Description
Technical field
The present invention relates to fire hose coupling, the snap joint of especially a kind of external fire-fighting many media.
Background technology
Current, along with skyscraper, large area field (factory), storehouse, room widely use, fire extinguishing rescue and social helping day by day complicated, fire-fighting work is faced with many acid tests.As: the compressed air bottle volume that fireman self bears is large, weight large, and the air supply that compressed air bottle stores is limited, seriously limits the pick-up operation ability of fireman, causes many unnecessary life dangers and property loss; And electricity, Voice & Video cannot transmit, and command centre can not understand the actual conditions of fireman and scene of fire in time, cannot carry out effective management and control and the rational management to existing resource to scene.
Summary of the invention
The object of the present invention is to provide the snap joint of a kind of external fire-fighting many media, only grafting action completes the connection of many media, and precisely, the quality time has been won in the rescue for scene of fire, avoids injures and deaths and the property loss of fireman in docking.
Object of the present invention realizes by following technical measures:
The snap joint of external fire-fighting many media, comprise and be arranged on water-band two ends and the water-band female joint of the mutual grafting of energy and water-band male joint, two joint inner chambers are water center cavity, described water-band female joint offers mother-qi road and external port in mother-qi road connects tracheae by mother-qi pipe joint, described water-band male joint offers public air flue and connects tracheae in the external port of public air flue by public gas-tpe fitting, described mother-qi road and public air flue are that independently air flue is not all communicated with water center cavity, after described water-band female joint and water-band male joint are docked, mother-qi road is communicated with public air flue by ventilation cannelure, described ventilation cannelure to be opened in outside water-band male joint and to be communicated with public air flue, in ventilation cannelure both sides, seal groove is opened in the position be positioned at inside water-band female joint, built-in sealing ring prevents gas leakage, under a docking action, complete the corresponding docking of water-band and tracheae simultaneously.
Object of the present invention also realizes by following technical measures:
Be connected with adapter ring by screw thread outside described water-band female joint end, stopping lock is provided with inside adapter ring, described water-band male joint end arranges outer lug boss, after inserting adapter ring, be stuck in stopping lock, described stopping lock comprises lock dog, spring leaf, lock dog guide bracket, the inside groove laying lock dog guide bracket and lock dog is offered inside adapter ring, spring leaf is connected by screw inside lock dog, spring leaf drives lock dog to move radially in lock dog guide bracket, described water-band male joint outside is set with pushing ring, and pushing ring front end withstands on the inclined-plane of lock dog; Adapter ring outer cover has guard ring; Described water-band female joint inwall offers the seal groove for installing sealing ring, and sealing circle is sealed between water-band female joint and water-band male joint, prevents from outwards leaking; Described adapter ring axially offers photoelectricity cable passing hole, and female power supply fibre-optical splice is set in this passing hole end, described water-band male joint outer wall arranges a fixed mount, also photoelectricity cable passing hole is offered in fixed mount, and service message source fibre-optical splice is set in this passing hole end, described female power supply fibre-optical splice docks with service message source fibre-optical splice coaxial-type.
Described public gas-tpe fitting and the position of described fixed mount set by water-band male joint outer wall will be positioned at the rear side of pushing ring and dodge out the distance of axial displacement pushing ring, and on described fixed mount, service message source fibre-optical splice is positioned at the axial displacement that the radial outside pushing ring does not affect pushing ring.
Described fixed mount front end is also provided with and aligns guide pipe, and adapter ring is offered the corresponding gathering sill that aligns, and aligns in gathering sill and arrange sealing ring, described in align guide pipe be positioned at service message source fibre-optical splice outside and with this joint concentric.
Described water-band female joint inwall offers the draining cannelure of the radial direction be interconnected and axial drainage channel, and described drainage channel is communicated with extraneous.
Compared to prior art, the present invention has following beneficial effect:
Compressed air, circuit and optical fiber are installed with in water-band and water-band joint by the present invention simultaneously, and when fire occurs, water, gas and electricity, audio frequency and video just can be connected by an only grafting action simultaneously in the lump, easy to use, save time.
By tracheae by compressed air by be transported to outside scene of fire the inside each fireman, alleviate the volume and weight of the self-contained rescue aid of fireman, compressed air is made constantly to flow to fireman in a steady stream, thus overcome the not enough this situation of the self-contained tolerance of fireman, significantly enhance the mobility of fireman.
Circuit and optical fiber also will by house steward by being communicated to each fireman in the inside outside scene of fire, carry out power supply, Voice & Video transmission, both the need for electricity of the on-the-spot lighting apparatus of fire-fighting can have been met, also can realize scene of fire and fireman's situation overall monitor, make command centre that the situation of scene of fire and fireman in the very first time, can be understood, to realize command centre, effective management and control and the rational management to existing resource are carried out to scene.
The drainage mechanism that anti-sealing infiltrates airway is set inside water-band female joint, after completely avoid Long-Time Service, because sealing is not firm, water that is that bring enters the danger of air flue, drainage mechanism is consisted of draining cannelure and axial straight-through extraneous drainage channel, prevent the sealing ring on the right side of draining cannelure after permanent use, sealing absent-mindedness, because drainage channel is straight-through extraneous, pressure in air flue is greater than the pressure in drainage channel, water can not enter in air flue naturally affects air feed work, has very superior security.
In the photoelectricity joint of male joint, fixed mount is set, increase stability, and fixed mount arranges guide pipe, female joint is then offered the gathering sill of corresponding lead, this guiding mechanism is while guarantee photoelectricity joint perfect alignment, can also ensure that the perfection of opposite side tracheae aligns, so just completely avoid and misplug, what ensure that a grafting action completes all medium joints aligns grafting.
