The rotating shaft 4 rotates so that the valve core 3 can rotate in the valve core groove 12, and the gear 6 is located in the control groove 11; a first through hole 14 is respectively provided on both sides of the lower part of the upper valve body 1, and the central axes of the two first through holes 14 are arranged in a colinear manner. The first through hole 14 is connected to the valve core groove 12, and the axial direction of the first through hole 14 is perpendicular to the axial direction of the first rotating shaft 4. A second through hole 15 is respectively provided on both sides of the upper part of the lower valve body 2, and each second through hole 15 corresponds to the position of a first through hole 14. The valve core 3 is provided with a medium channel 13 passing through both ends, and the extension direction of the medium channel 13 is perpendicular to the axial direction of the first rotating shaft 4. The two ends of the medium channel 13 are respectively used to communicate with the two first through holes 14; the piston 9 is slidably installed in the lower part of the lower valve body 2, and the two ends of the elastic component 8 are respectively connected to the lower end of the upper valve body 1 and the upper end of the piston 9, and the lower end of the rack 7 is installed on the piston 9, and the upper end of the rack 7 extends to the control groove 11 and meshes with the gear 6.
具体地，通气孔10为圆形通孔，通气孔10的下端设置于控制槽11上端的中部。Specifically, the vent hole 10 is a circular through hole, and the lower end of the vent hole 10 is arranged at the middle of the upper end of the control groove 11 .
具体地，阀芯3为球形结构，阀芯槽12为球形槽，阀芯槽12的两侧分别设置有圆形安装孔和圆柱形槽，第一转轴4和第二转轴5均为圆柱状结构，第一转轴4穿过圆形安装孔伸至控制槽11中，第二转轴5安装于圆柱形槽中。Specifically, the valve core 3 is a spherical structure, the valve core groove 12 is a spherical groove, and a circular mounting hole and a cylindrical groove are respectively provided on both sides of the valve core groove 12. The first rotating shaft 4 and the second rotating shaft 5 are both cylindrical structures. The first rotating shaft 4 passes through the circular mounting hole and extends into the control groove 11, and the second rotating shaft 5 is installed in the cylindrical groove.
于本具体实施例中，介质通道13为圆柱孔，介质通道13的轴线方向与第一转轴4的轴线方向相垂直。In this specific embodiment, the medium channel 13 is a cylindrical hole, and the axial direction of the medium channel 13 is perpendicular to the axial direction of the first rotating shaft 4 .
于本具体实施例中，第一通孔14和第二通孔15均为圆形通孔，介质通道13的内径、第一通孔14的内径和第二通孔15的内径均相同。In this specific embodiment, the first through hole 14 and the second through hole 15 are both circular through holes, and the inner diameters of the medium channel 13 , the first through hole 14 and the second through hole 15 are all the same.
通过在上阀体1的内部设置球形结构的阀芯3，初始状态时介质通道13的轴线方向与第一通孔14的轴线方向之间的夹角为90度，只需将阀芯3旋转90度即可对液控截止阀进行打开，不但加快了装置的开合速度，还将阀芯3的密封面、上阀体1与介质相隔离，以防其造成腐蚀，使得该装置便于使用。By arranging a spherical valve core 3 inside the upper valve body 1, the angle between the axial direction of the medium channel 13 and the axial direction of the first through hole 14 is 90 degrees in the initial state. The hydraulic control stop valve can be opened by simply rotating the valve core 3 90 degrees, which not only speeds up the opening and closing speed of the device, but also isolates the sealing surface of the valve core 3 and the upper valve body 1 from the medium to prevent corrosion, making the device easy to use.
具体地，活塞9包括基体91和设置于基体91上表面中部的凸块92，基体91滑动安装于下阀体2中的下部，弹性部件8的两端分别卡接于上阀体1的下端和凸块92上，齿条7的下端通过螺栓固定于基体91上表面的一侧。Specifically, the piston 9 includes a base 91 and a protrusion 92 arranged in the middle of the upper surface of the base 91. The base 91 is slidably installed in the lower part of the lower valve body 2. The two ends of the elastic component 8 are respectively clamped on the lower end of the upper valve body 1 and the protrusion 92.

于本具体实施例中，弹性部件8为压缩弹簧。In this specific embodiment, the elastic component 8 is a compression spring.
于本具体实施例中，上阀体1与下阀体2螺纹连接，下阀体2为圆筒状结构，上阀体1的下部外侧设置有外螺纹，下阀体2的上部内侧设置有与外螺纹相匹配的内螺纹。In this specific embodiment, the upper valve body 1 is threadedly connected to the lower valve body 2. The lower valve body 2 is a cylindrical structure. The lower outer side of the upper valve body 1 is provided with an external thread, and the upper inner side of the lower valve body 2 is provided with an internal thread matching the external thread.
于本具体实施例中，齿轮6与第一转轴4通过平键相连接，使得齿轮6与第一转轴4不会发生相对转动，当齿轮6转动时能够带动第一转轴4和阀芯3转动。In this specific embodiment, the gear 6 is connected to the first rotating shaft 4 via a flat key, so that the gear 6 and the first rotating shaft 4 do not rotate relative to each other. When the gear 6 rotates, it can drive the first rotating shaft 4 and the valve core 3 to rotate.
于本具体实施例中，第一转轴4和第二转轴5均焊接于阀芯3上。In this specific embodiment, the first rotating shaft 4 and the second rotating shaft 5 are both welded to the valve core 3 .

