技术领域technical field

When the ball valve is opened, it mainly uses the rotation of the valve core. Generally, the valve core needs to be rotated 90 degrees or 180 degrees to open the valve and release the fire extinguishing agent stored in the fire extinguishing device. However, the process of the valve core rotating and opening In addition, due to the high pressure in the fire extinguishing device, in order to achieve effective and reliable sealing, usually the valve diameter is small and the flow rate is small, and the sealing ring gaskets on both sides of the valve core and the surface of the valve core are press-fitted. It can be completed, which increases the resistance of the valve core when it is opened, making it difficult for the existing valve to meet the use requirements in terms of opening speed and large spray flow. Therefore, how to increase the opening speed and spray flow of the valve to improve the response of the valve Sexuality has become a pressing issue.
