Description

Technical Field

[0001] This utility model relates to the field of PP pipe technology, and in particular to a highly conductive PP pipe that prevents sparks. Background Technology

[0002] PP pipe is a non-toxic, hygienic, high-temperature resistant, and recyclable pipe type. It is mainly used in indoor hot and cold water supply systems in buildings and is also widely used in heating systems. PP pipe is also used in liquid distribution devices in chemical production equipment, corrosive liquid transportation in oil extraction systems, and process pipelines in chlor-alkali projects. High-conductivity PP pipe is mainly used for electrostatic protection and fluid transportation, especially in flammable, explosive, and high electrostatic risk areas. Its connection methods include welding, edge welding, and dissimilar material connection.

[0003] Chinese Patent Publication No. CN211289036U discloses a fire-retardant PP pipe, including a support, a connecting hole at the top of the support, a first connecting sleeve fixedly connected to the inner wall of the connecting hole, a pipe body fixedly connected to the top of the first connecting sleeve, a flame-retardant layer fixedly connected to the inner wall of the pipe body, an inner layer fixedly connected to the inner wall of the flame-retardant layer, a second connecting sleeve fixedly connected to one end of the pipe body, a fixing groove at the top of the support, a water tank fixedly connected to the inner wall of the fixing groove, a spray pipe fixedly connected to the top of the water tank, a first fireproof outer shell fixedly connected to the outer wall of the pipe body, and a second fireproof outer shell fixedly connected to the outer wall of the pipe body. This fire-retardant PP pipe achieves good fire resistance, solving the problem of poor fire resistance in general PP pipes, improving the flame-retardant performance of the pipe body, effectively extending the service life of the PP pipe, improving its practicality, and providing good performance.

[0004] However, in actual use, the PP pipes mentioned above have insufficient flame retardancy, weak rigidity, and poor thermal insulation, making them susceptible to damage from external environmental factors. They also cannot effectively prevent the hazards caused by combustion, increasing safety risks and thus reducing their effectiveness. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly conductive, spark-proof PP tube.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a highly conductive spark-proof PP pipe, comprising a PP pipe body, an insulating sleeve fixedly sleeved on the outer wall of the PP pipe body, an assembly sleeve fixedly sleeved on the outer wall of the insulating sleeve, and an assembly assembly connected to the outer wall of the assembly sleeve.

[0007] A silicon graphene plate is fixedly connected between the two sides of the inner wall of the insulation sleeve, and an insulation component is connected to the top of the silicon graphene plate. A flame-retardant component is installed inside the sleeve.

[0008] As a further description of the above technical solution: the assembly assembly includes two assembly kits fixedly sleeved on the outer wall of the assembly kit tube, and an assembly hollow tube is fixedly connected between the two assembly kits, which serves to isolate and retard flames.

[0009] As a further description of the above technical solution: the outer wall of the assembly pipe is wrapped with assembly reinforcing ribs, and multiple assembly reinforcing horizontal ribs are fixedly connected between the two assembly kits. The strength of the PP pipe body is enhanced by the combination of assembly reinforcing ribs and assembly reinforcing horizontal ribs.

[0010] As a further description of the above technical solution: the insulation component includes an expanded perlite layer fixedly connected to the top of the graphene board layer, and a rock wool board layer is fixedly connected to the top of the expanded perlite layer. The expanded perlite layer serves to insulate the PP pipe body.

[0011] As a further description of the above technical solution: the flame-retardant component includes a magnesium oxide board layer fixedly connected between the inner walls of the PP pipe and both sides thereof, and a steel structure fireproof coating layer fixedly connected to the top of the magnesium oxide board layer. The steel structure fireproof coating layer serves to achieve the purpose of flame retardant insulation of the PP pipe body.

[0012] As a further description of the above technical solution: a fireproof gypsum board layer is fixedly connected to the top of the fireproof coating layer of the steel structure, a vermiculite board layer is fixedly connected to the top of the fireproof gypsum board layer, and a ceramic fiber fireproof cloth layer is fixedly connected to the top of the vermiculite board layer. The ceramic fiber fireproof cloth layer provides flame retardancy and heat insulation.

