Description

Technical Field

[0001] The utility model belongs to the technical field of nitrogen cylinder disassembly tools, and mainly relates to a tooling for disassembling and assembling parts of a nitrogen cylinder that uses hydraulic pressure for disassembly. Background Technique

[0002] As a colorless, odorless, non-toxic inert gas, nitrogen is widely used in fields such as metallurgy, chemical industry, electronics, and weapon equipment research and development. During production and use, nitrogen needs to be stored. Currently, the storage of nitrogen mainly adopts the method of compressing gas, and nitrogen is compressed to a certain pressure and then stored in high-pressure cylinders. When repairing a nitrogen cylinder, it is necessary to disassemble and assemble the nitrogen cylinder and the support body of the product, which requires disassembling the parts of the nitrogen cylinder. However, it is found during the disassembly process that the exhaust pipe of the nitrogen cylinder and the support body are tightly assembled together by mechanical force. Since both of them are made of stainless steel and the fitting clearance is extremely small, after long-term use, a phenomenon similar to "cold welding" is likely to occur, causing the exhaust pipe and the support body to stick together. Moreover, the thickness of the shearing part of the exhaust nozzle of the gas cylinder exhaust pipe is only 0.4 mm. If conventional disassembly methods such as mechanical force or air pressure are used to disassemble the parts of the nitrogen cylinder, it will not only cause damage to the exhaust pipe of the nitrogen cylinder but may even lead to the fracture of the root of the exhaust pipe of the nitrogen cylinder, and the 40 MPa high-pressure nitrogen in the nitrogen cylinder will rush out rapidly, causing personal safety accidents and making it impossible to safely and completely disassemble the parts of the nitrogen cylinder.

[0005] The airtight component includes an airtight threaded joint arranged at the top of the support body and plugs and stoppers arranged at the front and rear ends of the lower part of the support body; the airtight tube inside the airtight threaded joint penetrates through the support body, and the end of the airtight tube extending into the support body is arranged above the exhaust nozzle.

[0006] The plug is connected to the support body by screw A, and a sealing ring is also installed between the two, which can achieve end face sealing.

[0007] The plug is connected to the support body through a thread, and a sealing ring is installed between the two to achieve radial sealing.

[0008] The exhaust pipe of the nitrogen cylinder is assembled with the support body by mechanical force pressing.

[0017] The present utility model will be described in conjunction with the accompanying drawings.

[0018] As Figure 1 、 Figure 2 shown, a tooling for disassembling a nitrogen cylinder assembly using liquid pressure includes a nitrogen cylinder 1; the nitrogen cylinder 1 is horizontally arranged, and a vertically arranged support body 2 is provided on one side of its cylinder body; an exhaust nozzle 3 extending out of the cylinder body is provided inside the nitrogen cylinder 1; the support body 2 is of a T-shaped structure, and at the part where one side of the support body 2 contacts the cylinder body of the nitrogen cylinder 1, the exhaust nozzle 3 on the nitrogen cylinder 1 extends into the support body 2; a hoop 4 for fixing the cylinder body is further provided on the outer side of the cylinder body of the nitrogen cylinder 1; an airtight component is further provided on the support body 2; both the nitrogen cylinder 1 and the support body 2 are made of stainless steel.

[0019] The airtight component includes an airtight threaded joint 5 arranged at the top of the support body 2, and plug covers 6 and plugs 7 arranged at the front and rear ends of the lower part of the support body 2; the airtight tube 8 inside the airtight threaded joint 5 penetrates through the support body 2, and the end of the airtight tube 8 extending into the support body 2 is arranged above the exhaust nozzle 3; the plug cover 6 is connected to the support body 2 by screw A9, and a sealing ring is also installed between the two to achieve end face sealing; the plug 7 is connected to the support body 2 by threads, and a sealing ring is also installed between the two to achieve radial sealing; the exhaust pipe 3 of the nitrogen cylinder 1 and the support body 2 are assembled together by mechanical force pressing; the upper and lower surfaces of the hoop belt 4 are respectively connected to the side surface and the bottom surface of the support body by the set screws B10; here, to prevent the nitrogen cylinder 1 from colliding with other devices at high speed when it comes out, a hoop belt 4 is installed between the nitrogen cylinder 1 and the support body 2 for protection to ensure the safety of the nitrogen cylinder 1; the airtight threaded joint 5 is connected to the manual pump of the external test device by internal and external threads, and a copper gasket is installed between the connecting end faces of the two for sealing; here, the manual pump provides hydraulic pressure (about 40MPa - 50MPa) to the support body 2, which can make the exhaust nozzle 3 of the nitrogen cylinder 1 and the support body 2 slowly separate. According to Pascal's principle, based on the incompressibility and fluidity of the liquid, the manual pump is used to control the flow rate and pressure of the liquid medium, convert the liquid pressure into mechanical energy, and then achieve the transmission of pressure.

[0020] When the present utility model is in use, it can cooperate with the manual hydraulic pump of the test device to disassemble the nitrogen cylinder assembly. First, connect the nitrogen cylinder assembly to be disassembled to the special disassembly tooling, seal the support body 2 with the plug cover 6, and then screw the airtight threaded joint 5 into the top of the support body 2; connect the airtight threaded joint 5 to the manual pump of the external test device, and then fix the hoop belt 4 to the side surface and the bottom surface of the support body 1 respectively by screw B10, and fix the nitrogen cylinder 1 at the same time; finally, use the manual pump to generate hydraulic pressure and apply it to the connection part between the nitrogen cylinder 1 and the support body 2. When the hydraulic pressure reaches a certain value, it can overcome the fastening force at the connection part between the pipeline of the nitrogen cylinder 1 and the support body 2. This hydraulic pressure gradually pushes open the pipeline of the nitrogen cylinder 1 without directly acting on the cylinder body of the nitrogen cylinder 1, avoiding damage to the root of the air pipe of the nitrogen cylinder 1, so as to achieve the efficient and safe separation of the nitrogen cylinder 1 assembly and the support body 2.
