Abstract
The utility model relates to a static-pressure measuring hole anti-plugging device for a power plant boiler smoke system. The device comprises a smoke channel pipe wall of a power plant boiler smoke channel, a plugging needle base fixedly arranged on the smoke channel pipe, a static-pressure measuring hole formed in the middle of the smoke channel pipe wall and plugging needle base and a plugging needle arranged in the static-pressure measuring hole in a penetrating manner. The diameter of the middle-upper portion of the static-pressure measuring hole is larger than that of the lower portion of the static-pressure measuring hole. A plug is fixedly arranged on the upper portion of the plugging needle and is connected to the inner side of the end of the static-pressure measuring hole in a screwed manner, the plugging needle is arranged in the static-pressure measuring hole so that the static-pressure measuring hole can be prevented from being plugged by dust in the flow in the pipeline, and the plug is connected to the static-pressure measuring hole in a screwed manner so that the plugging needle can be taken out from the static-pressure measuring hole conveniently and the static pressure in the pipeline can be measured conveniently. The device is simple in structure and convenient to use, and on-site operating efficiency is improved.
Description
Technical field
The utility model relates to a kind of static opening anti-block apparatus for station boiler air and gas system.
Background technology
The structure of tube wall pressure gaging hole while having specified measuring channel cross section static pressure in DL/T 469-2004 " test of For Air Fans of Utility Boilers field performance ", specific requirement is: inner surface of pipeline and bore edges should be smooth without burr, baroport is perpendicular to cigarette, air channel tube wall, and baroport diameter is got 2~4mm.When working medium is cold air, baroport connecting pipe length is got 50mm; When working medium is hot-air or flue gas, connecting pipe length is got 200mm.Because baroport diameter is very little, and in actual production owing to containing a large amount of dust in chimneying, there is blocked phenomenon in most of tube wall pressure gaging holes after equipment operation a period of time, has a strong impact on work on the spot.
Utility model content
Problem to be solved in the utility model is to provide the blocking-proof static pressure gaging hole plug of static opening in a kind of station boiler air and gas system that prevents static opening obstruction.
The utility model adopts following technical scheme:
The utility model comprise station boiler flue flue tube wall, be fixedly installed on stifled pin pedestal on flue tube wall, be arranged on the static opening at flue tube wall and stifled pin pedestal middle part and run through the stifled pin being arranged in static opening, aperture, described static opening middle and upper part is greater than the aperture of bottom, described stifled pin top is fixedly installed plug, and described plug is connected with static opening end inside thread.
The utility model good effect is as follows:
The utility model arranges stifled pin in static opening, can prevent that static opening from not stopped up by the dust in chimneying, and plug is threaded with static opening, can conveniently in static opening, take out stifled pin, and easily the static pressure in pipeline be measured.Stifled pin pedestal is convenient to adopt resilient emulsion tube will block up pin pedestal to be connected with static pressure measurement instrument on the one hand; The length that can increase on the other hand static opening after the stifled pin pedestal of installation, meets standard-required.Aperture, static opening middle and upper part is greater than the impact that can play the fluctuation of buffering pipe internal pressure in aperture, bottom, and the fluctuation of static pressure while slackening static pressure measurement, is more conducive to obtain static pressure measurement value accurately.The utility model is simple in structure, easy to use, has improved on-the-spot operating efficiency.
Brief description of the drawings
Accompanying drawing 1 is the utility model structural representation.
In the accompanying drawings: 1 flue tube wall, 2 stifled pin pedestals, 3 static openings, 4 stifled pins, 5 plugs.
Detailed description of the invention
As shown in Figure 1, the utility model comprise station boiler flue flue tube wall 1, be fixedly installed on stifled pin pedestal 2 on flue tube wall 1, be arranged on the static opening 3 at flue tube wall 1 and stifled pin pedestal 2 middle parts and run through the stifled pin 4 being arranged in static opening 3, described static opening 3 apertures, middle and upper part are greater than the aperture of bottom, described stifled pin 4 tops are fixedly installed plug 5, and described plug 5 is connected with static opening 3 end inside threads.
When work, will take off with the plug 5 of stifled pin 4, with elastic emulsion tube connection pressure measurement instrument and stifled pin pedestal 2, can carry out the static pressure measurement in flue.
The utility model arranges stifled pin in static opening, can prevent that static opening 3 from not stopped up by the dust in chimneying, and plug 5 is threaded with static opening 3, can conveniently in static opening, take out stifled pin 4, and easily the static pressure in pipeline be measured; Stifled pin pedestal 2 is convenient to adopt resilient emulsion tube will block up pin pedestal 2 to be connected with static pressure measurement instrument on the one hand; On the other hand owing to requiring the height of static opening on flue tube wall to be greater than the diameter of the static opening of twice in DL/T 469-2004 " test of For Air Fans of Utility Boilers field performance " standard, and in actual applications because flue tube wall is thinner, can not reach standard, the height that can increase static opening after the stifled pin pedestal 2 of employing, the height that meets static opening is greater than the requirement of the static opening diameter of twice; Aperture, static opening middle and upper part is greater than aperture, bottom can play the impact that buffering pipe internal pressure fluctuates, and the fluctuation of static pressure while slackening static pressure measurement, is more conducive to obtain static pressure measurement value accurately.The utility model is simple in structure, easy to use, has improved on-the-spot operating efficiency.
