Description

Technical Field

[0001] This utility model relates to the field of compensator technology, specifically to a non-metallic soft corrugated compensator with a leak-proof structure. Background Technology

[0002] Expansion joints, also commonly called expansion joints or contraction joints, consist of a bellows (an elastic element) as its main working component, along with end pipes, supports, flanges, conduits, and other accessories. As a type of compensating element, it compensates for the thermal expansion of pipelines, thereby reducing stress on the pipe walls and forces acting on valves or support structures. Bellows compensators are a relatively new industrial product developed in recent years. They are elastic compensating elements that expand and contract freely with the system. They effectively and reliably compensate for temperature differences and displacements in pipelines transporting various fluids caused by factors such as the medium and environment, positional differences caused by equipment or buildings, and errors caused by engineering systems and equipment installation. They can also effectively balance pressure fluctuations in the system and have excellent effects on shock absorption, vibration reduction, vibration damping, and noise reduction.

[0003] The "S-type PP / PPH / PPS / PE connected flexible corrugated compensator" disclosed in application number "CN201821879253.0" is also an increasingly mature technology. It "includes two connecting flanges and an S-type flexible corrugated pipe fixed between the two connecting flanges. The S-type flexible corrugated pipe includes two outer fixed pipes, with multiple outer corrugated structures protruding outwards between the outer fixed pipes. The two outer fixed pipes are respectively welded and fixed to the two connecting flanges. The outer corrugated structure includes two mirror-arranged outer support walls and a top wall connected to the top of the two outer support walls." However, this compensator still has the following defects during use:

[0004] The compensator does not have a sealing structure when connected to an external flange. Therefore, when docking with an external flange, the gap between the flanges can cause liquid leakage. Utility Model Content

[0005] The purpose of this invention is to provide a non-metallic soft corrugated compensator with a leak-proof structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A non-metallic soft corrugated compensator with a leak-proof structure includes: a body, a first flange, a second flange, and a leak-proof mechanism. The first flange is fixedly connected to both ends of the body, the second flange is disposed on one side of the first flange, and the leak-proof mechanism is disposed inside the first and second flanges. The leak-proof mechanism includes a ring, a movable groove, an arc-shaped component, a mounting groove, and an arc-shaped sealing ring. The ring is fixedly connected to the inner wall of the first flange, the movable groove is located at the top of the ring, the arc-shaped component is disposed inside the movable groove, the mounting groove is located on the outer wall of the arc-shaped component, and the arc-shaped sealing ring is disposed inside the mounting groove.

[0008] Preferably, a limiting groove is provided at the top of the arc-shaped component, and a limiting component is provided inside the limiting groove. The limiting component is provided with an arc surface.

[0009] Preferably, the inner wall of the arc-shaped component has an arc-shaped groove, and a limiting ring is fixedly connected to the inner wall of the movable groove. The outer side of the limiting ring is located inside the arc-shaped groove. The limiting ring is provided to allow the compressed arc-shaped component to move horizontally. Both the limiting component and the arc-shaped component are made of materials with a certain degree of elasticity.

[0010] Preferably, a spring is provided inside the arc-shaped groove, and the two ends of the spring are fixedly connected to the outer wall of the limiting ring and the inner wall of the arc-shaped groove, respectively. The spring can provide elastic force.

[0011] Preferably, the number of the arc-shaped component, the limiting component, and the arc-shaped sealing ring is four, and the four arc-shaped components, the limiting component, and the arc-shaped sealing ring are arranged in a circumferential array. By setting four limiting components and arc-shaped components, a ring can be formed after the second flange is inserted.

[0012] Preferably, the limiting member and the arc-shaped member are provided with a fixing mechanism, which includes a slot, a rod, a connecting rod, and a limiting hole. The slot is formed on the inner wall of the limiting member, and one end of the rod is inserted into the slot. The inner wall of the limiting slot has a groove, and the other end of the rod is slidably connected to the groove. The limiting hole is formed on the top of the arc-shaped member.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Through the anti-leakage mechanism, the circular ring, movable groove, arc-shaped part, and arc-shaped sealing ring work together. When flange one and flange two are connected, the arc surface of the limiting part is compressed, and the arc-shaped part moves into the movable groove. After flange one and flange two come into contact, the limiting part abuts against the inner wall of flange two to form a seal. The four arc-shaped sealing rings strengthen the seal and form a stable multi-layer sealing system to prevent liquid from seeping through gaps, ensure the integrity and safety of the medium transported by the pipeline system, reduce resource waste, environmental risks and equipment damage caused by leakage, and stabilize the production process.

