Description

Technical Field

[0001] This utility model relates to the field of connection technology, and in particular to a tool for quickly replacing sealing gaskets. Background Technology

[0002] In various types of media pipelines, including water pipes, gas pipes, oxygen pipes, nitrogen pipes, and steam pipes, there are control valves and connecting flanges. During daily use, prolonged use can cause gaskets to age, leading to leaks of air, water, or steam, necessitating quick and safe replacement of the gaskets.

[0003] In the current process of replacing gaskets on flanges in general locations, we use a pry bar to pry open the gap for replacement. However, this poses a safety hazard of the pry bar slipping and causing injury during the operation. When replacing gaskets on flanges in special locations, we need to weld a support point at the pipeline and use a jack to open the gap for replacement. This process is labor-intensive, unsafe, requires cumbersome tools, and takes a long time. When working on some important pipeline locations, it is inevitable that it will affect production. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a tool for quickly replacing gaskets. This tool can solve the problem of replacing flange gaskets by prying open the gap with a pry bar, which poses a safety hazard of the pry bar slipping and causing injury during the operation. In some special parts of the flange, when replacing gaskets, we need to weld a support point at the pipeline and use a jack to open the gap for replacement. This process is labor-intensive, unsafe, requires cumbersome tools, and takes a long time. It is also inevitable that the operation will affect production when working on some important pipeline parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tool for quickly replacing sealing gaskets, comprising a fixed base plate, an adjusting screw, a fixing pin, and two T-shaped hooks. The upper surface of the fixed base plate has two slider grooves, and the outer walls of the two T-shaped hooks are slidably connected to the interior of their respective slider grooves. The upper surface of the fixed base plate has an adjusting screw groove.

[0006] The outer wall of the adjusting screw is connected to the internal thread of the adjusting screw groove, and the lower outer wall of the two T-shaped hooks is provided with a fixing pin groove.

[0007] Preferably, the outer wall of the fixing pin is slidably connected to the inside of the two fixing pin grooves;

[0008] The end of the adjusting screw furthest from the fixed base plate is fixedly connected with a screw head.

[0009] Preferably, one end of the fixing pin is fixedly connected to a fixing bolt head;

[0010] The outer wall of the end of the fixing pin away from the head of the fixing bolt is provided with external threads.

[0011] Preferably, the end of the adjusting screw near the fixed base plate extends threadedly to the lower end of the fixed base plate.

[0012] Preferably, the end of the fixing pin furthest from the fixing bolt head is externally threaded with a fixing nut;

[0013] The adjusting screw is fixedly connected to a top block at the end near the fixed pin.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This quick-change gasket tool uses an external clamp to fix a base plate to the equipment where the gasket needs to be replaced. Then, according to the position and size of the gasket, the screw head is turned to rotate, which in turn rotates the adjusting screw and adjusts the height of the adjusting screw. At the same time, the position is locked using a fixing pin. Then, the size of the gap between the adjusting screw and the flange is adjusted to determine whether the operation requirements are met. This allows for the replacement of various flange gaskets in the shortest time, in a simple, safe, and efficient manner. It not only saves time and labor but also minimizes the time lost due to pipeline gasket replacement operations. Attached Figure Description

[0026] Please see Figure 1-4 This utility model provides a technical solution: a tool for quickly replacing sealing gaskets, including a fixed base plate 1, an adjusting screw 3, a fixing pin 7, and two T-shaped hooks 2. Two sliding grooves 4 are formed on the upper surface of the fixed base plate 1. The outer walls of the two T-shaped hooks 2 are slidably connected to the interior of their respective sliding grooves 4. An adjusting screw groove 10 is formed on the upper surface of the fixed base plate 1. The outer wall of the adjusting screw 3 is threadedly connected to the interior of the adjusting screw groove 10. Fixing pin grooves 11 are formed on the lower outer walls of both T-shaped hooks 2. The outer walls of the fixing pins 7 are slidably connected to the interior of the two fixing pin grooves 11. A screw head 9 is fixedly connected to the end of the adjusting screw 3 away from the fixed base plate 1. A fixing bolt head 8 is fixedly connected to one end of the fixing pin 7. An external thread is provided on the outer wall of the end of the fixing pin 7 away from the fixing bolt head 8. The thread of the adjusting screw 3 near the fixed base plate 1 extends to the lower outer side of the fixed base plate 1. A fixing nut 5 is threadedly connected to the external side of the fixing pin 7 away from the fixing bolt head 8. A top block 6 is fixedly connected to the end of the adjusting screw 3 near the fixing pin 7.

[0027] Furthermore, when using this device, firstly, fix the base plate 1 to the equipment whose gasket is to be replaced using an external clamp. Then, according to the position and size of the gasket, turn the screw head 9 to rotate, thereby rotating the adjusting screw 3 and adjusting the height of the adjusting screw 3. At the same time, use the fixing pin 7 to lock the position. Then, by adjusting the size of the flange gap against the adjusting screw 3, it is determined whether the operation requirements are met. After the operation is completed, turn the screw head 9 to rotate, causing the adjusting screw 3 to retract and the flange gap to return to its original position. This indicates that the tool has met the design requirements.

[0028] By fixing the base plate 1 to the equipment whose gasket is to be replaced using external clamps, and then adjusting the height of the adjusting screw 3 by turning the screw head 9 according to the position and size of the gasket, while simultaneously locking the position using the fixing pin 7, the gap between the adjusting screw 3 and the flange is determined by adjusting the gap. This allows for the replacement of various flange gaskets in a simple, safe, and efficient manner in the shortest possible time. It not only saves time and labor but also minimizes the time lost due to pipeline gasket replacement work.

[0029] Structural Description: Fixed Base Plate 1: As the foundation of the entire tool, the fixed base plate 1 is fixed to the equipment to be replaced with the gasket by an external clamp, thus providing a stable support platform and ensuring that the tool will not move or tilt during operation;

[0030] Adjusting screw 3: The adjusting screw 3 is vertically installed on the fixed base plate 1 and is rotated and height adjusted by the screw head 9. By rotating the adjusting screw 3, its height can be precisely adjusted, thereby checking the flange gap and judging whether the installation position of the sealing gasket is accurate. At the same time, the adjusting screw 3 is also the main component in the tool used to apply pressure or tension.

[0031] Fixed pin 7: The fixed pin 7 passes through the fixed pin groove 11 on the adjusting screw 3 to lock the adjusting screw 3 in a specific position, ensuring that it can remain stable after the height of the adjusting screw 3 is adjusted, and preventing displacement during operation.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
