Abstract
The utility model discloses a gas unloading hose snapping valve of a CNG (Compressed Natural Gas) gas station and belongs to the technical field of gas stations. The gas station comprises a supercharging device, a gas unloading hose and a pipe type container, wherein the supercharging device is connected with the pipe type container; the gas unloading hose is provided with a snapping valve. According to the gas unloading hose snapping valve of the CNG gas station, the gas unloading hose is provided with the snapping valve so that the snapping valve can be switched off automatically and safely and has no leakage, and a major safety accident is prevented from occurring.
Description
Technical field
The utility model relates to gas station technical field, and particularly a kind of CNG gas station unloads gas flexible pipe Pull breaking ualve.
Background technique
CNG(Compressed Natural Gas, compressed natural gas) substation trailer arrives after CNG air entraining substation, will unload gas flexible pipe be connected with hydraulic substation prying body by ready-packaged joint.After system connects, start hydraulic substation prying body or monitor hydraulic system pressure when low in PLC control system, high-pressure hydraulic pump is started working, PLC automatic control system can be opened the liquid flowing valve of a steel cylinder and the valve of giving vent to anger, high-pressure liquid medium is injected to a steel cylinder, guarantee that in the trailer steel cylinder of CNG substation, gas pressure remains on 20-22Mpa, CNG after CNG high pressure air-out hose enters substation prying body knock out drum, is delivered to CNG filling machine to CNG fuel automobile aerating through high-voltage tube by steel cylinder air outlet.
But this seed stations aerating also exists following problem, when operator or driver's misoperation, thereby can make the gas flexible pipe that unloads between substation trailer steel cylinder and substation prying body be pulled off the situation generation that causes serious accident.
Model utility content
Thereby in order to solve current air entraining substation, unload gas flexible pipe when the misoperation and be pulled off the problem that causes serious accident, a kind of CNG gas station is now provided.Concrete technological scheme is as follows:
A gas station, comprises supercharging device, unloads gas flexible pipe and tubular type shipping container, and described supercharging device connects described tubular type shipping container by the described gas flexible pipe that unloads, described in unload on gas flexible pipe and be provided with Pull breaking ualve.
Preferably, described supercharging device is supercharging sled or discharge column.
Preferably, described Pull breaking ualve is the Pull breaking ualve of steel ball card laminated structure.
Compared with prior art, the CNG gas station that technique scheme provides has the following advantages: by being provided with Pull breaking ualve unloading on gas flexible pipe, when there is misoperation, Pull breaking ualve can disconnect safely automatically and without any leakage, prevent the generation of serious accident.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the CNG gas station structural representation that the utility model provides.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
As shown in Figure 1, the utility model embodiment provides a kind of CNG gas station to unload gas flexible pipe Pull breaking ualve, comprise supercharging device 4, unload gas flexible pipe 5 and tubular type shipping container 1, supercharging device 4 connects tubular type shipping containers 1 by unloading gas flexible pipe 5, unloads and on gas flexible pipe 5, is provided with Pull breaking ualve 2.Wherein, supercharging device 4 is supercharging sled or discharge column.
CNG substation trailer arrives after CNG air entraining substation, will unload gas flexible pipe be connected with hydraulic substation prying body by ready-packaged joint.After system connects, start hydraulic substation prying body or monitor hydraulic system pressure when low in PLC control system, high-pressure hydraulic pump is started working, PLC automatic control system can be opened the liquid flowing valve of a steel cylinder and the valve of giving vent to anger, high-pressure liquid medium is injected to a steel cylinder, guarantee that in the trailer steel cylinder of CNG substation, gas pressure remains on 20-22Mpa, the valve 3 unloading on gas flexible pipe is opened, CNG unloads gas flexible pipe 5 by steel cylinder air outlet through CNG high pressure and enters after the prying body knock out drum of substation, through high-voltage tube, is delivered to CNG filling machine to the aerating of CNG fuel automobile.Unload that Pull breaking ualve 2 on gas flexible pipe 5 can guarantee to guarantee to trigger when danger occurs, moment closure valve, few water clock and the relative little pressure loss.Break when mechanism both can guarantee " ejection escape ", make equipment can be automatically, depart from fast; Before can guaranteeing again to depart from, there is " phase buffer ", while avoiding normal operation, occur " disengaging " affecting normal handling operation.
Wherein Pull breaking ualve 2 is the Pull breaking ualve of steel ball card laminated structure, than the product of similar spring clip laminated structure, break number of times many, by test, find, Pull breaking ualve is applied to gas station and unloads after gas flexible pipe, effectively prevented because people is misoperation the serious accident that driver's misoperation causes discharge column to be pulled off.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
