Description

Technical Field

[0001] The utility model belongs to the technical field of flanges, in particular to a sealing gasket for flanges which is easy to replace. Background Art

[0002] Flange is a common component used to connect two pipes, containers or equipment. They are usually used in piping systems, heat exchangers, reactors, pumps and other process equipment. The purpose of flange connection is to ensure the seal between the two components to prevent the leakage of fluids, gases or solid particles. The flange sealing gaskets currently used are not very convenient to replace after damage, because the operator needs to carefully align the hole position of the gasket with the bolt hole position on the flange, which is time-consuming and laborious. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides a flange sealing gasket that is easy to replace, which solves the problem that the currently used flange sealing gasket is not convenient to replace after being damaged, because the operator needs to carefully align the hole position of the gasket with the bolt hole position on the flange plate, which is time-consuming and laborious.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flange sealing gasket that is easy to replace, comprising a first flange plate and a second flange plate, wherein the first flange plate and the second flange plate are each provided with four bolt holes, the first flange plate and the second flange plate are each provided with through holes, a sealing device is clamped in the first flange plate and the second flange plate, and four first magnetic suction sheets are connected to the second flange plate;

[0005] The sealing device comprises an initial layer, an anti-sticking layer is connected to the reinforcing layer, and four second magnetic sheets are connected inside the initial layer.

[0006] As a further solution of the utility model: a filling layer is connected to the anti-sticking layer, and a contact layer is connected to the filling layer.

[0007] As a further solution of the utility model: a reinforcement layer is connected to the initial layer, and the first magnetic attraction sheet corresponds to the position of the bolt hole.

[0008] As a further solution of the utility model: the initial layer overlaps with the second flange, and the contact layer overlaps with the first flange.

[0009] As a further solution of the utility model: the first magnetic attraction sheet is clamped in the second magnetic attraction sheet, and the first magnetic attraction sheet and the second magnetic attraction sheet both correspond to the positions of the bolt holes.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The flange sealing gasket which is easy to replace is provided with a first flange, a second flange, a first magnetic sheet, an initial layer and a second magnetic sheet. When the gasket needs to be replaced, the first flange is removed, and then the gasket assembly is taken out, and then the new gasket assembly is held, and the initial layer is matched with the second flange. At this time, the second magnetic sheet in the initial layer generates magnetic force with the first magnetic sheet, and the magnetic force clamps the second magnetic sheet in the second magnetic sheet, thereby realizing rapid installation of the gasket and avoiding the need for the operator to carefully align the hole position of the gasket with the bolt hole position on the flange, which is both time-consuming and laborious.

[0012] 2. The flange sealing gasket that is easy to replace is provided with an initial layer, a reinforcing layer, an anti-sticking layer, a filling layer and a contact layer. When subjected to high temperature, the initial layer and the reinforcing layer ensure that the gasket maintains stability and structural strength at high temperature to prevent deformation or damage. The anti-sticking layer prevents adhesion between the gasket and the flange due to high temperature. The filling layer and the contact layer improve the contact sealing performance between the gasket and the flange to ensure the sealing effect in a high temperature environment. Through the interaction of these layers, the gasket can maintain good sealing performance and durability at high temperature. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-4As shown, the utility model provides a technical solution: a flange sealing gasket that is easy to replace, comprising a first flange 1 and a second flange 2, wherein the first flange 1 and the second flange 2 are each provided with four bolt holes 3, the first flange 1 and the second flange 2 are each provided with a through hole 4, a sealing device 5 is clamped in the first flange 1 and the second flange 2, and four first magnetic suction sheets 6 are connected to the second flange 2;

[0020] The sealing device 5 includes an initial layer 51. By setting the initial layer 51 and the second magnetic sheet 7, the initial layer 51 cooperates with the second magnetic sheet 7, so that the second magnetic sheet 7 is connected to the initial layer 51, so that the second magnetic sheet 7 does not protrude in the initial layer 51.

[0021] The reinforcing layer 52 is connected with an anti-sticking layer 53, and the initial layer 51 is connected with four second magnetic sheets 7. By providing the first magnetic sheet 6 and the second magnetic sheet 7, the first magnetic sheet 6 cooperates with the second magnetic sheet 7 to achieve that when the two are close to each other, magnetic force is generated, so that the two can be magnetically attracted to each other;

[0022] The anti-adhesive layer 53 is connected to a filling layer 54, the filling layer 54 is connected to a contact layer 55, and the initial layer 51 is connected to a reinforcement layer 52. By providing the initial layer 51 and the reinforcement layer 52, the initial layer 51 cooperates with the reinforcement layer 52, so that when subjected to high temperature, the initial layer 51 and the reinforcement layer 52 ensure that the gasket maintains stability and structural strength at high temperature to prevent deformation or damage;

[0023] The first magnetic sheet 6 corresponds to the position of the bolt hole 3, the first magnetic sheet 6 is clamped in the second magnetic sheet 7, the first magnetic sheet 6 and the second magnetic sheet 7 both correspond to the position of the bolt hole 3, the initial layer 51 overlaps the second flange 2, and the contact layer 55 overlaps the first flange 1.

[0024] The working principle of the utility model is:

[0025] When the gasket needs to be replaced, remove the first flange 1, then take out the gasket assembly, and then take the new gasket assembly, and match the initial layer 51 with the second flange 2. At this time, the second magnetic sheet 7 in the initial layer 51 and the first magnetic sheet 6 generate magnetic force, and the magnetic force clamps the second magnetic sheet 7 in the second magnetic sheet 7, thereby completing the operation of quickly replacing the gasket.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connection", "sliding connection" and "hinge" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
