Title: THREE-WAY VALVE FOR CONNECTING A WATER HEATING DEVICE
Abstract:
The invention relates to construction. The valve comprises a housing with an inlet pipe, an outlet pipe, a drainage pipe and a valved pipe, and a controllable valve assembly with a bushing, a stem and a valve disc. The inlet and outlet pipes are disposed on the same axis and are separated by a solid partition. The drainage pipe is disposed at a right angle to the aforesaid pipes and communicates with the cavity of the inlet pipe. The valved pipe is disposed perpendicular to the plane of the axes of the inlet, outlet and drainage pipes. The cavity of the drainage pipe communicates via an opening with the cavity of the inlet pipe, and via a channel with the cavity of the outlet pipe. The minimum cross-sectional area of said channel and likewise the cross-sectional area of the aforementioned opening are less than the cross-sectional area of the opening that connects the cavity of the inlet pipe to the cavity of the valved pipe. The technical result is an increase in the range of means for smoothly adjusting the temperature intensity of a heating device connected to a single-pipe heating system, as well as an increase in reliability both in operation and during the start-up stage.
