[0001] STEAM TRAP OF MULTIPLE NOZZLE-ORIFICES [0002]

[0001] The present invention relates to a multiple nozzle orifice steam trap, and more particularly, to an orifice having multiple nozzles hinged to prevent the backflow of condensed water, discharge pressure control, and steam discharge Orifice < / RTI > steam trap.

In the piping pipes for steam (steam) in the production facilities using steam (steam, steam), heat exchanger and steam piping facilities, the temperature difference between the inside and the outside of the piping is large due to the high temperature and high pressure steam. It is very common that condensation water or condensation water is generated in the transfer pipe due to the temperature difference.

Such condensed water is moved along with the steam along the steam transfer path, and the steam transfer pipe hits the steam transfer pipe to cause a lot of noise in the steam transfer pipe, which causes a water hammer and causes a decrease in heat efficiency. SteamGard or steam trap may be installed on the steam transfer pipe to remove condensate.

The steam trap automatically discharges the condensate of the steam transfer pipe to the outside of the steam transfer pipe, and various techniques such as the ball float method, the disk method, the bimetal method, the bucket method, and the orifice method are introduced and used.

The ball float type steam trap is a system that automatically discharges condensate to the outside of the steam transfer pipe by using the density difference between steam and condensate. It is not affected greatly by sudden fluctuation of pressure and flow rate, but it causes damage due to freezing .

The disc type steam trap is operated in such a manner that when the condensed water rises in the corresponding steam trap, the internal temperature of the steam trap is lowered and the pressure in the transforming room is lowered, so that the disc is lifted and the condensed water is automatically discharged to the outside.

The bimetal type steam trap is designed such that when the condensed water flows into the corresponding steam trap, the internal temperature of the steam trap is lowered and the bimetal acts, so that the ball valve is opened and the condensed water is discharged to the outside.

Here, the bimetal of the bimetallic steam trap is made of two kinds of metals having different coefficients of thermal expansion, and is bent by the temperature change.

A bucket type steam trap is a method in which a bucket floats to close (close) a drain valve. When condensate flows from an inlet to a drain, the bucket of the drain sinks and the drain valve directly connected to the bucket opens. And the condensate in the bucket is discharged to the outside through the drain.

Of these steam traps, the orifice method has an advantage of minimizing leakage of steam, eliminating the need for an operating structure, having a small heat generating area, and improving the heat transfer coefficient to the heating body.

However, since the orifice type steam trap of the related art as described above discharges condensed water and discharges steam together, the utilization efficiency of heat energy or steam energy is comparatively low, and thus the productivity of the production equipment using steam is lowered, There is a problem that it does not greatly contribute to growth and low carbon generation.

Therefore, it is necessary to develop a technology to reduce the discharge of steam from the orifice and to discharge only condensate.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art, and it is an object of the present invention to provide a nozzle having a plurality of nozzles hinged to an orifice and capable of easily controlling the interval of multiple nozzles, It is intended to provide an orifice steam trap.

In the present invention, it is preferable that a filtering net is disposed in front of the front nozzle.

In the present invention, it is preferable that the control groove provided in the multiple nozzles is provided as a straight line, a cross or a hexagonal groove.

The multi-nozzle orifice steam trap according to the present invention has an excellent effect that clogging of the front nozzle and the multiple nozzles is not caused by the foreign substance because the foreign substances discharged as the condensed water are double removed.

Also, since the condensed water discharged through the front nozzle passes through a plurality of multiple nozzles coupled to the flow path, and the steam flowing as condensed water is condensed by the space of the multiple nozzles, the steam can be prevented from being exposed, which is an excellent effect .
