摘要

Safety valve improved for installations water supply, characterized in that it consists of an determining body of a longitudinal duct for interleaved in running the water supply, said body comprising a piston by the action of a spring is susceptible to excel cross in the main duct to establish the shutter thereof, to exist for behind the position of said plunger between the secondary chamber and the main conduit a wide communication port while it is on membrane keeps the plunge withdrawn remaining free el paso, but if the provision of action spring is short it makes the plunge feed and block el paso, so reinstating supply water can only happen in a small amount by the hole sizing and may be evacuated smoothly for any overflow, if output taps are closed, water pa santepor the bore, allows to fill all driver behind the piston, arising the pressure needed to retract the piston back, resulting in the step opening way automatic.
