Precision pressure testing of the Valve Pressure Test Machine.

To meet the requirements of standardized pressure testing, factory quality inspection and working condition simulation tests for all types of industrial valves, the Valve Pressure Test Machine integrates mature hydraulic drive technology, intelligent measurement and control system, and modular adaptability structure. It is specially designed for the strength, sealing performance and pressure-bearing stability testing of valve housings. It can be adapted to the pressure testing operations of various specifications and types of industrial valves, solving the industry problems such as large adaptability limitations of traditional pressure testing equipment, unstable pressure control and insufficient data accuracy. It provides standardized and intelligent pressure testing solutions for the valve manufacturing, engineering support, equipment operation and maintenance, and quality inspection and testing fields.

This equipment has the universal adaptability for all types of valves, covering various connection forms such as flange type, threaded type, and welded type of industrial valves. It encompasses mainstream categories such as gate valves, ball valves, globe valves, butterfly valves, check valves, and regulating valves, and supports the detection of valves with a large range of specifications from DN15 to DN1200mm. It can meet the pressure testing requirements for all low-pressure, medium-pressure, and high-pressure conditions, and the maximum test pressure can adapt to the detection standards of various industrial high-pressure valves. The equipment adopts an adjustable fixture positioning structure, which can quickly and precisely adjust the clamping position according to the size, weight, and structural form of the valve, without the need for frequent replacement of the fixture, significantly improving the efficiency of type change detection. It is suitable for batch production inspection and single-piece customized pressure testing scenarios.

In terms of core pressure testing performance, the equipment is equipped with a closed-loop hydraulic pressure control system, which enables precise pressure increase, stable pressure regulation, and intelligent control throughout the entire pressure release process. This effectively prevents sudden pressure increases or decreases, as well as excessive pressure fluctuations, thereby avoiding damage to the valve body and inaccurate detection data. The equipment supports various pressure testing modes such as water pressure, air pressure, and air tightness tests. It can fully complete a series of quality inspection projects including shell pressure resistance testing, forward/reverse sealing testing, micro-leakage detection, and pressure stability testing. It strictly complies with mainstream valve testing standards such as GB, API, and ANSI. The test results are accurate and compliant, and can serve as the core basis for valve factory qualification and engineering acceptance.

The intelligent and digital configuration significantly enhances the convenience and standardization of the detection process. The entire machine is equipped with a high-definition touch control PLC intelligent operating system. The operation interface is simple and intuitive, and it supports custom settings for core parameters such as test pressure, holding pressure duration, and pressure relief threshold. The equipment is equipped with a high-precision pressure sensor acquisition module, which can monitor the pressure changes throughout the testing process in real time, automatically record the test data, generate pressure curves, and generate a standardized test report after the completion of the test. The data can be stored, traced, and printed throughout the process, completely replacing the inefficient mode of traditional manual reading and manual recording, effectively avoiding human errors and ensuring the standardization and normalization of the quality inspection process.

The equipment combines the dual characteristics of efficient operation and safety protection. It is equipped with multiple intelligent safety protection mechanisms, featuring automatic pressure relief in case of overpressure, real-time abnormal pressure alarm, emergency shutdown, and leakage monitoring protection. These functions comprehensively eliminate potential safety hazards during the pressure test process, ensuring the safe operation of the equipment and the safety of the operators. The entire machine body is formed by thickened steel structure welding, which is highly rigid, stable, and less prone to deformation. The core hydraulic, electrical, and sealing components all use high-quality precision parts, which are resistant to fatigue, wear, and corrosion. It can be adapted to frequent and high-intensity continuous pressure tests in factories for a long time, with low equipment failure rate and simple and convenient daily maintenance, effectively reducing the later operation and maintenance investment of the enterprise.

With its comprehensive advantages including wide versatility, high pressure accuracy, high intelligence level, and stable and safe operation, the Valve Pressure Test Machine can meet the diverse needs of various scenarios such as factory inspection for valve manufacturers, on-site acceptance for engineering projects, annual inspection for special equipment, and re-inspection for valve repairs. It is the core equipment for industrial valve quality control, improving product qualification rates, and standardizing quality inspection processes.
