Valve Test Stand
1.According to the MT119-85 "Test Specification for Mining Hydraulic Support Valve Types" and "Mining High Pressure Rubber Hose" standards of the Ministry of Coal, emulsion and hydraulic oil are used as working media, and the main performance parameters are safe and meet the testing and tuning of mining hydraulic products and hydraulic components.
2 . The manual directional valve operation eliminates the original shut-off valve, making it easy, reliable, durable, and improving the stability of the entire machine.
3. All test benches use standard hydraulic components for easy maintenance.
4. This machine has fast liquid injection and automatic slow pressure boosting functions, which improve the testing speed and stability.
Valve Test Stand is a new type of test bench developed and designed by visiting and researching various coal mines, integrating the advantages and disadvantages of various test benches at home and abroad. It can be widely used for factory testing of coal mine three-way valves, sealing testing before going down the well, and pressure setting of safety valves. It can also be used for sealing testing and action testing of various hydraulic components of comprehensive mining supports.
Core advantages：
1. Improve detection efficiency and accuracy
The automation process and rapid injection and pressurization functions significantly shorten the testing cycle, while ensuring pressure regulation accuracy through closed-loop control, meeting high standard testing requirements.
2. Reduce manpower and maintenance costs
The automatic loading and unloading and fault diagnosis functions reduce the intensity of manual operations and minimize human errors; Long term preservation of experimental data and archives facilitates equipment management and reduces the cost of repeated testing.
3. Ensure safe production
The high-pressure holding and sealing design ensures the safety and reliability of the testing process, avoiding the risk of leakage and rupture; The fault diagnosis function provides early warning of potential problems and reduces the incidence of accidents.
4. Adapt to diverse needs
Multi interface design and compatibility extension support the detection of different models of three-way valves, and can be integrated into hydraulic systems to meet the needs of multiple scenarios such as coal mines and maintenance units.
About company:
On June 13, 2025, the Safety Standard National Mining Product Safety Mark Center Co., Ltd. (hereinafter referred to as the Safety Standard National Center) issued the CMAC safety certification certificate to Shandong Haozhou Mining Safety Equipment Co., Ltd., marking that Haozhou Mining's pneumatic injection pump for mining has obtained market access and taken product upgrades to a new level.
In recent years, Haozhou Company has relied on its own manufacturing advantages, firmly established the "four business" concept, adhered to the overall idea of "stabilizing the existing business base, focusing on industrial structure upgrading, exploring internal cooperation potential, and deeply seeking green transformation and development", and continuously explored "new paths" for industrial upgrading. Entering the field of mining machinery and equipment manufacturing, we have developed a mining pneumatic booster pump. After strict review by the National Safety Standards Center, it successfully passed the on-site evaluation and obtained the CMAC safety certification certificate.
The mining pneumatic injection pump produced by Haozhou Company is a specialized and efficient equipment that uses compressed air to drive and can quickly provide emulsion in harsh environments such as flammable, explosive, and dusty environments. Mainly suitable for hydraulic support of coal mine underground, advanced support of excavation face, use of pressure column for slope hoisting winch, as well as coal seam water injection and working face cutting. It can also be used as a cleaning pump for coal tunnels and various mechanical equipment.
