 1 on the bonnet 2 and the bottom flange 3 that are connected, its special way is, diaphragm 8 between bonnet 2 and the valve body 1 is assemblied in valve rod 10 middle parts that have spring 18 by nut 12 and chuck 11, valve rod 10 bottoms that have spring 14 are equipped with sucker 6, valve body 1 one sides are provided with admission line 17, and stopping the supple of gas or steam to close with the cone gate head 7 that has sucker 6 with the fixing iron core 5 that wraps up magnet ring 4 of outlet pipe 18 outer walls between the valve body 1 at bottom flange 3 cooperates.
Can be provided with dish-shaped clamping plate 9 between nut 12 of the present utility model and the diaphragm 8.
Can be provided with little spring 14 in the sucker of the present utility model.
Accompanying drawing and description of drawings:
Accompanying drawing is the utility model cross-sectional view.
Among the figure: 1-valve body, 2-bonnet, 3-bottom flange, 4-magnet ring, 5-iron core, 6-sucker, 7-valve head, the 8-diaphragm, 9-clamping plate, 10-valve rod, 11-chuck, 12-nut, 13-handle, the 14-little spring, 15-seal ring, 16-spring, 17-admission line, 18-outlet pipe, 19-small boss.
The utility model further specifies embodiment below in conjunction with accompanying drawing:
Be combustion gas autocontrolled safety valve cross-sectional view as shown in drawings, valve body 1 and bonnet 2, bottom flange 3 are aluminium die casting product, connect with bolt between the three, accompany the diaphragm 8 that thin rubber is made between bonnet 2 and the valve body 1, the valve rod 10 that has spring 16 passes the diaphragm centre and with nut 12 and dish-shaped clamping plate 9 diaphragm is fixed on the chuck 11 of band seal ring, with anti-gas-leak.Valve rod 10 bottoms that are positioned at valve body 1 are equipped with little spring 14, and are wrapped in the sucker 6, it be used for guaranteeing the certain and sealing force of sealing force flexible automatically mend long, at cushion rubber aging or be out of shape after guarantee reliable sealing.Block inlet hole when preventing that sucker from moving upward, on sucker 6, be cast with small boss 19.Valve body 1 one sides are provided with admission line 17, the cavity a that is attached thereto communicates with the cavity c at diaphragm 8 lower cavity b and outlet pipe 18 places, outlet pipe 8 outer walls between bottom flange 3 and valve body 1 overlap cored 5, iron core 5 is with permanent magnet ring 4, valve rod end tapered valve head 7 moving up and down is stopped the supple of gas or steam to close automatically with iron core 5 and is cooperated, and is furnished with rubber seal 15 in order to prevent gas leakage on iron core 5, manually mentions valve rod 10, when the kitchen range air feed, sucker 6 moves upward simultaneously with valve rod 10.
Lift three kinds of situations below this kitchen range function of use be described:
1) stop valve function:
The normal use when needing in kitchen range air feed, handle 13 drives valve rod 10, make its end tapered valve head 4 and sucker 6 overcome magnetic attraction and upwards open suction valve 7, coal gas enters a chamber by admission line 17, enter the c chamber to the kitchen range air feed through the b chamber, the hand of finishing using when stopping air feed driving valve rods 10 by lower handle 13 and moves downward, and the 5 pairs of irony suckers 6 of iron core that magnetized by magnet ring 4 have suction, make valve head 7 and iron core high-seal, do not have combustion gas again in the outlet pipe 18.
2) the self-closing function of stopping the supple of gas or steam:
When cooking stove just in use, gas pipeline breaks down, when dying suddenly, admission line 17 and a cavity pressure＜0.5 kPa, b cavity pressure also descend simultaneously, promote valve rod 10 by the thrust of spring 16 and move downward, diaphragm 8 and clamping plate 9 and sucker 6 all move down, when sucker 6 during near iron core 5 and magnet ring 4, by the rapid adhesive of magnetic force, cone gate head 7 is airtight with iron core 5; If pipeline fault is got rid of, when a chamber had rebulid pressure, sucker 6 can not opened by iron core 5 and magnet ring 4 adhesives, the b cavity pressure raises, diaphragm 8 promotes clamping plate 9 pressure springs 16 and moves up, but outlet pipe is manually opened until the user owing to the suction of magnet can not opened.
At the steam line gas-cutting-off period that breaks down, when the user mentioned handle 13, because a chamber and b chamber do not have pressure, valve head 7 moved down automatically all the time under spring 16 and magnetic force and closes, and the valve of promptly not opening when the air feed of a chamber again, just recovers proper functioning.
3) close explosion prevention function automatically:
The air feed sebific duct catches fire before kitchen range, and cause when combustion gas is leaked in a large number, discharge area, c chamber in the outlet pipe 18 greater than a chamber to discharge area, b chamber, the decline of b cavity pressure, spring 16 and magnetic strength power move down diaphragm 8 and clamping plate 9, when sucker 6 during near iron core 5 and magnet ring 4, under magnetic force, valve head 7 is by fast and iron core 5 adhesives, close outlet pipe 18, thereby reach the automatic burst-preventing function.
The utility model compared with prior art has following advantage:
1, automatic control safety vavle for gas have cut-off, self-closing, the autoshutdown explosion-proof three of stopping the supple of gas or steam Big function ensures that huge numbers of families use safely gas, stops the generation of human casualty accident.
2, the utility model is simple in structure, in installation site and size and the former air supply system Valve is identical, easy to use before the used kitchen range.
