Abstract
The utility model discloses a double-face flange, belonging to the double-face flange. A flange, the central position of the flange is provided with a main hole, the edge of the flange is provided with a pair of bolt holes, the end face of the flange is a convex-concave seal face, and the other end face is a dovetail groove seal face. The flange adopts a thick round steel plate, and the both sides of the steel plate are respectively turned out the flange end-face of the convex-concave seal face and the dovetail groove seal face; the central position of the flange is provided with the main hole, the edge of the flange is provided with a double through bolt hole, and two objects are connected through the double through bolt hole; in the narrow space environment, and the connection of a pipeline, a gate valve and an equipment with different flange seal forms has convenience. The double-face flange has the advantages; 1. The large-sized drainage equipment mounted in the narrow space is possible; 2. A double-face flange is connected, a suite of double through bolt and a flange are saved, having compact link constructions.
Description
Technical field
The utility model relates to a kind of flange, particularly a kind of Double-face flange.
Background technique
At present, when the pipeline that connects identical flange seal form, gate valve or equipment, directly adopt and flange is coupled together get final product wearing bolt, when the pipeline that connects different flange seal forms, gate valve or equipment, common way is to increase by a joint short tube betwixt, at the different flange plate of the two ends of short tube welded seal form, by both being connected to wearing bolt.This Placement can only be used for the abundant environment in space, in the narrow and small environment in space, often is difficult to solve on-the-spot connectivity problem.
Summary of the invention
The purpose of this utility model is to provide a kind of in the narrow and small environment in space, and the pipeline that the adpting flange seal form is different, gate valve and equipment is Double-face flange easily.
The purpose of this utility model has been achieved in that a flange plate, is equipped with main aperture at the centre bit of flange plate, is evenly equipped with at the edge of flange plate wearing bolt hole, and an end face of flange plate is a male-female seal contact face, and the other end is the dovetail groove sealing surface.
Beneficial effect: owing to adopt such scheme, this flange plate adopts thick round plate, car is made the end face of flange of male-female seal contact face and dovetail groove sealing surface respectively in the steel plate both sides, centre bit at flange plate is equipped with main aperture, be evenly equipped with wearing bolt hole at the edge of flange plate, employing connects two objects to wearing bolt, can make things convenient for the different pipeline of adpting flange seal form, gate valve and equipment in the narrow and small environment in space.Reached the purpose of this utility model.Advantage: 1, solved in the narrow space of space and large-scale drainage equipment to be installed to become possibility; 2, adopt place's Double-face flange to connect, can save a cover wearing bolt and a flange, linkage structure compactness.
