Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an intelligent hydraulic butterfly valve. Background Technology

[0002] The intelligent hydraulic butterfly valve is a valve that uses hydraulic drive to open and close the butterfly plate. It integrates modern electronic and hydraulic technologies, enabling remote control and automated operation. The valve body is the main part that bears the pressure of the medium and allows fluid flow. The butterfly plate is installed in the valve body and can rotate around a fixed axis to cut off or allow the flow of the medium. The valve shaft connects the butterfly plate and the drive device to transmit power and make the butterfly plate rotate.

[0003] The existing intelligent hydraulic butterfly valves have handwheels designed to allow operators to manually control the opening and closing of the butterfly valve during hydraulic system failures or maintenance. However, this design has significant drawbacks in certain situations. The handwheel is exposed without any protection and is easily subjected to impacts during construction or daily use. Since the handwheel usually protrudes from the valve body, impacts can damage or deform it. If the handwheel is not secured when not in use, it may accidentally rotate due to external impacts. If the operator is operating the butterfly valve in this situation, it could lead to accidental injury or damage to the valve. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides an intelligent hydraulic butterfly valve. By setting a limiting component, when not in use, the operator can rotate the limiting groove inside the handwheel to the upper end, loosen the pull rod, and the return spring pushes the limiting rod to engage with the limiting groove to form a fixed position. This can effectively prevent the handwheel from rotating accidentally due to external impact, avoiding accidental injury or damage to the butterfly valve that may occur when the operator is operating it.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an intelligent hydraulic butterfly valve, including a butterfly valve body, a butterfly plate disposed inside the butterfly valve body, the butterfly plate being mounted on a valve stem, the top end of the valve stem penetrating through the outer wall of the butterfly valve body to the outer shell, a rotating handwheel being connected inside the outer shell, a limiting component being installed on the outer wall of the outer shell, an installation mechanism being provided on the limiting component, the limiting component being fixed to the outer wall of the outer shell through the installation mechanism, and the limiting component limiting the rotation of the rotating handwheel.

[0006] As a preferred technical solution of this utility model, the limiting component includes a mounting plate mounted on the outer wall of the outer shell via a mounting mechanism, a sliding groove opened in the mounting plate, a slider slidably connected to the sliding groove, a limiting rod connected to the slider and inserted into the mounting plate, a return spring wound around the outer wall of the limiting rod, a pull rod fixed on the outer wall of the top end of the limiting rod, and a limiting groove opened in the inner wall of the rotating handwheel.

[0007] As a preferred technical solution of this utility model, the slide groove is symmetrically provided in two sets in the mounting plate, and the length of the slide groove in each set is greater than the length.

[0008] In a preferred embodiment of this utility model, one end of the reset spring is connected to the outer wall of the slider, and the other end of the reset spring is connected to the inner wall of the mounting plate.

[0009] As a preferred embodiment of this utility model, the bottom end of the limiting rod is inserted into the hole, and the diameter of the limiting rod is set to be equal to the diameter of the hole.

[0010] As a preferred technical solution of this utility model, the installation mechanism includes a slot formed on the inner wall of the mounting plate, a threaded groove formed in the outer shell, a threaded rod inserted into the slot and connected to the threaded groove, and a screw cap provided on the outer wall of the top of the threaded rod.

[0011] In a preferred embodiment of this invention, the slot is connected to the threaded groove, and the threaded rod is engaged with the threaded groove for rotational locking.

[0012] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0013] 1. The outer casing provides a certain degree of protection for the handwheel, reducing the possibility of damage or deformation caused by external impacts during construction or daily use.

[0014] 2. By setting the limit component, when not in use, the operator can rotate the limit groove inside the handwheel to the upper end, loosen the pull rod, and the return spring will push the limit rod to engage with the limit groove to form a fixed position. This can effectively prevent the handwheel from rotating accidentally due to external impact, avoiding possible accidental injury or damage to the butterfly valve when the operator is operating it.

