Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve technology, and in particular to the safety seat structure of hydraulic valves. Background Technology

[0002] A flow control hydraulic valve, also known simply as a flow valve, is an important component of a hydraulic system. It is a valve that changes the flow rate through its orifice by altering the flow area under a given pressure differential. It is used to control the flow rate in a hydraulic system, thereby adjusting the speed of the actuator.

[0003] Hydraulic valve seats are fundamental components of hydraulic systems, primarily used for mounting and securing hydraulic valves to ensure their stable operation. They play a crucial role in sealing and fluid control, essential for the normal operation of the hydraulic system. Hydraulic valve seats not only install and secure hydraulic valves to ensure stable operation but also fulfill critical sealing and fluid control functions. Hydraulic valve seats are typically designed with a mechanism to regulate oil flow. This mechanism adjusts the spring force by rotating bolts, thereby controlling the oil flow path. The end of the spring abuts against a control ball via a connecting rod; the control ball compresses the spring under oil pressure, opening the oil passage. However, the harsh environment in mines and the frequent movement of equipment can cause bolts on hydraulic valve seats to loosen or shift, affecting the regulation and sealing performance of the oil passage. Utility Model Content

[0004] The purpose of this invention is to solve the problem mentioned in the background art: the harsh environment in mines and the frequent movement of equipment can cause bolts on hydraulic valve seats to loosen or shift, thereby affecting the regulation and sealing performance of the oil circuit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The safety seat structure of the hydraulic valve includes a valve seat, an adjusting bolt assembly, and a locking gear plate. An adjusting sleeve is threadedly connected to one side of the valve seat, and an adjusting spring is installed inside the adjusting sleeve. The adjusting bolt assembly includes a bolt body, one end of which is threadedly connected to the outer end of the adjusting sleeve, and a locking gear is fixed to the other end of the bolt body. The locking gear plate is vertically and flexibly mounted on the adjusting sleeve, and the locking gear plate meshes with the locking gear.

[0007] Preferably, a fixing plate is fixed to the outer end of the adjusting sleeve, and a sliding plate is slidably connected to the fixing plate. A lifting rod for driving the locking tooth plate to rise and fall is provided on the sliding plate.

[0008] Preferably, a ring is fixed on the bolt body, the diameter of the ring is larger than the diameter of the bolt body, and a synchronization plate is provided on both sides of the ring body, the upper ends of the two synchronization plates are fixedly connected to the slide plate.

[0009] Preferably, one of the synchronization plates has a groove, and a slider is fixedly connected to one side of the locking tooth plate.

[0010] Preferably, a lifting spring is fitted onto the lifting rod, and the two ends of the lifting spring are respectively connected to the lifting rod and the sliding plate.

[0011] Preferably, the upper end of the lifting rod passes through the sliding plate, and a circular block is fixed to the upper end of the lifting rod, with a flat surface formed on the circular block.

[0012] Preferably, the lifting rod is rotatably connected to the locking tooth plate, a support bar is fixed on the lifting rod, and the slide plate has an insertion hole for inserting the support bar.

[0013] Preferably, push block one and push block two are respectively provided on both sides of the adjusting spring, one end of the bolt body abuts against push block one, and push block two is provided with a groove, in which a control ball is provided.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The engagement of the locking tooth plate and the locking gear keeps the bolt body stable, preventing loosening and displacement. This ensures precise adjustment and sealing performance of the oil circuit, thereby guaranteeing the stable operation of the hydraulic system. The stability of the hydraulic valve seat can reduce the risk of safety accidents caused by system failures and protect the safety of personnel and equipment.

[0016] Ensuring the stability of hydraulic valve seats avoids frequent downtime for maintenance and repairs caused by loose or displaced bolts. This helps reduce downtime and improve production efficiency.

[0017] When the teeth on the locking gear plate correspond to the teeth of the locking gear through the fault-tolerant groove, the locking gear moves on the lifting rod to make the locking gear plate stably mesh with the locking gear. Attached Figure Description

