Further, valve plate and vulcanized rubber are the rectangle structure, and other trilateral of valve plate except that the top surface all is equipped with vulcanized rubber, and vulcanized rubber's the outside all is equipped with the guide way that matches with the guide rail. The vulcanized rubber is arranged on the other three surfaces of the valve plate except the top surface, so that the valve plate is suitable for places with the liquid level height of substances such as sewage and the like being less than or equal to the height of the valve plate. In addition, through setting up the guide way, make the valve plate reciprocate along the guide rail through the guide way, this kind of crisscross seal structure has further improved the holistic sealing performance of valve plate.

Further, the valve plate and the vulcanized rubber are both of rectangular structures, and the vulcanized rubber is arranged on the edges of the periphery of the valve plate; the outside of vulcanite all is equipped with the guide way with the guide rail matching. The vulcanized rubber is arranged on the edges of the periphery of the valve plate, so that the valve plate is suitable for places with liquid level heights of substances such as sewage and the like larger than the height of the valve plate. In addition, through setting up the guide way, make the valve plate reciprocate along the guide rail through the guide way, this kind of crisscross seal structure has further improved the holistic sealing performance of valve plate.

Further, the cross-sectional shape of the guide groove is U-shaped or trapezoidal. The cross section of the guide groove is designed to be U-shaped or trapezoidal, so that the guide groove is easy to machine and has excellent sealing performance.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

It should be noted that the terms of orientation such as up, down, left, right, top, bottom, etc. in the embodiments of the present invention are only relative concepts or reference to the normal use status of the product, and should not be considered as limiting.

The first embodiment is as follows:

as shown in fig. 1, 2 and 3, the sealing valve plate comprises a rectangular valve plate 1, and the valve plate 1 is made of a steel plate. The edge positions of the left side, the right side and the bottom of the valve plate 1 are all provided with vulcanization holes 11 and coated with vulcanized rubber 2; vulcanized rubber 2 and valve plate 1 and vulcanization hole 11 integrated into one piece, wherein, the quantity of vulcanization hole 11 can be arranged according to actual conditions, and every side is at least arranged more than one, preferably, the position of vulcanization hole 11 is in same one side equidistance evenly distributed, makes vulcanized rubber 2 atress even, connects more firmly. The outside of vulcanite 2 all is equipped with the guide way 21 that matches with guide rail 4, and the top of valve plate 1 is equipped with the connecting piece 3 that is used for push-and-pull valve plate 1 to reciprocate.
