A gate valve closing member strength test device

Abstract

This invention belongs to the field of valve strength testing technology and discloses a gate valve closing component strength testing device, including a conveying assembly. Two positioning components are symmetrically installed on the top of the conveying assembly, and a limiting component is installed on the outer wall of the conveying assembly. A testing component is installed on the top of the conveying assembly. In this device, a second motor drives multiple mounting sleeves to rotate via a mounting plate. The rotation of the mounting sleeves causes a pressure block to compress the top of a circular gate plate near the stop arm. During rotation, the pressure block pushes a pressure plate to slide upwards along the mounting sleeve, compressing a force sensor. The force sensor pushes a sliding sleeve to move, compressing the bottom of a fourth spring. Under the elastic force of the fourth spring, the pressure block performs a compression test on the circular gate plate. This design can quickly test multiple gate plates, improving testing efficiency and reducing labor and time costs.

Description

Technical Field

[0001] The invention relates to the field of valve strength testing, and more particularly to a gate valve closing member strength testing device. Background Art

[0002] The closing part of the gate valve is a circular gate disc, which is the key component for the gate valve to open and close. During the production process, in order to better control the production quality of the gate disc, it is necessary to regularly inspect the gate disc and test the strength of the inspected circular gate disc. The gate valve closing part strength test device is a special equipment used to test the strength and sealing performance of the gate disc under specific conditions. This device can simulate the working conditions of the gate valve under actual working conditions and test the compressive strength of the gate disc to ensure that it meets the design and use requirements.

[0003] In the existing technology, such as the document with announcement number CN216208211U, a gate plate testing device is specifically disclosed. In the device in the document, during the test of the gate plate, since only one gate plate can be tested at a time, it is necessary to manually remove the tested gate plate after each test and reinstall a new gate plate to test its pressure resistance. This process is not only time-consuming, but also leads to low overall test efficiency, and frequent manual loading and unloading operations will significantly increase labor costs and time costs.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The circular gate plates are transported by electric rollers on the top of multiple brackets, and the circular gate plates are blocked by two blocking arms, so that most of the circular gate plates are in contact with each other and are kept arranged in a straight line. The second motor drives multiple mounting sleeves to rotate through the mounting plate. When the mounting sleeves rotate, the pressure blocks at the ends thereof squeeze the tops of the circular gate plates close to the blocking arms, and drive the circular gate plates to move along the conveying frame. During the rotation, the pressure blocks push the pressure plates to slide upward along the mounting sleeves, and squeeze the force sensor through the pressure plate. The force sensor pushes the sliding sleeve to move, and squeezes the bottom of the fourth spring through the sliding sleeve, so that the fourth spring is compressed. Under the elastic force of the fourth spring, the circular gate plates are subjected to a compression test through the pressure blocks. This design can quickly test the compression resistance of most gate plates, improve test efficiency, and reduce labor and time costs.

[0020] 2. The second motor drives the two supporting shafts to rotate, which in turn drives the fixed plate to rotate through the supporting shafts, and drives the multiple convex plates to rotate through the fixed plate. When the circular gate plate moves to the top of the multiple electric rollers above the connecting plate, the convex plate squeezes the two external plates. At this time, the external plate drives the connecting plate to move downward, and the connecting plate drives the bracket to move downward through the connecting rod. At this time, both ends of the bracket slide downward along the first sliding rod and squeeze the first spring. At this time, the gate plate is out of contact with the electric roller, and the bottom of the gate plate contacts the top of the conveying frame. The gate plate is fixedly supported by the conveying frame to avoid the bracket moving downward to squeeze the first spring during the test, resulting in the reverse elastic force of the first spring causing the test pressure value to be inaccurate.

[0021] 3. The circular gate plate is limited on both sides by the rollers on the top of the mounting plates on both sides of the conveying frame. The mounting plates slide along the outer wall of the second slide rod according to the size of the circular gate plate and squeeze the second spring, thereby limiting and squeezing the two sides of the circular gate plate, so that the circular gate plate can move stably on the conveying frame.

