Detailed Implementation

[0029] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0030] Example 1:

[0031] Provided such as Figure 1-8 The illustrated wedge-shaped vacuum rectangular transfer valve includes: a valve body 1, with a through groove 11 on the side wall of the valve body 1; a power unit 2 on the top of the valve body 1; a first wedge block 3 and a second wedge block 4 inside the valve body 1; the first wedge block 3 and the second wedge block 4 are connected by a first spring 8; a sealing ring 5 is provided on the surface of the second wedge block 4; and the power unit 2 is fixedly connected to the first wedge block 3 by a connecting rod 6. The sealing ring 5 is used to seal the perimeter of the through groove 11. The power unit 2 can be an electric motor, a pneumatic cylinder, or a hydraulic cylinder.

[0032] The first wedge block 3 has fixing plates 31 on both sides, and bearing seats 7 are provided on the fixing plates 31. Bearings 71 are installed inside the bearing seats 7. A fixing rod 72 is provided inside the bearing seats 7, and the fixing plates 31 and bearing seats 7 are connected by a second spring 73. The bearings 71 roll on the side wall of the valve body 1, keeping the first wedge block 3 stable during movement. The second spring 73 provides elastic force to the first wedge block 3, pressing the fixing plates 31 tightly inside the bearing seats 7, preventing the first wedge block 3 from moving and reducing the vibration of the first wedge block 3 during movement.

[0033] The inclined surfaces of the first wedge block 3 and the second wedge block 4 are opposite each other. Through the wedge structure of the first wedge block 3 and the second wedge block 4, the pressure of the first wedge block 3 on the second wedge block 4 gradually decreases when it rises and gradually increases when it falls, making the movement of the second wedge block 4 more stable and squeezing the sealing ring 5 on the second wedge block 4 to seal the valve.

[0034] The first wedge block 3 has a through-hole limiting groove 32 on its side wall, and the second wedge block 4 has a limiting block 41 on its inclined surface. The limiting block 41 is slidably connected to the limiting groove 32. The limiting block 41 slides within the limiting groove 32, which limits the limiting block 41 and further limits the second wedge block 4.

[0035] The first wedge block 3 has a through first connecting groove 33 on its side wall, and the second wedge block 4 has a through second connecting groove 42 on its side wall. A first connecting post 34 is provided in the first connecting groove 33, and a second connecting post 35 is provided in the second connecting groove 42. The first connecting post 34 and the second connecting post 35 are connected by a first spring 8. The elastic force of the first spring 8 keeps the inclined surface of the second wedge block 4 in close contact with the inclined surface of the first wedge block 3.

[0036] The bottom of the first wedge block 3 is provided with a first positioning block 35, and the bottom of the second wedge block 4 is provided with a second positioning block 44. The first positioning block 35 and the second positioning block 44 are used to position the first wedge block 3 and the second wedge block 4 so that the sealing ring 5 can be aligned with the through groove 11.

[0037] The top of the first wedge block 3 is provided with a connecting seat 36, the connecting seat 36 is provided with a connecting groove 37, and the bottom of the connecting rod 6 is provided with a connecting shaft 61, which is slidably connected to the connecting groove 37.

[0038] A roller seat 38 is provided on the inclined surface of the first wedge block 3, and a roller 39 is provided inside the roller seat 38. The roller 39 in the roller seat 38 is used to reduce the frictional force of the relative movement of the first wedge block 3 and the second wedge block 4.

[0039] Working principle: When the valve is opened, the power unit 2 drives the connecting rod 6 to move upward, the connecting rod 6 drives the first wedge block 3 to move upward, the pressure of the second wedge block 4 on the first wedge block 3 gradually decreases, and it moves towards the first wedge block 3 under the tension of the first spring 8. The sealing ring 5 leaves the valve body 1, and after the limiting block 41 slides to the bottom of the limiting groove 32, the second wedge block 4 moves upward with the first wedge block 3, at which point the valve is fully opened.

[0040] When the valve is closed, the power unit 2 drives the connecting rod 6 to move downward. The connecting rod 6 drives the first wedge block 3 and the second wedge block 4 to move downward. After the second positioning block 44 hits the bottom of the valve body 1, the second wedge block 4 stops moving downward. At this time, the first wedge block 3 continues to move downward and gradually increases the pressure on the second wedge block 4, so that the sealing ring 5 of the second wedge block 4 is pressed tightly against the valve body 1 to achieve a seal.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
