Description

Technical Field

[0001] This utility model relates to the field of bridge bend technology, and in particular to a full-diameter large-flow bridge bend. Background Technology

[0002] Full-bore high-flow-through bridge bends are specially optimized pipe connection fittings, mainly used at the intersection of fluid pipes in cold and hot water systems. Through innovative design, they ensure that the inner diameter of the pipes is consistent without any reduction (i.e., "full bore"), while maximizing fluid flow and reducing resistance, thereby improving system efficiency.

[0003] Currently, when using bridge bends, the bending part of the bridge bend is usually directly attached to the surface of the external pipe. This makes it impossible to fix the fit of the bridge bend, resulting in the bending part of the bridge bend being subjected to greater fluid impact force, which can easily cause damage.

[0004] Meanwhile, when the inlet and outlet of the bridge bend are connected to the external pipes, they are usually connected by a fitting method, which makes the connection of the bridge bend prone to loosening, resulting in water leakage inside the bridge bend.

[0005] Therefore, we propose a full-bore large-flow method for passing through bridge bends to address the problems mentioned above. Utility Model Content

[0006] This invention proposes a method for large-volume flow through a bridge bend with full diameter to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: including a bending body, a first fixing mechanism, a second fixing mechanism, and a bonding mechanism. The bonding mechanism includes a rubber block and a clamping ring. The upper surface of the clamping ring is connected to the lower surface of the rubber block. The rubber block and the clamping ring are used to improve the bonding effect between the bending body and other pipe surfaces, effectively providing support.

[0008] The first fixing mechanism includes a threaded rod, and the second fixing mechanism includes a rubber rod. The rubber rod is located to the right of the threaded rod. The threaded rod and the rubber rod are used to improve the tightness of the bridge bend connection and prevent leakage.

[0009] Preferably, the bonding mechanism further includes a horizontal plate, the lower surface of which is fixedly connected to the upper surface of the curved body, a push rod is slidably connected inside the horizontal plate, a bonding ring is fixedly connected to the bottom end of the push rod, and the lower surface of the bonding ring is connected to the upper surface of the rubber block, and an anti-slip pad is provided on the side surface of the clamping ring.

[0010] Preferably, the first fixing mechanism further includes a rubber pad, the upper surface of which is connected to the bottom end of the threaded rod, and a cover plate is fitted onto the outer surface of the threaded rod.

[0011] Preferably, the second fixing mechanism further includes a counterweight block, which is slidably connected to the inside of the cover plate. A connecting plate is fixedly connected to the side surface of the counterweight block, and the inside of the connecting plate is threadedly connected to the threaded rod.

[0012] Preferably, a water inlet pipe is fixedly connected to the right end of the bend, and a water outlet pipe is fixedly connected to the left end of the bend. The upper surfaces of the water inlet pipe and the water outlet pipe are both fixedly connected to the lower surface of the cover plate, and the bottom end of the threaded rod extends into the interior of the water inlet pipe and the water outlet pipe, respectively.

[0013] Preferably, the lower surface of the cross plate is provided with a rubber sleeve, and the inside of the rubber sleeve is in contact with the outer surface of the push rod.

[0014] Preferably, a fixing plate is fixedly connected to the inner wall of the curved body, a bending rod is fixedly connected to the front surface of the fixing plate, and a movable tube is sleeved on the outer surface of the bending rod, with the diameter of the movable tube being larger than that of the bending rod.

[0015] Preferably, the inner wall of the movable tube is connected to an elastic band, and the side surface of the elastic band is connected to the outer surface of the bending rod.

[0016] Preferably, both ends of the movable tube are provided with rubber tubes, and the upper and lower surfaces of the movable tube are provided with ribbons.

[0017] Preferably, a stop block is fixedly connected to the top of the push rod, the fitting ring is located at the front and rear of the bend, and the rubber rod is located on the right side of the inlet pipe and the left side of the outlet pipe, respectively.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, the push rod is moved downward, which drives the fitting ring, rubber block and clamping ring to move downward together. Utilizing the elasticity of the rubber block itself, the diameter of the clamping ring can be changed. The clamping ring located at the front and rear of the bend moves downward, and finally the anti-slip pad on its side surface is pressed and adhered to the surface of the pipe. The anti-slip pad plays a role in preventing slippage, increasing friction and protecting the pipe wall, thereby improving the fit of the bend. At the same time, it can support the bending part of the bridge bend and prevent damage to the bridge bend.

