Title: Pressure reducing valve
Inventor: IWAMOTO HOMARE
IPC: G05D16/00
Filed: 2001-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent water leakage in case of the damage of a diaphragm. SOLUTION: In this pressure reducing valve 1, a spring chamber 4 provided closed with a spring cover 3 and a diaphragm 13 receiving secondary side pressure, and an atmospheric pressure chamber provided in the spring chamber 4, communicating with the outside, are airtightly partitioned by a pressure- displacement conversion element 16 formed of a bellows. In normal use, the pressure-displacement conversion element 16 is thereby displaced onto the spring chamber 4 side or the atmospheric pressure chamber 5 side according to the pressure in the spring chamber fluctuating due to temperature change in the spring chamber 4. The volume of the spring chamber 4 is thereby expanded or contracted to hold the pressure in the spring chamber always constant.  As a result, the pressure reducing valve 1 functions without hindrance without applying the pressure in the spring chamber to the diaphragm 13 to press in a valve opening direction. Even in case the diaphragm 13 is damaged to cause pressurized water to flow into the spring chamber 4 from a secondary side pressure chamber 9, water leakage is prevented by the airtightness of the spring chamber 4.
