[0002] The guide rail type stop valve is a valve that guides the linear motion of the valve disc through guide rails, mainly used for controlling the flow and flow regulation of fluid. Its core feature is that it saves labor when opening and closing, has good sealing performance, and is suitable for bidirectional flow media. However, the guide rail type stop valve in the prior art has the following defects when in use: 1. The existing guide rail type stop valve relies only on a single guide rail for limiting sliding, which causes the valve body to easily deviate in position during operation, resulting in insufficient sliding stability and affecting the sealing performance and service life of the valve; 2.

[0041] Installation and Connection: By connecting the valve body 1 to the pipeline through the mounting flange 3 and mounting hole 4, the valve body 1 is integrated with the fluid system.

[0042] The battery box 5 has a built-in battery 32, which powers the electric push rod 9, the motor 31 and the electric cylinder 10, and controls the switch to achieve automated operation.

[0043] Valve disc sliding control: The electric push rod 9 drives the moving plate 27 to rise and fall between the guide rails 26 via a synchronizer, thereby causing the limit plate 22 and the valve disc tube 20 to slide precisely.

[0044] The multi-rail structure automatically compensates for gaps, ensuring that the valve disc tube 20 fits tightly with the main channel groove 33, thus improving the sealing effect.

[0045] Flow regulation and diversion: Rotating the gripping rod 7 causes the threaded valve stem 13 to rotate, which in turn drives the valve column 29 to rise and the vane 30 to rotate, thus regulating the flow rate.

[0046] Motor 31 drives valve spool 29 to rotate, optimizing the fluid path and reducing pressure concentration.

[0047] Diversion and Assistance: The electric cylinder 10 pushes the push column 19 to reciprocate within the flow channel 34, diverting the fluid to the diversion pipe 15 and reducing the pressure peak.

[0048] The auxiliary propulsion device improves the uniformity of flow and enhances the overall flow performance. Beneficial effects

[0049] Sliding stability: The multi-rail collaborative limiting structure reduces vibration and offset, improving sealing reliability by more than 30%.

[0050] Flow rate adjustment accuracy: The multi-level flow rate adjustment module can dynamically adjust the flow rate within the range of 0-100% to meet diverse needs.

[0051] Flow guiding efficiency: The rotating guide vanes and the flow splitting channel work together to improve flow uniformity by 25% and increase flow splitting efficiency by 20%.

[0052] Ease of installation: Modular design simplifies maintenance, adapts to different valve body sizes, and reduces installation time by 40%.
