Description
Technical field
The utility model relates to a kind of shower nozzle, relates in particular to the fine mist spray head that a kind of fire-fighting fire extinguishing is used.
Background technology
Fine water mist fire-extinguishing system is a kind of novel fire-fighting system, and it has the two-fold advantage of extinction using gas and water fire extinguishing, is one of halon fire agent (brokenization ozone layer) substitute technology of tool potentiality.As the fine mist spray head of atomizing executive component, be the most crucial parts of whole fine water mist fire-extinguishing system.At present, fine mist spray head mainly adopts centrifugal atomizing, and its atomization mechanism is the rotating liquid that utilizes nozzle body inner nozzle core to produce, and accelerates the hollow diffusion taper liquid film of ejection through nozzle body outlet, utilizes the speed difference of liquid and outside air and fragmentation, atomizes.Corresponding nozzle core often adopts the cyclone structure forms such as eddy flow groove, tangential slot, tangential hole, inclined hole sheet, swash plate, but grooved, inclined hole, swash plate import be complex structure often, and machining accuracy is restive, therefore the flow uniformity of shower nozzle is poor, mist shape is irregular, thereby impact atomizes, the fire extinguishing effect.And existing fine mist spray head generally adopts external screw thread to connect, and needs extra special joint, has increased the cost that engineering is used.The part shower nozzle adopts internal thread to connect, but filter element is not installed, and the danger of obstruction is arranged in the use procedure.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of fine mist spray head to be provided, and this shower nozzle adopts internal thread to connect, and filter element is installed, and nozzle core is simple in structure, be easy to processing, pulverability is stable.
The utility model is achieved through the following technical solutions:
A kind of fine mist spray head, include nozzle housing, be pressed with the filter screen seat of filter screen, in the nozzle body of nozzle core is housed, it is characterized in that: the import of described nozzle housing is stepped hole, and two sections stepped holes are respectively equipped with internal thread, be combined with the filter screen seat that is pressed with filter screen in the inner bolt hole stepped hole of lower end, the bottom surface of described filter screen seat is provided with flowing hole, on the outer conical surface of the bottom of described nozzle housing nozzle body is installed, be equipped with nozzle core in the described nozzle body, described nozzle core is comprised of two parts up and down, top is axially to cut out the solid that two symmetrical planes form on a cylinder, the bottom is a cylinder, described nozzle core inside is provided with blind hole, described blind hole openend communicates with the nozzle body inner chamber, and blind hole top communicates described nozzle core and nozzle body interference fit by two tangential holes on the nozzle core symmetrical plane with the nozzle housing inner chamber, lower cylinder is pressed into the nozzle body inner chamber, and described nozzle body and nozzle housing seal by gasket seal.
The bottom surface of described filter screen seat is evenly equipped with several flowing holes, and filter screen and filter screen seat interference fit.
4～6 nozzle bodies that are equipped with nozzle core evenly are installed on the outer conical surface of described nozzle housing bottom.
The pore size of two tangential holes of described nozzle core, axis spacing and nozzle body outlet aperture size match with flowrate coefficient of sprinkler.
The utility model has the advantages that:
(1) nozzle core of the utility model employing is simple in structure, is easy to processing, the water smoke mist shape rule of ejection, stability of flow.
(2) the utility model can go out different discharge coefficients by the size of two tangential holes of change nozzle core and the size design of spacing and nozzle body outlet aperture.
(3) the utility model and pipeline are easy to connect, and filter element is housed, and effectively prevent from stopping up.

The specific embodiment
Referring to accompanying drawing, a kind of fine mist spray head is made of nozzle housing 1, filter screen seat 2, filter screen 3, nozzle core 4, gasket seal 5, nozzle body 6.The import department of nozzle housing 1 is provided with the twice internal thread, and lower internal thread is used for being screwed into the filter screen seat 2 that is pressed with filter screen 3, and the bottom surface of filter screen seat 2 is provided with 7 flowing holes 7, and filter screen 3 interference fit are pressed on the bottom surface of filter screen seat 2; Upper internal threaded is used for being screwed into pipeline.4～6 screwed holes that are evenly arranged are arranged on the outer conical surface of nozzle housing 1 bottom, be used for installing nozzle body 6, nozzle body 6 seals by gasket seal with nozzle housing 1.Be equipped with nozzle core 4 on the nozzle body 6, nozzle core 4 is comprised of two parts up and down, and top is axially to cut out the solid 41 that two symmetrical planes 43 form on a cylinder, and the bottom is a cylinder 42; Nozzle core 4 and nozzle body 6 interference fit, lower cylindrical body 42 is pressed into nozzle body inner chamber 62; Nozzle core 4 inside are provided with blind hole 45, and blind hole 45 openends communicate with nozzle body inner chamber 62, and blind hole 45 tops communicate with the nozzle housing inner chamber by two tangential holes 44 on nozzle core 4 symmetrical planes 43; The large I in the pore size of two tangential holes 44, axially bored line spacing and nozzle body outlet opening 61 apertures designs according to the difference of flowrate coefficient of sprinkler.
