A purpose of the present invention is to provide an orifice-nozzle-type, Venturi-nozzle-type, and tunnel-structure resistance-tube-type steam trap that is capable of responding to changes in drain drainage amount that accompany, among other things, fluctuations in the operational pressure differential between a steam trap inlet and outlet and is capable of responding to fluctuations in the amount of steam used as a result of the driving conditions of steam-using equipment, external factors due to the seasons, or the like. Another purpose of the present invention is to provide a strainer filter that eliminates the strength insufficiencies that accompany the miniaturization of a strainer screen for a steam trap of the abovementioned types, that maintains the form of the screen, that enables easy mounting/removal of the screen to/from the strainer, and for which cleaning of the screen and other maintenance are easy. The steam strap of the present invention is an orifice-nozzle-type, Venturi-nozzle-type, and tunnel-structure resistance-tube-type steam trap that has a drain drainage amount adjustment mechanism that is a piping structure in which the height difference between a drain of a Venturi nozzle and a drain system outer discharge outlet is variable. Further, the strainer filter of the present invention is provided with a support body that reinforces the rigidity of a screen that is mounted to a strainer, the support body being provided on the inner side and/or outer side of the screen. |
