Description

Technical Field

[0001] This utility model belongs to the field of flange technology and relates to a novel connecting flange. Background Technology

[0002] A flange is a component used to connect pipes to each other. It is attached to the pipe end and has holes. Bolts are used to tightly connect two flanges, and a gasket is used to seal between the flanges. A flange is a disc-shaped component and is most commonly used in pipeline engineering. Flanges are always used in pairs. In pipeline engineering, flanges are mainly used for connecting pipes. At the ends where two pipes need to be connected, a flange is installed on each side. Low-pressure pipelines can use threaded flanges. A gasket is placed between the two flanges, and then they are tightened with bolts.

[0003] There are many types of flanges, such as the common slip-on flanges and threaded flanges. Slip-on flanges can be directly connected to pipes by welding, while threaded flanges are connected to pipes by directly threading the threaded end of the pipe into the threaded hole in the center of the flange. This connection method is efficient and quick, but because it uses a single thread for connection, its sealing performance is poor. After long-term use, the thread may loosen and leak easily. Summary of the Invention

[0004] The purpose of this utility model is to provide a novel connecting flange to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: A novel connecting flange includes an outer disc body, an inner disc body, an outer pressure sleeve, and a pipe. The inner disc body is fixedly installed inside the outer disc body, and the inner disc body and the outer disc body are integrally formed. An internal threaded connection groove is provided in the middle of the inner disc body. A sealing platform is provided at one end of the internal threaded connection groove. An inner rubber strip is provided on the surface of the sealing platform. Side grooves are provided on both sides of the inner disc body. A clamping arm is movably connected inside the side groove. A locking rod is threadedly connected to one end of the clamping arm.

[0006] In the aforementioned novel connecting flange, an outer pressure sleeve is installed on the outer side of the inner disc, and one end of the outer pressure sleeve is connected to a pipe.

[0007] In the aforementioned novel connecting flange, one end of the outer pressure sleeve is provided with an internal threaded connector, and the internal threaded connector is threaded into the interior of the internal threaded connection groove.

[0008] In the aforementioned novel connecting flange, a sealing seat is provided between the internal threaded connector and the external pressure sleeve, and the sealing seat is pressed tightly inside the sealing platform.

[0009] In the aforementioned novel connecting flange, locking and limiting holes are provided on both sides of the surface of the outer pressure sleeve, and one end of the locking rod is threaded into the inside of the locking and limiting hole.

[0010] In the aforementioned novel connecting flange, multiple fixing holes are evenly arranged at the edge of the outer disc body, an outer rubber strip is provided on the surface of the inner disc body, and the outer pressure sleeve is pressed against the outside of the outer rubber strip.

[0011] Compared with the prior art, the advantages of this novel connecting flange are as follows:

[0012] This application provides an internal threaded connection groove inside the inner disc body that connects to an internal threaded connector at one end of the pipe. Simultaneously, a sealing platform and an inner rubber strip are provided at the front end of the internal threaded connection groove. These, along with an outer rubber strip on the outer surface of the inner disc body, ensure that the sealing pressure seat at one end of the pipe is pressed against the sealing platform during pipe connection. The inner and outer rubber strips enhance the sealing performance of the entire pipe connection. Simultaneously, the outer pressure sleeve at one end of the pipe can be pressed against the outside of the inner disc body. Rotating the clamping arms on both sides of the inner disc body presses the clamping arms against the sides of the outer pressure sleeve. Rotating the locking rod locks the outer pressure sleeve in place. The outer pressure sleeve protects the interior of the inner disc body and prevents the internal threaded connector from slipping off after prolonged use. Attached Figure Description

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] A novel connecting flange includes an outer flange 1, an inner flange 2, an outer pressure sleeve 11, and a pipe 12. The inner flange 2 is fixedly installed inside the outer flange 1, and the inner flange 2 and the outer flange 1 are integrally formed. The inner flange 2 has an internal threaded connection groove 7 in the middle. One end of the internal threaded connection groove 7 is provided with a sealing surface 8. The surface of the sealing surface 8 is provided with an inner rubber strip 9. Side grooves 4 are opened on both sides of the inner flange 2. A clamping arm 5 is movably connected inside the side groove 4. One end of the clamping arm 5 is threadedly connected with a locking rod 6.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses a novel connecting flange. Specifically, an outer pressure sleeve 11 is installed on the outer side of the inner disc body 2. One end of the outer pressure sleeve 11 is connected to a pipe 12. The outer pressure sleeve 11 is made of metal and is mainly pressed on the outer side of the inner disc body 2 to cover the inner disc body 2.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses a novel connecting flange. Specifically, one end of the outer pressure sleeve 11 is provided with an internal thread connector 13, and the internal thread connector 13 is threaded into the internal thread connection groove 7. Both the internal thread connector 13 and the internal thread connection groove 7 are existing publicly disclosed structures. Through the threaded connection, the pipe 12 and the flange can be directly installed.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses a novel connecting flange. Specifically, a sealing pressure seat 14 is provided between the internal threaded connector 13 and the external pressure sleeve 11. The sealing pressure seat 14 is pressed into the sealing platform 8 and is a metal ring.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses a novel connecting flange.

After being connected to the designated position, the sealing pressure seat 14 at one end of the pipe 12 can be pressed against the sealing platform 8 for sealing support. Since the sealing platform 8 and the inner rubber strip 9 on the sealing platform 8 are set at the front end of the internal threaded connection groove 7, and the outer rubber strip 10 on the outer surface of the inner disc 2 cooperate, the sealing performance of the entire pipe 12 and flange connection is improved by the inner rubber strip 9 and the outer rubber strip 10. At the same time, the outer pressure sleeve 11 at one end of the pipe 12 can be pressed against the outside of the inner disc 2. Then, the clamping arms 5 on both sides of the inner disc 2 are rotated so that the clamping arms 5 are pressed against the side of the outer pressure sleeve 11. The locking rod 6 is rotated so that the locking rod 6 locks the outer pressure sleeve 11. The outer pressure sleeve 11 can protect the inside of the inner disc 2 and also prevent the internal threaded connector 13 from slipping off during long-term use.
