Insulation pipe joint

Abstract

The invention relates to a thermal insulation pipe joint, which at least comprises a thermal insulation body integrally formed by a foam thermal insulation material, wherein the thermal insulation body is formed according to the shape of a pipe joint such as a crossed pipe joint, a Y-shaped pipe joint, a T-shaped pipe joint, an arc-shaped pipe joint and a straight pipe joint. Therefore the thermal insulation body is provided with a first element and a second element, in addition, mutually corresponding installing grooves are formed in the first element and the second element, the pipe joint is arranged in the installing grooves by using the installing grooves of the first element or the second element, then, the second element or the first element is covered, in addition, adhesive tapes are used for binding the outer side of the thermal insulation body, the pipe joint can be completely covered, and the flowing of liquid or gas in the pipe joint is ensured.

Description

technical field [0001] The invention relates to heat preservation pipe joints, especially a pipe joint based on the shape of a cross-shaped pipe joint, a Y-shaped pipe joint, a T-shaped pipe joint, an arc-shaped pipe joint, a straight pipe joint, etc. The shape of the inner tube of the pipe is an insulation body formed integrally with foam insulation material, and the first element and the second element of the insulation body are symmetrically formed with a setting groove for the pipe joint. After that, the second element or the first element Cover and tape the outer side of the insulation body to completely cover the pipe joint to ensure the flow of liquid or gas inside the pipe joint and the insulation pipe. Background technique [0002] According to known thermal insulation pipe joints, such as the Chinese Taiwan Publication No. 200424468 invention patent titled "Three-in-One Foaming Thermal Insulation Pipe Joint", it is mainly to fill with a foam layer between the 900 p...

AI Technical Summary

Problems solved by technology

In the aforementioned known technology, because the foam layer is directly coated on the outside of the 900 pipe joint, it will directly adhere to the outer surface of the inner pipe. or when the insulation pipe joint is connected with other equipment, the insulation pipe must be arranged on the inboard of the insulation pipe joint, causing the pipe diameter to shrink inwards, increasing the flow pressure of liquid or gas, and because of the aforementioned known 900 insulation pipe joints , has been formed directly with the foam layer. When the external pipe fittings are connected with the known 900 thermal insulation pipe joints, it is impossible to know whether the sealing has been completed, resulting in the leakage of the 900 thermal insulation pipe joints and the external pipe fittings.
