Description

Technical Field

[0001] The utility model relates to the technical field of valve opening regulators, in particular to a remote opening regulator. Background Art

[0002] With the continuous advancement of industrial automation technology, the automated application of remote valve opening adjustment is becoming increasingly widespread. These valves control valve opening through remote signals, enabling automated and intelligent management of production processes. As a key component in fluid control systems, valve automation upgrades are crucial for improving production efficiency, reducing energy consumption, and enabling remote monitoring and control.

[0003] The traditional method for valve automation upgrades involves completely removing existing valves and replacing them with new automated valve groups, which increases the cost of the upgrade. Existing remote control valve connections have numerous limitations, such as poor adaptability, complex installation, and low adjustment accuracy. Due to the wide variety of valve sizes and specifications, traditional installation methods often struggle to accommodate different valve models, requiring multiple component replacements during installation, increasing both installation difficulty and cost. Furthermore, some installed components are prone to loosening or damage over time, impacting the stability and reliability of remote control. Utility Model Content

[0004] The purpose of this utility model is to provide a remote opening regulator, which improves the adaptability, installation convenience and connection stability of the device by optimizing the structural design, thereby meeting the requirements of the industrial automation control field for low-cost valve automation transformation.

[0005] The technical solution of the utility model is as follows:

[0006] The utility model discloses a remote opening regulator, which comprises a locking structure, a transmission structure, a supporting structure and an adjusting actuator. The remote adjustment modification of the valve can be realized by simply removing the valve hand wheel and retaining the original valve structure.

[0007] The locking structure includes an upper clamping seat, and the upper and lower clamping seats are symmetrically arranged on the upper and lower sides of the valve cover and are tightly fitted with the valve cover locking table. The right clamping block and the left clamping block are respectively engaged with the two sides of the upper clamping seat and the lower clamping seat through the clamping groove. The first fastening bolt passes through the corresponding circular holes on the upper clamping seat, the right clamping block and the lower clamping seat in sequence. The second fastening bolt passes through the corresponding circular holes on the upper clamping seat, the left clamping block and the lower clamping seat in sequence. Two right ball studs are screwed into the bolt hole of the right clamping block, and two left ball studs are screwed into the bolt hole of the left clamping block, and the ball heads of the four ball studs are all against the oblique shoulder of the valve cover;

[0008] The transmission structure includes a needle roller bearing. The needle roller bearing, converter, hexagonal nut of the valve handwheel, and coupling are sequentially inserted into the valve stem. The converter is designed with an internal hexagonal hole and locks with the external hexagonal hole of the valve stem sleeve. The outer ring of the converter is a three-leaf half-ring structure with asymmetrical circular grooves on both sides.

[0009] The shallow circular groove on one side of the converter valve can be inserted into a fixed needle bearing, and the deep circular groove can be inserted into the hexagonal nut of the valve handwheel. After the hexagonal nut of the valve handwheel is reinstalled, it enters the deep circular groove and contacts and locks with the bottom surface of the circular groove, locking the valve stem from moving inward. Combined with the original locking function of the valve stem for outward movement, the axial movement of the valve stem is locked;

[0010] One end of the coupling is a three-leaf half ring, which is inserted into the gap of the three-leaf half ring of the converter in a cross-engaging manner to transmit torque, and the other end of the coupling is inserted into the angular stroke rotating sleeve of the actuator;

[0011] The supporting structure includes supporting bolts, which cooperate with the supporting threaded holes of the upper clamping base and the lower clamping base. The assembly path of the supporting bolts is to pass through the elliptical hole of the supporting base and the supporting ring in sequence and then screw into the supporting threaded hole. The four connecting bolts pass through the circular hole of the supporting base and are inserted into the threaded hole of the adjusting actuator and locked.

[0012] The utility model has the following beneficial effects:

[0013] The opening regulator and the valve are tightly connected, and only the valve handwheel needs to be removed, while retaining the original valve main structure to achieve low-cost automation transformation of the valve.

[0014] This device is designed with a card holder block structure with adjustable locking distance and a hexagonal diameter switching converter. This design makes it easy to adapt to valves of various diameters, greatly improving the flexibility and convenience of on-site installation.

[0025] Example

[0026] The present invention is further described in detail below with reference to the accompanying drawings:

[0027] like Figure 1 As shown, a remote opening regulator includes a locking structure, a transmission structure, a support structure and an adjustment actuator 1. It only needs to remove the valve handwheel and retain the original valve structure to realize the remote adjustment modification of the valve;

[0028] like Figure 2-3 As shown, the valve includes a valve cover 17, a valve seat 18, a valve bolt 19, a valve stem 20, and a valve stem sleeve 21. The valve cover 17 is connected to the valve flange 1801 of the valve seat 18 through the valve bolt 19. One side of the valve stem 20 is a gate, which is sealed and inserted into the bottom of the valve seat 18. The other side of the valve stem 20 is a screw, which is sleeved with a valve stem sleeve 21. The inner hole of the valve stem sleeve 21 is processed with a thread, which cooperates with the screw in a threaded connection. The outer side of the valve stem sleeve 21 is designed to have a hexagonal structure that can be embedded in the inner hole of the converter 3. The outer side of the valve stem sleeve 21 is provided with a thread, which is adapted to the hexagonal nut on the valve handwheel.

