Description
The present invention relates to a kind of liquefied petroleum gas (LPG) storage device, especially a kind of liquefied petroleum ga steel cylinder.
Chinese patent ZL00208164.4 discloses a kind of liquefied petroleum ga steel cylinder, and it comprises bottle, angle valve, reduction valve, and has dividing plate that steel cylinder intracavity is divided into two air chambers up and down, and last chamber volume is less, is vaporizing chamber, and following chamber volume is the liquid storage power house greatly.Indoor down have a conduit that leads to the steel cylinder bottom to be communicated with two Room up and down.The lower end of conduit contacts and leaves liquid entering hole feed flow gasification with liquid storage power house bottom and flows into; The upper end-hole sealing has spray-hole on the catheter wall at end socket place.In use, the liquid in the steel cylinder liquid storage power house is ejected into vaporizing chamber through conduit under the effect of pressure of the inside of a bottle, because pressure reduces and forms vaporific or evaporate into gas, flows out angle valve then, reduction valve burns.But when raffinate more for a long time, raffinate can be full of vaporizing chamber, can not vaporize, even flow out steel cylinder and enter reduction valve, causes liquid, can not use.In addition because the liquefied petroleum gas (LPG) composition is more assorted, second-rate, when containing more unsuitable volatile ingredient, especially temperature is lower than Celsius 8 when spending, and the evaporating capacity of liquid gas is very little, and the steel cylinder internal pressure is very low, use soon, steel cylinder has not just had pressure, and liquid gas can not be forced out use.
The object of the present invention is to provide a kind of reduction valve that can prevent to cross liquid, can make raffinate fully vaporize and at first burnt again, and make the liquefied petroleum ga steel cylinder that enough pressure is arranged in the steel cylinder all the time.
The present invention is achieved in that
It comprises bottle, angle valve, with the vaporizing chamber of angle valve internal orifice close communication, the liquid entering hole that has in the lower end that reaches liquid storage power house bottom the conduit of spray-hole is arranged in the vaporizing chamber of upper end, is provided with unidirectional relief valve on the catheter wall that is positioned at liquid storage power house inside.
Vaporizing chamber is the air bag that elastic material is made, and the catheter interior plug that air bag surrounded is disconnected, on the disconnected place of plug catheter wall up and down spray-hole is arranged respectively, and the conduit upper end is closely connected with the angle valve internal orifice.
In the liquid storage power house, be filled with the inert gas of certain pressure.
The Lower Half of the conduit of the position of unidirectional relief valve in steel cylinder liquid storage power house.
Unidirectional relief valve is made up of hole on the catheter wall and curtain lid.
The present invention has following beneficial effect:
When opening angle valve, gas in the vaporizing chamber flows out, pressure reduces, the raffinate that is stored in liquid storage power house bottom enters conduit and flows to gasification room rapidly from the liquid entering hole of conduit bottom under pressure, this moment, one-way valve was because manifold pressure is low, the raffinate flow velocity is very big and close, raffinate through spray-hole be ejected into vaporizing chamber and atomize or evaporate into gas after flow out the steel cylinder burning.Liquid in conduit rises to certain height, and during pressure balance in vaporizing chamber internal pressure and the liquid storage room power house, flow rate of liquid descends in the conduit, and the pressure at one-way valve place is in state of equilibrium, one-way valve opens, and raffinate flows back in the bottle from unidirectional relief valve.The interior gas of vaporizing chamber this moment continues to flow out burning, and pressure descends once more, and at this moment raffinate from the rising of liquid storage power house bottom, sprays into vaporizing chamber, closed check valve again.When the vaporizing chamber internal pressure was enough high, raffinate flowed back to the liquid storage power house from one-way valve again.So repeatedly, can there be liquid in the vaporizing chamber, just can not cause reduction valve to cross liquid yet.The opening and closing repeatedly of one-way valve make liquid circulate repeatedly, stir between storage mobilization force chamber and conduit, and raffinate can at first be vaporized and be mixed with the light gas of part and flow out burning.Through experiment, reserves are that 15 kilograms steel cylinder adopts this structure, and one jar does not have the raffinate residue after running out of air.The Lower Half that unidirectional relief valve is located at conduit has increased stirring, the mixing to the bottom raffinate, and it is fully vaporized.
Gasification room is made the air bag of being made by elastic material, can directly the old steel cylinder of single chamber be reequiped, and not change the raw steel bottle structure, and its cost is very low, does not also change original production process.The elasticity of air bag can make it be in swelling state all the time, and guaranteeing has enough gasification spaces, is convenient to again install.One-way valve is made the valve block shape, makes simply, increases cost hardly.
Charging into of inert gas can guarantee to remain enough pressure in the steel cylinder liquid storage power house, liquid gas all can be extruded.Inert gas is stored in the top of liquid storage power house all the time, can be by first discharge, even jar is gone into a large amount of liquid gas that should not vaporize in the steel cylinder, the pressure of inert gas also can extrude steel cylinder with liquid gas and normal the use.
Fig. 1 is the structural representation of one embodiment of the present of invention.
Fig. 2 is the structural representation of an alternative embodiment of the invention.
Below in conjunction with accompanying drawing the present invention is done and to describe in further detail:
As shown in Figure 1, this steel cylinder comprises angle valve 1, reduction valve 2, bottle 6, and at bottle 6 inner tight welding one dividing plates 10, dividing plate 10 is divided into the vaporizing chamber 3 on top and the liquid storage power house 8 of bottom with steel cylinder, and the volume ratio of vaporizing chamber 3 and liquid storage power house 8 is 1: 20.Tighten a conduit 5 that leads to steel cylinder liquid storage power house 8 bottoms at dividing plate 10, there is liquid entering hole conduit 5 lower ends, the sealing of conduit 5 upper end-hole, on the wall of conduit 5 upper ends, have one group of spray-hole 4 that leads to vaporizing chamber 3, spray-hole 4 is perpendicular to tube wall, and the gross area of spray-hole 4 equals the area at the minimum endoporus place of angle valve 1.A catheter length place of/4th settles a unidirectional relief valve 7 at the bottom of the bottle in conduit 5 bottoms.Unidirectional relief valve 7 is made up of a hole on conduit 5 walls and a film, and film ties in and on the outer wall of conduit 5 port lid lived.The atmospheric nitrogen of packing in the steel cylinder, nitrogen was packed into before the can liquid gas.The nitrogen that are stored in the vaporizing chamber 3 just flow out when opening angle valve for the first time, and the nitrogen that are stored in the liquid storage power house 8 gather on liquid gas, do not need to charge into nitrogen once more during the can liquid gas again.When opening angle valve 1 and use gas, raffinate rises rapidly in the conduit 5 and sprays into vaporizing chamber 3, after vaporizing chamber 3 internal pressures raise, raffinate flow velocity in the conduit 5 descends, and one-way valve 7 is opened, and raffinate flows back in the liquid storage power house, circulation is stirred so repeatedly, makes raffinate at first flow out burning.
