具体实施方式
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1、阀杆3、阀板2和手柄13。阀体1内设有流体储藏室9、流体储藏室9内设有环状滑块8。阀板2与环状滑块8通过连接件连接。阀体1与阀板2之间设有转动限位螺母14，转动限位螺母14与阀板2连接。阀杆3穿过转动限位螺母14和阀板2。阀体1下部设有油道7，油道7内设有单向阀。阀杆3上设有阀杆螺纹15，转动限位螺母14设有内螺纹19。阀杆螺纹15旋于转动限位螺母14内螺纹19上。阀门开启状态下，阀杆螺纹15旋至转动限位螺母14内螺纹19上限，阀杆3下端留有空隙1-2，使单向阀开通。阀门关闭状态下，阀杆螺纹15旋至转动限位螺母14内螺纹19下限，限位螺母14内螺纹19上部留有空隙1-1。
所述的单向阀由阀杆3、钢球6和油道7构成。阀杆3下端顶于钢球6上，钢球6位于油道7内。所述的阀板2二端设有上转头17和下转头18。连接件包括上轴套10、上轴套座11、下轴套5和下轴套座4。上转头17和下转头18上分别安装有上轴套10和下轴套5，上轴套10和下轴套5分别安装于上轴套座11和下轴套座4内。上轴套座11和下轴套座4结构相同，上轴套座11和下轴套座4分别设于阀体1上侧和下侧。
阀体1内设有限位螺母轴套12，转动限位螺母14设于限位螺母轴套12内。所述的阀板2上转头17内设有滑槽16，转动限位螺母14下部设有卡头20，转动限位螺母14通过卡头20卡于滑槽16内。转动限位螺母14在阀板2的滑槽16内可作相对滑动。
本发明的阀门开启方式是：操作人员转动手柄13，连接于该手柄13上的阀杆3随手柄13转动，阀杆3在转动的同时，阀杆3上部的阀杆螺纹15也在转动限位螺母14的内螺纹19中转动，使阀杆3轴向运动并上升。随之打开底部单向阀(即钢球6不再堵住油道7)，使流体储藏室9泄压。流体储藏室9两侧产生压力差，从而使环形滑块8带动阀板2向流体储藏室9一侧移动，使阀板2与阀体1密封失效。这时阀杆螺纹15也旋至转动限位螺母14内螺纹19上限，再转动手柄13，使转动限位螺母14一同转动，就带动阀板2转动，直至阀门完全开启。
