Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a pressure-resistant flange with stable butt connection. Background Art

[0002] Flanges are parts that connect pipes to each other and are used to connect pipe ends. Flanges are also used on equipment inlets and outlets to connect two devices, such as reducer flanges. As a key component for connecting pipes, flanges play a vital role in the fields of petroleum, chemical industry, food, etc.

[0003] For example, the utility model with application number CN202223174597.0 discloses a pressure-resistant flange. The utility model increases the pressure resistance of the flange by setting transverse and vertical reinforcement ribs in the flange, and cross-setting the reinforcement ribs. Pressure-resistant pads are set at the intersection of the bolt head and the nut, that is, above and below the mounting hole to help increase the pressure resistance. Sealing pads and sealing rings are set at the circumferential surface and center through hole of the flange to improve the sealing of the flange. However, flanges are generally fastened with bolts. When manually screwing the bolts into the mounting holes, the centering of the flange is difficult to grasp, and it is easy to cause the gasket to move, affecting the stability of the docking.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a pressure-resistant flange with stable docking is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a stable butt-jointed pressure-resistant flange to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stable docking pressure-resistant flange, comprising a first flange and a slot, a plug-in plate is arranged on the right side of the first flange, and a toothed plate is installed on the surface of the plug-in plate, a gasket groove is opened on the right side surface of the first flange, and a second flange is arranged on the right side of the first flange, mounting holes are opened on the surfaces of the first flange and the second flange, the slot is opened on a side of the second flange close to the first flange, and a compression spring is arranged inside the slot, the end of the compression spring is connected to a moving block, and a protrusion is arranged through the opening on the surface of the moving block, and a guide groove is opened on the top and bottom of the second flange.

[0007] Furthermore, the plug-in plates are symmetrically distributed about the transverse center axis of the first flange, and two of the plug-in plates and two of the toothed plates are provided.

[0008] Furthermore, the slot has a square structure, and the second flange is elastically connected to the moving block via a compression spring.

[0009] Furthermore, the moving block occupies one half of the thickness of the protruding block, and the thicknesses of the plug-in plate, the toothed plate and the moving block are the same.

[0010] Furthermore, a pipeline is provided on a side of the first flange away from the second flange, and a pipeline is also provided on a side of the second flange away from the first flange.

[0011] Furthermore, reinforcement blocks are installed on the outer side of the pipeline, and reinforcement ribs are connected between the reinforcement blocks.

[0012] Furthermore, the reinforcement blocks are in a right-angled trapezoidal structure, and the reinforcement blocks are distributed in a circular shape and at equal intervals along the outer side of the pipeline.

[0013] The utility model provides a pressure-resistant flange with stable docking, which has the following beneficial effects:

[0014] 1. The utility model presses the moving block to deform the compression spring, and then extends the plug-in plate and the toothed plate into the slot on the side of the second flange until there is no gap between the first flange and the second flange, and then releases the moving block. The elastic force of the compression spring drives the moving block to move longitudinally along the guide groove, so that the protrusion is stuck in the groove of the toothed plate, thereby locking the first flange and the second flange, and ensuring the stability of the first flange and the second flange after docking.

[0015] 2. The reinforcing blocks of the utility model are arranged at equal intervals around the pipeline, achieving the purpose of lightweight while ensuring the compressive performance of the first flange and the second flange. The reinforcing blocks are connected by reinforcing ribs, which can improve the rigidity of the first flange and the second flange, making the first flange and the second flange less likely to deform under high pressure conditions.

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, a stable butt-jointed pressure-resistant flange comprises a first flange 1 and a slot 7, a plug-in plate 2 is arranged on the right side of the first flange 1, and a toothed plate 3 is installed on the surface of the plug-in plate 2, a gasket groove 4 is provided on the right side surface of the first flange 1, and a second flange 5 is provided on the right side of the first flange 1, and mounting holes 6 are provided on the surfaces of the first flange 1 and the second flange 5, the slot 7 is provided on a side of the second flange 5 close to the first flange 1, and a compression spring 8 is provided inside the slot 7, a moving block 9 is connected to the end of the compression spring 8, and a protrusion 10 is provided through the opening of the surface of the moving block 9, a guide groove 11 is provided at the top and bottom of the second flange 5, the plug-in plates 2 are symmetrically distributed about the transverse central axis of the first flange 1, and two plug-in plates 2 and toothed plates 3 are each provided, the slot 7 is a square structure, the second flange 5 is elastically connected to the moving block 9 through the compression spring 8, the moving block 9 occupies half of the thickness of the protrusion 10, and the plug-in plate 2, the toothed plate 3 and the moving block 9 have the same thickness.

[0023] The specific operation is as follows: the compression spring 8 is deformed by pressing the movable block 9, and then the plug-in plate 2 and the toothed plate 3 are extended into the slot 7 on the side of the second flange 5, and the movable block 9 is released until there is no gap between the first flange 1 and the second flange 5. The elastic force of the compression spring 8 drives the movable block 9 to move longitudinally along the guide groove 11, so that the protrusion 10 is stuck in the groove of the toothed plate 3, thereby locking the first flange 1 and the second flange 5, ensuring the stability of the first flange 1 and the second flange 5 after docking.

[0024] like Figure 3 As shown, a pipe 12 is provided on a side of the first flange 1 away from the second flange 5, and a pipe 12 is also provided on a side of the second flange 5 away from the first flange 1. Reinforcement blocks 13 are installed on the outer side of the pipe 12, and reinforcing ribs 14 are connected between the reinforcement blocks 13. The reinforcement blocks 13 are of a right-angled trapezoidal structure, and the reinforcement blocks 13 are distributed in a circular shape and at equal intervals along the outer side of the pipe 12.

[0025] The specific operation is as follows: the reinforcement blocks 13 are arranged at equal intervals around the pipe 12, so as to achieve the purpose of lightweight while ensuring the compression resistance of the first flange 1 and the second flange 5. The reinforcement blocks 13 are connected by reinforcement ribs 14, which can improve the rigidity of the first flange 1 and the second flange 5, so that the first flange 1 and the second flange 5 are not easily deformed under high pressure conditions.

[0026] In summary, when the butted and stable pressure-resistant flange is used, the moving block 9 at the top and bottom of the second flange 5 is first pressed to deform the two compression springs 8 at the same time, and then the plug-in plate 2 and the toothed plate 3 on the side of the first flange 1 with the gasket in the gasket groove 4 are inserted into the slot 7 on the side of the second flange 5 until there is no gap between the first flange 1 and the second flange 5, and the moving block 9 is released, so that the moving block 9 can rely on the elastic force provided by the compression spring 8 to move along the guide groove 11 toward the toothed plate 3. Since the surface of the toothed plate 3 is equidistantly provided with grooves, when the protrusion 10 and the groove of the toothed plate 3 form a snap connection, the gasket can be locked in the gasket groove 4, thereby ensuring the sealing of the connection between the first flange 1 and the second flange 5 and the stability after the two are butted, so that the mounting holes 6 on the surface of the first flange 1 and the mounting holes 6 on the surface of the second flange 5 are aligned accordingly, which is convenient for manually screwing the bolts into the mounting holes 6;

[0027] Since a pipe 12 is provided on each of the first flange 1 and the second flange 5, reinforcing blocks 13 fixedly connected to the first flange 1 and the second flange 5 are arranged at equal intervals around the outer sides of the two pipes 12, and adjacent reinforcing blocks 13 are connected by reinforcing ribs 14, so that the first flange 1 and the second flange 5 have high pressure resistance.
