Description

Technical Field

[0001] The utility model relates to the technical field of PVC plastic pipes, in particular to a heat-insulating PVC plastic pipe. Background Art

[0002] In modern industry, construction, municipal administration and many civil fields, PVC plastic pipes are widely used to transport various fluid media such as water, heating, air conditioning refrigerants, chemical raw materials, etc. due to their many advantages such as low cost, corrosion resistance and easy installation. However, with the continuous improvement of various industries' requirements for energy utilization efficiency, process stability and user comfort, the inherent defects of PVC plastic pipes in heat transfer have gradually been exposed, and the demand for insulation has become more urgent. In the building heating system, hot water needs to be transported from the heat source to the radiator in each room through pipes. If ordinary PVC plastic pipes are used, the hot water will lose heat seriously during the long-distance transmission process, resulting in the indoor temperature of the end user being difficult to reach the expected standard. Not only does it waste a lot of energy for continuous heating to replenish the lost heat, but it also affects the heating experience of residents.

[0003] Existing PVC plastic pipes are generally connected by glue. Although the sealing effect is good in the short term, the plastic pipes exposed to the open air are exposed to the wind and rain of nature, which greatly reduces the sealing effect. At the same time, it is extremely difficult to dismantle the indoor plastic pipes. What's worse, the plastic pipes will be damaged during the disassembly process and cannot be recycled, which increases the cost.

[0004] Therefore, it is urgent to provide a kind of thermal insulation PVC plastic pipe to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the disadvantages of the above-mentioned prior art and provide a heat-insulating PVC plastic pipe.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide an insulated PVC plastic pipe, including a pipe body, the outer wall of the pipe body is fixedly connected to an insulation sleeve, the inner wall of the insulation sleeve is fixedly connected to a first insulation layer, the inner wall of the first insulation layer is fixedly connected to a second insulation layer, the inner wall of the second insulation layer is fixedly connected to a third insulation layer, and locking components are installed at both ends of the outer wall of the pipe body.

[0007] The present invention is further configured as follows: the inner wall of the first thermal insulation layer is tightly fitted to the outer wall of the second thermal insulation layer, and the first thermal insulation layer is made of aluminum silicate fiber.

[0008] The above technical solution can greatly reduce the rate of heat loss to the environment outside the pipe, ensuring that the medium can be transported to the destination at a relatively stable temperature. In the case of transporting cold medium, it can effectively prevent external heat from entering the pipe and maintain a low temperature environment inside the pipe, which helps to improve the insulation efficiency of the entire pipeline system and reduce energy consumption.

[0009] The utility model is further configured as follows: the inner wall of the second thermal insulation layer is closely fitted with the outer wall of the third thermal insulation layer, and the second thermal insulation layer is made of polyurethane foam material.

[0010] Through the above technical solution, there are no weak points in insulation caused by gaps or poor fitting, ensuring that no matter where the water pipe is, it can maintain stable and efficient insulation performance, thereby ensuring the normal operation of the entire hot water supply or water delivery system.

[0011] The utility model is further configured as follows: the inner wall of the third thermal insulation layer is matched with the outer wall of the pipeline body, and the third thermal insulation layer is made of rubber-plastic sponge material.

[0012] Through the above technical solution, cold and hot media can be effectively isolated, cold loss and heat loss can be reduced, energy consumption can be reduced, and the temperature of the medium in the pipeline can be maintained stable. At the same time, it can also adapt to the deformation of the pipeline caused by temperature, pressure or external environmental factors, ensuring that the insulation effect is long-lasting and stable.

[0013] The utility model is further configured as follows: the locking assembly includes a plurality of locking blocks fixedly connected to one side of the outer wall of the pipe body, a rubber ring fixedly connected to the other side of the outer wall of the pipe body, a mounting ring fixedly connected between the two sides of the rubber ring, a rotating tube rotatably connected to the outer wall of the mounting ring, a plurality of sliding grooves are provided on the inner wall of the rotating tube, and a locking groove is provided on one side of the inner wall of each of the plurality of sliding grooves.

[0014] Through the above technical solution, first slide one side of the locking block of another PVC plastic tube into the corresponding slide groove until multiple locking blocks are fitted with the inner wall of the corresponding locking groove, and then rotate the rotating mounting ring clockwise along the outer wall of the rubber ring to rotate the locking block into the locking groove, and then connect the PVC plastic tubes in sequence through this step.

[0015] The utility model is further configured as follows: the outer wall of the rubber ring matches the inner wall of the installation ring, and the outer wall of the installation ring fits with the inner wall of the rotating tube.

[0016] Through the above technical solution, the tiny gap between the rubber ring and the mounting ring can be filled to form an effective sealing line of defense. Similarly, the outer wall of the mounting ring fits with the inner wall of the rotating tube, which can also minimize the existence of gaps and allow the pipeline to remain stable in a vibration environment, reducing the frequency of maintenance and replacement, and extending the service life of the entire pipeline device.

[0017] The utility model further sets up: the size of multiple lock catch groove is equal with corresponding lock catch block size.

[0018] Through above-mentioned technical scheme, lock catch block can be embedded in lock catch groove tightly, and this close cooperation mode makes PVC plastic pipe form stable connection structure, not only installation process is more smooth and efficient, but also facilitates quick positioning and disassembly and reinstallation of parts in subsequent maintenance and overhaul process.

[0019] The utility model has the advantages that:

[0020] 1. The utility model discloses a lock catch assembly, and the construction personnel need not carry out complex thread tightening, glue pasting or long-time welding operation as in the traditional connection mode, but only need to align the corresponding parts of the water pipe, operate the lock catch assembly, and quickly realize the connection of the water pipe through slight buckling or operation according to a simple locking mechanism, so that the installation time is greatly shortened.

[0021] 2. The utility model discloses a first heat preservation layer, second heat preservation layer and third heat preservation layer, so that the heat loss rate is greatly slowed down, so that hot water can be delivered to the water point at a relatively high temperature, and the energy consumption of the water heater for maintaining water temperature is reduced, and the energy-saving effect is realized.
