JK41X—8Z型快速阀是一种启闭时间短、密封性能好、节流损失小,操作方便省力的新型手动低压阀。由阀体、凸轮、阀杆和密封装置等构成,为单向直通式。阀的开启和关闭,采用凸轮—杠杆机构,能迅速开启和关闭阀瓣。因此,开启阀瓣时,极大地减少了节流损失,在极短的时间,压力头几乎全部转换为速度头,形成了极大地冲击力,增强了冲击效果;关闭阀瓣时,可以迅速截断介质流通,有利于安全控制。
JK41X-8Z type quick valve is a new type manual low pressure valve with short opening and closing time, good sealing performance, small throttling loss, convenient operation and labor saving. It consists of a valve body, a cam, a valve stem and a sealing device, and is a one-way straight-through type. The valve is opened and closed using a cam-lever mechanism that can quickly open and close the flap. Therefore, when the valve flap is opened, the throttling loss is greatly reduced, and in a very short time, the pressure head is almost completely converted into a speed head, which forms a great impact force and enhances the impact effect; when the valve flap is closed, it can be quickly truncated Media circulation is conducive to safety control.
