[0002] As a control component in the fluid delivery system, valves can effectively control the direction, pressure and flow of the fluid. However, throttle valves are the most common type of valves. The purpose of changing the throttling section length can be achieved through throttle valves. During use, throttle valves can be divided into several major categories such as straight-through type and angle type according to the way of channel. Therefore, throttle valves are widely used in petroleum, natural gas, chemical industry, hydropower and other fields in real life.

[0003] The prior art discloses a barrel-type throttle valve for oil drilling with patent announcement number CN214367780U. The above patent uses an external pulling rod and a rotating bolt to quickly and effectively separate the top plate and the main valve housing, and then can quickly remove the screw rod and the blocking block from the inside of the main valve housing. The related operation is very simple and can be completed quickly by the staff. At the same time, the device is stabilized by reinforcing plates and screw sleeves, which further improves the stability and stability of the device during operation. However, the following deficiencies still exist in actual use: crude oil contains a large amount of hard debris, and the hard debris entering the throttle valve can easily cause damage to the throttle valve, reducing the practicality of the throttle valve. In addition, the hard debris is easy to accumulate and agglomerate, and the accumulated hard debris is difficult to clean and discharge, resulting in difficulty in cleaning the inside of the throttle valve.

[0004] Therefore, a barrel-type throttle valve for oil drilling is needed to solve the problems in the prior art that hard residues in the oil easily damage the throttle valve and the collected hard residues are difficult to discharge after accumulation. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-Figure 4 The utility model provides a barrel type throttle valve for oil drilling, comprising a valve body 1, a valve stem 2 is installed at the center of the top of the valve body 1, a connecting pipe 3 is fixedly connected to the inlet end of the valve body 1, a filtering mechanism 4 is arranged inside the connecting pipe 3, and a cleaning component 5 is arranged inside the connecting pipe 3;

[0023] The filtering mechanism 4 includes a filter plate 41, a mounting plate 42 and a shell 43. The filter plate 41 is arranged on the inner surface of the connecting tube 3. The top surface of the mounting plate 42 is fixedly connected to the top of the inner surface of the connecting tube 3. The bottom surface of the shell 43 is fixedly connected to the bottom of the inner surface of the connecting tube 3. The outer wall of the mounting plate 42 on one side close to the filter plate 41 is rotatably connected with a driving rod 44. The outer wall of the driving rod 44 on one side close to the filter plate 41 is coaxially fixedly connected with an impeller 45. The outer surface of the driving rod 44 is tightly sleeved with a connecting plate 46. The inner wall of the shell 43 is slidably connected with a limiting plate 47. A striking rod 48 is inserted at the center of the side wall of the limiting plate 47. Both sides of the striking rod 48 slide through the outer walls of both sides of the shell 43 and one side of the outer wall is in contact with the bottom of the outer wall of one side of the connecting plate 46. Springs 49 are fixedly connected to the four corners of the outer wall on one side of the limiting plate 47. The side of the spring 49 away from the limiting plate 47 is fixedly connected to the inner wall of one side of the shell 43.

[0024] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the cleaning assembly 5 includes a threaded sleeve 51, the bottom end of the threaded sleeve 51 slides through the top of the outer surface of the connecting pipe 3 and is fixedly connected to an arc plate 52, and three parallel distributed crushing cones 53 are fixedly connected to the bottom surface of the arc plate 52, the internal thread of the threaded sleeve 51 is connected to a threaded rod 54, the top of the outer surface of the threaded rod 54 is rotatably connected to a fixing frame 55, the bottom surface of the fixing frame 55 is fixedly connected to the top of the outer surface of the connecting pipe 3, and the top of the threaded rod 54 is coaxially fixedly connected to a screw column 56.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the bottom of the outer surface of the connecting pipe 3 is fixedly connected to the collecting chamber 6, and the bottom surface of the collecting chamber 6 is provided with a sealing cover 7.

[0026] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that a wing screw 8 for locking the valve stem 2 is provided on one side of the outer surface of the valve body 1, and a connecting flange 9 is fixedly connected to the outflow end of the valve body 1 and the outer wall of one side of the connecting pipe 3.

[0027] Further as Figure 4 As shown, it is worth explaining in detail that the diameter of the filter plate 41 is the same as the inner diameter of the connecting pipe 3 and one side outer wall is fixedly connected to the one side outer wall of the arc plate 52, and the oil passing through the throttle valve is filtered by the filter plate 41. The diameters of the impeller 45 and the connecting plate 46 are both smaller than the inner diameter of the connecting pipe 3, so as to avoid the impeller 45 and the connecting plate 46 interfering with the flow of oil.

[0028] Further as Figure 3 and Figure 4As shown, it is worth explaining in detail that one side of the connecting plate 46 is set to a thick upper and thin lower structure. When the connecting plate 46 rotates, the striking rod 48 is pushed to knock the filter plate 41, so that the filter plate 41 can generate a certain vibration. The outer surface of the arc plate 52 fits the inner surface of the connecting pipe 3 and the length of the arc plate 52 plus the thickness of the filter plate 41 is the same as the inner surface length of the collecting chamber 6. The filter plate 41 and the crushing cone 53 are pushed into the collecting chamber 6 by the threaded sleeve 51, and the hard debris collected in the collecting chamber 6 is crushed by the crushing cone 53, and it is convenient to use a cleaning tool to reach into the collecting chamber 6 to clean the filter plate 41.

[0029] In summary: when the cylindrical throttle valve is in use, the valve body 1 and the connecting pipe 3 are first connected to the external pipeline through the connecting flange 9. After the valve stem 2 is rotated to open the throttle valve, the oil enters the connecting pipe 3, and the filter plate 41 filters and intercepts the hard residue in the oil. The intercepted hard residue enters the collecting chamber 6 for collection. At the same time, the flow of oil drives the impeller 45 to rotate, and the impeller 45 drives the driving rod 44 to rotate, and then drives the connecting plate 46 to rotate. When the thicker part of the upper part of the connecting plate 46 rotates to the bottom, it will push the striking rod 48 to move toward the filter plate 41 to knock the filter plate 41. Under the continuous rotation of the connecting plate 46, the filter plate 41 can produce a certain vibration to prevent the hard residue in the oil from clogging the filter plate 41, and then prevent the hard residue in the oil from entering the valve body 1, effectively avoiding the problem that the hard residue in the oil is easy to cause damage to the throttle valve.

[0030] When it is necessary to clean the debris collected in the collection chamber 6, the oil delivery is temporarily stopped. After opening the sealing cover 7, the screw column 56 is rotated to drive the threaded rod 54 to rotate. Under the action of the thread, the threaded sleeve 51 pushes the arc plate 52 and the filter plate 41 to move downward in the connecting pipe 3. Repeated rotation of the screw column 56 drives the crushing cone 53 to move back and forth in the collection chamber 6, and the hard debris accumulated in the collection chamber 6 is crushed to facilitate the discharge of the debris. When the debris in the collection chamber 6 is emptied, a cleaning tool is used to reach into the collection chamber 6 to clean the filter plate 41. The operation is simple and effectively avoids the problem of the hard debris being difficult to discharge after accumulation.
