Description

Sealing flange for pressure test

Technical Field

The utility model relates to a flange field, concretely relates to sealing flange for pressure testing.

Background

A flange, also known as a flange collar or flange. The flange is a part for connecting the shafts and is used for connecting pipe ends; there are also flanges on the inlet and outlet of the equipment for the connection between two pieces of equipment, such as reducer flanges. The flange connection or flange joint is a detachable connection which is formed by connecting a flange, a gasket and a bolt with each other to form a group of combined sealing structures. The pipeline flange is a flange for piping in a pipeline device, and is used on equipment to be an inlet and outlet flange of the equipment. The flanges are provided with holes, and the two flanges are tightly connected through bolts. The flanges are sealed with gaskets. The existing flange is single in function, poor in flexibility, poor in supercharging effect, inconvenient for people to use and inconvenient to disassemble and assemble.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a sealing flange for pressure testing just for solving above-mentioned problem to solve above-mentioned problem.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model provides a sealing flange for pressure testing, including ring flange, O type sealing washer, runner, long neck pipe and bolt hole, the bottom of ring flange is connected with long neck pipe, long neck pipe's inside is equipped with the runner, the top of ring flange is equipped with O type sealing washer, the top of ring flange evenly is equipped with a plurality of bolt hole.

As an optimized technical scheme of the utility model, ring flange and long neck pipe are made through the mould casting.

As an optimal technical scheme of the utility model, O type sealing washer is installed on ring flange top middle part.

The utility model discloses the beneficial effect who reaches is: the flange is mainly used for conveniently testing the pressure born by various different flange joints, and is convenient to install and seal due to the sealing ring, a series of operations such as gasket installation and welding required by the traditional flange are omitted, the pressure of various sizes can be born, the flange can be used at 0-15MPa, the O-shaped ring is adopted for sealing, the flange is simple and convenient, and the whole flange is easy to disassemble and assemble, is very convenient and fast, has a simple structure and is convenient to popularize.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:

fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a cross-sectional view of the present invention.

In the figure: 1. a flange plate; 2. an O-shaped sealing ring; 3. a flow channel; 4. a long neck tube; 5. bolt holes.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Examples

As shown in fig. 1-2, the utility model provides a sealing flange for pressure testing, including ring flange 1, O type sealing washer 2, runner 3, long neck pipe 4 and bolt hole 5, the bottom of ring flange 1 is connected with long neck pipe 4, and the inside of long neck pipe 4 is equipped with runner 3, and the top of ring flange 1 is equipped with O type sealing washer 2, and the top of ring flange 1 evenly is equipped with a plurality of bolt hole 5.

The flange 1 and the long neck pipe 4 are manufactured by die casting.

The O-shaped sealing ring 2 is arranged on the middle part of the top end of the flange plate 1.

The device is a sealing flange for pressure testing, including ring flange 1, O type sealing washer 2, runner 3, long neck pipe 4 and bolt hole 5, this flange mainly is the pressure that can bear that is used for the various different flange knecks of convenient test, because there is the sealing washer, so the installation is sealed more convenient, it needs a series of operations such as gasket and welding to install to have saved traditional flange, can bear the pressure of various sizes, can all use at 0-15MPa, adopt O type circle to seal, and is simple and convenient, and the dismouting of whole flange is very easy, and is very convenient, moreover, the steam generator is simple in structure, and the convenience is promoted.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
