Abstract
The invention relates to a flexible polyurethane heat preservation pipe fitting tee joint and a manufacturing method. According to heat preservation pipe fittings used at present, work pipelines are basically made of steel and hard plastic materials, no flexible work pipes are achieved especially for pipe fittings of pipelines with the nominal diameter lower than 150 mm, and heat preservation pipe fittings suitable for flexible work pipelines do not exist neither. The flexible polyurethane heat preservation pipe fitting tee joint comprises a horizontal work pipe (1). A vertical work pipe (2) is arranged above the middle position of the horizontal work pipe. A heat preservation layer is arranged between the horizontal work pipe and a horizontal outer protection pipe (3). A heat preservation layer is arranged between the vertical work pipe and a vertical outer protection pipe (4). The inner diameter of the horizontal work pipe communicates with the inner diameter of the vertical work pipe, and the horizontal work pipe and the vertical work pipe are the same in size. The flexible polyurethane heat preservation pipe fitting tee joint and the manufacturing method are provided.

Top is provided with vertical instrumentation tubes, has heat-insulation layer, described vertical work between described horizontal operation pipe and horizontal outer protection tube
Manage and vertically have between outer protection tube heat-insulation layer, described horizontal operation pipe communicate with described vertical work bore and
It is equivalently-sized.
Described flexible polyurethane heat-insulating pipe fitting threeway, described horizontal operation pipe, described vertical instrumentation tubes are using poly-
Urethane plastic foam is incubated material, and described horizontal outer protection tube, described vertical outer protection tube adopt polyethylene material.
Described flexible polyurethane heat-insulating pipe fitting threeway, the partition of described horizontal operation pipe and described horizontal outer protection tube
Thick uniform and coaxial, described horizontal operation pipe, described vertical instrumentation tubes are in the range of DN15mm-150mm.
A kind of threeway of flexible polyurethane heat-insulating pipe fitting and preparation method, the method comprise the steps：
It is first from the polyethylene outer protective pipe with flexible structure, flexible working pipeline, flexible with what is arbitrarily can bent
Soft thermal insulating pipe；
Three-port structure is made, is pinpointed on pipeline, according to outer protection tube diameter, is opened on outer protection tube surface and take circular hole, by plasticized polyurethane
After strand foam heat-insulation layer perforate, remove the polyurethane for drilling through position, cleaning spills instrumentation tubes, changes and the same caliber size of instrumentation tubes
Hole making drill, open on service pipe and take circular hole, then using hot-melt technology, respectively to osseotomy site and the instrumentation tubes of straight length
Heating and melting, it is synchronous that straight length is inserted into osseotomy site, using highdensity polyurethane combined material to joint portion after natural cooling