[0016] 2. By moving the connecting rod to disengage the locking rod from the slot, the limiting component can be removed, allowing for the removal and replacement of the arc-shaped sealing ring. The operation is simple and quick, requiring no complex tools or equipment or disassembly of the entire compensator. This reduces maintenance costs and difficulty, shortens downtime for maintenance, increases equipment operating time and efficiency, and enhances overall reliability and economic benefits.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4As shown, a non-metallic soft corrugated compensator with a leak-proof structure includes a body 1, a flange 2, a flange 3, and a leak-proof mechanism 4. The flange 2 is fixedly connected to both ends of the body 1, the flange 3 is located on one side of the flange 2, and the leak-proof mechanism 4 is located inside the flanges 2 and 3. The flange 3 is installed on an external pipeline. The body 1 is a non-metallic soft corrugated compensator, a common existing technology, and some of its structure is not shown. The leak-proof mechanism 4 includes a ring 41, a movable groove 44, an arc-shaped component 45, a mounting groove 42, and an arc-shaped sealing ring 43. The ring 41 is fixedly connected to the inner wall of the flange 2. The movable groove 44 is located at the top of the ring 41. The arc-shaped component 45 is located inside the movable groove 44. The mounting groove 42 is located on the outer wall of the arc-shaped component 45. The arc-shaped sealing ring 43 is located inside the mounting groove 42. A limiting groove is located at the top of the arc-shaped component 45, and a limiting component 49 is located inside the limiting groove. The limiting component 49 has an arc surface. The limiting element 49 is provided to limit and fix the arc-shaped sealing ring 43, and the arc surface on it is provided to prevent obstruction when the flange 2 is inserted. The inner wall of the arc-shaped element 45 has an arc-shaped groove 47. The inner wall of the movable groove 44 is fixedly connected to the limiting ring 46, and the outer side of the limiting ring 46 is set inside the arc-shaped groove 47. The limiting ring 46 is provided to allow the compressed arc-shaped element 45 to move horizontally. The materials of the limiting element 49 and the arc-shaped element 45 are both elastic. The arc-shaped groove 47 is provided with a spring 48. The two ends of the spring 48 are fixedly connected to the outer wall of the limiting ring 46 and the inner wall of the arc-shaped groove 47, respectively. The spring 48 provides elastic force. There are four arc-shaped elements 45, four limiting elements 49, and four arc-shaped sealing rings 43. The four arc-shaped elements 45, four limiting elements 49, and four arc-shaped sealing rings 43 are arranged in a circumferential array. By setting four limiting elements 49 and four arc-shaped elements 45, a ring can be formed after the flange 2 is inserted.

[0024] Specifically, by connecting flange 2 and flange 3, the ring 41 is inserted into the interior of flange 3, causing the arc surface of the limiting member 49 to be compressed. Then, the arc member 45 moves into the movable groove 44 until flange 2 and flange 3 come into contact. The four limiting members 49 are pressed together to form a ring, and under the action of spring 48, they abut against the inner wall of flange 3 to form a sealing structure, achieving the effect of preventing leakage. The effect of preventing leakage is further enhanced by the cooperation of the four arc-shaped sealing rings 43.

[0025] like Figure 4As shown, a fixing mechanism 5 is provided on the limiting member 49 and the arc-shaped member 45. The fixing mechanism 5 includes a slot 51, a locking rod 52, a connecting rod 54, and a limiting hole 55. The slot 51 is formed on the inner wall of the limiting member 49, and one end of the locking rod 52 is inserted into the inside of the slot 51. A groove is formed on the inner wall of the limiting slot, and the other end of the locking rod 52 is slidably connected to the inside of the groove. The limiting hole 55 is formed on the top of the arc-shaped member 45, and the connecting rod 54 is fixedly connected to the top of the locking rod 52 and passes through the limiting hole 55 to connect with the limiting rod 45. The slidable connection of the positioning hole 55 and the bottom of the limiting member 49 are provided with a circular groove and a circular rod, which can limit the limiting member 49 laterally. The circular rod is fixedly connected to the bottom of the limiting member 49, and the circular groove is opened at the bottom of the inner wall of the limiting groove. After the locking rod 52 is inserted into the locking groove 51, the limiting member 49 can be fixed inside the limiting groove. The inside of the groove is provided with a second spring 53, and the two ends of the second spring 53 are fixedly connected to the other end of the locking rod 52 and the inner wall of the groove, respectively. By setting the second spring 53, the locking rod 52 can be driven to reset.

[0026] Specifically, by moving the connecting rod 54, the connecting rod 54 drives the locking rod 52 to move and disengage from the locking groove 51, thereby releasing the limiting member 49 from restriction. The aging or damaged arc-shaped sealing ring 43 can be disassembled and replaced by removing the limiting member 49.

[0027] The working principle of this utility model is as follows: By connecting flange 2 and flange 3, the ring 41 is inserted into the interior of flange 3, causing the arc surface of the limiting member 49 to be compressed. Then, the arc member 45 moves into the movable groove 44 until flange 2 and flange 3 come into contact. The four limiting members 49 are pressed together to form a ring, and under the action of spring 48, they abut against the inner wall of flange 3 to form a sealing structure, achieving the effect of preventing leakage. The effect of preventing leakage is further enhanced by the cooperation of the four arc sealing rings 43. By moving the connecting rod 54, the connecting rod 54 drives the locking rod 52 to move and disengage from the locking groove 51, thereby releasing the limiting member 49 from restriction. The aging or damaged arc sealing ring 43 can be disassembled and replaced by removing the limiting member 49.
