Valve element structure and speed locker thereof
The valve element structure comprises a valve body and a sliding assembly, a sealing cavity is formed in the valve body, and two sets of overflowing holes communicating with the sealing cavity are formed in the surface of the valve body; the sliding assembly comprises a plunger body, the plunger body is connected into the sealing cavity in a sliding mode and divides the sealing cavity into two damping medium containing spaces, the two damping medium containing spaces are communicated through an overflowing channel in the plunger body, and the moving direction of the plunger body is the same as the axial extending direction of the sealing cavity. The length of the plunger body is smaller than the distance between the two sets of overflowing holes and larger than the diameter of the overflowing holes. The plunger body is provided with a first position and a second position, and when the plunger body is located at the first position, the plunger body is located between the two sets of overflowing holes. And when the plunger body is located at the second position, the plunger body seals one group of overflowing holes. Under the action of external force, one set of overflowing holes in the surface of the valve body are completely blocked by the plunger body, pressure cannot leak inwards, and the locking state of the speed locker is stable.
本申请涉及一种阀芯结构及其速度锁定器，其包括：阀体和滑动组件，阀体内部形成有密封腔体，阀体表面开设有两组与密封腔体连通的过流孔；滑动组件包括柱塞体，柱塞体滑动连接于密封腔体内，并将密封腔体分为两个阻尼介质容纳空间，两个阻尼介质容纳空间通过柱塞体上的过流通道连通，柱塞体运动方向与密封腔体轴向延伸方向相同，柱塞体的长度小于两组过流孔之间的距离，柱塞体的长度大于过流孔直径；柱塞体具有第一位置和第二位置，且当处于第一位置时，柱塞体位于两组过流孔之间；当处于第二位置时，柱塞体密封其中一组过流孔。本发明在外力的作用下，阀体表面上的其中一组过流孔被柱塞体完全堵住，压力不会内泄，使速度锁定器锁定状态稳定。
