Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, an embodiment of the present invention provides a technical solution: the utility model provides a special pipe of high temperature resistant CPVC, includes body 1, body 1 comprises basic unit, high temperature resistant layer, compressive layer and insulating layer, high temperature resistant level is located the outer wall of body 1, high temperature resistant layer comprises thermal barrier coating, compressive layer, insulating layer and basic unit distribute in proper order in the inside of body 1, compressive layer comprises tungsten filament circle 3, the insulating layer comprises potsherd 4.

The pressure resistant layer and the heat insulation layer are fixed through heat insulation aerogel. The heat-insulating aerogel can also have a good bonding effect when meeting high temperature.

The heat insulation coating is formed by mixing glass fibers and asbestos fibers. Glass fibers and asbestos fibers have good thermal insulation properties.

The ceramic plate 4 is matched with the pipe body 1 in shape. The consistency of the mosaic structure is ensured.

The base layer is made of chlorinated polyvinyl chloride. The PVC material has the advantages of good heat resistance, chemical corrosion resistance, anti-aging performance, flame retardance, higher heat distortion temperature and the like, not only has many excellent performances of PVC, but also has good flame retardance and low smoke generation characteristic, can resist most of acid, alkali and salt, is obviously superior to other plastics in heat resistance (can be improved by 20-40 ℃ compared with common PVC), and has better Vicat heat resistance temperature than other thermoplastic plastics.

The working principle is as follows: this CPVC body is the combined nature body, thermal barrier coating on the 1 outer wall of body, the outer wall to body 1 provides the protection, the external temperature has been kept apart, the external temperature of having avoided leads to the fact the heat transfer to body 1, the ageing degree of body with higher speed, 1 inside tungsten filament circle 3 of body plays the effect of support to whole body 1, can strengthen the compressive capacity of body 1, can not receive external force influence, cause body 1 to warp, 1 inside potsherd 4 of body, potsherd 4 has the non-heat-conducting characteristic, play the effect of 1 inside and outside isolation of body, the condition of heat transfer appears between the inside and outside temperature of body 1 has been avoided.

The utility model discloses a body 1, thermal-insulated coating 2, tungsten filament circle 3, potsherd 4, the part is general standard component or the part that technical staff in this field knows, its structure and principle all are this technical staff can learn through the technical manual or through conventional experimental method to know, the problem that the utility model solves is that present CPVC body structure is comparatively simple, though has good high temperature resistance, its heat-resisting characteristic depends on the temperature range, because the interior circuit that is equipped with of CPVC, also appears ageing, damaged phenomenon easily for a long time receiving high temperature influence, the utility model CPVC body adopts the mode of the combination of thermal-insulated coating, tungsten filament circle and potsherd, makes the CPVC pipe be the composite body, and the thermal-insulated coating can resist the external temperature, and the tungsten filament circle provides the support effect to the body whole when having good heat resistance, has improved the compressive degree of body, the ceramic wafer plays a role in isolating the temperature inside and outside the tube body, and avoids the phenomenon of heat transfer of the tube body.
