Valve Test Equipment
Valve test equipment can be used for a variety of applications, such as intermediate and final inspections by valve manufacturers, testing of new valves on delivery, and routine or post-maintenance testing of valves in service. These include, for example, pressure testing of valve housings, leakage testing of valve seats, and set pressure testing of safety valves.

Other components can also be pressure tested, such as tanks, motor housings, pump housings, pipe fittings, insulators etc. Special clamping devices may be required to clamp these test pieces.

Structure and working principle
Valve test equipment is composed of hydraulic system, electrical control system, high and low pressure water pump pressure supply device system, oil pressure, water pressure instrument system, control valve system, clamping workbench system and hydraulic medium storage circulating water tank. The test process and results meet relevant regulations and requirements.

The valve test equipment adopts flange end face sealing, holding pressure claw to directly clamp the valve, and the back of the flange is compressed. The clamping mechanism is directly driven by the clamping oil cylinder of the clamping claw. The axial direction of the clamping claw can move forward and backward, which is not limited by the thickness of the flange. The radial movement is composed of oil cylinder and lever to realize the radial synchronous movement of each clamping jaw. The radial clamping jaw can move forward and backward. It is not limited by the diameter of valve flange. There is no external force on the test valve.

The left end of the test bench can move horizontally left and right, and the pressure test is not limited by the structural length of the test valve; The right end can be turned over 90 degrees to facilitate the sealing and air tightness test of the valve.

The high-pressure water pump is powered by the 4-7 bar air pressure system and automatically reverses through the electrical control reversing valve to make the high-pressure water pump work automatically and reciprocally. The water suction check valve and water outlet check valve are interchanged to continuously supply pressure to the tested valve to meet the pressure requirements of the tested valve.

It is applicable to the high-pressure water seal test of 1.1 times the nominal pressure, the high-pressure water shell test of 1.5 times the nominal pressure and the low-pressure air tightness test of 4-7bar for flange valves.

The XX hydraulic manufacturing company in Germany has been rooted in the hydraulic system equipment of the airport for many years. A batch of hydraulic pressure reducing valves purchased by the novice Carla at the beginning of the year were repeatedly complained by the airport, which brought a lot of losses to the company's after-sales service and alerted the boss. In the first half of last year, Carlaâ??s company sold hydraulic power units to Malaysia, which is used to supply emergency fuel to aircraft at the airport. The equipment was reported for repair after running for about a month. The after-sales engineer handled it at Kuala Lumpur Airport and locked the abnormality of the hydraulic pressure reducing valves according to the fault code. Finally, it was found that the sealing ring of the hydraulic pressure reducing valves was corroded, affecting the operation of the equipment.

The engineer asked Carla to mail the new sealing ring to the site within 2 weeks. The manufacturer of the original hydraulic pressure reducing valves learned that the sealing ring was seriously corroded and was willing to replace with fluororubber sealing rings, which have the best corrosion resistance, for free. The manufacturer also reminded Carla that when she placed the order, the medium used in the hydraulic pressure reducing valves was not specified, so the conventional nitrile rubber sealing rings were equipped. Considering that Carla is a novice, he is willing to offer replacements for free.

Carla thought that the abnormal hydraulic pressure reducing valves were solved in this way. Unexpectedly, the same problem occurred only two months after the replacement. The customer was angry and said that if the second after-sales service still couldn't solved the problem at one time, all the equipment would be returned. Carla went to the original manufacturer of hydraulic pressure reducing valves again, and the manufacturer gave up, because the fluororubber seal ring was their best choice. Now Carla was worried and had to turn to her purchasing director for help. The director asked her to contact AAK hydraulic valves first. If AAK still cannot solve it, there will be no need to waste time on Chinese hydraulic pressure reducing valve manufacturers and can only purchase from Germany.

After receiving the email, AAK replied that she should not worry. According to the drawing parameters of her hydraulic pressure reducing valve, it matches a hydraulic pressure reducing valve used in aircraft completely that AAK produced for a Russian customer reorder some time ago. We still have some quantity in stock, and can ensure that AAK hydraulic pressure reducing valves will not be reported for repair for at least one year. The next day, AAK sent 10 hydraulic pressure reducing valves to Kuala Lumpur Airport.

Carla emailed us a few days ago that after using AAK hydraulic pressure reducing valves, the equipment has been running smoothly for 6 months,
