DN100 Split Water Tank Horizontal Valve Test Bench

This Split Water Tank Horizontal Valve Test Bench is specially designed for shell hydrostatic strength test and seat air tightness submerged bubble inspection of flanged straight-through valves, fully complying with GB/T13927 and API 598 international valve testing standards. It is equipped with independent high-pressure boosting system, multi-group precision pressure gauges and pressure transmitters, plus automatic constant pressure holding control module; users can freely set test pressure and pressure holding duration according to different valve pressure classes. The horizontal clamping structure supports horizontal placement of medium & large-sized valves, eliminating the safety risk of lifting heavy valves for vertical test benches. 

After clamping the valve, operators can push the workpiece into the independent diving water tank, directly observe bubble overflow to judge sealing leakage status, with intuitive and reliable test results, effectively avoiding missed leak detection caused by indirect pressure data judgment. The split water tank can be placed separately beside the main control cabinet, suitable for workshops with limited installation space; the tank body adopts thickened anti-rust steel plate welding, with drainage port for easy daily sewage cleaning. The main control cabinet integrates all pressure regulation, boosting and electrical operation modules, with independent sealed cabinet door to protect hydraulic and electrical components from water vapor corrosion. 

The equipment covers DN15~DN100 standard flanged ball, gate and globe valves, supporting two testing media of water and air. It reserves touch screen digital upgrade interface for automatic pressure curve recording and test report export; we can provide full CE safety transformation and multi-language operation panel for overseas valve factories and energy EPC inspection workshops. If you need split-type visual submerged bubble valve pressure testing equipment for factory delivery inspection and maintenance recheck, contact our technical team to obtain complete parameter sheet and long-term framework quotation within 24 working hours.

Seven Core Differentiated Product Advantages

1.Split Independent Main Machine & Diving Water Tank Layout The landmark structural feature of YFJX-LQ DN100 Split Water Tank Horizontal Valve Test Bench: separate control cabinet and water tank can be arranged flexibly according to workshop layout, the water tank can be moved independently without moving the heavy hydraulic main unit, solving the fixed space limitation of integrated test benches, highly adaptable to small and medium valve workshops.

2.Horizontal Side Clamping for Medium & Large Valve Easy Loading Horizontal axial clamping design requires no vertical hoisting of heavy valves, workers only push the valve horizontally to complete positioning and clamping, reducing labor intensity and falling safety hazards; the adjustable clamping stroke matches various length DN15-DN100 flanged valves, one machine covers full conventional specifications, another core practical advantage of YFJX-LQ DN100 Split Water Tank Horizontal Valve Test Bench.

3.Intuitive Submerged Bubble Visual Leakage Detection Whole valve is fully immersed in clean water tank during air tightness test, leakage point will generate continuous air bubbles, inspectors can directly locate tiny sealing gaps which are hard to identify only through pressure fluctuation data, greatly improving the accuracy of low-pressure air tightness inspection.

4.Dual Medium Independent Boosting & Pressure Holding System Separate hydraulic water boosting pipeline and pneumatic air boosting pipeline, equipped with independent pressure regulation valves and precision pressure monitoring gauges, can carry out shell water strength test and seat air tightness test separately, automatically compensate pressure loss during holding period to maintain stable test pressure.

5.Anti-rust Thickened Detachable Diving Water Tank The split water tank is welded with thickened carbon steel plate with anti-corrosion paint inside and outside, equipped with bottom drain valve for quick cleaning of residual water and metal impurities after daily testing; independent tank design avoids water vapor entering the electrical control cabinet to cause circuit short circuit.

6.Multi-layer Overpressure & Water Vapor Safety Protection Built-in hydraulic overpressure relief valve, gas overpressure cut-off valve and cabinet waterproof sealing structure, triple safety interlock to prevent overpressure valve burst and electrical component damp damage, fully meet EU CE industrial mechanical safety standards for export.

7.Reserved Modular Digital Intelligent Upgrade Port The main control electrical system reserves data communication expansion interface, customers can later retrofit touch screen PLC automatic test cycle, pressure curve storage and electronic inspection report export function, realize full digital traceability of inspection data and seamless docking with factory MES intelligent management system.
