[0043] Reference Figure 1 , Figure 2 and Figure 3 A type of valve, consisting of a snap-fit ​​valve packing online replacement structure;

[0044] Specifically, valves with a snap-fit ​​valve packing online replacement structure can easily and quickly replace the packing, shorten downtime, improve production efficiency, and provide reliable sealing, effectively ensuring stable valve operation.

[0045] Working principle: when the packing is to be replaced, the gland 27 is pulled up, the plurality of guide bosses 2101 slide in the vertical guide grooves 2102 opened around the inner wall of the packing can 21, which limits the vertical movement of the gland 27, and at the same time, the elastic assembly 211 plays a role, the plurality of outer shells 2111 are fixed around the inner wall of the gland 27, and the slidingly connected springs 2112 are connected with the movable clamping head 29. During the pulling of the gland 27, the movable clamping head 29 slides along the fixed clamping buckle slope of the inner side clamping groove 26 of the L-shaped elastic metal sheet 25 and is separated from the clamping groove 26, so that the gland 27 is separated from the packing can 21. During the separation of the movable clamping head 29 from the clamping groove 26, the movable clamping head 29 and the guide slider 2113 on the outer wall thereof retract inward along the inner wall of the outer shell 2111, and the spring 2112 is compressed. After the movable clamping head 29 is completely separated from the clamping groove 26, the movable clamping head 29 is stretched out under the action of the spring 2112, and the old packing is directly pulled out, the new packing is loaded, the outer elastic layer 241 is elastically attached to the inner wall of the packing can 21, the medium is prevented from leaking from the gap in the inner wall, the middle reinforcing layer 242 enhances the structural strength of the packing assembly 24, improves the stability and durability, the inner sealing layer 243 directly contacts the valve stem 5, prevents the medium from leaking along the valve stem 5, the elastic compensation ring 22 can assist in filling the gap, and there is no need to compact layer by layer. After the new packing is loaded, the gland 27 is lowered into the packing can 21, at this time the movable clamping head 29 slides into the clamping groove 26 along the fixed clamping buckle slope, and the locking is completed. During the operation of the valve, when the packing is thinned due to wear, the elastic compensation ring 22 will expand to fill the gap caused by the thinning of the packing. At the same time, the L-shaped elastic metal sheet 25 as a buckle structure allows the gland 27 to sink slightly due to its own elastic deformation, thereby continuously maintaining the compression state of the packing, effectively avoiding leakage, ensuring the normal operation of the valve, and realizing the quick replacement of the packing without disassembling the bolts, shortening the downtime and improving the production efficiency.

[0046] And when the valve needs to be installed, the mounting base 34 is fixed in place by the fixing assembly 39, a plurality of fixing blocks 391 are fixed around the outer wall of the mounting base 34 respectively, the screws 392 are screwed through the washers 393 and the fixing blocks 391 and the fixed surface, the mounting base 34 is stably fixed in the corresponding position by tightening the screws 392 so that the washers 393 tightly fit the top of the fixing blocks 391, the rotating shaft 36 at the front side of the mounting base 34 is rotated, the rotating shaft 36 drives the driving bevel gear 37 fixedly connected thereto to rotate, the driving bevel gear 37 meshes with the transmission bevel ring 35 at the bottom of the adjusting table 32, when the driving bevel gear 37 rotates, the transmission bevel ring 35 rotates accordingly, and in turn drives the rotating ring 33 to rotate in the inner wall of the adjusting table 32, since the two fixed sleeve shoulders 31 are fixedly connected with the valve body 1 and the bottom is connected with the adjusting table 32, the rotation of the rotating ring 33 realizes the angle adjustment of the valve body 1 relative to the mounting base 34, meeting the demand for the angle of the valve in different installation scenarios, when the angle adjustment is completed, the angle is locked by operating the limiting assembly 38, the sleeve gear 381 is slid along the outer wall of the rotating shaft 36 until the sleeve gear 381 meshes with the limiting tooth sleeve 382 fixed at the front side of the mounting base 34, at this time, since the limiting tooth sleeve 382 is fixed, the sleeve gear 381 cannot rotate, and in turn limits the rotating shaft 36 from rotating, so as to firmly lock the angle of the valve body 1, ensuring that the valve maintains a stable installation angle during use.

[0047] Finally, when the flow size of the valve body 1 needs to be adjusted, the C-shaped limiting column 43 is pulled upward, in this process, the limiting block 44 slides along the inner wall of the limiting groove 45, since the limiting block 44 cannot escape from the restraint of the limiting groove 45, it is ensured that the C-shaped limiting column 43 cannot escape from the left sliding groove 42, when the C-shaped limiting column 43 is pulled to a certain height, the right side thereof escapes from the right sliding groove 42, at this time, the C-shaped limiting column 43 is rotated to the other side, at this time, the C-shaped limiting column 43 no longer limits the two rotating handles 41, the two rotating handles 41 are unfolded, the two rotating handles 41 are rotated to drive the valve stem 5 to rotate, the bottom end of the valve stem 5 is connected with the adjusting component in the valve body 1, the rotation of the valve stem 5 realizes the adjustment of the opening degree of the passage in the valve body 1, finally achieving the purpose of adjusting the flow size of the medium passing through the valve body 1, after the adjustment is completed, the two rotating handles 41 are folded and fitted, the other end of the C-shaped limiting column 43 is inserted into the right sliding groove 42, the limiting is completed, so that the operator can flexibly and conveniently adjust the flow of the valve body 1 according to the actual demand, and at the same time, the replacement of the packing is not hindered.

[0048] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
