Abstract
The utility model discloses a nozzle of a water mist gun, which is used for fire fighting fire extinction. A jet pipe with a conical spray head is arranged at the front end of the utility model. A current equalizing core composed of a core tube and radial ribbed slabs evenly distributed on the outer wall of the core tube are assembled inside the jet tube. The connection position of the jet tube and the spray head of the current equalizing core, which is at the front end of the current equalizing core, is provided with a swirl plate which is composed of spiral grooves evenly distributed on a circular cylinder body. Compared with the existing similar nozzle, the utility model has the advantages of distant range of water flow and favorable atomizing effect.
Description
The utility model relates to the injection apparatus of fire-fighting fire extinguishing water, is a kind of water mist gun nozzle specifically.
Existing water mist gun nozzle generally is made of jet pipe that is connected with water supply line and the cone nozzle that is arranged on the jet pipe front end, being assemblied in to be used for fire extinguishing on the support and to use.The problem that exists is that current produce stronger eddy current when flowing through jet pipe, causes energy loss, reduces the range of current; In addition, the atomizing of its nozzle current is bad, influence fire extinguishing effect.
The purpose of this utility model is at the problems referred to above, and provides a kind of and help suppressing eddy current, improves the current range and strengthen the water mist gun nozzle of atomizing effect.
The technical scheme that realizes above-mentioned purpose is: a kind of water mist gun nozzle, have jet pipe at the front-end configuration cone nozzle, and in jet pipe, be equipped with the current-sharing core, be provided with spinning disk at its jet pipe of front end of current-sharing core and the joint of shower nozzle; Its current-sharing core is made up of a core barrel and the radially gusset that is distributed on the core barrel outer wall, and its spinning disk is made of a circular cylinder and the helical groove that is 3 ° of-10 ° of inclination angles evenly offered in this cylinder ring outside.
The utility model technical scheme more specifically also comprises: the radially gusset that is distributed on the core barrel outer wall is the 3-8 sheet, and the uniform helical groove that is opened on the circular cylinder correspondingly is the 3-8 bar; The inclination angle that is arranged at the helical groove on the circular cylinder is 5 °.
The utility model is compared with existing similar nozzle, has current far firing range, advantage that atomizing effect is good.
The accompanying drawing drawing is described as follows:
Fig. 1 is this water mist gun nozzle half sectional view;
Fig. 2 is this nozzle current-sharing core front view;
Fig. 3 is this nozzle spinning disk front view;
Fig. 4 is a nozzle spinning disk vertical view.
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Provide as accompanying drawing 1, this water mist gun nozzle has two ends externally threaded jet pipe 2 is set, the front end of this jet pipe conical shower nozzle 1 that is threaded, and the screw thread of jet pipe rear end is used for being connected with feed pipe.In jet pipe 2, be equipped with current-sharing core 3, be equipped with spinning disk 4 at the joint of its jet pipe of the front of current-sharing core and shower nozzle.
Provide as accompanying drawing 2, its current-sharing core 3 is made up of a core barrel 5 and the radially gusset 6 that is distributed on its outer wall.The quantity of its gusset can be selected the 3-8 sheet, and the gusset that accompanying drawing embodiment provides is 6.
Provide as accompanying drawing 3, Fig. 4, its spinning disk 4 is made of a circular cylinder 7 of evenly offering helical groove 8 at lateral surface.The circular cylinder upper end of accompanying drawing embodiment is provided with the convex edge, and purpose is location convenient for assembly.The gusset quantity of the quantity of its groove and current-sharing core correspondingly is set to the 3-8 bar.The inclination angle of every helical groove is 3 °-10 °.Helical groove on the spinning disk that accompanying drawing embodiment provides is 6, and its inclination angle is 5 °.
