Abstract

A welding elbow with a guide plate mounted inside relates to a welding elbow used in a marine steam turbine cylinder edge communication device and aims to solve the problem that heat loss is increased because the guide plate is arranged in the middle of the inner part of the welding elbow in the conventional marine steam turbine cylinder edge communication device. The welding elbow comprises an elbow body and the guide plate; the guide plate is mounted in the elbow body; the guide plate is fixedly connected to the inner wall of the elbow body; the ratio of the distance between the guide plate and the inner wall with small bending radius of the elbow body and the drift diameter of the elbow body is 0.32 to 0.34; and the center of the bending radius of the guide plate coincides with that of the bending radius of the elbow body. The welding elbow provided by the utility model is used in the marine steam turbine cylinder edge communication device.

Description

The weld ell of guide plate is equipped with in a kind of inside
Technical field
The utility model relates to a kind of weld ell that is used for boats and ships steam turbine cylinder border communication apparatus.
Background technique
High-temperature steam enters another cylinder through existing boats and ships steam turbine cylinder border communication apparatus from a cylinder, wherein will experience twice right angle turnover.Usually the implementation method of right angle turnover has: 1, adopt elbow, do not add guide plate; 2, adopt louver vane; 3, adopt elbow, in the middle of guide plate is added in.Louver vane owing to additionally increased more resistance piece, needs cautiously during application, design well, just can reduce thermal loss, otherwise increase loss on the contrary, and middle guide plate has the risk that flutter takes place, and the installation complexity is unfavorable for promoting; Studies show that single guide plate is added in the middle of the elbow, can make the total thermal loss of device reduce by 4%; Two uniform being added in the middle of the elbow of guide plate are installed total thermal loss reduction and are had only 0.8% on the contrary; For taking which kind of measure could further reduce the device loss in elbow, industry is unified view.
The model utility content
The purpose of this utility model provides the weld ell that guide plate is equipped with in a kind of inside, and higher to solve the present boats and ships steam turbine cylinder border communication apparatus pressure loss, bend loss accounts for the problem of very big proportion.
The utility model is to solve the problems of the technologies described above the technological scheme of taking to be: described weld ell comprises elbow body and guide plate, described guide plate is contained in the elbow body, and the inwall of guide plate and elbow body is affixed, distance between the small-bend radius inwall of guide plate and elbow body is 0.32-0.34 with the ratio of the latus rectum of elbow body, and the bending radius center of guide plate overlaps with the bending radius center of elbow body.
The utlity model has following beneficial effect: the utility model has been eliminated the eddy current loss after the right angle turnover greatly, has improved flowing of elbow, can make the device total losses reduce by 7%, and Security is good, and installation is simple.In the every profession and trade of modern society, channel bend extensively adopts as bare bones, and no matter hot-pressed elbow or weld ell all can be by the utility model requirement mounting guiding board.Because guide plate only in the elbow, limited space is little, is convenient to producer and implements, in case extensively adopt in fluid circuit, will help improving the using energy source level of entire society.
Description of drawings
Fig. 1 is an overall structure plan view of the present utility model.
Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1, the weld ell of present embodiment comprises elbow body 1 and guide plate 2, described guide plate 2 is contained in the elbow body 1, and guide plate 2 is affixed with the inwall of elbow body 1, the ratio that it is characterized in that the latus rectum φ of distance L between the small-bend radius inwall of guide plate 2 and elbow body 1 and elbow body 1 is 0.32-0.34, and the bending radius center of guide plate 2 overlaps with the bending radius center of elbow body 1.
Embodiment two: in conjunction with Fig. 1 present embodiment is described, the guide plate 2 of present embodiment is welding with the affixed form of inwall of elbow body 1, and this structure is easy for installation can not rosin joint.Other compositions and annexation are identical with embodiment one.
