Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of hole device, especially a hole device is used in pipeline in clean environment under pressure. BACKGROUND

[0002] Semiconductor industry process cooling system provides cooling for chip, panel and other process equipment, and the production line changes frequently, so it is necessary to additionally open a hole under pressure in the process cooling water system. Generally, the process equipment does not stop running, and the process cooling system has high requirements for ph value, water quality, water temperature, water pressure fluctuation and solid particles in the pipeline. The conventional hole under pressure adopts a barrel cutter, and the barrel cutter is currently limited by the size and cutting method of the barrel cutter, which produces the smallest iron filings of 2mm, causing the precision machine to be blocked and causing the equipment to be down, affecting normal production. The existing water cutter hole under pressure technical scheme cannot avoid pressure fluctuation during the hole under pressure, and there is a risk of equipment downtime. At the same time, the cutting pomegranate sand particle size of the existing technology is about 20um, which will mostly enter the pipeline, and the pomegranate sand attached to the inner wall of the stainless steel pipeline will cause rust, causing the process cooling system to replace the bag filter, resulting in large consumption of filtering materials. SUMMARY

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This utility model provides a device for pressurized pipe tapping in clean environments, which solves the problems mentioned in the background art: conventional pressurized tapping uses a barrel cutter, which is currently limited by the size and cutting method of the barrel cutter, producing a minimum of 2mm iron filings, which can cause blockage of precision machines, leading to equipment downtime and affecting normal production. Furthermore, existing waterjet pressurized tapping technology cannot avoid pressure fluctuations during the tapping process, posing a risk of equipment downtime. Additionally, the garnet abrasive used in existing technologies has a particle size of approximately 20µm, most of which enters the pipe, adhering to the inner wall of the stainless steel pipe and causing rust, necessitating the replacement of bag filters in the process cooling system and resulting in significant waste of filter consumables.

[0013] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0014] A device for pressurized pipe opening in a clean environment includes: a stabilizing unit 1, an opening unit 2, and a recycling unit 3. The opening unit 2 is fixed inside the stabilizing unit 1. Two recycling units 3 are configured, and the two recycling units 3 are used in conjunction with the stabilizing unit 1 and the opening unit 2.

[0015] The stabilizing unit 1 includes: a reinforcing arc plate 1-1, an extension tube 1-2, a ball valve 1-3, and a sealing cover 1-4. The upper end of the reinforcing arc plate 1-1 is fixed with the extension tube 1-2, the upper end of the extension tube 1-2 is fixed with the ball valve 1-3, and the upper end of the ball valve 1-3 is detachably and sealingly fixed with the sealing cover 1-4.

[0016] The opening unit 2 includes: a pressure-stabilized air supply pipe 2-1, a water grinding fluid inlet pipe 2-2, a water grinding fluid return pipe 2-3, an electrically controlled rotary table 2-4, and a water jet 2-5. The pressure-stabilized air supply pipe 2-1 is sealed and fixedly passes through the sealing cover 1-4. The water grinding fluid inlet pipe 2-2 is sealed and fixedly passes through the sealing cover 1-4. The water grinding fluid return pipe 2-3 is sealed and fixedly passes through the sealing cover 1-4. The electrically controlled rotary table 2-4 is detachably and sealed and fixedly installed inside the extension pipe 1-2. The rotation platform of the electrically controlled rotary table 2-4 is fixedly connected to the water jet 2-5. The water grinding fluid inlet pipe 2-2 is fixedly connected to the water jet 2-5. The water grinding fluid return pipe 2-3 passes through the electrically controlled rotary table 2-4.

[0017] The two recycling units 3 include: a protective rubber block 3-1 and a conductive coil 3-2, wherein the conductive coil 3-2 is disposed inside the protective rubber block 3-1.

[0018] The electrically controlled rotary table 2-4 is existing technology and has been purchased externally. This device is also connected to a pressure-stabilized gas source controller, which is also existing technology and has been purchased externally.

[0019] The working principle of this utility model is as follows:

[0020] During use, the reinforcing arc plate 1-1 is welded to the pipe where the hole needs to be drilled. This prevents cracking at the opening location caused by sudden changes in pipe stress. Then, the protective rubber block 3-1 is placed on the pipe and rests against the reinforcing arc plate 1-1. The conductive coil 3-2 is energized to generate electromagnetic induction. The pressure-stabilized air source controller is then fixedly connected to the pressure-stabilized air source flow pipe 2-1. Based on the pressure in the pipe, a pressure-stabilized air source of equal pressure is introduced to ensure that the pressure fluctuates within a small range during the drilling process, avoiding the risk of equipment downtime. Then, the water jet 2-5 is activated, and the water-grinding fluid is introduced into the water-grinding fluid... The water enters through pipe 2-2 and is then sprayed out through water jet 2-5. The electrically controlled rotary table 2-4 is powered to drive the water jet 2-5 to rotate and perform the opening operation on the pipe. This device is connected to an external power source. During operation, the waste liquid is sucked out through the water grinding fluid return pipe 2-3. After the opening is completed, the conductive coil 3-2 can adsorb the abrasive of the water grinding fluid that enters through the gap onto the inner wall of the pipe. This can solve the problem of abrasive entering the inner wall of the pipe causing rust and causing large consumption of filter consumables. After the device is disassembled, the inner wall of the pipe is cleaned and then the protective rubber block 3-1 is removed.

[0021] To ensure that the electromagnetic induction generated by the conductive coil 3-2 can adsorb the water grinding fluid, the water grinding fluid is prepared as follows: a mixture of iron-based or nickel-based materials and alumina.

[0022] The function of ball valve 1-3 is to provide a downward channel for water jet 2-5 to facilitate the installation of water jet and the removal of water jet 2-5 after construction. It can also prevent leakage caused by sudden changes in the working medium pressure in the pipeline during operation, and the closing of ball valve 1-3 after construction can prevent the normal flow of the working medium in the pipeline and avoid leakage.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
