[0002] In the prior art, most traditional high-temperature valve detection methods directly heat the outside of the valve, which cannot simulate the damage of high-temperature fluid to the internal sealing packing of the high-temperature valve during movement, resulting in inaccurate internal heating detection of the high-temperature valve.

[0003] For example, the "high-temperature valve internal heating detection device" disclosed in the Chinese invention patent (publication number: CN111060550A) discloses in its specification: In the fluid conveying system, the valve is an indispensable control component, which mainly has the functions of adjustment, diversion, backflow prevention, cut-off, diversion, etc. Valves are widely used in industrial and civil fields. High-temperature valves are a more commonly used type of valves. In the production process of high-temperature valves, it is necessary to perform high-temperature detection on the sealing packing in the valve to prevent the melting of the packing when conveying high-temperature fluids, resulting in problems such as reduced sealing performance. In the prior art, most traditional high-temperature detection of valves directly heats the outside of the valve, resulting in the inability to effectively simulate the damage of the high-temperature fluid to the sealing packing during the detection process.

[0017] Compared with the prior art, the present invention has the following beneficial effects: In the scheme of this application: 1. In order to solve the problem that most of the traditional high-temperature detection of valves in the prior art directly heats the outside of the valve, which cannot simulate the damage of the high-temperature fluid to the internal sealing packing of the high-temperature valve during the movement, thereby causing inaccurate internal heating detection of the high-temperature valve, the present application uses the detection component set up to drive the piston plate to move under the rotation of the driving roller.

[0021] As described in the background art, conventional high temperature valve detection mostly directly heats the outside of the valve, which cannot simulate the damage of the high temperature fluid to the internal sealing packing of the high temperature valve during movement, resulting in inaccurate internal heating detection of the high temperature valve.

[0022] In order to solve this technical problem, the present invention provides a high-temperature valve internal heating detection device, which is applied to internal heating detection.

[0023] Specifically, please refer to Figure 1-Figure 11 The high temperature valve internal heating detection device specifically includes: A base 1 and a high-temperature valve 6, a detection seat 101 and a fixed seat 102 are fixedly installed on the top of the base 1, a fixed plate 107 is fixedly installed on the top of the detection seat 101, a conveying tank 103 is fixedly installed on the top of the fixed seat 102, an assembly roller 104 is fixedly installed on the outer wall of the conveying tank 103 located on one side of the detection seat 101, the interior of the assembly roller 104 is hollow and communicated with the interior of the conveying tank 103, a clamping component 2 capable of clamping and fixing the high-temperature valve 6 is arranged between the assembly roller 104 and the fixed plate 107, the displacement of the clamping component 2 can make the high-temperature valve 6 communicate with or seal the conveying tank 103, and a driving component 7 capable of driving the clamping component 2 to displace is arranged inside the detection seat 101; The detection component 3 can simulate the damage and seal detection of the internal sealing packing of the high-temperature valve 6 by the high-temperature fluid. The detection component 3 includes a tank plate 310 rotatably mounted on the side of the conveying tank 103, a perforated roller 311 is fixedly mounted on the outer wall of the tank plate 310 inside the conveying tank 103, a driving roller 301 is fixedly mounted on the end of the perforated roller 311, and a reciprocating screw groove is opened on the outer wall of the driving roller 301, a piston plate 302 is meshed and slidably mounted on the outer wall of the driving roller 301, and the inner sliding plate 302 of the driving roller 301 located on the side of the assembly roller 104 is fixedly mounted on the outer wall of the driving roller 301. A moving tube 303 is installed, and a plurality of protrusions 304 are installed in an array on the outer wall of the moving tube 303.

The back and forth movement of the piston plate 302 can squeeze and transport high-temperature fluid and detection gas into the high-temperature valve 6 respectively. A reflux component 4 capable of recovering the high-temperature fluid is provided on the fixed plate 107.

