Abstract: A method for handling a substance from which a combustible gas volatilizes. A method for handling a substance from which a combustible gas volatilizes, in which, when such substance is handled inside an apparatus with a high degree of hermeticity, air is introduced into the apparatus and the substance is handled in a state in which the volatilized combustible gas is diluted to a concentration at which neither explosion nor fire occurs. With this method for handling a substance from which a combustible gas volatilizes, the combustible gas is diluted with air to a concentration at which neither explosion nor fire occurs, without using inactive gases such as nitrogen or carbon dioxide that have to be produced or purchased. Therefore, a substance from which a combustible gas volatilizes can be inexpensively and safely handled in operations such as mixing and storing.

Abstract: An expansion valve has a solenoid relief valve equipped in an air conditioner for decompressing and expands a refrigerant and supplies the same to an evaporator. A high-pressure refrigerant from a compressor enters a valve chamber. The refrigerant traveling towards the evaporator flows through a first passage. The refrigerant returning from the evaporator toward the compressor flows through a second passage. A valve seat is disposed between the valve chamber and the first passage. A valve body has a refrigerant chamber disposed in parallel to the valve seat and communicates the valve chamber and the first passage. A valve device is capable of coming into contact with and separating from the valve seat. A power element drives the valve device. A solenoid relief valve is disposed between the refrigerant chamber and the first passage.

An expansion valve 1 controls the flow rate of a refrigerant in a valve chamber 14 into which high-pressure refrigerant is introduced by adjusting the gap between a valve means 40 and a valve seat 16, and sends the refrigerant into a passage 20 leading to an evaporator. A solenoid relief valve 100 has a plunger 140 operated by a magnet coil 120, by which a pilot valve seat 152 of a relief valve body 150 is regularly closed. The high-pressure refrigerant introduced to a relief valve chamber 164 of the relief valve body 150 presses the relief valve means 160, regularly closing the valve of the relief valve seat 28. When electricity is supplied to a coil 120, the plunger 140 is attracted toward an attractor 130 and the pilot valve is opened.
