Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: novel seal structure's gate, apron 4 including pipeline 7 and pipeline 7 front side setting, base 2 has been seted up to pipeline 7 outside up end, connection cassette 3 has been seted up to apron 4 up end, apron 4 has been close to the annular position of pipeline 7 and has been seted up annular dovetail 10, and the joint of annular dovetail 10 inner chamber has sealing washer 6, the edge that sealing washer 6 inboard is close to pipeline 7 one side has seted up oblique fender ring 601, and the laminating of oblique fender ring 601 and pipeline 7 opening part, second turn trough 11 has been seted up to pipeline 7 opening part bottom, and fixedly connected with connecting rod 8 between the second turn trough 11 both sides table wall, and the cover is equipped with the rotation and turns over board 9 in the 8 outside of connecting rod, so that the rotation turns over board 9 and connecting rod 8 rotation mutually, wherein herein fixed connection all can adopt the fixed connection mode of welding or integrated into one piece connection.

Specifically, as shown in fig. 2 and 4, the distance between two sides of the opening on the outer side of the vertical section of the annular dovetail groove 10 is smaller than the distance between two sides of the inner side of the vertical section of the annular dovetail groove, and one side of the sealing ring 6, which is far away from the pipeline 7, is in clearance fit with the annular dovetail groove 10, so that the sealing ring 6 is clamped on the inner wall of the cover plate 4.

Specifically, as shown in fig. 1 and 2, the connection clamping seat 3 is rotatably connected with the base 2 through a rotating shaft, so that the cover plate 4 and the base 2 can rotate with each other.

Specifically, as shown in fig. 1-3, a flange 1 is provided on an outer side wall of one end of the pipe 7 away from the cover plate 4, and a handle 5 is fixedly connected to a bottom of a surface wall of one side of the cover plate 4 away from the pipe 7, so as to facilitate installation of the pipe 7 and manual opening of the cover plate 4.

Specifically, as shown in fig. 2 and 4, a first rotating groove 602 is formed in one side of the sealing ring 6 close to the rotating flap 9, and the first rotating groove 602 is attached to a side surface wall of the rotating flap 9, so that the rotating flap 9 is clamped when the cover plate 4 is closed.

Specifically, as shown in fig. 2-4, an opening of the pipe 7 near one side of the cover plate 4 forms an included angle of 15 degrees with the vertical direction, and the sealing ring 6 is attached to the opening of the inclined plane of the pipe 7, so that the cover plate 4 is automatically closed under the action of gravity.

The working principle is as follows: when the sealing device is used, firstly, the cover plate 4 and the base 2 are mutually rotated through the rotary connection between the base 2 and the connecting clamping seat 3, then the cover plate 4 is naturally overturned towards the bottom by the gravity and mutually extruded with the opening of the pipeline 7 through the 15-degree inclination of the opening of the pipeline 7, and then the inclined baffle ring 601 arranged on the sealing ring 6 is used for enabling the inclined baffle ring 601 to firstly contact with the pipeline 7 in the overturning process of the cover plate 4 until the pipeline 7 is mutually extruded with the sealing ring 6 after the inclined baffle ring 601 is extruded, and at the moment, the inclined baffle ring 601 is completely extruded and attached to the opening of the pipeline 7, so that on one hand, the impact between the sealing ring 6 and the pipeline 7 is buffered, on the other hand, the contact area between the sealing ring 6 and the opening of the pipeline 7 is increased, and further the sealing; secondly, through the connecting rod 8 that pipeline 7 opening part bottom was seted up to and the rotation between connecting rod 8 and the rotation turns over board 9 is connected for it is difficult to block in the opening part bottom of pipeline 7 when the inside great object that flows through of pipeline 7, thereby makes apron 4 more stable cover pipeline 7 opening part.