[0031] Please see Figure 1 - Figure 7 The safety seat structure of the hydraulic valve includes a valve seat 1, an adjusting bolt 2, and a locking toothed plate 3. An adjusting sleeve 11 is threaded onto one side of the valve seat 1. The adjusting sleeve 11 has an inner cavity, and an adjusting spring 12 is installed inside the adjusting sleeve 11. The adjusting spring 12 is located in the inner cavity, and push blocks 13 and 14 are respectively provided on both sides of the adjusting spring 12. The adjusting bolt 2 includes a bolt body 21, one end of which abuts against push block 13. Push block 14 has a groove, and a control ball 15 is installed in the groove. The two ends of the adjusting spring 12 are connected to push blocks 13 and 14 respectively. Push block 13 is adapted to the inner cavity of the adjusting sleeve 11. One end of the bolt body 21 is threaded onto the outer end of the adjusting sleeve 11, and a locking gear 22 is fixed to the other end of the bolt body 21. A slot is formed on the outer end face of the bolt body 21 to facilitate rotation of the bolt body 21 using a tool. The locking tooth plate 3 is mounted on the adjusting sleeve 11 in a height-adjustable manner. The locking tooth plate 3 meshes with the locking gear 22 to prevent the bolt body 21 from loosening or shifting.

[0032] A fixing plate 23 is fixed to the outer end of the adjusting sleeve 11. A sliding plate 24 is slidably connected to the fixing plate 23. A lifting rod 25 is provided on the sliding plate 24 to drive the locking tooth plate 3 to rise and fall. The lifting rod 25 is set vertically. When the bolt body 21 needs to be rotated, the lifting rod 25 raises the locking tooth plate 3.

[0033] A ring 211 is fixed to the bolt body 21. The diameter of the ring 211 is larger than that of the bolt body 21. Synchronizing plates 26 are provided on both sides of the ring 211. The upper ends of both synchronizing plates 26 are fixedly connected to the sliding plate 24. When the bolt body 21 moves, the sliding plate 24 moves via the synchronizing plates 26. The sliding plate 24 moves the locking tooth plate 3 via the lifting rod 25, ensuring that the locking tooth plate 3 is always directly above the locking gear 22. One of the synchronizing plates 26 has a groove. A slider 31 is fixedly connected to one side of the locking tooth plate 3. The slider 31 cooperates with the groove to prevent the locking tooth plate 3 from rotating.

[0034] A lifting spring 27 is fitted onto the lifting rod 25. A tolerance groove 32 is provided on the locking tooth plate 3, and a receiving groove is provided on the sliding plate 24. The lower end of the lifting rod 25 is inserted into the tolerance groove 32. The two ends of the lifting spring 27 are connected to the lifting rod 25 and the sliding plate 24 respectively. A limit ring 251 is fixed to the lower end of the lifting rod 25. A tolerance strip 33 is fixed inside the tolerance groove 32, located above the limit ring 251. When the teeth on the locking tooth plate 3 correspond to the teeth of the locking gear 22, the locking gear 22 moves on the lifting rod 25, allowing the locking tooth plate 3 to stably mesh with the locking gear 22. The lifting spring 27 ensures stable meshing between the locking tooth plate 3 and the locking gear 22. The upper end of the lifting rod 25 passes through the sliding plate 24. A circular block 252 is fixed to the upper end of the lifting rod 25. A flat surface is provided on the circular block 252, which facilitates pulling the lifting rod 25 upwards. The lifting rod 25 is rotatably connected to the locking tooth plate 3. A support bar 28 is fixed on the lifting rod. The slide plate 24 has an insertion hole for the support bar 28. After the support bar 28 is rotated, it abuts against the upper surface of the slide plate 24, thereby unlocking the locking gear 22.

[0035] In use, the lifting rod 25 is raised by pulling the round block 252. The lifting rod 25 raises the locking tooth plate 3 and the support bar 28 until the locking tooth plate 3 is completely separated from the locking gear 22, and the locking gear 22 is unlocked. During this process, the lifting spring 27 is compressed. After the locking gear 22 is unlocked, the support bar 28 moves to the upper side of the slide plate 24. Then, the lifting rod 25 is rotated to misalign the support bar 28 with the insertion hole. Then the round block 252 is released. At this time, the lower end of the support bar 28 abuts against the upper surface of the slide plate 24, keeping the locking tooth plate 3 in the unlocked state for easy operation. Personnel free their hands and then rotate bolt body 21. Bolt body 21 moves synchronous plate 26 through ring body 211. Synchronous plate 26 moves slide plate 24, lifting rod 25 and locking tooth plate 3 together. The rotation of bolt body 21 causes push block 13 to move, thereby adjusting the spring of adjusting spring 12. After adjustment, rotate round block 252 so that support bar 28 is aligned with insertion hole. Then release round block 252. Locking tooth plate 3 descends under the action of lifting spring 27. Lifting rod 25 also descends so that locking tooth plate 3 meshes with locking gear 22.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
