Abstract
The invention relates to a safety apparatus of a liquefied gas tank. The safety apparatus is characterized in that: the safety apparatus comprises a safety apparatus housing (7); both ends of the safety apparatus housing are respectively provided with an inner nut (1) and an outer screw (5); the inner nut is provided with an inner pad (6); a valve (9) and a truncated-cone-shaped valve plug (2) are arranged inside the safety apparatus housing; the truncated-cone-shaped valve plug is connected with a spring fixture (8), wherein the spring fixture is positioned on the right of the truncated-cone-shaped valve plug; a fixation bolt (3) is arranged between the spring fixture and the safety apparatus housing; the right end of the spring fixture is provided with a compression spring (4). The safety apparatus of the present invention has the following advantages that: the apparatus is convenient and practical, and has high sensitivity; with the apparatus, the generation of the fire disaster is reduced.
Description
Technical field
The present invention relates to the safty device that liquefied gas tank air outlet in use increases.It can be contained between liquefied gas tank air outlet and the reduction valve.
Technical background
Because reform and opening-up development in 40 years, the material progress in China town and country is greatly improved, and one of sign is exactly that the use amount of liquid gas sharply rises, and the use of liquid gas brings very big facility to people's life, but has also produced potential safety hazard simultaneously.Particularly some empty nestors of rural area and children set up safty device one for the liquid gas jar, the particular importance that just shows.The rare sale of liquefied gas tank safty device in the market, (29-BG33718) liquefied gas tank fire safety valve is exactly a kind of good relief valve, but still deposits shortcomings such as susceptibility is low in use, can play safety effect when having only the naked light of appearance.
Summary of the invention
The object of the invention just provides a kind of safty device of liquefied gas tank, and it can break off the liquefied gas tank air outlet, thereby play safety effect when liquefied gas tank air outlet temperature reach 100-130 degree centigrade automatically with extraneous.
To achieve these goals, the present invention adopts following technological scheme:
A kind of safty device of liquefied gas tank; It is characterized in that it comprises a safty device shell (7), is respectively inner nut (1) and outside nut (5) at the two ends of safty device shell, and an inner nut pad (6) is arranged on the inner nut; The safty device enclosure is provided with valve (9) and round table-like Valve plug (2); Round table-like Valve plug connects spring fixture (8) to the right, is provided with fixed bolt (3) between spring fixture and the safty device shell, and spring fixture right-hand member also is provided with pressure spring (4).
In the above-mentioned material; Inner nut is made with the steel nut of interior edge screw thread; Round table-like Valve plug is made with round table-like steel, and fixed bolt is processed by plastic polyethylene, and pressure spring is processed with the steel pressure spring; Outside nut is the screw manufacturing of hollow, and inner nut pad, safty device shell, spring fixture, valve all use the steel manufacturing.
Working principle of the present invention is: the safty device of liquefied gas tank are connected between the air outlet and reduction valve of liquefied gas tank: when normal the use; Liquid gas gets into the inside of this device through pressure spring; Go out by valve, by reduction valve the liquid gas decompression just can normally be used again.At clutch such as the high temperature that occurs catching fire, temperature surpasses 130 degrees centigrade, when being prone to the breaking out of fire situation; The fixed bolt that this device is inner no longer plays fixation because fusing point in 130 deg.c, will begin to melt; And pressure spring so can produce the power that pushes away left, inflexibly props up valve with round table-like Valve plug also because of when packing into, just being compressed part; The liquid gas that liquefied gas tank discharges is many more, and round table-like Valve plug just supports tightly more.Be the steel manufacturings because of what use again, be enough to make liquid gas not revealed, reduce fire and take place.
The invention has the advantages that: convenient and practical, highly sensitive, reduce fire and take place.