[0015] 3. The design of the installation mechanism makes it easy for operators to remove the mounting plate from the outer casing when the limit component needs to be replaced. This is achieved by simply turning the screwdriver on the cover to rotate the threaded rod upwards and removing it from the slot. This allows for easy disassembly and replacement of the mounting plate. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0023] Example:

[0024] like Figure 1-5 As shown, an intelligent hydraulic butterfly valve includes a butterfly valve body 1, a butterfly plate 2 is provided inside the butterfly valve body 1, the butterfly plate 2 is mounted on a valve stem 3, the top of the valve stem 3 passes through the outer wall of the butterfly valve body 1 to the inner shell 5, a rotating handwheel 4 is connected inside the outer shell 5, a limit component 6 is installed on the outer wall of the outer shell 5, an installation mechanism 7 is provided on the limit component 6, the limit component 6 is fixed to the outer wall of the outer shell 5 through the installation mechanism 7, and the limit component 6 limits the rotation of the rotating handwheel 4;

[0025] The limiting component 6 includes a mounting plate 61 mounted on the outer wall of the housing 5 via a mounting mechanism 7, a slide groove 62 formed in the mounting plate 61, a slider 63 slidably connected to the slide groove 62, a limiting rod 64 connected to the slider 63 and inserted into the mounting plate 61, a return spring 65 wound around the outer wall of the limiting rod 64, a pull rod 66 fixed on the outer wall of the top end of the limiting rod 64, and a limiting groove 67 formed in the inner wall of the rotating handwheel 4;

[0026] When the handwheel 4 is turned, the operator needs to pull the lever 66 upwards, causing the lever 66 to drive the limit lever 64 to slide upwards. The limit lever 64 slides upwards in the groove 62 via the slider 63. During the sliding process, the return spring 65 is compressed and deformed until the limit lever 64 moves to the highest position. Then, the handwheel 4 can be turned to control the butterfly plate 2. When the operator does not use the handwheel 4, the 68 inside the handwheel 4 is rotated to the upper end. For better coordination, six sets of 68 are evenly distributed around the outer wall of the handwheel 4. At this time, the operator only needs to loosen the lever 66. The restoring force generated by the elasticity of the return spring 65 pushes the limit lever 64 to return to its original position. Finally, the limit lever 64 and 68 are engaged to form a fixed position.

[0027] It is worth noting that two sets of slide grooves 62 are symmetrically opened in the mounting plate 61, and the length of each set of slide grooves 62 is greater than the length of 68. This design can ensure that the limit component 6 is supported on both sides of the rotating handwheel 4, increasing the stability and symmetry of the structure and avoiding skewing or damage caused by unilateral force.

[0028] One end of the return spring 65 is connected to the outer wall of the slider 63, and the other end of the return spring 65 is connected to the inner wall of the mounting plate 61. This connection method ensures that the return spring 65 can maintain tension when the limit rod 64 moves and provide restoring force when the limit rod 64 returns to its original position. This design allows the limit component 6 to automatically return to its initial position when not in use, ensuring that the butterfly valve can be correctly locked or unlocked.

[0029] The bottom end of the limit rod 64 is inserted into 68, which ensures that the limit rod 64 is tightly engaged with 68 inside the rotating handwheel 4, preventing loosening or misalignment during operation. The diameter of the limit rod 64 is set to be equal to the diameter of 68.

[0030] The mounting mechanism 7 includes a slot 71 formed on the inner wall of the mounting plate 61, a threaded groove 74 formed in the outer casing 5, a threaded rod 72 inserted into the slot 71 and connected to the threaded groove 74, and a screw cap 73 provided on the outer wall of the top of the threaded rod 72.

[0031] When the staff needs to replace the limit component 6, they only need to use a screwdriver to turn the screw cap 73, so that the screw cap 73 drives the threaded rod 72 to rotate upward in conjunction with the threaded groove 74, thereby removing the threaded rod 72 from the slot 71, releasing the fixation between the mounting plate 61 and the outer shell 5, and completing the disassembly and replacement.

[0032] The slot 71 is connected to the threaded groove 74, allowing the threaded rod 72 to be easily inserted into and pass through the slot 71, and then fixed by the threaded groove 74. The threaded rod 72 rotates and locks in place with the threaded groove 74, so that the limiting component 6 can be quickly and securely installed on the butterfly valve. It also facilitates quick disassembly when replacement is needed. By turning the cover 73, the position of the threaded rod 72 can be easily adjusted, thereby fixing and loosening the limiting component 6.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
