Description
Technical Field
The invention relates to a pore plate device, in particular to an adjustable plug-type pore plate.
Background
The nuclear power plant has a large number of important steam pipelines, wherein saturated steam is operated, the steam forms a small amount of condensed water during operation, the condensed water needs to be discharged in real time, otherwise the quality of the steam is affected, therefore, a special orifice plate is arranged in the pipeline and used for discharging the condensed water, and meanwhile, in the case of no condensed water, the orifice plate is needed to limit the steam to flow out, and the accuracy of the throttling flow is achieved.
Therefore, there is a particular need for an adjustable plug orifice plate that addresses the above-identified problems.
Disclosure of Invention
The invention aims to provide an adjustable plug-type pore plate which can discharge condensed water in a steam pipeline of a nuclear power plant in real time and limit the discharge of steam aiming at the defects of the prior art, so that a throttling effect with certain precision is achieved.
The technical problem solved by the invention can be realized by adopting the following technical scheme:
the adjustable plug-type pore plate is characterized by comprising a shell, wherein an adjusting sleeve is arranged in the shell, a cylindrical pore plate is arranged in the adjusting sleeve, and a gland is arranged on the side surface of the shell.
In one embodiment of the invention, the adjusting sleeve is of a double-adjusting cylindrical sleeve structure with internal threads and external threads, the diameters of the front and rear cylindrical sleeves are different, and the middle through hole is placed in the orifice plate.
In one embodiment of the invention, the cylindrical hole plate is provided with a cylindrical plug structure with external adjusting threads, a certain number of through holes are symmetrically or asymmetrically formed in the circumferential direction of the cylindrical surface, non-through holes are axially formed, and the two parts of the through holes are communicated.
In one embodiment of the invention, the aperture of the holes on the cylindrical hole plate is 0.5-10 mm.
In one embodiment of the invention, the shape of the holes of the cylindrical hole plate is circular.
Compared with the prior art, the adjustable plug-type pore plate can be combined with the cylindrical pore plate through the adjusting sleeve
The precision requirement under the requirement of the circulation capacity is realized by adjusting, the field adjustment is convenient, the working condition parameters can be adjusted on site after being changed, the structure is simple, the reliability is high, and the purpose of the invention is realized.
The features of the present invention will be apparent from the accompanying drawings and from the detailed description of the preferred embodiments which follows.
Drawings
FIG. 1 is a schematic diagram of an adjustable plug-type orifice plate according to the present invention.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.
Examples
As shown in FIG. 1, the adjustable plug-type orifice plate of the present invention comprises a housing 10, an adjusting sleeve 20 disposed in the housing 10, a cylindrical orifice plate 30 disposed in the adjusting sleeve 20, and a gland 40 disposed on a side surface of the housing 10.
In this embodiment, the adjusting sleeve 20 has a double-adjusting cylindrical sleeve structure with internal and external threads, the diameters of the front and rear cylindrical sleeves are different, and the hole plate is placed in the middle through hole.
In this embodiment, the cylindrical hole plate 30 has a cylindrical plug structure with an external adjusting thread, a certain number of through holes are symmetrically or asymmetrically formed in the circumferential direction of the cylindrical surface, non-through holes are axially formed, and the two parts of the through holes are communicated with each other.
In this embodiment, the diameter of the holes of the cylindrical orifice plate 30 is 0.5 to 10 mm.
In this embodiment, the shape of the holes of the cylindrical hole plate 30 is circular.
The cylindrical orifice plate 30 provides a small flow passage to realize the throttling control with certain precision, the adjusting sleeve 20 provides a large flow passage to realize the adjustment of large-range working conditions, and the large-range and small-range accurate adjustment of design consideration can be realized through the combined adjustment of the two.
When only a small flow range is needed, the adjusting sleeve 20 is turned right to be closed, and the cylindrical orifice plate 30 is turned left to be opened, so that the small-opening is realized; the cylindrical orifice plate 30 is rotated to the right, gradually closing the passages and eventually all the passages.
When a large flow range is needed, the adjusting sleeve 20 needs to be rotated leftwards to be opened, and the cylindrical orifice plate 30 can be correspondingly adjusted and rotated according to actual conditions.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined by the appended claims and their equivalents.
