Embodiment

[0028] a. Standby state

[0029] 1) Close all shut-off valves except the pressure gauge valve 6;

[0030] 2) Open the charging valve 21 to inject compressed air into the compressed air cylinder 15, and observe the pressure change in the compressed air cylinder 15 through the cylinder pressure gauge 4. When the compressed air cylinder 15 reaches the specified pressure, the charging valve 21 should be closed immediately. The pressure of compressed air bottle 15 should be 13~15MPa (130~150kgf / cm 2 ).

[0031] The compressed air pressure in the compressed air bottle 15 must not be higher than 15MPa (150kgf / cm 2 ) to avoid danger.

[0032] 3) Remove the threaded joint 14 with the blind nut on the storage tank 10, inject 128L of fresh water into the storage tank 10 through the threaded joint 14 with the blind nut, remove the cock of the original solution barrel 12, and inject the original solution through the original solution injection port 8. 6L of stock solution is injected i...

Abstract

The invention relates to a mobile fire extinguisher onboard with a medium-fold foam onboard, comprising a storage tank and a compressed air bottle. A filling valve is installed vertically on the upper end of the compressed air bottle, and a pressure reducing valve is installed on one side of the upper end of the storage tank. The air inlet of the valve is connected to the start-up control valve installed on the upper end of the compressed air bottle through the ventilation pipe, and the air outlet of the pressure reducing valve is connected to the raw liquid barrel installed in the middle of the storage tank. The upper end of the storage tank is connected with the lower port of the three-way valve through the liquid outlet pipeline. The two sides of the front end of the lower part of the storage tank are symmetrically arranged with wheels. A support rod, the lower end of the support rod is provided with a support wheel, and the upper end of the storage tank is provided with a handrail. The invention greatly improves the service life and is more convenient to move.

Description

technical field [0001] The invention relates to the technical field of ship-borne fire extinguishers, in particular to a mobile now-mixed medium-fold foam ship-borne fire extinguisher. Background technique [0002] The existing shipboard fire-extinguishing equipment has a small fire-extinguishing radius, needs to be equipped with power such as electricity, has poor independent operability, cannot cope with long-distance or large-area fires, and has poor reliability and safety. Due to the large capacity and heavy weight of shipboard fire extinguishing equipment, it is inconvenient to move. [0003] Patent (Announcement No.: CN 201120573708) discloses a premixed medium-fold foam fire extinguishing device, including a fire hose, a storage tank, a compressed air bottle, an upper bracket and a foam generator, and a foam generator is hung on one side of the upper bracket The compressed air bottle is installed on one side of the storage tank, the fire hose is connected to the cont...
