Description
Technical field
The utility model relates to ship's fire fighting field, especially relate to a kind of can pressurize and antifreeze fire hydrant.
Background technology
Boats and ships are installed this trend of fire-fighting system that can meet main cabin requirement, and benefit is general, such as 86mPSV ship, and 50000 ton of half refloating operation ship etc. of diving all needs to install the wet type pressurize fire-fighting system that can meet passenger boat requirement.This wet type pressurize fire-fighting system requires the seawater or the fresh water that are full of certain pressure in pipeline, to ensure spray one effective fire water once opening fire hydrant.
Owing to must have water in pipeline always, outdoor fire hydrant will freeze lower than the water in fire hydrant during freezing temperature in outdoor temperature, and fire hydrant will the bursting by freezing because of internal water freezing and expansion, and therefore outdoor fire bolt needs to discharge water antifreeze; If but water is bled off, do not have water or hydraulic pressure in fire hydrant not, when fire hydrant will be caused to open, at once can not spray one effective fire water.In order to solve this contradiction, generally set up a set of accompanying-heat cable system in addition in prior art, namely fire-fighting in the open and pipe twine accompanying-heat cable (outside wrapping insulating materials) and improve temperature, but so add energy consumption, and result in unnecessary cost.
Utility model content
The purpose of this utility model is, provides a kind of and can discharge water antifreeze and need not set up the antifreeze fire hydrant of accompanying-heat cable system.
A kind of anti-freezing hydrant that the utility model proposes, comprise fire valve, outlet and outlet capping, described fire valve is arranged on the water inlet end of described outlet, and described outlet capping is arranged on the water side of described outlet; Described fire valve is provided with valve rod, and described valve rod is used to open or close the valve of described fire valve; Meanwhile, described anti-freezing hydrant also comprises the first compound plate and compressing member; Described valve rod and outlet are all for being located in wallboard; Described first compound plate and compressing member all can adaptation be sleeved on described valve rod, to carry out press seal by between described valve rod and described wallboard.
Preferably, described compressing member comprises clamp nut, gland and filler; Described gland is sleeved on described valve rod, and described clamp nut to be sleeved on described valve rod and to be pressed on described gland, and described filler is filled out and is located between described valve rod and described gland.
It is nylon or rubber etc. that described filler specifically can be prevented.
Preferably, described outlet comprises vertical pipeline section and horizontal pipeline section, the two perpendicular connection; Described water side is located on described horizontal pipeline section; Described water inlet end is located on described vertical pipeline section.
Preferably, described horizontal pipeline section is for being located in described wallboard, and vertical with described wallboard.
Preferably, described valve rod and described horizontal pipeline section opposing parallel.
Preferably, described anti-freezing hydrant also comprises the second compound plate, and described second compound plate can adaptation be sleeved on described horizontal pipeline section, and for being attached to described wallboard.
Preferably, described outlet capping is provided with internal thread, and the water side of described outlet is provided with external screw thread, and the water side of described outlet capping and described outlet is spirally connected mutually by described internal thread and external screw thread.
Preferably, also comprise flange, described fire valve is connected with the water inlet end of described outlet by described flange.
Beneficial effect: the anti-freezing hydrant that the utility model proposes, during use, the main body of fire valve and the major segments of outlet all can be disposed in the interior; The valve rod of fire valve can pass wallboard, makes its operating side (normally handwheel) be exposed to outdoor, to operate in outdoor; Described wallboard can be passed equally in the water side of described outlet, and is exposed to outdoor with installation outlet capping; Described first compound plate and compressing member all can adaptation be sleeved on described valve rod, carry out press seal by between described valve rod and described wallboard, penetrate into indoor to prevent outdoor aqueous vapor and cold air.Because the indoor temperature on boats and ships is usually above 0 DEG C (generally more than 5 DEG C), and described first compound plate and compressing member have and prevent outdoor aqueous vapor and cold air from penetrating into indoor effect, therefore described outlet still can be full of the fire water of certain pressure when outdoor temperature is lower, and be unlikely to icing bursting by freezing, the requirement that (valve one of fire valve is opened) sprays one effective fire water at once can be reached, do not need again to set up accompanying-heat cable system, thus decrease the cost that energy consumption and this energy consumption bring.
