Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The embodiment of the utility model provides a valve body sealing positioning oil filling pipe structure, and the structure of the embodiment of the utility model comprises a valve body 1 and an oil filling pipe 2 as shown in fig. 1-3, wherein the valve body 1 is a mechanical sealing valve, for example. As shown in fig. 1, the valve body 1 is provided with a positioning boss ①, a fastening structure ②, and a seal ring ③. Wherein the width of the positioning boss ① -6 mm, the inner diameter of the fastening structure ② is phi 62-63 mm, and the outer diameter of the sealing ring ③ is phi 56.5-57.5 mm. The positioning boss ① is a square boss, and 4 fastening structures ② are provided.
As shown in fig. 2, the filler tube 2 is provided with a positioning groove ④, a flanging structure ⑤, and a filler tube inner wall sealing surface ⑥ for assembling a sealing ring ③. Wherein the width of the positioning groove ④ is 6-6.5 mm, the outer diameter of the flanging structure ⑤ is phi 63-63.5 mm, and the inner diameter of the oil filling pipe 2 is phi 56-56.3 mm. The sealing ring ③ is made of rubber, has good elasticity and sealing effect, and is assembled on the outer diameter of the valve body 1.
During the process of loading the valve body 1 into the oil filling pipe 2, the positioning boss ① is blocked into the positioning groove ④ to prevent the valve body 1 from rotating; the fastening structure ② of the valve body 1 is clamped on the flanging structure ⑤ of the oil filling pipe 2 to prevent the valve body 1 from falling off axially; the sealing ring ③ on the valve body 1 is tightly matched with the sealing surface ⑥ on the inner wall of the oil filling pipe, so that the assembly tightness of the product is realized.
