Technical Field
The utility model relates to a detection device, especially detect natural gas leakage alarm device's test instrument specifically are a gas source generator who is used for testing alarm device probe sensitivity.
Background
Due to environmental requirements, many industrial boilers are changed from coal and oil fired to gas fired boilers. Natural gas is a clean and environment-friendly energy source, and a plurality of industrial boilers in cities are changed into natural gas for burning. The natural gas has a specific gravity of about 0.65, is lighter than air, and has the characteristics of no color, no odor and no toxicity. The natural gas belongs to flammable and explosive gas, the explosion limit (V%) is 5-15, and the safety key point is to prevent the natural gas from leaking in the using process. At present, natural gas burning leakage alarm devices are of various types, but an effective means for detecting the reliability of the natural gas alarm device is still lacked.
The natural gas alarm devices are arranged at the top of the house, are large in height from the ground, and are inconvenient to check in daily life; after long-term use, the natural gas alarm device cannot be effectively detected at present due to the fact that the performance and the sensitivity of the natural gas alarm device are reliable.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming not enough among the above-mentioned background art, provide a natural gas leakage alarm device tester to detect natural gas alarm device's sensitivity and reliability.
The technical scheme of the utility model is that:
the utility model provides a natural gas leakage alarm device tester which characterized in that: the tester comprises an elongated outer sleeve, a gas cylinder box arranged at the front end of the outer sleeve and used for accommodating a small gas cylinder, an inner sleeve which is slidably inserted in the outer sleeve and the front end of which abuts against the small gas cylinder, and a component pressure head which is positioned at the front end of the gas cylinder box and aligned with the opening of the small gas cylinder; when the inner sleeve pushes the small gas bottle forwards, the opening of the small gas bottle is pressed and opened by the pressure head of the component, and therefore gas for detecting the natural gas alarm device is released.
A hand wheel used for pushing the inner sleeve is arranged at the rear end of the outer sleeve; the wheel shaft of the hand wheel is screwed in and matched with the rear end of the outer sleeve through a thread structure, and the top end of the wheel shaft abuts against the rear end of the inner sleeve.
The gas cylinder box is formed by symmetrically arranging compression frame strips provided with openings, and the openings are matched with the small gas cylinders in size so as to accommodate the small gas cylinders to enter the gas cylinder box from the side faces of the gas cylinder box or take out the small gas cylinders from the gas cylinder box.
The outer sleeve is formed by splicing a plurality of thick sleeves, and every two thick sleeves are detachably connected through a thread structure.
The inner sleeve is formed by splicing a plurality of thin sleeves; the length of each section of the thin sleeve is the same as that of the thick sleeve.
The utility model discloses a theory of operation is: when a user rotates a hand wheel to push an inner sleeve and further push a small gas bottle forwards, the opening of the small gas bottle is pushed and opened by an assembly pressure head, a certain amount of natural gas is discharged around a natural gas alarm, the natural gas concentration can reach the alarm concentration required by the alarm device, and therefore after the actual natural gas leakage is simulated, whether the natural gas alarm device can give an alarm or not and the sensitivity of the alarm device are detected.
The utility model has the advantages that:
the utility model provides a detection device combines together the little gas cylinder of natural gas and member with adjustable length, can realize the function to the high altitude alarm device detection operation. The outer sleeve and the inner sleeve can be freely combined in length, and when the device is not used, the device can be disassembled for storage, so that the space is saved; the device has great help for eliminating potential safety hazards and safely using gas.

Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.
As shown in fig. 1, the gas cylinder box 1 arranged at the front end (right end in fig. 1) of the outer sleeve 9 is used for placing a small natural gas cylinder (small gas cylinder for short) 5, the side surfaces of the gas cylinder box are symmetrically arranged two compression frame members (preferably 3 cm wide), and the small gas cylinder 5 can be conveniently installed and replaced through an opening between the two compression frame members. The front end of the gas cylinder box 1 is provided with a component pressure head 4 for pressing open the small gas cylinder, when the inner sleeve 6 pushes the small gas cylinder forwards, the open end 2 of the small gas cylinder is compressed by the component pressure head 4, and natural gas can be sprayed out from the gas nozzle 3 of the gas cylinder, so that a natural gas atmosphere with a certain concentration is formed around the natural gas alarm device, and the natural gas alarm device is used for checking whether to start an alarm function. The concentration of natural gas contained in the natural gas vial should be at the upper explosive limit.
The front end of the outer sleeve is connected with the gas cylinder box through a thread structure, and the inner sleeve 6 used for pushing the small gas cylinder is slidably inserted in the outer sleeve.
The outer sleeve is formed by splicing a plurality of thick sleeves, and every two thick sleeves are detachably connected through a thread structure. The inner sleeve is formed by splicing a plurality of thin sleeves, every two thin sleeves are in plane contact without threaded connection, and the inner sleeve is mainly used for transmitting the thrust of the rotating hand wheel 13. Each section of the thin sleeve has the same length as the thick sleeve, so that each section of the thick sleeve and the thin sleeve are combined into a unit rod. Each section of unit rod piece is designed to be 1 meter long, and the number of the unit rod pieces can be increased continuously according to the required extension height.
