Description

高压时无扭距球阀
                          技术领域
本发明涉及一种球阀,具体地说是一种高压时无扭距球阀。
                          背景技术
现有用于管道上的球阀,为了使球阀开启省力,通常设有蜗轮装置,而设有这种蜗轮装置的球阀,生产成本较高。此外,这种有蜗轮装置的球阀,阀座与球体之间由于产生磨损,所以对球体的要求很高,而使用寿命相对又较短。
                          发明内容
本发明要的目的是设计出一种高压时无扭距球阀。
本发明要解决的是现有带蜗轮装置的球阀,存在的生产成本高,使用寿命短的问题。
本发明的实施方案是:它包括阀体、连接体、球体、阀杆和阀座,阀座上设有储油室,储油室与控油装置相连。
本发明的优点是生产成本低,球阀开启轻松省力,密封性好,使用寿命长。十分适合在液体输送管道上使用。
                         附图说明
图1为本发明的结构示意图。
图2为本发明局部放大示意图。
                      具本实施内容
下面结合附图及实施例对本发明作进一步说明。
如图所示,本发明包括阀体4、连接体8、球体13、阀杆1和阀座12,阀座12上设有储油室11,储油室11与控油装置相连。控油装置包括顶杆套2、设于顶杆套2内的顶杆3,设于阀体4内的单向阀6、进油道9和出油道7,设于阀座12内的阀座油道10;顶杆套2的前部位于连接体8内,顶杆套2的尾部位于阀体4内,单向阀6顶于顶杆3的顶端;出油道7一端连储油室11,另一端通过单向阀6与进油道9相连,进油道9与阀座油道10相连。阀杆1的边侧开有锥形凹窝,顶杆套2的尾端顶在该锥形凹窝内。储油室11由阀座12、油室盖5和连接体8围合而成。
本发明的工作原理是:阀杆1的下端插于球体13的凹口内,当开始转动阀杆1时,球体13不动,顶杆套2从锥形凹窝内逐步外移,随着顶杆套2的外移,位于顶杆套2内的顶杆3也随之顶于阀杆1而外移,从而推动单向阀6打开,来自管道的高压油通过阀座油道10进入阀体的进油道9,流过单向阀6后,进入阀体出油道7,最后进入储油室11,从而推动阀座12反向移动,使阀座12脱离球体13,与此同进阀杆1也随之带动球体13转动,这样就实现了以零扭距打开球阀目的。
