Butterfly Valve Hydraulic Test bench
Mostly apply to the seal pressure of the Butterfly valve body shell pressure performance test.
Adopt the synchronized contracting & pressing clamp (divide into single and combination)
Equip with the high and low pressure water pump pressure supply device in system,the test medium circulating storage use.
Pressure suitable medium is water, air and kerosene depends on the user.

 | | Keywords (seperated by comma) | valve test bench | | Product Specifications | Working principie and using method of the JLD type hydraulic butterfly valve test desk
JLD type butterfly valve test desk is the testing equipment exclusively for butterfly valve performance test. The machineintegrates the mechanical, electric, hydraulic and hydrodynamic pressure feed device circulating water system. The clamp claw of the test desk realize the test by clamping the butterfly valve through being driven by cylinder, making each claw stressed evenly and reliably. The function of moving towards radial direction of the clamp claw adopts cylinder and connecting rod level to realize the synchronous movement, ensuring the tests of butterfly valves of different latus rectum. When test on sealing, clamp the flange of the butterfly valve with flange, clamping the butterfly valve surface can test the butterfly valve without flange. The machine can directly observe whether there is leakage or bubbling in the cavity of the butterfly valve. If testing on intensity, cover the sealing blank plate.Torque test and test of open and close in 90~ of the electric device can be performed on the machine. The machine is provided with
hydraulic water-supply pump. The medium can be stored used circularly. When using clean water, it should add antirust to prevent the valve rust after test and influence the using performance of the hydraulic pressure-feeding device.
Using method:
1、 inject 30#-40#hydraulic oil or 20# mechanical oil into the cylinder of hydraulic system, the oil amount should not less than the lower limitation of the oil level indicator.
2、 connect the power, push the start button of the oil pump, and check whether the rotating direction of the motor is correct.
(Clockwise)
3、 adjust the pressure of hydraulic system to 5.0Mpa to work normally.
4、 working procedure: (1) inch the clamp claw to the maximum position; (2) put the tested butterfly valve on the center of thesealing disk of work table; (3) inch the clamp claw to the needed position on the tested butterfly valve; (4) inch the clamp claw, clampthe tested butterfly valve (flange or surface); (5) press pressure increasing button to the desired pressure (clamp cylinder neededpressure reference list) (stick on the machine). Pressure-increasing button can be inched for many times with the interval of 3seconds between inching (when first inching can not reach the desired pressure). The maximum pressure is 32Mpa; (6) test thetested butterfly valve with water pressure and air pressure; (7) open the water or air outlet switch to let go the pressure after test; (8)press the release buttons by turns to take the tested valve down.
Use attention and requirement
1、Installation of equipment: adjust the allocation level of the equipment or fix the foundation bolts by concrete.
2、 adopt N32-46# normal hydraulic oil, N32-46# antifriction hydraulic oil or 20-30# mechanical oil, inject into the cylinder, the quantity of the oil should not less than the lower limitation of the oil level gauge.
3、 connect the power; press the start button of the oil pump. Check the rotating direction of the motor to see whether it is no-load running correctly (clockwise) for 5-10 minutes. Adjust the pressure of oil pump to 5.0Mpa to test the machine in every motion; check whether there is leakage in the pipes. If abnormal situation is found, stop the machine and solve the problem immediately.
4、 medium of test: water is widely used because it is convenient and has no pollution to the environment. Make sure the tested valve won?t be corrupted. Add antirust into the water tank or use normal oil as test medium.
5、 adjust the pressure according to the tested valve?s testing pressure during testing, refer to the pressure value of hydraulic clamp system in . It is not allowed to adjust the pressure too high and prevent the valve to be damaged and distorted.
6、 Adjust the electric contact pressure gauge and tested valve to the same before hydraulic pressure feeding water pump, then start to work.
Do not hammer the cast iron valve. The operators should pay attention to safety during test and operate correctly; especially pay attention to the pressure of medium during cast iron valve test, it may cause damage. Exhaust the inner pressure of the valve before loose the axial press.
7、The pressure gauge of the pressure test device should be verified by the local calibration authority, and its certificate of conformity should within the useful life. The range of pressure gauge should not less than the tested pressure by 1.5 times. The precision should not lower than 1.5 Class.
8、 Cautions
①Work surface of test table should keep clean. Foreign objects are not allowed between flange of tested valve and sealing disk.Often check whether the O shaped loop is damaged.
②All the moving parts of the test table should be lubricated often, keep it clean and lubricated.
③the hydraulic oil should be examined and replaced regularly. As for the equipment put into usage newly, first time should cleanthe cylinder and change the oil 3 months later, and then clean it and replace the oil once per year. The quantity of oil should not less than the lower limitation of the oil gauge. The oil temperature in the cylinder should not exceed 55℃.
