DETAILED DESCRIPTION

[0014] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0015] like Figure 1 , Figure 2 and Figure 3 As shown, the tooling for assembling the wedge-shaped valve plate and the sealing ring is used to realize the assembly of the corresponding sealing rings 2 on the two sealing surfaces of the wedge-shaped valve plate 1. Specifically, it includes an assembly support bottom plate 3 for supporting the wedge-shaped valve plate 1 and making the sealing surface at the top thereof in a horizontal state. After the top of the wedge-shaped valve plate 1 is in a horizontal state, it is convenient to cooperate with equipment such as a press, and the two sealing rings 2 are pressed into the two sealing grooves on the wedge-shaped valve plate 1 by the pressure of the press.

[0016] An inclined assembly slope 4 is provided at the top end of the assembly support bottom plate 3, and an assembly lower pad 5 for placing and supporting the wedge-shaped valve plate 1 is fixed on the assembly slope 4. The assembly lower pad 5 is arranged to be abut against the inclined pad on the assembly slope 4. The inclined setting of the assembly lower pad 5 can just fit with the cross-section of the assembly slope 4, so that the sealing surface on the upper side of the wedge-shaped valve plate 1 is in a horizontal state.

[0017] A fixed side positioning plate 6 and a floating side positioning plate 7 are provided on both sides of the assembly lower pad 5, and the fixed side positioning plate 6 is fixed on the assembly inclined surface 4. A valve plate positioning and tightening device is connected between the floating side positioning plate 7 and the assembly inclined surface 4. An assembly side baffle plate 8 is also provided on the side of the assembly lower pad 5, and the assembly side baffle plate 8 is fixedly arranged at the lower end of the assembly inclined surface 4. An assembly upper pad 9 for matching use is provided opposite to the assembly lower pad 5. When in use, the wedge-shaped valve plate 1 is arranged between the assembly side baffle plate 8, the fixed side positioning plate 6, the floating side positioning plate 7, the assembly lower pad 5 and the assembly upper pad 9, and the wedge-shaped valve plate 1 is tightened and fixed by means of the cooperation between the valve plate positioning and tightening device and the floating side positioning plate 7.

[0018] In this embodiment, the upper assembly pad 9 is set as a horizontal pad, so that this embodiment can better contact with the force-applying end of the press, so that the downward force transmission effect is better. The assembly side baffle plate 8 and the assembly lower pad 5 and the assembly upper pad 9 are arranged in an isosceles triangle shape, so that the wedge-shaped valve plate 1 is evenly stressed when it is limited and fixed, preventing unnecessary stress damage to it. The assembly lower pad 5 and the assembly upper pad 9 can be set as circular plates or rectangular plates.

[0019] Among them, the valve plate positioning and tightening device includes at least two floating positioning guide shafts 10 fixedly connected to the floating side positioning plate 7, and the assembly bevel 4 is provided with a guide shaft seat 11 corresponding to each of the floating positioning guide shafts 10 for use with them. The floating positioning guide shaft 10 is movably arranged through the corresponding guide shaft seat 11, and the floating positioning guide shaft 10 between the guide shaft seat 11 and the floating side positioning plate 7 is provided with a valve plate tightening spring 12. In a natural state, the fixed side positioning plate 6 and the floating side positioning plate 7 are relatively close to each other under the action of the valve plate tightening spring 12; when in use, the floating side positioning plate 7 is compressed by the valve plate tightening spring 12 and then moved outwards to facilitate the placement of the wedge-shaped valve plate 1, and the floating side positioning plate 7 is released after the wedge-shaped valve plate 1 is placed, and the floating side positioning plate 7 is pressed against the surface of the wedge-shaped valve plate 1 under the elastic action of the valve plate tightening spring 12, thereby achieving the fixation of the wedge-shaped valve plate 1; after the two sealing rings 2 and the wedge-shaped valve plate 1 are assembled with a press, the floating side positioning plate 7 is compressed by the valve plate tightening spring 12 and then moved outwards, the wedge-shaped valve plate 1 is taken out and the wedge-shaped valve plate 1 to be assembled is placed down and the operation is repeated.

[0020] The description of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
