Technical Field

[0001] The utility model relates to the technical field of valve bodies, in particular to a valve body for oil extraction with anti-blocking function. Background Technique

[0002] During the process of oil extraction, pipelines are needed to transport oil, and valve bodies are provided on the transportation pipelines to control the flow direction and flow rate of oil.

[0003] Traditional valve bodies do not have the function of crushing sundries. Due to the large amount of sundries in the pipeline, when the valve is closed, the sundries flow into the valve body along with the oil, and the sundries will accumulate at the valve port. Over time, it is easy to block the valve port of the valve body. If the inside of the valve body is blocked, it may affect the service life of the valve body. Summary of the Utility Model

Due to the large amount of sundries in the pipeline, when the valve is closed, the sundries flow into the valve body along with the oil, and the sundries will accumulate at the valve port. Over time, it is easy to block the valve port of the valve body. If the inside of the valve body is blocked, it may affect the service life of the valve body.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A valve body for oil extraction with anti-blocking function, including a main body. A valve is clamped in the middle of the inner side of the main body. An elevating sliding cavity is arranged above the middle of the inner side of the main body.

A fixed column rod is arranged at one end of the valve. A plurality of adjustable arc grooves are formed on the outer surface of the fixed column rod. A hoop plate is fixedly connected to the bottom end of the adjustable arc groove. Four mounting plates are evenly arranged on the outer side of the hoop plate. The top of the mounting plate is fixedly connected to the lower part of the outer side of the screw rod. A plurality of knife plates are evenly arranged on the outer side of the mounting plate. A rocker is fixedly connected to the middle of one end of the knife plate. A connecting plate is arranged at the connection between the rocker and the adjustable arc groove.

[0006] As a further scheme of the utility model: An adjusting screw is arranged above the push rod. One end of the rocker is slidably connected to the adjustable arc groove.

[0007] As a further scheme of the utility model: A collecting cavity is formed in the middle of the inner side of the valve. A filter screen plate is fixedly connected to the bottom of one end of the collecting cavity.

[0012] 1. By setting the screw rod, adjustable arc groove, rocker and knife plate, when the valve slides upward, it will drive the screw rod to rotate. The rotating screw rod will drive a plurality of rockers to slide from the lowest point to the highest point or from the highest point to the lowest point along the adjustable arc groove through the mounting plate fixedly connected to the bottom end. During this process, the rocker will rotate by 90 degrees, thus driving the knife plate fixedly connected to the rocker to rotate by 90 degrees at the gap. The thrust generated by the rotation of the knife plate along the fixed column rod will push the petroleum to flow towards the valve port. At the same time, the horizontal knife plate will cut the larger sundries, which is convenient to crush and push the blockage, and is beneficial to preventing the material from being too large to block the valve port of the valve body.

[0013] 2. By setting the valve, collection cavity, filter screen plate, discharge port, collection box and electric push rod, when the valve is closed, when the flowing petroleum is blocked in the flow path, the petroleum behind it will continue to flow towards the valve due to the inability to quickly stop due to the flow rate. At this time, the sundries contained in the petroleum will flow into the collection cavity under the push of the petroleum flow pressure and stay in the collection cavity. The petroleum entering the collection cavity will flow back into the conveying pipe through the filter screen plate. When the valve slides upward to open, it will bring out the sundries accumulated in the collection cavity from the valve body and move them to the discharge port. The electric push rod will push the push plate to slide into the collection cavity to push the sundries collected in the collection cavity to the discharge port, and enter the collection box through the discharge port, which is convenient to collect the sundries when the valve is closed, and is beneficial to preventing the sundries brought by the liquid flow from blocking the valve port when the valve is closed.

[0021] In this embodiment: By rotating the adjusting screw rod 11, the push-pull rod 6 fixedly connected to the bottom end of the adjusting screw rod 11 is driven to slide upward. The upward-sliding push-pull rod 6 drives the valve 2 fixedly connected to its bottom end to slide into the lifting sliding cavity 7, thereby opening the valve port blocked by the valve 2. During the upward sliding of the valve 2, it will push the spiral hole fixing plate 9 fixedly connected above it to slide upward. During the upward sliding of the spiral hole fixing plate 9, the spiral holes formed on its surface will slide upward along the spiral threads on the outer side of the spiral rod 10, thereby driving the spiral rod 10 to rotate. When the spiral rod 10 rotates, it drives the mounting plate 17 fixedly connected to its bottom end to rotate 360 degrees cyclically around the fixed column rod 13 under the restriction of the hoop plate 12. When the mounting plate 17 rotates, it drives the rocker 15 fixedly connected to one end of the knife plate 16 provided thereon to slide along the adjustable arc groove 14. When the rocker 15 slides from the lower part of the adjustable arc groove 14 to the upper part, it drives the rocker 15 to rotate 90 degrees, thereby driving the knife plate 16 fixedly connected to one end of the rocker 15 to rotate 90 degrees. When one end of the rocker 15 slides from the highest part of the adjustable arc groove 14 to the lowest part, it also drives the rocker 15 to rotate 90 degrees. One rotating rocker 15 drives multiple rockers 15 connected thereto to rotate synchronously through the connecting plate 20, thereby driving multiple knife plates 16 correspondingly connected to the rockers 15 to rotate synchronously. A thrust will be generated between the rotating knife plate and the petroleum, and the thrust will push the petroleum to flow towards the valve port. At the same time, larger impurities in the petroleum will be crushed into small pieces under the action of the knife plate 16, and the small pieces of impurities will flow towards one end of the conveying pipeline along with the petroleum, which is beneficial to preventing the valve port from being blocked by too large impurities.

[0022] Please refer specifically to Figure 1 and Figure 3 , a collection cavity 4 is formed in the middle of the inner side of the valve 2. A filter screen plate 3 is fixedly connected to the bottom of one end of the collection cavity 4. A discharge port 8 is formed in the middle of the rear side of the lifting sliding cavity 7. A collection box 19 is provided at the rear side of the discharge port 8. The collection box 19 is fixedly connected to the middle of the rear side of the main body 1. An electric push rod 18 is provided in the middle of the front side of the main body 1, and a push plate is fixedly connected to the rear side of the electric push rod 18.

[0023] In this embodiment: The reverse-rotating adjusting screw 11 drives the valve 2 fixedly connected to the bottom end of the push-pull rod 6 to slide downward through the push-pull rod 6 fixedly connected below to block the valve port. When the valve 2 is closed, when the flowing petroleum is blocked in the flow path, the petroleum behind it will continue to flow in the direction of the valve 2 because the flow rate cannot quickly come to a standstill. At this time, the impurities contained in the petroleum will flow into the collection chamber 4 under the extrusion of the flow pressure of the petroleum and remain in the collection chamber 4. The petroleum that enters the collection chamber 4 will flow back into the delivery pipe through the filter plate 3. When the valve 2 slides upward to open, the impurities accumulated in the collection chamber 4 will be taken out of the valve body and moved to the discharge port 8. The electric push rod 18 pushes the push plate to slide into the collection chamber 4 to push the impurities collected in the collection chamber 4 to the discharge port 8, and enter the collection box 19 through the discharge port 8, which helps to prevent the impurities accumulated at the valve from blocking the valve port when the valve is closed.
