Description

Technical Field

[0001] The present application relates to the technical field of sealing detection, and in particular to a sealing detection device for a valve body of a boiler sootblower spring valve. Background Art

[0002] Boiler soot blower is a device used in boilers. It uses the energy of the sound field to repeatedly pull and compress the compacted ash on the walls and bottom of the boiler through alternating density waves at a certain frequency, so that the compacted ash is loosened and falls off due to fatigue, and then falls into the ash hopper and is discharged with the flue gas or under the action of gravity. The spring valve is a device used in the blowing pipe of the boiler soot blower to close the blowing pipe when soot blowing is not needed to prevent the backflow of smoke in the boiler.

[0003] The main purpose of the sealing test of the boiler sootblower spring valve is to ensure that the spring valve can be effectively sealed during operation to prevent gas or liquid leakage. At present, the commonly used method for sealing test of the boiler sootblower spring valve is to immerse the sealing part of the boiler sootblower spring valve in liquid to observe whether bubbles are generated to determine whether there is leakage. This detection operation is relatively troublesome, which makes the detection efficiency of the staff low. Utility Model Content

[0035] When in use, the staff places the boiler sootblower spring valve on the workbench 1 and locks the spring valve. By operating the clamping device 2, the boiler sootblower spring valve is fixed on the workbench 1. The staff fills the water tank 34 with water and starts the water pump 31. The water pump 31 allows the water in the water tank 34 to enter the valve core of the boiler sootblower spring valve from the water inlet hole through the water pipe 33 and the pipe joint 35. The staff puts the humidity sensitive test paper at the valve mouth of the boiler sootblower spring valve. If the color of the humidity sensitive test paper remains unchanged, it proves that the sealing of the valve body of the boiler sootblower spring valve is good. If the color of the humidity sensitive test paper changes, it proves that there is a loophole in the sealing of the valve body of the boiler sootblower spring valve.

[0036] In order to reduce costs, the sealing detection device 3 can be used in multiple places, and when the sealing detection device 3 in this application is not needed, the sealing detection device 3 can be stored. A moving device 4 for moving the position of the sealing detection device 3 is also provided on the side of the sealing detection device 3 close to the ground, and the water supply pipe 33 is detachably connected to the pipe joint 35.

[0037] Reference Figure 1 and Figure 2 The mobile device 4 includes a mobile trolley 41. The mobile trolley 41 includes a first bottom plate (not shown in the figure), a vertical plate 411 fixedly connected to one side of the first bottom plate, a second bottom plate 412 fixedly connected to the side of the vertical plate 411 away from the first bottom plate, a plurality of support legs 413 fixedly connected to the side of the second bottom plate 412 close to the ground, and a universal wheel 414 installed on the side of each support leg 413 close to the ground. Among them, the vertical plate 411 is perpendicular to the first bottom plate and the second bottom plate 412, and the first bottom plate and the second bottom plate 412 are parallel to each other, that is, the first bottom plate, the vertical plate 411 and the second bottom plate 412 are in a stepped shape, the first bottom plate is located on the side of the second bottom plate 412 close to the ground, the water storage tank 34 is placed on the first bottom plate, and the water pump 31 is placed on the second bottom plate 412.

[0038] When in use, the staff pushes the mobile cart 41 to an external water source, fills the water tank 34 with water, pushes the mobile cart 41 to the vicinity of the workbench 1, installs the water pipe 33 to the pipe joint 35, starts the water pump 31, and performs a sealing test on the valve body of the boiler sootblower spring valve.

[0039] Reference Figure 2In order to reduce the possibility of the water tank 34 or the water pump 31 being offset or skewed during the movement or operation, the mobile device 4 further includes a protective assembly 42, which includes a first enclosure 421 fixedly connected to the side of the first bottom plate away from the ground and a second enclosure 422 fixedly connected to the side of the second bottom plate 412 away from the ground. Three first enclosures 421 are arranged along the side of the first bottom plate, and the adjacent two sides of the three first enclosures 421 are connected to each other. Three second enclosures 422 are arranged along the side of the second bottom plate 412, and the adjacent two sides of the three second enclosures 422 are connected to each other. The two first enclosures 421 arranged opposite to each other and the two second enclosures 422 arranged opposite to each other are respectively located in the same plane, and the side of the first enclosure 421 away from the first bottom plate and the side of the second enclosure 422 away from the second bottom plate 412 are located in the same horizontal plane.

[0040] During use, when the staff pushes the mobile cart 41 to move, if the mobile cart 41 is violently bumped or hit, the water tank 34 hits the first enclosure 421 and is blocked by the first enclosure 421. The position of the water tank 34 will not move too much. Similarly, the position of the water pump 31 will not be too offset due to being blocked by the second enclosure 422.

[0041] In order to facilitate the staff to push the moving cart 41 , a push rod 43 is provided on the side of the second enclosure 422 away from the water pump 31 . When in use, the staff can push the moving cart 41 by holding the push rod 43 .

[0042] Reference Figure 1 In order to facilitate the staff to transport or store the mobile device 4 and the water tank 34 and the water pump 31 installed in the mobile device 4, the mobile vehicle 41 also includes an installation cover 44 installed on the side of the first enclosure 421 and the second enclosure 422 away from the ground.

[0043] The workbench 1 comprises a fixed plate 11 and a plurality of legs 12 mounted on a side of the fixed plate 11 close to the ground, and the water inlet is located at the center of the fixed plate 11 .

