Abstract
The invention provides a dual-calibre gas bottle valve, which is provided with a large calibre, a small calibre, a left thread, a right thread, a lock and a retaining device. An air inlet is a special charging mouth used for charging a unit control pipe; a charging unit is provided with the lock; an air outlet is a user port where the retaining device is arranged. The charging can be carried out only when the owner opens the lock. When the charging is carried out at the air outlet with violation, the retaining device refuses charging; meanwhile, the air inlet is changed to have the small calibre and the right thread, thus avoiding reverse pouring from a large bottle to a small bottle. The gas bottle valve design can avoid the mistaken charging, cross charging, flow charging, area-span charging, reverse bottle charging of the gas bottle, can determine the responsible mainbody, consolidates the property right transfer of the gas bottle and fixes the charging fruit.
Description
Affiliated technical field:
The present invention relates to petrochemical industry, all kinds of gas gas cylinder of gas industry cylinder valve constructional device, can become the unique obligee of filling in all kinds of gas fillings station, really the gas cylinder control, administrative power is given back fueling station, can stop the gas cylinder misloading, flowing fills, trans-regionally to fill, fall bottle and fill; Can determine the responsible party at cylinder filling station, consolidate the gas cylinder property right, fixedly fill achievement, solve the puzzlement of the gas filling head of a station since the phase.
Background technique:
At present, the gas cylinder cylinder valve of known use all is that single port fills, puts structure, with about, internal and external threads difference.Its principal mode is the conical surface shape of the mouth as one speaks circle sealing of sphere and the inclined-plane sealing or the double step of double step.In fact non-exchange Conncetion cimension has 42 groups, and these group sizes are distributed to 15 classes, 100 multiple gases.The cylinder valve that China produces at present has kind more than 20, mainly contains liquefied petroleum gas cylinder valve (GB7512-1998), hydrogen cylinder valve (GB10877), dissolved acetylence cylinder valve (GB10879), argon gas cylinder valve (GB17877-1999), compressed natural gas cylinder valve (GB17926-1999), automobile steel bottle filled with compressed natural gas valve, analytic expression automotive LPG steel cylinder valve, propylene cylinder valve, propane cylinder valve etc.By its structure, the gas cylinder cylinder valve has kinds such as pin chip, telescopic, hook shaft type, pin pattern, diaphragm type and ball pressure type.
There are many defectives in the cylinder valve that this single port fills, puts structure: a whole nation name class cylinder filling (storage is joined) stand and is all existed the area under one's jurisdiction to exceed the time limit not examine the phenomenons that behavior is secretly random with gas cylinder safely management exposed conduit, responsible party's name is deposited powerful position such as steel cylinder trans-regionally fills, gas cylinder fistulae, the operation of band hidden danger.
Summary of the invention:
Shift, fixedly fill achievement for consolidating the gas cylinder property right conscientiously, the present invention can allow each fueling station have own control, administrative power, special-purposely belongs to that one of formation independently fills colony in the district own specific filling, and this intragroup gas cylinder exchange is mobile.This just makes between fueling station and the fueling station, between fueling station and the user, form firmly constant restricting relation between fueling station and the bottled gas distributors, ajust the position that fueling station bears all the responsibilities to gas cylinder safely, thoroughly stopped gas cylinder misloading, mistake dress, the unlawful practices such as bottle fills, the strange land fills of falling.
The technical solution adopted for the present invention to solve the technical problems is:
Cylinder valve is the important control hardware of gas cylinder.It is a kind of device of control gaseous, and the control of having grasped cylinder valve just equals to have caught " ox muzzle " of gas cylinder.
The present invention makes cylinder valve into twoport, one-in-and-one-out, and import fills mouth as the special use of the unit's of filling keyholed back plate, and the suction port bore can or change right-hand thread into less than the air outlet bore, prevents that big bottle from pouring in down a chimney to bottle.And set up on their own by the unit of filling and to fill password or office.The air outlet installs the non-return structure additional for to use the registered permanent residence.The non-return structure can be located at steam outlet pipe, also can be located at the valve body middle part, can bore an aperture suit check device on the valve rod valve.
The invention has the beneficial effects as follows: when fueling station beyond the obligee and selling outlets fill gas from the air outlet in violation of rules and regulations in bottle, this moment, the external gas pressure was greater than empty bottle pressure, utilize the gas impulse force, check device and sealing rubber circle press valve seat, prevent to fill in bottle from outlet.
Because suction port changes into small-bore or right-hand thread, can prevent to pour in down a chimney to bottle with big bottle from suction port.

Embodiment:
When desiring to fill gas in gas cylinder, will lock and open clockwise at an angle of 90, the ball valve passage is communicated with conduit.Pressure in the gas cylinder is greater than external pressure at this moment, and gas charges in the gas cylinder by pipeline.
If stop to fill, lock is rotated counterclockwise 90 ° of angles, ball valve is closed, and blocks gas communication.
When user such as need were used gas, to counterclockwise rotating, this moment, valve rod was along with handwheel rotates with the handwheel of cylinder valve, and by the rising of sleeve drive valve, pressure of the inside of a bottle utilizes the gas impulse force to back down check device and communicates with the air outlet greater than external pressure at this moment, and gas just can flow out gas cylinder.
Dock with reduction valve still by current standard the air outlet.
