Abstract
The utility model discloses a manual adjustable type fire water monitor head. The manual adjustable type fire water monitor head comprises a hand wheel protective jacket, a spray nozzle core bar, a nut I, a spray nozzle core, a seal ring, a spray nozzle body, a spray nozzle core frame, a nut II, a spray nozzle sleeve, steel balls, a rubber pad and a thread knotted sleeve. During working, the hand wheel protective jacket is rotated, and the spray nozzle sleeve rotates thereupon, so that the relative location between the spray nozzle body and the spray nozzle sleeve changes. When the relative location between the spray nozzle body and the spray nozzle sleeve is minimal, atomizing spraying can be realized; and conversely, when the relative location between the spray nozzle body and the spray nozzle sleeve is maximal, unidirectional flow spraying can be realized. The mutual conversion between unidirectional flow spraying and atomizing spraying can be realized by rotating the hand wheel protective jacket. The manual adjustable type fire water monitor head is simple, convenient and reliable to operate. Meanwhile, through manual adjustment, the shortcomings that when a hydraulic controlled telescopic cylinder or an electrically controlled transmission mechanism is used for realizing unidirectional flow spraying conversion, a mechanism is complicated and relatively large in size, are eliminated. The manual adjustable type fire water monitor head is particularly suitable for fire fighting occasions needing multiple effects such as fire extinguishment cooling, dilution and protection.
