The locking ring 11 provides additional fixation, preventing accidental movement of the fixing block 12 during operation, thus ensuring the stability and safety of the entire device. Next to the adjustment knob 9 is the measuring scale 10. The placement of the measuring scale 10 allows the operator to more intuitively observe and adjust the position of the slide valve, improving the accuracy of positioning and the convenience of operation. The measuring scale 10 provides a precise reference, allowing the operator to easily adjust the position of the slide valve, thus improving the efficiency and reliability of the entire system.

[0035] The fixing block 12 is designed to be detachable. This design allows the fixing block 12 to be replaced or adjusted as needed, increasing the flexibility and adaptability of the device, while also facilitating maintenance and care of the device. This design ensures the long-term stability and reliability of the device, while also improving the efficiency of device maintenance.

[0036] The disassembly and replacement time of the fixed block 12 depends on the specific operating environment and the experience of the operator. In an ideal case, if the operator is familiar with the structure and operation process of the device, the fixed block 12 can be disassembled and replaced within a few minutes. However, in actual operation, more time may be needed for disassembly, inspection and reinstallation to ensure the correctness and safety of the device. The main function of the locking ring 11 is to provide additional fixation and stability. By embedding the inner groove 14 provided on the first locator 13, the locking ring 11 ensures the stable position of the fixed block 12 during operation. This design prevents the fixed block 12 from moving accidentally during operation, thereby ensuring the stability and safety of the entire device.

[0037] The lower end of the support seat 5 is provided with a semicircular protrusion 17, which is designed to precisely fit into the corresponding groove on the base 1. This design not only enhances the structural stability of the entire device, but also achieves a tight connection between the support seat 5 and the base 1 through the cooperation of the semicircular protrusion 17 and the base groove. This tight connection helps to reduce the vibration and displacement that may occur during operation of the device, thereby improving the accuracy and reliability of the spool positioning. In addition, the design of the semicircular protrusion 17 also facilitates the installation and disassembly of the support seat 5, making maintenance and repair work more convenient and efficient.

[0038] One side of the support seat 5 is connected with a spool lateral positioning block 4, which functions to push against the side end of the spool 7 to provide additional lateral support and positioning. This design ensures the lateral stability of the spool 7 during operation, preventing the spool 7 from moving or tilting laterally under pressure, thereby ensuring the accurate positioning of the spool 7 and the accuracy of fluid control. The design of the spool lateral positioning block 4 can also be adjusted according to the specific size and shape of the spool 7 to adapt to different types of spools, increasing the versatility and flexibility of the device.

[0039] The connection method of the spool lateral positioning block 4 with the support seat 5 can also be designed according to actual needs, for example, the spool lateral positioning block 4 can be fixed on the support seat 5 by bolts, buckles or other fasteners. This adjustable connection method allows the device to adapt to different working environments and operating conditions, while also facilitating the replacement or adjustment of the spool lateral positioning block 4 as needed.

The base 1 is usually made of a solid material, such as metal or high-strength plastic, to ensure the overall stability and durability of the device. The top of the support seat 5 is designed as an inner concave surface 6 to provide a stable placement platform for the slide valve 7. The inner concave surface 6 is used to place the slide valve 7, and the middle of the slide valve 7 is provided with a slide valve rib 8. The support seat 5 is connected with a fixing block 12 on both sides, and the fixing block 12 is provided with an adjusting knob 9. When the adjusting knob 9 is adjusted, the positioning rod 16 is in contact with the slide valve rib 8, so that the operator can accurately adjust the position of the slide valve 7 to meet different working requirements. The adjusting knob 9 is connected with the positioning rod 16, and the positioning rod 16 abuts against the slide valve rib 8 to realize accurate positioning of the slide valve. This design ensures the stability and accuracy of the slide valve 7 during operation. The positioning rods 16 on both sides abut against the slide valve rib 8 at the same time, enhancing the stability of the slide valve, and the operator can read the measurement scale 10 to determine the middle position of the slide valve rib 8 more accurately. The measurement scale 10 provides a visual reference, allowing the operator to accurately adjust and monitor the position of the slide valve.