[0022] 4. After the first motor and the second motor stop, the first motor can be started to drive the second bevel gear to rotate through the driving shaft, and the multiple first bevel gears can be driven to rotate through the second bevel gear. The multiple pressure rods can be driven to rotate through the first bevel gear, so that the threaded sleeve slides along the inner wall of the mounting sleeve, and the length of the fourth spring is shortened or extended, so that the test pressure value can be changed with gate plates of different thicknesses.

[0055] A groove 306 is formed at the end of each of the two blocking arms 301 , and a guide shaft 307 is rotatably connected to the inner wall of each of the two grooves 306 .

[0056] Embodiment 5: This embodiment provides a gate valve closing member strength test device, which further includes the following structure based on the embodiment 4:

[0057] like Figure 9-14 As shown, the bottoms of the two support plates 401 are respectively fixedly connected to the top of the base 101, and the outer wall of the other support plate 401 is fixedly connected to the first base 427, and the bottom of the first base 427 is fixedly connected to the first motor 428, and the output end of the first motor 428 is fixedly connected to the driving shaft 418, and the end of the driving shaft 418 passes through the support plate 401 and is rotatably connected thereto;

[0058] The end of the mounting plate 403 is fixedly connected to the end cover 404, the outer wall of the end cover 404 is fixedly connected to the connecting sleeve 422, the connecting sleeve 422 is sleeved on the driving shaft 418 and is rotatably connected thereto, the connecting sleeve 422 passes through the supporting plate 401 and is rotatably connected thereto, the end of the driving shaft 418 passes through the end cover 404 and is rotatably connected thereto, the outer ends of the pressure rods 406 are fixedly connected to the first bevel gear 417, the inner end of the driving shaft 418 is fixedly connected to the second bevel gear 420, the second bevel gear 420 is respectively meshed with the plurality of first bevel gears 417, the circumferential outer wall of the driving shaft 418 is rotatably connected to the shaft sleeve 419, and the circumferential outer wall of the shaft sleeve 419 is respectively rotatably connected to the plurality of pressure rods 406;

[0059] The outer walls of the two support plates 401 are each provided with a through hole 402, and the end of the external plate 113 passes through the through hole 402 and is slidably connected thereto. The outer walls of the two support plates 401 are rotatably connected to the support shaft 423, and the connecting sleeve 422, the fixed shaft 421 and the circumferential outer walls of the two support shafts 423 are all fixedly connected to the synchronous wheels 424, and the two synchronous wheels 424 on the same side are connected through a synchronous belt transmission. The circumferential outer walls of the two support shafts 423 are each fixedly connected to a fixed disk 425, and the circumferential outer walls of the two fixed disks 425 are each fixedly connected to a plurality of convex plates 426, and the fixed disk 425 is suitable for being driven to rotate so that the convex plate 426 squeezes the corresponding external plate 113 to drive the external plate 113 to move downward.

[0060] The second motor 430 drives the two support shafts 423 to rotate, and drives the fixed plate 425 to rotate through the support shaft 423, and drives the multiple convex plates 426 to rotate through the fixed plate 425. When the circular gate moves to the top of the multiple electric rollers 107 above the connecting plate 111, the convex plate 426 squeezes the two external plates 113. At this time, the external plate 113 drives the connecting plate 111 to move downward, and the connecting plate 111 drives the bracket 106 to move downward through the connecting rod 110. At this time, both ends of the bracket 106 slide downward along the first sliding bar 108 and squeeze the first spring 109. At this time, the gate is out of contact with the electric roller 107, and the bottom of the gate is in contact with the top of the conveying frame 102. The gate is fixedly supported by the conveying frame 102 to avoid the bracket 106 moving downward to squeeze the first spring 109 during the test, resulting in the reverse elastic force of the first spring 109 causing the test pressure value to be inaccurate.

