Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] The invention provides a thermal insulation elbow, which includes two parts that are mirror-symmetrical and airtightly connected, and each part is an outer protective pipe layer 2, an insulating layer 1 and an elbow layer 3 from the outside to the inside in sequence, and the outer protective pipe layer 2 and the elbow layer 3 are pressed into an integrated cavity structure, and the insulation layer 1 is filled in the cavity. The material of the outer protective tube layer 2 and the bent tube layer 3 is metal or polyethylene. The insulation layer 1 is made of polyurethane foam. The bent pipe layer 3 includes bent pipe sections and straight pipe sections extending from the bent pipe sections. The straight pipe section can be directly connected with the heat preservation straight pipe, and the assembly is very convenient. The connection of the two parts is one of...

Abstract

The invention provides a heat preservation bend. The bend comprises two parts which are in mirror symmetry and are in seal connection, each part sequentially comprises an outer protection pipe layer,a heat preservation layer and a bent pipe layer from outside to inside, the outer protection pipe layer and the bent pipe layer are pressed to an integrated cavity structure, and a cavity is filled with the heat preservation layer. The integrated structure is adopted, and the phenomena that in the prior art, the heat preservation bend is prone to cracking and detaching can be avoided.

Description

technical field [0001] The invention relates to an elbow, in particular to an integrally formed thermal insulation elbow. Background technique [0002] Insulation operation is a routine operation in industrial production. When changing the direction of the pipeline, it is necessary to use the insulation elbow. At present, the thermal insulation elbows used in domestic industrial production are basically welded directly during on-site construction, which not only takes a long time for construction, but also has poor sealing performance, and is also prone to cracks and disjoint phenomena, which seriously shortens the service life and affects the thermal insulation effect. , increasing production costs. [0003] In the existing production, there is an urgent need for a thermal insulation elbow that is not easy to open and disconnect, and has better performance. To ensure the long-term and efficient operation of production. Contents of the invention [0004] In order to s...
