Description

Technical Field

[0001] This utility model relates to the field of flange fittings, and in particular to a flange fitting. Background Technology

[0002] A flange ferrule is a ferrule with a flange attached, which allows the ferrule to be quickly and stably installed on a pipeline.

[0003] Utility model patent CN212319076U discloses a novel compression fitting flange. Its key technical features include: a flange and a compression fitting; symmetrically and evenly spaced flange-flange connection threaded through holes oriented around the central axis of the flange between its left and right sidewalls; a protrusion on the side of the flange facing the compression fitting; and symmetrically and evenly spaced flange-compression fitting connection threaded blind holes oriented around the central axis of the flange on the sidewall connecting the flange and the compression fitting. The compression fitting includes a flange connecting ring connected to the flange and a pipe connecting ring at the end away from the flange. Both the flange connecting ring and the pipe connecting ring have compression fitting-pipe connection threaded through holes. This utility model enables a new process for connecting flanges to pipes via compression fittings without welding, greatly facilitating flange installation, maintenance, and replacement, and solving the technical challenge of connecting pipes when hot work is objectively impossible.

[0004] Regarding the above-mentioned issues, the inventors believe that the following technical defects exist: When the new type of ferrule flange is connected with screws, it is found that when the screws on the new type of ferrule flange are exposed to the air for a long time, the screw surface will undergo an oxidation reaction with the air. When the air humidity is high, the oxidation of the screw surface will be accelerated. The oxidized screw will significantly reduce the fixing effect on the flange, thereby affecting the stability of the screw fixing the flange.

[0005] Therefore, it is necessary to provide a new type of flange fitting to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where, when a new type of compression flange is connected with screws, the screws on the flange are exposed to air for a long time, causing oxidation on the screw surface. High humidity further accelerates this oxidation, significantly reducing the screws' effectiveness in securing the flange and thus affecting the stability of the screws in fixing the flange.

[0007] To solve the above-mentioned technical problems, this utility model provides a flange ferrule, comprising: a ferrule body, a flange body fixedly connected to one end of the arc surface of the ferrule body, an adjusting device provided on the arc surface of the flange body, the adjusting device including a fixing plate, the fixing plate being fixedly connected to the flange body, connecting blocks being fixedly connected to both ends of the arc surface of the fixing plate, a support block being fixedly connected to the side of the connecting block near the ferrule body, an adjusting sleeve being rotatably connected to the end of the support block away from the connecting block, a screw threadedly connected to the inner wall of the adjusting sleeve, a connecting rod being fixedly connected to the end of the screw away from the adjusting sleeve, and a sealing cover being fixedly connected to the end of the connecting rod away from the screw.

[0008] The aforementioned components achieve the following effect: by aligning the flange body on the ferrule with the flange body on the pipe, the two flange bodies can be connected by screws, thus installing the ferrule on the pipe. However, if the screws are exposed to air for a long time, the screw surface will undergo an oxidation reaction with the air. When the air humidity is high, the oxidation of the screw surface will be accelerated. The oxidized screw will significantly reduce its fixing effect on the flange body, thus affecting the stability of the screw fixing the two flanges. After connecting the two flange bodies with screws, the screw on the connecting rod is brought into contact with the adjusting sleeve. Rotating the adjusting sleeve will fix the screw and connecting rod inside the adjusting sleeve. After the connecting rod is fixed, the connecting rod will drive the sealing cover to be fixed on the surface of the screw. Thus, the sealing cover can seal the surface of the screw, effectively improving the service life of the screw and reducing the oxidation rate.

[0009] Preferably, the arc surface of the adjusting sleeve is fixedly connected to a plurality of connecting rods, and the ends of the plurality of connecting rods away from the adjusting sleeve are fixedly connected to the same connecting ring.

[0010] The effect achieved by the above components is that when rotating the connecting sleeve, the connecting ring installed on the connecting rod can be used to rotate the connecting sleeve, and using the connecting ring to rotate the connecting sleeve can increase the rotation speed of the connecting sleeve.

[0011] Preferably, a plurality of auxiliary blocks are fixedly connected to the side of the connecting ring away from the connecting rod, and the plurality of auxiliary blocks are evenly distributed on one side of the connecting ring.

[0012] The effect achieved by the above components is that when the adjusting sleeve is rotated by the connecting ring, the auxiliary block installed on the connecting ring can increase the friction between the worker's hand and the connecting ring, thereby increasing the speed at which the connecting sleeve is rotated by the connecting ring.

[0013] Preferably, sealing gaskets are fixedly connected to both ends of the two sealing covers that are close to each other.

[0014] The effect achieved by the above components is that when the sealing cover is used to protect the surface of the screws connected to the flange body from rust, the sealing gasket installed on the sealing cover can improve the tightness of the connection between the two sealing covers and improve the sealing effect of the sealing cover on the screws.

