Abstract

The utility model discloses a connecting bend for metallurgical water cooling pipe, comprising an elbow body(1), nozzles(2 and 3) which are connected with two parallel pipes and in the same diameter; wherein, the bending semidiameter of the elbow is 0.5 time of the outside diameter of the nozzle, the outer walls of the nozzles(2 and 3) are tangent with the centre of the elbow body(1). Because the bend has a simple structure, so the utility model has a low cost; and the bending semidiameter of the bend is 0.5 times of the outside diameter of the nozzle, guaranteeing the connected pipe fittings are capable of forming a calandria, and the pipe fittings have small clearances, thereby increasing the heat transfer efficiency of the metallurgy water cooling fitting, and reducing the welding cost.

Description

A kind of elbow that is used for the connection of metallurgical water cooling pipe

The utility model relates to a kind of elbow that is used to connect two parallel tubess, particularly a kind of elbow that is used for the connection of calandria metallurgical water cooling pipe fitting.

At present, what steel-smelting electric furnace was advanced in the metallurgy industry is to adopt calandria water-cooled part, and the connection between the calandria water-cooled part needs 180 ° of elbows.Existing elbow since bending radius more than or equal to 1 times of nominal diameter, in order to the parallel tubes that connects, spacing is big, is difficult to form desirable comb.

The purpose of this utility model is to overcome the deficiency of above-mentioned existing procucts, and a kind of novel elbow that the metallurgical water cooling pipe connects that is used for is provided.Make the pipe fitting of connection form standardized comb, the gap in the comb between each pipe is no more than 0.5 millimeter.

The purpose of this utility model is achieved in that a kind of elbow that the metallurgical water cooling pipe connects that is used for, by curved head body (1) and can connect with two parallel tubess and the mouth of pipe (2), the mouth of pipe (3) that diameter is identical constitute, wherein the elbow bending radius is 0.5 times of mouth of pipe external diameter, and the mouth of pipe (2) is tangent in curved head body (1) center with the outer wall of the mouth of pipe (3).

The utility model is compared with existing like product has following characteristics: because elbow structure is simple, so cost is lower; The elbow bending radius is 0.5 times of mouth of pipe external diameter, guaranteed that the pipe fitting that is connected can form comb, and the gap is little, thereby has improved the heat transfer efficiency of metallurgical water cooling spare, and reduced welding cost.

Further specify the utility model below in conjunction with drawings and Examples.

Fig. 1 is a plan view of the present utility model.

Fig. 2 is a plan view of the present utility model.

Fig. 3 is the A-A sectional view of Fig. 2.

This elbow is by curved head body 1 and can constitute with the mouth of pipe 2, the mouth of pipe 3 that two parallel tubess are connected and diameter is identical, and its special way is: the elbow bending radius is 0.5 times of described mouth of pipe external diameter.The mouth of pipe 2 is tangent in the center of curved head body 1 with the outer wall of the mouth of pipe 3.For example produce the elbow of 60 * 5 millimeters of ф, can select 40 * 5 millimeters of ф, material for use is the tubing of No. 20 steel, get its long 180 millimeters, go out the even and curved head body 1 identical of wall thickness with the pushing processes with former tube wall thickness, bending radius is 30 millimeters, the external diameter of the mouth of pipe 2, the mouth of pipe 3 is 60 millimeters, and two mouths of pipe are parallel to each other, and its outer wall is tangent in curved head body 1 center.

Claims

1, a kind of elbow that is used for the connection of metallurgical water cooling pipe, by curved head body (1) and can connect with two parallel tubess and the mouth of pipe (2), the mouth of pipe (3) that diameter is identical constitute, it is characterized in that: the elbow bending radius is 0.5 times of mouth of pipe external diameter, and the mouth of pipe (2) is tangent in curved head body (1) center with the outer wall of the mouth of pipe (3).