[0029] like Figure 3 As shown, the locking structure includes an upper card seat 5, and the upper card seat 5 and the lower card seat 10 are symmetrically arranged on the upper and lower sides of the valve cover 17, and are tightly fitted with the valve cover locking table 1702. The right card block 7 and the left card block 11 are respectively engaged with the two sides of the upper card seat 5 and the lower card seat 10 through the card slots. The fastening bolt 1 6 passes through the corresponding circular holes on the upper card seat 5, the right card block 7 and the lower card seat 10 in sequence, and the fastening bolt 2 12 passes through the corresponding circular holes on the upper card seat 5, the left card block 11 and the lower card seat 10 in sequence. Two right ball studs 8 are screwed into the bolt hole of the right card block 7, and two left ball studs 14 are screwed into the bolt hole of the left card block 11, and the ball heads of the four ball studs are all against the valve cover oblique shoulder 1701;

[0030] like Figure 4-5 As shown, the transmission structure includes a needle roller bearing 4. The needle roller bearing 4, converter 3, hexagonal nut of the valve handwheel, and coupling 2 are sequentially inserted into the valve stem 20. The converter 3 is designed with an internal hexagonal hole and locks with the external hexagonal hole of the valve stem sleeve 21. The outer ring of the converter 3 is a three-leaf semi-ring structure, with asymmetrical circular grooves on both sides.

[0031] The shallow circular groove on one side of the valve of the converter 3 can be inserted into the fixed needle bearing 4, and the deep circular groove can be inserted into the hexagonal nut of the valve handwheel. After the hexagonal nut of the valve handwheel is reinstalled, it enters the deep circular groove and contacts and locks with the bottom surface of the circular groove, locking the valve stem 20 from moving inward. Combined with the original locking function of the valve stem 20 for outward movement, the axial movement of the valve stem 20 is locked;

[0032] One end of the coupling 2 is a three-leaf half ring, which is inserted into the gap of the three-leaf half ring of the converter 3 in a cross-fitting manner to transmit torque, and the other end of the coupling 2 is inserted into the angular stroke rotating sleeve of the actuator 1;

[0033] like Figure 1As shown, the support structure includes a support bolt 9, which cooperates with the support threaded holes of the upper clamping base 5 and the lower clamping base 10. The assembly path of the support bolt 9 is to pass through the elliptical hole of the support base 16 and the support ring 13 in sequence and then screw into the support threaded hole. The four connecting bolts 15 pass through the circular hole of the support base 16 and then are inserted into the threaded hole of the adjustment actuator 1 and locked;

[0034] The upper clamping seat 5 and the lower clamping seat 10 are the same parts rotated half a circle, and the right clamping block 7 and the left clamping block 11 are mirrored parts;

[0035] The three-leaf half rings of the converter 3 and the coupling 2 are evenly distributed around the circumference, and the half ring sector angle is 57°-59°;

[0036] The inner hole of the converter 3 is a hexagonal hole, and the distance between opposite sides of the hexagonal hole is 22mm-50mm.

[0037] How it works:

[0038] The locking components of the device play a crucial role in operation. Using a wrench to rotate the two fastening bolts, the upper and lower retaining plates 5 and 10 are locked to the valve cover locking surface 1702. The left and right retaining blocks 11 and 7 engage with the slots in the upper and lower retaining plates 5 and 10, while the ball stud presses against the valve cover shoulder 1701, ensuring the device securely holds the valve cover.

[0039] After adjusting the spacing, tighten all the bolts to achieve a stable connection between the locking component of the device and the valve. When the regulating actuator 1 is started, its angular stroke rotating sleeve begins to rotate, driving the coupling 2 to transmit the rotational power to the converter 3. The converter 3 is connected to the valve stem sleeve 21 with an internal and external hexagonal structure, so it can drive the valve stem sleeve 21 to rotate. Because the hexagonal nuts of the valve cover 17 and the valve handwheel are clamped and locked from the front and back sides, the axial displacement of the valve stem sleeve 21 is avoided. When the rotational power is transmitted to the valve stem sleeve 21, the thread of the inner hole of the valve stem sleeve 21 cooperates with the screw of the valve stem 20, causing the valve stem 20 to produce axial displacement. The movement of the valve stem 20 drives the gate plate to move in the valve seat 18, thereby realizing the adjustment of the valve opening.

[0040] The adjustable locking distance card holder block structure and the hexagonal socket caliber switching converter 3 can adapt to valves of various calibers, improving the flexibility and convenience of on-site installation.

[0041] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and exemplary embodiments. They can be applied to a variety of fields suitable for the present invention. Further modifications will be readily apparent to those skilled in the art. Therefore, the present invention is not limited to the specific details and illustrations shown and described herein without departing from the general concept defined by the claims and their equivalents.
