[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Refer to Figure 1 、 Figure 2 An embodiment provided by the present invention: A valve high-temperature testing machine includes a gas storage tank 1. Gas heaters 2 are respectively arranged on both sides of the gas storage tank 1. The output end of the gas heater 2 penetrates through one side of the gas storage tank 1 and is located inside the gas storage tank 1. Connecting pipes are evenly arranged on the circumferential surface of the gas storage tank 1. The number of connecting pipes is several and their sizes gradually increase from left to right. One end of the connecting pipe is provided with a valve test station 6, and the valve test station 6 matches the connecting pipe. The outer wall of the gas storage tank 1 is provided with heat insulation cotton. A pressure sensor 4 is arranged on one side of the gas storage tank 1. Temperature control sensors 3 are symmetrically arranged on the circumferential surface of the gas storage tank 1. An air inlet pipe is fixedly connected to one side of the gas storage tank 1. An air compressor air source inlet 7 is arranged on one side of the air inlet pipe. A support structure is arranged at the bottom of the gas storage tank 1.

[0022] Specifically, the operation of the gas heater 2 can heat the gas inside the gas storage tank 1. By installing valves of different models on the corresponding valve test stations 6, the air source is input into the gas storage tank 1 through the air inlet pipe through the air compressor air source inlet 7. The gas inside the gas storage tank 1 is circulated with the valve test station 6 through the connecting pipe. The heat insulation cotton is used to prevent the surface of the gas storage tank 1 from scalding the operator. The temperature control sensor 3 is used to monitor the air temperature inside the gas storage tank 1 in real time, and the pressure sensor 4 is used to monitor the pressure data inside the gas storage tank 1 in real time, thereby improving the test efficiency of the valve high-temperature testing machine and solving the problem that the traditional valve high-temperature testing machine can usually only test valves matching its model and has low test efficiency.

[0023] Refer to Figure 1 、 Figure 2, the interior of the connecting pipe communicates with the interior of the gas storage tank 1, and the interior of the intake pipe is connected to the interior of the gas storage tank 1; the support structure includes a base, and support columns are symmetrically and fixedly connected to the top of the base, and the top of the support columns is fixedly connected to the bottom of the gas storage tank 1; a vertical first exhaust pipe is provided at the top of the connecting pipe, one end of the first exhaust pipe is provided with an exhaust port 8, and a solenoid valve is provided on one side of the exhaust port 8; a horizontal second exhaust pipe is provided on one side of the first exhaust pipe, and a manual test valve 9 is provided on one side of the second exhaust pipe; the interior of the first exhaust pipe is connected to the interior of the connecting pipe, and the interior of the first exhaust pipe is connected to the interior of the second exhaust pipe; connecting rods are symmetrically and fixedly connected to the top of the gas storage tank 1, and an electric control cabinet 5 is fixedly connected to one side of the connecting rod; the electric control cabinet 5 is electrically connected to the temperature control sensor 3, the pressure sensor 4, the gas heater 2 and the solenoid valve on one side of the exhaust port 8.

[0024] Specifically, the testing machine is supported by the support structure. Through the operation of the solenoid valve on one side of the exhaust port 8, the gas inside the gas storage tank 1 can be discharged through the exhaust port 8 on the exhaust pipe after the test is completed. Through the manual test valve 9, it is possible to manually test whether the valves on the valve test station 6 of the corresponding connecting pipe are leaking. Through the electric control cabinet 5, the operation and adjustment of the temperature control sensor 3, the pressure sensor 4, the gas heater 2 and the solenoid valve on one side of the exhaust port 8 can be controlled. It can be realized through PLC control. The test time and number of times can be adjusted through the solenoid valve signal, which is convenient and fast. Moreover, various gas valves such as butterfly valves, ball valves, and double eccentric valves of different sizes can be tested through the valve test stations 6 of different sizes. The normal temperature inside the gas storage tank 1 can be adjusted to 220°, so as to simulate the on-site working condition environment, test the seals of the valves, and detect the service life and sealing performance of the valves, thus increasing the practicality of the valve high-temperature testing machine.

[0025] Working principle: When using this valve high-temperature testing machine, different models of valves are installed on the corresponding valve testing station 6. Then, the air source is input into the interior of the air storage tank 1 through the air inlet pipe from the air compressor air inlet 7. Subsequently, through the operation of the gas heater 2, the gas inside the air storage tank 1 can be heated accordingly. Heat insulation cotton is used to prevent the surface of the air storage tank 1 from scalding the operator. The gas inside the air storage tank 1 is made to flow through the connecting pipe to the valve testing station 6. The operation of the temperature control sensor 3 is controlled by the electric control cabinet 5 to monitor the real-time temperature data of the gas inside the air storage tank 1. The operation of the pressure sensor 4 is controlled to monitor the real-time pressure data of the gas inside the air storage tank 1. The operation of the gas heater 2 is controlled to adjust the temperature of the gas inside the air storage tank 1 in real time according to the corresponding requirements. The manual test valve 9 can be used to manually test whether the valves on the valve testing station 6 of the corresponding connecting pipe are leaking. Thus, different-sized valves can be tested accordingly through multiple valve testing stations 6 of different sizes. After the test is completed, the solenoid valve on the exhaust port 8 side is controlled by the electric control cabinet 5 to discharge the gas inside the air storage tank 1 through the exhaust port 8 on the exhaust pipe, thereby completing the life and sealing performance tests of the valves.