[0020] 2. In this utility model, the counterweight is moved downward, causing the rubber rod to bend under the influence of compression and rub against the surface of the pipe. When the rubber rod rubs against the surface of the pipe, the threaded rod is turned to fix the height of the counterweight. At the same time, the rotation of the threaded rod can drive the rubber pad to move together and rub against the surface of the pipe. In conjunction with the rubber rod, the tightness of the connection between the water inlet pipe, water outlet pipe and external pipe can be improved, and leakage can be prevented from occurring at the bridge bend.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1, as shown in the attached document Figure 1 - Figure 3As shown, it includes a bend 1, a first fixing mechanism 3, a second fixing mechanism 7, and a bonding mechanism 2. The bonding mechanism 2 includes a rubber block 205 and a clamping ring 202. The upper surface of the clamping ring 202 is connected to the lower surface of the rubber block 205. The rubber block 205 and the clamping ring 202 are used to improve the bonding effect of the bend 1 with other pipe surfaces and effectively provide support.

[0030] The first fixing mechanism 3 includes a threaded rod 303, and the second fixing mechanism 7 includes a rubber rod 703. The rubber rod 703 is located to the right of the threaded rod 303. The threaded rod 303 and the rubber rod 703 are used to improve the tightness of the bridge bend connection and prevent leakage.

[0031] The effect achieved by the entire embodiment 1 is as follows: by utilizing the elasticity of the rubber block 205, the angle of the clamping ring 202 can be expanded outward, thereby clamping it on the surface of the outer pipe body to fit and support the bending part of the bridge bend. At the same time, by utilizing the compression of the threaded rod 303 and the friction of the surface of the rubber rod 703, the sealing performance of the bridge bend and the pipe body can be improved, preventing water leakage from the bridge bend.

[0032] Example 2, as Figure 1 - Figure 2 As shown, the bonding mechanism 2 also includes a horizontal plate 201. The lower surface of the horizontal plate 201 is fixedly connected to the upper surface of the curved body 1. A push rod 203 is slidably connected inside the horizontal plate 201. A bonding ring 204 is fixedly connected to the bottom end of the push rod 203, and the lower surface of the bonding ring 204 is connected to the upper surface of the rubber block 205. An anti-slip pad 206 is provided on the side surface of the clamping ring 202. A stop block is fixedly connected to the top end of the push rod 203. The bonding ring 204 is located in front of and behind the curved body 1. A rubber sleeve 6 is provided on the lower surface of the horizontal plate 201, and the inside of the rubber sleeve 6 is bonded to the outer surface of the push rod 203.

[0033] The effect achieved by the entire embodiment 2 is as follows: when the lower surface of the bend 1 is in contact with the surface of the external pipe, the push rod 203 is moved downward by sliding the push rod 203 and the horizontal plate 201. The push rod 203 can drive the fitting ring 204, the rubber block 205 and the clamping ring 202 to move downward together. By utilizing the elasticity of the rubber block 205, the diameter of the clamping ring 202 can be changed. The clamping ring 202 located in front of and behind the bend 1 moves downward. Finally, the anti-slip pad 206 on its side surface is pressed and adhered to the surface of the pipe. The anti-slip pad 206 plays the role of preventing slippage, increasing friction and protecting the pipe wall, thereby improving the fit of the bend 1. At the same time, it can support the bending part of the bridge bend and prevent damage to the bridge bend.

[0034] Example 3, as Figure 1 and Figure 3The first fixing mechanism 3 also includes a rubber pad 302, the upper surface of which is connected to the bottom end of the threaded rod 303. A cover plate 301 is fitted on the outer surface of the threaded rod 303. The second fixing mechanism 7 also includes a counterweight 701, which is slidably connected to the inside of the cover plate 301. A connecting plate 702 is fixedly connected to the side surface of the counterweight 701, and the inside of the connecting plate 702 is threadedly connected to the threaded rod 303. A water inlet pipe 5 is fixedly connected to the right end of the bent body 1, and a water outlet pipe 4 is fixedly connected to the left end of the bent body 1. The upper surfaces of the water inlet pipe 5 and the water outlet pipe 4 are both fixedly connected to the lower surface of the cover plate 301. The bottom end of the threaded rod 303 extends into the inside of the water inlet pipe 5 and the water outlet pipe 4, respectively. The rubber rod 703 is located on the right side of the water inlet pipe 5 and the left side of the water outlet pipe 4, respectively.

