Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a manual valve that can be equipped with an electric drive component. Background Technology

[0002] Valves are control components in fluid transport systems, and have functions such as shutting off, regulating, guiding, preventing backflow, stabilizing pressure, diverting flow, or overflowing and relieving pressure.

[0003] CN221557760U discloses a water supply and drainage control valve, which includes a valve body and an inlet pipe and an outlet pipe respectively provided on both sides. A valve plate is rotatably provided in the valve body, and a valve stem is provided at the upper end of the valve plate. A handwheel is provided at the upper end of the valve stem extending out of the valve body. The structure of existing manual valves is similar to that of the valve body.

[0004] With the development of automation technology, the manual valves on some old pipelines in the factory can no longer meet the needs of daily production operations. Electric valves, which are more convenient and faster, are being used more and more in the factory pipelines. Therefore, it is necessary to modify the manual valves on the old pipelines in the factory to manual valves that can be equipped with electric drive components. After the electric drive components are installed, the manual valves can be converted into electric valves. However, it is not convenient to connect and fix the shaft and valve stem during the valve modification, which leads to the problem of inconvenience in the modification. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a manual valve that can be equipped with an electric drive component, thus solving the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a manual valve that can be equipped with an electric drive component, including a valve body assembly and an assembly assembly;

[0007] The valve body assembly includes a valve body, a mounting cover is provided on the valve body, a valve stem is provided on the mounting cover, grooves are evenly distributed on the top of the valve stem, and screw holes are provided on the valve stem;

[0008] The assembly includes an upper flange, with arc-shaped plates on both sides of the bottom of the upper flange, and the bottom of the arc-shaped plates are connected to a lower flange. Both the lower flange and the upper flange are connected to a shaft via bearings, and the shaft is sleeved on the valve stem. The inner wall of the shaft is in contact with the groove. The shaft is provided with a bolt 1 connected to a screw hole, and the lower flange is provided with a bolt 2 connected to a mounting cover.

[0009] Preferably, the cross-section of the groove is an isosceles trapezoidal structure with a larger top and a smaller bottom.

[0010] Preferably, guide rods penetrating the lower flange are provided on both sides of the top of the mounting cover.

[0011] Preferably, the outer side of the shaft is uniformly provided with indicator grooves that are opposite to the grooves.

[0012] Preferably, both sides of the bottom of the upper flange are provided with height adjustment devices, and the height adjustment devices are provided with elastic telescopic rods. The elastic telescopic rods are located above the guide rods and are opposite to the guide rods.

[0013] Preferably, the height adjustment device includes a connecting plate disposed on the elastic telescopic rod, a vertical rod slidably connected to the connecting plate is disposed at the bottom of the upper flange, a support bearing is disposed inside the connecting plate, a nut is connected to the inner wall of the support bearing, and the nut extends to the bottom of the connecting plate and the support bearing, the nut is screwed onto the screw rod, and the top of the screw rod is connected to the upper flange.

[0014] This invention provides a manual valve that can be equipped with an electrically driven component. Compared with the prior art, it has the following advantages:

[0015] 1. This manual valve, which can be equipped with an electric drive, facilitates shaft positioning by setting grooves and screw holes on the valve stem. Bolt 1 is installed on the shaft, and then bolt 2 is used to fix the lower flange to the mounting cover. The shaft and valve stem can then be fixed together with bolt 1. The electric drive can be installed on the upper flange to drive the shaft to rotate, thereby rotating the valve stem. Thus, an electric drive can be installed on an existing manual valve, allowing for both manual and electric operation by assembling the electric drive through the assembly components. It is a dual-purpose valve that is convenient and efficient.

[0016] 2. This manual valve, which can be equipped with an electric drive, facilitates the positioning of the lower flange by setting a guide rod; and facilitates observation from the outside by setting an indicator groove opposite to the groove, so as to make the shaft body aligned with the groove on the valve stem, thereby facilitating the connection of the shaft body and the valve stem.

