Abstract
The utility model provides a drain pipe for an automobile-used liquefied natural gas bottle. The drain pipe comprises a liquefied natural gas bottle distributing head, a low-temperature stop valve and a low-temperature restrictor valve, which are connected in sequence. The low-temperature stop valve is of a corner form; the low-temperature stop valve comprises a valve cover assembly, a valve rod, a hand wheel, a valve and a valve body, wherein the valve rod is arranged in the valve cover assembly, the hand wheel is arranged at one end of the valve rod, the valve is arranged at the other end of the valve rod, and the valve cover assembly and the valve are arranged in the valve body; a valve body sealing inclined plane are arranged in the valve body; a valve sealing inclined plane is arranged at one end of the valve; and a seal ring is further arranged between the valve body sealing inclined plane and the valve sealing inclined plane. The drain pipe provided by the utility model has the advantages that because the valve body is improved to be of a corner form, the number of transitional joints is reduced, the cost is saved, the installation space is saved, the assembly workload is reduced, the safety factor is improved, and a joint leakage point is avoid.
Description
Technical field
The utility model relates to the Subzero valve field, particularly relates to a kind of Vehicular liquefied natural gas bottle drain pipe.
Background technique
The automobile liquefied natural gas bottle is as a kind of low-temperature heat-insulation pressure container, be designed with bilayer (vacuum) structure, inner bag is used for storing the LNG Liquefied natural gas of low temperature liquid, be tied with multilayer insulant at its outer wall, has superpower heat-shielding performance, chuck (space between the two-layer container) is pumped into high vacuum simultaneously, jointly forms good adiabatic system.The design of shell and support system can be born the relevant external force that vehicle produces in motion.
Existing Vehicular liquefied natural gas bottle drain pipe is equipped with transit joint between cryogenic globe valve and low temperature Restrictor Valves, transit joint is to occupy the installing space position on the one hand, with fashionable dress to join workload also larger, and it is lower leak source, the safety coefficient of joint to occur.
The model utility content
The purpose of this utility model is to provide a kind of higher Vehicular liquefied natural gas bottle drain pipe of leak source, safety coefficient of avoiding occurring joint.
For solving the problems of the technologies described above, the Vehicular liquefied natural gas bottle drain pipe of the utility model comprises: the liquefied natural gas bottle distributing head, cryogenic globe valve and the low temperature Restrictor Valves that connect successively.Described cryogenic globe valve is the corner form.
Described cryogenic globe valve comprises: bonnet assemblies; Valve rod, being arranged in the described bonnet assemblies of described valve rod; Handwheel, described handwheel are arranged on an end of described valve rod; Valve, described valve is arranged on the other end of described valve rod; Valve body, described bonnet assemblies, described valve are arranged in the described valve body.
Be provided with the valve seal inclined-plane in the described valve body.End at described valve is provided with valve sealing inclined-plane.Described valve seal inclined-plane and described valve sealing inclined-plane agree with.Between described valve seal inclined-plane and described valve sealing inclined-plane, also be provided with seal ring.
The Vehicular liquefied natural gas bottle drain pipe of the utility model has reduced transit joint and has saved cost by valve body being improved to the band angle form, saves the installing space position, alleviates the assembling work amount, improves safety coefficient: lacked a joint leak source.
