摘要： An object of the present invention is to provide an orifice nozzle-type steam trap, a Venturi nozzle-type steam trap, and a tunnel-structured resistance tube-type steam trap capable of coping with a change in the discharged amount of drain due to, for example, a variation in the amount of steam used resulting from the operating condition of steam-based equipment, seasonal external factors or a variation in the working pressure difference between the inlet and outlet of a steam trap. Another object of the present invention is to provide a strainer filter that eliminates strength insufficiency due to the miniaturization of strainer screens of these nozzle-type steam traps, retains the forms of the screens, allows the screens to be easily attached to and detached from the strainers, and makes maintenance, such as screen cleaning, easy. The orifice nozzle-type, Venturi nozzle-type, and tunnel-structured resistance tube-type steam traps of the present invention include a drainage volume adjusting mechanism which is a piping structure in which the height difference between the drain vent and the non-drain system vent of a Venturi nozzle is variable. In addition, in the strainer filter of the present invention, a support body for reinforcing the rigidity of a screen attached to a strainer is disposed on the inner side and/or the outer side of the screen.
摘要翻译：本发明的目的在于提供一种孔型喷嘴式蒸汽疏水阀，文丘里喷嘴式蒸汽疏水阀以及隧道式电阻管式蒸汽疏水阀，其能够应对由例如，由于蒸汽设备的操作条件，季节性外部因素或蒸汽疏水阀的入口和出口之间的工作压差的变化而导致的蒸汽使用量的变化。本发明的另一个目的是提供一种滤网过滤器，该滤网过滤器消除了由于这些喷嘴式疏水阀的滤网的小型化而导致的强度不足，保持了滤网的形式，允许滤网容易地附着到过滤器，并使维护，如屏幕清洁，容易。本发明的节流喷嘴式，文丘里喷嘴式和隧道式电阻管式蒸汽疏水阀包括排水量调节机构，该排水量调节机构是管道结构，其中排水口和非排水口之间的高度差文丘里喷嘴的系统通风口是可变的。另外，在本发明的过滤器中，用于增强附接到过滤器的筛网的刚度的支撑体布置在筛网的内侧和/或外侧。
