As shown in Figs. 1-3, the fire monitor head annular knurl adjuster of a kind of regulating water flow, including annular knurl blind nut 1, hollow point
Head 2, water diversing head connecting tube 3, sebific duct 4, the first spring 5, second spring 6 and adjusting bolt 7；
The annular knurl blind nut be equipped with inner ring 11 and with inner ring coaxial arrangement outer shroud 12, it is described in be equipped with hollow cavity
Body；The water diversing head outer wall is equipped with card slot, and O-ring seal 8 is equipped in the card slot.The water diversing head is connected to the inner wall of outer shroud
On；The water diversing head connecting tube is inserted into from the bottom of water diversing head, and is connected through a screw thread in the inner ring for being fixed on annular knurl blind nut；Institute
It states sebific duct to be inserted into water diversing head connecting tube from the inner ring hollow cavity of annular knurl blind nut, sebific duct upper end is stuck in the inner ring of annular knurl blind nut
On；First spring is arranged in the cavity between annular knurl blind nut outer shroud and inner ring, and the second spring is arranged on annular knurl spiral shell
In the cavity of lid inner ring；The adjusting bolt is connected through a screw thread the top for being fixed on annular knurl blind nut inner ring.
Further, the water diversing head lower end is equipped with taper surface, and the setting of taper surface is in order to be preferably bonded fire-fighting gun barrel
Water conservancy diversion inclined-plane on body.
Specifically, multiple spout holes 111 are offered on the outer shroud of the annular knurl blind nut.
Further, the bottom of the water diversing head connecting tube is equipped with external screw thread, for being fixed with water knockout drum (not shown)
Connection.
Further, the boss 121 for being clamped sebific duct is convexly equipped on the inner wall of the inner ring of the annular knurl blind nut.
Further, the upper end of the sebific duct is equipped with sebific duct clamp 41, is equipped with to abut the second bullet above sebific duct clamp
The tabletting 42 of spring.
Further, it is equipped with the positive stop lug boss 31 for preventing water diversing head from sliding in the middle part of the Water knockout trap connecting pipe.
The installation process of the fire monitor head annular knurl adjuster is as follows：
(1) O-ring seal is placed into the card slot of water diversing head；
(2) water diversing head connecting tube is inserted into water diversing head；
(3) the first spring is placed between annular knurl blind nut and water diversing head endoporus, is being rolled by water diversing head connecting tube screw threads for fastening
On the internal thread of flower blind nut inner ring, and revolve and put minimum point；
(4) sebific duct is inserted into from annular knurl blind nut inner ring topped hole, and is subsequently placed with second spring；

The operation principle of the fire monitor head annular knurl adjuster is as follows：
When fire monitor is discharged, flow enters water diversing head and annular knurl blind nut inner ring by water diversing head connecting tube, sebific duct
Cavity, so as to shrink second spring, sebific duct moves up, and flow stays the inner cavity between water diversing head and annular knurl blind nut, inner cavity
Hydraulic pressure and water inlet hydraulic pressure because of the setting of multiple spout holes in annular knurl blind nut, an equilibrium state is presented, at this point, point
The water conservancy diversion end face of head is due to hydraulic pressure inside and outside adjuster balance, it is ensured that the concentricity of water diversing head and big gun head makes water flow through excessively
The water hydraulic pressure that the guide face of head is ejected toward all directions all, reduces the friction coefficient with air, reduces water column
Scattering situation, finally make the overall effect of the water column ejected more preferably.
On the other hand, since the first spring is during balancing water pressure, it can shrink and reset, enable water diversing head relative to rolling
Flower blind nut, water diversing head connecting tube and move up and down, so as to which the gap size between water diversing head and fire monitor be controlled change, realization water
The size adjustable range of flow is in 30-50L.
When fire monitor is not reset condition (being discharged), the guide face of water diversing head and fire-fighting monitor body can be because without external water pressure
Both make journey closed state close to each other with the interaction of the first spring, i.e., the water diversing head of annular knurl adjuster can in fire monitor head
The inclined-plane of chamber is close to, and can prevent foreign matter from entering fire monitor intracoelomic cavity at this time and block monitor body, play the role of a seal protection.
The above embodiment is only the preferred embodiment of the utility model, it is impossible to be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to
In the utility model range claimed.
