Detailed Description

The invention will be further described with reference to the following detailed description and accompanying drawings.

Example (b):

as shown in fig. 1 to 4, a simple water-based fire extinguisher valve comprises a valve body 1 and a valve core assembly 5. The valve body 1 is provided with a main flow passage 3 and a discharge passage 4. The main flow channel 3 is arranged vertically. The main flow passage 3 penetrates the upper and lower ends of the valve body 1. The ejection channel 4 is horizontally arranged. One end of the ejection channel 4 is connected with the main flow channel. The inner wall of the ejection channel (4) is provided with internal threads. A valve port 12 is provided in the main flow channel 3. The valve port 12 is in the shape of a conical hole. The diameter of the lower end of the valve port 12 is larger than the diameter of the upper end. The valve core assembly 5 includes a push rod 14. The push rod 14 is slidably connected in the main flow channel 3. The upper end of the push rod 14 extends out of the valve body 1. The lower end of the push rod 14 is provided with a valve core 15 corresponding to the valve port 12. The valve spool is located below the valve port 12. The valve core is embedded with a valve port sealing ring 10. The valve port sealing ring 10 is matched with the valve port 12. The side surface of the push rod 14 is embedded with a sealing ring 11. The sealing ring 11 is in sealing fit with the inner wall of the main flow channel 3. The lower end of the main flow channel 3 is provided with a stand pipe 2. The stand pipe 2 is in a circular pipe shape. The inner ring surface of the stand pipe 2 is provided with a limit convex ring 9. A spring 6 is arranged between the limit convex ring 9 and the valve core 15. One end of the spring 6 is abutted against the limit convex ring 9, and the other end is abutted against the lower end of the valve core 15.

An assist plate 13 is provided in the ejection channel. The booster plate 13 is horizontally disposed. The upper surface of the booster plate 13 is a plane, and the lower surface of the booster plate 13 is a downwardly convex arc surface. The booster plate 13 is connected to the push rod by the connecting rod 8. The connecting rod is L-shaped. One end of the connecting rod is connected with the boosting plate, and the other end of the connecting rod upwards penetrates through the valve body and is connected with the side face of the push rod.

The utility model discloses in, the valve body is connected on the bottle. The upper end of the push rod extends out of the valve body, and the upper end of the push rod is abutted to a pressing handle of the fire extinguisher. The handle is pressed downwards, so that the push rod drives the valve core to move downwards, the valve core is far away from the valve port, and the fire extinguishing agent in the bottle body is sprayed outwards through the main flow channel and the spraying channel. When the fire extinguishing agent is sprayed out, the fire extinguishing agent sprayed out at a high speed can generate downward thrust to the power assisting plate, and the thrust plate transmits the thrust to the push rod through the connecting rod, so that the power assisting effect is achieved on the push rod, the pressing force of a user can be reduced, and the discomfort of the hand of the user is relieved. When the fire extinguishing agent is used up, the fire extinguishing agent stops spraying outwards, and the boosting force disappears. The fire extinguishing agent sprayed at high speed passes through the upper and lower side surfaces of the booster plate. Because the upper side surface of the booster plate is a plane and the lower side surface is a circular arc surface, the flow velocity of the fire extinguishing agent passing through the lower side surface of the booster plate is greater than that of the upper side surface, and according to the Bernoulli effect, the pressure intensity of the side with the high flow velocity is small, and the pressure intensity of the side with the low flow velocity is strong, so that the booster plate can integrally receive downward thrust to form downward boosting for the push rod.
