Description

Technical Field

[0001] The utility model relates to the technical field of seamless elbows, in particular to a steel seamless elbow with an internal supporting structure. Background Art

[0002] In the piping system, elbows are pipe fittings that change the direction of the pipeline. The three most commonly used angles are 45°, 90° and 180°. In addition, other non-normal angle elbows such as 60° are also included according to project needs.

[0003] When the seamless elbow in the prior art is used under high pressure, the rapid water flow will continuously impact the elbow part, which may cause a certain vibration to the seamless elbow. Long-term use will cause the seamless elbow to loosen, thereby affecting the normal use of the seamless elbow. Most of the existing seamless elbows have no protective measures. During the use and installation process, the elbow may be affected to a certain extent due to collision, resulting in a decrease in the use effect and service life of the seamless elbow.

DETAILED DESCRIPTION

[0019] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0021] A seamless steel elbow with an internal support structure, comprising an elbow body 1, wherein one end of the elbow body 1 is provided with a water inlet 16, the other end of the elbow body 1 is provided with a water outlet 17, both ends of the elbow body 1 are provided with external threads 14 on the outside, a support frame 13 is installed in the middle of the inner wall of the elbow body 1, a protective tube 4 is sleeved around the elbow body 1, an insulation layer 7 matching the protective tube 4 is installed inside the protection tube 4, a slide groove 9 is provided on the inner wall of the insulation layer 7, and an upper support plate is slidably matched in the slide groove 9 11 and the lower support plate 12, a plurality of springs 10 are installed between the upper support plate 11, the lower support plate 12 and the inner wall of the slide groove 9, and the upper support plate 11, the lower support plate 12 and the support frame 13 are used to support and dampen the elbow part of the elbow body 1, reduce the impact force of the water flow on the elbow part, and ensure the normal use of the elbow body 1. The protective tube 4 is used to protect the elbow body 1 during installation and use, to avoid the impact of collision on the elbow body 1, and to increase the service life of the elbow body 1.

[0022] Furthermore: the inner surface of the elbow body 1 is coated with an anti-oxidation inner coating 5, the outer surface of the elbow body 1 is coated with an anti-oxidation outer coating 6, the thermal insulation layer 7 is a hard polyurethane foam plastic, and the upper support plate 11 and the lower support plate 12 are both arc-shaped. The anti-oxidation inner coating 5 and the anti-oxidation outer coating 6 can effectively prevent the elbow body 1 from being corroded, thereby increasing the service life of the elbow body 1. The thermal insulation layer 7 can reduce the loss of heat inside the elbow body 1, thereby increasing the thermal insulation effect of the elbow body 1.

[0023] Further: the outer side of the protection tube 4 is sleeved with a rubber tube sleeve 8, the two ends of the protection tube 4 are equipped with sealing pads 3, the two ends of the elbow body 1 are equipped with leakproof pads 2, the sealing pad 3 is circular, and the cross section of the sealing pad 3 is T-shaped, the leakproof pad 2 is circular, and the cross section of the leakproof pad 2 is U-shaped, and the two ends of the elbow body 1 are threadedly connected with a water pipe 15, one end of the water pipe 15 cooperates with the sealing pad 3, and the inner wall of the water pipe 15 cooperates with the leakproof pad 2. The leakproof pad 2 and the sealing pad 3 cooperate with each other, which effectively increases the elbow body 1 and the water The sealing at the connection of the pipe 15 prevents leakage of the elbow body 1 during use. One end of the water pipe 15 fits tightly with the sealing pad 3, and cooperates with the upper support plate 11 and the lower support plate 12. When the water flow hits the elbow part, the upper support plate 11 and the lower support plate 12 can reduce the shock of the elbow part of the elbow body 1, which can reduce the impact of the water flow on the elbow body 1. The rubber tube sleeve 8 can protect the protective tube 4 during use and installation, thereby protecting the elbow body 1 and avoiding the impact of collision on the elbow body 1.

[0024] Furthermore: the support frame 13 is set in a triangular shape, and the three top ends of the support frame 13 are welded to the inner wall of the elbow body 1, the support frame 13 is set with a double bevel on the side near the water inlet 16, and the support frame 13 is set in an arc shape on the side near the water outlet 17. The support frame 13 is made of alloy steel. The elbow part of the elbow body 1 can be supported by the support frame 13, and the water flow flowing into the water inlet 16 can be diverted by the double bevel on one side of the support frame 13. When the water flow pressure is high, the inner wall of the elbow body 1 can also be flushed, reducing the generation of scale inside the elbow body 1.

[0025] In actual use, first connect the external threads 14 at both ends of the elbow body 1 to the water pipe 15, so that one end of the water pipe 15 is in close contact with one side of the sealing gasket 3, and the water flow can flow into the elbow body 1 through the water inlet 16 and flow out of the elbow body 1 through the water outlet 17. During installation, the protective tube 4 can be protected by the rubber tube sleeve 8, thereby protecting the elbow body 1 and avoiding the impact of collision on the elbow body 1. During use, the anti-oxidation inner coating 5 and the anti-oxidation outer coating 6 can effectively prevent the elbow body 1 from being corroded, thereby increasing the service life of the elbow body 1. The heat preservation layer 7 can reduce the heat loss inside the elbow body 1 and increase the heat preservation effect of the elbow body 1. When the water flow pressure is large, the spring 10 and the upper support The plate 11 and the lower support plate 12 reduce the shock of the elbow body 1 and the vibration caused by the water flow impacting the elbow body 1. It should be noted that the water pipe 15 is tightly fitted with the sealing gasket 3 to make the water pipe 15 relatively fixed to the protective tube 4, thereby avoiding the phenomenon of loosening of the elbow body 1 due to impact and vibration. At this time, the double slopes of the support frame 13 are used to divert the water flow, thereby impacting the inside of the elbow body 1, reducing the generation of scale inside the elbow body 1, ensuring the fluidity inside the elbow body 1, and facilitating use. At the same time, the support frame 13 makes the internal structure of the elbow body 1 more stable, and makes the elbow part of the elbow body 1 less likely to deform, so that the elbow body 1 can withstand the passage of water with higher pressure, thereby increasing the scope of application of seamless elbows.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
