JLA type safety valve performance test table is the first JLA type safety valve performance test table designed and developed by the scientific and technical personnel of our company according to the requirements of national standard GB/T13927-92 and ZBJ16006-90, combining our technical experience of valve test equipments for many years. The machine is appraised by experts after being used in Maoming petrochemical inspection and repairing company and Zhenhai oil refining factory. The test table dispenses with the traditional high-pressure gas tank with huge volume, it only to be provided with gas source of 0.6MPAa normalgas pump. It will automatically adjust to 0.6-32.0 MPa gas source by the machine, it is applicable to the setting up, open and close, blowdown pressure tests of safety valve with inside nominal diameter DN15-300mm. It has the characters such as stable performance, convenient usage, high level of automation and precise measured data.
Remarks: the pressure feeding range of YFC-A (normal type) safety valve performance test table should be prepared by the user, and use it according to this manual. There is no other using manual provided.
Work Principle and structure
JLA type safety valve performance test table is combing the mechanical, electric and hydraulic machine together, with gas as the test medium, increasing the pressure by linkage of gas and liquid, provided with multi-stage pressure increasing device system. The function fulfills the test pressure needed in the test. The clamp of work piece is oriented by the flange end surface of tested valve,hydraulic cylinder clamp claw clamp the backside of flange. There is no effect of external force to the tested valve, completely fulfill the requirements of valve test and inspection stipulated by national standards.
The machine is composed of hydraulic system, mechanical part, electric control and multi step gas source device system. Hydraulic system is the main source of power of the test table. The clamp claw is driven by hydraulic cylinder directly. Axial clamp pressure is adjusted and increased according to different testing pressure class (maximum hydraulic pressure increase pressure is 31.5 MPa). Every clamp claw is force evenly and reliably. The radial movement is driven by hydraulic cylinder, every clamp claw
forward and back at the same time, flexibly and fast, ensure the usage of valves with different latus rectum. Multistep gas source pressure increasing device adopts liquid and gas linkage to increase pressure. The range is 0.6-32.0 Mpa, used for valve medium pressure test. There are alternative auto and manual operation. When choosing auto pressure increase, the operator can leave the control panel and observe the test situation in near distance.
The safety device of the test table is controlled and increased pressure by gas source regulating valve during gas source pressure increase. The electric contact pressure meter indicate stop machine.
Cautions and safety requirements
1、 the hydraulic control system and worktable should leave certain distance during installation of equipment, the space between should not less than 500mm. Adjust the installation level and fix the foot screw by concrete.
2、 add 30-40# hydraulic oil into cylinder, the oil quantity should not less than lower limit of the oil level meter.
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、 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.
5、 Adjust the electric contact pressure gauge and tested valve to the same before hydraulic pressure feeding water pump, then start to work. The high pressure test should refer to , and then perform pressure increase, when the pressure reach to desired value, the oil pump stops automatically.
6、 Air filter should be examined and exhausted at on and off duty. The exhausted holes at pipe gas tank, should be exhausted regularly every week.
7、 the test table sealing-disk and tested valve contacting surface should keep clean. Oil or other foreign objects are not allowed. People are forbidden to close to the machine during operation.
8、 the hydraulic oil should be examined and replaced regularly. As for the equipment put into usage newly, first time should clean the cylinder and change the oil 5-6 months later. The oil temperature in the cylinder should not exceed 60℃.
9、 the operation disobeying the stipulations is not allowed.
