Description

Sealing element convenient to install and used for flange

Technical Field

The utility model belongs to the technical field of pipeline sealing, and particularly relates to a sealing element convenient to install and used for a flange.

Background

In industrial production and research work, the connection process of a plurality of pipelines is involved, and particularly in the intermediate detection or processing link of continuous production, the connection and the disassembly of fluid conveying pipelines are involved. Many cases involve the connection and disconnection of multiple pipes, for example, during the steps of leak detection, activation, performance testing, etc. in the assembly of fuel cells, a large amount of connection and disconnection work is required, usually manually. As the production rate increases, a large number of pipe connections and disconnections of tens or even hundreds of pipes are required to be performed every day, and from the viewpoint of time efficiency and cost, it is required to simplify the pipe connections, provide conditions for automated connection, and particularly provide a mechanical structure for rapidly connecting and disconnecting the pipe joints.

Referring to fig. 1, conventional butt pipe ends include the use of various flanges, with a common feature being a seal in the middle of the flange. The sealing gaskets of the flanges are made of elastic rubber materials, and particularly when the pipelines are horizontally placed, the sealing gaskets are difficult to place on the joints of the two pipelines to be connected, and are easy to misplace or fall off, even clamp hands, and the operation efficiency is affected. When disassembled, the utility model is easy to drop directly. Common prior art has used sealed the structure that has had the handle of filling up, still need handheld location when the installation, also need handheld when dismantling, occupies more manual work, and assembly work is difficult to accomplish smoothly to single-person operation.

Patent application CN106015781A introduces a technical scheme, and the terminal surface of flange has corresponding location arch and corresponding recess, is similar to a connection transmission of axle, or a technical characterstic of shaft coupling, and to intensity influence greatly, flange thickness need increase a lot. The flange of this application does not have this kind of arch and recess, does not have actual influence to intensity, does not influence the rotation of pipeline center pin moreover.

Patent application CN108916501A describes a technique, in which a sealing gasket is used with through holes corresponding to the bolt holes of a flange, and bolts pass through the through holes to position the gasket on the flange, but during installation, for example, when a pipe is horizontally connected, the gasket cannot be fixed on the flange without bolts and can fall off. The gasket can be fixed on one of the flanges when the pipeline is horizontally connected, and the gasket does not need to be held by hands, which is completely different from the above patent application.

Disclosure of Invention

To the above problem, the utility model provides a sealing member for flange convenient to installation for the high-speed joint and the quick dismantlement of flange are favorable to reducing work high intensity, reduce the error, especially are suitable for application and automation mechanized operation on the detection line.

Since the solution target is a joint, the relevant pipe is not limited to toughness or rigidity.

The above purpose of the utility model is realized by the following technical scheme:

the utility model provides a sealing member for flange convenient to installation, includes that elastic material makes takes the bellied sealed pad of location, and the flange of taking the fixed orifices of check out test set end is equipped with the location round hole with taking the bellied sealed relative position of pad of location, waits to detect the end flange and is not equipped with the location round hole.

Further, the positioning protrusion is in a shape of a cylinder with one side.

Further, the positioning projection has 1 or more.

Furthermore, the positioning round hole on the flange with the fixing hole is a through hole.

Further, the diameter of the positioning round hole is the same as that of the positioning bulge, or the deviation of the diameter of the positioning round hole between the diameters of the positioning bulges is +/-10%.

Compared with the prior art, the utility model has the beneficial effects that:

1) the mounting and dismounting processes can be simplified, the hand-held requirement for positioning the sealing element is reduced in the mounting process, and the falling of the sealing gasket is reduced in the dismounting process;

2) the sealing gasket can be kept fixed on one side of the test equipment in operation, and the end to be tested does not need to be provided with the sealing gasket;

3) the mounting speed and the dismounting speed are improved, and the automatic detection system is favorably applied to an automatic detection system;

4) the bulge structure is used on one side of the detection equipment, the interface of the product to be detected still keeps the conventional standard, and no special requirement is generated on the product leaving the factory in the future.

Drawings

The utility model is further illustrated with reference to the following figures and examples.

FIG. 1 is a schematic view of a seal pair basic structure of a conventional flange;

fig. 2 is a schematic view of a flange seal pair with locating projections.

In the figure: 1. the method comprises the steps of detecting an end flange to be detected, 2, a conventional sealing gasket, 3, a detection equipment end flange, 4, a sealing gasket with a positioning protrusion, 5, a positioning protrusion, 6, a flange with a fixing hole and 7, a positioning circular hole.

Detailed Description

The utility model is described in more detail below with reference to specific examples, without limiting the scope of the utility model. Unless otherwise specified, the experimental methods adopted by the utility model are all conventional methods, and experimental equipment, materials, reagents and the like used in the experimental method can be obtained from commercial sources.

Example 1

Referring to fig. 1, the sealing pair of the conventional structure is composed of an end flange 1 to be detected, a conventional sealing gasket 2 and an end flange 3 of detection equipment, and when the sealing pair is horizontally placed, special attention needs to be paid to the disassembly of the conventional sealing gasket 2 in the middle to prevent the sealing gasket from freely falling when the flange pair is separated. The installation is also inconvenient, and the hand-held positioning is needed.

Referring to fig. 2, assuming that the right side is the direction of the detection device, the utility model adopts a flange 6 with a fixing hole, a sealing gasket 4 with a positioning protrusion is arranged in the middle, and a conventional flange 1 to be detected is arranged on the left side.

The sealing gasket 4 with the positioning protrusion is made of elastic materials and is provided with a single-side cylindrical positioning protrusion 5 perpendicular to a sealing plane, the flange 6 with the fixing hole on the detection equipment side is provided with a positioning round hole 7 at a relative position, the diameter of the positioning round hole 7 is the same as that of the positioning protrusion 5, or the diameter deviation of the positioning round hole 7 between the diameters of the positioning protrusions 5 is +/-10%.

The positioning round hole 7 on the flange 6 with the fixing hole is a through hole.

The number of the positioning projections 5 is 1 or more, in this case 4.

When the end flange 1 to be detected is opened upwards, the sealing gasket 4 with the positioning protrusion is arranged on the flange 6 with the fixing hole, and the sealing gasket can be kept fixed on one side of the testing equipment.

Example 2

During the use, will take protruding sealed pad 4 of location to be close to flange 6 of taking the fixed orifices earlier, the protruding 5 of location corresponds in each location round hole 7 and impresses, then will wait to detect end flange 1 and check out test set end flange 3 and fix according to conventional mode.
