Description

Technical Field

[0001] This utility model relates to the field of disc valve structure, and in particular to a tooling for the electric conversion of manual disc valves. Background Technology

[0002] In hydropower facilities, oil, gas, and water pipeline systems play a crucial role in power transmission, cooling and lubrication, and system control. These systems commonly use disc valves as control devices for fluid flow. These disc valves are typically opened and closed by manually rotating the valve disc (i.e., handwheel). During rotation, it often takes several rotations to switch the valve's open and closed states, resulting in a heavy operational burden and low efficiency. Furthermore, the operating torque increases exponentially with the pipeline diameter (e.g., 150 N·m for a DN300 disc valve), requiring high torque and making manual operation difficult, which inconveniences maintenance work. Utility Model Content

[0003] To overcome the problems of high operational burden, low efficiency, and high torque requirements caused by the complete reliance on manual rotation for opening and closing disc valves in the aforementioned background technology, this utility model provides a tooling for the electric conversion of manual disc valves. By modifying the original manual valve disc, it enables it to be rotated by an electric output device. It has the beneficial effects of easy installation, wide adaptability, simple operation, saving time and effort, and greatly improving operating efficiency.

[0006] Compared with existing technologies, the beneficial effects of this technical solution are as follows:

[0007] This fixture is a modification of the original manual valve disc. By adding a valve stem that can connect with the drive device, the disc valve can be electrically operated by the drive device, avoiding manual rotation of the manual valve disc. It can meet the high torque requirements during rotation and is suitable for fluid on / off control in various oil, gas, and water pipelines. It solves the problems of heavy operation, low efficiency, and high torque requirements caused by the complete reliance on manual rotation for opening and closing disc valves in the background technology. It has the beneficial effects of simple installation and operation, saving time and effort, and greatly improving operating efficiency.

[0018] Further preferably, a scale line is provided next to the connection hole.

[0019] Its beneficial effects are: by setting scale lines, the installation position of the connector in each connection hole can be precisely controlled, so that the distance between all connectors and the center of the fixing plate is the same, ensuring the coaxiality of the fixing plate and the valve stem.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] Example 1: As Figures 1 to 2The illustrated fixture for converting a manual disc valve to an electric valve includes a manual valve disc 1 (i.e., a handwheel) and a valve stem 2 passing through the manual valve disc 1. One end of the valve stem 2 extends into the pipeline, transmitting motion to the valve disc. The valve disc moves away from or contacts the valve seat, thus opening and closing the valve. The valve stem 2 controls the opening and closing of the disc valve through its own rotation, thereby allowing or blocking the flow in the pipeline. The other end of the valve stem 2 connects to the output end of a drive device when the pipeline's flow needs adjustment. The drive device rotates the valve stem 2. The manual valve disc 1 is fixedly connected to the valve stem 2 by fasteners, which securely connect the valve stem 2 and the manual valve disc 1, allowing both to rotate synchronously under the action of the drive device. This fixture is a modification of the original manual valve disc 1. By adding a valve stem 2 that can be connected to the drive device, the disc valve can be electrically operated by the drive device, avoiding the need for manual rotation of the manual valve disc 1. It can meet the high torque requirements during rotation and is suitable for fluid on / off control in various oil, gas and water pipelines. It has the beneficial effects of easy installation and operation, saving time and effort, and greatly improving operating efficiency.

[0032] Example 2: Based on Example 1, the valve stem 2 is optimized. The valve stem 2 passes through the center hole of the hub 11 of the manual valve disc 1. The valve stem 2 and the hub 11 of the manual valve disc 1 are coaxially connected by a threaded connection. The two are concentrically aligned. This coaxial arrangement can ensure that the driving force of the drive device can be transmitted to the disc valve in a pure axial direction along the axis of the valve stem 2 (without radial component force), avoiding additional bending moment caused by eccentricity and ensuring the efficient and reliable operation of the disc valve.

[0033] Preferably, an electric wrench is used as the driving device, and a hexagonal bolt is used as the valve stem 2. The driving interface of the electric wrench is connected to the head 21 of the valve stem 2 to improve torque conversion efficiency (torque conversion efficiency ≥95%). This also makes it easy for operators to use. Thus, operating the disc valve with an electric wrench allows for easy opening and closing of the disc valve. Replacing manual rotation with an electric wrench significantly improves work efficiency and reduces labor costs. Specifically, the head 21 of the valve stem 2 is located near the electric wrench, while the tail 22 is located away from the electric wrench. The driving interface of the electric wrench is a hexagonal socket, which is stably connected to the head 21 of the hexagonal bolt, driving the hexagonal bolt to rotate stably.

