Background technique
Currently, most automobile gas cylinders use Horizontal type vehicle-mounted liquefied natural gas bottle in the market, it is all made of air-liquid
Valve seat construction is mixed, the gentle phase pipeline of the liquid phase pipeline of gas cylinder is integrated in inside a valve seat, becomes gas cylinder internal and outside
The hinge of pipeline connection, so that gas cylinder all has the function of filling liquid, drain, empties, suppresses.But this air-liquid mixing valve
Holder structure has following technical problem:
1, from using functional perspective to analyze, the gas cylinder external feed flow stage, the gas cylinder filling liquid stage, the gas cylinder high pressure return-air stage,
Gas cylinder gas phase empty stage necessarily causes the non-working line closed on to contact low temperature since its pipeline is all integrated in inside valve seat
Medium increases the cryogenic media of gas cylinder internal and the contact of external high temperature environment.It will increase gas cylinder leaking heat in this way, reduce gas cylinder
Heat insulation capacity.
2, from angle analysis is manufactured, gas-liquid integrated valve seat will arrange filling liquid pipeline, outlet tube in the space of casing
Line, blow-down pipe, since integrated space is limited, pipeline in process of production can be there is a phenomenon where contacting with each other, and pipeline contact is led
It causes cryogenic media that short circuit phenomenon occurs, will increase gas cylinder leaking heat in this way, reduce gas cylinder heat insulation capacity.
3, it is analyzed from pipeline layout angle, gas-liquid integrated valve seat is not filled in gas cylinder clack box exterior tubing placement process
Divide the space using clack box, exterior tubing can only be arranged since integrated valve seat, is easy to make to be in contact between exterior tubing
Interference phenomenon, in the process of running, phase mutual friction between pipeline causes pipeline to be revealed to vehicle, so that natural gas is leaked and causes danger.
Utility model content
The purpose of this utility model is to provide a kind of automobile gas cylinders, and vapor delivery line and liquid phase pipeline are individually set
Meter reduces the leakage heat of gas cylinder, enhances the adiabatic heat-insulation ability of gas cylinder, gas cylinder is made to have longer hold time.
To achieve the above object, the utility model provides a kind of automobile gas cylinder, including bottle body, and bottle body includes that liquid phase connects
Mouthful gentle interfaces, it is independent on the side wall of bottle body to be provided with the gentle phase valve seat of liquid phase valve seat, the gentle interfaces of liquid phase interface point
It Tong Guo not the gentle phase valve seat of liquid phase valve seat and extraneous pipeline connection.In the present solution, individually by vapor delivery line and liquid phase pipeline
Design is the leakage heat in order to reduce gas cylinder, enhances the adiabatic heat-insulation ability of gas cylinder, gas cylinder is made to have longer hold time.
Preferably, the gentle phase valve seat of liquid phase valve seat is arranged symmetrically in the two sides at the outer front head center of bottle body.In the present solution,
The space of clack box is made full use of, gas-liquid is respectively arranged exterior tubing, avoids contact with interference phenomenon.
Preferably, bottle body is cylindrical shape.
Preferably, the middle position of the gentle phase valve seat of liquid phase valve seat is equipped with built-in cryopump mounting flange mouth.
Compared with prior art, the utility model has the following beneficial effects: by using two mutually independent valve seats
The liquid phase pipeline separate design of the vapor delivery line of gas cylinder and gas cylinder is divided into gas phase valve seat and liquid phase valve seat by structure.From production angle
Degree analysis, avoids the exposed to contact problem of pipeline, and production will not lead to vapor delivery line and liquid because of welding deformation when welding
Phase pipeline short cut with each other contact.It is analyzed from functional perspective, gas cylinder is pushed back in external feed flow stage, gas cylinder filling liquid stage, gas cylinder height
When gas stage, gas cylinder gas phase empty stage, the pipeline not worked is in isolation, thus is avoided that other non-working line contacts
Cryogenic media and the leakage heat problem occurred.It is analyzed from pipeline layout angle, the mutually independent valve seat construction of gas-liquid, in gas cylinder clack box
In exterior tubing placement process, the space of clack box is made full use of, gas-liquid is respectively arranged exterior tubing, avoids contact with interference phenomenon.

Specific embodiment
With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail, it is to be understood that this is practical
Novel protection scope is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1 to Figure 3, according to a kind of automobile gas cylinder of specific embodiment of the present invention, including bottle body 1,
Bottle body 1 includes the gentle interfaces (not shown) of liquid phase interface, it is important to, it is independent on the side wall of bottle body 1 to be provided with liquid
Phase valve seat 11 and gas phase valve seat 12, the gentle interfaces of liquid phase interface pass through liquid phase valve seat 11 and gas phase valve seat 12 and extraneous pipe respectively
Road is connected.So that Outside Vapor pipeline and external liquid phase the pipeline lead since different valve seats respectively, make full use of valve
The space of case, avoids and interferes contact between pipeline the drawbacks of avoiding single valve seat lead.
