Insulation shell of three-way pipe for thermal pipeline

Abstract

The invention provides an insulation shell of a three-way pipe for a thermal pipeline. An all-plastic pipe sleeve is arranged outside the three-way pipe. An upper half pipe sleeve body and a lower half pipe sleeve body in the same shape as the upper half pipe sleeve body are buckled so as to form the all-plastic pipe sleeve. The outer surface of the upper half pipe sleeve body or the lower half pipe sleeve body of the all-plastic pipe sleeve is provided with a left connecting port, a right connecting port and a lower connecting port which correspondingly wrap an upper half pipe or a lower halfpipe of three connecting pipe bodies of the three-way pipe. The upper half pipe sleeve body or the lower half pipe sleeve body is provided with a semi-circular-shaped plate perpendicular to the connecting pipe bodies at pipe openings of the left connecting port, the right connecting port and the lower connecting port. The inner diameter of a circle formed by the semi-circular-shaped plates is slightly larger than or equal to the diameter of the three connecting pipe bodies of the three-way pipe. The end, buckled with the lower half pipe sleeve body, of the upper half pipe sleeve body is provided with a plurality of buckles and grooves matched with the buckles, and therefore, the upper half pipe sleeve body and the lower half pipe sleeve body are buckled into a whole.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to an all-plastic thermal pipeline tee with heat preservation function, that is, a heat insulation shell of a tee pipe fitting. Background technique [0002] As a device for conveying gas, liquid or fluid with solid grains, tee pipes are widely used in various conveying equipment, hydraulic engineering and industrial devices to realize the communication between pipes. [0003] Existing tee pipe fittings with thermal insulation performance are mostly made of metal or plastic, and the outside of the metal or plastic tee pipe fittings needs to be wrapped with an insulation layer, and the requirements for this insulation layer are quite high, and the temperature of the fluid inside the pipe and pipe fittings may be close to 100 ℃, and the ambient temperature may be -20 ℃, such a temperature difference needs to be present, and it is more troublesome to install, especially at the outlet...

Problems solved by technology

[0003] Existing tee pipe fittings with thermal insulation performance are mostly made of metal or plastic, and the outside of the metal or plastic tee pipe fittings needs to be wrapped with an insulation layer, and the requirements for this insulation layer are quite high, and the temperature of the fluid inside the pipe and pipe fittings may be close to 100 ℃, and the ambient temperature may be -20 ℃, such a temperature difference needs to be present, and it is more troublesome to install, especially at the outlet of the tee, which is also relatively easy to rust, and it is more troublesome to replace, but there is an all-plastic pipe three Most of them do not have the function of heat preservation, or the devices with heat preservation function have poor effect and complicated installation