[0044] In order to facilitate the staff to move and store the workbench 1, the leg 12 is hinged on the fixed plate 11, and the leg 12 includes two connecting plates 121 fixedly connected to the fixed plate 11 and arranged opposite to each other on the side close to the ground, a sleeve 122 rotatably connected between the two connecting plates 121, a support column 123 slidably connected in the sleeve 122, a first fixing bolt 124, and a second fixing bolt 125 threadedly connected to the connecting plate 121. Among them, a first threaded hole for screwing the first fixing bolt 124 is provided on the side wall of the sleeve 122 close to the end of the sleeve 122 away from the fixed plate 11, and a second threaded hole for screwing the first fixing bolt 124 is provided on the side wall of the support column 123 close to the end of the fixed plate 11; a third threaded hole for screwing the second fixing bolt 125 is provided on the side wall of the sleeve 122 close to the connecting plate 121, and a fourth threaded hole and a fifth threaded hole for screwing the second fixing bolt 125 are provided on the connecting plate 121.

[0045] During use, when the staff needs to move the transport workbench 1, the staff unscrews the first fixing bolt 124 from the first threaded hole and the second threaded hole, slides the support column 123 into the sleeve 122, and then unscrews the second fixing bolt 125 from the third threaded hole and the fourth threaded hole, and rotates the sleeve 122 to a horizontal position. At this time, the third threaded hole and the fifth threaded hole coincide, and the second fixing bolt 125 is screwed into the third threaded hole and the fifth threaded hole, so that the sleeve 122 and the fixed plate 11 are in a parallel position, thereby reducing the space occupied by the workbench 1 in the vertical direction.

[0046] Reference Figure 1 and Figure 4 The clamping device 2 includes a mounting block 21 mounted on the side of the fixed plate 11 away from the ground, a screw rod 22 fixedly connected to the mounting block 21 on the side away from the fixed plate 11, an adjusting nut 23 threadedly connected to the screw rod 22, and an abutment block 24 slidably connected to the side of the mounting block 21 away from the fixed plate 11, and a slide groove 25 for the screw rod 22 to move is opened on the abutment block 24 along the length direction of the abutment block 24.

[0047] When in use, the staff puts the flange of the boiler sootblower spring valve against the fixed plate 11 so that the water inlet hole is aligned with the valve body of the spring valve. The staff rotates the adjusting nut 23 and moves the abutment block 24 so that the abutment block 24 abuts against the flange of the spring valve close to the fixed plate 11. The adjusting nut 23 is rotated again so that under the action of the adjusting nut 23, the abutment block 24 presses the flange tightly, thereby fixing the spring valve on the fixed plate 11.

[0048] Reference Figure 4In order to increase the friction between the abutting block 24 and the flange, so that the abutting block 24 can better fix the flange, a buffer pad 26 is provided on the side of the abutting block 24 close to the fixing plate 11, and the buffer pad 26 is made of rubber.

[0049] In order to make the boiler sootblower spring valve more firmly fixed on the fixed disk 11, a plurality of clamping devices 2 are arranged at circumferential intervals around the center of the fixed disk 11, so that the boiler sootblower spring valve is subjected to the force of the abutment block 24 in different directions, thereby making the boiler sootblower spring valve more firmly fixed.

[0050] Reference Figure 1 In order to facilitate the staff to test the pressure bearing capacity of the spring valve while testing the sealing performance of the boiler sootblower spring valve body, a pressure measuring tube 5 for testing the pressure bearing capacity of the spring valve is also provided on the pipe joint 35, and a pressure indicator 6 is provided at the other end of the pressure measuring tube 5.

[0051] When in use, the staff starts the water pump 31, and when testing the sealing performance of the boiler sootblower spring valve body, observes the value change of the pressure indicator 6, and observes whether the outer wall of the spring valve body is deformed under different pressures, thereby obtaining the pressure bearing capacity of the boiler sootblower spring valve body.

[0052] The implementation principle of a boiler sootblower spring valve body sealing detection device according to an embodiment of the present application is as follows: when in use, the staff holds the push rod 43 to push the mobile cart 41, pushes the mobile cart 41 to the side of the external water source, fills the water tank 34 with water, pushes the mobile cart 41 to the vicinity of the workbench 1, installs the water pipe 33 to the pipe joint 35, operates the clamping device 2 to fix the spring valve on the workbench 1, starts the water pump 31, and the water in the water tank 34 reaches the spring valve body through the water pipe 33 and the water inlet hole. At this time, the staff places a moisture-sensitive test paper at the valve mouth of the spring valve to observe whether the moisture-sensitive test paper changes color. If the moisture-sensitive test paper changes color, it proves that there is a problem with the sealing of the boiler sootblower spring valve; if the moisture-sensitive test paper does not change color, continue to pressurize, regularly observe the value changes of the pressure indicator 6 and whether the outer wall of the spring valve body is deformed, and test the pressure-bearing capacity of the boiler sootblower spring valve body.

[0053] When the staff needs to store or transport the boiler sootblower spring valve body sealing detection equipment in the present application, the staff removes the water pipe 33 from the pipe joint 35, stores it in the second enclosure 422, installs the installation cover 44 on the mobile cart 41, and then rotates the legs 12 of the workbench 1 around its hinge axis to save storage space and facilitate the staff to store the workbench 1.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
