the damping oil drives the valve body to rotate clockwise in the front process of the clockwise rotation of the rotating shaft, the other side wall of the positioning groove leans against the positioning rib, the first oil passing groove is closed, the damping oil of the first cavity enters the second cavity along the second oil passing groove, the second cavity is gradually increased, the first cavity is gradually decreased, the second oil passing groove is closed in the rear process of the clockwise rotation of the rotating shaft, and the damping oil of the second cavity is extruded to generate a damping effect.
Compared with the background technology, the technical proposal has the following advantages:
when the closestool cover plate is opened, the rotating shaft rotates anticlockwise, the first second oil passing groove is closed, mud blocking oil can pass through the first oil passing groove quickly, the second oil passing groove is opened later along with the rotation of the rotating shaft, the mud blocking oil can pass through the first and second oil passing grooves quickly, and therefore the whole opening process has no damping effect. When the closestool cover plate is closed, the rotating shaft rotates clockwise, the first oil passing groove is closed at the beginning, mud blocking oil can pass through the second oil passing groove quickly, the second oil passing groove is also closed at the later time along with the rotation of the rotating shaft, the mud blocking oil is extruded to generate a damping effect, and the cover plate slowly falls. Because at the beginning that the apron was closed, the second crossed the oil groove and is in the open state, hinders mud oil and can pass through fast from the second oil groove that crosses, does not have damping effect this moment, and the apron can fall fast, and the apron begins slowly to fall until the second oil groove that crosses is also closed, consequently, can shorten the time that the apron fell effectively.
