Background technology
Preaction valve installation is the automatic sprinkler grown up in recent years, and it is automatically to be visited by fire
The preaction valve installation that survey alarm technique and automatic sprinkler system combine, rises double to protection object
Heavily protective effect, is particularly well-suited to cold frost and avoids water stain at ordinary times, does not allow the important of spray by mistake occur
Place, such as places such as computer floor, Generators, reference room, historical data archives, high rack warehouses.
When non-breaking out of fire, it is full of compressed air in this system side pipeline, therefore this system has dry system
Feature, the needs of automatic water jetting under high temperature and severe cold condition can be met.General preaction valve installation is all used
Connect an alarm valve above diaphragm valve to seal gas, there is fluctuation of service, baroque shortcoming.
Summary of the invention
Instant invention overcomes above technical problem, with one, left side drain valve and one, the right definite value pressure control
Valve replaces an alarm valve above the preact of routine, the model that the drain valve on the left side specifies in standard
Playing the effect of the envelope gas that drips in enclosing, i.e. a small amount of water can drip and sealing gland is lived, warning towards waterpower of the right
The pipe leaks gas problem in bell direction limits with a definite value pressure valve, the pressure limit i.e. specified in standard
Default value pressure valve is not opened thus is sealed gas, and this apparatus structure is novel, stable, controls effective,
Controlling barrier film to open when there is fire, allow current enter system pipe network, system is wet by dry transformation
Formula sprinkling fire.
The present invention is realized by following proposal: a kind of preaction valve installation, it include diaphragm valve, drain valve and
