Suncenter Valve test bench, meets DN50-300 straight through welding gate valve, ball valve, globe valve, check valve.
Introduction:
The SST-H600 hydraulic valve test bench is based on our company's many years technology of producing valve testing equipment, strictly in accordance with the ISO9001 quality management system for management and production. According to GB/T13927-2008 "General Valve Pressure Test", GB/T26480-2011 "Valve Test and Inspection" and AP1598 American Standard and other relevant standards.
The hydraulic valve test bench is a combination of hydraulic, mechanical, electrical and medium storage cycle. It has the advantages of reasonable structure, perfect function, stable performance and high degree of automation. At the same time, it is widely used in the test of high, medium and low pressure sealing and strength of straight through flange or welded valve with nominal diameter of DN50-300mm. It is also used in valve manufacturing, petroleum and petrochemical industry Natural gas, water supply and drainage engineering, power plants, valve repair stations and other industries the most ideal valve test equipment.
SST-H300 model instruction and working principle
1 SST-H300 Hydraulic valve test bench consists of hydraulic system, electrical control system, high & low pressure water pump pressure supply device system, oil pressure, water pressure instrument system, control valve system, clamping table system and hydraulic medium storage circulating water tank. The test process and results meet the relevant regulations and requirements.
2 The test bench adopts end face O-ring seal, and the jacking oil cylinder is directly tightened by the end face of the valve tested. The jacking oil cylinder is directly driven by hydraulic pressure. It can be pushed in and out in the axial direction without the limitation of structure length. There is a large distance between the pull rods and is not limited by the diameter of valve flange.
3 The high-pressure water pump is powered by 4-7bar air pressure system, and automatically reverses by electric control reversing valve, which makes the high-pressure pump automatically reciprocating. The pressure is continuously supplied to the tested valve by using the exchange of water suction check valve and outlet check valve, which meets the pressure requirements of the tested valve.
4 Working process: According to the valve's nominal diameter and adjust the compression pressure of the oil cylinder(refer to the pressure comparison table)--compress the work-piece--turn on the low pressure water pump for quick water injection--turn on the high pressure water pump--turn on the pressure holding timer--pressure relief, reset.
5 Set the compression oil cylinder and the medium pressure interlock function: when there is pressure in the test valve cavity, the compression oil cylinder cannot be loosened. Prevent operation failure play a protective role in the wrong time.
6 The buyer need to prepare 46# anti-wear hydraulic oil, 8bar air source and cable
7 Equipment dimensions: 3300mm long × 950mm wide × 1800mm high, weight approximately: 3000Kg
Mainly parameter:
Meet DN50-300 straight through welding gate valve, ball valve, globe valve, check valve
1. Test valve type: straight-through flanged gate valve, ball valve, globe valve.
2. Clamping method: the hydraulic cylinder is horizontally pressed and the end face is sealed, which has minimal influence on the external force of the valve.
3. Valve and blind plate sealing method: end face O-ring seal or cone seal.
4. Pressure test medium: water or 4-7bar air pressure test.
5. Complete the test items: 1.5 times the nominal pressure of the water pressure shell pressure test, 1.1 times the nominal pressure of the high pressure water seal test, 4-7bar low pressure air tightness test.
6. Test range: DN50-300, see the pressure test range table.
7. Test valve structure length: 178-762mm. Maximum meeting diameter: 405mm
8. The distance between the sealing discs: 170-850mm.
9. Interval between tie rods: 670mm
10. Top pressure cylinder: ∅150mm
11. Maximum top pressure: 50 tons.
Pressure testing range:
Meet the requirements of straight-through welded ball valves, gate valves and stop valves.

Equipment structure outline:
Function configuration of water and gas pipeline:
- This test bench is equipped with a high and low pressure medium water pump. The low pressure pump is a vortex self-priming pump with high flow pressure. The full load pressure of the low pressure pump is 0-1.6Mpa. The power source of the high pressure pump is 4-7bar air pressure system reciprocating drive The pressure value of the piston and high-pressure pump is 1.6-10.0Mpa. When the tested valve reaches the required test pressure value, it has an automatic stop function. The bottom of the machine circulates the storage medium water tank, and puts the anti-rust agent (powder) in the water tank to avoid rust and corrosion of the tested valve and the pipeline one-way valve. This test bench is the most ideal equipment for water saving and environmental protection.
2. The water and gas pipeline is designed with two-way pressure inlet and pressure relief, and the designed pressure holding time is up to the sound and light alarm.
