Description

Technical Field

[0001] The utility model relates to the field of petroleum valves, and more specifically, to an adjustable petroleum valve. Background Art

[0002] Oil valves are important equipment used to control fluid flow in the petrochemical industry. They play a vital role in ensuring the safe and efficient operation of the production process. Oil valves are widely used in the petrochemical industry. They can handle different types of media such as liquids, gases, oils and steam. Under extreme pressure and temperature conditions, valves can effectively control the operation of the system and ensure production safety.

[0003] Oil valves usually need to accurately control the flow of fluids, including flow rate, pressure and other parameters. Therefore, the angle of the turning handle must be carefully controlled. By controlling the turning angle of the valve handle, the position of the valve disc can be finely adjusted to achieve accurate control of the fluid flow. However, the turning force of the handle on the oil valve is generally fixed and cannot be adjusted according to different staff. The turning amplitude is often too large.

[0004] Therefore, in order to solve the above technical problems, the present application proposes an adjustable petroleum valve. Utility Model Content

[0026] like Figure 1-5As shown, the utility model provides an adjustable petroleum valve, comprising a valve body 1, a valve stem 2 located in the middle of the valve body 1, and a handle 3 fixed to the head of the valve stem 2, a disc 4 is sleeved on the outer wall of the valve stem 2, and the bottom sides of the disc 4 are fixed to the outer wall of the valve body 1 by support rods 11, and a circular ring groove seat 5 is provided on the top of the disc 4. An elastic adjustment component 6 for driving a movable block 7 to move downward is installed at the bottom of the handle 3 away from the valve stem 2. In the initial state, the movable block 7 is not in contact with the circular ring groove seat 5, and the movable block 7 can be driven to move downward by the elastic adjustment component 6, so that the movable block 7 enters the circular ring groove seat 5, so that when the handle 3 is turned, the movable block 7 will rotate along the circular ring groove seat 5, and then the extrusion force between the movable block 7 and the inner bottom wall of the circular ring groove seat 5 is adjusted by the elastic adjustment component 6. The greater the extrusion force, the greater the resistance to the rotation of the handle 3, so as to adjust the rotation force of the handle 3, thereby adjusting the rotation force according to different staff members to achieve the purpose of accurately controlling the flow of the fluid.

[0027] Moreover, the disc 4 and the annular groove seat 5 thereon are divided into two symmetrical parts, and the two parts are detachably connected to the two support rods 11 respectively. With such a split design, the disc 4 and the annular groove seat 5 can be installed after the other parts are installed, which does not conflict with the installation of the parts in the oil valve (for example, if it is not split, the handle 3 needs to be installed at the back, which does not conform to the installation order during the production of the oil valve). The following is the specific detachable structure:

[0028] The lower open groove seats 12 are welded to the lower parts of the symmetrical parts of the disc 4 and the annular groove seat 5 thereon, and the head of the support rod 11 is welded to the insertion block 13. The top of the insertion block 13 is fixedly connected with a screw rod B14. The top of the lower open groove seat 12 is provided with a through hole B15 for the screw rod B14 to pass through. The outer wall of the screw rod B14 is threadedly connected with a nut B16, that is, the lower open groove seats 5 under the two symmetrical parts of the disc 4 and the annular groove seat 5 thereon are respectively inserted into the insertion block 13. After the insertion is completed, the complete disc 4 and the annular groove seat 5 are just formed. At this time, the nut B16 is installed on the screw rod B14 by rotating the nut B16 clockwise. The nut B16 slowly presses against the top of the lower open groove seat 12 to complete the installation of the disc 4 and the annular groove seat 5.

[0029] As a further improvement, the bottom of the handle 3 is fixed to the arrow plate 9 by a vertical rod B8 near the valve stem 2, and the top of the disk 4 is marked with a scale at a position corresponding to the arrow plate 9. When the handle 3 is rotated, the arrow plate 9 will be driven to rotate through the vertical rod B8, so that the arrow plate 9 points to different scales. According to the scale, the staff can better grasp the rotation angle of the handle 3, which is more conducive to precise control of the fluid flow.

[0030] The elastic adjustment component 6 includes a connecting shell 602 connected to the bottom of the handle 3 through a connecting rod 601, and one side of the connecting shell 602 is open. A guide rail 603 for sliding a slider 604 is fixedly connected to the inner surface of the connecting shell 602, and the number of sliders 604 is two. A horizontal plate A605 is fixedly connected to the surface of the upper slider 604, and a horizontal plate B606 is fixedly connected to the surface of the lower slider 604. A spring 607 is installed between the horizontal plate A605 and the horizontal plate B606. The bottom end of the horizontal plate B606 is fixed to the top of the movable block 7 through a vertical rod A608. A downward pressing component 609 is provided at the side end of the connecting shell 602 for driving the horizontal plate A605 to move downward, that is, the horizontal plate A605 is driven by the downward pressing component 609. When moving downward, the horizontal plate A605 drives the horizontal plate B606 to move downward through the spring 607. During the movement, the slider 604 will slide along the guide rail 603 to maintain the linear movement of the horizontal plates A605 and B606 until the movable block 7 enters the annular groove seat 5. Then, the horizontal plate A605 is moved downward, which will squeeze the spring 607 between the horizontal plates A605 and B606. The further downward, the greater the squeezing degree of the spring 607 (the shorter the length), so that the squeezing force of the spring 607 on the inner bottom wall of the annular groove seat 5 is relatively large, and the resistance to the rotation of the handle 3 is also greater. Similarly, the smaller the distance that the horizontal plate A605 moves downward, the smaller the resistance is, and the rotation force of the handle 3 can be adjusted.

[0031] Furthermore, the pressing component 609 includes a connecting plate 6091 fixed at the upper part of the opening end of the connecting shell 602, a screw A6092 is welded to the bottom end of the connecting plate 6091, an expansion plate 6093 with a through hole A6094 provided inside is welded to the side end of the cross plate A605, the expansion plate 6093 is inserted into the screw A6092 through the through hole A6094, and a nut A6095 is threadedly connected to the outer wall of the screw A6092, that is, when the screw A6092 is rotated clockwise, the nut A6095 moves downward along the screw A6092, and the nut A6095 resists the downward movement of the expansion plate 6093, thereby driving the downward movement of the cross plate A605.

[0032] Among them, a rotating plate 6096 is welded on the outer wall of the nut A6095. By rotating the nut A6095 through the rotating plate 6096, the rotating force arm can be increased, which is more labor-saving.

[0033] Moreover, the bottom end of the connecting rod 601 is fixedly connected with the mounting plate 10, and the mounting plate 10 and the connecting shell 602 are detachably connected by screws, so that the elastic adjustment component 6 can be disassembled, and when a component thereof is damaged, it can be disassembled and replaced.

[0034] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
