摘要： A valve ring arrangement is disclosed in which the corrosion sensitive parts of shut-off valves, control valves and condensate-removal devices are kept out of contact with condensate accumulations. Also disclosed are float and bucket-type condensate-removal devices which are protected against shutdown corrosion by means of automatically draining them during shutdowns.

摘要： This invention pertains to a float and thermostatic steam trap with an improved mechanism less subject to failure than previous designs. In this design the venting and trapping functions are served by the same valve and a thermostatic actuator acts on the float or float linkage when temperature is below a predetermined value. In normal operation the float controls the discharge of condensate and the thermostatic actuator is out of contact with the float assembly and therefore is free to move. When the temperature within the trap housing drops below the predetermined value, the thermostatic actuator engages the float assembly, forces the valve opening and raises the float above the condensate level. This allows the removal of condensate and of the noncondensible gasses from the trap. This design eliminates the stressing of the thermostatic actuator by static or vibration loads at high temperatures and thereby reduces the fatigue failure of the actuator. At the same time, as the float is raised out of the water, the water level is lowered or completely drained, thereby reducing corrosion exposure during shutdown. In the embodiments wherein the housing is completely drained by the thermostatic actuator frost protection is provided and the accumulation of solids within the housing is prevented by flushing action.
摘要翻译：本发明涉及一种浮动和恒温蒸汽疏水阀，其具有比以前的设计更少受到故障的改进的机构。在这种设计中，通风和捕集功能由相同的阀提供，当温度低于预定值时，恒温致动器作用在浮子或浮子连杆上。在正常操作中，浮子控制冷凝水的排放，恒温致动器与浮子组件脱离接触，因此可以自由移动。当捕集器壳体内的温度低于预定值时，恒温致动器接合浮子组件，迫使阀门开启并将浮子升高到冷凝液水平面上方。这样可以将冷凝物和不凝气体从捕集器中去除。该设计消除了在高温下的静态或振动负载对恒温致动器的应力，从而减少了致动器的疲劳失效。同时，当浮子从水中升出时，水位下降或完全排水，从而减少停机时的腐蚀暴露。在壳体被恒温致动器完全排出的实施例中，提供了防霜保护，并通过冲洗动作来防止壳体内的固体积聚。

摘要： A luminaire provided with an inflatable gasket for airtight and dustproof sealing of its interior and for simultaneously gripping the cover of the luminaire in closed position while the gasket is inflated. The sealing forces act in a plane which is essentially perpendicular to the plane of symmetry of the cover. Untight closure of the cover is signaled by the visible displacement of the cover in case of deflation of the gasket.
