Description

一种负压水箱调压机构
技术领域
本实用新型涉及一种负压水箱调压机构，尤其是涉及一种用于挤出异型材冷却的负压水箱调压机构。
背景技术
挤出异型材冷却水箱是挤出异型材模具的一部分，是一种负压水箱，在生产过程中水箱中的负压需要根据产品的成型情况随时调整。为了方便调整该水箱需要设置调压机构，现有的调压机构是采用的是一种阀门管件如图1所示，通过阀门手柄1调节阀门2调节水箱负压。其弊端是：第一、不能微调，操作不方便；第二、由于外露部分突出箱体高容易磕碰损坏水箱体；第三、由于是自来水管件很容易丢失。
发明内容
本实用新型的目的是提供一种使用方便的负压水箱调压机构。
本实用新型的应用可以采用如下方案实现：其包括旋转手柄、补芯以及螺杆，补芯设置在螺杆上部，旋转手柄设置在螺杆的上端，螺杆下部设置在负压水箱体上的螺孔内。
所述的补芯下部设置有密封圈。
所述的补芯下部的螺杆上设置有弹簧。
所述的螺杆的下端设置有防脱螺帽。
本实用新型通过左右旋转手柄就可以调整通气量大小，操作方便。有防脱 螺帽和箱体固定，既可防止螺杆脱落，又易拆卸更换。
附图说明
附图1是现有的利用自来水阀门调整负压水箱的调压机构。
附图2是本实用新型的结构示意图。
附图3是本实用新型的图2中调压机构局部放大图。
附图4是本实用新型的调压机构关闭状态图。
图中所示：1、阀门手柄，2、阀门，3、箱体，4、抽气口，5、旋转手柄，6、补芯，7、密封圈，8、弹簧，9、螺杆，10、防脱螺帽，11、进气孔。
具体实施方式
结合附图，说明本实用新型的具体实施例。
如附图2、3、4所示：其包括旋转手柄5、补芯6以及螺杆，补芯设置在螺杆上部，旋转手柄5设置在螺杆9的上端，螺杆9下部设置在负压水箱体3上的螺孔内。在补芯6下部设置有密封圈。在补芯6下部的螺杆9上设置有弹簧8。在螺杆的下端设置有防脱螺帽10。
通过顺时针旋转手柄5这时补芯6会向下移动，补芯6和箱体3之间的缝隙会越来越小，这样从外面进入负压水箱的气体会越来越少，直至补芯6上安装的橡胶密封圈7和箱体3接触，这时完全封死了进入负压水箱的气体通路，通过抽气口4作用使负压水箱处于最高负压状态。反之，逆时针旋转手柄5这时补芯6在弹簧8的作用下离开箱体3，橡胶密封圈7和箱体3间出现缝隙给外界气体从进气孔11进入负压水箱打开通路，最终完成负压水箱调压过程。
