Abstract
A pipeline system of a compressed natural gas filling machine comprises an inlet ball valve, a filter, an electromagnetic valve, a single-way valve and a mass flowmeter. The single-way valve is communicated with the mass flowmeter through an integrated busbar, and the integrated busbar is composed of a four-way connector and four corresponding connection pipes. A standard special device is integrated through a busbar technique, ten bent pipes in an original pipeline are replaced by six bent pipes, pipeline machining difficulty is reduced, and assembling quality is improved. By means of the pipeline system, an assembling process is improved, what is needed is to fasten clamping sleeves at an outlet of the electromagnetic valve with a fixed supporting point and an inlet of the mass flowmeter with a fixed supporting point, and the difficult problem that assembling quality of a clamping-sleeve-type three-way connector is difficult to guarantee when the clamping-sleeve-type three-way connector is installed on a non-force-bearing supporting point is solved.
Description
Technical field
The utility model belongs to gas metering equipment, relates in particular to a kind of autoamtic compressed gas filling machine.
Background technique
CNG filling machine refers to compressed natural gas (CNG) form provides the aerating equipment of fuel to gas-fueled vehicles (NGV).Critical piece comprises frame, entrance ball valve, filter, manual ball valve, solenoid valve, one-way valve, mass flowmenter, pressure transmitter, safety valve, emergent ball valve, Pull breaking ualve, rifle valve, high pressure hose, air filling gun head, intelligent control system etc., wherein pipe-line system as shown in Figure 1, comprising entrance ball valve 1, filter 2, manual ball valve 3, solenoid valve 4, one-way valve 5, tee union 6, mass flowmenter 7.
This pipe-line system is adopted by most of CNG filling machines on market at present, in Fig. 1, dotted line frame choosing part (one-sided) Placement is: between 3 solenoid valves and 3 one-way valves (two ends cutting ferrule is connected), by 3 screw thread ferrule fittings, be connected with bend pipe, between 3 one-way valves and mass flowmenter, by 2 triplet card bell and spigot joints, 2 bend pipes, 2 straight tubes, be connected with 1 screw thread ferrule fitting.In device fabrication process,, easily there is leakage point in this part processing difficulties, reason mainly contain following some: (1) bend pipe quantity is more, compares straight tube, and bend pipe is difficult to guarantee enough accurate adding size in man-hour, angle, difficulty of processing is large, easily, because machining error causes assembling defect, causes leakage.(2) cutting sleeve type three-way joint in pipe-line system is in overhead positions, when fastening cutting ferrule nut owing to there is no the stressed strong point, can cause following two aspect problems: 1. easily make joint bear excessive lateral force, cause that pipeline torsional deformation, cutting ferrule and the fittings body conical surface cannot align, and then cause leaking; 2. when fastening one of them threeway is installed, can cause that other part cutting ferrules are owing to being subject to external force to interfere the leakage that deforms.(3) collar joint quantity is more, and the assembly technology of Bite type fittings is more complicated, requires assembling to have certain technical merit and experience, and assembly quality has much relations with workman's technical merit, working experience, causes possible leakage point also more.
Model utility content
It is for the deficiency in background technique that the utility model is wanted technical solution problem, and the autoamtic compressed gas filling machine that a kind of assembly quality is high, efficiency of assembling is high, the accumulation of error is few pipe-line system is provided.
In order to address the above problem by the following technical solutions: a kind of autoamtic compressed gas filling machine pipe-line system, comprise entrance ball valve, filter, solenoid valve, one-way valve, mass flowmenter, between one-way valve and mass flowmenter, by integral type cylinder manifold, be communicated with, integral type cylinder manifold is comprised of a cross fitting and four corresponding connecting tubes.
Comprise three entrance ball valves in parallel, three filters, six solenoid valves and one-way valve, two mass flowmenters; Each entrance ball valve is communicated with a filter respectively, is connected with respectively two symmetrical solenoid valves on each filter, on each solenoid valve, is equipped with one-way valve, and unidirectional three one-way valves are communicated with a mass flowmenter by integral type cylinder manifold.
Described integral type cylinder manifold is comprised of a cross fitting and three bend pipes, a straight tube, wherein two bend pipes are fixedly connected with three one-way valves respectively with a straight tube, one-way valve is threaded connection with solenoid valve and is communicated with, and another bend pipe is communicated with mass flowmenter.
The utility model adopts the integrated standardized special purpose device of cylinder manifold technology, and 10 bend pipes in original pipeline are reduced to 6, has reduced pipeline processing difficulty, has improved assembly quality.By adopting the utility model, improved assembly technology, only need there iing the fastening cutting ferrule of electromagnetic valve outlet and mass flowmenter inlet of fixed support point, solve cutting sleeve type three-way joint and when installing without the stressed strong point, be difficult to guarantee a difficult problem for assembly quality.Assembling difficulty reduces greatly, has improved efficiency of assembling, during rigger decreased average 1/4; Ferrule fitting is used and reduces, and has reduced potential safety hazard, and overall cost reduces greatly.Through system test data analysis, Product Assembly first-time qualification rate is increased to 99.2% by 95.5%.

Embodiment
As shown in Figure 2, a kind of autoamtic compressed gas filling machine pipe-line system, comprises three entrance ball valves in parallel 1 ', three filters 2 ', six solenoid valves 4 ', six one-way valves 5 ', two mass flowmenters 7 '.Each entrance ball valve is communicated with a filter respectively, is connected with respectively two symmetrical solenoid valves on each filter, on each solenoid valve, is equipped with one-way valve, and unidirectional three one-way valves are communicated with a mass flowmenter by integral type cylinder manifold 8.
Integral type cylinder manifold 8 is comprised of a cross fitting 8-1 and three bend pipe 8-2,8-3,8-5, straight tube 8-4, wherein two bend pipe 8-2,8-3 are fixedly connected with by cutting ferrule with three one-way valves 5 ' respectively with one of them straight tube 8-4, one-way valve 5 ' is threaded connection with solenoid valve 4 ' and is communicated with, and another bend pipe 8-5 is communicated with by cutting ferrule with mass flowmenter 7 '.
Working procedure: autoamtic compressed gas filling machine is to add the equipment of natural gas injection metering to gas-fueled vehicles.High pressure, middle pressure, low pressure three-way connection (pipe) line form autoamtic compressed gas filling machine pipe-line system.Compressed natural gas enters autoamtic compressed gas filling machine with high pressure, middle pressure, low pressure three-way connection (pipe) line respectively, every road pipeline flow through successively entrance ball valve, filter, solenoid valve, one-way valve, mass flowmenter, repid cut-off valve, Pull breaking ualve, high pressure hose, rifle valve, air filling gun head, finally flow into the gas cylinder of filled automobile.When starting aerating, low-voltage solenoid valve energising is opened, and low pressure gas is to the aerating of automobile gas cylinder, when low pressure gas to automobile gas cylinder filling, reach pressure in a basic balance after, intelligent control system is closed low-voltage solenoid valve, opens middle pressure electromagnetic valve, now, calm the anger to the aerating of automobile gas cylinder, until pressure is in a basic balance again, intelligent control system is closed middle pressure electromagnetic valve, opens high-pressure solenoid valve, high pressure air is to the aerating of automobile gas cylinder, until storage pressure reaches 20MPa, close high-pressure solenoid valve, stop aerating.Now show quality, the amount of money, unit price that screen display has added, thereby complete aerating metering process one time.
