Description

Technical Field

[0001] The invention relates to the field of flow control valves, and in particular to a multi-channel flow control valve. Background Art

[0002] When using a fire extinguisher to extinguish a fire of flammable or inflammable liquids, aim at the main part of the flame and sweep it. If the liquid fire being extinguished is burning in a flowing manner, aim at the root of the flame and sweep it from near to far, and sweep it left and right until the flame is completely extinguished. If the flammable liquid is burning in a container, the user should aim at the root of the flame and shake it left and right so that the sprayed dry powder flow covers the entire surface of the container opening; when the flame is driven out of the container, the user should continue to spray until the flame is completely extinguished. When extinguishing a fire of flammable liquid in a container, be careful not to aim the nozzle directly at the liquid surface to prevent the impact force of the jet from splashing the flammable liquid and expanding the fire, making it difficult to extinguish the fire. If the flammable liquid burns in a metal container for too long, the wall temperature of the container is higher than the auto-ignition point of the flammable liquid being extinguished. At this time, it is very easy to cause the fire to reignite after extinguishing. If used in conjunction with a foam fire extinguisher, the fire extinguishing effect will be better.

[0003] In order to control the flow rate of the fire extinguisher pipeline, we need to use a valve. However, the current valves are not very good at controlling the flow rate, so we designed a multi-channel flow regulating valve. Summary of the invention

[0006] The lumen of the lower injection pipe is a conical structure that is smaller at the bottom and larger at the top. The speed control head is elliptical in vertical section and circular in horizontal section. The upper injection pipe speed regulating head is twisted to control the distance between the speed control head and the inner cavity of the lower injection pipe speed regulating head, thereby controlling the flow rate.

[0007] A cross 6 is provided in the inner cavity of the upper shooting tube speed regulating head, a connecting rod 7 is vertically provided below the cross, and the bottom of the connecting rod is connected to the speed controlling head.
