FIG. 2 is a schematic structural view of the present invention in a pressure-reduced state;
fig. 3 is a schematic structural diagram of the middle housing of the present invention.
The invention will be further elucidated with reference to the drawings and the specific embodiments.
Detailed Description
As shown in fig. 1, an automatic balance pipe network pressure type nozzle comprises a shell 1, a pressure regulating spring 2, a valve core 3 and a lower cover 4, wherein a first boss 11, an ejection hole 12 positioned below the first boss 11, a cavity 14 positioned above the first boss 11 and an air inlet 13 positioned above the cavity 14 are arranged in the shell 1, the valve core 3 is movably sleeved in the shell 1, a second boss 31 is arranged on the outer wall of the valve core 3, a throttling hole 32 is arranged below the second boss 31, the second boss 31 is positioned above the first boss 11, the upper end surface of the pressure regulating spring 2 one end fixedly connected with cavity 14, the upper surface of the other end fixedly connected with second boss 31, and the lower cover 4 is fixedly connected with the bottom of the shell 1.
Furthermore, in the automatic balance pipe network pressure type nozzle, the throttling holes 32 and the injection holes 12 are circumferentially arranged in a plurality of groups in a one-to-one correspondence manner, so that the coverage area of the injection of the nozzle is large.
Further, according to the pressure type nozzle for the automatic balance pipe network, the lower cover 4 is of a convex structure, a circle of groove is formed in the outer side of the upper portion along the circumference, and the first sealing ring 5 is installed in the groove to prevent the fire extinguishing agent from leaking out of the lower portion.
Further, according to the pressure type nozzle for the automatic balance pipe network, the second boss 31 is externally provided with a circle of groove, and the second sealing ring 6 is arranged in the groove to prevent the fire extinguishing agent from leaking from the upper part.
Further, according to the automatic balance pipe network pressure type nozzle, the shell 1 and the valve core 3 are of a tubular structure, the air inlet 13 is conical, the diameter of the top is larger than that of the bottom, the diameter of the bottom is equal to the inner diameter of the valve core 3, and fire extinguishing agents are introduced into the valve core 3 under the drainage effect.