[0024] The high-temperature valve internal heating detection device provided by the present invention is designed to solve the problem that most of the traditional high-temperature detection of valves in the prior art directly heats the outside of the valve and cannot simulate the damage of the high-temperature fluid to the internal sealing packing of the high-temperature valve during movement, thereby causing inaccurate internal heating detection of the high-temperature valve. The present application drives the high-temperature valve 6 to move from the initial position to the detection position by setting the cooperation of the clamping component 2 and the driving component 7. At the same time, the high-temperature valve 6 is opened to communicate with the inside of the conveying tank 103, and the driving roller 301 fixedly connected thereto is driven to rotate synchronously under the rotation of the tank plate 310.

With the cooperation of the reflux component 4 and the drive component 7, the high-temperature fluid can drive the high-temperature valve 6 to close, and the piston plate 302 is driven by the drive roller 301 to displace in the opposite direction, thereby squeezing the detection gas inside the conveying tank 103 to the inside of the drive roller 301, so that the moving tube 303 is displaced into the channel connecting the assembly roller 104 and the conveying tank 103, so that the drive roller 301 can be connected with the assembly roller 104, and under the continuous displacement of the piston plate 302, the slide plate 306 will be displaced to release the seal of the moving tube 303, so that the drive roller 301 is connected with the assembly roller 104, so that the detection gas enters the high-temperature valve 6, and the high-temperature valve 6 is tested for sealing. When the sealing performance of the high-temperature valve 6 meets the standard, the high-temperature valve 6 can be displaced under the continuous pressure of the piston plate 302, otherwise the high-temperature valve 6 cannot be displaced to the initial position, thereby improving the accuracy of the internal thermal detection of the high-temperature valve 6.

[0029] The high-temperature valve internal heating detection device provided by the present invention is designed to solve the problem that most of the traditional high-temperature detection of valves in the prior art directly heats the outside of the valve and cannot simulate the damage of the high-temperature fluid to the internal sealing packing of the high-temperature valve during movement, thereby causing inaccurate internal heating detection of the high-temperature valve. The present application drives the high-temperature valve 6 to move from the initial position to the detection position by setting the cooperation of the clamping component 2 and the driving component 7. At the same time, the high-temperature valve 6 is opened to communicate with the inside of the conveying tank 103, and the driving roller 301 fixedly connected thereto is driven to rotate synchronously under the rotation of the tank plate 310.

When the sealing performance of the high-temperature valve 6 meets the standard, the high-temperature valve 6 can be displaced under the continuous pressure of the piston plate 302, otherwise the high-temperature valve 6 cannot be displaced to the initial position, thereby improving the accuracy of the internal thermal detection of the high-temperature valve 6.

