Operation guide for Fire extinguisher filling equipment
As a preference, the fire extinguisher filling machine is provided with a safety door on the mouth of the dry powder delivery frame, and a bottom plate is provided in the safety box.Put the fire extinguisher on the bottom plate through the dry powder delivery frame, the head of the fire extinguisher enters the dry powder filling gap, the dry powder filling head is aligned with the head of the fire extinguisher, close the safety door, the safety door is safely closed through a latch or lock, the dry powder filling head is aligned with the head of the fire extinguisher, the propulsion device pushes the dry powder filling head towards the head of the fire extinguisher, the interface is tight, after the top is tight, press down the fire extinguisher pressure handle, and then open the dry powder filling valve, and the dry powder filling begins.
Since the safety door is closed, all the fire extinguisher bottles are located in the box. The fire extinguisher does not directly contact the fire extinguisher during the process of filling the dry powder. The safety box is made of materials such as steel plates to separate the body of the operator and all outside personnel from the fire extinguisher at intervals, so as to effectively protect the safety of the operator.
During the specific implementation, the dry powder filling head of the fire extinguisher filling machine is aligned with the head of the fire extinguisher, and the propulsion device pushes the dry powder filling head towards the head of the fire extinguisher. The interface is tightened at the top. After the top is tightened, the valve of the dry powder filling head will automatically open. Press down the handle of the fire extinguisher, and the dry powder will start to be filled.When the dry powder filling is completed, the dry powder filling head leaves the dry powder port of the fire extinguisher head, and the valve of the dry powder filling head is automatically closed.The dry powder filling head of this structure changes the prior art to use a foot valve to control the opening and closing of the dry powder source. The dry powder between the foot valve and the dry powder filling head will be wasted during operation.Therefore, the use of a dry-filled powder head with a valve has the advantage of saving dry powder.When specifically implemented, the dry powder filling head with a valve includes a valve body and a valve core set in the valve body. The valve core is provided with a hollow dry powder guide hole, the head of the valve core is provided with a dry powder filling sealing ring, the middle of the valve core is provided with a groove, the groove is provided with a sealing ring, the tail of the valve core is provided with a step, and it is provided with a dry powder hole, the dry powder hole and the dry powder guide hole communicate, the tail of the valve core is provided with an internal thread, the tail of the valve body is provided with an external thread, the tail of the valve core is rotated with a screw with a valve sealing ring, the valve sealing ring is at the end of the valve body, and the valve body is rotated with a valve with a dry powder inlet Seat, the valve seat is provided with a spring, which is mounted on the head of the screw.
