[0035] See also Figure 5 and Figure 6 A partition plate 3 is installed in the middle of the valve housing 1, and multiple groups of water holes are opened in the middle of the partition plate 3 from the inside to the outside. The water hole groups are composed of multiple circular through holes 4 evenly distributed in the circumferential direction, and the number of circular through holes 4 in the multiple groups of water hole groups gradually increases from the inside to the outside.

[0036] See also Figure 1 , Figure 3 , Figure 5 , Figure 7 , Fig. 9 and Fig.10 The industrial valve also includes an adjusting device 5, which is connected to the partition plate 3. The adjusting device 5 includes an adjusting mechanism 51 arranged above the partition plate 3. A plurality of coaxially distributed connecting rings 52 are arranged near the lower end of the outer periphery of the adjusting mechanism 51. The plurality of connecting rings 52 have the same structure and the diameter gradually increases from the inside to the outside. A plurality of circumferentially uniformly distributed connecting strips 53 are installed between two adjacent connecting rings 52. The lower ends of the plurality of connecting rings 52 are all connected with a plurality of circumferentially uniformly distributed sealing mechanisms 54. The distribution positions of the plurality of sealing mechanisms 54 correspond to the distribution positions of the plurality of circular through holes 4 one by one. The sealing mechanisms 54 are plug-fitted with the corresponding circular through holes 4.

[0037] During specific operation, the valve housing 1 and the valve cover 2 are initially in a separated state, and the sealing mechanisms 54 on different connecting rings 52 are adjusted manually. The sealing mechanisms 54 cooperate with the corresponding circular through holes 4, and the functions of sealing and opening the circular through holes 4 can be achieved by adjusting the adjusting mechanism 51.

[0038] See also Figure 5 and Figure 6The sealing mechanism 54 includes a threaded rod 541 installed at the lower end of the corresponding connecting ring 52 and located in the corresponding circular through hole 4. The threaded rod 541 is threadedly connected with multiple filling rings 542 from top to bottom. The filling ring 542 is connected with a filling branch chain 543. The lower end of any one of the filling branch chains 543 is connected to multiple pushing rods 544 evenly distributed in the circumference.

[0039] In the specific operation, a plurality of filling rings 542 are manually selected before use, and the plurality of filling rings 542 are sequentially threadedly connected to the plurality of threaded rods 541 until the plurality of threaded rods 541 are all connected with the same number of filling rings 542 as the number of water hole groups, and one of the plurality of filling rings 542 installed on the threaded rods 541 must be provided with a plurality of pushing rods 544 through a filling branch chain 543, and the filling ring 542 with the pushing rod 544 on the innermost plurality of threaded rods 541 is located at the first position from top to bottom, close to the innermost plurality of threaded rods 541. The filling rings 542 with pushing rods 544 on the multiple threaded rods 541 of the rod 541 are located at the second position from top to bottom, and so on, the filling rings 542 with pushing rods 544 on the multiple threaded rods 541 distributed from inside to outside are positioned successively lowered on the corresponding threaded rods 541, and the multiple filling rings 542 can also be installed on only a few of the threaded rods 541. There are multiple circular through holes 4 that are always in an open state, thereby changing the range of flow regulation of the valve, effectively increasing the flexibility of valve use, and being suitable for different flow regulation occasions.

[0040] See also Figure 1 , Figure 5 , Figure 7 and Figure 8 The adjusting mechanism 51 comprises a circular plate 511 installed on the inner ring surface of the innermost connecting ring 52, the upper end of the circular plate 511 is rotatably connected with an adjusting screw 512, the outer surface of the adjusting screw 512 is threadedly connected with a threaded sleeve 513, the upper end of the threaded sleeve 513 is fixedly connected to the lower end of the top wall of the valve cover 2, a plurality of lifting through holes 514 evenly distributed in the circumferential direction are opened on the wall of the adjusting screw 512 near the lower end, the upper end of the adjusting screw 512 passes through the top wall of the valve cover 2 and is provided with a handle.