[0017] 3. This manual valve, which can be equipped with an electric drive component, features an elastic telescopic rod. This allows for buffering and deceleration when the lower flange and shaft are lowered, thereby reducing the impact between the shaft and valve stem, as well as the impact between the lower flange and the mounting cover, thus preventing structural loosening of the valve. Furthermore, the height of the elastic telescopic rod can be adjusted using a height adjustment device, allowing it to be moved upwards after the lower flange and shaft are installed, preventing premature failure caused by the elastic telescopic rod being under prolonged compression.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-4 This utility model provides the following two technical solutions:

[0025] First embodiment: A manual valve that can be equipped with an electric actuator, including a valve body assembly and an assembly assembly;

[0026] The valve body assembly includes a valve body 1, a mounting cover 2 is provided on the valve body 1, a valve stem 3 is provided on the mounting cover 2, the valve stem 3 rotates to drive the valve plate to open and close, the top of the valve stem 3 is evenly provided with grooves 4, and the valve stem 3 is provided with screw holes 5.

[0027] The assembly includes an upper flange 6 for mounting an electric drive unit. Both sides of the bottom of the upper flange 6 are provided with arc-shaped plates 8, and the bottom of each arc-shaped plate 8 is connected to the lower flange 7. The purpose of the arc-shaped plates 8 is to avoid interfering with the mounting bolts 10 on the shaft 9. Both the lower flange 7 and the upper flange 6 are connected to the shaft 9 via bearings, and the shaft 9 is fitted onto the valve stem 3. The inner wall of the shaft 9 is in contact with the groove 4. Bolts 10 connected to screw holes 5 are provided on the shaft 9. The groove 4 positions the shaft 9 and is fixed by bolts 10, allowing the electric drive unit to drive the shaft 9 to rotate, thus allowing the valve stem 3 to rotate. Bolts 21 connected to the mounting cover 2 are provided on the lower flange 7.

[0028] The groove 4 has an isosceles trapezoidal cross-section that is larger at the top and smaller at the bottom, which makes it easy to insert the shaft 9 from top to bottom.

[0029] Guide rods 12, which pass through the lower flange 7, are provided on both sides of the top of the mounting cover 2, and can guide the lower flange 7.

[0030] Indicator grooves 13 are evenly provided on the outer side of the shaft 9, which are opposite to the groove 4. When the shaft 9 is fitted onto the valve stem 3, the indicator grooves 13 are used to observe whether it is aligned with the groove 4. After alignment, the shaft 9 is moved downward.

[0031] Height adjustment devices are provided on both sides of the bottom of the upper flange 6, and elastic telescopic rods 14 are provided on the height adjustment devices. The elastic telescopic rods 14 are located above the guide rods 12 and are opposite to the guide rods 12. When the lower flange 7 and the shaft 9 are moved down, the guide rods 12 can block the elastic telescopic rods 14, causing the elastic telescopic rods 14 to compress. This provides resistance to the worker, so as to buffer and decelerate, thereby reducing the collision impact between the shaft 9 and the valve stem 3 and the collision impact between the lower flange 7 and the mounting cover 2, thus preventing the structure of this valve from becoming loose.

[0032] The second embodiment differs from the first embodiment in that the height adjustment device includes a connecting plate 15 mounted on the elastic telescopic rod 14. A vertical rod 16, slidably connected to the connecting plate 15, is located at the bottom of the upper flange 6. A support bearing 17 is installed inside the connecting plate 15, and a nut 18 is connected to the inner wall of the support bearing 17. To facilitate rotation of the nut 18, it extends below the connecting plate 15 and the support bearing 17. The nut 18 is screwed onto a screw rod 19, and the top of the screw rod 19 is connected to the upper flange 6. After the lower flange 7 and shaft 9 are installed, the nut 18 is rotated, causing it to move upwards along the screw rod 19. This, in turn, drives the connecting plate 15, guided by the vertical rod 16, to move the elastic telescopic rod 14 upwards, thus preventing the elastic telescopic rod 14 from prematurely failing due to prolonged compression.

[0033] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0034] In use, the lower flange 7 is guided by the guide rod 12. After the indicator groove 13 is aligned with the groove 4 by rotating the shaft 9, the shaft 9 and the lower flange 7 can be moved down. During the downward movement, the elastic telescopic rod 14 is compressed to slow down the downward movement speed, so as to reduce the impact generated during installation. After the shaft 9 is put on the valve stem 3, the lower flange 7 also contacts the mounting cover 2, and the bolt 10 and bolt 11 can be installed. After installation, the elastic telescopic rod 14 is moved up by the height adjustment device until it is no longer in a compressed state.
