Description

Technical Field

[0001] This utility model relates to the field of connecting elbow technology, specifically a connecting elbow that can resist liquid impact. Background Technology

[0002] Elbows are a common type of pipe fitting used in plumbing installations, connecting pipes at bends to change their direction. When fluid passes through an elbow, its direction changes, resulting in a greater impact force at the elbow. Liquids exert a greater impact on elbows than gases, and over time, elbows are prone to deformation. A search revealed a patent with publication number CN219933309U that discloses an impact-resistant elbow. By incorporating a buffer assembly, when water flows from above to the inlet pipe fitting, the impact force of the water flow strikes the buffer blades, causing three sets of buffer blades to rotate around a pivot axis, thus mitigating the impact of the water flow on the bent pipe fitting. An impact protection plate is installed at the bend in the middle. To effectively prevent corrosive water or gas from impacting and corroding the elbow wall, a protective plate and compression spring are installed at the bend to buffer the impact of water flow, dispersing the impact force and ensuring the service life of the elbow. However, while the spring and impact protective plate in the middle can buffer most of the water flow, some water still enters through the gap between the impact protective plate and the inner wall of the elbow, impacting the inner wall. Its impact resistance needs to be improved. Therefore, a liquid-resistant connecting elbow is designed to facilitate the flow of liquid close to the inner wall of the elbow, diverting the impact, reducing the impact on the elbow, ensuring the flow rate, and improving the liquid impact resistance. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a connection elbow that is resistant to liquid impact. This facilitates the diversion of liquid flowing through the elbow by directing it close to the inner wall of the elbow, thus diverting the impact, reducing the impact on the elbow, ensuring flow velocity, and improving resistance to liquid impact.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connecting elbow resistant to liquid impact, comprising an elbow body, wherein the interior of the elbow body is a through channel and a guide channel surrounding the outside of the through channel, and a guide ribbon fixedly installed on the inner wall of the elbow body is provided at the guide channel, wherein the ratio of the guide width of the guide channel to the through width of the through channel is less than 1:3, a reinforcing mechanism is also provided on the exterior of the elbow body, and a connecting mechanism is provided at both ends of the elbow body.

[0007] Preferably, the reinforcing mechanism includes a reinforcing ring fixedly installed around the outer side of the middle part of the elbow body, and support ribs along the flow direction of the elbow body are fixedly installed on both sides of the reinforcing ring.

[0008] Preferably, the connecting mechanism includes a connecting flange fixedly installed at the end of the elbow body, and the connecting flange has a plurality of connecting holes circumferentially.

[0009] Preferably, a sealing gasket ring is embedded in the end of the connecting flange.

[0010] Preferably, a second sealing gasket is embedded in the connecting flange at the position between the multiple connecting holes, and the second sealing gasket protrudes from the end face of the connecting flange in its free state.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, this utility model provides a connection elbow that can resist liquid impact, and has the following beneficial effects:

[0013] This liquid-impact resistant connecting elbow divides the interior of the elbow body into a through channel and a guide channel surrounding the through channel. The guide ribbon within the guide channel diverts liquid close to the inner wall of the elbow body, reducing the impact force on the outer center of the elbow. Since the ratio of the guide channel width to the through channel width is less than 1:3, the through channel ensures normal liquid flow, maintaining normal flow velocity while reducing impact on the outer center of the elbow. A reinforcing mechanism enhances the overall strength of the elbow body, and the connecting mechanisms on both sides facilitate connection between the elbow body and other pipe fittings. This liquid-impact resistant connecting elbow effectively diverts liquid close to the inner wall of the elbow, reducing impact and ensuring flow velocity while improving resistance to liquid impact.

[0021] Please see Figure 1-4 A connection elbow resistant to liquid impact includes an elbow body 1. The elbow body 1 has an internal through channel and a flow guide channel surrounding the outside of the through channel. A flow guide ribbon 2 is fixedly installed on the inner wall of the elbow body 1 at the flow guide channel. The ratio of the flow guide width of the flow guide channel to the through width of the through channel is less than 1:3. A reinforcing mechanism is also provided on the outside of the elbow body 1. A connecting mechanism is provided at both ends of the elbow body 1.

Support ribs 4 along the flow direction of the elbow body 1 are fixedly installed on both sides of the reinforcing ring 3. By setting the reinforcing ring 3, the impact resistance of the middle part of the elbow body 1 is increased. By setting multiple support ribs 4, the overall structural stability of the elbow body 1 is improved, and the impact resistance is further improved.

[0023] Specifically, the connection mechanism includes a connecting flange 5 fixedly installed at the end of the elbow body 1. The connecting flange 5 has multiple connecting holes in the circumferential direction. The connection flange 5 facilitates the connection of the elbow body 1 into the conveying pipeline.
