Description

An aluminum alloy flange with a sealing structure Technical Field

[0001] This utility model relates to the field of aluminum alloy flange technology, and in particular to an aluminum alloy flange with a sealing structure. Background Technology

[0002] Aluminum alloy flanges are a widely used type of flange. When connecting aluminum alloy flanges to other parts, a sealing structure is required to prevent leakage. Chinese patent CN217177801U discloses an aluminum alloy flange with a sealing structure, including a flange body. The flange body includes a first connecting plate, a second connecting plate, a sealing seat, and a connecting groove. The first connecting plate has several first mounting holes in its center, and the second connecting plate has several second mounting holes in its center. The sealing seat includes a rubber ring, an outer sealing gasket, and an inner hoop. The inner hoop is fixedly connected to the inner side of the rubber ring, and the outer sealing gasket is fixedly connected to the outer side of the rubber ring. This utility model provides an aluminum alloy flange with a sealing structure, featuring a first connecting plate, a second connecting plate, a sealing seat, a connecting groove, and a waterproof sealing membrane. The sealing seat includes a rubber ring, an outer sealing gasket, and an inner hoop. The rubber ring and outer sealing gasket have a certain degree of elastic interference fit for sealing, and the waterproof sealing membrane further strengthens the sealing performance of the connection. The entire flange body provides good sealing performance during use, reducing water leakage at pipe connections and making it convenient to use.

[0003] The aforementioned patent only provides a single seal from the inside using a sealing ring, which is not very effective. In addition, the patent lacks elastic compensation, and the sealing ring shrinks when exposed to low temperatures, causing the seal to break down and leading to leakage. Therefore, there is an urgent need to develop an aluminum alloy flange with a sealing structure that provides double sealing from both the inside and outside, has better sealing performance, and has compensation capabilities to eliminate the effects of shrinkage when exposed to cold. This would overcome the shortcomings in current applications and meet current needs. Summary of the Invention

[0004] The purpose of this invention is to provide an aluminum alloy flange with a sealing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An aluminum alloy flange with a sealing structure includes an aluminum alloy flange, a sealing sleeve, a locking mechanism, a sealing ring, and a second spring. The aluminum alloy flange has a mounting groove, within which a sealing ring extending to its outer side is installed. Multiple second springs connected to the sealing ring are fixed within the mounting groove. A sealing sleeve is fixedly connected to the outer side of the aluminum alloy flange. A locking mechanism is detachably installed on the outer side of the sealing sleeve. The locking mechanism includes: an elastic clamp, a boss, a cavity, an arc-shaped pressure strip, a first spring, a fastening bolt, and a fastening nut. The upper end of the elastic clamp has two bosses, which are detachably fixed together by the fastening bolt and the fastening nut. A cavity is provided within the elastic clamp, and an arc-shaped pressure strip is installed on both the left and right sides of the cavity, extending to the outside of the cavity. The arc-shaped pressure strip is elastically connected to the inner wall of the cavity via the first spring.

[0007] Preferably, the two arc-shaped pressure strips are arranged symmetrically on the left and right.

[0008] Preferably, the aluminum alloy flange is provided with multiple mounting holes for bolts to pass through.

[0009] Preferably, both the sealing sleeve and the sealing ring are made of nitrile rubber.

[0010] The beneficial effects of this utility model are as follows: When the aluminum alloy flange with the sealing structure is connected to other external parts, the sealing ring is placed against the connection surface of the external part, the sealing sleeve is put on the outer wall of the external part, and then the aluminum alloy flange is fixed to the external part by bolts and nuts. The sealing ring comes into contact with the external connection and is squeezed, so that it fits tightly with the external part, sealing from the inside. The second spring is compressed. Then, the fastening bolts and fastening nuts are tightened, so that the elastic clamp gradually tightens. The elastic clamp presses the sealing sleeve onto the external part, sealing from the outside. At the same time, the arc-shaped pressure strip squeezes the sealing sleeve, and the first spring is compressed. The sealing sleeve and the sealing ring provide a double seal, which improves the sealing effect. When the sealing sleeve and sealing ring shrink due to cold, the second spring provides elastic compensation for the sealing ring, and the first spring provides elastic compensation for the arc-shaped pressure strip, so that the arc-shaped pressure strip presses the sealing sleeve tightly, thereby eliminating the effect of shrinkage due to cold. In summary, this utility model provides double sealing from both the inside and outside, resulting in better sealing performance and compensation capabilities, which can eliminate the effects of contraction when exposed to cold.

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 scope of protection of the present utility model.

[0021] Specific implementation examples are given below.

[0022] Referring to Figures 1 to 7, in this embodiment of the present invention, an aluminum alloy flange with a sealing structure includes an aluminum alloy flange 1, a sealing sleeve 2, a locking mechanism 3, a sealing ring 4, and a second spring 5. The aluminum alloy flange 1 has a mounting groove 101, in which a sealing ring 4 extending to its outer surface is installed. Multiple second springs 5 ​​connected to the sealing ring 4 are fixed within the mounting groove 101. A sealing sleeve 2 is fixedly connected to the outer side of the aluminum alloy flange 1. A locking mechanism 3 is detachably installed on the outer side of the sealing sleeve 2. The locking mechanism 3 includes: an elastic clamp 301, a boss 302, and a cavity 30. 3. An arc-shaped pressure strip 304, a first spring 305, a fastening bolt 306, and a fastening nut 307. The upper end of the elastic clamp 301 is provided with two bosses 302. The two bosses 302 are detachably fixed to each other by fastening bolts 306 and fastening nuts 307. The elastic clamp 301 is provided with a cavity 303. An arc-shaped pressure strip 304 is installed on both the left and right sides of the cavity 303. The arc-shaped pressure strips 304 extend to the outside of the cavity 303. The two arc-shaped pressure strips 304 are arranged symmetrically on the left and right. The arc-shaped pressure strips 304 are elastically connected to the inner wall of the cavity 303 by the first spring 305.

[0023] The aluminum alloy flange 1 is provided with a plurality of mounting holes 102 for bolts to pass through.

[0024] Both the sealing sleeve 2 and the sealing ring 4 are made of nitrile rubber.

[0025] Working principle: When the aluminum alloy flange 1 is connected to other external parts, the sealing ring 4 is aligned with the connection surface of the external part, the sealing sleeve 2 is fitted onto the outer wall of the external part, and then the aluminum alloy flange 1 is fixed to the external part with bolts and nuts. The sealing ring 4 comes into contact with the external connection and is compressed, making it fit tightly against the external part and sealing from the inside. The second spring 5 is also compressed. Then, the fastening bolts 306 and fastening nuts 307 are tightened, causing the elastic clamp 301 to gradually tighten. The sealing sleeve 2 is pressed onto the external part by the elastic clamp 301, sealing from the outside. At the same time, the sealing sleeve 2 is squeezed by the arc-shaped pressure strip 304, and the first spring 305 is compressed. The sealing sleeve 2 and the sealing ring 4 provide a double seal, which is more effective. When the sealing sleeve 2 and the sealing ring 4 shrink due to cold, the second spring 5 provides elastic compensation for the sealing ring 4, and the first spring 305 provides elastic compensation for the arc-shaped pressure strip 304, so that the arc-shaped pressure strip 304 presses the sealing sleeve 2 tightly, thereby eliminating the effect of shrinkage due to cold.
