The specific embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is further described.
As shown in Figures 1 to 6, a kind of fine mist spray head device for vertical plane protection, comprises water distribution portion and is installed on the induction part 1 in water distribution portion; wherein, induction part 1 is temperature-sensitive glass envelope, and temperature-sensitive glass envelope has stainless steel structure protection outward; it is the trigger unit of water mist system; when breaking out of fire, after induction part 1 triggers, temperature-sensitive glass envelope breaks; thin water smoke pump startup; in addition, induction part also can be other common trigger element, as fire detector etc.Water distribution portion comprises the halfpace 2 of hollow setting, for connecting joint 3 and the micro nozzle structure 4 of high pressure liquid source, joint 3 is arranged on the other end corresponding with induction part 1, so that whole fine mist spray head device is received on pipeline, thereby be ejecting device water supply; Halfpace 2 is column structure, and the horizontal cross-section of halfpace part wall is arc, the corresponding micro nozzle structure 4 of wall of arc section has installing hole, micro nozzle structure 4 is arranged on the wall of halfpace, the injection direction of micro nozzle structure 4 is parallel to the horizontal cross-section direction setting of halfpace, and the angle of radiation scope of micro nozzle structure 4 is 170 °-240 °.
Fine mist spray head device is the critical component of fine water mist fire-extinguishing system, and fine mist spray head device has determined protected area and the region of thin water smoke.General, fine mist spray head device can be fixedly mounted on the sparge pipe of fine water mist fire-extinguishing system by modes such as connection such as screw thread, cutting ferrules.In the present embodiment, joint 3 is helicitic texture, the fine mist spray head device of protecting for vertical plane is via the sparge pipe that is fixed on of joint 3 side direction, the wall of micro nozzle structure 4 is installed towards ground setting, because micro nozzle structure 4 injection directions are parallel to the horizontal cross-section direction setting of halfpace, therefore, the thin water smoke of micro nozzle structure 4 ejections is direction straight down, be parallel on the vertical glass curtain wall or other objects vertically arranging that need to protect, to form the thin water smoke layer of one deck between glass curtain wall or other objects vertically arranging and burning things which may cause a fire disaster.Again because 4 integral installations of micro nozzle structure are on an arcwall face; the angle of radiation scope of micro nozzle structure 4 is 170 °-240 °; therefore; when it sprays thin water smoke; the thin water smoke of ejection is just at a fan-shaped face of vertical formation, and due to the effect of gravity, the water droplet of ejection can move downward again; therefore fan-shaped face has just become rectangle, can realize the protection of vertical plane Nei Dui rectangular area.
Due to the interaction between the thin water smoke mist field of each micro nozzle, if every row's micro nozzle all adopts same model, in the middle of mist field, can produce certain gap; If the large micro nozzle of flow is arranged in to outside, can the mist field of low discharge micro nozzle be drawn more sparsely, therefore in every row's micro nozzle, outwards successively decrease successively along the horizontal middle spindle of arc section in the aperture of micro nozzle, the fluid flow that makes micro nozzle ejection also therefrom mind-set outside successively decrease successively.Concrete, when M is odd number, the flow that is positioned at the micro nozzle on horizontal middle spindle is maximum, and then the flow along outside each micro nozzle of circular arc reduces gradually.When M is even number, the micro nozzle flow that is positioned at horizontal middle spindle both sides is maximum, then outwards successively decreases successively, and the concrete selection of the model of nozzle, except outside the Pass the operating pressure with shower nozzle has, depends primarily on the size of needed flow and protection zone.
In order to make thin water smoke mist field more stable, reach the effect of better covering, micro nozzle structure 4 is for being arranged symmetrically with structure, in every row's micro nozzle, the symmetrically arranged a pair of micro nozzle structural parameters of horizontal middle spindle about arc section are identical, and the micro nozzle of same model is all installed in corresponding position.
In addition, in the junction of micro nozzle and halfpace, be also provided with filter screen, to prevent that impurity from stopping up whole ejecting device.
When the height of halfpace is enough high, many row's micro nozzles can be set on the wall of halfpace, consider production cost and the operating efficiency of whole ejecting device, shown in figure, in embodiment, micro nozzle structure 4 all arranges row's micro nozzle.The quantity M of every row's micro nozzle determines according to the angle of radiation of single micro nozzle, makes the integral radiation angle of M micro nozzle at 170 °-240 °.
The above-mentioned description to embodiment is can understand and use the utility model for ease of those skilled in the art.Person skilled in the art obviously can easily make various modifications to these embodiment, and General Principle described herein is applied in other embodiment and needn't passes through performing creative labour.Therefore, the utility model is not limited to above-described embodiment, and those skilled in the art are according to announcement of the present utility model, and not departing from the improvement that the utility model category makes and revise all should be within protection domain of the present utility model.