[0030] Specifically, by starting the servo motor 701, the reciprocating screw 702 is meshed with the ball screw sleeve 704 to drive the clamp ring 201 to move, thereby moving the high-temperature valve 6 from the initial position to the detection position. During the displacement process, the hand wheel 603 and the wave plate 710 can be meshed, thereby driving the hand wheel 603 to rotate and open the high-temperature valve 6. Then, by starting the servo motor 315, the small gear 316 and the large gear 317 are meshed to drive the tank plate 310 to rotate, thereby driving the piston plate 302 to move toward the side of the assembly roller 104, thereby squeezing the high-temperature liquid inside the conveying tank 103 into the high-temperature valve 6, simulating the high-temperature fluid on the sealing packing inside the high-temperature valve 6. The damage, the high temperature fluid flows into the bellows 401 after passing through the high temperature valve 6, and then the high temperature fluid is recovered by the reflux pipe 402 and sent to the liquid storage chamber 105. When the high temperature fluid flows into the liquid storage chamber 105, it will drive the water impeller 709 to rotate, thereby driving the disc 706 to rotate. The teeth 707 fixedly installed on the disc 706 and the rack 708 fixedly installed on the outer wall of the clamping roller 203 are meshing designs, so that the clamping roller 203 can be displaced to the initial position. With the cooperation of the hand wheel 603 and the wave plate 710, the high temperature valve 6 can be closed. At the same time, when the piston plate 302 is displaced to the side of the assembly roller 104, the cavity on the side of the air duct 308 is in a suction state, thereby displacing the sliding plug 313, so that The gas storage chamber 106 is connected to the inside of the delivery tank 103, so that the helium stored in the gas storage chamber 106 can be sucked into the delivery tank 103. When the high-temperature valve 6 is in a closed state, the driving roller 301 can simultaneously drive the piston plate 302 to move in the opposite direction, squeeze the detection gas to the inside of the driving roller 301, and at the same time, the piston plate 302 can suck the cavity on one side of the liquid conduit 309. At this time, part of the high-temperature fluid retained in the assembly roller 104 can flow back to the delivery tank 103. When a certain negative pressure is reached, the one-way valve 312 provided at the end of the liquid conduit 309 opens, so that the liquid storage chamber 105 is connected to the delivery tank 103, and the high-temperature fluid in the liquid storage chamber 105 is sucked into the delivery tank 103. 3, for the next high-temperature valve 6 detection standby, under the continuous reverse displacement of the piston plate 302, the detection gas can drive the moving tube 303 to move into the channel connecting the assembly roller 104 and the conveying tank 103. When the pressure reaches a certain intensity, the slide plate 306 will be displaced to release the seal of the moving tube 303, so that the driving roller 301 is connected with the assembly roller 104, so that the detection gas enters the high-temperature valve 6, and the high-temperature valve 6 is tested for sealing. When the sealing performance of the high-temperature valve 6 meets the standard, the high-temperature valve 6 can be displaced under the continuous pressure of the piston plate 302, otherwise the high-temperature valve 6 cannot be displaced to the initial position, thereby improving the accuracy of the internal heat detection of the high-temperature valve 6.

[0031] Embodiment 2 further optimizes the high-temperature valve internal heating detection device provided in Embodiment 1. Specifically, Figure 6-Figure 9 As shown, the rigid detection component 5 includes a detection roller 501 slidably installed inside the assembly roller 104, a reset spring 3 510 is fixedly installed between the detection roller 501 and the inner wall of the assembly roller 104, the outer wall of the detection roller 501 covers a limit sleeve 502 slidably installed, the outer side of the limit sleeve 502 is fixedly installed with a flange 517, and a reset spring 2 507 is fixedly installed between the outer wall of the flange 517 and the outer wall of the detection roller 501, a chamber 516 is formed between the inner wall of the assembly roller 104 and the outer walls of the detection roller 501 and the limit sleeve 502, a plurality of through holes 511 are arranged in an array on the outer wall of the assembly roller 104 on one side of the clamping ring 204 and are connected to the chamber 516, a plurality of sealing rods 512 are installed in an array on the outer wall of the clamping ring 204 on one side of the clamping roller 203 and are designed corresponding to the plurality of through holes 511, and a plurality of sealing rods 512 are fixedly installed on the outer wall of the limit sleeve 502 There are multiple L-shaped rods 503, and sealing plugs 504 are fixedly installed at the ends of the multiple L-shaped rods 503. A sliding plug 505 is slidably installed in the sealing plug 504. A tension spring 506 is fixedly installed between the outer wall of the sliding plug 505 and the inner wall of the sealing plug 504. The outer wall array of the detection roller 501 is penetrated by a plurality of assembly holes 518, and detection needles 513 are piston-slidably installed inside the multiple assembly holes 518. A reset spring 514 is fixedly installed between the outer wall of the detection needle 513 and the inner wall of the assembly hole 518. The outer wall array of the limit sleeve 502 is penetrated by a plurality of docking holes 515 and is designed to correspond to the plurality of assembly holes 518. A water impeller 508 is rotatably installed inside the detection roller 501. Auger blades 509 are fixedly installed on both sides of the axis of the water impeller 508 and penetrate the inner wall of the detection roller 501 to communicate with the chamber 516.