[0034] Example 3: Based on Example 1, the fasteners are optimized. The fasteners are sleeved and fixed on the valve stem 2 and are respectively arranged on both sides of the manual valve disc 1, that is, on both sides of the plane where the connecting rod 12 of the manual valve disc 1 is located. The connecting rod 12 is used to connect the hub 11 in the middle of the manual valve disc 1 and the rim 13 on the side. The manual valve disc 1 is clamped between the fasteners on both sides, which can improve the connection stability between the manual valve disc 1 and the valve stem 2.

[0035] Specifically, the fasteners include a fixing plate 31 arranged on one side of the manual valve disc 1 and a fixing component 32 arranged on the other side of the manual valve disc 1. The fixing plate 31 and the fixing component 32 are fixedly connected by a connector 4, and the manual valve disc 1 is sandwiched between them, with all three coaxially connected. Thus, the fixing plate 31 and the fixing component 32 secure the manual valve disc 1 through the connector 4, ensuring a stable connection between it and the valve stem 2. The coaxial connection of the fixing plate 31, the fixing component 32, and the manual valve disc 1 ensures efficient and reliable operation of the manual valve disc 1. In addition, the connector 4 passes between adjacent connecting rods 12 of the manual valve disc 1, that is, the connection point of the fixing plate 31 and the fixing component 32 is located between adjacent connecting rods 12 of the manual valve disc 1. This arrangement can restrict the connection position of the manual valve disc 1 and the valve stem 2 to a certain extent and improve the ease of installation.

[0036] Preferably, the connector 4 passes through the connecting hole 311 of the fixing plate 31. The connecting hole 311 has a slotted structure and extends towards the center of the fixing plate 31, that is, the connecting hole 311 is arranged radially along the fixing plate 31. Different specifications and models of disc valves have different outer diameters of the hub 11 in the middle. By setting the connecting hole 311 arranged radially, the position of the connector 4 in the connecting hole 311 can be adjusted when installing this tooling, so as to adapt to different specifications and models of disc valves and improve the applicability of this modified tooling. The length of the connecting hole 311 is 50mm, which can provide a radial adjustment range of ±25mm.

[0037] Further preferably, a scale line is provided next to the connection hole 311, that is, a scale line is engraved on the fixing plate 31 on one side of the connection hole 311. The scale line is arranged along the length direction of the connection hole 311. By setting the scale line, the installation position of the connector 4 in each connection hole 311 can be precisely controlled so that the distance between all connectors 4 and the center of the fixing plate 31 is the same, ensuring the coaxiality of the fixing plate 31 and the valve stem 2.

[0038] Example 4: Based on the above examples, the fixing component 32 is preferably designed. The fixing component 32 includes a plurality of clamping pads 321 connected end to end in sequence. The tail 22 of the valve stem 2 passes through the center of the fixing component 32 and enters the pipeline. The valve stem 2 can pass through the fixing component 32 normally and enter the pipeline.

[0039] Specifically, each end of the clamping gasket 321 has a fixing hole 322, which extends along the length of the clamping gasket 321. The ends of adjacent clamping gaskets 321 are stacked together to form a ring structure. The connector 4 passes through the overlapping fixing holes 322 to fix the adjacent clamping gaskets 321. The valve stem 2 passes through the channel formed by the clamping gaskets 321. After the connector 4 passes through the position determined by the connection hole 311 of the fixing plate 31, it passes vertically through the overlapping fixing holes 322. By stacking and fixing the multi-segment clamping gaskets 321 together, a channel for the valve stem 2 to pass through can be left, which is convenient for assembly and installation. The stacking position of the clamping gaskets 321 can be adaptively adjusted according to the position of the connector 4 in the connection hole 311 of the fixing plate 31 to meet the fastening requirements of different specifications and models of disc valves.

[0040] Preferably, the connecting member 4 is a screw rod, which passes through the fixing plate 31 and the fixing component 32. Nuts 41 are connected to both ends of the screw rod. During installation, rotating the nuts 41 clamps the fixing plate 31, clamping washers 321, and manual valve disc 1 between the nuts 41. The fixing plate 31 is an equilateral triangle, with connecting holes 311 located at the same positions on the three corners of the triangle. Three clamping washers 321 are provided, forming an equilateral triangular ring structure. This structure effectively secures the manual valve disc 1 and valve stem 2 while minimizing material usage and overall load, allowing the electric wrench to rotate the valve stem 2 more smoothly. Both the fixing plate 31 and the clamping washers 321 are made of cast iron, offering advantages such as low cost, simple structure, and durability.

[0041] During installation, first align the valve stem 2, manual valve disc 1, fixing plate 31, and fixing assembly 32 concentrically. Then, adjust the installation position of the fasteners according to the different models of manual valve disc 1. Finally, secure all components firmly with nuts 41 to complete the installation of this fixture. The installation process is simple, easy to implement, and reliable. After installation, use an electric wrench to rotate the head 21 of the valve stem 2 forward or reverse to open and close the disc valve, thus controlling the flow of the pipeline.

[0042] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the technical solution of this application, and these all fall within the scope of protection of this application.
