Description

Technical Field

[0001] This utility model relates to the field of hydraulic oscillator technology, specifically a valve for a hydraulic oscillator. Background Technology

[0002] A hydraulic oscillator is a downhole tool that improves the effectiveness of drilling pressure transmission and reduces frictional resistance with the wellbore by generating longitudinal vibrations. The hydraulic oscillator disc valve includes a moving valve seat, a moving valve plate, a fixed valve seat, and a fixed valve plate, with the moving valve seat connected to the rotor.

[0003] In existing hydraulic oscillators, the moving and stationary valve plates in the valves are mostly connected to the moving and stationary valve seats by bolts. However, the bolt fixing method has the drawback of inconvenience in disassembly and assembly, making it difficult to disassemble and replace the moving and stationary valve plates.

[0004] To address the aforementioned problems, this application proposes a valve for a hydraulic oscillator. Utility Model Content

[0005] To address the inconvenience of disassembly and assembly in existing valves for hydraulic oscillators where the moving and fixed valve plates are bolted to the moving and fixed valve seats, the purpose of this invention is to provide a valve for hydraulic oscillators.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a valve for a hydraulic oscillator, including a moving valve seat and a fixed valve seat, wherein a connecting cover and a threaded pipe are fixedly connected to the moving valve seat, and a moving valve plate is detachably provided on the inner side of the moving valve seat. The connecting cover is provided with an array of connecting grooves. A fixed valve plate is detachably provided on the inner side of the fixed valve seat to cooperate with the moving valve plate. The inner sides of the fixed valve seat and the moving valve seat are respectively provided with fixing mechanisms to cooperate with the fixed valve plate and the moving valve plate. Both the moving valve plate and the fixed valve plate are provided with eyelets for cooperation. Both the moving valve plate and the fixed valve plate are provided with stabilizing mechanisms for cooperation.

[0007] The fixing mechanism includes a fixing cylinder, which is fixedly installed on the inner walls of the moving valve seat and the fixed valve seat respectively. A rotating ring is rotatably inserted into the inner side of one end of the fixing cylinder. A torsion spring is fixedly installed at one end of the rotating ring, and the end of the torsion spring is fixedly connected to the inner wall of the fixing cylinder. A rotating rod is fixedly inserted into the rotating ring, and the rotating rod rotates through the fixing cylinder and a chuck is fixedly sleeved at its end. A rotating hole is opened through one end of the fixing cylinder, and the rotating rod is rotatably inserted into the rotating hole. A symmetrically distributed locking block is integrally formed on the chuck. Both the moving valve plate and the fixed valve plate are provided with a fixing hole and a fixing groove for matching use. A locking groove is opened on the inner wall of the fixing hole. The locking block can slide through the locking groove and can slide and fit against the inner wall of the fixing groove.

[0008] Preferably, the stabilizing mechanism includes a stabilizing ring. Symmetrically arranged inner grooves are formed inside both the moving valve plate and the fixed valve plate, and the stabilizing ring is slidably engaged within the inner grooves. A spring is fixedly installed on one side of the stabilizing ring, and the end of the spring is fixedly connected to the inner wall of the inner groove. A stabilizing rod is fixedly inserted into the stabilizing ring, and the stabilizing rod can slide through the moving valve plate and the fixed valve plate respectively and be inserted into the moving valve seat and the fixed valve seat respectively. Both the moving valve plate and the fixed valve plate have sliding holes communicating with the inner grooves, and the stabilizing rod slides through the sliding holes. Both the moving valve seat and the fixed valve seat have symmetrically distributed stabilizing holes, and the stabilizing rod can slide into the stabilizing holes. Both the moving valve seat and the fixed valve seat have push holes communicating with the stabilizing holes, and the push holes cooperate with the stabilizing rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. The use of the fixed mechanism facilitates the convenient rotation and reset of the card block, thereby facilitating the docking, sliding and misalignment of the card block and the card slot, which in turn facilitates the connection and separation of the moving valve plate and the moving valve seat, as well as the connection and separation of the fixed valve plate and the fixed valve seat, and further facilitates the disassembly and assembly of the moving valve plate and the fixed valve plate.

[0011] 2.

[0018] 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.

[0019] Example: Figures 1-4 As shown, this utility model provides a valve for a hydraulic oscillator, including a moving valve seat 1 and a fixed valve seat 2. The moving valve seat 1 is fixedly connected with a connecting cover 3 and a threaded pipe 4 for use, and the moving valve seat 1 is detachably provided with a moving valve plate 5 for use. The moving valve seat 1 is fixedly connected to the rotor through the threaded pipe 4. The connecting cover 3 is provided with an array of connecting grooves 31. The fixed valve seat 2 is detachably provided with a fixed valve plate 6 for use with the moving valve plate 5. The fixed valve seat 2 and the moving valve seat 1 are respectively provided with fixing mechanisms 7 for use with the fixed valve plate 6 and the moving valve plate 5. The moving valve plate 5 and the fixed valve plate 6 are both provided with eye holes for use. The moving valve plate 5 and the fixed valve plate 6 are both provided with stabilizing mechanisms 8 for use.

