Abstract
A deaerated water nozzle of a steam temperature and pressure reducer comprises a nozzle base body and is mainly and technically characterized in that a nozzle sliding rod is arranged in a central cavity of the nozzle base body, a far nozzle end of the nozzle sliding rod is connected with a pressure spring, the pressure spring is fixed by a spiral cover cap, and a nozzle cock is arranged at a position, close to a nozzle, of the nozzle sliding rod. The steam flow velocity of the throat part of the Venturi tube is always in a high-speed state, and the desuperheating water is immediately crushed by the high-speed steam after passing through the spring adjustable nozzle, so that a good atomization effect is ensured. After the cooling water is sprayed out at the flow speed of 18-23 m/s through the spring adjustable nozzle, the cooling water is driven by high-speed steam to achieve rapid atomization. The nozzle has the characteristics of low noise and large adjusting range, has good atomizing effect when reducing temperature within the range of 10-100% rated output, avoids the bad working conditions of water hammer, cavitation erosion and the like, stably operates for a long time, and is safe and reliable.
Description
Technical Field
The utility model relates to a nozzle of setting in venturi mixing tube throat.
Background
The nozzle is arranged at the throat part of the Venturi mixing pipeline, the former nozzle is a nozzle, cannot be adjusted, and the atomization effect is not ideal.
Disclosure of Invention
The utility model provides a steam temperature-reducing pressure reducer deoxidization water nozzle which has large adjusting range and good atomization effect during temperature reduction.
The utility model discloses a realize through following technical scheme: a deaerated water nozzle of a steam temperature and pressure reducer comprises a nozzle base body and is mainly and technically characterized in that a nozzle sliding rod is arranged in a central cavity of the nozzle base body, a far nozzle end of the nozzle sliding rod is connected with a pressure spring, the pressure spring is fixed by a spiral cover cap, and a nozzle cock is arranged at a position, close to a nozzle, of the nozzle sliding rod.
The nozzle of the deoxygenation water nozzle is provided with annular spray holes which are respectively connected with a rotational flow cavity.
The deaerating water nozzle is placed at an angle of 45 degrees away from the center line.
The spring adjustable nozzle (with 3mm of spray holes) is arranged at the throat part of the Venturi mixing pipeline, and the temperature reduction is realized by directly spraying atomized water and steam through the spring adjustable nozzle arranged at the throat part of the Venturi mixing pipeline. The steam flow velocity of the throat part of the Venturi tube is always in a high-speed state, and the desuperheating water is immediately crushed by the high-speed steam after passing through the spring adjustable nozzle, so that a good atomization effect is ensured. After the cooling water is sprayed out at the flow speed of 18-23 m/s through the spring adjustable nozzle, the cooling water is driven by high-speed steam to achieve rapid atomization. The nozzle has the characteristics of low noise and large adjusting range, has good atomizing effect when reducing temperature within the range of 10-100% rated output, avoids the bad working conditions of water hammer, cavitation erosion and the like, stably operates for a long time, and is safe and reliable.
Description of the drawings:
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the placement of the nozzles.
The specific implementation mode is as follows:
as shown in figures 1 and 2, the deaerating water nozzle of the steam temperature and pressure reducer comprises a nozzle base body 1, a nozzle sliding rod 2 is arranged in a central cavity of the nozzle base body 1, a far nozzle end of the nozzle sliding rod is connected with a pressure spring 3, the pressure spring is fixed by a spiral cover cap 4, and a nozzle cock 5 is arranged at a position, close to a nozzle, of the nozzle sliding rod. The nozzle of the deoxygenated water nozzle is provided with annular spray holes 6 which are respectively connected with a rotational flow cavity 7. The cyclone cavity 7 is connected with 8 cyclone type fluid channels 8, and the spiral cover cap is fixed on the nozzle base body by a pin 9. The nozzle is connected with a water gun 10, and the deaerated water nozzle deviates 45 degrees from the central line.
The spring adjustable nozzle is arranged at the throat part of the Venturi mixing pipeline, the temperature reduction is realized by a mode of directly spraying atomized water and steam through the spring adjustable nozzle arranged at the throat part of the Venturi mixing pipeline, and the main technical characteristic is that the spray holes deviate from the central line by 45 degrees. The steam flow velocity of the throat part of the Venturi tube is always in a high-speed state, and the desuperheating water is immediately crushed by the high-speed steam after passing through the spring adjustable nozzle, so that a good atomization effect is ensured. After the cooling water is sprayed out at the flow speed of 18-23 m/s through the spring adjustable nozzle, the cooling water is driven by high-speed steam to achieve rapid atomization. The nozzle has the characteristics of low noise and large adjusting range, has good atomizing effect when reducing temperature within the range of 10-100% rated output, avoids the bad working conditions of water hammer, cavitation erosion and the like, stably operates for a long time, and is safe and reliable.
