The utility model discloses a simple sewage disposal diverter valve for a collection pool in a production area, which comprises a body component, a valve body, a flow guide pipe and a flow guide pipe, and is characterized in that the body component comprises a valve body and an inlet pipe; the reinforcing part comprises a valve rod body, a valve handle, a valve rod nut, a fixing nut, a rubber sealing plate and a valve bottom plate; the middle of the top end of the valve body is rotationally connected with a valve handle, the valve handle is externally connected with a valve rod, the middle of the upper end of the valve rod is connected with a valve rod nut, the valve handle drives the valve rod and the valve rod nut to rotate, and the middle of the lower end of the valve rod is connected with a fixing nut. The problems that an inlet of a collection pool in an existing production area is usually controlled by an insertion plate to control in and out of waste liquid in the area, the sealing performance is poor, sewage disposal and diversion are not thorough, the liquid level in the collection pool is increased, the overflow phenomenon occurs, and meanwhile the waste water generation amount and the waste water treatment cost are increased are solved.

The utility model discloses a leakproof high-pressure ball valve structure, which relates to the technical field of high-pressure ball valves and comprises a valve body and a plurality of pipelines, the plurality of pipelines are respectively positioned at two ends of the valve body, and a plurality of sealing rings are arranged at two ends of the outer wall of the valve body. The pipeline can be effectively restrained in a sliding mode by being matched with the clamping component, the sliding rail can restrain the moving track of the pipeline, end face sliding in any direction between the pipeline and the connecting face of the valve body is avoided, meanwhile, when the pipeline gets close to the valve body along the sliding rail, the inclined face of the top of the clamping component can be squeezed by the inner wall of the pipeline, and after the pipeline is completely in place, the pipeline is clamped. The compression spring rebounds to push the clamping component to move upwards, so that the top plane of the clamping component is clamped with the inner wall of the pipeline, and after the relative positions of the pipeline and the valve body are preliminarily fixed, the axis deviation of the pipeline cannot be caused by the dead weight or external force disturbance of the pipeline.

The utility model relates to the technical field of immune cells, and discloses a centrifugal separation box for separating peripheral blood immune cells, which comprises a box body shell, a box door is arranged outside the box body shell, a handle is connected outside the box door, sliding rails are connected inside the box body shell, the sliding rails are symmetrically distributed, and the box body shell is provided with an opening. A placement plate is arranged in the box body shell, sliding blocks are connected to the two sides of the outer wall of the placement plate, the sliding blocks are movably connected to the interiors of sliding rails, the exterior of the placement plate is connected with a side plate, the exterior of the side plate is connected with an internal thread ring, and the interior of the internal thread ring is connected with a threaded rod. A sliding rail is arranged on the inner wall of the box body shell, a sliding block is arranged on the outer wall of a placing plate, when an extracting solution is placed, the sliding block can slide in the sliding rail, a worker can pull the placing plate to the outside, the extracting solution placed on the top of the placing plate can be taken, the extracting solution on the innermost side can be taken conveniently, and the working efficiency is improved. And therefore, the taking difficulty is reduced.

The utility model belongs to the technical field of automobile wire harnesses, and discloses a sealing structure between an automobile body hole and a wire harness, which comprises a sealing grommet, a groove is annularly formed in the sealing grommet, the width of the bottom of the groove is larger than that of a notch, the width of the notch of the groove is smaller than the thickness of a metal plate at the position of the automobile body hole, and a via hole for the wire harness to pass through is formed in the middle of the sealing grommet. The diameter of the circle where the groove bottom is located is larger than that of the automobile body hole. The groove is formed in the sealing grommet, sealing between the groove wall at the groove opening of the groove and the metal plate is achieved through matching of the groove opening of the groove and the metal plate at the automobile body hole, sealing between the groove bottom of the groove and the inner wall of the automobile body hole is achieved through matching of the groove bottom of the groove and the automobile body hole, and therefore the double-sealing effect is achieved, the sealing effect is better, and the size is small. And materials are saved.

This utility model belongs to the field of vehicle door sealing technology, and discloses a frameless vehicle door sealing structure and vehicle. The frameless vehicle door sealing structure includes a side panel, a side outer trim panel, a side guide rail, a side sealing strip, and a window glass. The combination of the side outer trim panel and the side guide rail is disposed on the side panel. The side sealing strip includes a first sealing part, a second sealing part, and a connecting part. Both the first and second sealing parts are connected to the connecting part, which can be engaged and fixed with the combination of the side outer trim panel and the side guide rail. During the closing process of the window glass, the upper edge of the window glass is pressed and sealed against the first sealing part, and the second sealing part is pressed and sealed against the inner wall of the window glass.
