Abstract
The utility model discloses a centralized blowdown system of an energy-saving hydraulic compressed natural gas (CNG) automobile gas filling substation system, which comprises a CNG main pipeline and is characterized in that the CNG main pipeline is provided with a blowdown pipe which is communicated with the CNG main pipeline. A ball valve is arranged on the blowdown pipe. After being installed by adopting the structure, the blowdown pipe can discharge high-pressure CNG in the CNG main pipeline during maintenance and relieve the pressure of the CNG main pipeline, thereby having protecting effect, and meeting related regulations in the GB-50156 standards.
Description
Technical field
The utility model relates to a kind of refueling equipment, especially relates to the concentrated blowdown system of a kind of energy-conserving hydraulic formula CNG automobile secondary gas filling station system.
Background technique
Energy-conserving hydraulic formula CNG automobile secondary gas filling station, be with auto-control mode, use complete special device, with hydraulic oil liquid, inject the long-tube trailer bottle formula pressurized container that CNG is housed with high pressure, CNG in the container is released,, realize giving the cluster tool that CNG is the refueling of fuel by the gas selling machine in standing through Oil-gas Separation, filtration.Air entraining substation with hydraulic system applications in the natural gas filling station system.Ability to work is Q=2000Nm3/h or Q=1000Nm3/h, operating cost is low, the Q=1000Nm3/h main motor current is 30KW only, the Q=2000Nm3/h main motor current only is 60KW(2 * 30KW), realized automatic control, can regulate power load automatically, realized the economize on electricity low cost movement according to adding tolerance.Maintenance lacks than legacy equipment, moves more stable.Main line is the important component part of energy-conserving hydraulic formula CNG automobile secondary gas filling station, for making things convenient for the care and maintenance of main line, the high pressure CNG in the CNG main line emitted necessitates.
The model utility content
When being maintaining, technical problem to be solved in the utility model provide a kind of energy-conserving hydraulic formula CNG automobile secondary gas filling station system that reliably CNG in the main line is discharged to concentrate blowdown system.
The technical solution of the utility model is as follows: the concentrated blowdown system of a kind of energy-conserving hydraulic formula CNG automobile secondary gas filling station system, comprise the CNG main line, its main points are: described CNG main line is provided with the blow-down pipe that communicates with this CNG main line, on described blow-down pipe ball valve is installed.Adopt above structure, blow-down pipe is installed after, this blow-down pipe can emit the high pressure CNG in the CNG main line when the maintaining, makes its pressure releasing, thereby plays the safety protection effect, has also satisfied the relevant regulations in the GB-50156 standard.
Described ball valve is a fixing ball valve, and effect is a proper functioning of guaranteeing equipment.
Beneficial effect: the utility model can be reliably emits CNG main line mesohigh CNG when the maintaining, thereby plays the safety protection effect, has also satisfied the relevant regulations in the GB-50156 standard; Have be skillfully constructed, simple in structure, implement easily, characteristics such as good reliability.
Description of drawings
Fig. 1 is a structure intention of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
See also Fig. 1: shown in energy-conserving hydraulic formula CNG automobile secondary gas filling station system concentrate blowdown system, comprise CNG main line 1, this CNG main line 1 is positioned at operating platform one side, described CNG main line 1 is provided with the blow-down pipe 2 that communicates with this CNG main line 1, the outlet end of this blow-down pipe 2 is higher than the peak of described CNG main line 1, on described blow-down pipe 2 ball valve 3 is installed.
The above only is preferred embodiment of the present utility model; it is not restriction with the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
