Description

Technical Field

[0001] The utility model relates to the field of oil valves, and more specifically, it relates to a combined oil valve. Background Art

[0002] Oil valves are extremely important control components in the oil industry. It has various types, such as ball valves, gate valves, globe valves, etc., which are used to control the flow of oil in pipelines, including functions such as opening, closing, and regulating the flow rate. Oil valves are usually made of strong materials to withstand the high pressure, high temperature, and corrosiveness of oil. Its sealing performance is crucial, which can effectively prevent oil leakage and ensure production safety and environmental protection. The precise operation of oil valves plays a key role in all aspects of oil extraction, transportation, and processing, which can ensure the stable operation and efficiency of the process and is indispensable for the safe production and efficient operation of the oil industry.

[0003] Once the handle of the oil valve is rotated to an appropriate state, such as opening to a specific degree or fully closing, etc., under the current working conditions, the fluid state in the pipeline will remain relatively stable. As long as the external conditions do not change significantly, such as the pressure and flow rate do not fluctuate greatly, the position of the valve can maintain this stable fluid control state and does not need to be adjusted frequently (the handle on the oil valve is in an idle state in most cases). However, in the prior art, the handle is fixed on a relatively long valve stem (the purpose of the long valve stem is to increase the force arm to make it easier for the staff to rotate the handle), which occupies more space when not in use and is also vulnerable to impact, with poor practicability.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a combined oil valve. Summary of the Utility Model

[0005] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a combined oil valve.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A combined oil valve, including a valve body, a valve stem arranged above the valve body, and a handle for rotating the valve stem. The combined oil valve further includes:

[0007] A plug-in component, which is arranged between the handle and the valve stem, and includes a disc fixed at the top of the valve stem and a plug-in block arranged below the handle. A groove for the plug-in block to insert is provided on the disc.

[0008] An elastic sealing component, which is arranged on the outer side wall of the disc and is used to seal the groove on the disc.

[0009] Preferably, the number of the grooves, the insertion blocks and the elastic sealing components is two each, which can make the connection of the insertion structure more stable.

[0010] Preferably, the elastic sealing component includes a connecting plate fixed on the outer side wall of the disc. The top of the connecting plate is fixedly connected with a square shell, which is open in the direction towards the disc. Both sides inside the square shell are fixedly connected with cylindrical rods. An activity plate is also installed inside the square shell, and a circular hole is opened on the activity plate to enable it to pass through the cylindrical rod. A spring is sleeved on the outer side wall of the cylindrical rod, and one end of the spring is connected with the activity plate, and the other end is connected with the inner surface of the square shell. A sealing block is fixedly connected to the surface of the activity plate through a cross bar.

[0011] Preferably, the tops of the sealing block and the insertion block are both in a slope shape that matches each other. When the sealing block is pressed downward, the insertion block will be driven to move towards the position of the square shell to open the groove, without the need for staff to push the sealing block, and a single person can operate it.

[0012] Preferably, a transmission rod is installed between the handle and the insertion block, which can increase the torque of the handle through the transmission rod and make it more labor-saving.

[0013] Preferably, the transmission rod includes an outer rod and an inner rod, and the inner rod slides along the inside of the outer rod. The head of the inner rod is fixed to the handle, and the bottom of the outer rod is fixed to the insertion block. Through holes are opened at both sides of the outer rod near the top. A plurality of screw holes are arranged in a vertical array on both sides of the inner rod to adjust the height of the transmission rod and fix the height with screws.

[0014] Preferably, the inner bottom wall of the groove and the bottom of the insertion block are in a slope shape that matches each other, so that the two can be closely attached to improve the firmness of the connection.

[0015] Preferably, blocking plates are fixedly connected to the heads of the cylindrical rods to prevent the activity plate 54 from sliding off the cylindrical rod 53.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. In the normal state of the present utility model, the handle and the valve rod are in a separated state, and the length of the valve rod is relatively short. When it is necessary to change the state of the petroleum valve, first pull the sealing blocks on both sides to move them apart, opening the grooves on the disc and squeezing the spring at the same time. Then align the insertion block under the handle with the groove and insert it into the groove. In this way, the rotation of the disc can be driven by the handle, and the rotation of the valve rod can be driven by the disc to change the state of the petroleum valve. At this time, release the sealing blocks, and the sealing blocks will reset under the influence of the spring force to tightly press the insertion block, improving the firmness of the connection between the handle and the valve rod. After use, pull out the insertion block from the groove to realize the disassembly of the handle. In this way, through the combined setting method between the handle and the valve rod of the petroleum valve, the two can be separated, avoiding the handle occupying space and being impacted. Moreover, through the elastic sealing component, not only can dust be prevented from entering the groove, but also the connection can be strengthened, with higher practicability, thus solving the problems in the background technology that the handle occupies a relatively large space when not in use and is also easily impacted, with poor practicability.

[0018] 2. The present utility model increases the torque of the handle through the transmission rod, making the rotation of the handle more labor-saving. At the same time, the length of the transmission rod can be adjusted as needed to facilitate the staff to adjust the length of the handle from the valve rod according to the actual situation, thereby preventing the installation of the handle from being affected by the obstruction of surrounding objects.

