Abstract
A passive self-extinguishing water-curtain valve for a tunnel belongs to security inspection and automatic control equipment field, which is characterized in that the valve body of a water-curtain valve is provided with a lagged bonnet, a valve handle component is arranged inside the valve body, a magnetic pillar assembling unit is embedded inside the upper end of the valve handle, and the lower end of the valve handle is connected with a piston which can up-and-down move with the valve handle. When a water outlet in the valve is opened or closed, the valve handle is driven by a solenoid operated valve outside the lagged bonnet. In case of fire, fire fighting water is sprayed out through a nozzle along a spraying pipe and forms fan shape water-curtain, and more nozzles can be installed according to size of the tunnel. When fire is extinguished in certain section of the tunnel, the valve can self-close to break current.
Description
Technical field
A kind of tunnel belongs to safety check and automatic control equipment field with passive self-extinguishing water curtain valve.Be mainly used in tunnel, the tunnel automatic fire protection system of railway, highway.
Technical background
Along with modernization process, the track of tunnel type more and more becomes each metropolitan main vehicles, and the development trend of this tunnel traffic form, has extended to highway, seabed.The defective of this tunnel traffic is, a large amount of of personnel and goods are flowed, and its tunnel operation system is very easily suffered damage, and any small accident all can cause serious consequence in the tunnel, and wherein the accident that causes of fire is the most serious! The existing tunnel fireproofing technique is that video monitoring equipment and traditional fire-fighting equipment are installed in the tunnel, as disposable sprinkler.This disposable device can not automatically shut down the water source, not only causes a large amount of wastes of water resource; The more important thing is, when fire takes place, when particularly the condition of a fire spreads to whole tunnel, when many disposable sprinkler work, though the fire around it is knocked out, but still spray more than! And the tunnel is generally all longer, and portion's section of possible other firm working fire owing to those sprinklers of having worked are wasted water in a large number, and causes sprinkler water resource herein just not have inadequately or at all, thereby causes extremely serious consequence.The tunnel fire hazard that repeatedly takes place just has the bitter lesson of this respect in the world.
Summary of the invention
Purpose of the present invention provides a kind of tunnel with passive self-extinguishing water curtain valve.
Technical scheme of the present invention is achieved like this: system is made up of automatic water curtain valve, spray line, water spray nozzle; It is characterized in that having on the valve body of water curtain valve band cover valve gap, valve inner has valve rod assembly, and valve rod studs with magnetic column combination spare in the upper end, and sealing is installed in the nonmagnetic metal sleeve, the valve rod lower end is connected with piston, and piston moves up and down with valve rod, open or closing valve in delivery port; The outside of valve gap cover is with the magnetic control cover that can slide up and down, and the magnetic control cover is embedded in the interior bottom of interlock cover, and the outside of interlock cover is with spring shape heat-sensitive element; The outer top of concave groove is withstood in the bottom of spring shape heat-sensitive element, and the middle part baffle plate of interlock cover is withstood on top, and interlock cover bottom is installed in the inner bottom part of concave groove; The inner top of temperature control cover is withstood on the top of return spring, and the bottom is installed in above the middle part baffle plate of interlock cover; The installation that repels each other of each magnetic pole in magnetic ring component and the magnetic column assembly; The outside of temperature control cover has the TEMP hole, and the bottom is connected with band cover valve gap by screw thread; Valve export is connected with spray line by screw thread, and spray line can be connected with several water spray nozzles simultaneously, and valve also can directly be connected with water spray nozzle, and the water spray nozzle delivery port is one flat fan-shaped, and delivery port can be opened the front at nozzle, also can drive in the side.
When environment temperature is in normal range (NR), spring shape heat-sensitive element is contraction-like, and return spring is pressed on the interlock cover in the concave groove, and magnetic column combination spare, valve rod, piston that the magnetic control cover in the interlock cover drives in the cover valve gap move down, piston is sealed the delivery port in the valve body, blocks current! There is not the fire water ejection in spray line, the water spray nozzle; Temperature control cover on the water curtain valve detects the condition of a fire takes place in the tunnel, when environment temperature raises unusually, spring shape heat-sensitive element moves expansion rapidly, promoting the interlock cover moves upward, magnetic control is enclosed within when moving up, the magnetic column combination spare, valve rod, the piston that drive in the band cover valve gap move upward, hydraulic pressure backs down piston rapidly, fire water sprays through nozzle along spray line, because jet expansion is one flat fan-shaped, the water of ejection forms fan-shaped water curtain, and nozzle can be installed several or more according to the size in tunnel on spray line; After certain on-the-spot condition of a fire was extinguished, valve was closed automatically, blocks current, thereby had avoided the influence to other shower nozzle discharge.
The invention has the beneficial effects as follows: valve is easy for installation; The opening and closing of fault of valve does not promptly need electric power or other mechanical force without any need for outer power; After on-the-spot recovery is normal, the energy automatic-closing valve; When in the such environment in tunnel, using, can form the water curtain fire extinguishing system of disjunction formula.
