Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiments of the present invention relate to a kind of 80% limit and fill durability test bench, be used for the serviceability test that LPG Vehicular liquefied petroleum gas gas cylinder pile-up valve 80% limit is filled and filled, require the testing table of the special use of regulation design according to " GB18299 automobile-use liquefied petroleum gas steel cylinder pile-up valve ", this testing table comprises electrical control part and hydraulic pressure part, and described electrical control part comprises control system and computer display system; Described control system is used to control the operation of described testing table; Described computer display system is used to show test figure and result; Described hydraulic pressure partly comprises gas drive liquid pump, accumulator, reduction valve and centrifugal water pump; Described centrifugal water pump one end links to each other with water tank, and the other end links to each other with liquefied petroleum gas steel cylinder; Be provided with liquid level sensor in the described liquefied petroleum gas steel cylinder; Described gas drive liquid pump one end links to each other with described water tank, and the other end links to each other with described accumulator; Described accumulator links to each other with the tested valve of described liquefied petroleum gas steel cylinder by described reduction valve; Described tested valve two ends are provided with pressure unit; Be connected with tee ball valve on the described tested valve; Described tee ball valve links to each other with flowmeter.Wherein, the gas drive liquid pump drives by air; The volume of liquefied petroleum gas steel cylinder is 50L; The flow of centrifugal water pump is 200L/min; Flowmeter adopts high precision flow; Control system is the PLC control system.
Shown in Figure 1 is the fundamental diagram of this testing table.This testing table is that water is that medium passes through tested valve (being automobile-use liquefied petroleum gas steel cylinder pile-up valve) and simulates Vehicular liquefied gas cylinder to standard 50L and fill repeatedly, the filling process of simulated solution gasification, the requirement of the automobile-use liquefied petroleum gas steel cylinder pile-up valve serviceability test of checking automobile-use liquefied petroleum gas steel cylinder pile-up valve whether to satisfy to stipulate among the GB18299 by various detection components and parts, this testing table is mainly tested as follows:
When 1) liquid level of test in steel cylinder reached 70%-80%, 80% overfill-limiting device of automobile-use liquefied petroleum gas steel cylinder pile-up valve can be closed automatically.In order to improve device frequency, first centrifugal water pump 19 with the big flow of 200L/min, simulate Vehicular liquefied gas cylinder water-filling for standard 50L, detect bottle interior liquid level when 60% left and right sides by liquid level sensor 22, close centrifugal water pump 19, by gas drive liquid pump 6 (maximum flow is 14.81L/min) water is pressurized to accumulator 12 then, then by reduction valve 16 and tested automobile-use liquefied petroleum gas steel cylinder pile-up valve water-filling in liquefied petroleum gas steel cylinder, when liquid level reaches 70%-80% in bottle, tested automobile-use liquefied petroleum gas steel cylinder pile-up valve can cut out automatically, by centrifugal water pump 19.1 50L is simulated Vehicular liquefied gas cylinder water then and draw back water tank, circulate with this, cycle index can be presented on the computer monitor in real time, test finishes automatically when cycle index reaches 6000 times, and its test frequency can be made as 1.5 times/min.
2) in off-position, when pile-up valve two ends pressure reduction was 0.7MPa, the 80% overfill-limiting device speed of filling of testing was no more than 500ml/min.By regulating reduction valve 16 its top hole pressure is transferred to 0.7MPa, forward tee ball valve 23 to flowmeter 21 sides, measure tested valve rate of discharge this moment by flowmeter 21, this data in real time is presented on the computer monitor, judge with this whether tested valve 80% overfill-limiting device is qualified.
When 3) pressure differential of test at the flow-limiting valve two ends of pile-up valve surpassed 0.1MPa, flow-limiting valve should be closed automatically.After closing, under the pressure reduction of 0.1MPa, the leakage flow of liquefied petroleum gas (LPG) should not surpass 1000ml/min; By regulating reduction valve 16 its top hole pressure is transferred to 0.1MPa, forward tee ball valve 23 to flowmeter 21 sides, measure tested valve rate of discharge this moment by flowmeter 21, this data in real time is presented on the computer monitor, judge with this whether the tested valve flow-limiting valve is qualified.
This shows that the present invention is that medium is simulated Vehicular liquefied gas cylinder by tested valve to standard 50L and filled the filling process of simulated solution gasification repeatedly with water.When loop test, thereby show the progress of the current test of cycle index quicklook ground understanding in real time, and when reaching test number (TN), controlling shutdown automatically by the PLC control system by computer display system; Adopt the combination of accumulator and reduction valve, realize the pressure reduction at the tested valve of minute adjustment two ends, make its precision be controlled at ± 0.3%FS in, and show in real time that by computer display system warranty test pressure satisfies the regulation of GB18299 standard fully; Adopt high precision flow to measure the valve outlet port flow, and show automatically, can judge whether conformance with standard requirement of tested valve fast; Use liquid level sensor measure analog bottle internal volume, and show in real time, guaranteed that 80% limit fills by computer display system.