[0013] This utility model has the following beneficial effects:

[0014] The assembly components enable the hollow tube to provide insulation and electrical protection. Furthermore, the assembly components on the tube, through the combination of reinforcing ribs and cross ribs, enhance the strength of the tube, thereby strengthening the PP pipe body and achieving high rigidity. The insulation components provide the magnesium oxide board layer with strong fire resistance. The fire-retardant coating layer on the steel structure expands easily upon exposure to fire, forming a heat insulation layer that protects the structural integrity of the PP pipe body. Simultaneously, the fire-retardant gypsum board layer contains crystalline water, which absorbs heat and decomposes at high temperatures, thus providing heat insulation and flame retardancy for the PP pipe body. The flame-retardant components provide heat insulation for the vermiculite board layer, followed by the flame-retardant and heat-insulating ceramic fiber fireproof cloth layer. This reduces damage from external factors and provides good flame-retardant and heat-insulating properties, thereby improving the overall performance. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-4This utility model provides a high-conductivity, spark-proof PP pipe, comprising a PP pipe body 101, an insulation sleeve 102 fixedly sleeved on the outer wall of the PP pipe body 101, an assembly sleeve 103 fixedly sleeved on the outer wall of the insulation sleeve 102, and an assembly component connected to the outer wall of the assembly sleeve 103. The assembly component strengthens the PP pipe body 101. The assembly component includes two assembly kits 104 fixedly sleeved on the outer wall of the assembly sleeve 103, an assembly hollow tube 105 fixedly connected between the two assembly kits 104, an assembly reinforcing rib 106 wound around the outer wall of the assembly sleeve 103, and multiple assembly reinforcing transverse ribs 107 fixedly connected between the two assembly kits 104. The assembly reinforcing transverse ribs 107 and the assembly reinforcing ribs 106 strengthen the PP pipe body 101.

[0023] A graphene board 203 is fixedly connected between the two sides of the inner wall of the insulation sleeve 102. An insulation component is connected to the top of the graphene board 203. The insulation component includes an expanded perlite layer 204 fixedly connected to the top of the graphene board 203. A rock wool board 205 is fixedly connected to the top of the expanded perlite layer 204. The insulation component serves to insulate the PP pipe body 101.

[0024] The mounting pipe 103 is equipped with a flame-retardant component. The flame-retardant component includes a magnesium oxide board layer 108 fixedly connected to both sides of the inner wall of the mounting pipe 103, a steel structure fireproof coating layer 109 fixedly connected to the top of the magnesium oxide board layer 108, a fireproof gypsum board layer 200 fixedly connected to the top of the steel structure fireproof coating layer 109, a vermiculite board layer 201 fixedly connected to the top of the fireproof gypsum board layer 200, and a ceramic fiber fireproof cloth layer 202 fixedly connected to the top of the vermiculite board layer 201. The flame-retardant component achieves the purpose of flame retardancy.

[0025] Working principle: When in use, first install the PP pipe body 101 with the external pipeline. When the flow is transmitted inside the PP pipe body 101, the insulation sleeve 102 is installed on the PP pipe body 101. At the same time, the silicon graphene board layer 203 inside the insulation sleeve 102 provides insulation and is suitable for high humidity areas. Then, the expanded perlite layer 204 provides good fire resistance. Next, the rock wool board layer 205 serves as an inorganic insulation material. The rock wool board layer 205 is a non-combustible material with good fire resistance and insulation performance.

[0026] Following the insulation sleeve 102, the PP pipe body 101 is insulated and protected. Then, the matching pipe 103 is installed on the insulation sleeve 102. At the same time, the glass magnesium board layer 108 inside the matching pipe 103 is based on inorganic minerals and has strong fire resistance. The steel structure fireproof coating layer 109 is easy to expand and form a heat insulation layer when exposed to fire, which protects the structural integrity of the PP pipe body 101.

[0027] Meanwhile, the fireproof gypsum board layer 200 contains crystal water, which absorbs heat and decomposes at high temperatures, thereby providing heat insulation and flame retardancy for the PP pipe body 101. Subsequently, the vermiculite board layer 201 has high strength and provides heat insulation, and then the ceramic fiber fireproof cloth layer 202 provides flame retardancy and heat insulation.

[0028] Meanwhile, when the PP pipe body 101 is impacted by external factors, the assembled hollow pipe 105 is fixedly sleeved on the outside of the assembled pipe 103 and forms a barrier. The assembled hollow pipe 105, as a high-hardness plastic material, provides insulation and prevents electric shock. Then, the assembly components on the assembled pipe 103 enhance the strength of the assembled pipe 103 through the assembly reinforcing ribs 106 and the assembly reinforcing transverse ribs 107. This also enhances the strength of the PP pipe body 101 on the assembled pipe 103, resulting in higher rigidity and reducing the risk of breakage of the PP pipe body 101.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
