Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, a kind of new type high temperature valve test device, it is characterized in that, comprise air compressor 1, heating furnace 2, coiled pipe 3, first adapter 19, torque sensor 6, electric actuator 7, second adapter 20 and surge tank 11, described air compressor, coiled pipe 3, first adapter 19, valve 9 to be measured, second adapter 20 is connected in turn with surge tank 11, described coiled pipe 3 is in heating furnace 2, described first adapter 19 is provided with electric check valve 4 and flowmeter 5, described torque sensor 6 connects the valve rod of valve 9 to be measured and the axle head of electric actuator 7 respectively by shaft coupling, on electric actuator 7 and torque sensor 6 stationary work-table, described first adapter 19, second adapter 20 is respectively equipped with connecting pipe, described connecting pipe is provided with differential manometer 8.Described heating furnace 2 wall at least comprises three holes varied in size, among three, position is up to viewport 16, middle is burning added holes 17, position is minimum is waste sludge discharge hole 18, described coiled pipe 3 is in above burning added holes 17, and the caliber of described first adapter 19, second adapter 20 is greater than the caliber of described coiled pipe 3.
Valve 9 to be measured is connected by short circuit part 10 respectively with between the first adapter 19, second adapter 20, and short circuit part 10 is welded with the reducing steel tube of flange for two ends, is applicable to the valve of different bore.In an embodiment, fixed on the table by valve to be measured, because specification is different, its physical dimension also there are differences, and uses short circuit part to connect valve and take over and just can solve problem.Also be provided with pressure transducer 12 above described surge tank 11, bottom is provided with discharge pipe, and pipeline is also provided with stop valve 13.
From fuel added holes, coal is added in the present invention, pass into enough air simultaneously, make its Thorough combustion.Start air compressor, make the air pressure in coiled pipe rise to 0.3MPa, pressure-air, through coal combustion, is heated to test temperature 650 DEG C.Long-distance Control electric check valve, makes high temperature and high pressure gas enter valve.
In the present embodiment, the content measurement of test valve comprises resistance coefficient test, torsional performance test, discharge characteristic test.The resistance coefficient of valve depends on the size of valve, structure and cavity shape.Test pressure is 0.3MPa, needs the amount recorded to be flow (m3/s) in pressure reduction (MPa) before and after valve relative opening degree (%), valve, pipe.By the aperture of the slow control valve of electric actuator, scope is from 0 ~ 100%(relative opening degree), then by the above-mentioned data to be measured of capture card Real-time Collection, after machine analysis and arrangement, draw the resistance coefficient figure under test valve different opening as calculated.
In the torsional performance test process of valve, the amount that needs record is the angle (°) of valve opening, and the moment of torsion (N.m) of corresponding aperture lower valve rod.On capture card, the angle variation range of valve electric actuator to be measured is limited to 0 ~ 90 °, the angle of rotating in by-pass valve control opening-closing process on computers, thus obtain the torque value under each angle, the aperture-torque diagram of valve to be measured after software analysis arranges.
