Description

Technical Field

[0001] This utility model relates to the field of cable material production technology, and in particular to a convenient rotary valve for ultra-high voltage cable materials. Background Art

[0002] In the production process of ultra-high voltage cable materials, the rotary valve, as a key component for controlling fluid flow, has a significant impact on production efficiency and product quality due to its performance stability and ease of operation.

[0003] In daily use, to meet the cleanliness requirements of production equipment, rotary valves need to be cleaned periodically. Traditional rotary valves, due to the complete separation of the impeller from the housing, require the valve cover and valve core to be completely removed during the cleaning process. The disassembly operation is cumbersome, and the blades of the valve core will also wear down with daily use. Most existing valve cores are a single unit, making replacement operations cumbersome and the long-term operating cost high. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing technologies, such as the need to completely remove the valve cover and valve core during cleaning, which is cumbersome and the valve core blades will wear down with daily use. Existing valve cores are mostly a single unit, which makes replacement cumbersome and the long-term operating cost high. Therefore, a convenient rotary valve for ultra-high voltage cable materials is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable rotary valve for ultra-high voltage cable materials includes a valve body and a valve cover located at one end of the valve body.

[0007] A valve core, used to change the flow path of fluid, is located within the valve cavity of the valve body;

[0008] At least two diagonal rods are used to connect the valve body and the valve cover, wherein the valve cover is slidably sleeved on the outer wall of the two diagonal rods;

[0009] A drive rod is used to drive the valve core to rotate, and one end of the drive rod rotates through into the valve cavity.

[0010] A rotating rod is used to install the valve core, and the rotating rod is rotatably mounted on the side of the valve cover near the valve body.

[0011] In one possible design, the outer wall of the valve body is provided with a feed end and a discharge end, and the discharge end and the feed end are arranged opposite to each other.

[0012] In one possible design, two sets of mounting rings are fixedly installed at both ends of the outer wall of the valve body, and each set of mounting rings has two rings. The two sets of mounting rings are respectively fixedly sleeved on the outer walls of two diagonal rods, and bolts are installed at the ends of the diagonal rods away from the valve body.

[0013] In one possible design, the outer wall of the valve body near the valve cover has a plurality of ring-shaped No. 3 mounting holes, and the outer wall of the valve cover has a plurality of ring-shaped No. 2 mounting holes, which respectively cooperate with the plurality of No. 3 mounting holes.

[0014] In one possible design, the valve core includes a fixed ring, a valve stem, a disassembly ring, and multiple blades. The fixed ring is fixedly sleeved on one end of the outer wall of the valve stem, and the disassembly ring is sleeved on the other end of the outer wall of the valve stem. The multiple blades are arranged in a ring on the outer wall of the valve stem. Each blade includes a blade plate and a blade strip. A plate is fixedly installed at the top of the blade plate, and the blade strip is slidably installed on the outer wall of the plate.

[0015] In one possible design, the outer wall of the valve stem has multiple annularly arranged slots, and one end of each of the multiple blades is located inside the multiple slots. The fixed ring and the disassembly ring have multiple slots on their adjacent sides. The sides of the blades and blades are fitted into the corresponding slots. The blades have mounting grooves on their side near the disassembly ring. The surface of the disassembly ring has multiple first mounting holes, and the multiple first mounting holes respectively cooperate with the multiple mounting grooves.

[0016] In one possible design, a second circular groove is formed at one end of the valve stem, and a first circular groove is formed at the other end of the valve stem. A rectangular groove is formed inside the valve stem, and the two ends of the rectangular groove are connected to the second circular groove and the first circular groove, respectively. A second rectangular block is provided at the end of the rotating rod near the valve stem. The rotating rod cooperates with the second circular groove, and the second rectangular block cooperates with the rectangular groove. A first rectangular block is provided at the end of the driving rod near the valve stem. The driving rod cooperates with the first circular groove, and the first rectangular block cooperates with the rectangular groove.

[0017] In one possible design, a sealing ring is provided on the side of the valve cover near the valve body.

[0018] In this application, during actual use, mounting holes No. 2 and No. 3, and mounting groove and No. 1, are all connected and fixed by bolts. A drive mechanism using existing technology drives the drive rod to rotate, which in turn drives the valve stem to rotate. The valve stem then drives the fixing ring, blade, and disassembly ring to rotate, thereby rotating the valve core. When cleaning is required, the fixing between the valve cover and the valve body is released, and the valve cover along with the valve core is pulled out. Figure 2This facilitates cleaning of the valve core and valve cavity. When the blades need to be replaced due to wear or other issues, the fixing of the disassembly ring is released and the blade is removed. Then, the blade plate or blade strip can be pulled out from the inside of the slot and removed for individual replacement, thus facilitating cleaning, maintenance, or replacement of the valve core.

[0019] In this utility model, the portable rotary valve for ultra-high voltage cable materials, through two diagonal rods 7, allows the rotary valve to be cleaned simply by removing the valve cover and moving it along the diagonal rods, avoiding the need to move the valve cover and valve core after disassembly, reducing the workload of operators, and making the cleaning of the rotary valve more convenient.

[0020] In this utility model, the portable rotary valve for ultra-high voltage cable materials, through the detachable valve core, allows for the individual disassembly and replacement of the blades and blades when the blades are worn and need to be replaced during daily use, thereby reducing operating costs.

[0021] In this utility model, when cleaning and maintaining the valve cover by removing the fixed valve cover, it is possible to avoid moving the valve cover and valve core after disassembly, thereby reducing the workload of the operator and making the cleaning more convenient.

[0022] When the valve core needs to be replaced due to wear or other reasons, the vanes can be replaced separately, thereby reducing long-term operating costs. BRIEF DESCRIPTION OF THE DRAWINGS
