Abstract

An ellipticity-controllable flanged connecting pipe comprising a flanged connecting pipe body (1). Several metal blocks (2) are welded to the inner wall at one extremity of the flanged connecting pipe body (1) that is inserted into a pipeline. The metal blocks (2) are distributed symmetrically along the inner wall of the flanged connecting pipe. Supporting steel pipes (3) are welded to the metal blocks (2). One extremity of the supporting steel pipes (3) is welded onto one of the metal blocks (2), while the other extremity is welded onto a metal plate (4). The supporting steel pipes (3) are welded together with the metal plate (4) at the point of intersection. Because of the supporting effect provided by the supporting steel pipes, the flanged connecting pipe allows the outer wall of the flanged connecting pipe to not deform easily when subjected to effects of an external force, has ellipticity well controlled, is easy to arrange, and facilitates installation and removal.

Description

一种可控制椭圆度的法兰连接管  Flange connecting tube capable of controlling ellipticity
技术领域 Technical field
本实用新型涉及一种法兰连接管，具体涉及一种可控制椭圆度的 法兰连接管。  The utility model relates to a flange connecting pipe, in particular to a flange connecting pipe capable of controlling ellipticity.
背景技犬 Background dog
目前， 法兰连接管用于输水钢管的连接已经非常普遍， 这是因为 法兰连接管连接方式比较简单， 连接密封性较好， 方便安装和拆卸。 但是法兰连接管没有法兰板的一端比较薄弱，在运输过程中或者安装 过程中， 容易受到外部的挤压而使本身的椭圆度发生变化。而法兰连 接管没有法兰板一端的直径尺寸是按照连接尺寸设计好的，一旦法兰 连接管的椭圆度发生改变， 就会使插入钢管一端无法与钢管内壁配 合， 导致连接困难， 密封性也受到影响。  At present, the connection of flanged pipes for water-conveying steel pipes has become very common. This is because the flange connecting pipes are relatively simple in connection, and the joint sealing is good, which is convenient for installation and disassembly. However, the end of the flange connecting pipe without the flange plate is relatively weak, and it is easily subjected to external pressing during transportation or during installation to change its own ellipticity. The diameter of the flange connecting pipe without the flange plate is designed according to the connection size. Once the ellipticity of the flange connecting pipe is changed, the end of the inserted steel pipe cannot be matched with the inner wall of the steel pipe, resulting in difficulty in connection and sealing. Also affected.
