Description

Technical Field

[0001] This utility model relates to the technical field of glass bending and tempering equipment, and in particular to a double-opening gate valve for a glass bending air supply system. Background Technology

[0002] In existing technology, glass is heated and softened before entering the curved air grid and being bent into shape. The bent glass needs to be rapidly quenched and shaped in situ before it can be continuously output from the furnace.

[0003] When each piece of glass is bent into shape, the corresponding gate valve needs to be closed to prevent the air supply system from outputting quenching air to the curved air grid. However, when each piece of glass is quenched and shaped in situ, the gate valve must be opened to allow the air supply system to quickly input quenching air to the curved air grid. The interval between the opening and closing of the gate valve is short. If the existing single-plate gate valve is used in the air supply duct, the opening and closing time of the single-plate gate valve is long, which makes it difficult to meet the process requirements and will reduce production efficiency.

[0004] Since the fan is in a pressure-maintaining state when the gate valve is closed, the fan's air pressure exerted on the gate valve at the moment the gate valve is opened is relatively large and has a certain impact force, which can easily cause the gate of the gate valve to deform due to pressure. Utility Model Content

[0018] The rear end of the anti-collision plate extends rearward and wraps around the edge of the rear end face on the other side of the gate; the rear end face of the anti-collision plate abuts against the rear inner wall of the sliding channel.

[0020] The upper limit plate is installed on the top of the sliding channel, and the bottom surface of the upper limit plate is provided with an upper limit groove. The groove opening faces downward and the upper limit groove extends along the length direction of the sliding channel.

[0021] The tops of the two gates are housed in the upper limit groove, and the bottom surface, front wall surface and rear wall surface of the upper limit groove are respectively fitted with the top surface, front plate surface and rear plate surface of the gate.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] A double-opening gate valve 1 is provided with flanges 11 on both its front and rear faces. The double-opening gate valve 1 includes two gates 12, two actuators 13, multiple support rods 14 and multiple first pulleys 15.

[0042] The double-opening gate valve 1 is provided with a sliding channel 10; the sliding channel 10 extends in the left and right direction; the sliding channel 10 is located between the two flanges 11; the two gates 12 are arranged opposite each other in the sliding channel 10;

[0043] The actuator 13 is mounted on the left or right outer side of the double-opening gate valve 1, with the two actuators 13 facing each other. The output end of the actuator 13 extends into the sliding channel 10 and is connected to one side of the corresponding gate 12.

[0044] Multiple support rods 14 are erected at intervals between the flange 11 and the sliding channel 10 in front; two first pulleys 15 are fitted onto the outer circumferential surfaces of the support rods 14, one above the other; the outer circumferential surfaces of the first pulleys 15 are used to slide against the front surface of the corresponding gate 12.

[0045] Figure 4 This is a schematic diagram of the installation structure of a double-opening gate valve in an air supply system according to an embodiment of the present invention. The double-opening gate valve 1 is installed in the middle of the air supply duct 4. The flange 11 at the front end is connected to the inlet of the air collection box 2 through the air supply duct 4, and the flange 11 at the rear end is connected to the outlet of the fan 3 through the air supply duct 4. Figures 1-3 This is a schematic diagram of the structure of the double-opening gate valve 1 of this utility model.

[0046] like Figures 1-4 As shown, when it is necessary to send quenching air forward through the air collection box 2 to the curved wind grid in order to quench the curved steel glass and to shape the curved steel glass in the curved wind grid, the two actuators 13 start simultaneously and pull the two gates 12 in the closed double-open gate valve 1 away from each other. The front plate surfaces of the two gates 12 slide against the multiple first pulleys 15 located on the multiple support rods 14, so that the two gates 12 can quickly open the double-open gate valve 1, which can prevent the gates 12 from deforming due to wind pressure during operation.

[0047] Furthermore, a plurality of second pulleys 19 are installed in the sliding channel 10 located below;

[0048] Multiple second pulleys 19 are arranged at intervals on the left and right; the top surface of the second pulley 19 is used to support the bottom surface of the corresponding gate 2.

[0049] like Figure 1 and Figure 3 As shown, by supporting the bottom surfaces of the two gates 2 with multiple second pulleys 19, the rigid friction between the bottom surfaces of the two gates 2 and the sliding channel 10 can be reduced, thereby further improving the service life and smoothness of opening and closing of the two gates 2.

[0050] Furthermore, a crash barrier 121 is installed on the other side of the gate 12;

[0051] The anti-collision plate 121 is erected, and the side of the anti-collision plate 121 abuts against the side of the other side of the gate plate 12.

