Description

Cloth-based sealing gasket

Technical Field

The utility model relates to a sealed technical field that fills up, more specifically relates to a cloth base is sealed fills up.

Background

At present, in the manufacturing technology of sealing gaskets for motor vehicle parts, the sealing gasket is a sealing spare part for fluid passages of machinery, equipment, pipelines and the like, and plays a role in sealing the equipment and the pipelines. Prior art gaskets are typically made of a sheet material such as paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile, fiberglass or plastic polymers, and the like, a material placed between two planes to enhance the seal, and a sealing element disposed between the sealed faces to prevent fluid leakage. The common sealing gasket in the prior art has the following technical problems:

1. the common sealing gasket has poor sealing performance due to the fact that the machined surface is not perfect and the machined surface roughness is poor;

2. the common metal sealing gasket only has one layer of metal sheet, does not have the self-adaptive sealing function, has large use limitation, often reduces the sealing effect, and leads to sealing failure and loss when serious;

3. after the common metal sealing gasket is used for a long time, the common metal sealing gasket is easy to rust, and the sealing effect is greatly influenced;

4. the common non-metal sealing gasket is often not high in strength, poor in pressure resistance and poor in fracture resistance, and cannot meet special requirements of some mechanical parts.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems that the prior sealing gasket has poor sealing performance, is easy to rust after being used for a long time, and has poor pressure resistance and folding resistance; the cloth-based sealing gasket has good sealing performance, is not easy to rust, and has good pressure resistance and folding resistance.

In order to solve the problems, the cloth-based sealing gasket comprises a cloth-based sealing gasket body and a silica gel sleeve; the silica gel sleeve wraps the cloth-based sealing pad body; the cloth-based sealing pad body and the silica gel sleeve are provided with a plurality of bolt holes; the cloth-based sealing gasket body comprises an elastic layer, a nylon cloth layer, an adhesive layer and a metal gauze layer; the nylon cloth layer is bonded with the metal gauze layer through the adhesive layer; the elastic layers are two and are respectively arranged on the upper side of the nylon cloth layer and the lower side of the metal gauze.

In particular, the silica gel sleeve is uniformly provided with semicircular round points formed by the elastomer.

In particular, the adhesive layer uses a two-part epoxy adhesive.

In particular, the metal gauze is made of fine iron wires.

In particular, the nylon cloth layer, the adhesive layer and the metal gauze layer are all a plurality of layers.

In particular, the elastic layer is made of an elastic glue material.

The utility model has the advantages that:

1. the utility model discloses set up the sealed pad body of silica gel cover parcel cloth base, sealing performance is good, and silica gel takes place deformation easily and resilience makes the utility model discloses higher crushing resistance has, and the semi-circular dot that the elastomer that silica gel cover surface was evenly arranged formed has strengthened by sealed object with the utility model discloses the frictional force of contact surface plays anti-skidding effect.

2. The utility model discloses set up the metal gauze stratum reticulare, the metal gauze stratum reticulare structure is firm to be difficult to take place to buckle, therefore the metal gauze stratum reticulare the utility model discloses stronger anti folding nature has for this use is novel to be difficult to take place unfavorable phenomena such as distortion deformation when using.

3. The utility model discloses set up the nylon cloth layer, the material route of getting of nylon cloth material is wider, and the price is very cheap, consequently makes the utility model discloses a great reduction of cost of manufacture easily popularizes, and the nylon cloth material is different from the metal material and rusts easily moreover, therefore has improved the utility model discloses a life.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.

As shown in fig. 1 and fig. 2, the cloth-based gasket of the present embodiment includes a cloth-based gasket body and a silicone sleeve 1. The silica gel cover 1 wraps the cloth-based sealing pad body. Semicircular round points 7 formed by an elastomer are uniformly distributed on the silica gel sleeve 1. The cloth-based sealing pad body and the silica gel sleeve 1 are provided with a plurality of bolt holes 2; the cloth-based gasket body includes an elastic layer 3, a nylon cloth layer 4, an adhesive layer 5, and a metal gauze layer 6. The nylon cloth layer 4 is adhered with the metal gauze layer 6 through the adhesive layer 5, the adhesive layer 5 adopts bi-component epoxy resin adhesive, and the metal gauze 6 is made of thin iron wires. The two elastic layers 3 are respectively arranged on the upper side of the nylon cloth layer 4 and the lower side of the metal gauze 6. The nylon cloth layer 4 occupies the largest proportion of the whole cloth-based sealing gasket body. The nylon cloth layer 4, the adhesive layer 5 and the metal gauze layer 6 are all a plurality of layers. The elastic layer 3 is made of an elastic glue material.

The embodiment of the utility model provides a theory of operation and application method:

the utility model discloses a silica gel cover 1 takes place to deform when being extruded therefore seals the application of force object, and the semi-circular dot of elastomer on the silica gel cover 1 can increase frictional force between the two when contacting with the application of force object for the application of force object is difficult to take place to drop when applying pressure to silica gel cover 1, set up the bolt hole make things convenient for two application of force objects to pass through the nut make it with the utility model discloses can zonulae occludens reach sealed effect, the utility model discloses a metal gauze stratum reticulare 6 is interweaved by the metal wire that interweaves and forms, and the structure fastening is difficult to take place to buckle and the fracture, therefore makes the nylon cloth layer 4 structure of relative soft multilayer be difficult to take place to distort and warp, therefore makes the utility model discloses there is very strong anti-folding nature, is difficult to be damaged.
