Title: Freezing preventing valve body in various valves
Inventor: KATAYAMA MORIHIRO
IPC: F17D1/05
Filed: 1984-10-03
Abstract: PURPOSE:To prevent freezing of a pipe during winter season, by a method wherein, when the temperature of the open air is decreased, water is caused to flow by making it automatically leak in keeping a condition to close a valve. CONSTITUTION:A chamber 4, sealed with liquid and gas, is formed in a valve body, and a cylinder hole 5 communicated with the chamber 4 is provided. A piston 8 is inserted into the cylinder hole 5, and the piston 8 is pressurized in the direction of liquid and gas through the force of a spring 9. Leak holes 6, communicated with the flow-in side and the flow-out side in a valve box and mutually closed by a valve body, are open to the valve body, the communication is shut off by the piston 8. This constitution, when the temperature of the open air is decreased, causes movement of the piston 8 through contraction of the sealed liquid and gas, causes the water leak holes 6 to be communicated with each other, and causes water in the flow-in chamber in the valve box to flow in small quantities in a flow-out chamber, resulting in the possibility to prevent freezing of a pipe.
