Abstract
The utility model discloses a gas phase mouth entering-liquid prevention device, comprising a cup-shaped protection cover. The upper part of the cup-shaped protection cover is provided with a gap for inserting a gas phase pipe, and the bottom part and/ or the side wall of the cup-shaped protection cover is provided with a plurality of vent holes. The total area of the vent holes is larger than the sectional area of the gas phase pipe. The gas phase mouth entering-liquid prevention device can play a role for stopping liquid, can effectively reduce force of impact of the liquid in splashing to let the splashed liquid to fall back a tank, can ensure that gas can smoothly enter from the gas phase pipe, and can not let the gas to flow back the gas phase pipe as the gas is accumulated in the cup-shaped protection cover, therefore protecting the pipeline out the tank against influence and prolonging the using life of a tank truck.
Description
Technical field
The utility model relates to the gas phase pipe in the liquefied gas transport trolley, and particularly a kind of gas phase mouth is prevented into liquid device.
Background technology
Railway Tank Cars for Liquefied Gas inside is equipped with the gas phase pipe usually, the outer end of the jar of gas phase pipe is positioned at place, tank body below the gas phase shutoff valve is installed, and one brings out the gas-phase space that mouth is positioned at the tank body top in jar, supplied gas turnover tank car, cause between tank car and the storage tank and produce pressure reduction, make things convenient for the loading and unloading of pot liquid.Transport trolley in the process of moving, pot liquid rocks and splashes, cryogenic liquid is easy to flow to the gas phase pipe by the jar inner outlet of gas phase pipe, enter the lower outer pipeline of jar of level attitude, cryogenic liquid can absorb the heat of shell and vaporize at this moment, cause tank interior pressure to increase, and then can influence the in-use performance of tank car.
The utility model content
For addressing the above problem, the utility model provides a kind of interior liquid of tank car that can effectively prevent to be splashed into the device of gas phase pipe jar inner outlet in transportation.
The utility model is that the technical scheme that its problem of solution is adopted is:
A kind of gas phase mouth is prevented into liquid device, comprise the cup-shaped protecting jacket, the top of cup-shaped protecting jacket is provided with a breach that is used to peg graft the gas phase pipe, and the bottom of described cup-shaped protecting jacket and/or sidewall are provided with a plurality of air extractor vents, and the gross area of described air extractor vent is greater than the sectional area of gas phase pipe.
Further improvement as such scheme, described cup-shaped protecting jacket comprises oversheath and inner sheath, leave the space between inner sheath and the oversheath, the bottom of inner sheath and/or sidewall are provided with a plurality of inner sheath air extractor vents, the bottom of oversheath and/or sidewall are provided with a plurality of oversheath air extractor vents, and inner sheath air extractor vent and oversheath air extractor vent constitute described air extractor vent.
The beneficial effects of the utility model are: gas phase mouth of the present utility model prevents can being installed on into liquid device the tank body inner top of cryogenic liquid pot type transport trolley, inserts the breach of gas phase pipe from the cup-shaped protecting jacket.In the transport trolley driving process, when pot liquid splashes because of rocking, the cup-shaped protecting jacket can play barrier effect to liquid, impulsive force in the time of effectively reducing liquid splash, therefore the liquid that splashes can fall back in the jar, the gross area of the air extractor vent on the cup-shaped protecting jacket guarantees that greater than the sectional area of gas phase pipe gas can enter smoothly from the gas phase pipe, can not flow back to the gas phase pipe because of gas build causes gas in the cup-shaped protecting jacket; In addition, being provided with of inside and outside sheath formed the twice barrier, and pot liquid has small part liquid via through holes and enters in the oversheath, at this moment when splashing on the cup-shaped protecting jacket, inner sheath forms resistance once more to liquid, makes to be splashed into the aperture of liquid on two-layer sheath and to flow back in the jar.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is installed on cutaway view in the cryogenic liquid transport trolley tank body for the utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of gas phase mouth of the present utility model is prevented into liquid device, comprise cup-shaped protecting jacket 1, the top of cup-shaped protecting jacket 1 is provided with a breach 3 that is used to peg graft gas phase pipe 2, the bottom of described cup-shaped protecting jacket 1 and/or sidewall are provided with a plurality of air extractor vents 4, and the gross area of described air extractor vent 4 is greater than the sectional area of gas phase pipe 2.Liquid in jar in the liquid phase space 7 splashes in the gas-phase space 6 because of rocking, cup-shaped protecting jacket 1 can play barrier effect to liquid, impulsive force when effectively reducing liquid splash, therefore the liquid that splashes can fall back in the jar, a jar internal pressure is remained unchanged, the gross area of the air extractor vent 4 on the cup-shaped protecting jacket 1 guarantees that greater than the sectional area of gas phase pipe 2 gas can enter smoothly from gas phase pipe 2, can not flow back to gas phase pipe 2 because of gas build causes gas in cup-shaped protecting jacket 1.
Further, described cup-shaped protecting jacket 1 comprises oversheath 11 and inner sheath 12, leave space 10 between inner sheath 12 and the oversheath 11, the bottom of inner sheath 12 and/or sidewall are provided with a plurality of inner sheath air extractor vents 41, the bottom of oversheath 11 and/or sidewall are provided with a plurality of oversheath air extractor vents 40, and inner sheath air extractor vent 41 and oversheath air extractor vent 40 constitute described air extractor vent 4.As preferred embodiment, have breach 3 on oversheath 11 and the inner sheath 12, gas phase pipe 2 inserts in the inner sheath 12 in breach 3, and oversheath 11 passes through welded seal with tank body 5 tops and gas phase pipe 2 appearances respectively, to guarantee that pot liquid can not enter gas phase pipe 2; Inner sheath 11 has formed the twice barrier with being provided with of oversheath 12, pot liquid has small part liquid in oversheath air extractor vent 40 enters space 10 between oversheath 11 and the inner sheath 12 when splashing on the cup-shaped protecting jacket 1, at this moment, 12 pairs of liquid of inner sheath form resistance once more, make to be splashed into liquid and to flow back to liquid phase space 7 through oversheath air extractor vent 40; Inner sheath air extractor vent 41 and oversheath air extractor vent 40 have guaranteed that gas can turnover smoothly between the gas-phase space 6 in gas phase pipe 2 and jar.
As shown in Figure 2, described oversheath air extractor vent 40 is staggered state with inner sheath air extractor vent 41 positions.Inner sheath air extractor vent 41 and oversheath air extractor vent 40 are staggered, can effectively tackle liquid by the oversheath air extractor vent 40 jar interior liquid phase space 7 that makes it to fall go back to.
The gross area of described inner sheath air extractor vent 41 is greater than the sectional area of gas phase pipe 2.
The gross area of described oversheath air extractor vent 40 is greater than the sectional area of gas phase pipe 2.
For guaranteeing that gas can unimpeded turnover between gas phase pipe 2 and gas-phase space 6, can evenly bore some diameters on oversheath 11 and inner sheath 12 is the aperture of 8mm, and the gross area of aperture is greater than the sectional area of gas phase pipe 2.
Certainly, the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
