High pressure fine mist combination type spray head

Abstract

A combined high-pressure sprayer able to generate the highly atomized water for extinguishing fire features that its fast commutator body has two sealing units at its both ends, one sealing unit is connected to a remote spray tube with a remote nozzle, another sealing unit is connected to a near spray tube with a spherical nozzle for atomizing water, and said fast commutator body is connected to the tube of water gun.

Description

1. Technical field [0001] The invention relates to a high-pressure fine water mist combination nozzle which is a key component in a mobile high-pressure single-fluid fine water mist extinguishing device. 2. Background technology [0002] At present, the spray gun of the high-pressure single-fluid fine water mist fire extinguishing device only has one type of nozzle or two types of nozzles. Installing only one type of nozzle is limited by the type of fire; installing two types of nozzles uses manual rotation to realize the conversion between nozzles, which is inconvenient to operate, and the range is short, and the fog momentum and fog flux are small. Fire extinguishing effect, even delay the timing of fire extinguishing, resulting in unnecessary greater losses of fire. 3. Contents of the invention [0003] In order to overcome the limitations of the existing high-pressure single-fluid water mist fire extinguishing device that the spray gun is limited by the type of fire a...

[0003] In order to overcome the limitations of the existing high-pressure single-fluid water mist fire extinguishing device that the spray gun is limited by the type of fire and the limitations of inconvenient operation and cannot fully exert the fire extinguishing advantages of the rapid combination of high-pressure single-fluid water mist fire extinguishing device, the purpose of the present invention It is to provide a high-pressure water mist combination nozzle, which not only has a fine water mist nozzle, but also has a remote high-pressure water mist nozzle, which solves the problems of short spray gun range, small fog momentum and fog flux, and inability to quickly switch during fire extinguishing The technical solution to the limited problem is that there is a quick diverter head at both ends of the quick diverter body via a one-way valve, a quick diverter head and a remote nozzle installed on the quick diverter body The rods are connected, and the head of the other fast commutator is connected with the short-range nozzle rod installed on the fast commutator body. The remote nozzle rod is equipped with a remote nozzle, and the short-range nozzle rod is equipped with a ball joint. The porous fine water mist nozzle has a water gun rod connection hole on the fast commutator body. The invention has a simple structure, quick nozzle switching, both long and short shooting ranges, low cost, simple and flexible operation, and good effect. The invention has been successfully developed and further improved Improve the fire extinguishing performance of the high-voltage electric single-fluid water mist fire extinguishing device, make the fire extinguishing work easier, seize the favorable opportunity for fire extinguishing, improve the fire extinguishing effect as much as possible, and reduce the loss caused by the fire. Its popularization and application must have huge Economic and Social Benefits
