Abstract
The utility model relates to a vehicle air supply pipeline pressure holding and leak hunting device for a fuel battery automobile. Compressed air is linked into an air distributor of a supercharger through a drive air dealing system and comes into the supercharger to drive a supercharger plunger to have a reciprocating motion. Nitrogen is connected with a high pressure nitrogen tank through a nitrogen access, flows through an air inlet ball valve, a non-return valve and a filter to come into the supercharger. After a compaction of the plunger, the nitrogen outflows from a pressurized air outlet through a precise pressure gauge to form three ways, wherein one way is connected with an unloading ball valve, one way is connected with an over pressure shut-off valve and one way comes through an outlet ball valve, a high pressure metal flexible pipe to connect with an air-adding gun which is connected with an air-receiving joint of the fuel battery automobile to have the pressure holding and leak hunting test for the vehicle air supply pipeline to be pressurized to a desired pressure. When an air pressure is pressurized to a setting pressure of the overpressure shut-off valve, the overpressure shut-off valve switches off the drive air and the device ceases the work of the supercharger and gradually compresses to prevent an over high pressure making damage to staffs and equipments on the moment of having a leakage point through the control of the overpressure shut-off valve.
Description
Technical field
The utility model relates to vehicle-mounted supply air line pressurize of a kind of fuel cell car and leakage detection apparatus.
Background technology
At present, known gas cylinder generally all is to do hydraulic pressure test, but does not also have special apparatus and method for for the pressurize test of supply air line in the fuel-cell vehicle on-board high-voltage air supply system.The novel vehicle-mounted gas cylinder gas storage pressure of fuel-cell vehicle will arrive the height as 35MP now, the working pressure of supply air line is also corresponding will to reach 35MP, though gas cylinder and parts dispatch from the factory pressure test is arranged all, but at the tie point place that the high-pressure air feed pipeline connects, often, test with leak detection so must carry out pressurize to the supply air line of installing sometimes because of the improper leak point that exists of installation.Transport pressure based on the present gas cylinder of China must not surpass 14.5MP ± 5% (20 ℃), has not satisfied requirement for this kind of pressurize source of the gas of high workload forced air supply pipeline more.
Summary of the invention
Technical problem to be solved in the utility model provides vehicle-mounted supply air line pressurize of a kind of fuel cell car and leakage detection apparatus, this device can satisfy the pressurize and the leak detection of high-pressure air feed pipeline, prevent that hypertonia from causing leakage, cause that pipeline takes off to split the staff is brought danger and to the infringement of equipment.
The technical scheme that its technical matters that solves the utility model adopts is: the pressurize and the leakage detection apparatus of the vehicle-mounted supply air line of a kind of fuel cell car comprise driving pipeline, air inlet pipeline, pneumatic booster, outlet pipe.The gases at high pressure of outlet pipe for coming out from pneumatic booster, flow out by pressure duct, divide three the tunnel by precision pressure gauge, one the tunnel connects the emptying ball valve, and one the tunnel connects the overvoltage stop valve, and the overvoltage stop valve is connected on the driving gas simultaneously, also have one the tunnel successively through outlet ball valve, high-pressure metal flexible pipe, be connected to air filling gun, air filling gun is connected to the head of being bullied of fuel-cell vehicle, comes to vehicle-mounted supply air line pressurize of fuel-cell vehicle and leak detection.
Air inlet pipeline is a gas by the nitrogen joint by the high-pressure metal flexible pipe, enter pneumatic booster through boost gauge, air inlet ball valve, retaining valve, filtrator successively.
Driving pipeline is the gas distributor that pressurized air passes through gas fast joint, reinforced plastics flexible pipe, variable valve, driving gas tensimeter, moisture trap, connection air inlet body supercharger, enters supercharger and promotes the intensifier piston to-and-fro movement.
The utility model beneficial effect is: control by the overvoltage stop valve, progressively pressurization prevents when leakage point is arranged, hypertonia causes the injury to personnel and equipment, adopt pneumatic booster to need not power supply simultaneously, retaining valve prevents gas backstreaming, and there is the infringement that causes to equipment in molecule in the filtrator prevention gas, and precision pressure gauge is convenient to operating personnel's judgement in time and is had or not leakage point to exist, air filling gun is used for being connected with the fuel-cell vehicle supply air line fast, raises the efficiency.
