Description

Technical Field

[0001] This utility model relates to the field of pipe sealing joint technology, and in particular to a quick-sealing joint for pipe connections. Background Technology

[0002] Quick-sealing joints for pipe connections are components used in the process of pipe connection to enable quick connection between pipes or between pipes and external equipment while ensuring sealing performance. They are widely used in water supply and drainage, gas transmission, industrial fluid transmission and other fields. Their core function is to simplify pipe connection operations and prevent fluid leakage from the joint during transmission, thus ensuring the stable operation of the pipeline system.

[0003] Existing pipe connection sealing joints have obvious defects. Most joints rely on only a single sealing structure, such as sealing rings or threads, with few sealing layers. When the fluid pressure inside the pipe changes or after long-term use, the sealing performance is prone to decline, and leakage problems are very likely to occur. Some joints are not tight enough to secure the pipe. Under pipe vibration, fluid impact or external force pulling, the joint is prone to slipping off the pipe end, resulting in connection failure. Therefore, this application provides a quick-sealing joint for pipe connections to meet the requirements. Utility Model Content

[0004] The purpose of this invention is to provide a quick-sealing connector for pipe connections to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A quick-sealing connector for pipe connection includes a connector, with a first cap and a second cap threaded to both ends of the connector, a sealing sleeve installed inside the connector and near the first cap, a fastening sleeve sleeved on the outside of the sealing sleeve, and a clamping sleeve inserted into the connector away from the first cap, the outer wall of the clamping sleeve contacting the inner wall of the second cap.

[0007] Optionally, the connector has a bearing portion inside, and the sealing sleeve has a boss portion on the outside, with the boss portion abutting against one side of the bearing portion.

[0008] Optionally, the fastening cylinder is composed of a cylinder body and fins, with the fins fixed at equal intervals at one end of the cylinder body.

[0009] Optionally, the inner wall of the first cap is provided with an arc portion, and the arc portion contacts the end of the fin.

[0010] Optionally, the clamping cylinder is composed of a ring body and a conical cylinder, and the inner wall of the connector at the end away from the first cap is provided with an outwardly expanding portion that cooperates with the conical cylinder.

[0011] Optionally, an extension tube is fixedly connected to one end of the second cap away from the connector, and a connecting flange is fixedly connected to one end of the extension tube.

[0012] Optionally, nuts are fixedly connected to the outer sides of the connector, the first cap, and the second cap.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects:

[0014] In the above-mentioned solution, the quick-sealing connector for pipe connection provided in this application forms a primary seal by means of a first cap, a fastening cylinder, and a sealing liner. When the first cap is tightened, the arc-shaped part of its inner wall squeezes the fins of the fastening cylinder, causing the fins to deform inward and press the sealing liner tightly against the outer wall of the pipe. At the same time, the second cap, in conjunction with the clamping cylinder, forms a secondary seal. Tightening the second cap causes the clamping cylinder to slide. The conical part of the clamping cylinder and the outward expansion part of the inner wall of the connector work together to reinforce the pipe. The secondary sealing structure effectively solves the problem of easy leakage of a single seal and significantly improves the reliability of the seal.

[0015] In the primary seal, the compression of the sealing liner by the deformed fins, and the cooperation between the clamping sleeve and the outer expansion of the connector in the secondary seal, not only achieve a seal, but also form a bidirectional fastening for the pipeline, preventing the connector from slipping off the pipeline end due to pipeline vibration, fluid impact, etc., and ensuring connection stability.

