Title: Valve for emptying boilers
IPC: F16K11/16
Filed: 1970-07-11
Abstract: A valve for emptying boilers has a locking member for the liquid phase and a locking member for the gas phase, the two members being coaxial and being operated by a common actuating device against the action of closing springs. The locking member for the liquid cooperates with a valve seat fixed to the bottom of the boiler. The valve is particularly characterized in that the locking member for the liquid is provided with a central flow passage for the gas phase. A fixed tube joint for gas flow is seal tightly connected to the passage from the boiler interior. A fixed tube joint for gas outflow is also connected from the outside to the passage. The two points permit a relative movement of the locking member for the liquid. The locking member for the gas is located in this passage.
