DETAILED DESCRIPTION
[0017] Embodiment 1:
[0018] like Figure 1 As shown, this embodiment proposes: a durable, corrosion-resistant and enhanced indoor fire hydrant, comprising a bolt body 1, and an anti-corrosion component 2 fixedly arranged on the inner side and / or the outer side of the bolt body 1 (that is, the anti-corrosion component 2 can be arranged on the inner side of the bolt body 1, or the outer side of the bolt body 1, or on both the inner side and the outer side of the bolt body 1);
[0019] The anti-corrosion component 2 includes an epoxy zinc-rich primer layer 21, an epoxy micaceous iron intermediate paint layer 22 and a fluorocarbon topcoat layer 23 which are sequentially bonded and fixed, and the epoxy zinc-rich primer layer 21 is fixed on the inner side and / or the outer side of the plug body 1 (providing a more balanced and outstanding performance in terms of cathodic protection, interlayer adhesion, weather resistance and chemical resistance, etc., and is particularly suitable for use in fire hydrants in industrial heavy anti-corrosion areas with high requirements);
[0020] Epoxy zinc-rich primer layer 21: It is applied first. Its main function is to provide cathodic protection for metal surfaces such as steel, and to prevent the substrate from rusting through the sacrificial anode effect of zinc powder. At the same time, the good adhesion of epoxy resin enables it to fit tightly on the metal surface, forming an effective anti-corrosion barrier.
[0021] Epoxy micaceous iron intermediate paint layer 22: coated outside the epoxy zinc-rich primer layer 21, the main function of which is to increase the thickness of the entire coating system, improve the anti-corrosion performance and shielding effect, and prevent moisture and oxygen from penetrating the coating to reach the metal surface; in addition, the micaceous iron pigment can improve the mechanical strength and weather resistance of the paint film;
[0022] Fluorocarbon topcoat layer 23: Finally, it is coated on the outside of the epoxy micaceous iron intermediate paint layer 22. The topcoat has super high weather resistance, chemical corrosion resistance and self-cleaning properties. It can effectively resist the influence of various harsh environmental factors such as ultraviolet radiation, wind and rain erosion, etc., ensuring that the appearance of the fire hydrant is long-lasting and bright, while further enhancing the overall anti-corrosion ability and extending the service life of the fire hydrant;
[0023] Epoxy coatings have strong adhesion to metal surfaces and good compatibility between layers. The resulting coating system has strong integrity and is not prone to interlayer delamination. From the sacrificial anode protection of the bottom layer to the ultra-weather resistant protection of the surface layer, it provides a complete set of anti-corrosion solutions that are suitable for fire hydrants that are exposed to harsh environments for a long time.
[0024] Embodiment 2:
[0025] like Figure 1 As shown, the difference from Example 1 is that: it also includes that the plug body 1 includes a water outlet pipe 3 (as shown in the figure, the water outlet pipe 3 is a part of the plug body 1, which is used to connect a fire hose during use, etc.).
[0026] The water outlet pipe 3 is provided with a sealing component 4 to seal the water outlet pipe 3 , so as to block the water outlet pipe 3 and seal the connection between the inside and outside of the plug body 1 when not in use.
[0027] In order to realize the implementation and use of the above-mentioned closing and guarding assembly 4, it is proposed that Figure 1 As shown, the specific structure and composition of the closure component 4 can be as follows: the closure component 4 includes a fixing ring 41 that fits and surrounds the outer periphery of the water outlet pipe 3 (as shown in the figure, the inner ring end is completely fitted at the outer periphery of the water outlet pipe 3, and there is a distance between the inner ring end and the water outlet end surface of the water outlet pipe 3);
[0028] The end of the fixed ring 41 facing the outlet pipe 3 is attached with a corrosion-resistant cushion layer 42 (the corrosion-resistant cushion layer 42 can be made of rubber or other materials);
[0029] The outlet pipe end of the outlet pipe 3 is threadedly connected with a pipe cover 43 and fits the corrosion-resistant cushion layer 42 to seal the outlet pipe end of the outlet pipe 3. The pipe cover 43 is threadedly connected to the outlet pipe 3 for fixing, contacts the corrosion-resistant cushion layer 42 for compression, seals the pipe cover 43 and the fixing ring 41, and then seals the outlet pipe 3.
[0030] The outer sides of the fixing ring 41 and the pipe cover 43 are fixedly provided with an anti-corrosion component 2 to provide an overall anti-corrosion setting and improve the protection effect.
[0031] The edges of the fixed ring 41 and the water outlet pipe 3 are transitionally connected by a fixed anti-corrosion component 2 (as shown in the figure, that is, the position where the inner ring end of the fixed ring 41 and the outer end of the water outlet pipe 3 are connected is attached with the anti-corrosion component 2 to further strengthen and improve durability).
[0032] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
