Abstract
The invention discloses a welding elbow with built-in deflector and relates to a welding elbow in an inter-cylinder communicating device of a steam turbine of a ship. The problem that the arrangement of the deflector in the welding elbow in the inter-cylinder communicating device of the steam turbine of the ship increases the heat loss in the prior art is solved. The welding elbow comprises an elbow main body and the deflector, wherein the deflector is arranged in the elbow main body; the deflector is fixedly connected with the inner wall of the elbow main body; the ratio of the distance between the deflector and the small-bending-radius inner wall of the elbow main body to the drift diameter of the elbow main body ranges from 0.32 to 0.34; and the center of the bending radius of the deflector and the center of the bending radius of the elbow main body are superposed. The welding elbow is applied in the inter-cylinder connecting device of the steam turbine of the ship.
Description
Technical field
The present invention relates to a kind of weld ell for cylinder edge communicating device for ship steam turbines.
Background technique
High-temperature steam enters another cylinder through existing cylinder edge communicating device for ship steam turbines from a cylinder, wherein will experience twice right angle turnover.Conventionally 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 having 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 occurs, and installation is complicated, is unfavorable for promoting; Research shows, single guide plate is added in the middle of elbow, can make the total thermal loss of device reduce by 4%; Two uniform being added in the middle of elbow of guide plate, install total thermal loss reduction and only have on the contrary 0.8%; For taking which kind of measure could further reduce device loss in elbow, the ununified view of industry.
Summary of the invention
The object of this invention is to provide a kind of inside the weld ell of guide plate is housed, higher to solve the current cylinder edge communicating device for ship steam turbines pressure loss, bend loss accounts for the problem of very large proportion.
The present invention solves 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 elbow body, and the inwall of guide plate and elbow body is affixed, the ratio of the distance between the small-bend radius inwall of guide plate and elbow body and the latus rectum of elbow body is 0.32-0.34, the bending radius center of guide plate and the bending radius center superposition of elbow body.
The present invention has following beneficial effect: the present invention has eliminated the eddy current loss after right angle turnover greatly, has improved flowing of elbow, can make 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 requirement mounting guiding board of the present invention.Due to a guide plate only in elbow, limited space is little, is convenient to producer and implements, once extensively adopt in fluid circuit, will be conducive to improve the using energy source level of entire society.
Accompanying drawing explanation
Fig. 1 is overall structure plan view of the present invention.
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 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 guide plate 2 and the small-bend radius inwall of elbow body 1 and elbow body 1 is 0.32-0.34, the bending radius center of guide plate 2 and the bending radius center superposition 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.
