The hollow is connected with the gas outlet of the valve and is provided with air-breather. The utility model is characterized in that the hollow pole is provided with a movable valve and the bottom of the air-breather is provided with stopping valve to prevent the liquefied petroleum gas from overflowing. The device to utilize raffinate of liquefied petroleum gas of the utility model is simple, secure and reliable.
Description
Technical field
The utility model relates to a kind of residual liquid device of liquid gas.
Background technique
In the process that liquid gas uses, raffinate is all arranged in steel cylinder usually, if be not used, then can cause a large amount of energy wastes.The liquefied gas residue utilized device of prior art generally is that hollow tubular is set in steel cylinder, and an end of hollow tubular is communicated with cylinder valve, and the other end then extends the steel cylinder bottom.By forms such as air vent or inlet opening are set on hollow tubular, utilize the liquid gas of the pressure official post bottom of gas in the bottle to discharge along hollow tubular, reach the purpose that makes full use of liquefied gas residue., because the diameter of hollow tubular is less, gas will be in hollow tubular enters bottle, so inflationtime is longer when pneumatic inflation.And in the bigger occasion of some gas flow demands, when gas is discharged, occur easily crossing the phenomenon that liquid is discharged with gas at the bottom of ambassador's bottle because of draught head, except having reduced burning quality, also can cause certain potential safety hazard, therefore Security of existing liquefied gas residue utilized device and reliability are relatively poor, and applicable scope is narrower.
Summary of the invention
Goal of the invention of the present utility model is to overcome the deficiencies in the prior art, and the residual liquid device of liquid gas a kind of simple in structure, safe and reliable is provided.
Goal of the invention of the present utility model is achieved in that a kind of residual liquid device of liquid gas, comprise valve body and be located on the valve body and extend the hollow stem of steel cylinder bottom, hollow stem is communicated with the air outlet of valve body, and have vent on the hollow stem, it is characterized in that: described hollow stem is provided with a pair of moving valve, and the below of vent is provided with the resistance valve that can prevent that liquid lng from overflowing.
Described moving valve comprises a hollow casing and the housing cavity is divided into the seal ring of epicoele, cavity of resorption, the top of housing and bottom are respectively equipped with cover plate and seal ring, be respectively equipped with the spool that matches with seal ring in epicoele and the cavity of resorption, epicoele is communicated with steel cylinder with exhaust port, and cavity of resorption is communicated with hollow stem with intercommunicating pore.
Described resistance valve comprises valve casing and the choked flow spool that external diameter is littler than valve casing internal diameter that is connected with the hollow stem one.
Described choked flow spool top is provided with the conical seat of salable valve casing air outlet.
The outer surface of described choked flow spool be provided with at least two can and the valve casing internal surface between the boss that mutually slides.
Described choked flow spool bottom surface is provided with at least two supporting bases.
The bottom of described hollow stem is provided with the damping spring that can withstand on the steel cylinder bottom surface.
The utility model improves existing liquefied gas residue utilized device, the a pair of unidirectional moving valve that is communicated with hollow tube and steel cylinder respectively is set on hollow tube, when the traffic demand of liquid gas was big, liquid gas can be discharged from vent and intercommunicating pore respectively, strengthen the flow of liquid gas.Excessive when the steel cylinder internal pressure differences, when gushing on the liquid of steel cylinder bottom, the resistance valve pressurized that is located at the vent below is closed, and liquid can not be discharged outside the steel cylinder, has effectively guaranteed burning quality and Security.
Description of drawings
Fig. 1 is the structural representation of the utility model most preferred embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
According to shown in Figure 1, liquefied gas residue utilized device of the present utility model comprises valve body 1 and hollow stem 2, and an end of hollow stem 2 is communicated with the air outlet of valve body 1, and the other end then extends the steel cylinder bottom, and is provided with a damping spring 4 that can withstand on the steel cylinder bottom surface.Have vent 3 on hollow stem 2, liquid gas can be discharged valve body 1 through vent 3.Be provided with a pair of moving valve on the side surface of hollow stem 2, moving valve mainly comprises a hollow casing 5 and seal ring 6, and seal ring 6 is divided into epicoele and cavity of resorption to the cavity of housing 5, and the top of housing 5 and bottom are respectively equipped with cover plate 7 and seal ring 8.Be respectively equipped with the spool 9,10 that matches with seal ring 6,8 in epicoele and the cavity of resorption.Epicoele is communicated with steel cylinder by an exhaust port 11, and cavity of resorption then is communicated with hollow stem 2 with an intercommunicating pore 12.Be provided with a resistance valve on hollow stem 2, resistance valve is positioned at the below of vent 3.Resistance valve is made up of valve casing 13 and choked flow spool 14.Wherein valve casing 13 is connected for one with hollow stem 2; The external diameter of choked flow spool 14 is then little than valve casing 13 internal diameters.The top of choked flow spool 14 is provided with a conical seat, and conical seat when can push up on choked flow spool 14 seals the air outlet of valve casing 13.The outer surface of choked flow spool 14 is provided with at least two boss 15, boss 15 can and valve casing 13 internal surfaces between slide mutually, and the bottom surface of choked flow spool 14 is provided with at least two supporting bases 16, supporting base 16 can be unsettled choked flow spool 14 bottom surfaces.When steel cylinder was in inflated condition, liquid gas was along hollow stem 2 inputs, and liquid gas enters in the steel cylinder through vent 3.Also can be by choked flow spool 14 is pressed down, the gap between boss on the choked flow spool 14 15 and valve casing 13 inwalls and the gap of supporting base 16 enter steel cylinder, liquid gas can also enter the moving valve cavity of resorption by intercommunicating pore 12, the spool 9 of pushing epicoele open enters steel cylinder, thereby has improved the speed that gas enters steel cylinder.In the liquid gas using process, when the traffic demand of liquid gas was big, liquid gas then can enter hollow stem 2 through the intercommunicating pore 12 of vent 3 and moving valve cavity of resorption, has guaranteed the output quantity of liquid gas.Cause when gushing on the bottom liquid when steel cylinder internal cause pressure difference is excessive, liquid promotes choked flow spool 14, the conical seat of choked flow spool 14 can not gush out to valve body 1 place liquid, has guaranteed the quality of burning and has improved the Security and the reliability of burning.