[0032] By setting the detection roller 501 and the limit sleeve 502, the limit sleeve 502, under the action of the reset spring 2 507, causes the docking hole 515 on the limit sleeve 502 and the assembly hole 518 on the detection roller 501 to be misaligned, so that the detection needle 513 installed in the piston sliding manner inside the assembly hole 518 can be locked, and a flexible pressure-sensitive sheet is arranged in the assembly hole 518, and an indicator light is arranged on the base 1. The flexible pressure-sensitive sheet and the indicator light are electrically connected. Under the drive of the servo motor 1 701, the clamping assembly 2 is displaced. When the high-temperature valve 6 is displaced to the detection position, the sealing rod 512 fixedly installed on the outer wall of the clamp ring 204 can be aligned with the through hole 518. The hole 511 is connected to the detection roller 501, so that the interior of the chamber 516 is sealed. Under the extrusion and transportation of the piston plate 302, the high-temperature fluid will pass through the interior of the detection roller 501, thereby driving the water impeller 508 to rotate, and then synchronously driving the auger blades 509 fixedly installed on both sides of the axis of the water impeller 508 to rotate. The auger blades 509 can extract and press the interior of the chamber 516, thereby driving the detection roller 501 to move toward the interior of the high-temperature valve 6. When it moves to a certain position, the flange 517 fixedly installed on the limit sleeve 502 will abut and move with the inner wall of the assembly roller 104, so that the docking hole 515 is connected with the assembly hole 518, and at the same time, the L-shaped rod 5 03, the sealing plug 504 is displaced to make one side of the detection roller 501 airtight. Under the continuous squeezing and conveying of the piston plate 302, the internal pressure of the detection roller 501 increases, so that the detection needle 513 can be driven to displace into the docking hole 515, so as to perform a rigidity test on the inside of the high-temperature valve 6. When the detection needle 513 enters the docking hole 515 and continues to displace, it will exert pressure on the flexible pressure-sensitive sheet inside the assembly hole 518, so that the indicator light set on the base 1 will light up, so that it is known that the internal rigidity test of the high-temperature valve 6 does not meet the standard. Otherwise, the indicator light will not light up. The continuous squeezing and conveying of the piston plate 302 and the detection roller 5 01 reaches a certain pressure, the detection needle 513 no longer moves, the sliding plug 2 505 inside the sealing plug 504 moves, so that the sealing inside the detection roller 501 is released, and the fluid can flow to the return pipe 402 through the detection roller 501, so that the water impeller 1 709 rotates, thereby driving the clamp ring 2 204 to move to the initial position, so that the connection between the sealing rod 512 and the through hole 511 is released, and under the action of the tension spring 2 506, the reset spring 2 507, the reset spring 4 514 and the reset spring 3 510, the rigidity detection component 5 is completely reset, so that the rigidity detection of the high-temperature valve 6 to be detected that is moved downward can be carried out.