[0041] In specific operation, after a plurality of filling rings 542 are connected to the corresponding threaded rods 541, the valve cover 2 is installed on the upper end of the valve housing 1 by means of bolts. During the installation of the valve cover 2, the valve cover 2 drives the plurality of connecting rings 52 to move into the interior of the valve housing 1 through the adjusting mechanism 51, and the plurality of connecting rings 52 drive the plurality of filling rings 542 to move downward through the plurality of threaded rods 541 and insert into the corresponding circular through holes 4 (such as Fig.11As shown), until the valve cover 2 covers the upper end of the valve housing 1, the multiple filling rings 542 located at the top are plugged into and matched with the multiple circular through holes 4 to achieve the function of sealing the circular through holes 4, and then the valve housing 1 is installed between the two existing pipes.

[0042] By turning the adjusting screw tube 512 by the handle, the adjusting screw tube 512 drives the innermost connecting ring 52 to rise through the circular plate 511, and the innermost connecting ring 52 drives the remaining connecting rings 52 to rise at the same time through the multiple connecting strips 53, and the multiple rising connecting rings 52 drive the multiple threaded rods 541 to rise, and the multiple threaded rods 541 drive the corresponding multiple filling rings 542 to rise. When the multiple threaded rods 541 rise to a distance consistent with the height of the filling rings 542, the filling ring 542 located at the top is separated from the corresponding circular through hole 4, and the multiple threaded rods 541 located at the innermost side drive the corresponding pushing rods 544 to move into the innermost multiple circular through holes 4 through the multiple filling rings 542 at the top, and the multiple threaded rods 541 at the remaining positions drive the corresponding second filling ring 542 to move into the remaining circular through holes 4 to continue to block the remaining circular through holes 4. To realize the function of opening the innermost circular through hole 4, the multiple threaded rods 541 continue to rise to a distance consistent with the height of the filling ring 542. During this process, the multiple threaded rods 541 located at the innermost side drive the multiple corresponding second filling rings 542 to rise and seal the multiple innermost circular through holes 4. The multiple threaded rods 541 close to the innermost multiple threaded rods 541 drive the corresponding pushing rods 544 to move into the multiple circular through holes 4 close to the innermost multiple circular through holes 4 through the corresponding multiple second filling rings 542, thereby opening the corresponding circular through holes 4. Similarly, as the rising height of the threaded rods 541 increases, the number of opened circular through holes 4 increases, thereby realizing multi-stage regulation of water flow, and the flow regulation has high accuracy. According to the actual water flow demand, the adjusting screw 512 is rotated to the required height to open the corresponding number of circular through holes 4 (such as Fig.13 shown).

[0043] See also Figure 5 , Figure 6 , Fig. 9 and Fig.10The filling branch chain 543 includes an annular cavity 5431 opened inside the filling ring 542, an annular groove 5432 is opened at the upper and lower ends of the filling ring 542, and a pushing ring 5433 is slidably connected in the annular groove 5432. Two sliding rods 5434 are symmetrically installed at the opposite ends of the two pushing rings 5433. The opposite ends of the sliding rods 5434 slide through the filling ring 542 and are located inside the annular cavity 5431. A tightening ring 5431 is installed between the four sliding rods 5434. 435, the cross section of the tightening ring 5435 is a right-angled trapezoid with the inclined surface facing outward, a baffle film 5436 is installed in the annular groove 5432, and the baffle film 5436 is fixedly connected to the sliding rod 5434, a sealing ring 5437 is installed in the middle of the outer ring wall of the filling ring 542, the inner ring surface of the sealing ring 5437 is located in the annular cavity 5431 and is integrally formed with a raised ring with a right-angled triangle cross section, the slope of the raised ring faces inward, and the upper ends of the plurality of pushing rods 544 are fixedly connected to the corresponding pushing rings 5433.

[0044] See also Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.12 , a plurality of the connecting rings 52 are commonly connected with a clamping mechanism 55, the clamping mechanism 55 includes a plurality of coaxially distributed clamping rings 551 arranged above the plurality of the connecting rings 52, the distribution positions of the plurality of the clamping rings 551 correspond one-to-one with the distribution positions of the plurality of the connecting rings 52, a plurality of circumferentially uniformly distributed connecting rods 552 are installed between two adjacent clamping rings 551, a plurality of circumferentially uniformly distributed pressing groups are installed at the lower ends of the plurality of the clamping rings 551, the positions of the plurality of the pressing groups correspond one-to-one with the positions of the plurality of the circular through holes 4, the pressing groups are composed of two symmetrically distributed pressing rods 553, the lower ends of the pressing rods 553 slide through the corresponding connecting rings 52 and contact with the filling branches 543 at the corresponding positions.

