Description

Technical Field

[0001] This utility model belongs to the field of flange sealing gasket technology, specifically a flange sealing gasket with a corrugated compensation structure. Background Technology

[0002] Flange gaskets are mainly used at flange connections. Their function is to fill the tiny gaps between the flange faces through their own elastic deformation, preventing media leakage and achieving a sealing function. They rely on the compressibility and resilience of the gasket material, and under the pre-tightening force of the flange bolts, the gasket fits tightly against the flange face to form a sealing barrier.

[0003] Existing flange gaskets are usually flat gaskets made of materials such as rubber and asbestos. Their elasticity and flexibility are limited. When faced with the deformation of the flange caused by factors such as thermal expansion and contraction, mechanical vibration, and pipeline stress, they are difficult to change accordingly with the flange deformation, which can easily lead to poor sealing and leakage. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a flange gasket with a corrugated compensation structure, which effectively solves the problem of medium leakage caused by poor sealing surface fit.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flange sealing gasket with a corrugated compensation structure, comprising a flange, wherein a second gasket is provided on the outer side of the flange, the second gasket is arranged parallel to the flange, and a corrugated compensation mechanism is provided between the second gasket and the flange.

[0006] The bellows compensation mechanism includes a gasket 1 located on the flange side near the gasket 2 side. A bellows pipe is fixedly connected between gasket 1 and gasket 2. A mounting ring 2 is fixedly connected to the gasket 1 side near the gasket 2 side. A mounting ring 1 is fixedly connected to the gasket 2 side near the flange side. Both mounting ring 1 and mounting ring 2 are located on the outside of the bellows pipe. Two side cylinders are symmetrically fixedly connected to the mounting ring 2 side near the mounting ring 1 side. Side rods are movably sleeved inside the two side cylinders. Side plates are fixedly connected to the ends of the two side rods away from the mounting ring 2 side. Both side plates are fixed to the mounting ring 1 side near the mounting ring 2 side.

[0007] Preferably, a second spring is fixedly connected between the side cylinder and the side plate, and the second spring is sleeved on the outside of the side rod.

[0008] Preferably, a collar is movably sleeved on the outer side of the side cylinder, and two connecting posts are symmetrically and fixedly connected between the collar and the side plate.

[0009] Preferably, a spring is fixedly connected between the collar and the mounting ring, and the spring is disposed on the outside of the side cylinder.

[0010] Preferably, two brackets are symmetrically fixedly connected to the side of the first mounting ring near the second mounting ring, and two limiting screws are symmetrically fixedly connected to the side of the second mounting ring near the first mounting ring, with the two brackets respectively sleeved on the outside of the two limiting screws.

[0011] Preferably, the inner side of the bracket is tightly fitted with a limiting nut, and the limiting nut is threaded onto the outer side of the limiting screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting the bellows, the sealing between gasket one and gasket two can be guaranteed. And through the cooperation between mounting ring two, mounting ring one, side cylinder, spring one, connecting column, side plate, side rod and spring two, it is easy to elastically connect gasket one and gasket two, thereby ensuring that the sealing surface fits tightly and avoiding media leakage.

[0014] 2. The fit between the limiting screw, bracket, limiting nut, mounting ring one and mounting ring two facilitates the restriction of the displacement between gasket one and gasket two within the design allowable range, preventing excessive expansion or deformation.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1, by Figure 1 The present invention relates to a flange gasket with a corrugated compensation structure, comprising a flange 1, a gasket 3 on the outer side of the flange 1, the gasket 3 being arranged parallel to the flange 1, and a corrugated compensation mechanism 2 being provided between the gasket 3 and the flange 1.

[0024] Specifically, by Figure 2-3 The bellows compensation mechanism 2 includes a gasket 201 located on the flange 1 near the gasket 3. A bellows 205 is fixedly connected between the gasket 201 and the gasket 3. A mounting ring 204 is fixedly connected to the gasket 201 near the gasket 3. A mounting ring 202 is fixedly connected to the gasket 3 near the flange 1. Both mounting rings 202 and 204 are located outside the bellows 205. Two side cylinders 203 are symmetrically fixedly connected to the mounting ring 204 near the mounting ring 202. Side rods 2012 are movably sleeved inside each of the two side cylinders 203. Side plates 2011 are fixedly connected to the end of side rod 2012 away from mounting ring 204. Both side plates 2011 are fixed to the side of mounting ring 1 202 near mounting ring 204. Spring 2010 is fixedly connected between side cylinder 203 and side plate 2011. Spring 2010 is sleeved on the outside of side rod 2012. A collar 207 is movably sleeved on the outside of side cylinder 203. Two connecting posts 209 are symmetrically fixedly connected between collar 207 and side plate 2011. Spring 208 is fixedly connected between collar 207 and mounting ring 204. Spring 208 is sleeved on the outside of side cylinder 203.

[0025] In use, a bellows 205 is first installed between gasket 1 201 and gasket 2 3 to ensure a tight seal between them. When gasket 1 201 and gasket 2 3 are compressed, the side rod 2012 and the side cylinder 203 move. At this time, spring 2 2010 deforms, and the collar 207 slides along the side cylinder 203, while spring 1 208 deforms, thereby elastically connecting gasket 1 201 and gasket 2 3. Finally, under the action of the elastic force of spring 2 2010 and spring 1 208, the sealing surfaces are tightly fitted to prevent media leakage.

[0026] Specifically, by Figure 4As shown, two brackets 206 are symmetrically fixedly connected to the side of mounting ring 1 202 near mounting ring 204, and two limiting screws 2013 are symmetrically fixedly connected to the side of mounting ring 204 near mounting ring 1 202. The two brackets 206 are respectively sleeved on the outside of the two limiting screws 2013, and the inside of the brackets 206 is tightly attached to the limiting nut 2014. The limiting nut 2014 is threaded onto the outside of the limiting screw 2013.

[0027] In use, bracket 206 is fitted onto the outside of limit screw 2013, and limit nut 2014 is threaded onto the outside of limit screw 2013 to limit bracket 206, thus limiting the displacement between gasket 1 201 and gasket 2 3 within the design allowable range, thereby preventing excessive expansion or deformation.
