Description
Technical field
This utility model relates to a kind of fire-fighting equipment, is specifically related to a kind of fire-fighting spray head.
Background technology
According to the regulation of country's " Code for fire protection design of buildings ", the fire-fighting system of industry and civil buildings is the most substantial amounts of employs fire-fighting spraying head.The glass bead of spray head or fusible link, when shower nozzle is heated, owing to the working solution in glass bead is had an effect, make spheroid burst or due to fusible link fusing, come off and open water jet, fire water along water jet spray, play the effect of fire extinguishing.
Spray head is closed at ordinary times, but due to unexpected factor and accident (as close in artificial destruction, accidental impact, closely thermal source, low temperature bursting by freezing, product quality problem etc.), is likely to cause fire-fighting spraying head surprisingly to erupt.This kind of accident once occurs, and conventional processing method is: notice fire protection control room, is shut down by fire-fighting spraying water pump; close the water inlet total valve of this fire-fighting system, open emptying valve simultaneously, the water in this fire-fighting system pipeline is all emptied; after accident spray head stops water spray, change spray head.This process needs dozens of minutes, the fire water that period accident spray head is sprayed at least, not only to the loss caused in building directly or indirectly, simultaneously as whole spraying system of fire fighting is at halted state, is also great potential safety hazard.
Especially large area uses the place of spraying system of fire fighting, such as warehouse, office building, public place of entertainment, airport, station etc., spraying system of fire fighting should prevent unplanned situation out of service as far as possible, so, once there is accident, must leak stopping within the shortest time, maybe will ejection fire water, temporarily drain into sewerage with water pipe.
Utility model content
According to above the deficiencies in the prior art, the utility model proposes a kind of fire-fighting spray head, by simple structural adjustment, in the case of fire-fighting spraying head surprisingly erupts, it is possible to the very first time realizes the control to spray head water outlet, reduce loss.
A kind of fire-fighting spray head described in the utility model, including valve seat, support, glass bead, sealing member and splash box, described pedestal upper end is fixedly linked with valve seat and is provided with the opening connected with valve seat outlet, described valve base surface is provided with screw thread, described pedestal lower end is fixedly linked with splash box, described sealing member closure outlet position in valve seat, described glass bead one end is supported in sealing member, the other end is supported on splash box, and is filled with expanding liquid in described glass bead；It is characterized in that: the bottom of described carrier openings position is provided with mounting seat, described mounting seat and opening connect and surface is provided with screw thread, it is also equipped with connector of the same size with mounting seat bottom described splash box, and the connection of connector thread surface has seal closure.
In this utility model, relative to traditional structure, adding mounting seat, connector and seal closure, regular situation lower seal cover is threadedly connected on connector, does not affect the use of spray head normal function.Once glass bead ruptures and causes spray head surprisingly to erupt, and is taken off by seal closure in time and be installed in mounting seat from connector, it is achieved closure.
Wherein, preferred version is as follows:
Described splash box is horizontal type, upper arc or arc lower.
Described seal closure is cylindrical structural.
Described seal closure surface is provided with anti-slip veins, adds anti-slip veins, even if being stained with water on hand, it is also possible to is easily taken off from connector by seal closure and is installed in mounting seat.
The had the beneficial effect that simple in construction of this utility model, easy to operate, although to add these parts of mounting seat, connector and seal closure, but have no effect on the use that spray head normally works.During fire-fighting spraying hair business external eruption, only need one man operation, can rapidly spray head water spray be blocked within a very short time, it is possible to using water wisely to greatest extent.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described further.
Embodiment 1:
As shown in Figure 1, a kind of fire-fighting spray head, including valve seat 1, support 2, glass bead 3, sealing member 4 and splash box 5, described support 2 upper end is fixedly linked with valve seat 1 and is provided with the opening connected with valve seat 1 outlet, described valve seat 1 surface is provided with screw thread, described support 2 lower end is fixedly linked with splash box 5, described sealing member 4 blocks outlet position in valve seat 1, described glass bead 3 one end is supported in sealing member 4, the other end is supported on splash box 5, and is filled with expanding liquid in described glass bead 3；The described bottom at support 2 aperture position is provided with mounting seat 6, described mounting seat 6 connects with opening and surface is provided with screw thread, it is also equipped with connector 7 of the same size with mounting seat 6 bottom described splash box 5, and the connection of connector 7 thread surface has seal closure 8.
In this utility model, relative to traditional structure, adding mounting seat 6, connector 7 and seal closure 8, regular situation lower seal cover 8 is threadedly connected on connector 7, does not affect the use of spray head normal function.Once glass bead 3 ruptures and causes spray head surprisingly to erupt, and is taken off by seal closure 8 in time and be installed in mounting seat 6 from connector 7, it is achieved closure.
Described splash box 5 is horizontal type.
Described seal closure 8 is cylindrical structural.
Described seal closure 8 surface is provided with anti-slip veins, adds anti-slip veins, even if being stained with water on hand, it is also possible to is easily taken off from connector 7 by seal closure 8 and is installed in mounting seat 6.
