Embodiment Construction

[0017] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0018] Such as figure 1 As shown, a closeable flange for pipeline connection includes a flange body 1, and the flange body 1 is divided into a first part, a second part and a third part in sequence from the axis outward, and the first part is The opening 2 for communicating with the pipeline, the second part is equipped with a closeable device, and the third part is evenly opened around the circumference with a number of bolt holes for mutual connection between flanges.

[0019] The closeable device includes a first operating rod 3 and a second operating rod 4 located on the same plane, and the first operating rod 3 and the second operating rod 4 have the same length. The first operating rod 3 and the second operating rod 4 are cross-connec...

Abstract

The invention discloses a closing-type flange for pipeline connection. The closing-type flange comprises a flange plate body. The flange plate body is divided into a first part, a second part and a third part sequentially from the axis to the outside; the first part serves as a through opening communicating with a pipeline, a closing device is mounted in the second part, and a plurality of bolt holes are evenly formed in the third part around the circumference. The closing device comprises a first operating rod and a second operating rod which are hinged in a crossed mode; the first operatingrod and the second operating rod can rotate relatively around the crossed connection position; and baffles are mounted at the ends, located at the second part, of the first operating rod and the second operating rod correspondingly and are parallel to the flange plate body. The closing-type flange is simple in structure, flow cutoff and weakening of the flow are achieved through splicing of the baffles, and moving operation of the baffles is convenient, rapid and easy.

Description

technical field [0001] The invention relates to the technical field of flanges, in particular to a sealable flange used for pipeline connection. Background technique [0002] There are many kinds of flanges currently in use, most of which are used for pipeline connections. In use, the pipes are connected by flanges to carry out the transportation of long-distance water sources or other objects. In the face of long-distance operations, when it is necessary to work on a part of them, if the entire pipeline is closed, it will have a greater impact and be more cumbersome. The invention aims at suspending the transportation of a certain part or slowing down the flow of a certain part in the transportation process, and improves the flange used for pipeline connection. Contents of the invention [0003] In order to solve the above problems, the present invention provides a closeable flange for pipeline connection with simple structure and simple operation. [0004] The present...
