[0002] The gate valve sealing surface processing tooling is a tool specifically used for processing the gate valve sealing surface, which is used to clamp the gate valve sealing surface to improve the processing efficiency and ensure the processing accuracy.

[0003] To ensure the position accuracy and profile accuracy of the valve body during the processing, reasonable positioning blocks need to be added to the tooling. Through the cooperation of the positioning blocks and the valve body, it is ensured that the valve body will not shift or slide during the processing.

[0004] In the prior art, when processing the gate valve sealing surface, the gate valve sealing surface is clamped and fixed by the positioning blocks. After the clamping is completed, it is necessary to adjust the positions of multiple positioning blocks to facilitate the adjustment of the position of the gate valve sealing surface so that it is in a suitable position. However, when accurately adjusting the position of the gate valve sealing surface, the coordinated adjustment of multiple positioning blocks is required, resulting in a more cumbersome adjustment process and being not conducive to processing. Therefore, we propose a gate valve sealing surface processing tooling. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] By providing a processing tooling for the gate valve sealing surface in the embodiments of this application, the problem that when precisely adjusting the position of the gate valve sealing surface, the coordinated adjustment of multiple positioning blocks is required, resulting in a cumbersome adjustment process and being not conducive to processing, is solved. It is realized that the contact seat 402 drives the connection seat 401 and the moving seat 304 to move. When the moving seat 304 moves, the spring 303 pulls the moving seat 304 and the fixing unit 4 to move, so that the contact seat 402 limits the gate valve sealing surface. By adjusting the handle 305, the adjusting seat 302 is driven to move, changing the compression degree of the spring 303, and further changing the position of the gate valve sealing surface on the chute 2, facilitating the accuracy of processing. Only individual adjustment is required, without the need to adjust the positions of multiple connection seats 401 and contact seats 402, resulting in a simpler adjustment.

[0025] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0026] The embodiments of the present utility model disclose a processing tooling for the gate valve sealing surface.

[0027] According to the attached Figures 1-3 As shown, it includes a carrying platform 1, a plurality of adjusting units 3, and a plurality of fixing units 4. The plurality of adjusting units 3 are equidistantly distributed on the chute 2, and the fixing units 4 are located on the corresponding adjusting units 3.

[0028] The adjusting unit 3 includes an adjusting screw rod 301 rotatably connected to the chute 2. A moving seat 304 is slidably connected to the outer peripheral wall of the adjusting screw rod 301. Place the gate valve sealing surface on the carrying platform 1. Through the contact and extrusion between the gate valve sealing surface and a plurality of contact seats 402, at this time, the contact seat 402 drives the connection seat 401 and the moving seat 304 to move. When the moving seat 304 moves, the spring 303 pulls the moving seat 304 and the fixing unit 4 to move, so that the contact seat 402 limits the gate valve sealing surface. By adjusting the handle 305, the adjusting seat 302 is driven to move, changing the compression degree of the spring 303, and further changing the position of the gate valve sealing surface on the chute 2, facilitating the accuracy of processing. Only individual adjustment is required, without the need to adjust the positions of multiple connection seats 401 and contact seats 402, resulting in a simpler adjustment.

[0029] The fixing unit 4 includes a connecting seat 401 fixedly connected to the top end face of the moving seat 304. A contact seat 402 is fixedly connected to the outer wall of the connecting seat 401. A fixing seat 404 is slidably connected to the inner wall of the connecting seat 401. When the gate valve sealing surface is limited to a proper position, at this time, by rotating the fixing screw rod 403, the fixing seat 404 moves, so that the fixing seat 404 contacts the carrying platform 1, the position of the fixing unit 4 is limited, and the contact seat 402 fixes the gate valve sealing surface, which is convenient for processing.

[0030] A plurality of sliding grooves 2 are formed on the carrying platform 1, and the sliding grooves 2 are slidably connected to the moving seat 304. The movement of the moving seat 304 is relatively stable through the sliding grooves 2.

[0031] A spring 303 is fixedly connected to the outer wall of the moving seat 304. One end of the spring 303 far from the moving seat 304 is fixedly connected to an adjusting seat 302. The gate valve sealing surface is placed on the carrying platform 1. Through the contact and extrusion between the gate valve sealing surface and a plurality of contact seats 402, at this time, the contact seat 402 drives the connecting seat 401 and the moving seat 304 to move. When the moving seat 304 moves to stretch the spring 303, under the reaction force of the spring 303, the contact seat 402 fixes the gate valve sealing surface.

[0032] The adjusting seat 302 is threadedly connected to the outer peripheral wall of the adjusting screw rod 301. By rotating the adjusting screw rod 301, the adjusting seat 302 is driven to move, so that the position of the adjusting seat 302 moves, and then the compression degree of the spring 303 is different. Furthermore, it is convenient to adjust the positions of the moving seat 304 and the fixing unit 4, and then accurately adjust the position of the gate valve sealing surface.

[0033] One end of the adjusting screw rod 301 is fixedly connected to a handle 305. By rotating the handle 305, the adjusting screw rod 301 is driven to rotate.

[0034] A positioning groove 405 is formed on the inner wall of the fixing unit 4. The fixing seat 404 is slidably connected to the positioning groove 405. Under the action of the positioning groove 405, the movement of the fixing seat 404 is relatively stable.

[0035] The top end face of the fixing seat 404 is rotatably connected to a fixing screw rod 403.

[0036] The fixing screw rod 403 is threadedly connected to the inner wall of the connecting seat 401. By rotating the fixing screw rod 403 to rotate along the connecting seat 401, under the rotation of the fixing screw rod 403, the fixing seat 404 moves to contact the carrying platform 1, the position of the fixing unit 4 is limited, and the contact seat 402 fixes the gate valve sealing surface, which is convenient for processing.

[0037] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only to illustrate the principle of the present utility model.
