[0028] The guide tube 8 is installed on the mounting plate 7, and the mounting plate 7 is slidably set inside the test chamber 3. During operation, the position of the guide tube 8 can be effectively adjusted according to the size of the high-temperature valve body 10, ensuring that the guide tube 8 and the connecting pipe 12 can only meet the overall installation requirements of high-temperature valve bodies 10 of different sizes, and ensuring that subsequent testing work can proceed smoothly.

[0029] A gas distribution pipe 11 is embedded at the bottom of the test chamber 3. The gas distribution pipe 11 is hollow inside and has gas distribution holes 111 at the top. Several gas distribution holes 111 are provided and are equidistantly arranged at the top of the gas distribution pipe 11. An outlet pipe 13 is installed in the middle section of the connecting pipe 12. The gas distribution pipe 11 and the outlet pipe 13 are connected. The two ends of the high temperature valve body 10 are connected and fixed by the mounting plate 9. A display screen 15 and a button 16 are installed on the top of the test platform body 1. A pressure gauge 14 is installed on the side of the test box 2 and is connected to the inside of the test chamber 3.

[0030] By coordinating the gas distribution pipe 11, the gas distribution hole 111, and the gas outlet pipe 13, the butterfly valve at the gas outlet pipe 13 can be opened, allowing some steam to enter the test chamber 3 through the gas outlet pipe 13 and the gas distribution hole 111 on the gas distribution pipe 11. This adjusts the overall temperature and humidity inside the test chamber 3, thereby testing the overall high-temperature resistance, corrosion resistance, and wear resistance of the high-temperature valve body 10.

[0031] Reference Figure 1-4 As shown, a connecting post 17 is fixedly fixed to the end of the sealing door 4 away from the hinge. A tensioning cavity is provided on the outer side of the test box 2. A tensioning assembly 18 is installed in the tensioning cavity. The connecting post 17 and the tensioning assembly 18 are fixed together. The tensioning assembly 18 includes a lead screw 21 rotatably disposed in the tensioning cavity. A sliding block 19 is sleeved on the lead screw 21. The sliding block 19 and the lead screw 21 are threaded together. A snap ring 20 is rotatably disposed on the sliding block 19. A snap ring 20 is provided on the snap ring 20 for the connecting post 17 to snap into. An embedded plate 22 is installed on the test box 2 to assist the rotation of the lead screw 21. An embedded plate 22 that drives the lead screw 21 to rotate is rotatably embedded on the outer side of the test box 2. A worm gear 221 is fixed on one side of the embedded plate 22. A worm wheel 211 is fixed on the end of the lead screw 21 facing the worm gear 221. The worm wheel 211 and the worm gear 221 are connected for transmission.

[0032] Through the cooperation between the protective pad 5 set on the sealing door 4, the sealing ring 6 on the test chamber 2, the connecting column 17, and the tensioning assembly 18, the sealing door 4 can be installed on the test chamber 2 during testing. The connecting column 17 is snapped into the snapping hole of the snapping ring 20. The embedded plate 22 is rotated, which drives the worm 221 to rotate as a whole. The worm 221 and the worm wheel 211 cooperate to drive the transmission, thereby causing the worm wheel 211 to rotate as a whole, which in turn causes the lead screw 21 to rotate as a whole. The lead screw 21 and the sliding block 19 are threaded together, thereby causing the sliding block 19 to move towards the embedded plate 22. During the movement of the sliding block 19, the snapping ring 20 is moved as a whole, thereby assisting in the tensioning of the connecting column 17. This completes the overall sealing treatment of the test chamber 3 by the sealing door 4, ensuring a good sealing effect and ensuring that the test chamber 3 has a corresponding test environment during testing, ensuring that the test can proceed smoothly.

[0033] A protective pad 5 is installed on the side of the test chamber 3 facing the test box 2, and a sealing ring 6 is installed on the side of the test box 2 facing the sealing door 4. The protective pad 5 and the sealing ring 6 cooperate to seal. The vertical cross section of the sealing ring 6 is hexagonal honeycomb. Three sealing rings 6 are stacked. By setting up multiple layers of sealing rings 6, it can be ensured that they cooperate with the protective pad 5 during operation to improve the overall sealing effect.

[0034] Working principle:

[0035] When the high-temperature valve body 10 needs to be tested, the two ends of the high-temperature valve body 10 are respectively bolted to the mounting plate 9 of the guide pipe 8 and the connecting pipe 12. Depending on the overall length of the high-temperature valve body 10, the guide pipe 8 can be moved to the designated position. After the high-temperature valve body 10 is installed, the sealing door 4 is covered and installed on the test box 2, and the connecting column 17 is snapped into the snap hole of the snap ring 20. The mounting plate 22 is rotated, which drives the worm 221 to rotate as a whole. The worm 221 and the worm wheel 211 cooperate to drive the transmission, thereby causing the worm wheel 211 to rotate as a whole, which in turn causes the lead screw 21 to rotate as a whole. The lead screw 21 and the sliding block 19 are threaded together, thereby causing the sliding block 19 to move towards the mounting plate 22 as a whole. During the movement of the sliding block 19, the snap ring 20 is moved as a whole, thereby providing auxiliary tightening treatment for the connecting column 17.

[0036] During operation, the steam generator is started, and the steam gas flows through the connecting pipe 12 into the high-temperature valve body 10 for high-temperature and high-pressure testing. In operation, the butterfly valve at the outlet pipe 13 can be opened to allow some steam to enter the test chamber 3 through the outlet pipe 13 and the air distribution hole 111 on the air distribution pipe 11, thereby adjusting the overall temperature and humidity inside the test chamber 3, and thus testing the overall high-temperature resistance, corrosion resistance and wear resistance of the high-temperature valve body 10.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
