Problems solved by technology

[0004] In summary, the inside of the diversion gun head in the prior art is a cantilever structure. Although the internal structure of the gun head is symmetrical, the curved pipe structure of the gun body makes the pressure and speed of the water flow into the gun head significantly different. The asymmetric feature causes the tremor and shaking of the inner core rod of the diversion nozzle, which makes the water jet diverge and reduces the range and height of the fire water monitor

Abstract

The invention provides a self-correction adjustable fire monitor head. The self-correction adjustable fire monitor head comprises a water separation head module and a water separator connected in sequence, wherein the water separation head module is used for adjusting the water quantity of a water outlet, and can perform the coaxiality adjustment according to the water pressure to prevent instablewater type caused by deflection; and the water separator is used for counteracting centrifugal force generated during rotary movement of water currents to improve the agglomeration effect of water columns during injection and to reduce the friction coefficient between the water columns and air. Through arrangement of the water separation head module and twelve blades, a water separation head mainpiece moves up and down relative to a cap to adjust the water quantity and the balanced water pressure and to automatically calibrate the coaxiality of the water separation head main piece and a firemonitor so as to guarantee unified water types; and in addition, foreign matters can be prevented from entering an inner cavity of a fire monitor body to block the monitor body.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to a self-correcting and adjustable fire-fighting nozzle. Background technique [0002] The fire water cannon is an important fire-fighting equipment for fighting fires. It is mainly composed of two parts: the cannon body and the nozzle. The gun body is mainly composed of a curved pipe, a horizontal slewing mechanism and a pitching slewing mechanism. According to different structural forms, nozzles can be divided into straight-flow nozzles and diversion nozzles. The direct-flow gun head can only realize long-distance direct-current jet flow. By directly spraying the fire source, the temperature of combustibles can be reduced below the ignition point, thereby realizing fire extinguishing; The short-range spray jet, the spray jet mainly sprays droplets on the fire source at close range, isolating the fire source and oxygen, so as to achieve fire extinguishing. [0003] After ...