[0026] As Figures 1-5 shown, the present utility model provides a combined oil valve, including a valve body 1, a valve stem 2 arranged above the valve body 1, and a handle 3 for rotating the valve stem 2. The combined oil valve further includes:

[0027] A plug-in component 4, which is arranged between the handle 3 and the valve stem 2, and includes a disc 41 fixed to the top end of the valve stem 2 and a plug-in block 42 arranged below the handle 3. A groove 43 for inserting the plug-in block 42 is formed on the disc 41;

[0028] An elastic sealing component 5, which is arranged on the outer side wall of the disc 41 and is used for sealing the groove 43 on the disc 41. The elastic sealing component 5 includes a connecting plate 51 fixed to the outer side wall of the disc 41. The top end of the connecting plate 51 is fixedly connected with a square shell 52, which is open in the direction towards the disc 41. Both sides inside the square shell 52 are fixedly connected with cylindrical rods 53. A movable plate 54 is also installed inside the square shell 52, and a round hole 55 through which the cylindrical rods 53 can pass is formed on the movable plate 54 (the heads of the cylindrical rods 53 are fixedly connected with baffle plates 59, and the baffle plates 59 are used to prevent the movable plate 54 from sliding off the cylindrical rods 53). A spring 56 is sleeved on the outer side wall of the cylindrical rod 53, one end of the spring 56 is connected with the movable plate 54, and the other end is connected with the inner surface of the square shell 52. A sealing block 58 is fixedly connected to the surface of the movable plate 54 through a cross bar 57.

[0029] Under normal conditions, the handle 3 and the valve stem 2 (the valve stem 2 is relatively short) are in a separated state. When it is necessary to change the state of the petroleum valve, first pull the sealing blocks 58 on both sides to move them apart to open the groove 43 on the disc 41. The sealing blocks 58 drive the movement of the movable plate 54 through the cross bar 57. The movable plate 54 moves linearly along the cylindrical rod 53, squeezing the spring 56 at the same time. Then, align the insertion block 42 under the handle 3 with the groove 43 and insert it into the groove 43. Then, the handle 3 can drive the rotation of the disc 41, and the disc 41 drives the rotation of the valve stem 2 to change the state of the petroleum valve. At this time, release the sealing blocks 58. Under the influence of the elastic force of the spring 56, the sealing blocks 58 will reset to press the insertion block 42, improving the firmness of the connection between the handle 3 and the valve stem 2. After use, pull out the insertion block 42 from the groove 43 to realize the disassembly of the handle 3. In this way, through the combined setting method between the handle and the valve stem 2 of the petroleum valve, the two can be separated, avoiding the handle 3 occupying space and being impacted. Moreover, through the elastic sealing component 5, dust can be prevented from entering the groove 43 (in the initial state, the sealing block blocks the opening of the groove 43 to prevent dust from entering), and the connection can also be strengthened, with higher practicality.

[0030] Moreover, the top of the sealing block 58 and the bottom of the insertion block 42 are both in a slope shape that matches each other. When the sealing block 58 presses down on the sealing block 58, it will drive the insertion block 42 to move towards the position of the square shell 52 to open the groove 43. That is, when the insertion block 42 contacts the sealing block 58, it will drive the movement of the sealing block 58, ensuring that the insertion block 42 can be smoothly inserted into the groove 43 without the need for the staff to pull it open in advance, with higher convenience. At the same time, the inner bottom wall of the groove 43 and the bottom of the insertion block 42 are also in a slope shape that matches each other, enabling them to fit closely and improving the stability of the connection.

[0031] It should be noted that the number of the groove 43, the insertion block 42, and the elastic sealing component 5 is two. In this way, the two symmetrically arranged insertion blocks 42 are inserted into the symmetric grooves 43 on the disc 41, which can make the connection of the insertion structure more stable. At the same time, two elastic sealing components 5 are provided to seal the two grooves 43.

[0032] As a further improvement, a transmission rod 6 is installed between the handle 3 and the insertion block 42. The transmission rod 6 increases the rotational torque of the handle 3, making the rotation of the handle 3 more labor-saving. At the same time, the length of the transmission rod 6 can be adjusted as needed to facilitate the staff to adjust the length of the handle 3 from the valve stem 2 according to the actual situation, thereby preventing the installation of the handle 3 from being affected by the obstruction of surrounding objects. The following is the specific structure of the transmission rod 6: The transmission rod 6 includes an outer rod 61 and an inner rod 62, and the inner rod 62 slides along the inside of the outer rod 61. The head of the inner rod 62 is fixed to the handle 3, and the bottom of the outer rod 61 is fixed to the insertion block 42. Through holes 63 are provided at both sides of the outer rod 61 near the top, and a plurality of screw holes 64 arranged in a vertical array are provided on both sides of the inner rod 62.

[0033] That is, by pulling the inner rod 62 up and down, the inner rod 62 moves up and down along the outer rod 61 to adjust the overall height of the transmission rod 6. After the height adjustment is completed, a screw passes through the through hole 63 on the outer rod 61 and is then installed clockwise into the screw hole 64 at the corresponding height of the inner rod 62, thereby fixing the length of the transmission rod 6.

[0034] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in any form; any ordinary technician in the industry can smoothly implement the present invention according to the instructions in the drawings and the above description; however, any minor changes, modifications, and equivalent variations made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications, and variations made to the above embodiments based on the essence of the present invention still fall within the protection scope of the technical solution of the present invention.
