Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valves, in particular to a butterfly valve opening device. Background Art

[0002] A butterfly valve is a valve used to control the flow of fluids (such as water, gas, oil, etc.). Its main feature is that there is a rotating disc (valve plate) in the valve body, and the flow of the fluid is adjusted by rotating the disc. Butterfly valves are widely used in various industrial fields due to their simple structure, small size, light weight, and quick operation. In the pipeline system, butterfly valves can be used to completely open or close the flow of fluids to control the start and stop of the system.

[0003] In the process of exploitation of resources such as oil, natural gas, and water, there are usually a large number of underground pipeline networks for transporting and controlling fluids. Butterfly valves, as an important component of the pipeline system, are used to control the flow of fluids and ensure the normal operation of the pipeline system. In order to be able to open the valves in the underground enclosed space on the ground and reduce safety risks, the existing technology mostly uses long rods for operation. However, since the underground environment may have problems such as uneven terrain and many obstacles, the long rod may be easily shaken by external forces during operation. If the long rod cannot be fixed, the operator needs more energy and time to adjust the position of the connecting rod, which increases the difficulty and workload of the operation. In addition, the shaking of the connecting rod will cause the butterfly valve to be incomplete or incorrectly opened and closed, which will lead to inaccurate fluid control.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

DETAILED DESCRIPTION

[0020] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0021] According to an embodiment of the utility model, a butterfly valve opening device is provided.

[0022] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 4 As shown, the butterfly valve opening device according to the embodiment of the utility model includes a butterfly valve body 1, a connecting rod 2 is arranged on the top of the butterfly valve body 1, a positioning assembly 3 is arranged on the outer top of the connecting rod 2, and a toggle wheel 4 is arranged on the top of the connecting rod 2.

[0023] With the help of the above scheme, the utility model connects one end of the connecting rod 2 to the sleeve 5 at the bottom, and extends the other end to the ground to connect with the toggle wheel 4, so that the opening and closing of the butterfly valve body 1 located underground can be adjusted on the ground, which greatly simplifies the operation process, reduces the difficulty and time of operation, improves work efficiency, and avoids the risk of operators entering the underground, thereby reducing the possibility of accidents.

[0024] It should be noted that the butterfly valve body 1 is a common valve type, which is widely used in various industrial pipeline systems. The butterfly valve body 1 is usually composed of a valve body, a valve plate, a valve stem, a sealing ring and an actuator. The valve body is the main structural part of the butterfly valve, which is usually made of metal materials (such as cast iron, stainless steel, etc.) and connected to the pipeline. In specific applications, when the actuator drives the valve stem to rotate, the valve plate rotates accordingly, and the valve plate gradually rotates from a closed position (0 degrees) perpendicular to the fluid flow direction to a fully open position (90 degrees) parallel to the fluid flow direction. As the valve plate rotates, the fluid channel gradually opens, the fluid begins to flow, and the flow rate gradually increases. On the contrary, when the fluid needs to be closed, the actuator drives the valve stem to rotate in the opposite direction, and the valve plate gradually rotates from the fully open position (90 degrees) back to the closed position (0 degrees). As the valve plate rotates, the fluid channel gradually closes, the flow rate decreases, until the fluid flow is completely cut off. This is a prior art and will not be elaborated on here.

[0025] In one embodiment, for the above-mentioned connecting rod 2, a sleeve 5 is provided on the outer side of the bottom of the connecting rod 2, and a handwheel handle claw 6 is provided at the bottom end of the sleeve, and a butterfly valve handwheel handle 7 matching with the butterfly valve body 1 is provided at the bottom end of the handwheel handle claw 6. By arranging the sleeve 5 at the bottom of the connecting rod 2, a stable connection between the connecting rod 2 and the butterfly valve body 1 is ensured, and the stability and reliability of the operation are improved. The matching design of the handwheel handle claw 6 and the butterfly valve handwheel handle 7 makes the structure more concise and easy to install and disassemble.

The fixing effect of the gear plate 3 3031 can prevent the butterfly valve body 1 from shaking the connecting rod 2 during operation, thereby improving the stability, operating accuracy, reliability, low maintenance requirements and high safety of the butterfly valve opening device.

The gear plate 3014 and the gear plate 2 3015 can move relative to each other, thereby realizing the clamping and fixing of the gear plate 3 3031 (a plurality of tooth grooves matching the gear plate 1 3014 and the gear plate 2 3015 are provided at the upper and lower ends of the gear plate 3031). When the gear plate 3031 is fixed, the gear 2 3033 is in a fixed state, and through the meshing action of the gear 2 3033 and the gear 1 3032, the shaking of the connecting rod 2 when the butterfly valve body 1 is working can be avoided, thereby improving the stability of the butterfly valve opening device.

[0029] In addition, in actual application, the mounting base 3011 can be installed on the ground, wall, etc. through a fixing device, wherein the fixing device can be bolts and nuts, etc.

[0030] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0031] In actual application, one end of the connecting rod 2 is connected to the sleeve 5 at the bottom, and the other end is extended to the ground and connected to the toggle wheel 4, so that the opening and closing of the butterfly valve body 1 located underground can be adjusted by turning the toggle wheel 4 on the ground. At the same time, the positioning component 3 (the working principle of the positioning component 3 is shown above) can prevent the connecting rod 2 from shaking when the butterfly valve body 1 is working, thereby improving the stability of the butterfly valve opening device.

[0032] To sum up, with the help of the above-mentioned technical scheme of the utility model, the utility model connects one end of the connecting rod 2 with the sleeve 5 at the bottom, and extends the other end to the ground to be connected with the toggle wheel 4, so that the opening and closing of the butterfly valve body 1 located underground can be adjusted on the ground, which greatly simplifies the operation process, reduces the difficulty and time of operation, improves work efficiency, and avoids the risk of operators entering the underground, thereby reducing the possibility of accidents; the utility model sets a positioning component 3, which can fix the gear plate three 3031 under the meshing action between the gear plate one 3014, the gear plate two 3015 and the gear plate three 3031, so that the shaking of the connecting rod 2 of the butterfly valve body 1 during operation can be avoided through the fixing effect of the gear plate three 3031, thereby improving the stability, operation accuracy, reliability, low maintenance requirements and high safety of the butterfly valve opening device.
