Description

Technical Field

[0001] This utility model relates to the field of safety valve calibration technology, specifically to an external calibration base for safety valves. Background Technology

[0002] With the further development of my country's industrialization, safety valves are widely used in industries such as boilers, chemicals, and pressure vessels. According to TSG ZF001-2006 "Safety Valve Safety Technical Supervision Regulations" and related safety technical supervision regulations for boilers and pressure vessels, safety valves generally need to be calibrated once a year.

[0003] Chinese Patent No. CN201920291269.8 discloses a safety valve calibration bench, including a base with a mounting groove. A piston ring is connected to the mounting groove in a piston-like manner. An air supply pipe is fixed to the base inside the piston ring. A sealing membrane is sleeved on the outer wall of the portion of the air supply pipe above the bottom surface of the mounting groove. The sealing membrane forms a sealed chamber with the piston ring through the inner wall of the base. The expansion and contraction of the sealing membrane is controlled by the up and down sliding of the piston ring. Several fixing plates are provided on the outer side of the piston ring and slidably connected to the base by fixing plate springs. When the safety valve is located in the mounting groove, the sealing membrane is tightly attached to the inner wall of the safety valve, and the fixing plates move to the upper side wing of the safety valve for limiting.

[0004] During use, this utility model is inconvenient for calibrating safety valves of different sizes because the size of the mounting slot is relatively uniform. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 In this embodiment of the utility model, the external calibration base of the safety valve includes a calibration disc assembly 20, a multi-hole flange base 5, and a support structure 16. A moving mechanism 18 is installed at the bottom of the support structure 16. The multi-hole flange base 5 is installed on the upper side of the support structure 16. The calibration disc assembly 20 is installed on the upper side of the multi-hole flange base 5. A threaded connection interface 3 is installed at the middle of the bottom of the multi-hole flange base 5. A control groove 6 is installed at the upper end of the multi-hole flange base 5. Several multi-specification flange holes 7 are provided at the upper end of the multi-hole flange base 5. A slot 8 is provided on one side of the multi-hole flange base 5. The slot 8 is connected to the air source inlet interface 4. The calibration disc assembly 20 is composed of a first calibration disc 9, a second calibration disc 10, a third calibration disc 11, a fourth calibration disc 12, a fifth calibration disc 13, and a sixth calibration disc 14. The safety valve 1 is installed on the upper end of the multi-hole flange base 5 by fixing bolts 2.

[0027] Furthermore, the control slot 6 is configured as a stepped groove, which facilitates the calibration of the calibration disk assembly 20 and makes it easier to quickly assemble the calibration disk assembly 20 that is needed.

[0028] Furthermore, the first verification disk 9, the second verification disk 10, the third verification disk 11, and the fourth verification disk 12 are stacked on the support structure 16, and the unused first verification disk 9, the second verification disk 10, the third verification disk 11, and the fourth verification disk 12 are stacked inside the support structure 16, which facilitates the storage of the first verification disk 9, the second verification disk 10, the third verification disk 11, and the fourth verification disk 12.

[0029] Furthermore, a control base 15 is placed below each of the first verification disk 9, the second verification disk 10, the third verification disk 11, and the fourth verification disk 12. The control base 15 is located at the bottom of the second verification disk 10, the third verification disk 11, the fourth verification disk 12, and the support structure 16. The setting of the control base 15 can, on the one hand, separate the first verification disk 9, the second verification disk 10, the third verification disk 11, and the fourth verification disk 12, and on the other hand, prevent the first verification disk 9, the second verification disk 10, the third verification disk 11, and the fourth verification disk 12 from rubbing against each other and causing wear.

[0030] Furthermore, a door 22 is rotatably installed on the outside of the support structure 16, and a handle 21 is installed on the upper side of the door 22. The door 22 is designed to close the support structure 16, which facilitates the protection of the inside of the support structure 16. The handle 21 is designed to make it easy for staff to hold, thus making it easy to open and close the door 22.

[0031] Furthermore, a storage box 23 is installed at one end of the outer side of the support structure 16. The fifth verification disk 13 and the sixth verification disk 14 are placed inside the storage box 23. The fifth verification disk 13 and the sixth verification disk 14 are relatively small in size, and the storage box 23 is convenient for placing the relatively small fifth verification disk 13 and the sixth verification disk 14 inside the storage box 23.

[0032] Furthermore, the moving mechanism 18 consists of a rubber wheel 17 and a fixing clamp 19. The rubber wheel 17 is installed around the bottom of the support structure 16, and the fixing clamp 19 is rotatably installed on one side of the rubber wheel 17. The rubber wheel 17 facilitates the movement of the support structure 16 during use, and the fixing clamp 19 facilitates the fixing of the rubber wheel 17.

Install the air source inlet interface 4 inside the groove 8 and connect it to the safety valve 1. Introduce outside air into the safety valve 1 through the air source inlet interface 4 to verify the safety valve 1. Therefore, after maintenance, the safety valve 1 can be fixed on the multi-hole flange base 5 with fixing bolts, and the safety valve 1 can be verified on site.
