Abstract

PURPOSE: To intermediately set a device between a condenser and evaporation in a refrigeration system and use the device as a constant pressure expansion valve, by setting fluid pressure at the secondary side of a valve with adjustement of an external load.
CONSTITUTION: When this valve device A is set in a refrigeration system, a residual coolant (R-12) in an evaporator E during the stopping of a compressor B shows pressure equivalent to environmental temperature (for instance, 20°C) to become pressure higher than P2(for instance, 4.3kg/cm2G), then a valve body 10 firmly closes a valve seat 9a. Under this condition if the compressor B is started, the coolant in a secondary side is sucked by the compressor B to lower its pressure because the valve body 10 is closed, and if the P2 becomes not higher than 4.2kg/cm2G, the valve is opened by the initial load of bimetal plates 5, 6, and the coolant begins to flow. The coolant flows, and if the secondary side pressure P2 becomes 4.2kg/cm2G, the valve body is closed, accordingly the secondary side pressure P2 is never raised to at least 4.2kg/cm2G.
