Valve Test Machine
The YDM Type machine has advanced stepless speed grinding rotation, follows the principle of machinery eccentric of revolution and rotation and has the functions of hydraulic auto-lifting shaft, auto-tightening of job parts and freely adjusting valve position. There are advantages of convenient operation, perfect function, flexible structure, advanced technique and high automation. The machine may accomplish sealing grinding of annular face for seat and disc to various valves. With accuracy: precision roughness for sealing face at 1.6 (Hardness at HRC 36-50), radius 15-30 Min, precision machining at 0.4 contact degree by above 80%.
YDM Type Hydraulic Valve Grinding Machine
YFC-A type safety valve functional test machine is the first YFC-A type safety valve functional detector in China, developed successfully by our own scientific technicians, which refer to the advantages of foreign similar products according to national related standard requirements GB/ T13927-92 and ZBJ 16006-90 and integrate our many years¡¯ technical experience in producing valve detectors or equipment. It is appraised and affirmed by the experts after the machine is used by Maoming Petrochemical Maintenance Company and Zhenhai Refinery General Factory. This machine is not necessary to complete with traditional high pressure air storage tank of large volume, but only to have common air pump source of air pressure at 0.6Mpa. ...
YFC-A Type Safety Valve Function Test Machine
YFC-D Type butterfly valve test machine is the testing equipment exclusively for butterfly valve. The machine integrates electric, hydraulic, trial-pressure and liquid medium storage and circulation into one body. The clamp claw of the test machine realize the test by clamping the butterfly valve through being driven by cylinder, making each claw stressed evenly and reliably. The 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 the butterfly valve of different latus rectum. When test on sealing, clamp the flange of the butterfly with flange, clamping the butterfly valve surface can test the butterfly without flange. ...
