Description
Technical field
The utility model relates to a kind of for fire protection sector, and profile is pyramid type, is negative-pressure liquid suction structure; Fire water supply is mixed by predetermined ratio with foam solution, forms foam mixing liquid, export pipe network to, put out a fire, belong to fire-fighting fire extinguishing field.
Background technology
Current proportioner does not have negative pressure value measurement function, mostly adopts wafer type, orifice-plate type, and flow resistance loss is bigger than normal, and mixing ratio precision is low, produces, that debugging reaches predetermined mixing ratio is not convenient, the manpower of at substantial, electric power, water source and foam solution.Current proportioner can not meet the application requirement of large-scale dangerous material storage tank zone, refinery device, dangerous material loading stage, offshore oil platform.
Summary of the invention
In order to fill up the blank that current proportioner is measured without negative pressure value; Guarantee the precision of mixing ratio, improve the production of proportioner, test & check efficiency, reduce the loss of proportioner flow resistance.The utility model provides a kind of proportioner, and profile is pyramid type, is negative-pressure liquid suction structure; Nozzle spinning is in body water inlet, and orifice plate is flush-mounted in body liquid sucting port, and below is provided with pad, fastening by locking nut; During work, fire water supply enters body through nozzle, forms negative pressure at body negative pressure cavity, suck foam solution through locking nut, orifice plate, foam solution is mixed by predetermined ratio with water, after all mixed by bulk diffusion pipe, form foam mixing liquid, export pipe network to, put out a fire; Proportioner by: body (1), nozzle (2), O RunddichtringO (3), locking nut (4), orifice plate (5), pad (6) form.
The utility model is achieved in that proportioner is made up of locking nut, orifice plate, O RunddichtringO, pad, nozzle, body.Nozzle spinning is in body water inlet, and orifice plate is flush-mounted in body liquid sucting port, and below is provided with pad, fastening by locking nut; During work, fire water supply enters body through nozzle, forms negative pressure at body negative pressure cavity, suck foam solution through locking nut, orifice plate, foam solution is mixed by predetermined ratio with water, after all mixed by bulk diffusion pipe, form foam mixing liquid, export pipe network to, put out a fire.
The beneficial effects of the utility model are: filled up the blank that proportioner is measured without negative pressure value, feed liquor orifice plate is built-in, volume is little, compact conformation, outlet has 16 ° of diffuser cone pipes, improve the production of proportioner, test & check efficiency, reduce the loss of proportioner flow resistance, improve fire-fighting system functional reliability, meet requirement that is large-scale, long-distance sand transport predetermined ratio foam mixing liquid.
