Problems solved by technology
Due to the phenomenon of water vortex and turbulence in the process of water transportation, it will affect the concentration and spray distance of the sprayed water, which will cause problems such as poor fire extinguishing effect and low water utilization rate.
In order to overcome this problem, a common practice at present is to install a rectifier in the gun head, which is used to divide the cross section of the flow channel to achieve the rectification effect. The effect is limited, and the fire extinguishing effect and water utilization rate of the fire water cannon are still insufficient

Embodiment Construction
[0036] The present case will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0037] This case involves a water outlet rectification device, such as Figure 1-2 As shown, a rectifier body 1 is provided, and the rectifier body 1 has a water cut-off arm 11 and a water flow channel 12 divided by the water cut-off arm 11 . Taking the water passage direction of the water passage 12 as the direction from the front to the rear, the water passage section 11 has a cross-sectional width gradually widening from the front to the rear.
[0038] Preferably, the rectifier body 1 has a cylindrical structure, which is provided with several (such as 4-10) water cut-off arms 11 that are evenly arranged around, corresponding to several (such as 4-10) that are evenly arranged around Water passage 12. In the specific embodiment given, the water-passing cut-off arms 11 are provided with 8 surrounding and uniformly arranged, correspondin...

The invention discloses an effluent rectifying device and a water monitor head. The effluent rectifying device has a rectifier body which has water through cutting arms and water through runners cut by the water through cutting arms. By taking the water through directions of the water through runners as directions front to back, the water through cutting arms are of structures in which the widths of cross sections are gradually increased. According to the invention, the rectifying structure of the effluent rectifying device is mainly designed creatively. The water through cutting arms of the rectifier body are designed of structures in which the widths of cross sections are gradually increased to the water through directions, that is, inclined wave surfaces are formed on two sides of the water through cutting arms, and cut water flows streak from the inclined wave surfaces to be rectified. Under the action of a special rectifying mode, a water eddy phenomenon of effluent water flows is extremely excellently eliminated, the degree of concentration and the jet distance of injection water are greatly improved, and finally, purposes of an excellent fire extinguishment efficiency and high water utilization ratio are achieved.
Description
technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a water outlet rectifying device and a water monitor head. Background technique [0002] Fire water cannon is a kind of fire extinguishing equipment that uses water as a medium to extinguish fires from a long distance. With the strengthening of fire prevention awareness, the construction of fire water cannon facilities is becoming more and more common. A fire nozzle is installed on the nozzle of the fire water monitor, and the water is conveyed and sprayed out through the fire nozzle. Due to the phenomenon of water eddy and turbulent flow in the process of water transportation, it will affect the concentration and spray distance of the sprayed water, which will cause problems such as poor fire extinguishing effect and low water utilization rate. In order to overcome this problem, a common practice at present is to install a rectifier in the gun head, which is use...