[0061] Working principle: a plurality of circular gate plates are sequentially placed inside the moving hole 104 between the conveying frame 102 and the positioning plate 103, and the circular gate plates are conveyed by the electric rollers 107 on the top of the plurality of brackets 106;

[0062] The roller shafts 202 on the top of the mounting plates 201 on both sides of the conveying frame 102 are used to limit the positions of the two sides of the circular gate plate. The mounting plates 201 slide along the outer wall of the second slide bar 203 according to the size of the circular gate plate and squeeze the second spring 204, thereby limiting and squeezing the two sides of the circular gate plate, so that the circular gate plate can move stably on the conveying frame 102.

[0063] The circular gate plates are blocked by two blocking arms 301 so that most of the circular gate plates are in contact with each other and are arranged in a straight line;

[0064] The first motor 428 and the second motor 430 rotate in the same direction and speed. The second motor 430 drives the mounting plate 403 to rotate through the fixed shaft 421, and drives the plurality of mounting sleeves 405 to rotate through the mounting plate 403. When the mounting sleeve 405 rotates, the pressure block 416 at the end thereof squeezes the top of the circular gate plate close to the blocking arm 301. During the rotation process, the pressure block 416 pushes the pressure plate 414 to slide upward along the mounting sleeve 405, and squeezes the force sensor 413 through the pressure plate 414. The force sensor 413 pushes the sliding sleeve 411 to move, and squeezes the bottom of the fourth spring 410 through the sliding sleeve 411, so that The fourth spring 410 is compressed, the pressing block 416 squeezes the top of the circular gate plate, and drives the circular gate plate to move along the conveying frame 102, and squeezes the guide shafts 307 at the ends of the two blocking arms 301 through the circular gate plate. At this time, the two blocking arms 301 slide along the guide rod 302 and the third sliding rod 304 respectively, and squeeze the third spring 305. At the same time, under the elastic force of the third spring 305, the guide shafts 307 at the ends of the two blocking arms 301 are always in contact with the outer wall of the circular gate plate until the circular gate plate passes through the two blocking arms 301. At this time, the two blocking arms 301 block the next circular gate plate.

[0065] The second motor 430 drives the fixed shaft 421 to rotate, the fixed shaft 421 drives the mounting plate 403 to rotate, and the mounting plate 403 drives the connecting sleeve 422 to rotate when rotating, and drives the synchronous wheel 424 to rotate through the fixed shaft 421 and the connecting sleeve 422 respectively, and drives the two supporting shafts 423 to rotate at the same time, drives the fixed plate 425 to rotate through the supporting shaft 423, and drives the multiple convex plates 426 to rotate through the fixed plate 425. When the circular gate moves to the top of the multiple electric rollers 107 above the connecting plate 111, the convex plate 426 squeezes the two external plates 113. The external plate 113 drives the connecting plate 111 to move downward, and the connecting plate 111 drives the bracket 106 to move downward through the connecting rod 110. At this time, both ends of the bracket 106 slide downward along the first slide bar 108 and squeeze the first spring 109. At this time, the gate plate is separated from the contact with the electric roller 107, and the bottom of the gate plate contacts the top of the conveying frame 102. The gate plate is fixedly supported by the conveying frame 102 to avoid the bracket 106 moving downward to squeeze the first spring 109 during the test, resulting in the reverse elastic force of the first spring 109 causing the pressure value of the test to be inaccurate;

[0066] After the test, under the elastic force of the first spring 109, the multiple brackets 106 drive the motorized rollers 107 to move upward and keep them horizontal with the other motorized rollers 107;

[0067] The fourth spring 410 can squeeze the top of the gate plate under the elastic force, so as to test the compressive strength of the gate plate, and the force sensor 413 can display the highest pressure value generated by the test;

[0068] After the first motor 428 and the second motor 430 stop, the first motor 428 can be controlled to move independently, thereby driving the second bevel gear 420 to rotate through the driving shaft 418, driving the plurality of first bevel gears 417 to rotate through the second bevel gear 420, and driving the plurality of pressure rods 406 to rotate through the first bevel gear 417, so that the threaded sleeve 407 slides along the inner wall of the mounting sleeve 405, shortening or lengthening the length of the fourth spring 410, thereby being able to change the test pressure value with gate plates of different thicknesses.