[0020] The fixing mechanism 7 includes a fixing cylinder 71, which is fixedly installed on the inner walls of the moving valve seat 1 and the fixed valve seat 2 respectively. A rotating ring 72 is rotatably inserted into the inner side of one end of the fixing cylinder 71. A torsion spring 73 is fixedly installed at one end of the rotating ring 72, and the end of the torsion spring 73 is fixedly connected to the inner wall of the fixing cylinder 71. A rotating rod 74 is fixedly inserted into the rotating ring 72, and the rotating rod 74 rotatably passes through the fixing cylinder 71 and a chuck 75 is fixedly sleeved at its end. One end of the fixing cylinder 71 passes through... A rotating hole 77 is provided, and the rotating rod 74 is rotatably inserted into the rotating hole 77. The use of the rotating hole 77 provides a guarantee for the stable rotation of the rotating rod 74. The chuck 75 is integrally formed with symmetrically distributed locking blocks 76. The moving valve plate 5 and the fixed valve plate 6 are both provided with a fixing hole 9 and a fixing groove 10 for matching use. The inner wall of the fixing hole 9 is provided with a locking groove 11. The locking block 76 can slide through the locking groove 11 and can slide and fit against the inner wall of the fixing groove 10.

[0021] By adopting the above technical solution, during use, the two locking blocks 76 on the synchronous knob moving valve seat 1 or fixed valve seat 2 can drive the corresponding chuck 75 to rotate, which in turn drives the corresponding rotating rod 74 to rotate, and further drives the corresponding rotating ring 72 to rotate and twist the corresponding torsion spring 73 until the corresponding locking block 76 is rotated ninety degrees. Then, the ends of the moving valve plate 5 and the fixed valve plate 6 away from the fixed groove 10 are respectively inserted into the moving valve seat 1 and the fixed valve seat 2, and the locking block 76 is locked into the corresponding locking groove 11. After that, the moving valve plate 5 and the fixed valve plate 6 are completely locked into the moving valve seat 1 and the fixed valve seat 2, respectively. At this time, the torsion spring 73 will drive the corresponding locking block 76 to reverse and reset, thereby enabling the locking block 76 to be misaligned with the locking groove 11 and fixing the corresponding moving valve plate 5 or the fixed valve plate 6.

[0022] The stabilizing mechanism 8 includes a stabilizing ring 81. Symmetrically arranged inner grooves 12 are provided inside both the moving valve plate 5 and the fixed valve plate 6. The stabilizing ring 81 is slidably engaged within the inner grooves 12. A spring 82 is fixedly installed on one side of the stabilizing ring 81, and the end of the spring 82 is fixedly connected to the inner wall of the inner groove 12. A stabilizing rod 83 is fixedly inserted into the stabilizing ring 81, and the stabilizing rod 83 can slide through the moving valve plate 5 and the fixed valve plate 6 respectively, and is respectively inserted into the moving valve seat 1 and the fixed valve seat 2. Both the moving valve plate 5 and the fixed valve plate 6 have symmetrically arranged inner grooves 12. The inner groove 12 is connected to the sliding hole 15, and the stabilizing rod 83 slides through the sliding hole 15. The setting of the sliding hole 15 ensures the stable sliding of the stabilizing rod 83. The moving valve seat 1 and the fixed valve seat 2 are both provided with symmetrically distributed stabilizing holes 13, and the stabilizing rod 83 can be slidably inserted into the stabilizing hole 13. The moving valve seat 1 and the fixed valve seat 2 are both provided with push holes 14 that are connected to the stabilizing holes 13, and the push holes 14 are used in conjunction with the stabilizing rod 83. The setting of the push holes 14 provides convenience for the easy pushing of the stabilizing rod 83.

[0023] By adopting the above technical solution, when in use, pushing the two stabilizing rods 83 on the moving valve plate 5 or the fixed valve plate 6 to move in opposite directions can drive the corresponding two stabilizing rings 81 to move in opposite directions and squeeze the corresponding springs 82 until the distance between the two stabilizing rods 83 is minimized. When the moving valve plate 5 and the fixed valve plate 6 are completely inserted into the moving valve seat 1 and the fixed valve seat 2 respectively, the springs 82 will drive the corresponding stabilizing rods 83 to reset and insert them into the corresponding stabilizing holes 13, thereby stabilizing and limiting the corresponding moving valve plate 5 or the fixed valve plate 6.

[0024] Working principle: During use, the two locking blocks 76 on the moving valve seat 1 or the fixed valve seat 2 are rotated synchronously, which drives the corresponding chuck 75 to rotate, which in turn drives the corresponding rotating rod 74 to rotate, which in turn drives the corresponding rotating ring 72 to rotate and twist the corresponding torsion spring 73 until the corresponding locking block 76 is rotated 90 degrees. Then, the two stabilizing rods 83 on the moving valve plate 5 or the fixed valve plate 6 move in opposite directions, which drives the two corresponding stabilizing rings 81 to move in opposite directions and compress the corresponding spring 82 until the distance between the two stabilizing rods 83 is minimized. The ends of valve plate 5 and fixed valve plate 6 away from the fixed groove 10 are respectively inserted into the moving valve seat 1 and the fixed valve seat 2, and the locking block 76 is locked into the corresponding locking groove 11. Then, the moving valve plate 5 and the fixed valve plate 6 are completely locked into the moving valve seat 1 and the fixed valve seat 2, respectively. At this time, the torsion spring 73 will drive the corresponding locking block 76 to reverse and reset, so that the locking block 76 and the locking groove 11 are misaligned and the corresponding moving valve plate 5 or fixed valve plate 6 is fixed. The spring 82 will drive the corresponding stabilizing rod 83 to reset and insert it into the corresponding stabilizing hole 13, thereby stabilizing and limiting the corresponding moving valve plate 5 or fixed valve plate 6.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
