Description

Technical Field

[0001] The utility model belongs to the field of pipe fittings and relates to a pipe fitting, in particular to a novel hydraulic pipe fitting. Background Art

[0002] Hydraulic pipe is a pipe used by hydraulic cylinders to transfer oil. However, hydraulic pipe fittings are subject to high pressure in hydraulic oil circuits. Hydraulic pipes have complex shapes. Some of them have right-angle hydraulic pipe joints that are inconvenient to connect at corners. Right-angle pipe joints are prone to bending at the corner connection positions and cannot withstand excessive pressure. Ordinary hydraulic pipes only rely on material strength to ensure impact resistance, which makes the impact resistance of hydraulic pipes weak. After being subjected to impact for a long time, they are easily damaged, resulting in water leakage. At the same time, the impact of oil on the corners of right-angle hydraulic pipes will produce loud noises. Summary of the invention

[0003] The purpose of the utility model is to provide a new type of hydraulic pipe fitting to solve the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A new type of hydraulic pipe fitting, comprising a pipe fitting body arranged in a right-angle structure, characterized in that a plurality of slow-flow ribs for improving the impact strength are arranged on the inner circumferential wall of the pipe fitting body, and the plurality of slow-flow ribs are arranged in a spiral structure and distributed on the inner circumferential wall of the pipe fitting body in sequence;

[0005] A rubber strip for improving the impact resistance and having a mute effect is arranged between two adjacent slow-flow ribs, and the rubber strip is embedded and installed on the inner peripheral wall of the pipe body;

[0006] Both ends of the pipe body are provided with connection flanges for improving the connection strength;

[0007] The plurality of flow-slowing ribs are all arranged in a sheet-like structure and are arranged as an integrally formed structure with the inner peripheral wall of the pipe body.

[0008] In the above-mentioned novel hydraulic pipe fitting, the surfaces of several rubber strips are plated with an anti-corrosion coating for preventing oil corrosion, and the rubber strips are located between two adjacent slow-flow ribs.

[0009] In the above-mentioned new type of hydraulic pipe fitting, the rubber strip, flow-slowing ribs and the inner wall structure of the pipe fitting body cooperate to form a buffer cavity for improving impact resistance. The buffer cavity structure can effectively slow down the flow of oil with high-pressure flow rate and improve the impact resistance of the pipe fitting body.

[0010] Compared with the prior art, the new hydraulic pipe fitting has a simple and reasonable structure, a stable and reliable connection, and utilizes the slow-flow ribs and rubber strip structure design on the inner wall of the pipe fitting body to effectively slow the flow of oil under high-pressure impact and smoothly guide the transmission, thereby greatly improving the impact resistance of the pipe fitting body, reducing the probability of damage and leakage of the pipe fitting body, and increasing the actual service life. At the same time, the pipe fitting body inlaid with the rubber strip structure has a silent noise reduction effect. BRIEF DESCRIPTION OF THE DRAWINGS

The plurality of slow-flow ribs 2 are arranged in a spiral structure and distributed on the inner circumferential wall of the pipe fitting body 1 in sequence. A rubber strip 3 for improving impact resistance and having a silent effect is arranged between two adjacent slow-flow ribs 2. The rubber strip 3 is embedded and installed on the inner circumferential wall of the pipe fitting body 1. Connecting flanges 4 for improving connection strength are arranged at both ends of the pipe fitting body 1. The plurality of slow-flow ribs 2 are arranged in a sheet-like structure and are integrally formed with the inner circumferential wall of the pipe fitting body 1.

[0016] The above structure is simple and reasonable, the connection is stable and reliable, and the flow-slowing ribs 2 and the rubber strips 3 on the inner wall of the pipe body 1 are used to effectively slow down the flow of oil under high-pressure impact and smoothly guide the transmission, which greatly improves the impact resistance of the pipe body 1, reduces the probability of damage and leakage of the pipe body 1, and increases the actual service life. At the same time, the pipe body 1 inlaid with the rubber strips 3 structure has a silent noise reduction effect.

[0017] Preferably, in order to prevent the rubber strips 3 from being damaged by oil corrosion, the surfaces of several rubber strips 3 are plated with an anti-corrosion coating for preventing oil corrosion, and the rubber strips 3 are located between two adjacent slow-flow ribs 2 .

These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