[0033] The use process of the high-temperature valve internal heating detection device provided by the present invention is as follows: The servo motor 1 701 is set to drive the reciprocating screw 702 to rotate, and the ball screw sleeve 704 designed to mesh with the reciprocating screw 702 drives the clamp ring 1 201 to move, so that the high-temperature valve 6 is sent from the initial position to the detection position. During the displacement process, the hand wheel 603 and the wave plate 710 can be meshed, thereby driving the hand wheel 603 to rotate and put the high-temperature valve 6 in an open state, thereby starting the servo motor 2 315, and the meshing of the small gear 316 and the large gear 317 at the output end of the servo motor 2 315 drives the tank plate 310 to rotate, thereby driving the driving roller 301 to rotate, and then the piston plate 302 designed to mesh with the driving roller moves back and forth. When the piston plate 302 is displaced to the side of the assembly roller 104, the high-temperature liquid can be sent to the high-temperature liquid. The inside of the valve 6 is simulated, thereby simulating the damage of the high-temperature fluid to the sealing packing inside the high-temperature valve 6. At the same time, the cavity on the side of the air duct 308 inside the delivery tank 103 is in a suction state, so that the one-way valve 312 is opened, and the helium stored in the gas storage cavity 106 can be pumped into the delivery tank 103. When the clamp ring 204 moves to the detection position, the sealing rod 512 fixedly installed on the outer wall of the clamp ring 204 will dock with the through hole 511 opened on the outer wall of the assembly roller 104, so that the chamber 516 forms a sealed state. Under the action of the high-temperature fluid, the water impeller 2 508 installed inside the detection roller 501 is driven to rotate, thereby driving the auger blades 509 fixedly installed on both sides of the axis of the water impeller 2 508 to rotate, so that the inside of the chamber 516 can be The detection roller 501 is driven to move to the inside of the high-temperature valve 6 by pumping and pressing, and the flange 517 fixedly installed on the limit sleeve 502 will abut and move with the inner wall of the assembly roller 104, so that the docking hole 515 provided on the limit sleeve 502 is connected with the assembly hole 518 provided on the detection roller 501. At the same time, the sealing plug 504 is driven to move under the action of the L-shaped rod 503, so that one side of the detection roller 501 is sealed. Under the continuous displacement of the piston plate 302, the detection needle 513 installed in the piston sliding manner inside the assembly hole 518 can move toward the inner wall of the high-temperature valve 6, so as to perform rigidity detection. When the internal pressure of the detection roller 501 reaches a certain intensity and the detection needle 513 no longer moves, the sliding plug 505 inside the sealing plug 504 will move, so that The seal inside the detection roller 501 is released, and the high-temperature fluid flows from the detection roller 501 to the return pipe 402, thereby rotating the water impeller 709 inside the fixed roller 705. The teeth 707 set on the disc 706 are meshed with the rack 708 set on the outer wall of the clamping roller 203, so that the clamping ring 204 is displaced to the initial position, thereby releasing the connection between the sealing rod 512 and the through hole 511. The rigid detection component 5 can reset itself under the action of the tension spring 2 506, the reset spring 2 507, the reset spring 4 514 and the reset spring 3 510. Under the continuous displacement of the high-temperature valve 6, the meshing design of the hand wheel 603 and the wave plate 710 makes the high-temperature valve 6 in a closed state, and the piston plate 302 is displaced in the opposite direction.Thus, the sucked helium can be squeezed and transported to the inside of the driving roller 301. The cavity of the delivery tank 103 on one side of the liquid conduit 309 is in a suction state, so that the one-way valve 312 set at the end of the liquid conduit 309 is opened, so that the high-temperature liquid stored in the liquid storage cavity 105 can be pumped into the delivery tank 103 through the liquid conduit 309 to prepare for the next high-temperature valve 6 to be tested. After the helium enters the driving roller 301, it can drive the moving tube 303 to move into the channel connecting the assembly roller 104 and the delivery tank 103. When the moving tube 303 is moved, the moving tube 303 is moved into the channel connecting the assembly roller 104 and the delivery tank 103. When the internal pressure of the moving tube 303 reaches a certain intensity, the slide plate 306 will be displaced to release the seal of the moving tube 303, so that the driving roller 301 is connected with the assembly roller 104, so that the detection gas enters the high-temperature valve 6, and the high-temperature valve 6 is tested for sealing. When the sealing performance of the high-temperature valve 6 meets the standard, the high-temperature valve 6 can be displaced under the continuous pressure of the piston plate 302, otherwise the high-temperature valve 6 cannot be displaced to the initial position, thereby improving the accuracy of the internal heat detection of the high-temperature valve 6.
