Title: Negative pressure breaking device
Inventor: HAMADA MAKOTO
IPC: F16K31/524
Filed: 2002-02-06
Abstract: <P>PROBLEM TO BE SOLVED: To surely prevent generation of a backflow from the storage tank side even if operational abnormality and power failure are caused.  <P>SOLUTION: Hot water pouring solenoid valves 62 and 64 are interposed on the respective upstream-downstream sides of a hot water pouring passage 50 for pouring hot water into a bathtub by branching off from a hot water supply circuit 2. A pressure cancel valve 67, a sub-opening-closing directional control valve 63, and a negative pressure breaking valve 66 are arranged between both. These valves are joined to a valve stem 68 advanced via an electric motor 69 and a cam member 70, and retreated by a return spring 71. When advancing the valve stem, the sub-opening-closing directional control valve opens, and the negative pressure breaking valve closes, and is put in a hot water pouring state. When retreating the valve stem, the sub-opening- closing valve closes, and the negative pressure breaking valve opens, and is put in a steady state. Even if closing operation abnormality is caused in the whole valves in the steady state, when negative pressure is generated on the upstream side, air is instantly sucked in from a negative pressure breaking valve-atmospheric opening port 663 of a valve opening state, and the negative pressure is eliminated to check the backflow. Operational resistance of the sub-opening-closing valve is cancelled by the pressure cancel valve so that the valve stem can be driven by light operation torque and a small rotation quantity.  <P>COPYRIGHT: (C)2003,JPO
