Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a fire-fighting direct injection and fine water spray head comprises a main pipe 1, a rear cover 3 is in threaded connection with one end of the main pipe 1, a water regulating valve core 4 is in threaded connection with one side of the rear cover 3, one side of the water regulating valve core 4 is in fastening connection with a nozzle 6 through a screw 2, a seal ring 5 sleeved on the water regulating valve core 4 is clamped on an inner ring of the nozzle 6, the screw 2 penetrates through the rear cover 3 and is inserted into the side part of the nozzle 6, the water regulating valve core 4 is arranged, the specific injection conversion is controlled by the screwing length of the screw thread of the nozzle 6 by combining the nozzle 6, the twisting nozzle 6 moves forwards to be fine water injection, the twisting nozzle 6 moves backwards to be straight water injection, and then the two modes of injection need to be selected, the convenient conversion of the dual modes of fine water and straight water is achieved, and an operator can conveniently and directly adjust the direct injection mode and fine, through setting up nozzle 6, the spout that the diameter increases from inside to outside in proper order is seted up to one side of nozzle 6, and after rivers passed through the spout department of minor diameter, rivers central pressure was higher than spout pressure all around for rivers are to the local skew that pressure is little, reach the all-round umbelliform thin water injection of unimpeded, improve thin spray effect.

Specifically, one side of the nozzle 6, which is far away from the main pipe 1, is provided with a nozzle, and the diameter of the nozzle is sequentially increased from inside to outside.

In this embodiment, after rivers pass through 6 spouts of nozzle of minor diameter department, rivers central pressure is higher than spout pressure all around for rivers shift to the place that pressure is little, reach the all-round umbelliform thin water injection of unimpeded, improve the thin effect of spouting.

Specifically, the water regulating valve core 4 is formed by fixedly connecting a threaded pipe and a conical block with an isosceles trapezoid section, a nozzle is formed in one side of the conical block of the water regulating valve core 4, the diameter of the nozzle is sequentially increased and decreased from inside to outside, the diameter of the inner ring of the threaded pipe of the water regulating valve core 4 is equal to the diameter of the minimum position of the nozzle of the conical block, a clamping groove matched with the size of the sealing ring 5 is formed in the outer ring of the conical block of the water regulating valve core 4, and the diameter of the minimum position of the nozzle 6 is equal to the diameter of the minimum position of the nozzle of the conical block.

In this embodiment, the outer ring of the conical block is provided with a clamping groove matched with the size of the sealing ring 5, so that the clamping tightness of the sealing ring 5 can be improved.

The utility model discloses a theory of operation and use flow: when the jet type water diversion valve is used and direct-current jet is needed, the nozzle 6 is rotated, so that the distance between the water diversion valve core 4 and the nozzle 6 is far, water flow is buffered at one side, close to the water diversion valve core 4, of the nozzle 6 and is jetted out from the nozzle 6 to conduct direct-current jet, when fine water jet is needed, the nozzle 6 is rotated, so that the distance between the water diversion valve core 4 and the nozzle 6 is close, the closer the distance is, the stronger the impact effect between the water flow jetted out from the water diversion valve core 4 and the nozzle 6 is, after the water flow passes through the small-diameter nozzle, the central pressure of the water flow is higher than the pressure around the nozzle, and the water flow deviates to a place with small pressure.

To sum up, this fire control is directly spouted and thin water shower nozzle, through setting up water transfer case 4, combine nozzle 6, concrete injection conversion is by the precession length control of 6 screw threads of nozzle, 6 forward movements of wrench movement nozzle are thin water injection, 6 backward movements of wrench movement nozzle are straight water injection, and then decide both needs to select the injection mode, reach the convenient conversion of the dual mode of thin water and straight water, be convenient for the direct spout and the thin spray mode of operating personnel direct convenient regulation rivers, through setting up nozzle 6, the spout that the diameter increases in proper order from inside to outside is seted up to one side of nozzle 6, after rivers pass through the spout department of minor diameter, rivers center pressure is higher than spout pressure all around, make rivers to the little local skew of pressure, reach unimpeded all-round umbelliform thin water injection, improve the thin spray effect.
