Description

A kind of automatic alarm leakproof preact spray system valve group

Technical field

The utility model belongs to fire-fighting equipment technical field, more particularly to a kind of to prevent from spraying with auto-alarm function Preact valve group bad sealing seepage and cause fire-fighting preact spray system occurring freeze damage influence spraying system of fire fighting just The fire-fighting equipment often used.

Background technology

Spraying system of fire fighting is to ensure social enterprises and institutions' production, the visual plant of living safety, due to northern area Very cold, the non-heating building spraying system of fire fighting design limited by heating typically use preact spray system or dry type spraying Leaching system, to solve pipeline " antifreeze " problem.But in engineering practice, because constructing, managing, the link such as material the problem of, usually Pipeline jelly can be caused to undermine threat system effectively to put out a fire.It is known that spraying system of fire fighting is for initial fire disaster of preventing fires, put out a fire to save life and property One of important fire fighting device, be fire extinguishing weapon the strongest, fire extinguishing success rate is higher, occurs after seepage once freeze, Blocking is frozen without water outlet, will result in even more serious consequence.

Seepage without heating region spraying system of fire fighting preact valve group (being functionally similar to remote hydraulically control valve) is one The individual common problem that can not in time find and can reliably prevent, also can be because of the fine sand in water, iron rust even the valve group newly installed Long-term precipitation Deng impurity blocks flap closing, causes the reduction of valve group sensitivity, valve group is not closed completely.Although use reliability Higher stainless steel preact valve group, can reduce internal corrosion problem, but still can not prevent to be mixed into water and in installation process Fine impurities caused by micro seepage.Sluiced weekly in maintenance process, cannot guarantee that the extremely low situation of winter temperature Under, the water leaked out flows slowly into spraying system of fire fighting main pipeline, and be exceedingly fast icing, in time can not thoroughly discharge water at all.Together When frequently open emptying valve, not only need substantial amounts of manpower, also accelerate the damage of emptying valve in advance.On the other hand, it is whole Individual seepage process slowly occurs in pipeline, can not understand and judge in time pipeline from the warning device such as outward appearance and water flow indicator Inside whether ponding freezes.

Preact alarm valve is used for spraying system of fire fighting, it include wet-type valve and drench with rain the valve of valve two and start magnetic valve, It is long-range to be booted up mode interface, emergency start box, supplementing water pressure table plus bottom water valve, experiment draining valve, pressure switch, compression The annexes such as air interface, the unnecessary bottom water valve of row, dew valve, draining valve are formed by stacking, therefore it has both wet-type valve simultaneously and the valve that drenches with rain Function.The valve that drenches with rain leans on water supply network side, and wet-type valve is by fire extinguishing pipe network side.When preact system is in quasi-operating status, The valve side chamber that drenches with rain and cavity of resorption are full of press water, and the fire extinguishing pipe network after wet-type valve is full of compressed air (0.0 3~0.05MPa).Disappear Anti- spray preact alarm valve group plays in theory passes through remote opening electromagnetism when the preact valve group front end, use by water seal Valve or on-site manual open Quick open valve, make leather bag chamber side chamber relief pipeline water supply start.Wet type during daily quasi-operating status Valve side should not have a water appearance, but during due to the fine impurities retained during installation and equipment production and transport in pipe network or with using Between continuity, there is corrosion in preact valve body after general 1 year, and leather bag or bonnet can not seal.Seepage caused by the above situation Water flows slowly into automatic drip water valve connecting cavity on the upside of the valve that drenches with rain, and ensures that wet type valve group side does not have water by dew valve discharge percolating water Flow into.

In actual use due to the difference of valve group manufacturer, automatic drip water valve option is different, there is automatic and people Work waits variety classes manually, while drain discharge is limited, switch sensitivity is unreliable or impurity blocks and internal corrosion or viscous Even, cause percolating water not discharge in time, connect the cavity pressure rise for the ball valve that drips, infiltration is slowly filled with wet alarm valve side Make to be located at the non-gradual water-filling of heating zone pipeline, winter is the generation that pipeline freezes and frozen damage occur.The process is due to seeping water very Slowly and flow is minimum, and the warning device of instruction current will not start alarm in pipe network, and another aspect pipeline is without other water Position monitoring and warning device cause to safeguard that user of service has no way of understanding internal system slight change in time.

Water freezing is exceedingly fast under winter low temperature, even if the use of conventional maintenance inspection method being fire-fighting spraying preact valve group weekly Sluice, can not also guarantee effectively all to discharge leak.The preact valve group automatic water-dropping that another aspect different manufacturers make Valve also has difference in design, and some does not possess good Auto-drainage ability, it is necessary to manually carries out draining, as a result slowly Seepage cause frost crack pipe damage or block can not use, serious threat guard plot safety.The leakage problems of preact valve group Can be because of the material of valve group manufacture, use environment, structure design, many reasons such as usage time, whatsoever reason seepage goes out All it is now the subject matter for having a strong impact on system safety.
