In order to explain the technical characteristics of this creation in detail, the following preferred embodiments are described below in conjunction with the schematic description, in which: As shown in FIGS. 1 to 10, a gate valve 10 with a dustproof function provided by a preferred embodiment of the present invention is mainly composed of a housing 11, a slide 21, a driver 31, a swing arm 35 and a dustproof The tube 41 is composed of: the housing 11 has a flat shape, and has a first plate 13 and a second plate 15, and the housing 11 has an accommodating space 111 in the first plate 13 and the second板15之间。 Between the plate 15. The first plate 13 and the second plate 15 both face through a valve port 131, 151, and the housing 11 is provided with a guide rail group 12, which is substantially linear but has a curved portion 121 at one end.

The sliding seat 21 has a base 22 and a valve member 27, the seat body 22 is movably disposed in the housing 11 and has a driving chute 23, the valve member 27 is movably disposed in the seat body 22, And the valve member 27 has a pulley set 28 which is slidably disposed on the guide rail set 12 and is located in the housing 11, the slide seat 21 is driven by the assembly of the pulley set 28 and the guide rail set 12 Relationship between a first position P1 and a second position P2, and when the slide 21 is at the first position P1, the pulley set 28 enters the curved portion 121 and drives the valve member 27 to be perpendicular to The linear extension direction of the guide rail group 12 moves to the first plate 13 and closes the valve port 131 of the first plate 13.

The driver 31 is provided in the casing 11. In this embodiment, the driver 31 is a handle, which can be rotated by human operation. However, in actual implementation, a pneumatic device such as an air cylinder or an electric device such as a motor can also be used as a driver.

The swing arm 35 is connected to the driver 31 at one end, and has a slider 36 at the other end and is located in the drive slot 23. The driver 31 is operated to drive the other end of the swing arm 35 to perform circular motion. The slider 36 moves along the driving chute 23 to act on the groove wall of the driving chute 23, thereby driving the sliding base 21 to move.

The dust tube 41 is disposed on the seat body 22, and when the slide seat 21 is at the second position P2, the dust tube 41 is corresponding to the valve port 131 of the first plate 13 and the valve port of the second plate 15 Between 151, the valve ports 131, 151 of the first plate 13 and the second plate 15 are spatially penetrating the dust tube 41, and the wall of the dust tube 41 is located between the first plate 13 and the second plate 15 at the edges of the valve ports 131, 151, and the valve ports 131, 151 of the first plate 13 and the second plate 15 are separated from the accommodating space 111, in addition, the two end edges of the dust tube 41 are separated from the first plate 13 And the second plate 15 is separated by a predetermined distance leaving a gap S. In this embodiment, the dust pipe 41 is provided on the seat body 22 by a dust rack 45, the outer wall of the dust pipe 41 has an insertion groove 42, and the dust rack 45 has a flange 46, the dust pipe 41 is inserted into the flange 46 with its insertion groove 42. In addition, the dust-proof frame 45 extends two extension arms 47 away from the seat body 22. The two extension arms 47 are located on both sides of the dust-proof tube 41, and a roller 471 is provided at the end of the two extension arms 47. When the sliding seat 21 is at the first position P1, the rollers 471 of the two extension arms 47 abut against the plate surface of the first plate 13.

When the dust tube 41 is actually implemented, it can be seen from FIGS. 2 to 5 that it is a ring-shaped tube body, with both ends facing the first plate 13 and the second plate 15, and the end edges of the dust tube 41 are connected A shoulder 43 extends radially outward. This shoulder 43 can increase the depth of the gap S between the two valve ports 131, 151 and the dust tube 41, making it more difficult for dust to enter the housing 11 through the gap S. The shoulder portion 43 can be determined whether to be installed according to requirements. The dust tube 41 can also achieve the dust-proof effect without the shoulder portion 43. Therefore, the shoulder portion 43 may not be provided.

The above explains the structure of this creation, and then the operation status of this creation.

As shown in FIGS. 2 to 6, when the valve port 131 of the first plate 13 is to be closed, the actuator 31 is operated to rotate the swing arm 35 to drive the slider 21 to the first position P1. , Because the pulley group 28 of the valve member 27 enters the curved portion 121 and drives the valve member 27 to be perpendicular to the guide rail group 12 The linearly extending direction moves, so that the valve member 27 moves to the first plate 13 in a direction perpendicular to the guide rail group 12, and closes the valve port 131 of the first plate 13. In this closed state, air or dust cannot pass through the valve port 131 of the first plate 13. As for whether the seat body 22 moves in the direction perpendicular to the guide rail group 12 along with the valve member 27, this is a conventional technology and will not be repeated here. In addition, under certain conditions, if the state in which the creation is used is to place the creation with the valve member 27 facing down, the dust tube 41 may be affected by gravity and cause the two extension arms 47 to sag, When a sag condition occurs, the roller 471 provided at the end of the two extending arms 47 can provide an effect of resisting the first plate 13, thereby ensuring that the dustproof frame 45 does not contact the first plate 13.

As shown in FIGS. 7 to 10, when the valve port 131 of the first plate 13 is to be opened, the actuator 31 is operated to rotate the swing arm 35 to drive the slider 21 to the second position P2. At this time, the valve member 27 moves away from the valve ports 131, 151 of the first plate 13 and the second plate 15, and the dust tube 41 moves between the valve ports 131, 151 of the first plate 13 and the second plate 15 , So that the valve ports 131 and 151 of the first plate 13 and the second plate 15 spatially penetrate the dust tube 41, so that the same gate valve as the conventional gate valve without the dust tube 41 can be formed when it is opened status. Since the wall of the dustproof tube 41 is located at the edges of the valve ports 131, 151 of the first plate 13 and the second plate 15, the valve ports 131, 151 of the first plate 13 and the second plate 15 and the accommodating space 111 is separated from each other. Therefore, the dust passing through the valve port 131 of the first plate 13, the dust tube 41, and the valve port 151 of the second plate 15 cannot easily pass between the first plate 13 and the second plate 15. The space falls into the housing 11, thereby achieving the dustproof effect.

In addition, since both end edges of the dust tube 41 are separated from the first plate 13 and the second plate 15 by a predetermined distance to leave the gap S, it can be ensured that the dust tube 41 is moving to the first plate 13 Between the valve ports 131 and 151 of the second plate 15, there will be no component collision or noise, and although this gap S may allow dust to enter the interior of the housing 11, however, compared with the conventional technology In other words, the amount of dust is very small. In actual manufacturing, by reducing the gap S by increasing the assembly precision, the amount of dust dropped can be further reduced.

As can be seen from the above, this creation can completely close the valve port 131 of the first plate 13 when it is closed, and can block the gap S between the two valve ports 131, 151 and the gate valve housing 11 with a dust tube 41 when opening, By blocking the dust, it is not easy to enter the gate valve to achieve the effect of dust prevention.
