Description

Technical Field

[0001] The utility model belongs to the field of pipe joints, and in particular relates to a sealing and filling structure for a pipe joint. Background Art

[0002] The water pipe joint in the prior art is a common component in pipelines, which plays the role of connecting and sealing pipelines.

[0003] The Chinese patent application number CN202121594836.0 discloses a water pipe joint with reliable sealing, including a first pipe joint, a second pipe joint and an elastic seal. One of the first pipe joint and the second pipe joint is provided with a boosting ring groove, and the outlet of the boosting ring groove faces the joint end face of the other pipe joint. An elastic seal is placed at the outlet of the boosting ring groove. The inlet of the boosting ring groove is connected to the pipe. The first pipe joint is fixedly connected to the second pipe joint. The first pipe joint and the second pipe joint are tightly pressed against the elastic seal. When water flows through the first pipe joint and the second pipe joint, the water in the pipe flows from the inlet of the boosting ring groove to its outlet. The elastic seal is deformed under the action of water pressure, thereby causing the elastic seal to deform to fill the gap between the first pipe joint and the second pipe joint, thereby achieving the purpose of enhanced sealing and improving the reliability of sealing. It has the characteristics of simple structure and strong practicality.

[0004] However, in actual use, the pipe joint refers to the component that connects the pipeline in the hydraulic system or installs the pipeline on the hydraulic component. Generally speaking, the hydraulic pressure of the pipeline is relatively high, and the impact of a sudden burst of the hydraulic pipeline is very large. Therefore, the pipe joints of the hydraulic system need to withstand great pressure. In particular, when two pipe joints are connected, a certain gap is reserved between them to effectively fix the pipeline. The nuts are then tightened to secure them. Otherwise, the two pieces will interfere with each other and the pipeline cannot be effectively fixed. However, if the pressure is too high, the sealing ring will be squeezed out of the reserved gap between the two pipe joints.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0010] The resistance shell includes a protective ring, which is symmetrically arranged on the outside of the connecting pipe 1 and the connecting pipe 2, and the two protective rings are wrapped around the sealing ring. Filling materials are arranged on both sides between the two protective rings, and fixing wires are arranged on both sides of the two protective rings. An O-ring is arranged inside the filler.

[0011] Optionally, both the connecting pipe 1 and the connecting pipe 2 are connected to external objects, and the outsides of the connecting pipe 1 and the connecting pipe 2 are provided with interference grooves.
