Abstract
The utility model provides a household combustion-gas cutting-off automatic protector, mainly comprising a gas supply on-off device, a gas-pressure chamber 5 which is formed by an intake tube 15, a gas inlet tube 11 and a tympanic membrane 10 and a transmission rod 8 in which the tympanic membrane 10, and a tympanic membrane are connected integrally. In the automatic protector, the gas pressure energy of the combustion-gas is used to complete integral automatic protection, and the utility model has the advantages of simple structure and convenient operation. The utility model is both a household combustion-gas cutting-off automatic protector, and a switch, being very suitable for the arrangement of natural gas or the household use of the gas.
Description
The utility model provides a kind of automatic safe protective device that leaks gas that stops that is used for natural gas, the use of coal gas family.
In the use of natural gas, coal gas, sometimes air feed can occur undesired, the air feed end air feed again of stopping the supple of gas or steam sometimes.Plastic cement pipe joint on the fire door comes off because of being heated sometimes, if unmanned or unattended in this moment man, common air cock can not be closed the air feed gas circuit automatically.Can occur the gas poisoning or the problem of catching fire like this, user's life and family's property just incur loss.And present used combustion gas protective device utilizes electromagnetic action to finish automatic protection, when contingency power failure or calutron no current, does not just have protective effect.
The purpose of this utility model provides a kind of family expenses combustion gas automatic safety device without external power source power, to guarantee automatically the air feed gas circuit to be closed the reliability and stability of raising safeguard protection when combustion gas is stopped the supple of gas or steam.
The utility model is to realize like this; on this protector; include the air supply valve device; the air-pressure chamber that air inlet pipe, escape pipe, eardrum and three form is arranged at the bottom in the shell; eardrum top is fixed with transmission rod; transmission rod and lever hook are installed together, and are connected on the support in the middle of the lever hook, and the other end and peg are installed together.Handle and peg are fixed on the air supply valve, between air supply valve and support spring are arranged.
Like this, when the air feed end is stopped the supple of gas or steam or because the plastic cement pipe joint on the fire door comes off because of being heated when leaking gas, and air-pressure chamber loses air pressure, therefore eardrum falls, thereby drive transmission rod and then the drive air supply valve is closed the air feed end.
Adopt the family expenses combustion gas of the said structure automatic protector of stopping the supple of gas or steam,, do not need electric power or other power, improved the reliability and stability of safeguard protection owing to be to utilize the air pressure of combustion gas itself to do work to finish automatic protective effect.
Below in conjunction with description of drawings concrete structure of the present utility model and operation principle.
Fig. 1 is the schematic diagram of concrete structure of the present utility model.
As shown in drawings; on the family expenses combustion gas of the utility model is stopped the supple of gas or steam automatic protector; comprise the air supply valve device; the air-pressure chamber (14) that the interior bottom of shell (17) has air inlet pipe (15), escape pipe (11), eardrum (10) and three to form; eardrum top is fixed with transmission rod (7); transmission rod and lever hook (5) are installed together, and are connected on the support (4) in the middle of the lever hook, and the other end and peg (1) are installed together.Handle (16) is fixed on the air supply valve (2) with peg (1), between air supply valve (2) and support (4) spring (3) is arranged.
Between eardrum (10) and air pressure by-pass cock (8), spring (9) is arranged, form barometric control unit; Eardrum (10) bottom is connected with push rod (13), and decompression lever (12) is installed together with push rod, forms decompressor.
When air supply valve was in open mode, peg (1) and lever hook (5) were stuck.As there being combustion gas (natural gas, coal gas) just can enter escape pipe (11) in the air inlet pipe (15) through air-pressure chamber (14), and normal the use.Stop the supple of gas or steam or be connected on plastic cement pipe joint on the fire door when air inlet pipe and come off because of being heated when leaking gas, air-pressure chamber loses air pressure, eardrum thereby move down, move down thereby drive transmission rod, the lever hook breaks away from peg under the effect of transmission rod, under the effect of extension spring (3), air supply valve is closed, air inlet pipe is closed, and as air feed end air feed again, combustion gas can not be passed through.
When the needs air feed, rotatable handles (16) is stuck peg (1) and lever hook (5) again, and air supply valve is opened, and finishes air feed.At this moment eardrum with on move.
On lift and move down air pressure adjustment switch (8), the bayonet socket above it is stuck on the shell (17), change the spring predetermined elastic force, can realize the adjusting of air pressure.
Pressure when air pressure is too high in the air-pressure chamber moves eardrum on further, and at this moment the push rod (13) that connects together with eardrum drives decompression lever (12) and moves to inlet end, and barrier air flows, and stream pressure is reduced, and air-pressure chamber pressure just can decrease.
When in use, if when stove fire closed, can press hand switch button (6), the lever hook other end is lifted, peg and the disengaging of lever hook, air supply valve just can be closed.
Claims (2)
1, the family expenses combustion gas automatic protector of stopping the supple of gas or steam; comprise the air supply valve device; it is characterized in that; on described protector; the air-pressure chamber (14) that the interior bottom of shell (17) has air inlet pipe (15), escape pipe (11), eardrum (10) and three to form, eardrum top is fixed with transmission rod (7), and transmission rod and lever hook (5) are installed together; be connected on the support (4) in the middle of the lever hook, the other end and peg (1) are installed together.
2, the family expenses combustion gas as claimed in claim 1 automatic protector of stopping the supple of gas or steam; it is characterized in that; on described air supply valve device, handle (16) is fixed on the air supply valve (2) with peg (1), between air supply valve (2) and support (4) spring (3) is arranged.
