AI Technical Summary
The sealing ring structure of existing hydraulic pipe joints is unstable and easily damaged after connection, resulting in insufficient sealing.
A new hydraulic pipe joint including a joint body, external thread, partition plate and multi-layer sealing device is designed. The sealing device consists of a sealing ring, a first layer, a second layer and a third layer sealing lip, and a third layer sealing lip The bending extends to press the seal ring to form a V-shaped structure and an inner pressure groove to relieve the pressing force.
The stability and sealing of the sealing structure are achieved, preventing damage to the sealing device and ensuring efficient sealing between the pipe fittings and the joints.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of joints and relates to a pipe joint, in particular to a novel hydraulic pipe joint. Background Art
[0002] After the existing hydraulic pipe joint is connected to the pipe fitting, a sealing ring is installed between the joint and the pipe fitting to achieve a sealing effect. However, the existing sealing ring structure is basically a ring structure, which is easy to cause structural instability due to its simple structure and is easy to be damaged after the joint and the pipe fitting are pressed together. Summary of the invention
[0003] The utility model aims to solve the above problems existing in the prior art and provides a new hydraulic pipe joint with a stable sealing structure and strong sealing performance.
[0004] The purpose of the utility model can be achieved through the following technical solutions: A new type of hydraulic pipe joint, including a joint body, characterized in that both ends of the joint body are provided with external threads, the middle part of the joint body is provided with a spacer, and both sides of the spacer are provided with sealing devices that seal with the pipe fitting;
[0005] The sealing device includes a sealing ring, a first layer of sealing lip formed on the sealing ring and a second layer of sealing lip formed on the first layer of sealing lip, an internal pressure groove is provided between the first layer of sealing lip and the second layer of sealing lip, a third layer of sealing lip is provided on the second layer of sealing lip, and the end of the third layer of sealing lip is bent and extended toward the sealing ring and can be pressed tightly against the sealing ring.
[0006] In the above-mentioned novel hydraulic pipe joint, the first layer of sealing lip and the second layer of sealing lip form a V-shaped structure.
[0007] Compared with the prior art, the novel hydraulic pipe joint has the advantages of efficient sealing and stable sealing structure. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is a stereogram of the novel hydraulic pipe joint.
[0009] Figure 2 It is a cross-sectional view of the novel hydraulic pipe joint.
[0010] In the figure, 1. joint body; 2. external thread; 3. spacer; 4. sealing ring; 5. first layer sealing lip; 6. second layer sealing lip; 7. third layer sealing lip; 8. sealing device. DETAILED DESCRIPTION
[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0012] like Figure 1 , Figure 2 As shown, the new hydraulic pipe joint comprises a joint body 1, both ends of which are provided with external threads 2, a spacer 3 is provided in the middle of the joint body 1, and sealing devices 8 are provided on both sides of the spacer 3 to seal with the pipe fitting.
[0013] To further explain, the sealing device 8 includes a sealing ring 4, a first layer of sealing lip 5 formed on the sealing ring 4 and a second layer of sealing lip 6 formed on the first layer of sealing lip 5, an internal pressure groove is provided between the first layer of sealing lip 5 and the second layer of sealing lip 6, and a third layer of sealing lip 7 is provided on the second layer of sealing lip 6, and the end of the third layer of sealing lip 7 is bent and extended toward the sealing ring 4 and can be pressed against the sealing ring 4. After the pipe fitting is connected, the pipe fitting is pressed against the sealing device 8. Due to the new structure of the sealing device 8, its internal pressure groove acts as a force release groove, which can reduce the pressing force on the sealing device 8 between the pipe fitting and the partition plate 3, thereby preventing the sealing device 8 from being damaged; in addition, after the pipe fitting is connected to the sealing device 8 and internal pressure is formed, the end of the third sealing lip is pressed against the sealing ring 4, thereby achieving efficient sealing between the pipe fitting and the joint body 1.
[0014] Preferably, the first sealing lip 5 and the second sealing lip 6 form a V-shaped structure.
[0015] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0016] Although the present invention uses more terms such as joint body 1, external thread 2, spacer 3, sealing ring 4, first sealing lip 5, second sealing lip 6, third sealing lip 7, sealing device 8, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
