Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and specifically relates to a tilting valve. Background Technology

[0002] Vacuum coating equipment typically includes several interconnected chambers. Each chamber has a reversible valve plate at its inlet and outlet to open / close it. One of these chambers is a transition chamber that requires repeated vacuum breaking. One side of this chamber is connected to the ambient pressure environment, while the other side is connected to the process chamber, which is always under vacuum. The valve plate on the side connected to the ambient pressure environment needs to withstand more pressure. During the repeated opening and closing of the valve plate by the drive mechanism, the angle of the closed valve plate can easily change, causing the chamber to fail to seal properly and thus affecting the coating efficiency.

[0003] Therefore, how to prevent the valve plate from changing its angle after closing, thus causing the chamber to fail to seal properly, is a technical problem that urgently needs to be solved in this field.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0032] Research has revealed that in the prior art, the initial angle of the valve plate changes after repeated opening and closing. This results in insufficient pressure on the opening of the coating cavity or gaps when the drive mechanism drives the valve plate to the end point, causing the coating cavity to fail to seal properly. This is the problem and objective that the utility model aims to solve.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] See Figures 1 to 3This paper illustrates a flip valve, comprising: a base 1 on which a drive mechanism 2 is mounted; a valve plate 3 with a rotating shaft 31 on its side wall, an adjusting disc 32 at the end of the rotating shaft 31, the adjusting disc 32 having several through slots 32a, the through slots 32a being connected to the output shaft of the drive mechanism 2 by bolts to flip the valve plate 3; and the through slots 32a being oblong to adjust the angle of the adjusting disc 32. In short, by opening oblong through slots 32a on the adjusting disc 32, when the angle of the valve plate 3 changes after closing, the bolts on the adjusting disc 32 are loosened, the adjusting disc 32 is adjusted to a suitable angle, and then the bolts are tightened to adjust the angle of the valve plate 3, so that after the drive mechanism 2 drives the valve plate 3 to close, the coating cavity 4 can be stably sealed.

[0038] In some embodiments, the axis array of the through groove 32a ring adjustment disk 32 is arranged, and the adjustment disk 32 is coaxially arranged with the output shaft of the drive mechanism 2; in short, this design can ensure that the valve plate 3 only changes its angle before and after adjustment, and ensure that the valve plate 3 can fit well with the opening of the coating cavity 4.

[0039] In some embodiments, the output shaft of the drive mechanism 2 is coaxially provided with a transition flange 21a, the adjusting disc 32 is coaxially provided with the transition flange 21a, and the through groove 32a is connected to the transition flange 21a by bolts; and at least two bolts are provided in each through groove 32a; in short, the through groove 32a and the transition flange 21a are connected by bolts to complete the connection between the rotating shaft 31 and the output shaft of the drive mechanism 2, and at least two bolts are provided in the through groove 32a to ensure the connection strength between the adjusting disc 32 and the transition flange 21a.

[0040] In some embodiments, the opening of the through groove 32a is provided with a countersunk groove 32b to embed the head of the bolt; in short, the opening of the through groove 32a is provided with a countersunk groove 32b so that the head of the bolt will not protrude from the adjusting disc 32 and avoid interference with other components.

[0041] In some embodiments, the end of the rotating shaft 31 extends out of the adjusting plate 32; the axis of the adapter flange 21a is provided with a through hole 21b, and both ends of the rotating shaft 31 are inserted into the through hole 21b; in short, the two ends of the rotating shaft 31 are inserted into the through hole 21b so that after the bolts connecting the adjusting plate 32 and the adapter flange 21a are loosened, the rotating shaft 31 can only change its angle, ensuring that the valve plate 3 can stably seal the opening of the coating chamber 4 after adjustment.

[0042] In some embodiments, the rotating shaft 31 is disposed on the side of the valve plate 3 near the coating cavity 4; in short, since the valve plate 3 is always attracted to the coating cavity 4 after it is closed, this design can avoid the valve plate 3 always having a force away from the rotating shaft 31, that is, avoid the bolts on the connecting seat 33 generating an outward pulling force, thereby improving the stability of use.

[0043] In some embodiments, the rotating shaft 31 is provided with a plurality of connecting seats 33, and the connecting seats 33 are provided with connecting holes 33a. The connecting holes 33a are connected to the valve plate 3 by bolts. In short, the rotating shaft 31 and the valve plate 3 are connected by connecting seats 33, which is simple and reliable.

[0044] In some embodiments, the connecting seat 33 is provided with a insertion hole 33b, the rotating shaft 31 is inserted into the insertion hole 33b, and the sidewall of the rotating shaft 31 and the sidewall of the insertion hole 33b are provided with matching flat parts 33c to transmit torque; in short, the connecting seat 33 is sleeved on the rotating shaft 31 through the insertion hole 33b, and the rotating shaft 31 and the insertion hole 33b are respectively provided with flat parts 33c, so that the rotating shaft 31 can drive the connecting seat 33 to rotate, thereby realizing the flipping of the valve plate 3.

[0045] In some embodiments, the drive mechanism 2 includes a pair of support frames 22 and a pair of rotary cylinders 21; the support frames 22 are mirror images of the top of the base 1, the rotary cylinders 21 are disposed on the side wall of the support frames 22, the output shaft of the rotary cylinders 21 extends out of the support frames 22, and the adjusting discs 32 are respectively connected to the output shafts of the rotary cylinders 21; in short, rotary cylinders 21 are provided on both sides of the rotating shaft 31, and the two rotary cylinders 21 work synchronously to reduce the torsional deformation of the rotating shaft 31, thereby reducing the pressure on the opening of the valve plate 3 and the coating cavity 4, and improving the overall service life of the flip valve.

[0046] In some embodiments, a lifting seat 11 is provided on the top of the base 1; the support frame 22 is an "L"-shaped support plate, and the horizontal surface of the support frame 22 is bolted to the top of the lifting seat 11; the rotary cylinder 21 is provided on the vertical surface of the support plate; in short, the base 1 is installed on the coating equipment, and a lifting seat 11 is provided to match the height of the support frame 22 with the opening of the coating cavity 4.

[0047] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0049] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0050] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0051] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
