Maintenance of high and low temperature test chamber with one-way pneumatic valve have what use?

when the malfunctioning of the high and low temperature test chamber, you need to contact the manufacturer home maintenance. If equipment failure to add fluoride is not correct, there is also more or less, the maintenance staff will take a lot of tools, such as: freon cylinder, vacuum pump, welding, kit, such as some other maintenance tools, these tools cannot lack, its weight is also to be reckoned with. Thus maintenance personnel to bring unnecessary trouble, don't waste time and low efficiency. For this kind of problem you have to learn to skilful use of equipment one-way pneumatic valve, then someone will ask, one-way pneumatic valve when maintenance should be how to use? Announced the following for you:
high and low temperature test chamber the introduction of one-way pneumatic valve
when buying a one-way pneumatic valve to remove its pneumatic valve core, a one-way pneumatic valve and equipment technology of pipe welding. Determine welding without leakage, firm before the installation of the pneumatic valve core. When vacuum need to use the add fluoride with a thimble pipe connections, the other a head connected with the Angle of pneumatic valve, then the table with the vacuum pump. Vacuum has been completed, need to unload the vacuum pump, will add fluorine cylinder change, off second fluoridated tube ( Angle after the air in the pneumatic valve, add fluoride.
when the end of the test chamber and fluorine, need to close the pneumatic valve Angle and will need to add fluoride cylinder unloaded, the final step to unload a one-way pneumatic valve after add fluoride with thimble tube, with the hard sealing one-way pneumatic valve.
a one-way pneumatic valve, when there is 'more fluoride' high and low temperature test chamber, or 'little fluoride', only need to remove the hard, from one-way pneumatic valve pneumatic valve core is directly put fluoride or fluorine. This also reduces the trouble for maintenance personnel, enabling them to travel light.
