Abstract
The invention belongs to the technical field of steam turbine appliances, in particular to a baffle plate for a steam turbine. The baffle plate for the steam turbine is characterized by comprising an upper plate and a lower plate, wherein the upper plate is shorter than the lower plate, and the distance between the upper plate and the left side of the lower plate in the width direction to the distance between the upper plate and the right side of the lower plate in the width direction is 7: 6; the section of the upper plate is rectangular, the upper part of the section of the lower plate is rectangular, the lower part of the section of the lower plate is trapezoid, the internal included angle at the left side of the trapezoid is 15 degrees and the internal included angle at the right side of the trapezoid is 20 degrees. The baffle plate disclosed by the invention has the beneficial effects that the mechanism is reasonable and the service time of the baffle plate can be well prolonged.
Description
Technical field
The invention belongs to steam turbine apparatus technical field, particularly relate to a kind of steam turbine dividing plate.
Background technique
Steam turbine is the rotary power machinery transformation of energy of steam being become mechanical work.Also known as steam turbine.Main prime mover being used as generating, also can the various pump of Direct driver, blower fan, compressor and propeller for vessels etc.The steam discharge of steam turbine or intermediate extraction can also be utilized to meet and to produce and heat supply needs in life.The dividing plate of current steam turbine is one block of sheet material, so be easy to when in use go wrong.Because the mechanism of design is unreasonable, be easy to when in use produce wearing and tearing, thus cause the rapid damage of dividing plate.
Summary of the invention
The object of the invention is to solve above-described technical problem, provide a kind of mechanism reasonable, can be good at the steam turbine dividing plate extending dividing plate service time, its technological scheme is as follows:
A kind of steam turbine dividing plate, it is characterized in that, described steam turbine dividing plate comprises upper plate and lower plate, and the width of described upper plate is less than lower plate, and the spacing of described upper plate on the left of width direction distance lower plate is 7:6 with the ratio apart from the spacing on the right side of lower plate; The cross section of described upper plate is a rectangular, and the top in the cross section of described lower plate is rectangular, and the bottom in the cross section of described lower plate is trapezoidal, and in described trapezoidal left side, angle is 15 degree, and in described trapezoidal right side, angle is 20 degree.
Optimal way is, described upper plate is heat insulation and wear resistance plate.
Steam turbine dividing plate provided by the invention, when in use, is divided into upper plate and lower plate whole dividing plate, thus makes dividing plate have better performance.Upper plate and lower plate make whole dividing plate be divided into two-part, and upper plate and lower plate have different functions.Upper plate is mainly used for wear resistance, prevents dividing plate from scrapping because of wearing and tearing.And the effect of lower plate is connected with the miscellaneous part of steam turbine, dividing plate and miscellaneous part are combined.And the setting of various data parameters between upper plate and lower plate, make dividing plate more meet the requirement of use.
Upper plate of the present invention is heat insulation and wear resistance plate.Thus make upper plate more have durability, extend its utility time.
The invention has the beneficial effects as follows: mechanism is reasonable, can be good at extending dividing plate service time.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is sectional view of the present invention.
Embodiment
Embodiment is illustrated below in conjunction with Fig. 1 and Fig. 2:
As depicted in figs. 1 and 2, a kind of steam turbine dividing plate, described steam turbine dividing plate comprises upper plate 1 and lower plate 2, and the width of described upper plate 1 is less than lower plate 2, and the spacing of described upper plate 1 on the left of width direction distance lower plate 2 is 7:6 with the ratio apart from the spacing on the right side of lower plate; The cross section of described upper plate 1 is a rectangular, and the top in the cross section of described lower plate 2 is rectangular, and the bottom in the cross section of described lower plate 2 is trapezoidal 3, and in the left side of described trapezoidal 3, angle 4 is 15 degree, and in described trapezoidal right side, angle 5 is 20 degree.
Optimal way is, described upper plate is heat insulation and wear resistance plate.
Steam turbine dividing plate provided by the invention, when in use, is divided into upper plate and lower plate whole dividing plate, thus makes dividing plate have better performance.Upper plate and lower plate make whole dividing plate be divided into two-part, and upper plate and lower plate have different functions.Upper plate is mainly used for wear resistance, prevents dividing plate from scrapping because of wearing and tearing.And the effect of lower plate is connected with the miscellaneous part of steam turbine, dividing plate and miscellaneous part are combined.And the setting of various data parameters between upper plate and lower plate, make dividing plate more meet the requirement of use.
Claims (2)
