Abstract

The utility model discloses a novel AQF-5 type product of combustion gas, which is used to detect the air leakage of a gas supply or a gas appliance to prevent temper, and therefore, fire and explosion can be avoided. The product is composed of an air inlet pipe, an air outlet pipe, a liquid feeding pipe, a movable valve, a buffer chamber, a liquid valve, etc. An appropriate amount of liquid is filled. The utility model can be vertically arranged between the reducing valve of the liquefied gas supply and the gas appliance through a rubber pipe.

Description

Gas burning safety device

The utility model is a kind of safety device of burning gases kitchen range, uses burn the like this user of kitchen range of liquefied gas cooker universal day by day in recent years.Because gas is easy to leakage flow, be difficult for characteristics such as observation, such as the gas leakage of liquefaction source of the gas and kitchen range, the explosion accident of catching fire that tempering etc. cause.

For solving the sorrow of this mind of people, what the utility model provided is exactly a kind of safety device that prevents the gas leakage of source of the gas, gas kitchen and prevent " tempering ".

Fig. 1 has shown the best enforcement of of the utility model device, wherein is responsible for 1 top and is connected to the gas outlet pipe 2 that is connected with sebific duct with kitchen range.Air inlet pipe 7 closely stretches into to be responsible in 1, it is bent to is responsible for 1 15 places, bottom.Air inlet pipe 7 all is connected on the source of the gas with sebific duct, pressure-reducing valve.Its person in charge's 1 bottom is connected to a liquid-feeding tube 17 in addition.

Be provided with a unidirectional conducting valve 41 in air inlet pipe 7, the metered flow of valve base alive 10 bores of this unidirectional conducting valve is consistent with pressure-reducing valve 24 metered flows.On valve base 10 tops of living one surge chamber that resembles a pear in shape 9 is arranged in addition, it plays cushioning effect to the gas of the air inlet pipe 7 of flowing through, avoid being responsible for 1 interior liquid in use and the gas barrier layer occurred, the outside liquid that rises with gas in use of surge chamber (being equivalent to a gas dome) is stopped and is attached at surge chamber 9 outer walls and is responsible on 1 inwall in addition, automatically fall within the lower liquid under after cooling, thereby reduced the loss of liquid.

In addition owing to be responsible for the effect of liquid in 1, can the filtering liquefied gas in some impurity.Thereby protect and prolonged the service life of kitchen range gas outlets.

Fig. 2 has shown an embodiment of check valve 41.This check valve 41 comprises valve base 10 alive, live valve 11 and the valve seat 12 of living.

Fig. 3 has shown the utility model method to set up in use.Wherein 28 is gas kitchen, and 22 is gas tank (also coal gas air supply pipe), the 23rd, and angle valve, 25,27 is tube connector, the 26th, rubber cap.

In use, after the utility model device is set by Fig. 3, suitable liquid (as water or a kind of special liquid oil) is added among the person in charge 1, reach the height that is lower than check valve 41 until liquid, and flood the outlet 15 of air inlet pipe 7 through liquid-feeding tube 17.Then, with rubber cap 26 mouth 18 of liquid-feeding tube 17 is sealed again.

When angle valve 23 is opened, and the gas kitchen switch does not have bubble at outlet 15 places of pipe 7 to emerge when cutting out, and it is normal then to explain the situation.But if this moment, opening 15 places had bubble to emerge, show that then the part in this device downstream has gas leakage, when angle valve 23 is fastened, and the gas kitchen switch has bubble to emerge as if opening 15 places when opening, and illustrates that then angle valve 23 fails to close tight or have damage.Like this, the bubble situation at opening 15 places by observing air inlet pipe 7 can be judged gas kitchen leather hose road and whether have the gas leakage problem, can prevent also that in addition angle valve from scurrying the service life that Cheng Bingneng prolongs angle valve.

When some gas-cooker, send the whip sound sometimes, at this moment might introduce gas pipeline to fire.The pipe internal cause is heated and pressure increases, thereby makes the liquid be responsible in 1 together with living valve 11 risings and abutting on the valve base 10 alive, thereby turn-offed gas, fire is extinguished automatically.Then can refire and continue to use.

When angle valve and Range switch are all opened, first, air inlet pipe 7 lower openings 15 places do not have to turn on the bubble, just prove that pressure gas has used up or pressure-reducing valve, angle valve blocked.The second, the gas barrier layer appears in the liquid of being responsible in 1 always, and the gas flow speed of coming out from the kitchen range mouth is very high, just need bar up angle valve maintenance pressure-reducing valve rapidly, and this phenomenon is exactly pressure-reducing valve malfunctioning (being the high pressure gas transmission).

After the stage of use, when liquid level drops to the above 5mm in 15 places, bottom of air inlet pipe 7, must add liquid more in addition.

The utility model burning gases AQF-5 type product is to use withstand voltage transparent material, makes as glass etc., withstand voltagely should reach 30 ℃, 14Kg/Cm ²

We not only produce the burning gases safety device, and multi-form a kind of in addition with principle.As shown in Figure 4, though it does not have a such surge chamber, essence also can be more better, and because of the tubule that stretches into the person in charge from air inlet pipe is a back cover, the pipe bottom side is equipped with the hole of constant flow, and the air-capacitor amount of this arm is not second to the air-capacitor amount of surge chamber.It still has the prolongation liquid function of service time in addition, but the gas outlet is stretched into and is had unidirectional conducting valve in the person in charge, tubule has replaced the effect of surge chamber outer wall, and play the double insurance effect again, more different from the liquid feeding oil, it has check valve and the tubule bottom stretched in being responsible for also can have scale.More can read what of liquid in being responsible for exactly.

Claims

1, burning gases safety device, it can be connected between liquefaction source of the gas and the gas-cooker by sebific duct, it is made with withstand voltage transparent material such as glass etc., be used for observing gas leakage and prevent tempering, it is characterized in that being responsible for 1 gentle the insertion hermetically and be responsible for 1 air inlet pipe 7, this air inlet pipe 7 stretches into to be responsible for 1 part and to be bent downwardly and to arrive and be responsible for 1 bottom, and being responsible for 1 top has the escape pipe 2 that joins with the burning gases kitchen range, and is responsible for 1 bottom and has liquid-feeding tube 17.
