Abstract
The utility model relates to a pressure release tester of a cooling system expansion kettle, which is characterized by arranging a high-pressure air source. A gas flow adjusting valve and a gas flow indicator are connected in series in a pressure gas output pipeline of the high-pressure air source; the input of an expansion water kettle to be tested is communicated with the output port of the gas flow adjusting valve; the inner cavity pressure of the expansion water kettle to be tested is transferred to a pressure display instrument by a pressure transducer; and the expansion water kettle to be tested is erected in a pond. The utility model is used for pressure release capability tests of a cooling system expansion kettle of an engine, can accurately measure the start pressure, the balance pressure and the corresponding escape gas flow of an expansion kettle pressure cover and lower the test danger.
Description
Technical field
The utility model relates to test unit, and a kind of test unit about engine-cooling system expansion kettle pressure release ability of more specifically saying so is used to measure the opening pressure of expansion kettle pressure cover; Equalized pressure after the unlatching and corresponding emergent gas flow thereof.
Background technology
In the development experiments process of automobile cooling system, the performance that top pressure in the cooling system is set system has very big influence, this pressure is that the boiling point by cooling system decides, and sealing property and withstand voltage properties by engine cooling water jacket, cooling line, heating radiator, expansion kettle ensure realization.
In order to prevent to surpass the damage that set pressure causes system component because of the pressure in the cooling system, on the pressure cover of expansion kettle, all be provided with blowdown valve, when system pressure surpasses setting value, this blowdown valve is opened, anti freezing solution in the cooling system is overflowed with the state of water vapor, thereby stops intrasystem pressure to continue to raise; After blowdown valve is opened fully, the engine light running, the pressure in the cooling system should not surpass setting value and can keep certain gas effusion flow.
At present, the test of cooling system expansion kettle pressure release ability is carried out on test vehicle.The problem that this test method exists comprises: arranged and the restriction of expansion kettle pressure cover structure by the nacelle inner part, can only install pressure unit additional and measure pressure in the expansion kettle on the expansion kettle, can't measure the flow of expansion kettle emergent gas; Expansion kettle pressure inside is to set up by the rising of coolant temperature in the closed circuit cooling system, and the temperature of liquid coolant is subjected to multiple factor restriction and be difficult to accurately control, causes regulating continuously, accurately the pressure in the expansion kettle; The expansion kettle has the risk of breaking under the effect of high temperature coolant (reaching as high as 140 ℃) and pressure (gauge pressure can reach 1.8bar), the scald accident easily takes place.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of cooling system expansion kettle pressure release ability test device is provided, so that can accurately measure opening pressure and the equalized pressure and the corresponding emergent gas flow thereof of expansion kettle pressure cover, and reduce empirical risk.
The utility model technical solution problem adopts following technical scheme:
The design feature of the utility model cooling system expansion kettle pressure release ability test device is, high-pressure air source is set, in the pressed gas output pipe of high-pressure air source, series connection is provided with gas flow regulating valve and gas meter, the input port of tested expansion kettle communicates with the output port of gas flow regulating valve, and the chamber pressure of tested expansion kettle is delivered in the pressure display instrument table by pressure unit; Described tested expansion kettle stands in the pond.
Design feature of the present utility model is that also described high-pressure air source is pressurized air or N2 gas cylinder, at the output mouth of pipe of described gas cylinder reduction valve is set.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model does not need special equipment to implement, and has effectively reduced the experiment work amount, has saved testing expenses;
2, the utility model can be measured opening pressure and the equalized pressure and the corresponding emergent gas flow of expansion kettle pressure cover accurately and fast, and can reduce empirical risk.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure: 1 gas cylinder, 2 reduction valve, 3 gas flow regulating valves, 4 gas meters, 5 ponds, 6 tested expansion kettles, 7 swelling water pot lid, 8 pressure units, 9 digital displaying meters.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment
Referring to Fig. 1, high-pressure air source 1 is set in the present embodiment is gas cylinder, can be pressurized air or N
2Nitrogen, the output mouth of pipe at gas cylinder is provided with reduction valve 2, in the pressed gas output pipe of high-pressure air source 1, series connection is provided with gas flow regulating valve 3 and gas meter 4, the input port of tested expansion kettle 6 communicates with the output port of gas flow regulating valve 3, the chamber pressure of tested expansion kettle 6 is delivered in the pressure display instrument table 9 by pressure unit, and tested expansion kettle 6 stands in the pond 5.
During test, the tested expansion kettle in the cooling system 6 is pulled down from vehicle, at pressurized air or N
2Insert gas pressure reducer 2 and gas flow regulating valve 3 on the gas cylinder 1, the output terminal of flow control valve 3 and the tested expansion kettle 6 of gas meter and engine-cooling system are joined together to form sealing with flexible pipe; Again with flexible pipe with the measuring junction of pressure unit 8 and tested expansion kettle 6 UNICOMs, and guarantee that the sealing of pipeline, the output signal of pressure unit 9 insert digital displaying meter with real-time demonstration institute measuring pressure value; Other interface on the tested expansion kettle 6 is sealed with plug, at last tested expansion kettle is uprightly placed pond 5, and cover protective shield.Progressively strengthen pressure and the flow that enters expansion kettle gas by adjusting reduction valve and flow control valve, note the pressure that the expansion kettle begins pressure transmitter measurement after the pressure release, read by digital displaying meter, and measure the effusion flow of gas by gas meter, when having tangible ascendant trend, the pressure of tested expansion kettle 6 and gas effusion flow do not stop.
Regulate reduction valve 2 and gas flow regulating valve 3 blowdown valve in swelling water pot lid 7 and begin pressure release, at this moment have bubble to emerge in the pond 5, note the registration of gas meter 4 and the registration of digital displaying meter 9; Continuation adjusting reduction valve 2 and flow control valve 3 strengthen the gaseous tension and the flow that enter tested expansion kettle 6 and no longer increase until the registration of gas meter 4 and the registration of digital displaying meter 9, note the registration of flowmeter 4 this moment and the registration of digital displaying meter 9.
