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 DN150-400mm. 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-B400 model instruction and working principle
1 SST-B400 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 the flange end face seal, and the clamping claw directly clamps the back of the valve flange to press. The clamping mechanism is directly driven by the clamping cylinder of the clamping claw to work. The clamping claw can advance and retreat in the axial direction without being restricted by the thickness of the flange. The radial movement is composed of an oil cylinder and a lever to realize the synchronous radial movement of each clamping jaw, and the radial clamping jaw can advance and retreat. It is not restricted by the diameter of the valve flange. No external force influence on the test valve
3 The left end of the test bench can move horizontally left and right, and the pressure test is not limited by the length of the test valve structure; the right end can be turned over 90 degrees, which is convenient for testing the sealing and air tightness of the valve.
4 The high-pressure water pump is powered by a 4-7bar system, and is automatically switched by the electrical control valve to make the high-pressure water pump automatically reciprocate. The water suction check valve and the water discharge check valve are interchanged to continuously supply pressure to the tested valve to achieve Test the pressure required by the valve.
5 Suitable for flanged valve 1.1 times the nominal pressure high pressure water tightness test, 1.5 times the nominal pressure high pressure water shell test, 4-7bar low pressure air tightness test.
6 Working process: Adjust the compression pressure of the cylinder according to the nominal diameter and pressure of the valve (refer to the pressure comparison table)-compress the workpiece-turn on the low water pump for quick water injection-turn on the high pressure water pump-pressure keeping timer-pressure relief, reset .
7 The mobile workbench is equipped with pressure pushing and powerless driving functions. Prevent damage to the equipment and valve when testing the valve.
8 Set the compression cylinder and the medium pressure interlock function: when there is pressure in the test valve cavity, the compression cylinder cannot be loosened. Prevent operation errors
Protects from time to time.
9 The buyer prepares 46# anti-wear hydraulic oil, 8bar air source, and cable
Main technical parameters: see the outline drawing of the accessory equipment for details:
1 Test valve type: straight-through flanged gate valve, ball valve, globe valve, check valve
2 Clamping method: clamping jaws clamp the back of the flange, no external force affects the valve
3 Sealing method of valve and blind plate: O-ring seal on the end face, which can observe the leakage position
4 Pressure test medium: water or 4-7bar low pressure gas (air or nitrogen)
5 Complete the test items: 1.5 times the nominal pressure shell test, 1.1 times the nominal pressure high pressure liquid tightness test; 4-7bar low pressure air tightness test

Water pipeline function configuration:
1 The 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 value of the low pressure pump is 0-1.6Mpa. The pressure value of the high-pressure pump is 1.6-30.0Mpa. When the tested valve reaches the required 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 pipeline check 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. Sound and light alarm
