Description
Technical field
The present invention relates to the fire prevention field, particularly a kind of a kind of fire-fighting high speed water mist shower nozzle with bigger fire extinguishing scope.
Background technology
At present, known high speed water mist shower nozzle jet angle maximum has only 120 °, and flow is also very little, and the protection domain area is also just very little; The high speed water mist shower nozzle jet angle maximum of other big flow also has only 90 °; the height in space and protection domain area are bigger than very; can not satisfy the height and the smaller space structure performance requirement of protection domain area in space, limitation and restriction the market demand of fire-fighting domain.
Along with highway construction, Freeway Development especially, unidirectional three tracks or Four-Lane Road be the main Construction Party of present highway to.And for the conservation of nature environment, at present highway adopts bridge tunnel combination more, to reduce appropriation of land as much as possible and to the destruction of vegetation.And, usually fire plant to be installed in the tunnel in order to prevent breaking out of fire accident in the tunnel.And the fire plant of installing is made of pipe-line system and high speed water mist shower nozzle usually, and wherein the high speed water mist shower nozzle is arranged at interval along the tunnel direction.For original unidirectional bicycle road or two-way traffic, known high speed water mist sprinkler coverage area enough covers the width in whole tunnel, therefore only need single high speed water mist shower nozzle be set at interval along the tunnel direction and get final product.But for the tunnel of present unidirectional three tracks or Four-Lane Road; known high speed water mist sprinkler coverage area can not cover the width in whole tunnel; therefore need double high speed water mist shower nozzle and dual circuit system be set at interval along the tunnel direction; cause like this to put in order and to strengthen financial cost; numerousization applicator layout is brought a lot of adverse factors to market economy.
Summary of the invention
In order to satisfy the smaller space structure performance requirement of spatial altitude and protection domain area, fully widen fire-fighting market segment space, improve the economy of fire-fighting system device, and a kind of fire-fighting high speed water mist shower nozzle of invention.
Technical problem to be solved by this invention is to overcome the existing the problems referred to above of known technology, discloses a kind of novel a kind of fire-fighting high speed water mist shower nozzle, and good design property widened and extensibility are arranged.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
A kind of fire-fighting high speed water mist shower nozzle comprises:
The body that is connected with fire protection pipeline;
Be installed in the wortex device that makes the water Rotating with Uniform in the described body;
Fairlead, described fairlead has an inner chamber;
Be installed in the pulverizer plate that makes the further uniform atomizing of water that enters in the described inner chamber in the inner chamber of described fairlead;
Be installed in the water that makes on the described fairlead jet in the described inner chamber and form the nozzle that spray in the hole; It is characterized in that, also comprise
Be connected with described body and described wortex device is installed in described intrinsic nozzle cage, the lower end of described fairlead is connected with described wortex device, a described fairlead part in described nozzle cage and and the inwall of described nozzle cage between form an exocoel, it is outer and form an annular spray hole with the running-on place of described nozzle cage that another part is positioned at described nozzle cage; On described fairlead, offer one and link up the hole of described inner chamber and exocoel; A water part that is entered into described exocoel by wortex device enters into inner chamber also through after the pulverizer plate atomizing by the hole on the fairlead, form the hole by nozzle and spray ejection, the water of another part is circularized by the annular spray hole shape and sprays ejection, sprays the water of ejection with the hole and forms combined jet.
Described annular spray hole is outward-dipping oblique annular spray hole.Further, described annular spray hole contraction gradually from inside to outside.
The present invention constitutes the high speed water mist ejection by the combined jet that spray in the hole and annular spray forms, and the protection domain area is formed by the stack of circular area and annulus area, and is more a lot of greatly than the protection domain area of other single high speed water mist shower nozzle.Consider that from economic angle this a kind of fire-fighting can be simplified the extremely loaded down with trivial details property of nozzle layout of sprinkler of fire extinguishing system pipeline with the application of high speed water mist shower nozzle, reduce the cost of system and device.From the market structure space that is suitable for; this a kind of fire-fighting can reduce spatial altitude and protection domain area ratio with the application of high speed water mist shower nozzle; widen other spatial altitude and the smaller space field of protection domain area, thereby also just widened application structure space, market.From the product structure performance of itself, product with compact structure, superior performance.
The beneficial effect of patent of the present invention is: Technological Economy is good, and the market applicability is wide.
