Description

Technical Field

[0001] The utility model belongs to the technical field of water supply and drainage, and particularly relates to a detachable PVC pipe fitting with an internal thermal insulation material. Background Technique

[0002] The thermal insulation construction of water supply pipelines is a very important construction node. Improper construction methods and unscientific thermal insulation components may lead to the failure of thermal insulation construction to meet the design and specification requirements, resulting in the failure to achieve the thermal insulation effect of water supply pipelines.

[0003] The traditional method for thermal insulation construction of pipelines is to wrap all pipes, pipe fittings, valves, etc. with thermal insulation materials. Currently, all the cylindrical thermal insulation materials (such as rubber and plastic pipes, polyurethane, etc.) sold in the market are manufactured according to the pipe specifications. As long as the pipe is inserted into the thermal insulation pipe and then sleeved with a PVC pipe, the construction is very convenient. However, for pipe fittings (elbows, tees, crosses, straight-throughs, valves, etc.), they cannot be directly inserted into the thermal insulation pipe. During thermal insulation construction, only the thermal insulation material needs to be split and wrapped around the pipe fittings and then taped. Such construction is very inconvenient, and often some parts of the pipe fittings are not properly wrapped with thermal insulation materials, resulting in the failure to achieve the thermal insulation effect. Especially when maintenance is required, the thermal insulation materials of the pipe fittings (elbows, tees, crosses, straight-throughs, valves, etc.) must be completely removed, and after the maintenance is completed, the thermal insulation needs to be done again, which is both time-consuming and wasteful.

[0004] Therefore, the utility model provides a detachable PVC pipe fitting with an internal thermal insulation material. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a detachable PVC pipe fitting with an internal thermal insulation material, providing a finished thermal insulation component for the above-mentioned background technology water supply pipe fittings (elbows, tees, crosses, straight-throughs, valves, etc.). When the construction of the water supply pipe network is completed, as long as the finished thermal insulation component is installed on the pipe fitting, the thermal insulation construction of the pipe fitting is completed. This finished thermal insulation pipe fitting is detachable, and when maintenance is required, it can be disassembled for operation, and reinstalled after the maintenance is completed. The construction and maintenance are convenient, and the thermal insulation effect is good.

[0006] To achieve the above purpose, the utility model provides the following PVC thermal insulation pipe fitting manufacturing technology: a detachable PVC pipe fitting with an internal thermal insulation material, the PVC pipe fitting is composed of two pieces, assembled by snap-fastening, detachable, and is composed of a PVC pipe fitting, thermal insulation adhesive, a polyurethane thermal insulation layer, and an aluminum foil cushion layer; the pipe fitting is sleeved on the PVC pipe after thermal insulation is done to form a whole; the thermal insulation adhesive layer is painted on the inner surface of the PVC pipe fitting, and its function is to paste the polyurethane thermal insulation material; the thickness of the polyurethane thermal insulation material is related to the diameter of the water supply pipe and the thermal insulation design conditions, and the thickness is not less than 25 mm; the aluminum foil cushion layer has both a thermal insulation function and a function of fixing the polyurethane thermal insulation material, and the outer diameter of the aluminum foil cushion layer is the same as the outer diameter of the water supply pipe.

[0007] Preferably, the detachable PVC pipe fitting with built-in thermal insulation material consists of two pieces and is assembled in a snap-fit manner, making it detachable.

[0016] Next, the manufacturing method of the PVC thermal insulation elbow in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only embodiments of a type of detachable PVC pipe fitting with built-in thermal insulation material of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other types of embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0017] Please refer to the attached drawings. The present utility model provides a PVC thermal insulation component: a detachable PVC pipe fitting with built-in thermal insulation material, which is used for the thermal insulation construction of water supply pipes. The thermal insulation component described in this embodiment is a PVC elbow with built-in thermal insulation material. In the embodiment, the insulated water supply pipe is sleeved into the PVC pipe, and the PVC pipe matches the specification of the PVC pipe fitting 1. A plurality of buckles 11 are provided on the PVC pipe fitting 1, and the outer diameter of the PVC pipe is equal to the inner diameter of the PVC pipe fitting 1. The detachable PVC elbow with built-in thermal insulation material is composed of two pieces and is assembled by buckling, and is detachable. The inner surface of the PVC pipe fitting 1 is coated with a thermal insulation adhesive layer 2, and a polyurethane thermal insulation layer 3 is pasted on the thermal insulation adhesive layer 2. The thermal insulation adhesive 2 can adapt to different temperature conditions, and its function is to paste the polyurethane thermal insulation layer 3. The thickness of the thermal insulation layer is not less than 25 mm. An aluminum foil cushion layer 4 is arranged between the polyurethane thermal insulation layer and the outer surface of the water supply pipe and is closely attached to the outer surface of the water supply pipe. Pasting the aluminum foil cushion layer 4 on the inner surface of the thermal insulation layer has both the function of thermal insulation and the function of fixing the polyurethane thermal insulation material.

[0018] During the thermal insulation construction of the water supply pipe, after the water supply pipe is wrapped with thermal insulation material by the traditional method and then sleeved with a PVC pipe, the thermal insulation construction of the pipe only needs to buckle the finished thermal insulation component provided by the present utility model on the water supply pipe fitting.
