Industry Common Pain Points & Targeted Solutions

3.1 Existing Universal Pain Points in Medium & Small Caliber Flanged Valve Testing

At present, most valve manufacturers are faced with two prominent difficulties in daily finished valve inspection:

1.Low single-station testing efficiency: Traditional single-station valve test bench can only test one valve at a time. Procedures including loading, clamping, pressure holding, unloading are carried out in sequence, with a large amount of idle waiting time. When facing large batch delivery orders, the inspection capacity cannot keep up with production output, resulting in delayed delivery.

2.Unstable clamping force affects detection accuracy: Hydraulic quick-clamping equipment is prone to pressure fluctuation during long-time pressure holding; ordinary manual clamping cannot keep constant tightening force, which easily causes sealing deviation, leading to inconsistent test data and misjudgment of qualified products. Meanwhile, many equipment occupy too much workshop area, which is not conducive to compact production line layout.

3.2 Targeted Optimization Solutions of This Equipment

To solve the above two major pain points restricting factory inspection efficiency and test precision, the Dual Station Screw Driven Vertical Axial Compression Valve Test Bench carries out targeted structural design optimization: Efficiency optimization: Adopt independent dual parallel workstation layout, two stations can work synchronously or separately. While one station is conducting long-time pressure holding test, the other station can finish valve disassembly, assembly and clamping preparation without idle waiting time, and the overall batch detection efficiency is increased by more than 75% compared with single-station equipment. 

Precision & space optimization: Precision screw transmission clamping structure can lock pressure permanently to maintain stable constant pressing force, no pressure attenuation in the whole pressure holding process, effectively guarantee the authenticity of sealing test data; compact vertical integrated layout greatly reduces floor occupation, perfectly adapting to small and medium-sized factories' limited workshop space layout demands.

Seven Core Differentiated Advantages

1.Dual Independent Workstations, Greatly Boost Batch Inspection Efficiency The core advantage of Dual Station Screw Driven Vertical Axial Compression Valve Test Bench: left and right two workstations adopt fully independent clamping and pressure control systems, free to choose synchronous operation or separate operation, can test two different specifications of flanged valves at the same time, thoroughly solve the efficiency bottleneck of traditional single-station serial testing.

2.Precision Screw Clamping, Permanent Constant Compression Force Adopt high-precision trapezoidal screw axial pressing mechanism. After tightening and locking, the clamping force will not decay with time, stable pressing force throughout the whole pressure holding period, will not cause valve sealing surface dislocation or micro-deformation, test results are more stable and repeatable.

3.Dual Media Supported, Meet All Routine Factory Inspection Demands Equipped with complete water charging pipeline and air pressure pipeline system, support water medium for shell strength hydraulic test and air medium for air tightness leakage detection, one machine completes all conventional delivery inspection items of flanged valves.

4.Strictly Compliant with GB/T13927 National Valve Testing Standard All pressure control range, pressure holding time index, sealing detection mode are designed in accordance with GB/T13927 national standard, test data is authoritative and valid, which can be used for factory delivery inspection, third-party quality audit and export commodity inspection certification.

5.Compact Vertical Layout, Save Workshop Floor Space Integrated vertical frame overall molding design, all pressure control components, pressure gauge console and dual test stations are integrated on one base, small occupied area, convenient for workshop arrangement and production line docking, lower requirement for site space.

6.Stable Operation & Low Daily Maintenance Cost Screw mechanical clamping structure has fewer vulnerable parts compared with complex hydraulic servo system, low failure rate, no need for frequent replacement of hydraulic seals and oil maintenance, long service life and low later use cost for enterprises.

7.Wide Caliber Adaptation Range, Strong Versatility Standard model covers DN15 small miniature valves up to DN1000 medium large flanged valves, compatible with gate valves, globe valves, check valves, ball valves and other common flanged industrial valves, flexible switching for multi-variety production inspection.

FAQ & Official Purchase Guidance

Frequently Asked Questions

Q1: Can two stations test valves of different sizes at the same time? 

A1: Two workstations are completely independent in clamping and pressure control, parameters can be adjusted separately, supporting simultaneous testing of valves with different calibers and types.

Q2: Will the screw clamping force drop during long-time pressure holding? 

A2: Adopt trapezoidal self-locking screw structure, after manual locking, the clamping force remains constant all the time without pressure attenuation, which ensures stable sealing detection effect.

Q3: What test media can this equipment use? 

A3: Standard configuration supports water (strength test) and air (air tightness test), two mainstream media for valve factory inspection.
