Abstract

The utility model relates to structural improvement of an above-ground hydrant which is anti-theft, anti-collision and leak-proof and belongs to the technical field of fire fighting equipment. The anti-theft, anti-collision and leak-proof hydrant is composed of an anti-theft screw pin upper cover 1, an anti-theft internal pentagonal open side-cover 2, an anti-theft folded sliding plate type connector 3, an internal center locating sleeve 4, a disengaging ejector pin 5, a stacking natural rubber inner sleeve of telescoping wire lining 6, an anti-collision natural rubber flange 7, a separator valve inner core 8 and a spring 10. A special-purpose spanner is used to move the disengaging ejector pin 5 to move downwards for pressing off the separator valve inner core 8, and then the hydrant is opened to supply water. After taking off the special-purpose spanner, the valve core 8 automatically closes water source under the spring 10 and water pressure for stopping water supply. As the disengaging ejector pin 5 and the separator valve inner core 8 are employed to open the hydrant, under the collision of vehicles and the like, one side of the stacking natural rubber inner sleeve of telescoping wire lining 6 is compressed with one side stretching, thereby protecting the separator valve inner core 8 from breakage, and a one-way value functions without leakage, thereby achieving the anti-theft, anti-collision and leak-proof effect.

Description

Antitheft crashproof leakproof above

Technical field

The utility model relates to a kind of architecture advances of above, especially can play the effect of antitheft crashproof leakproof, belongs to the fire fighting device technical field.

Background technology

At present, general above is by top cover, side cover, water band connector, iron chains, last main body, following main body, compositions such as valve rod and valve plug.Because top cover has only two screws to fix, side cover is connected with main body with iron chains, and iron chains disconnects easily, turns on easily with common wrench, and the side cover copper connecting is easily stolen, and valve rod and each parts fixed screw get rusty, and seal has been accelerated degree of aging.Can't normally use during fire extinguishing, also bring harmful effect to city look and feel.Existing fire plug is a valve rod, the structure of valve plug one, in case key is hit, the valve rod valve plug of ining succession is shifted simultaneously, at this moment, high hydraulic pressure is just rapidly excessive from the gap of valve plug displacement, causes the national water resources waste, road ponding, influence road, freeze winter on road, causes the accident.The above periphery that has is added with guardrail, in case breaking out of fire like this makes the fire fighter be difficult to operation, causes the fire fighting time-lag, has strengthened loss.

Summary of the invention

In order to overcome existing easy robber, easily hit the functional deficiency of leakiness.The utility model above adopts in addition pin location of (1) top cover, and pins, and the side cover in addition antitheft slide connector of amounting to links to each other with the fire plug main body; (2) folded type anticollision connector; (3) stem valve separate type check valve apparatus.Can better be antitheft, crashproof and leakproof.

The technical scheme that the utility model above adopted is: (1) top cover and last main flange are in addition pin location of screw principle, pin anti-theft screw pin loam cake 1, and it is stolen to have protected loam cake to be difficult for; The former iron chains of side cover is connected with main body, change into antitheft in pentagonal open side cover, in addition the antitheft board-like connector 3 that slides of amounting to is connected with main body on the fire plug 11.Adopt pentagonal open side lid arrangement, need special spanner to load and unload, common wrench can't be used, and the protection side cover can not turned on easily, even turn on, has the antitheft board-like connector 3 that slides of amounting to link to each other, and can't be stolen.(2) this novel employing separates the device that push rod 5 separates with seperating vale inner core 8, in case fire plug is hit, push rod is shifted simultaneously with main body on the fire plug, and seperating vale inner core 8 still is in closing state under the effect of spring 10 and hydraulic pressure, played the effect of leakproof.(3) middle being folded in the flexible steel wire lining natural rubber of type of main body 11 and following main body 12 flanges overlaps 6 on other this novel employing fire plug, with crashproof natural rubber flange 7, in case fire plug is hit, interior cover 6 of the flexible steel wire lining natural rubber of folded type and natural rubber flange 7 all are that a side pressure is contracted, and opposite side is upheld, if main body 11 is spent greater than 45 with the ground angle on the fire plug, under the effect of crashproof natural rubber flange 7, still can return to the normal position, can normally use, play crashproof effect.

The beneficial effects of the utility model are: can safeguard the overall structure of above, not be damaged, thereby guarantee that fire plug normally uses.

The specific embodiment

In Fig. 1, (1) anti-theft screw pin loam cake 1 is installed in main body top on the fire plug, and antitheft interior pentagonal is opened side cover 2 and linked to each other with the antitheft board-like connector 3 that slides of amounting to, and is connected with main body 11 on the fire plug again; (2) separating push rod 5 overlaps 4 by interior centralized positioning and is connected with main body 11 on the fire plug; (3) main body 12 is an integral body under spring pedestal 9 and the fire plug, and spring 10 is put in the spring pedestal with after seperating vale inner core 8 is connected; (4) cover 6 places crashproof natural rubber flange 7 in the flexible steel wire lining natural rubber of folded type, folded type is flexible, in the steel wire lining natural rubber cover two ends respectively with fire plug on main flange be connected with following main flange, then, with fixed screw last main flange, the natural rubber flange, following main flange links together; The antitheft crashproof leakproof above of forming.

Promote to separate push rod 5 with special spanner.Move down, back down seperating vale inner core 8 and open fire plug water supply.Close fire plug; seperating vale inner core 8 is closed the water source automatically under the effect of spring 10 and hydraulic pressure; stop to supply water; owing to adopt to separate push rod 5 and seperating vale inner core 8 is opened fire plugs, under the collision of automobile etc., cover 6 one side pressures are contracted in the flexible steel wire lining natural rubber of folded type; one side is upheld; protected seperating vale inner core 8 not to be damaged, the effect of performance one way valve can not cause leakage.

Fire plug is important communal facility, is necessity equipment of fire-fighting fire extinguishing.The utility model above is playing positive role aspect the antitheft crashproof leakproof.