本实施例中的液控截止阀主要应用于液压系统中，液控截止阀是直接插装式连接的，因为液压系统中经常有液压阀块或者液压集成块，在液压集成块上面开设了油路通道，如果在液压集成块的一个油路孔口攻螺纹，该螺纹与上阀体1外侧中部的连接螺纹相匹配，进而使得液控截止阀能够螺纹安装于液压集成块上，同时，通过设置O型密封圈16能够防止油液由上述的螺纹连接处泄漏。液压集成块上通常设置有水平且对应设置的介质入口油路通道和介质出口油路通道，以及竖直设置的控制油路通道，控制油路通道为控制口。The hydraulic control stop valve in this embodiment is mainly used in hydraulic systems. The hydraulic control stop valve is directly plug-in connected, because there are often hydraulic valve blocks or hydraulic integrated blocks in hydraulic systems, and an oil passage is opened on the hydraulic integrated block. If a thread is tapped on an oil passage opening of the hydraulic integrated block, the thread matches the connecting thread in the middle of the outer side of the upper valve body 1, so that the hydraulic control stop valve can be threadedly installed on the hydraulic integrated block. At the same time, the O-ring 16 can be provided to prevent oil from leaking from the above-mentioned threaded connection. The hydraulic integrated block is usually provided with horizontal and corresponding medium inlet oil passages and medium outlet oil passages, as well as a vertically arranged control oil passage, and the control oil passage is a control port.
具体使用过程为：通过连接螺纹将本实施例中的液控截止阀安装于液压集成块上，使得上阀体1前侧的第一通孔14与介质入口油路通道相连接，使得将上阀体1后侧的第一通孔14与介质出口油路通道相连接，使得下阀体2的下端与控制油路通道相连接即可。当控制油路通道有压力时，会对下阀体2的下端施加压力时，进而推动活塞9克服压缩弹簧的弹力向上移动，同时带动与之固定连接的齿条7向上移动，再利用齿条7与齿轮6的配合带动第一转轴4进行旋转，以实现阀芯3的前后转动，使上阀体1和下阀体2前后两侧的第一通孔14、第二通孔15与阀芯3内的介质通道13相连通，实现液控截止阀的开启；而当控制油路通道压力过低或没有压力，即下阀体2下方的压力过低或没有压力时，活塞9在压缩弹簧的弹力的作用下向下运动，再利用齿轮6和齿条7的配合使阀芯3回转关闭，对上阀体1和下阀体2前后两侧的第一通孔14和第二通孔15进行阻断，实现液控截止阀的关闭，从而实现了装置的通断操作。The specific usage process is: install the hydraulically controlled stop valve in this embodiment on the hydraulic integrated block through the connecting thread, so that the first through hole 14 on the front side of the upper valve body 1 is connected to the medium inlet oil channel, and the first through hole 14 on the rear side of the upper valve body 1 is connected to the medium outlet oil channel, and the lower end of the lower valve body 2 is connected to the control oil channel. When there is pressure in the control oil passage, pressure is applied to the lower end of the lower valve body 2, thereby pushing the piston 9 to overcome the elastic force of the compression spring and move upward, and at the same time driving the rack 7 fixedly connected thereto to move upward, and then using the cooperation of the rack 7 and the gear 6 to drive the first rotating shaft 4 to rotate, so as to realize the front and rear rotation of the valve core 3, so that the first through hole 14 and the second through hole 15 on the front and rear sides of the upper valve body 1 and the lower valve body 2 are connected with the medium channel 13 in the valve core 3, so as to realize the opening of the hydraulic control stop valve; and when the pressure in the control oil passage is too low or there is no pressure, that is, the pressure below the lower valve body 2 is too low or there is no pressure, the piston 9 moves downward under the action of the elastic force of the compression spring, and then using the cooperation of the gear 6 and the rack 7 to make the valve core 3 rotate and close, and the first through hole 14 and the second through hole 15 on the front and rear sides of the upper valve body 1 and the lower valve body 2 are blocked, so as to realize the closing of the hydraulic control stop valve, thereby realizing the on-off operation of the device.
本实施例中通过在阀芯3的一侧设置第一转轴4、齿轮6和齿条7，利用在活塞9下方加压的方式可以带动齿条7向上运动，进而驱动齿轮6转动，齿轮6通过第一转轴4带动阀芯3进行旋转，使得阀芯3中的介质通道13与两个第一通孔14连通，此时介质可以流通，即通过让阀芯3进行旋转能够实现对液控截止阀通断的控制，省去了电动机等控制设备的安装，结构简单，占用空间小，使用方便，大大节约了生产成本。通过在活塞9和上阀体1之间设置弹性部件8，当活塞9下方的压力消失或较小时，弹性部件8会推动活塞9及齿条7向下移动，以利用齿轮6和第一转轴4的传动将阀芯3进行复位，使得液控截止阀关闭，即能够根据介质压力自动开启和关闭液控截止阀，从而使该装置具有自动开启与关闭的功能。In this embodiment, by arranging the first rotating shaft 4, the gear 6 and the rack 7 on one side of the valve core 3, the rack 7 can be driven to move upward by applying pressure under the piston 9, thereby driving the gear 6 to rotate, and the gear 6 drives the valve core 3 to rotate through the first rotating shaft 4, so that the medium channel 13 in the valve core 3 is connected with the two first through holes 14, and the medium can flow at this time, that is, by rotating the valve core 3, the on-off control of the hydraulic control stop valve can be realized, and the installation of control equipment such as motors is omitted, the structure is simple, the space occupied is small, the use is convenient, and the production cost is greatly saved. By arranging the elastic component 8 between the piston 9 and the upper valve body 1, when the pressure under the piston 9 disappears or is small, the elastic component 8 will push the piston 9 and the rack 7 to move downward, so that the valve core 3 is reset by the transmission of the gear 6 and the first rotating shaft 4, so that the hydraulic control stop valve is closed, that is, the hydraulic control stop valve can be automatically opened and closed according to the medium pressure, so that the device has the function of automatic opening and closing.
