Embodiment Construction

[0018] The spray core is embedded in the spray nozzle, the spray nozzle is screwed into the screw hole of the nozzle body, the mandrel is inserted into the nozzle body, and locked with a screw cover, and a filter screen is set at the water inlet of the mandrel. When spraying, high-pressure water flows through the filter screen and mandrel into each spray nozzle of the nozzle body for atomization and spraying; the tangential reaction force generated by each spray nozzle makes the nozzle body rotate to achieve 360° full coverage and uniform spraying. Effectively eliminate thermal radiation, infrared radiation and radar features of protected facilities; function of blocking hot air flow and harmful smoke.

[0019] 1) Material: 316L stainless steel is used for the atomizing core, screw cover, filter screen and ball; the locking bolt is made of copper alloy, and the surface is chrome-plated for anti-corrosion treatment; the mandrel, nozzle body and spray nozzle are made of titanium ...

Abstract

The invention relates to a rotary water mist sprayer which is usually installed outside protected facilities, at safety evacuation exits, air wells and the like. The rotary water mist sprayer adopts a structure of dual-way rolling balls and dual-way O-shaped rings and is shaped as a mushroom. When the rotary water mist sprayer works, a high-pressure water source enters a mandrel through a filter screen and arrives at each spray core and spray nozzle of the sprayer body, the water flow is atomized into fine water drops less than 120 mu m to be sprayed, and the eccentric reacting force generated by each spray nozzle enables the sprayer body to rotate around the mandrel, and the water mist is sprayed in complete 360 DEG C. The invention belongs to the fields of fire control isolation, protection cooling and elimination of infrared radiation and radar signature of protected facilities. The rotary water mist sprayer is provided with a lock plunger, a filter screen, the mandrel, the rolling balls, screws, the spray cores, the spray nozzles, the spray body and the O-shaped rings and is widely applied to military industry, electric power, chemical industry, aerospace, ships, metallurgy, undergrounds and tunnels.

Description

technical field [0001] The invention relates to a new type used in the fire protection industry, which adopts double-channel ball and double-channel O-shaped sealing ring structure, and has a mushroom-shaped shape; when working, the high-pressure water source enters the mandrel through the filter screen, and reaches the spray cores and spray nozzles of the nozzle body. , the high-pressure water flow is atomized and decomposed into fine water droplets less than 120um for spraying. The eccentric reaction force generated by each spray nozzle makes the nozzle body rotate around the core axis, so that the fine water mist can spray 360°, covering complete and uniform. It belongs to the application field of fire control and isolation, protective cooling, elimination of infrared radiation of protected facilities, and elimination of radar features. Background technique [0002] The current national standard GB5135.3-2003 water mist nozzle has a low rated working pressure of 0.35MPa; ...
