Along with the development of petrochemical industry, combustion gas more and more receives people's attention as a kind of chemical industry base stock and New-type fuel.Make fuel with combustion gas, easy for operation owing to its calorific value height, no flue dust, no breeze, get into people's sphere of life widely.In addition, combustion gas also is used for cutting metal, is used for the baking of agricultural products and the roasting of Industrial Stoves etc.

Resident living uses combustion gas and mainly contains line transportation and bottled supply dual mode.The line transportation mode mainly concentrates on big and medium-sized cities carries out, it be by gas company combustion gas and air, combustion gas and coal gas or combustion gas with after chemical fertilizer factory air discharged etc. is mixed, be delivered directly in the resident family through management and use.Bottled supply is through a sealing steel cylinder combustion gas to be assigned to every family by storage and distribution station; As the air supply source of family's kitchen range, it originates from early 1960s, is the earliest to use at oil refinery and several industrial city; Develop into the rural area, small towns at present, got into huge numbers of families.

Gas tank all has certain restriction service time; Should deliver to the competent departments concerned at the slack tank that surpasses this time and detect, that can continue to use just can fill gas again, and out of use just need doing scrapped processing; But traditional all is can use instead mutually between jar and the jar to the aerating of gas station; New gas tank possibly change into when changing and exceed time restriction, and illegal then businessman can continue to fill in the gas stream access customer hand, have potential safety hazard.

For strengthening the liquefied petroleum ga steel cylinder safety control; Eliminate safe hidden trouble; Accident prevention takes place; According to DOS's " special equipment safety monitor regulations ", State General Administration for Quality Supervision " gas cylinder safely supervision regulation ", etc. regulation and the administrative provisions of governments at all levels of rules, each department are carried out the LPG special-purpose bottle successively from 2003 and fixedly are filled management: i.e. the liquefied petroleum ga steel cylinder unit of filling, should be according to the principle of " who fills, whose management, who is responsible "; The special-purpose bottle of our unit can only be filled, special-purpose bottle or non-special-purpose bottle outside the our unit must not be filled.Carry out special-purpose bottle and help user, enterprise and social three aspects; But because the cylinder valve seat on the special-purpose bottle is not done any change; Make the cylinder valve of any National standard be installed on the special-purpose bottle, and then can all fill, order about down in interests in any unit of filling of family; The special-purpose bottle system is not observed by user and enterprise, and the special-purpose bottle system is performed practically no function.

 

Summary of the invention

The objective of the invention is to prevent that it from filling, can prevent down bottle, promptly effectively stop cylinder valve seat is filled in one bottle of antitheft that directs in another bottle.

The objective of the invention is to realize as follows: cylinder valve seat is filled in a kind of antitheft; Has body; Be provided with successively in the described body in lock, magnet, magnet spring and spring seat, the said lock and be provided with lock core; Said lock core one side is provided with steel ball, and said spring seat upper end is connected with body, and its lower end is connected with valve core spring.

Saying further, said lock core are provided with some apertures that are provided with dress magnet.

Saying further, two of said magnet magnetic poles.

Advantage of the present invention: can effectively check arbitrarily toward jar in filling gas, can effectively prevent in bottle, outwards to fall gas, can concentrate the gas tank control that exercises supervision service time, effectively reduce because of a jar security incident that causes.

1, it is all indefinite to be provided with the little hole number of dress magnet in magnet and the lock core, and place arbitrarily the position, and magnet is many more with the little hole number of dress magnet, and it is good more that ability is filled in antitheft.

2, the magnetic pole of magnet has two, and position and quantity that the aperture of magnet is installed on the lock core are arbitrarily, can work out out Several combination through position, quantity, polarity that magnet is installed.Do not have specific corresponding pole combination and enough big magnetic force then can not open antitheft and fill cylinder valve seat, supporting key is arranged so cylinder valve seat is filled in antitheft.If will inflate, can only pass through by gap very little between lock and the lock core, flow is restricted, and will accomplish inflation or the person of falling gas like this and need spend long time.This moment, the flux capacity of valve guaranteed normal combustion gas use.

 

Description of drawings

For content of the present invention is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, the present invention is done further detailed explanation, wherein:

Accompanying drawing is a structural representation of the present invention;

Embodiment:

See accompanying drawing, cylinder valve seat is filled in a kind of antitheft, has body 1; Be provided with successively in the described body in lock 2, magnet 4, magnet spring 5 and spring seat 8, the said lock 2 and be provided with lock core 3; Said lock core 3 one sides are provided with steel ball 6, and said spring seat upper end is connected with body 1, and its lower end is connected with valve core spring 7; Said lock core 3 is provided with some apertures that are provided with dress magnet 4, two of said magnet 4 magnetic poles.Its working principle is: the top that cylinder valve seat is placed in tank body is filled in antitheft, when not filling gas, does not move in the effect maintenance of magnet spring 5, and the gap between lock 2 and the lock core 3 is enough little, and is passage unique inside and outside the steel cylinder.The flow of the turnover of gas is all very little at this moment, has limited the fast aeration or the gas that outwards falls fast in bottle, but can guarantee the flow of proper functioning demand.If will inflate, must use the key with this matched with devices, the magnet 4 in the key repels with lock core 2 interior magnet mutually; Magnet 4 on the lock core 2 overcomes the elastic force of magnet spring 5; The part of magnet 4 in lock 2 apertures moved to lock core fully, and at this time under the effect of suction pressure, lock core 3 overcomes valve core spring 7 and lower spring cup 8 directions move; This moment, the gap of lock core 3 and lock 2 was increased to enough greatly, aerating speed and suitable when not installing this device additional.
