Example Embodiment

[0029] Example 1

[0030] like Figure 1-5 As shown in a marine terminal proposed foam mixing apparatus of the present invention includes a base 1, above the base 1 from left to right is provided with a fire fighting water inlet means 2, the connection pipe 3, and 4 proportioner outlet conduit 5, One end of the connection pipe 3 communicating with the fire water inlet 2 means the ratio of the mixer 4 and the other end communicates proportioner communicates with the outlet conduit 5 4, 4 is connected to the upper end proportioner inlet tube 6 with a foam, the foam is provided on the inlet tube 6 7 electric ball valve, electric valve 7 is used to enable or disable flow into liquid foam;

[0031] like Figure 3-5 , The proportioner body 4 includes a mixer 411, a sleeve member 413 and control activity 412, the mixer body 411 includes a cylindrical portion 411 a from top to bottom, and the communication portion 411b communicates the mixing portion 411c and is connected to the cylinder de...

Example Embodiment

[0040] Example 2

[0041] A fire extinguishing system, including control module and alarm module, a control module connected to a pressure switch 13, a photoelectric switch 15, an electric butterfly valve 212, and an electric ball valve 7, a start-stop signal of the electric butterfly valve 212, and the electric ball valve 7 are controlled by the control module, a pressure switch 13 can feed back the pressure signal of the firewater inlet pipe to the control module, depending on the set value, the pressure signal can be reflected in the working state, and the pressure signal can be used to determine whether the pipeline is leaked by the valve, which can be used in a non-working state. According to the state of the reaction fire extinguishing device, it should be noted that the pressure switch 13 feeds back the pressure signal of the fire water pipe, and the purifies 412b feedback is the pressure signal when the fire water flows into the mixer body 411 mixing portion 411c;

Abstract

The invention discloses a marine foam fire extinguishing tail end mixing device which comprises a base. A fire fighting water inlet device, a connecting pipe, a proportioning mixer and an outlet pipeline are sequentially arranged above the base from left to right; one end of the connecting pipe is communicated with the fire fighting water inlet device, and the other end of the connecting pipe is communicated with the proportioning mixer; and the proportioning mixer is communicated with the outlet pipeline. The upper end of the proportioning mixer is connected with a foam inlet pipe; and an electric ball valve is arranged on the foam inlet pipe. The marine foam fire extinguishing tail end mixing device can be suitable for small places such as helicopter decks and can extinguish fire in the tail end areas of large places with multiple protection areas, the comprehensive fire extinguishing effect is achieved, the fire extinguishing efficiency is improved, the fire extinguishing speed is increased, and continuous fire spreading is avoided.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing, in particular to a marine foam fire extinguishing terminal mixing device and a fire extinguishing system. Background technique [0002] Foam fire extinguishing system is the most efficient fire extinguishing method for oil fires. The balanced foam proportional mixing device and the pressure foam proportional mixing device are mainly used to protect the flight deck, helideck, JC, boiler room and other areas of the ship. According to the use Different fire extinguishing agents can be used to put out Class A and B fires, and are mainly used to put out oil fires and liquid chemical fires. It can extinguish early fires, inhibit the flow and spread of liquid fuel and the further spread of fires, and has important engineering application prospects. Compared with the pressure-type foam proportioning device, the balanced foam proportioning device has the advantages of convenient maintenance, s...
