Abstract
The utility model relates to an accessory of a natural gas conveying semitrailer, in particularly to a steel cylinder gas-discharging device for a compressed natural gas conveying semitrailer of a hydraulic substation. The steel cylinder gas-discharging device comprises No.1 to No.8 steel cylinders and is characterized in that: a liquid phase and a gas phase pipeline are connected with the two ends of each steel cylinder, a communicating valve is arranged between a gas charging pipeline and a gas discharging pipeline of two paths of gas phases, and valve locks are arranged at the liquid phases of the No.7 and No.8 steel cylinders. The steel cylinder gas-discharging device also has the following characteristics: two different gas discharging ways can be selected according to the technical conditions of the substation; the gas discharging way is flexible and the gas discharging speed is high; in addition, the normal gas discharging can be ensured.
Description
(1) technical field
The utility model relates to a kind of natural gas transportation semitrailer annex, and particularly a kind of hydraulic pressure substation compressed natural gas conveying semi-trailer steel cylinder unloads device of air.
(2) background technique
Present employed natural gas transportation semitrailer, what the collection tubulature line journey in the Flat Rack Container adopted is that traditional single line unloads gas technology, it is single to unload the gas mode, is unfavorable for guaranteeing to unload normally carrying out of gas when breaking down.
(3) summary of the invention
The utility model is in order to remedy the defective of prior art, provide a kind of unload the gas mode flexibly hydraulic pressure substation compressed natural gas conveying semi-trailer steel cylinder unload device of air.
The utility model is achieved by the following technical solution:
A kind of hydraulic pressure substation compressed natural gas conveying semi-trailer steel cylinder unloads device of air, comprise the 1-8 steel cylinder, it is characterized in that: the steel cylinder two ends are connected with gentle pipeline of liquid phase, fill, unload at the tow channel gas item to be provided with the connection valve between the tracheae line, in the liquid phase injection valve door locked of 7, No. 8 steel cylinders.
The beneficial effects of the utility model are: this hydraulic pressure substation compressed natural gas conveying semi-trailer steel cylinder unloads device of air, can can select two kinds of different gas modes of unloading according to the process conditions of substation, it is flexible to unload the gas mode, and it is fast to unload gas speed, guarantees to unload normally carrying out of gas.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 unloads the structural representation of device of air for the utility model hydraulic pressure substation compressed natural gas conveying semi-trailer steel cylinder.
Among the figure, A is communicated with valve, the locking of B valve.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This hydraulic pressure substation compressed natural gas conveying semi-trailer steel cylinder unloads device of air, comprise the 1-8 steel cylinder, it is characterized in that: the steel cylinder two ends are connected with gentle pipeline of liquid phase, fill, unload to be provided with between the tracheae line at the tow channel gas item to be communicated with valve A, at the liquid phase injection valve door locked B of 7, No. 8 steel cylinders.
This hydraulic pressure substation compressed natural gas conveying semi-trailer steel cylinder unloads device of air, can select two kinds of different technological processes according to the process conditions of substation when unloading gas, a kind of is liquid phase injection valve door locked B with 7, No. 8 steel cylinders, gas item pipeline directly with gas selling machine low, in compress into gas port and connect the high pressure admission mouth of the liquid phase pressure piping of two groups of steel cylinders and gas selling machine connection in addition; Another kind of technology is with the connection valve A connection of two gas item pipelines, is connected on the suction port of single line gas selling machine, 8 steel cylinders is carried out supercharging successively inject, and guarantees to unload on the basis of gas efficient, has increased the flexibility of unloading gas.
