Problems solved by technology

Compared with the pressure-type foam proportioning device, the balanced foam proportioning device has the advantages of convenient maintenance, simple operation, fast response, more flexible structure and more size and weight. The traditional pressure-type and balanced foam-proportioning device can only It is suitable for application in small places such as helidecks, and it is relatively limited. When there are multiple protection areas, especially the protection area at the end, because the flow pressure cannot reach, the fire extinguishing effect cannot be achieved

Embodiment 1

[0030] Such as Figure 1-5 As shown, a marine foam fire extinguishing terminal mixing device proposed by the present invention includes a base 1, and the top of the base 1 is sequentially provided with a fire-fighting water inlet device 2, a connecting pipe 3, a proportional mixer 4 and an outlet pipe 5 from left to right, One end of the connecting pipe 3 communicates with the fire water inlet device 2, the other end communicates with the proportional mixer 4, the proportional mixer 4 communicates with the outlet pipe 5, and the upper end of the proportional mixer 4 is connected with a foam inlet pipe 6, and the foam inlet pipe 6 is set There is an electric ball valve 7, and the electric ball valve 7 is used to start or close the inflow of foam liquid;

[0031] Such as Figure 3-5 As shown, the proportional mixer 4 includes a mixer body 411, a sleeve 413, and a movable control member 412. The mixer body 411 includes a cylindrical part 411a, a communication part 411b and a mix...

Embodiment 2

[0041] A fire extinguishing system, including a control module and an alarm module. The control module is connected with a pressure switch 13, a photoelectric switch 15, an electric butterfly valve 212 and an electric ball valve 7. The start and stop signals of the electric butterfly valve 212 and the electric ball valve 7 are controlled by the control module. The pressure switch 13 The pressure signal of the fire water inlet pipeline can be fed back to the control module. According to the set value, the pressure signal can be reflected in the working state. In the non-working state, the pressure signal can be used to judge whether the pipeline is leaking, that is, the switch state of the valve, and can be timely To reflect the state of the fire extinguishing device, it should be noted that the pressure switch 13 feeds back the pressure signal of the fire water pipe, and the copper tube 412b feeds back the pressure signal when the fire water flows into the mixing part 411c of th...

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...