[0045] See also Figure 5 , Figure 7 , Figure 8 and Fig. 9 The adjusting mechanism 51 is connected with a tightening mechanism 56, and the tightening mechanism 56 includes a cylindrical rod 561 slidably connected to the inside of the adjusting screw tube 512, and a plurality of circumferentially evenly distributed lower pressure strips 562 are installed on the outer surface of the cylindrical rod 561 near the lower end, and the lower pressure strips 562 slide through the lifting through hole 514, and a limiting hole 563 is provided at the upper end of the cylindrical rod 561, and a limiting branch chain 564 is provided on one side of the upper end of the cylindrical rod 561, and the limiting branch chain 564 is connected to the handle, and the limiting branch chain 564 includes a limiting plate 5641 installed at the upper end of the handle, and a T-shaped limiting rod 5642 in a horizontal state is slidably penetrated and connected in the middle of the limiting plate 5641.

[0046] In specific operation, after the flow regulation of the valve is completed, the cylindrical rod 561 is pressed downward, and the cylindrical rod 561 drives the multiple pressing strips 562 to move downward and press the multiple clamping rings 551 downward. The multiple clamping rings 551 are forced to drive the multiple pressing groups to move downward. The pressing rods 553 in the multiple pressing groups penetrate the corresponding connecting rings 52 and push the pushing rings 5433 at the corresponding positions. The pushing rings 5433 are forced to drive the tightening rings 5435 to move downward through the sliding rods 5434. The tightening rings 5435 that move downward push the convex parts on the sealing rings 5437. The ring is lifted and pushed, and the sealing ring 5437 is forced to expand outward. At the same time, the tightening ring 5435 drives the corresponding pushing ring 5433 to move downward through the sliding rod 5434 located below it. If multiple pushing rods 544 are installed below this pushing ring 5433, the multiple pushing rods 544 are driven to move downward. The multiple pushing rods 544 drive the pushing ring 5433 below them to move downward and repeat the expansion action of the sealing ring 5437. If there is another pushing ring 5433 below this pushing ring 5433, the pushing ring 5433 below is driven to move downward and The expansion action of the sealing ring 5437 is repeated, and the expansion action of the sealing ring 5437 on the same threaded rod 541 is performed simultaneously. After the sealing ring 5437 in the circular through hole 4 expands, the friction between the sealing ring 5437 and the hole wall of the circular through hole 4 is increased, and the strength of the sealing ring 5437 and the hole wall of the circular through hole 4 is increased, thereby further improving the sealing performance of the circular through hole 4, avoiding water leakage in the circular through hole 4 after sealing, and partial wear of the sealing ring 5437 after long-term use will not affect the sealing performance, and can still effectively improve It provides a sealing effect and extends the service life of the valve. When the sealing ring 5437 expands, the cylindrical rod 561 drives the limiting hole 563 to move to the end of the T-shaped limiting rod 5642, pushing the T-shaped limiting rod 5642. The T-shaped limiting rod 5642 is inserted into the limiting hole 563 to realize the function of limiting the cylindrical rod 561. If the flow of the valve needs to be adjusted, just pull the T-shaped limiting rod 5642 out of the limiting hole 563, and the squeezed sealing ring 5437 will automatically reset through its own elasticity to avoid affecting the adjustment.

[0047] See also Figure 5 Two buffer mechanisms 57 are symmetrically connected to the lower end of the horizontal section of the partition plate 3. The buffer mechanism 57 includes a buffer sleeve 571 installed at the lower end of the horizontal section of the partition plate 3. A telescopic rod 572 is installed at the lower end of the top wall of the buffer sleeve 571. A lifting plate 573 slidably connected to the inner wall of the buffer sleeve 571 is installed at the lower end of the telescopic rod 572. A buffer spring 574 is installed between the upper end of the lifting plate 573 and the lower end of the top wall of the buffer sleeve 571. An arc-shaped groove is opened at the lower end of the lifting plate 573.

[0048] During specific operation, when the flow of the valve is adjusted, the lifting plate 573 contacts the water flow through the arc groove, and the water flow impacts the lifting plate 573. The lifting plate 573 absorbs the impact force of the water flow through the buffer spring 574, avoiding excessive pressure inside the valve housing 1, thereby increasing the service life of the industrial valve.
