IPC: F16K31/06
Filed: 1985-05-02
Abstract: PURPOSE:To control the opening and closing of a valve apparatus in the state where the intrusion of heat is prevented, by forming a vacuum heat shielding layer between the inner and outer pipes of a double-pipe structure and positioning a valve apparatus body on the inner pipe side and installing a controlling coil outside the outer pipe. CONSTITUTION:In ordinary case, a valve piece 63 is fitted onto a valve seat 62, receiving the retaining strength of a coil spring 67, and the state where the valve apparatus body is closed is held.
