• Energy-Efficient Pneumatic-Hydraulic Booster CircuitConsumes only 0.75 kW total electrical power while leveraging pneumatic booster technology for fast fluid fill, rapid pressure buildup, and leak-free pressure holding.
• Comprehensive Multi-Mode Inspection ScopeCapable of performing complete safety routines, including shell hydrostatic strength tests, high-pressure liquid seat leakage tests, low-pressure air tightness checks, and stem backseat sealing tests.
• Compact Production Line FootprintDesigned with overall dimensions of 2600 × 700 × 1800 مم, allowing effortless integration into QA testing cells, valve manufacturing assembly lines, or workshop maintenance bays.

Technical Specifications of Valve Pressure Test Bench

Inspection Modes & Testing Capabilities

The bench provides comprehensive multi-mode testing protocols for complete quality assurance:

• Shell Hydrostatic Strength Test: Verifies the pressure-containing capability of valve body castings, forgings, and bonnet joints under 1.5× nominal pressure.
• High-Pressure Liquid Seat Leakage Test: Evaluates internal closure performance between the valve disc and seat ring using pressurized liquid to measure bubble or droplet leakage rates.
• Low-Pressure Gas Tightness Test: Uses low-pressure compressed air (typically 0.6 MPa) to detect micro-porosity and sealing failures under gaseous conditions.
• Backseat Sealing Test: Evaluates the stem-to-bonnet backseat seal when the valve is fully open, ensuring safety under line pressure during stem packing maintenance.
• Pipe Fitting Pressure Checks: Suitable for evaluating structural pressure integrity for pipe segments, elbows, tees, and commercial plumbing fittings.

اختبار سير العمل & التطبيقات المستهدفة

سير عمل الاختبار الموحد:

1. Mount the target valve or pipe fitting onto the clamping unit using the appropriate threaded or flanged adapter plates.
2. Engage the hydraulic clamping system to secure a leak-free seal across the connection faces.
3. Select the desired test mode (Hydrostatic Shell Test or Pneumatic Seat Leak Test) on the central control panel.
4. Initiate fluid fill and pressure buildup via the 0.75 kW pneumatic-hydraulic booster system until reaching the target setting (up to 6.3 MPa).
5. Hold pressure for the standard-specified duration (على سبيل المثال, واجهة برمجة التطبيقات 598 holding time), monitor for pressure drops or visible leakage, and relieve system pressure safely.

Valve Pressure Test Bench FAQ

س1: What types of valves and fittings can be tested on this bench?

أ: It is designed for female-threaded and flanged valves up to DN200 (8″), including gate, globe, check, ball, and HVAC/plumbing valves. It also tests structural pressure integrity for pipe segments, elbows, tees, and standard plumbing fittings.

Q2: How does the system handle both liquid strength and gas tightness tests?

أ: The system incorporates dual-fluid testing circuits. High-pressure liquid (water with rust inhibitor up to 6.3 MPa) is routed for shell strength and seat leakage tests, while a low-pressure compressed air line is selected for micro-leak gas tightness testing.

س3: What makes the pneumatic-hydraulic booster circuit advantageous?

أ: The pneumatic-hydraulic booster design allows the bench to generate high hydraulic pressures up to 6.3 MPa while keeping power consumption extremely low at just 0.75 كيلوواط. It provides smooth pressurization and stable holding cycles without continuous motor strain.
