Product Introduction: Gate Valve Gate valve is a high-pressure cut-off pipeline fitting widely matched with mud pump manifolds, water supply pipelines, sprinkler truck piping and oilfield circulation systems, used to fully open or completely close the flow channel of drilling fluid, water and other media, and cannot be used for flow regulation. Material & Structure The valve body is integrally forged from high-strength alloy steel, with thick wall to withstand alternating high slurry pressure. Internal core components include gate plate, valve stem, sealing base, handwheel and stuffing box sealing assembly. The metal hard-sealed gate plate fits tightly with the valve seat, featuring strong anti-scouring performance against sand-containing mud. The external stuffing box is equipped with multi-layer sealing rings to prevent medium leakage along the valve stem during switch operation. Standard flange or threaded connection ports support quick installation with mud pump pipelines, welded flanges and pressure gauges. Core Advantages 1. Small flow resistance: Straight-through internal passage with no flow dead zone, low mud deposition risk, ensuring smooth transmission of high-solid drilling fluid. 2. Reliable full sealing: Double-sided hard sealing structure, zero leakage under rated working pressure after complete closing, effectively isolating pipeline pressure for equipment overhaul. 3. Strong wear & corrosion resistance: Internal flow surface anti-rust and wear-resistant treatment, adapts to long-term delivery of abrasive, slightly corrosive drilling mud and cleaning water. 4. Simple operation & easy maintenance: Handwheel manual driving design; disassembleable valve body structure for regular cleaning of sediment and replacement of sealing parts on site. Main Application Scenarios 1. Oil & geotechnical drilling: Installed on mud pump suction and discharge manifolds, used to cut off mud flow during pump maintenance, liner and valve replacement. 2. Municipal sanitation: Fitted on sprinkler truck water pipelines to control water supply for flushing nozzles and water cannons. 3. Construction engineering: Applied to high-pressure water supply pipelines for dust suppression and foundation grouting equipment. Functional Value It realizes independent segmented control of each branch of the circulation pipeline, allows safe pressure relief and offline maintenance of single equipment without stopping the whole system. It avoids medium waste and safety hazards caused by pipeline leakage, and is an indispensable safety control fitting for all pumping fluid delivery systems.
