Abstract
The invention pertains to the technical field of tests, and relates to a high-temperature air valve service life test bed used in a high-temperature air valve test. The test bed comprises an air source, a flow adjuster, an electric heater unit, a support for a high-temperature air valve to be tested, a pressure adjuster and a temperature adjuster; a heat exchanger is additionally arranged between the flow adjuster and the electric heater unit; after flowing through the flow adjuster, an air flow firstly enters the cold side inlet of the heat exchanger and then enters into the hot side inlet of the electric heater unit; after flowing through the high-temperature air valve to be tested, hot air flow of the outlet of the electric heater unit arrives at the hot side inlet of the heat exchanger and then arrives at the pressure adjuster from the hot side outlet of the heat exchanger. The test bed eliminates a water-cool heat exchanger of the original system, utilizes the high-temperature air flow of the outlet of the valve to be tested to preheat the normal-temperature air flow entering the electric heater unit and after being preheated, the normal-temperature air flow entering the electric heater unit enters the electric heater unit, thereby reducing electric heating energy consumption by 30 percent to 80 percent.
Description
Technical field
The invention belongs to the experimental technique field, relate to a kind of the high-temperature air valve service life test bed of high-temperature air valve test that be used for.
Background technology
At present, the air register life test rack generally all adopts electrical heating pressurized air simulation high-temperature air valve working pressure, state of temperature, air-flow is cooled to discharge below the pressure governor valve safe working temperature through wanting first water behind the overtesting valve again, so promptly waste water, wasted the heat of discharging air-flow again.
Summary of the invention
The objective of the invention is to propose a kind of not water, do not waste again and discharge the high-temperature air valve service life test bed of air-flow heat.
Technical solution of the present invention is, comprise source of the gas, flow regulation, the electric heater group, tested high-temperature air valve platform position, pressure is regulated and adjustment, between flow regulation and electric heater group, install air heat exchanger additional, air-flow is after flow regulation, be introduced into the cold limit of air heat exchanger inlet, cold limit outlet from air heat exchanger enters the inlet of electric heater group again, the thermal current of the outlet of electric heater group is after being installed in the tested high-temperature air valve on the tested high-temperature air valve platform position, arrive the hot limit of air heat exchanger inlet, arrive pressure again from air heat exchanger hot limit outlet and regulate.Advantage that the present invention has and beneficial effect, the present invention has cancelled the water-cooled exchanging air of discharging the thermal current cooling in the former high-temperature air valve testing table, the high temperature gas flow that utilizes the test valve to export enters the normal temperature air-flow of electric heater by the heat interchanger preheating, carry out the electric heater group again after the normal temperature air-flow that enters electric heater is preheating to uniform temperature, thereby reduced the power consumption that the electric heater group is heated to the normal temperature air of certain flow uniform temperature, reach energy-conservation effect, the high temperature gas flow of testing the valve outlet simultaneously reduces the reliably working that also helps the pressure governor valve by heat interchanger cooling back temperature.Appropriate design or type selecting by heat interchanger can guarantee that delivery temperature is reduced in the pressure governor valve normal working temperature scope, and the electrical heating power consumption reduces by 30%～80%.