[0015] Preferably, the arc surface of the fixed plate is provided with an auxiliary device, which includes two fixing rings. The two fixing rings are respectively fixedly connected to both ends of the arc surface of the fixed plate. An adjusting rod is movably connected to the inner wall of the fixing ring. An adjusting block is slidably connected to the arc surface of the adjusting rod. An abutment plate is fixedly connected to the side of the adjusting block near the flange body. A spring is sleeved on the arc surface of the adjusting rod. Both ends of the spring are respectively fixedly connected to the adjusting block and the adjusting rod. A friction pad is fixedly connected to the side of the abutment plate near the flange body.

[0016] The effect achieved by the above components is as follows: After connecting the two flange bodies with screws, when it is necessary to fix the two flange bodies in place to prevent them from separating due to loose screws, first install the two flange bodies together with screws, press the adjusting block towards the spring, and the adjusting block will slide on the adjusting rod. The sliding of the adjusting block on the adjusting rod will drive the abutment plate and friction pad to move. Insert the adjusting rod into the fixing ring installed on the fixing plate, release the adjusting block, and the spring will drive the adjusting block to move on the adjusting rod, thereby driving the abutment plate and friction pad to abut against the bottom of one of the flange bodies. This allows the auxiliary device to compress the flange bodies and prevent the two flange bodies from separating when the screws loosen.

[0017] Preferably, a guide block is fixedly connected to one end of the adjusting rod near the fixed ring, and the cross-section of the guide block is arc-shaped.

[0018] The effect achieved by the above components is that when the adjusting rod is connected to the fixed ring, the guide block installed on the adjusting rod can increase the speed of connection between the adjusting rod and the fixed ring, and improve the efficiency of the connection between the two.

[0019] Preferably, the adjusting rod is a titanium alloy rod.

[0020] The effect achieved by the above components is that the adjustment rod made of titanium alloy has a relatively hard surface, and the surface of the adjustment rod is less likely to deform under long-term use, resulting in a longer service life.

[0021] Compared with related technologies, the flange ferrule provided by this utility model has the following beneficial effects:

[0022] This utility model provides a flange sleeve. By setting an adjustment device, after the flange is fixed with screws, the surface of the screws can be protected by the adjustment device. The protection of the adjustment device can effectively reduce the oxidation of the screw surface due to long-term contact with air, which would affect the fixing effect on the flange.

[0023] By setting up an auxiliary device, after connecting the two flanges with screws, the auxiliary device can be used to limit the movement of the two flanges. The auxiliary device can limit the angle of the flanges, which can effectively prevent the two flanges from becoming loose when the screws are loose. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1 to 6 The present invention provides a flange ferrule, comprising: a ferrule body 1, a flange body 4 fixedly connected to one end of the arc surface of the ferrule body 1, an adjustment device 2 provided on the arc surface of the flange body 4, and an auxiliary device 3 provided on the arc surface of the fixing plate 201.

[0034] In the embodiments of this utility model, please refer to Figures 2 to 4The adjusting device 2 includes a fixed plate 201, which is fixedly connected to the flange body 4. Connecting blocks 202 are fixedly connected to both ends of the arc surface of the fixed plate 201. A support block 203 is fixedly connected to the side of the connecting block 202 closest to the ferrule body 1. An adjusting sleeve 204 is rotatably connected to the end of the support block 203 away from the connecting block 202. A screw 205 is threadedly connected to the inner wall of the adjusting sleeve 204. A connecting rod 206 is fixedly connected to the end of the screw 205 away from the adjusting sleeve 204. A sealing cover 207 is fixedly connected to the end of the connecting rod 206 away from the screw 205. By aligning the flange body 4 on the ferrule body 1 with the flange body 4 on the pipe, the adjustment device can be adjusted. The screws connect the two flange bodies 4, allowing the ferrule body 1 to be installed on the pipe. However, prolonged exposure of the screws to air causes oxidation on their surface. High humidity accelerates this oxidation, significantly reducing the screws' effectiveness in securing the flange bodies 4 and affecting the stability of the fixation. After connecting the two flanges with screws, the threaded rod 205 on the connecting rod 206 is brought into contact with the adjusting sleeve 204. Rotating the adjusting sleeve 204 fixes the threaded rod 205 and the connecting rod 206 inside the adjusting sleeve 204. Once the connecting rod 206 is secured, The connecting rod 206 drives the sealing cover 207 to be fixed on the surface of the screw, thereby sealing the surface of the screw through the sealing cover 207, which can effectively improve the service life of the screw and reduce the oxidation rate. Several connecting rods 209 are fixedly connected to the arc surface of the adjusting sleeve 204. The ends of the connecting rods 209 away from the adjusting sleeve 204 are fixedly connected to the same connecting ring 210. When rotating the connecting sleeve, the connecting ring 210 installed on the connecting rod 209 can be used to rotate the connecting sleeve. Using the connecting ring 210 to rotate the connecting sleeve can increase the rotation speed of the connecting sleeve. Several connecting rods 209 are fixedly connected to the side of the connecting ring 210 away from the connecting rod 209. Several auxiliary blocks 211 are evenly distributed on one side of the connecting ring 210. When the adjusting sleeve 204 is rotated by the connecting ring 210, the auxiliary blocks 211 installed on the connecting ring 210 can increase the friction between the worker's hand and the connecting ring 210, and increase the speed at which the connecting sleeve is rotated by the connecting ring 210. Both ends of the two sealing covers 207 that are close to each other are fixedly connected with sealing gaskets 208. When the sealing covers 207 are used to protect the surface of the screws connected to the flange body 4 from rust, the sealing gaskets 208 installed on the sealing covers 207 can improve the tightness of the connection between the two sealing covers 207 and improve the sealing effect of the sealing covers 207 on the screws.

