(54) | Valve device for transportable containers for liquid under pressure |
(57) Valve device mounted on keg containers particularly for the distribution of beer
or other drinks, comprising a double valve with a blockable gas passage and a blockable
liquid passage, having a safety system comprising a catch (70) which does not allow
the ejection of said valve when the threading is completely unthreaded unless acting
with the proper equipment beyond the normal working stroke. Said proper equipment
allows the free end of a finger (78) integral with the valve to be engaged between
a vertical wall (74) of the catch and a pair of fins (76) also present on said catch
for the purpose of effecting the retraction of the catch toward the axis of the valve,
making the disassembly of the entire device from the container possible. |