[0052] like Figure 2 As shown, a crash plate 121 is installed on the side of the gate 12 away from the driver 13 to avoid rigid collision when the two gates 121 are closed, which can reduce noise and improve the service life of the gate 12.

[0053] Furthermore, the double-opening gate valve 1 also includes two vertically arranged front limiting plates 16;

[0054] The two front limiting plates 16 are fixed in the sliding channel 10 with a left and right distance, and are located on the left and right sides of the flange 11 respectively; the front plate surface of the front limiting plate 16 abuts against the front inner wall surface of the sliding channel 10, and the rear plate surface of the front limiting plate 16 abuts against the front plate surface of the corresponding gate 12.

[0055] The rear end of the anti-collision plate 121 extends rearward and wraps around the edge of the rear end face of the other side of the gate 12; the rear end face of the anti-collision plate 121 abuts against the rear inner wall of the sliding channel 10.

[0056] like Figure 2 As shown, the front limit plate 16 and the anti-collision plate 121 limit the front and rear movements of the gate 12, thereby preventing the gate 12 from swaying back and forth and further improving the operational stability of the double-opening gate valve 1.

[0057] Furthermore, the double-opening gate valve 1 also includes an upper limit plate 17 and a lower limit plate 18;

[0058] The upper limit plate 17 is installed on the top of the sliding channel 10. The bottom surface of the upper limit plate 17 is provided with an upper limit groove 171. The groove opening of the upper limit groove 171 faces downward and the upper limit groove 171 extends along the length direction of the sliding channel 10.

[0059] The tops of the two gate plates 12 are housed in the upper limit groove 171, and the bottom surface, front wall surface and rear wall surface of the upper limit groove 171 are respectively fitted with the top surface, front plate surface and rear plate surface of the gate plate 12 with clearance.

[0060] The top of the front limiting plate 16 avoids the upper limiting plate 17;

[0061] The lower limit plate 18 is installed at the bottom of the sliding channel 10. The top surface of the lower limit plate 18 is provided with a lower limit groove 181. The groove of the lower limit plate 18 faces upward. The lower limit plate 18 extends along the length direction of the sliding channel 10.

[0062] The bottoms of the two gate plates 12 are housed in the lower limiting groove 181, and the bottom surface, front wall surface and rear wall surface of the lower limiting groove 181 are respectively fitted with the bottom surface, front plate surface and rear plate surface of the gate plate 12 with clearance.

[0063] The lower limit plate 18 avoids the second pulley 19.

[0064] like Figure 3As shown, the upper limit plate 17 and the lower limit plate 18 can prevent the gate 12 from moving up and down and shifting, thereby further improving the operational stability of the double-opening gate valve 1.

[0065] Preferably, the anti-collision plate 121, the front limiting plate 16, the upper limiting plate 17 and the lower limiting plate 18 are made of heat-resistant nylon.

[0066] Heat-resistant nylon has good impact resistance and heat aging resistance, which can improve the service life of the anti-collision plate 121, the front limit plate 16, the upper limit plate 17 and the lower limit plate 18.

[0067] Preferably, both the first pulley 15 and the second pulley 19 are deep groove bearings.

[0068] Deep groove bearings have good service life and rotational stability.

[0069] Furthermore, this utility model proposes a curved steel air supply system, including an air collection box 2, a fan 3, an air supply duct 4, a curved air grid, a support device, and a double-opening gate valve as described above.

[0070] The double-open gate valve 1 is installed on the air supply duct 4. The flange 11 at the front end of the double-open gate valve 1 is connected to the inlet of the curved air grid through the air supply duct 4 and the air collection box 2. The flange 11 at the rear end of the double-open gate valve 1 is connected to the outlet of the fan 3 through the air supply duct 4.

[0071] The support device consists of multiple support rods 4 and multiple first pulleys 5, and provides sliding support for the front end faces of the two gates 12 in the double-opening gate valve 1.

[0072] like Figures 1-4 As shown, the curved steel air supply system of this utility model includes a support device consisting of multiple support rods 4 and multiple first pulleys 5, which can ensure the opening and closing stability of the double-open gate valve 1 in the air supply duct 4 and prevent the gate 12 from deforming due to wind pressure, so that the curved steel air supply system can meet the production process requirements of continuous sheet production and has good operational stability.

[0073] In summary, such as Figures 1-4 The embodiment of the present invention shown in the figure has a double gate valve. With the support of the first pulley 15 on the support rod 14 and driven by the two drivers 13, the two gates 12 can quickly open and close the double gate valve 1. It can also prevent the gates 12 from deforming due to wind pressure, and has good operational stability and service life.
