Abstract
The compressed natural gas filling machine adopts a pneumatic valve to perform high-medium low-pressure switching device, belongs to a technology of the compressed natural gas filling machine, and is mainly formed by connecting components such as a shell, a one-way valve, a high-pressure stainless steel pipe, a high-medium low-pressure pneumatic switching valve, a mass flow meter, a pipe fitting, a filling gun, a microcomputer controller, a cable and the like.
Description
One, technical field: the utility model relates to a kind of technology of compression natural gas filling machine, and especially the compression natural gas filling machine adopts pneumatic valve to carry out high, normal, basic crush-cutting changing device.
Two, background technology: the compression natural gas filling machine of domestic production at present generally adopts electromagnetic valve to carry out the switching of high, medium and low voltage three road natural fuelses, because there are shortcomings such as weak point in service life, job insecurity and ice block up in electromagnetic valve, and results in hand cramps for the ordinary production of gas station.
Three, summary of the invention: the purpose of this utility model provides the compression natural gas filling machine and adopts pneumatic valve to carry out high, normal, basic crush-cutting changing device, overcome electromagnetic valve and carried out the problem that high, normal, basic crush-cutting changes existence, the purpose of this utility model is achieved in that it is to be formed by connecting by shell, check valve, high pressure stainless steel tube, high pressure hose, the pneumatic transfer valve of high, medium and low voltage, mass flowmeter, air filling gun, microcomputerized controller.The high-pressure pneumatic transfer valve, in calm the anger moving transfer valve, low-pressure pneumatic transfer valve, mass flowmeter, microcomputerized controller be fixed in the shell with screw, support respectively; Three check valves are connected by the high pressure stainless steel tube with the pneumatic transfer valve of high, medium and low voltage respectively; Mass flowmeter one end is connected by the high pressure stainless steel tube with the pneumatic transfer valve of high, medium and low voltage respectively, and the mass flowmeter other end is connected with air filling gun by high pressure stainless steel tube, high pressure hose; Mass flowmeter, the pneumatic transfer valve of high, medium and low voltage are connected with microcomputerized controller by cable respectively; Instrument wind is connected by the pneumatic transfer valve of nylon tube and high, medium and low voltage in the gas station; Three check valves are connected with storage tank in the gas station by the high pressure stainless steel tube respectively again.
When work, air filling gun is with after the automobile gaholder is connected, start filling machine, microcomputerized controller output control signal, open the low-pressure pneumatic transfer valve by instrument wind in the gas station, stand and go up the low pressure natural gas source by injection automobile gaholder such as check valve, low-pressure pneumatic transfer valve, mass flowmeter, air filling guns.Microcomputerized controller is accepted the output signal of mass flowmeter simultaneously, calculates and demonstration.When flow is lower than 3kg/Min, microcomputerized controller output signal, the moving transfer valve of calming the anger in opening.When flow is lower than 2kg/Min, the microcomputerized controller output signal, the moving transfer valve of calming the anger in cutting out opens the high-pressure pneumatic transfer valve.When flow was lower than 1kg/Min, the microcomputerized controller output signal was closed the pneumatic transfer valve of high and low pressure simultaneously, finished the aerating process one time.
Owing to adopt such scheme, add the air valve long service life, working stability, aerating safety, efficient.
Four, description of drawings: Fig. 1 carries out high, normal, basic crush-cutting changing device structural representation for the compression natural gas filling machine adopts pneumatic valve:
Among the figure 1, shell 2, check valve 3, high pressure stainless steel tube 4, high-pressure pneumatic transfer valve 5, in the storage tank in instrument wind 14 in moving transfer valve 6, low-pressure pneumatic transfer valve 7, mass flowmeter 8, high pressure hose 9, air filling gun 10, microcomputerized controller 11, cable 12, nylon tube 13, the gas station, the gas station of calming the anger.
Five, the specific embodiment: in above Fig. 1, high-pressure pneumatic transfer valve 4, in calm the anger moving transfer valve 5, low-pressure pneumatic transfer valve 6, mass flowmeter 7, microcomputerized controller 10 be fixed in the shell 1 by screw, support respectively; Three check valve 2 one ends respectively with high-pressure pneumatic transfer valve 4, in calm the anger moving transfer valve 5, low-pressure pneumatic transfer valve 6 be connected by high pressure stainless steel tube 3, three check valve 2 other ends are connected with storage tank 14 in the gas station by high pressure stainless steel tube 3 respectively again; Mass flowmeter 7 one ends respectively with high-pressure pneumatic transfer valve 4, in calm the anger moving transfer valve 5, low-pressure pneumatic transfer valve 6 be connected by high pressure stainless steel tube 3, mass flowmeter 7 other ends are connected with air filling gun 9 by high pressure stainless steel tube 3, high pressure hose 8; Mass flowmeter 7, high-pressure pneumatic transfer valve 4, in calm the anger moving transfer valve 5, low-pressure pneumatic transfer valve 6 be connected with microcomputerized controller 10 by cable 11 respectively; In the gas station instrument wind 13 by nylon tube 12 respectively with high-pressure pneumatic transfer valve 4, in calm the anger moving transfer valve 5, low-pressure pneumatic transfer valve 6 be connected.
