Abstract
The utility model relates to a high pressure proof gas meter which can cut off a gas circuit automatically in case of overpressure gas supply in a duct. An entrance valve base is provided at a gas inlet of the meter; a connecting rod having a hand resetting button is threaded on the sidewall of an enclosure of the meter. The front end of the connecting rod extends into a chamber of the valve base, and is connected with a rubber closing plate. A pressure valve is enclosed on the connecting rod. Magnets are provided on the outer wall of both sides of the pressure valve body. A rubber diaphragm and an armature, which are integrated, are provided in the valve body. The armature is permanently connected with the body of the connecting rod coaxially. In case of overpressure of gas in the duct, force is exerted on the rubber diaphragm inside the pressure valve, the rubber diaphragm drives the connecting rod and the rubber closing plate to move, the gas circuit is shut off to protect the gas meter; after supply gas pressure gets right, the gas meter is turned on by operating the hand resetting button.
Description
Affiliated technical field
The utility model belongs to measurement of gas flow Instrument technology field, relates to a kind of anti-high-pressure gas table that can cut off gas circuit when superpressure air feed situation appears in pipe gas automatically.
Background technology
Pipe gas used in everyday, pressure approaches normal pressure, so the gas meter, flow meter of user installation also all can only use in the normal pressure scope at present.Because the pressure during gas supply, all be to be defeated by the user again after transferring low pressure to by high pressure, in case voltage-regulating system breaks down, cause high-pressure gas to enter the user, will make gas meter, flow meter gently then damaged or measure inaccurate, heavy then generation table body blast causes a large amount of leakages of combustion gas and causes the security incident generation.
The utility model content
The purpose of this utility model is according to the existing existing deficiency of gas meter, flow meter; provide a kind of structural principle simple and practical and can under the superpressure state, realize the automatically anti-high-pressure gas table of protection; this gas meter, flow meter can cut off the inlet gas gas circuit immediately when air feed generation superpressure, thereby effectively protects the safety of user and Biao.
Be used to realize that foregoing invention purpose technical solution is such: the anti-high-pressure gas table that is provided is by the watchcase main body of bringing gas port and gas outlet into, air bag and tolerance counter are formed, air intake opening place at table is provided with a port valve seat, the watchcase main body near the side shell wall of air intake opening on ecto-entad be equipped with the connecting rod that the hand button that resets is equipped with in a rear end, the front end of connecting rod feeds in the valve support chamber and connects a valve port rubber shrouding is housed, be set with a pressure valve at the connecting rod body of rod near watchcase inner wall position place, said pressure valve has the shell frame shape valve body that a both sides outer wall is equipped with magnet, the magnet of one side is fixed on the watchcase main body and resets on the hand button end housing wall, be provided with a rubber diaphragm and an armature that is connected with the rubber diaphragm one in valve body, armature is coaxial affixed with the body of rod of connecting rod.User installation behind this gas meter, flow meter, at supply gas pressure just often at ordinary times, suffered insufficient pressure on the rubber diaphragm in the pressure valve is so that armature breaks away from the attractive force of the non-hand button end magnet that resets, at this moment, the rubber shrouding mouth of lifting off a seat, gas circuit is unimpeded, and the user can normally use combustion gas; When supply gas pressure raises; install with the pressure valve of showing in the body and detect the pressure rising; when pressure is increased to setting value; rubber diaphragm in the pressure valve is stressed to be made armature shake off the non-attractive force that resets hand button end magnet to move to other direction; causing being located at the reset magnet of hand button end attracts; at this moment; valve seat is closed gas circuit by the rubber shrouding of the coaxial connection of rubber diaphragm; make the gases at high pressure in the pipeline can not enter in the gas meter, flow meter; thereby protected the safety of gas meter, flow meter, gas meter, flow meter is not damaged by gases at high pressure.After in case pressure valve is closed, must treat supply gas pressure recover normal after, can open gas meter, flow meter once more by the manual operation hand button that resets.
Compared with prior art; of the present utility model rational in infrastructure, easy to operate; cut off the design proposal of system by in traditional gas meter, setting up pressure sensitive; protection gas meter not reason overpressure of gas and the effect that damages have been realized; guaranteed vast combustion gas user's the safe gas of using, practicing of its product has favorable social and economic benefits.
Description of drawings
Accompanying drawing is the structural representation of a specific embodiment of the utility model.
Embodiment
As shown in drawings, air intake opening 8 places in gas meter, flow meter watchcase main body 12 are provided with a port valve seat 1, be built-in with a reciprocating rubber shrouding 10 that is used to cut off the gas passage at valve seat, rubber shrouding 10 is connected with an end of connecting rod 2, the other end of connecting rod 2 passes shell wall and is connected with the hand button 4 that resets, being set with one at connecting rod 2 bodies of rod near watchcase inner wall position place can open, the pressure valve 7 of closing, a secondary permanent magnet 5 and 9 respectively are equipped with in 7 liang of lateral wall places of pressure valve, wherein magnet 5 is fixed on the hand button end housing wall that resets of watchcase main body 12, in pressure valve 7, be provided with rubber diaphragm 6, rubber diaphragm 6 centers are equipped with armature 3, and the center of rubber diaphragm 6 and armature 3 is all coaxial to be installed on the connecting rod 2.During normal condition, attracted by magnet 9 with the rubber diaphragm 6 coaxial armature that are connected 3 in the pressure valve 7, at this moment, the rubber shrouding 10 in valve seat the place ahead lifts off a seat 1, and it is unimpeded that gas circuit keeps, and the user can just use gas always; When supply gas pressure generation superpressure; rubber diaphragm 6 suffered power in the pressure valve 7 make armature break away from the attractive force of magnet 9; move to other direction; the connecting rod 2 of coaxial connection drives armature 3 and also is moved; when near magnet 5 time, attracted by magnet 5, the rubber shrouding 10 of coaxial connection blocks valve seat 1 the import gas circuit is closed; at this time the gases at high pressure in the air intake opening 8 can not enter gas meter, flow meter inside, have protected gas meter, flow meter can not blast.
In the specific implementation process, the interchangeable setting of the armature of pressure valve 7 and magnet in the foregoing description structure, promptly respectively be provided with an armature at pressure valve 7 both sides outer walls, the armature of one side is fixed on watchcase main body 12 and resets on the hand button end housing wall, in valve body, be connected with rubber diaphragm 6 one and with the coaxial affixed magnet that is of connecting rod 2 bodies of rod.