[0035] The overall effect of embodiment 3 is as follows: external pipes can be connected to the inlet pipe 5 and outlet pipe 4. After the pipes are connected to the inlet pipe 5 and outlet pipe 4, the counterweight 701 is moved downwards, so that the rubber rod 703 is squeezed and can bend and rub against the surface of the pipe. When the rubber rod 703 rubs against the surface of the pipe, the threaded rod 303 is turned to fix the height of the counterweight 701. At the same time, the rotation of the threaded rod 303 can drive the rubber pad 302 to move together and squeeze against the surface of the pipe. With the rubber rod 703, the tightness of the connection between the inlet pipe 5, outlet pipe 4 and the external pipe can be improved, and leakage and other phenomena such as bridge bends can be prevented.

[0036] Example 4, as Figure 1 , Figure 4 and Figure 5 As shown, a fixed plate 13 is fixedly connected to the inner wall of the curved body 1. A bending rod 12 is fixedly connected to the front surface of the fixed plate 13. A movable tube 10 is sleeved on the outer surface of the bending rod 12, and the diameter of the movable tube 10 is larger than that of the bending rod 12. An elastic band 11 is connected to the inner wall of the movable tube 10, and the side surface of the elastic band 11 is connected to the outer surface of the bending rod 12. Rubber tubes 9 are provided at both ends of the movable tube 10, and ribbons 8 are provided on the upper and lower surfaces of the movable tube 10.

[0037] The effect achieved by the entire embodiment 4 is as follows: When the external water pipe enters the interior of the bend 1, the movable pipe 10 and the bending rod 12 are sleeved together, so that the movable pipe 10 can slide on the surface of the bending rod 12 under the influence of water pressure. Due to the connection between the inner wall of the movable pipe 10 and the elastic band 11, when the movable pipe 10 slides on the surface of the bending rod 12, the movable pipe 10 can pull the elastic band 11, and the movable pipe 10 can squeeze the rubber tube 9, so that the rubber tube 9 can be bent. The elasticity of the rubber tube 9 and the elastic band 11 allows the movable pipe 10 to move back and forth on the surface of the bending rod 12. The position of the ribbon 8 can be adjusted according to the movement of the movable pipe 10. The ribbon 8 can be used to clean the inner wall of the bend 1, thereby preventing the bridge bend from becoming blocked.

[0038] The working principle of the entire device is as follows: It can be connected to the inlet pipe 5 and the outlet pipe 4 through an external pipe. After the pipe is connected to the inlet pipe 5 and the outlet pipe 4, the counterweight 701 is moved downward, so that the rubber rod 703 can bend under the influence of compression and rub against the surface of the pipe. When the rubber rod 703 rubs against the surface of the pipe, the threaded rod 303 is turned to fix the height of the counterweight 701. At the same time, the rotation of the threaded rod 303 can drive the rubber pad 302 to move together and rub against the surface of the pipe.

[0039] Move the push rod 203 downwards so that the push rod 203 can drive the fitting ring 204, the rubber block 205 and the clamping ring 202 to move downwards together. Utilize the elasticity of the rubber block 205 itself so that the diameter of the clamping ring 202 can be changed. The clamping ring 202 located in front of and behind the bend 1 moves downwards, and finally the anti-slip pad 206 on its side surface is pressed and adhered to the surface of the pipe. The anti-slip pad 206 plays the role of preventing slippage, increasing friction and protecting the pipe wall.

[0040] By using the sleeve of the movable tube 10 and the bending rod 12, the movable tube 10 can slide on the surface of the bending rod 12 under the influence of water pressure. Due to the connection between the inner wall of the movable tube 10 and the elastic band 11, when the movable tube 10 slides on the surface of the bending rod 12, the movable tube 10 can pull the elastic band 11, and the movable tube 10 can squeeze the rubber tube 9, causing the rubber tube 9 to bend. Utilizing the elasticity of the rubber tube 9 and the elastic band 11, the movable tube 10 can move back and forth on the surface of the bending rod 12. The position of the ribbon 8 can be adjusted according to the movement of the movable tube 10, and the ribbon 8 can be used to clean the inner wall of the bending body 1.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
