Description

Flange casting structure

Technical Field

The utility model relates to a flange casting especially relates to a flange casting structure that gas tightness required height.

Background

A flange, also known as a flange collar or flange. Flanges are parts of the interconnection between shafts for the connection between pipe ends. 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. When the water pump and the valve are connected with a pipeline, the parts of the equipment and equipment are also made into corresponding flange shapes, which are also called flange connection. The connecting parts which are connected by using bolts at the peripheries of two planes and are closed at the same time are generally called flanges, and for example, the connecting parts of the ventilating duct can be called flange parts.

I have now designed a new flange casting structure for connect a plurality of pipe ends, and have certain contained angle between a plurality of pipe ends. It is also required that the airtightness between the joined pipe ends is good. At present, no adaptive flange casting is found in the market, and in order to solve the problems, a flange casting is independently researched and designed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a flange casting structure is provided, connect many pipe ends, and the gas tightness is good.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a flange casting structure, is including the flange seat of seting up the mounting hole, the flange seat on be provided with the main pipe spare of crooked tubular structure, main pipe spare and mounting hole intercommunication, a side of main pipe spare set up a pipe fitting, branch pipe spare slope set up in flange seat top, the one end of a pipe spare stretch into main pipe spare lateral wall and switch on with main pipe spare, the other end edge and the flange seat of a pipe spare be connected, the outer peripheral face of a pipe spare extend to and be connected with main pipe spare outer peripheral face, flange seat, main pipe spare, branch pipe spare integrated into one piece.

The utility model discloses further preferred scheme: the flange seat be tetragonal piece dress structure, the edge of flange seat be mellow arc chamfer.

The utility model discloses further preferred scheme: the main pipe member is bent toward one side of the branch pipe member.

The utility model discloses further preferred scheme: an included angle is formed between the planes of the branch pipe fittings and the main pipe fittings.

The utility model discloses further preferred scheme: the inner hole of the branch pipe fitting is a stepped hole.

The utility model discloses further preferred scheme: the flange seat is provided with two fixing holes which are positioned at two sides of the mounting hole.

The utility model discloses further preferred scheme: the edge of the fixing hole extends upwards to form a structural reinforcing ring.

Compared with the prior art, the utility model has the advantages of set up the main pipe fitting and communicate the pipe fitting of main pipe fitting, constitute the flange foundry goods of connecting many pipe ends. The main pipe fitting is of a bent tubular structure, the branch pipe fitting is of a straight pipe structure and is arranged obliquely relative to the flange seat, and the installation requirement is met by the oblique arrangement relative to the main pipe fitting. And the branch pipe fittings are communicated to the side wall surfaces of the main pipe fittings, so that the air tightness is good. The outer peripheral face of this outer support pipe fitting and main pipe fitting links into an organic whole, makes the utility model discloses a structural strength is high and the shaping degree of difficulty is low.
