Product Description
The driving device of bevel gear plate valve can be electric, pneumatic, manual, bevel gear rotation and other devices. The air filter, solenoid valve and sensor can be installed on the pneumatic device. If the above driving device is installed, the pneumatic device shall be specified in the contract.
Shell test and sealing test of bevel gear plate valve:
1. The shell test and sealing test medium of bevel gear plate valve are water (including preservative), kerosene or other suitable liquid with viscosity not greater than water.
2. The sealing pair is a non-metal sealed plug-in valve. The test and requirements of the sealed shell shall be in accordance with the provisions of GB/T13927-92 D.
3. The sealing pair is a metal sealed plate valve. If there is a sealing performance requirement, the leakage of the sealing test shall be calculated according to 1 × DNmm3/s. If there is no sealing performance requirement, this test shall not be done.
4. For the flashboard valve driven by electric, hydraulic and pneumatic devices, after the closing position is set, close it for 3 times and carry out shell and sealing tests according to the requirements of 1 and 3.
5, bevel gear plate valve cleanliness requirements are high.
6. Static pressure life test.
7, bevel gear plug valve static pressure life test times according to the provisions, other technologies to be in accordance with the provisions of JB/Z 234.
The bevel gear plate valve has the advantages of small fluid resistance, large applicable pressure, large temperature range, unrestricted medium flow direction, and good sealing performance.
