具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本发明。但是本发明能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下做类似改进， 因此本发明不受下面公开的具体实施例的限制。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本发明。本文所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
实施方式一：
本实施方式一涉及一种螺杆11驱动锥心旋转阀，如图1所示，包括阀体1，阀体1的上端设有上阀盖2，下端设有下压板3，上阀盖2与阀体1通过螺栓连接，阀体1内部设有阀体内孔5，阀体内孔5为锥形孔，在锥形孔内部设有一个锥形的阀芯6，该阀芯6与阀芯6内孔10相配合，在阀芯6下端与下压板3之间设有一个中间板4，中间板4与所述下压板3通过螺栓固定连接在一起，阀芯6的上端设有上出轴7，下端设有下出轴8，所述上出轴7上端与位于上阀盖中心的中心孔9轴连接，所述下出轴8内部为中空结构的内孔10，所述内孔10内设有内螺纹，所述内孔10通过一个螺杆11与位于下压板3外部的驱动机构12连接，所述内孔10与所述螺杆11螺纹连接，所述螺杆11外侧设有凸台13，所述凸台13位于所述中间板4与所述下压板3之间。
在实施方式一中，当驱动机构12正向转动时，驱动机构12带动螺杆11正向转动，螺杆11与阀芯6下出轴8内部的内螺纹配合，此时阀芯6和阀体1内壁压实不转，所以，阀芯6在螺纹的作用下，向上顶起，阀芯6就脱离了阀体1，当阀芯6脱离阀体1，则阀芯6在螺杆11的带动下，正转，当阀芯6转动到需要的位置，驱动机构12反转，带动驱动螺杆11也反转，驱动螺杆11与阀芯6下出轴8内部螺纹拧紧，拉动阀芯6下移，并与锥形阀体1压紧。如果需要另外一个状态，则只需要再重复上面动作即可。
实施方式二：
本实施方式二在实施方式一的基础上，增加了用于精确监测阀芯6位置的传感器14，该传感器14可以加设在上阀盖2下端或阀体1侧壁或阀芯6上端。传感器14可以为位置传感器、磁感应传感器等。
附图2位实施方式二中的一种实施例，该实施例采用的磁感应传感器14，该传感器14包含磁块25及用于感应磁块25的磁传感器14，在本实施例中，上阀盖2上设有一个以上的盲孔，磁传感器14插入盲孔，并与上阀盖2连接，磁块25固定在阀芯6上端，磁传感器14与磁块位置对应，当阀芯6位置转到预定位置后，磁传感器14接收到磁块25的信号，并将信号传送出去，同时驱动机构12根据预设程序进行下一步动作。
实施方式三：
本实施方式三在实施方式一或实施方式二的基础上进行改进，为了能够约束阀芯6的位置，防止阀芯6在运动过程中，尤其是防止阀芯6在反转锁止过程中出现位置偏差，本实施方式在实施方式一或实施二的基础上，增加了一套定位机构15，该定位装置设置在上阀盖2与阀芯6上，定位机构15有多种实施例，图3为其中的一个实施例，该实施例采用定位销17和定位孔16，其中定位销17通过一个压缩弹簧与阀芯6连接，定位孔16位于上阀盖2下端，并与定位销17位置对应，在本实施例中，定位孔16为圆弧形，定位销17顶部为与定位孔16对应的圆弧，只有当阀芯6转到一定位置，定位销17进入定位孔16后，才能使阀芯6在锁止过程中避免阀芯6转动、脱离预设位置，从而在阀芯6定位可靠性上得到进一步的提高。
实施方式四：
本实施方式四是在实施方式一、二或三的基础上进行的改进，为了减少上阀盖2与上出轴7、下出轴8与中间板4和下压板3之间的摩擦损耗，本实施方式增加了防摩擦机构，图4为其中的一个实施例，该实施例是在实施 方式一的基础上进行改进，采用的是在各个摩擦部位增加轴承18，从而减少摩擦。
实施方式五：
本实施方式五是在上述任一实施方式的基础上进行的改进，所述阀芯6与所述中间板4之间设有定位牙盘19，如图5所示，所述定位牙盘19包括定位压盘A和与定位压盘A对应的定位牙盘B21，所述阀芯6下部设有定位牙盘A20，所述中间连接板上设有定位牙盘B21，定位压盘A和定位压盘B成对交叉配合。本实施方式五通过增加定位牙盘19，提高阀芯6位置的定位，从而提高了阀芯6定位的精度。
实施方式六：
本实施方式六在上述任一实施方式的基础上进行的优化，所述阀芯6可以根据实际情况，设置为呈一字型、直角形、工字形或者Y字形，阀体1采用两通阀、三通阀、四通阀、五通阀、六通阀或分配阀。
实施方式七：
本实施方式七在上述任一实施方式的基础上进行的优化，本实施方式七是为了解决在空调、化工或采油等领域，出现泄露的问题，在驱动机构12外围加设有密封盖22，驱动电源通过位于密封盖22底部的端子板连接到外部，形成全密封结构。
实施方式八：
本实施方式八在以上任意实施例的基础上进行的优化，驱动机构12采用了磁力联轴器结构，用以防止出现泄露问题。
实施方式九：
本实施方式九在上述任一实施方式的基础上进行的优化，在阀芯6表面设有过渡层23，过渡层23为镶嵌软金属或者合成材料或者阀芯6表面设有凹坑。
实施方式十：
本实施方式十在上述任一实施方式的基础上进行的优化，在所述上出轴7中间套有弹簧24，所述弹簧24一端压在上阀盖2下表面上，另一段压在阀芯6上表面上，阀芯6上设有贯串上下的压力平衡孔25。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。如在所述阀体1上盖或者阀体1上有用于观测阀芯6位置的视镜，阀芯6上有指示标志，视镜与阀芯6上的标志位置相对应。虽然该实施方式未在上述实施例中说明，但是该实施方式主体仍然属于本发明的保护范围。
应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
