Description

Technical Field

[0001] The utility model belongs to the technical field of composite pipes, in particular to a flame-retardant polymer composite pipe. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually the fluid is pressurized by blowers, compressors, pumps and boilers, and then flows from the high-pressure part of the pipeline to the low-pressure part. The fluid can also be transported by its own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.

[0003] Most of the existing pipelines are directly exposed to the outside when in use. When subjected to external impact, the pipelines are directly subjected to the impact force and are easily damaged, resulting in a short service life of the pipelines. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a flame retardant polymer composite pipe, which effectively solves the problem that the current pipe is easily damaged due to the impact force directly subjected to external impact.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flame-retardant polymer composite pipe, comprising a pipe body, a protective mechanism is installed on the outer side of the pipe body;

[0006] The protective mechanism includes two fixed plates symmetrically fixed on the outside of the pipeline body. Two protective plates are symmetrically arranged on the outside of the pipeline body. Slide plates are fixedly installed on both sides of the two protective plates. The slide plates are movably sleeved inside the fixed plates. Springs are fixedly connected between the two slide plates at equal distances.

[0007] Preferably, arc-shaped rubber plates are fixedly installed at equal distances on the inner sides of the two protection plates, and each arc-shaped rubber plate is fixed to the outer side of the pipeline body.

[0008] Preferably, the pipe body includes an inner layer, a polymer flame retardant layer is bonded to the outer side of the inner layer, a reinforcing layer is bonded to the outer side of the polymer flame retardant layer, an outer layer is bonded to the outer side of the reinforcing layer, and two fixing plates and each arc rubber plate are fixed to the outer side of the outer layer.

[0009] Preferably, the inner layer and the outer layer are both made of plastic material.

[0010] Preferably, the polymer flame retardant layer is made of polyvinylidene chloride material, and the reinforcing layer is made of fiber material.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The utility model facilitates the two protective plates to directly bear the impact force through the cooperation between the arc-shaped rubber plate and the protective plate, and the slide plate and the spring. Since the arc-shaped rubber plate and the spring both have elastic force, they can partially absorb the impact force, which facilitates buffering of the two protective plates, thereby preventing the pipeline body from being directly impacted and damaged;

[0013] (2) The new type of pipe is provided with a polymer flame retardant layer and a reinforcing layer between the inner layer and the outer layer. The polymer flame retardant layer is made of polyvinylidene chloride material, thereby facilitating improving the flame retardant performance of the pipe body. At the same time, the outer layer is made of fiber material, thereby facilitating improving the overall strength of the pipe body. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Embodiment 1, by Figure 1-2The utility model includes a pipeline body 1, a protective mechanism 2 is installed on the outside of the pipeline body 1, the pipeline body 1 includes an inner layer 101, a polymer flame retardant layer 102 is bonded to the outside of the inner layer 101, a reinforcing layer 103 is bonded to the outside of the polymer flame retardant layer 102, an outer layer 104 is bonded to the outside of the reinforcing layer 103, two fixing plates 201 and each arc-shaped rubber plate 202 are fixed to the outside of the outer layer 104, the inner layer 101 and the outer layer 104 are made of plastic material, the polymer flame retardant layer 102 is made of polyvinylidene chloride material, and the reinforcing layer 103 is made of fiber material;

[0023] When in use, a polymer flame retardant layer 102 is firstly arranged on the outer side of the inner layer 101. The polymer flame retardant layer 102 is made of polyvinylidene chloride material, which has flame retardant properties and can effectively suppress the occurrence and spread of fire. A reinforcing layer 103 is arranged on the outer side of the polymer flame retardant layer 102. The reinforcing layer 103 is made of fiber material to improve the overall strength of the pipeline body 1.

[0024] Specifically, by Figure 3-4 It is given that the protection mechanism 2 includes two fixed plates 201 symmetrically fixed on the outside of the pipeline body 1, two protection plates 203 are symmetrically arranged on the outside of the pipeline body 1, and slide plates 205 are fixedly installed on both sides of the two protection plates 203. The slide plates 205 are movably sleeved inside the fixed plates 201, and springs 204 are fixedly connected between the two slide plates 205 at an equal distance. Arc rubber plates 202 are fixedly installed on the inner sides of the two protection plates 203 at an equal distance, and each arc rubber plate 202 is fixed on the outside of the pipeline body 1;

[0025] In the use state, when the pipeline body 1 is impacted by the outside world, the impact force directly acts on the protective plate 203. At the same time, the arc-shaped rubber plate 202 is deformed by pressure and drives the slide plate 205 to slide in the fixed plate 201. At this time, each spring 204 is deformed. Since the spring 204 and the arc-shaped rubber plate 202 are elastic, the impact force is partially absorbed and the protective plate 203 is buffered, finally avoiding the pipeline body 1 from being directly impacted and damaged.