[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6The auxiliary device 3 includes two fixing rings 31, which are fixedly connected to the two ends of the arc surface of the fixing plate 201. An adjusting rod 32 is movably connected to the inner wall of the fixing ring 31. An adjusting block 33 is slidably connected to the arc surface of the adjusting rod 32. An abutment plate 35 is fixedly connected to the side of the adjusting block 33 near the flange body 4. A spring 34 is sleeved on the arc surface of the adjusting rod 32. The two ends of the spring 34 are fixedly connected to the adjusting block 33 and the adjusting rod 32, respectively. A friction pad 36 is fixedly connected to the side of the abutment plate 35 near the flange body 4. After the two flange bodies 4 are connected by screws, when it is necessary to fix the position of the two flange bodies 4 to prevent the two flange bodies 4 from detaching due to loose screws, first install the two flange bodies 4 together with screws, and press the adjusting block 33 towards the spring 34. The adjusting block 33 will slide on the adjusting rod 32, and the sliding of the adjusting block 33 on the adjusting rod 32 will drive the abutment plate. The adjusting rod 32 is inserted into the fixing ring 31 installed on the fixing plate 201, and the adjusting block 33 is released. The spring 34 drives the adjusting block 33 to move on the adjusting rod 32, thereby driving the abutment plate 35 and the friction pad 36 to abut against the bottom of one of the flange bodies 4. This allows the flange body 4 to be squeezed by the auxiliary device 3, preventing the two flange bodies 4 from separating when the screws are loose. A guide block 37 is fixedly connected to one end of the adjusting rod 32 near the fixing ring 31. The cross section of the guide block 37 is arc-shaped. When the adjusting rod 32 is connected to the fixing ring 31, the guide block 37 installed on the adjusting rod 32 can improve the speed of connection between the adjusting rod 32 and the fixing ring 31 and improve the efficiency of the connection. The adjusting rod 32 is a titanium alloy rod. The surface of the adjusting rod 32 is relatively hard. Under long-term use, the surface of the adjusting rod 32 is less likely to deform, resulting in a longer service life.

[0036] The working principle of the flange sleeve provided by this utility model is as follows: After connecting two flanges with screws, the screw 205 on the connecting rod 206 contacts the adjusting sleeve 204. Rotating the adjusting sleeve 204 fixes the screw 205 and the connecting rod 206 inside the adjusting sleeve 204. After the connecting rod 206 is fixed, it will drive the sealing cover 207 to be fixed on the surface of the screw. Thus, the sealing cover 207 can seal the surface of the screw, effectively improving the service life of the screw and reducing the oxidation rate. When rotating the connecting sleeve, the connecting rod 209 can be used to connect... The connecting sleeve is rotated using the connecting ring 210. Rotating the connecting sleeve using the connecting ring 210 increases the rotation speed of the connecting sleeve. When adjusting the sleeve 204 by rotating the connecting ring 210, the auxiliary block 211 installed on the connecting ring 210 increases the friction between the worker's hand and the connecting ring 210, thereby increasing the rotation speed of the connecting sleeve using the connecting ring 210. When the sealing cover 207 is used to protect the surface of the screws connected to the flange body 4 from rust, the sealing gasket 208 installed on the sealing cover 207 increases the tightness of the connection between the two sealing covers 207, thereby improving the sealing effect of the sealing cover 207 on the screws.

[0037] When it is necessary to fix the positions of the two flange bodies 4, first install the two flange bodies 4 together with screws, press the adjusting block 33 towards the spring 34, and the adjusting block 33 will slide on the adjusting rod 32. The sliding of the adjusting block 33 on the adjusting rod 32 will drive the abutment plate 35 and the friction pad 36 to move. Insert the adjusting rod 32 into the fixing ring 31 installed on the fixing plate 201, release the adjusting block 33, and the spring 34 will drive the adjusting block 33 to move on the adjusting rod 32, thereby driving the abutment plate 35 and the friction pad. 36 abuts against the bottom of one of the flange bodies 4, thereby enabling the auxiliary device 3 to press the flange body 4, preventing the two flange bodies 4 from separating when the screws loosen. When the adjusting rod 32 is connected to the fixing ring 31, the guide block 37 installed on the adjusting rod 32 can improve the connection speed between the adjusting rod 32 and the fixing ring 31, and improve the connection efficiency. The adjusting rod 32 is made of titanium alloy, and its surface is relatively hard. Under long-term use, the surface of the adjusting rod 32 is also less prone to deformation, resulting in a long service life.
