Description

Technical Field

[0001] This utility model relates to the field of waterjet cutting technology, specifically to small-diameter ultra-high pressure pipes. Background Technology

[0002] In waterjet cutting applications, high-pressure pipelines and high-pressure connectors are usually used for connection. However, the hoses used for waterjet cutting generally need to deliver pressures of around 100 MPa, and there are high difficulties in producing small-diameter, thick steel wires.

[0003] Furthermore, the poor installation stability and sealing performance of traditional high-pressure pipelines may lead to leaks or detachment of the pipelines under high pressure. Insufficient pressure-bearing capacity of the hoses can cause pipe or hose rupture and damage, thereby shortening the life of the equipment and increasing maintenance and replacement costs. At the same time, insufficient protection of the inner wall of the hose can cause abrasive particles in the medium to damage the inner wall of the pipe during waterjet cutting, thereby reducing cutting quality and efficiency and increasing production and time costs. In view of this, we propose small-diameter ultra-high-pressure pipes to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to provide a small-diameter ultra-high pressure pipe to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a small-diameter ultra-high pressure hose, comprising a hose body, a high-pressure nozzle, a mounting bracket, a seal, positioning bolts, a connector, a stabilizing connector, a buffer spring, and an inner lining of the hose. Multiple positioning bolts are evenly spaced on one side of the mounting bracket. The mounting bracket is detachably connected to the connector via the positioning bolts. A high-pressure nozzle is threaded onto one side of the connector. The surface of the mounting bracket away from the connector has a threaded structure, and a seal is threaded onto the mounting bracket.

[0006] Preferably, the connector is provided with a stabilizing connector inside the mounting bracket, a buffer spring is sleeved between the stabilizing connector and the connector, and a rubber tube body is detachably connected between the stabilizing connector and the sealing element.

[0007] Preferably, the hose body is made of rubber material, and an inner hose liner is bonded to the hose body, with metal wires wound between the hose body and the inner hose liner.

[0008] Preferably, the inner lining of the hose is made of ultra-high molecular weight polyethylene material, and the metal wire is 0.6Ht steel wire.

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

[0010] 1. The mounting bracket is movably connected to the connector via positioning bolts, ensuring the safe operation and sealing performance of the pipeline under high pressure. The threaded structure on the surface of the mounting bracket is threadedly connected to the sealing element, and the hose body is detachably connected to the stabilizing connector and the sealing element, improving the connection between the hose body and the high-pressure nozzle, enabling the high-pressure nozzle to effectively spray high-pressure liquid. A buffer spring is sleeved between the stabilizing connector and the connector, which further enhances the durability of the pipeline and reduces stress and vibration caused by pressure changes, ensuring reliable performance and long-term stability of small-diameter ultra-high-pressure pipes in complex industrial applications.

[0011] 2. A metal wire is wound between the hose body and the inner lining of the hose. The metal wire is made of 0.6Ht steel wire, which enables the hose body to withstand pressure of more than 300Mpa. Combined with the inner lining of the hose made of ultra-high molecular weight polyethylene, it can meet the high pressure requirements and reduce the damage of abrasive in the medium to the inner wall of the hose during waterjet cutting.
