Description

Technical Field

[0001] The utility model relates to the technical field of flange joints, in particular to a quick-insert and detachable flange joint. Background Art

[0002] Flange joints are widely used as connecting elements in piping systems. They connect two pipes or equipment together through flanges to achieve fluid transmission or equipment fixation. Currently, in order to make flange joints and pipe connections more efficient, quick-connect flange joints have been introduced on the market. They combine the stability of flange connections with the convenience of quick-connect connections, making them a highly efficient pipe connection method.

[0003] The existing quick-connect flange connector has multiple inverted teeth on the outer surface of one end of the quick-connect connector. Although the connector body with the inverted teeth structure can well prevent the hose from slipping out and has a certain sealing performance,

[0004] However, after a period of long-term use, especially when the pressure in the hose is high, the sealing performance of the connection between the quick-insert flange connector and the pipe will be affected to a certain extent, resulting in leakage at the connection. Utility Model Content

[0005] The purpose of the present utility model is to solve the problem that the sealing performance of the connection between the quick-insert flange joint and the pipeline will be affected to a certain extent after long-term use of the existing quick-insert flange joint mentioned in the above background technology, especially when the pressure in the hose is high, thereby causing leakage at the connection.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A quick-insert and detachable flange joint comprises a joint body, one end of which is provided with a flange head, the other end of which is provided with a connecting pipe body, the connecting pipe body is provided with a connector for quick connection with a pipeline, and the connector includes a sealing ring for improving the sealing performance of the joint.

The connector 1 and the connector 2 respectively cooperate with the limit rods at the corresponding positions. By providing two groups of limit rods, the sealing ring 1 and the sealing ring 2 can be staggered.

[0014] Preferably, the sealing ring 1 and the sealing ring 2 are rubber rings or silicone rings. When in use, they can be made of rubber or elastomer materials to ensure that the sealing ring 1 and the sealing ring 2 can be deformed outward after being squeezed.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The utility model provides a connecting piece so that the flange joint and the pipe can be effectively sealed after being plugged in. The sealing ring 1 and the sealing ring 2 on the connecting piece can be squeezed by the connecting head 2 and the connecting head 3 to tightly adhere to the inner wall of the pipe. The sealing ring 1 and the sealing ring 2 can better seal the pipe when the sealing effect of the inverted tooth structure is not good. Through multiple seals, the flange joint can be used for a longer time while maintaining a good seal. BRIEF DESCRIPTION OF THE DRAWINGS

Example

[0027] See also Figure 1-Figure 4 The 32nd and 33rd connectors are provided with a plurality of sealing rings, each of which is provided with a plurality of sealing rings, each of which is provided with a plurality of sealing rings, each of which is provided with a plurality of sealing rings, each of which is provided with a plurality of sealing rings, each of which is provided with a plurality of sealing rings, each of which is provided with a plurality of sealing rings, each of which is provided with a plurality of sealing rings, each of which is provided with a plurality of sealing rings,

[0028] Furthermore, connector 2 32 is above connector 1 31, connector 33 is above connector 2 32, and connector 33 3 is connected to a connecting ring 36 at one end away from connector 2 32. Connector 3 33 can be pushed downward by connecting ring 36, so that connector 3 33 and connector 2 32 can squeeze sealing ring 1 34 and sealing ring 2 35 respectively. Connector 3 33 is connected to connecting ring 36 at one end thereof, and connecting end 311 is rotatably connected to connecting ring 36. Through the rotating connection between connecting ring 36 and connecting end 311 on the connector, connecting ring 36 will not drive connector 3 33 to rotate together when rotating, but will only drive connector 3 33 to move linearly up and down.

[0029] Furthermore, a ring body 11 is provided around the connector body 1, and a connecting ring 36 is sleeved on the ring body 11 and is threadedly connected thereto. The connecting ring 36 is threadedly engaged with the ring body 11 so that the connecting ring 36 can move up and down when rotating. By moving the connecting ring 36 downward, the connector 2 32 and the connector 3 33 can also be pushed downward.

[0030] It should be noted that a limit rod 21 is provided on the connecting tube body 2, and a limit groove 37 is provided on the inner side of the connecting head 2 32 and the connecting head 3 33 for cooperating with the limit rod 21. Through the cooperation between the limit groove 37 and the limit rod 21, the connecting head 2 32 and the connecting head 3 33 can stably move linearly up and down. There are two groups of limit rods 21, which are respectively located on the upper and lower sides of the connecting tube body 2. The connecting head 1 31 and the connecting head 2 32 respectively cooperate with the limit rods 21 at the corresponding positions. By setting two groups of limit rods 21, the sealing ring 1 34 and the sealing ring 2 35 can be staggered.

[0031] It should be added that the sealing ring 1 34 and the sealing ring 2 35 are both made of a sealing material with good sealing performance when in use, and are rubber rings or silicone rings when in use, to ensure that the sealing ring 1 34 and the sealing ring 2 35 can be deformed outward after being squeezed.

[0032] When the present invention is in use, when the connector 3 is plugged into the pipe body, the pipe body is inserted into the outside of the connector 3, and one end of the pipe body is sealed and connected together through the inverted tooth structure on the connector head 2 32 and the connector head 33. At this time, the joint is quickly connected together by plugging with the pipe, and then the connecting ring 36 is rotated. The connecting ring 36 is connected by the threaded connection between the ring body 11, so that the connecting ring 36 can move when it is rotated. Move the connecting ring 36 downward, and the connecting ring 36 pushes the connector head 33 to move downward, and the connector head 33 By moving downward to squeeze the sealing ring 2 35, and as the connector 3 3 moves downward, the connector 2 32 is also pushed downward to be squeezed and moved. The connector 2 32 moves downward to squeeze the sealing ring 2 35. The sealing ring 1 34 and the sealing ring 2 35 are deformed outward after being squeezed, so that they can tightly rest against the inner wall of the connected pipe body to form a seal. When the inverted tooth structure of the flange joint cannot form a good seal after long-term use, the sealing ring 1 34 and the sealing ring 2 35 can further improve the sealing performance and effectively prevent leakage of the flange joint.

[0033] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