[0030] like Figures 1 to 5As shown, this embodiment of the present invention provides a quick-sealing connector for pipe connections, including a connector 1. A first cap 2 and a second cap 3 are threaded to both ends of the connector 1, respectively. An extension pipe is fixedly connected to the end of the second cap 3 furthest from the connector 1, and a connecting flange 4 is fixedly connected to one end of the extension pipe. Nuts are fixedly connected to the outer sides of the connector 1, the first cap 2, and the second cap 3. The connecting flange 4 facilitates connection of the connector to external equipment or pipes. The nuts on the outer sides of the connector 1, the first cap 2, and the second cap 3 facilitate installation. For the fastening operation, a sealing sleeve 5 is installed inside the connector 1 and near the end of the first cap 2. A bearing portion is provided inside the connector 1, and a boss portion 501 is provided on the outer side of the sealing sleeve 5. The boss portion 501 abuts against one side of the bearing portion. A fastening sleeve 6 is sleeved on the outer side of the sealing sleeve 5. The fastening sleeve 6 consists of a cylinder 601 and fins 602. The fins 602 are equidistantly fixed at one end of the cylinder 601. The inner wall of the first cap 2 has an arc portion, which contacts the end of the fins 602. The abutment of the boss portion 501 can secure the sealing sleeve 5. Positioning is achieved to prevent sliding within the connector 1. Tightening the first cap 2 compresses the arc-shaped portion against the fin 602, causing it to deform inwards. This, in turn, compresses and secures the sealing sleeve 5 to the outer wall of the pipe, achieving a primary seal. A clamping sleeve 7 is inserted into the end of the connector 1 furthest from the first cap 2. The outer wall of the clamping sleeve 7 contacts the inner wall of the second cap 3. The clamping sleeve 7 consists of a ring portion 701 and a conical portion 702. The inner wall of the connector 1 furthest from the first cap 2 has an outwardly expanding portion that mates with the conical portion 702. Tightening... The second cap 3 can drive the clamping cylinder 7 to slide outside the pipe, thereby allowing the ring part 701 to be inserted into the interior of the connector 1. It is worth mentioning that since the inner wall of the connector 1 is provided with an outwardly flared part with an inclined cross-section, it can cooperate with the cone part 702 to reinforce the pipe and achieve a secondary seal. By using the first cap 2 in conjunction with the fastening cylinder 6 and the sealing liner 5, and the second cap 3 in conjunction with the clamping cylinder 7, a secondary seal can be achieved on the pipe to improve the sealing effect of the pipe and also to tighten the pipe, preventing the joint from slipping off the end of the straight pipe.

[0031] The working principle of this utility model:

[0032] First, insert the sealing sleeve 5 into the connector 1, ensuring that the protrusion 501 on the outer side of the sealing sleeve 5 abuts against the bearing portion inside the connector 1. This positions the sealing sleeve 5 and prevents it from sliding inside the connector 1. Next, place the first cap 2 and the fastening sleeve 6 onto the outer side of the pipe to be connected. Then, insert the connector 1 and the sealing sleeve 5 onto the outside of the pipe, and insert the fastening sleeve 6 into the inside of the sealing sleeve 5. Using the nuts on the outer sides of the connector 1 and the first cap 2, tighten the first cap 2 with a tool. The first cap 2 moves towards the connector 1, and its inner arc gradually contacts and compresses the end of the fins 602 of the fastening sleeve 6. As the first cap 2 continues to tighten, the compressive force of the arc on the fins 602 increases, causing the fins 602 to deform inward. The deformed fins 602 push the sealing sleeve 5 tightly against the outside of the pipe. The pipe wall is first sealed to form a primary seal, initially preventing fluid leakage. The clamp cylinder 7 and the second cap 3 are placed on one end of the pipe. With the help of the nuts on the outside of the connector 1 and the second cap 3, the second cap 3 is tightened. The second cap 3 moves towards the connector 1. Since its inner wall is in contact with the outer wall of the clamp cylinder 7, it will drive the clamp cylinder 7 to slide from the outside of the pipe into the inside of the connector 1. The ring part 701 of the clamp cylinder 7 is gradually inserted into the inside of the connector 1. At the same time, the cone part 702 of the clamp cylinder 7 cooperates with the outward expansion part of the inner wall of the connector 1 away from the first cap 2. As the second cap 3 is continuously tightened, the cooperation force between the cone part 702 and the outward expansion part increases, further reinforcing the pipe and forming a secondary seal. Finally, through the synergistic effect of the primary and secondary seals, the efficient sealing and stable connection of the pipe are achieved, preventing the joint from slipping off the pipe end.
