Description

Automatic control and protective device for fire-fighting pipeline

The utility model relates to the automation control protective device of a kind of fire-fighting equipment, facility.

Fire-fighting equipment, the facility that uses all will be controlled with manually-operated at present, can not in time put out a fire to save life and property after the breaking out of fire, often allows interior among a small circle firing accident stretch into big fire.In the fire fighting process, because high temperature and geographical relationship can not often be incured loss through delay opportunity of combat in directly deeply fiery district.Run into combustible and explosive articles and catch fire, more allow the people feel simply helpless, go back entail dangers to fire fighter's life security.

The purpose of this utility model will overcome above-mentioned prior art weak point exactly, and the automation equipment of a kind of fire extinguishing, outage, warning is provided.

The utility model includes fire-fighting special service valve, pipeline relay, joint door, branch road joint door, shower nozzle, connecting pipe, water facilities and electric control loop.

The fire-fighting special service valve includes housing, spool and conducting strip.Housing comprises outlet housing, suction casing and active tube joint.Active tube joint is enclosed within the outlet plenum and is connected in the port of export with the spiral shell mosquito, and the outlet housing is connected and fixed by conducting strip and suction casing.Spool includes matrix nest, valve, valve body, fast thawing material, basket.The spill nest is fixed in the outlet plenum, and valve body intercepts current with the pouring of fast thawing material after with valve blockage in the spill nest, and basket is relative with the spill nest to be inlaid in the entrance cavity.Conducting strip and spill nest are all one, are that spill nest edge stretches out housing and adopts hot usefulness outward.The fire-fighting special service valve is installed on the series connection pipeline of two curved pipes compositions.Outlet plenum is through series and parallel pipeline, the straight-through shower nozzle of lateral, and entrance cavity is through series connection pipeline, the straight-through fire protection pipeline of bypass line.The fire-fighting special service valve be directly exposed in the middle of the item to be protected by curved pipe or near.When protected scope was caught fire, heat energy can pass to the spill nest by conducting strip, sticked on the fast thawing material fusing of spill nest end face, and valve body loses to support and falls in the basket, opens the valve fire extinguishing.

The pipeline relay comprises transmission device, housing and electric control box.Transmission device includes driven gear, driven shaft, driving gear, driving shaft and control valve.Driven gear is fixed on the driven shaft outer end, by the linked switch in the driven shaft manipulation electric control box.Driving gear is fixed on the driving shaft outer end, and with the meshing transmission of driven gear, initiatively axis body is loaded on compensated cavity inner housing inwall.Control valve handle stem end and driving shaft are connected in compensated cavity, and the handle stem stretches into control chamber by the partition wall passage with control valve.Include control chamber, compensated cavity, inlet and outlet in the housing.Partition wall passage between control chamber and the compensated cavity and handle stem coincide, and control chamber wall and control valve coincide.Control valve can be around half-twist angle, active axle center in control chamber, and the anglec of rotation is opened the exit passageway that enters the mouth during greater than 45 °.Promptly be that water consumption hour can guarantee that also linked switch cuts off fire zone power supply, warning and startup supply equipment before spreading water in protected scope.Electric control box is installed in the housing side, and linked switch is finished instruction before the control valve anglec of rotation is less than 45 °, also covers as housing side opening shelves.The pipeline relay is installed in joint door outlet side between fire protection pipeline and the static pressure pipeline, and the joint door often supplies water, and satisfies the pipeline relay and cooperates the fire-fighting special service valve to carry out monitoring and protecting.

Branch road joint door is installed between fire protection pipeline and the parallel pipeline, often closes.Breaking out of fire in protection domain; when the fire-fighting special service valve lags behind artificial discovery time actuation time or fire have when jeopardizing the combustible and explosive articles that closes on, the available branch road joint door of manually opening is put out a fire or is opened and closes on Fire Net branch road joint door and carry out fire-retardant or cooling.

Connecting pipe includes bypass line, parallel pipeline, series connection pipeline, lateral.Can become various geometric figures according to the different designs of the landform of protected scope, area, stacked items, dwindle disaster area and water during breaking out of fire as far as possible and drench lost area.

Water facilities includes static pressure pipeline, Shui Lou (water tank), water pump, water supply line.Water building (or water tank) level height is higher than shower nozzle.When if protected scope is train, the ship vehicles, will be the source of mainly supplying water by water pump.Because can not establish big volume water tank on this class vehicles top.Can establish a little water tank, utilize the pressure opening conduits relay of little water tank to finish the automatic water-supply fire-fighting program of water pump.
