摘要

PURPOSE: A pipe freezing prevention valve is provided to release pressure within a flow pipe and prevent a pipe from freezing by automatically transferring an opening valve.;CONSTITUTION: A pipe freezing prevention valve comprises a hollow valve body(110), a fluid drain unit, and a pair of support members(130). The fluid drain unit is movably installed inside the valve body and discharges fluid by opening a valve body when pressure inside a flow pipe increases. A pair of support members are combined in the lower part of the valve body and prevent a fluid drain unit from being separated from a valve body. The fluid drain unit comprises a stop member(122), a stem member(123), an elastic member(124), an upper/lower force transmitting member(125,126), and an opening and closing member(121). The stop member restricts the moving distance of the opening and closing member.;COPYRIGHT KIPO 2010
