Abstract

The utility model relates to a gas-fired appliance gas tightness checkout gear, in particular to a gas-fired appliance gas tightness detecting instrument aiming at solving the problems that the conventional detecting instrument has multiple interfaces and may generate a plurality of gas leakage points thereby normal usage is affected. The utility model includes a U-type manometer on which an arm of a U-type tube is provided with a side tube. The end of the side tube is connected with a leather bag by an air duct hose. The two tube mouths of the U-type tube on the U-type manometer are respectively communicated with atmosphere. The utility model provides the side tube on one arm of the U-type tube and the end of the side tube is connected with the leather bag by air duct hose thereby saving a tee pipe used in conventional technology. The utility model not only has more concise structure, easier producing and low cost, but also has convenient usage, fewer interfaces, safety and reliability, which is applicable for industrial and civil gas-fired appliances as gas kitchen range, gas water heater and the like.

Description

Combustion gas tool air-leakage detector

Technical field

The utility model relates to combustion gas tool air-tightness detection device, is specially a kind of combustion gas tool air-leakage detector.

Background technology

In daily life, along with gas-cooker, gas water heater etc. are the utensil widespread use in the family of fuel with the inflammable gas, often have the accident that causes personal property to incur loss because combustion gas tool poor sealing performance causes gas leakage to take place, its security more and more is subject to people's attention.At present developed country all wants the gas leakage amount of strict by-pass valve control, switch and pipeline to industry and burners such as civil gas stove, gas water heater, and the impermeability index has been made strict regulations, and China is no exception.And now whether people adopt the coal gas leak locator to detect combustion gas tool such as gas-cooker to leak gas usually, but this leak detector configurations complexity is used inconvenience, and price is more expensive; And be subjected to the restriction of testing conditions when using, it must have certain danger keeping could finding whether to have gas to leak from Gas appliance under combustion gas tool and the condition that the conveying gas pipeline communicates.Some are simple in structure so people have developed on this basis, easy to use, the reliable detection instrument, it such as the patent No. Chinese patent of 200520023974, its technical scheme comprises U-tube manometer, a mouth of pipe of the U type pipe of U-tube manometer is connected with three-way pipe by soft air-guide pipe, another mouth of pipe of three-way pipe links to each other with the leather bag of calming the anger by soft air-guide pipe, this detector is compared with traditional leak locator, though it is simple in structure, easy to use, but constitute by mutual socket between each parts, nearly 6 interfaces, like this when detecting combustion gas tool impermeability, produce 6 leakage points probably owing to each interface junction imprecision, influence the normal use of detector, cause testing result inaccurate, and the processing technology complexity of three-way pipe wherein, cost is higher.

Summary of the invention

The utility model exists interface more and produce a plurality of gas leakage points probably and influence the problem of its normal use in order to solve existing detector, and a kind of combustion gas tool air-leakage detector is provided.

The utility model is to adopt following technical scheme to realize: combustion gas tool air-leakage detector, comprise U-tube manometer, an arm of the U type pipe on the U-tube manometer is provided with other pipe, other pipe is terminal to link to each other with the medical leather bag of calming the anger by soft air-guide pipe, and two mouths of pipe of the U type pipe on the U-tube manometer communicate with atmosphere respectively.

The existing product that U-tube manometer described in the utility model and the medical leather bag of calming the anger are public offerings on the market, the medical leather bag of calming the anger can be the leather bag of calming the anger used on the medical sphygmomanometer, and fundamental purpose is to realize manometric unidirectional calming the anger.

Detector described in the utility model has only 3 interfaces, leakage point is less, when test combustion gas tool impermeability, at first make combustion gas be in closed condition, U type pipe is provided with the mouth of pipe on the arm of other pipe by soft air-guide pipe and gas-cooker, gas water heaters etc. are that the air intake opening sealing of the combustion gas tool of fuel is communicated with the inflammable gas, the mouth of pipe on another arm communicates with atmosphere, utilize the medical leather bag of calming the anger to carry out pneumatic compression then, this moment, the interior indicating liquid of U type pipe of U-tube manometer began to move along U type pipe under the gaseous tension effect, it is poor that certain altitude appears in the liquid level in U type pipe two arms, if the lower seal performance is good in off position for the combustion gas tool, then the difference in height of U type pipe two liquid levels can not change within a certain period of time; If the very fast disappearance of difference in height of U type pipe two liquid levels returns to previous status, the gas leakage down in off position of detected Gas appliance then is described, its sealing property is relatively poor.

Compared with prior art, the utility model is provided with the side pipe on an arm of U type pipe, and other pipe is terminal to be connected with leather bag by soft air-guide pipe, has saved three-way pipe of the prior art, and not only structure is more succinct, manufacturing is easier, cheap; And easy to use, interface is less, and is safe and reliable, is suitable for burners such as industry and civil gas stove, gas water heater and uses.

Description of drawings

Fig. 1 is a structural representation of the present utility model

Among the figure: the other pipe 4 of 1-U U-tube manometer 2-U type pipe 3-, the medical leather bag of calming the anger of 6-soft air-guide pipe 5-

Embodiment

Combustion gas tool air-leakage detector, comprise U-tube manometer 1, an arm of the U type pipe 2 on the U-tube manometer 1 is provided with other pipe 3, and other pipe 3 ends link to each other with the medical leather bag 5 of calming the anger by soft air-guide pipe 4, and two mouths of pipe of the U type pipe 2 on the U-tube manometer 1 communicate with atmosphere respectively.During use, the air intake opening that U type pipe 2 is provided with the mouth of pipe on the arm of other pipe 3 and by soft air-guide pipe 6 and gas-cooker, gas water heater etc. with the inflammable gas is the combustion gas tool of fuel seals and is communicated with, the mouth of pipe on another arm communicates with atmosphere, push the medical leather bag of calming the anger then so that U type pipe is carried out unidirectional calming the anger, by the principle of linker as can be known, fluid column pressure in U type pipe two arms is not simultaneously, to produce liquid level difference, if the lower seal performance is good in off position for combustion gas this moment tool, then the difference in height of U type pipe two liquid levels can not change within a certain period of time; If the very fast disappearance of difference in height of U type pipe two liquid levels returns to previous status, the gas leakage down in off position of detected Gas appliance then is described, its sealing property is relatively poor.

Claims

1, a kind of combustion gas tool air-leakage detector, comprise U-tube manometer (1), it is characterized in that: an arm of the U type pipe (2) on the U-tube manometer (1) is provided with other pipe (3), other pipe (3) is terminal to link to each other with the medical leather bag of calming the anger (5) by soft air-guide pipe (4), and two mouths of pipe of the U type pipe (2) on the U-tube manometer (1) communicate with atmosphere respectively.
