① When cutting the plate, it is best to cut the root of the plate on a round steel rod with the same diameter of the valve stem to ensure that the size is correct and the incision is parallel. The incision should be neat, without a loose asbestos. The optimal incision is best at 45 ° angle.
② Each root ring should be put into the root box separately. When the root root of the stress valve, a small amount of scale dry graphite powder or lubricant should be placed between each circle.
③ In order to facilitate the installation, when the aluminum foil is packed with the root of the asbestos, it should be applied to a thin layer of the scaled graphite powder blended with oil on the inside of the plate.
④ The width of the plate root should be consistent with the size of the plate root box, or 1 to 2 mm in large.
⑤ When the roots of impulse oil are immersed, it is best to put dry stone cotton plates in the first and last laps to prevent oil from exuding.
⑥ When pressing the root of the dish, the interface of the plate rings must be staggered. Generally, the interface is staggered by 120 ° or 180 °;
⑦ The depth of the pressed cover into the root box is generally the height of a turning root, but it must not be less than 5, and there should be a room to spin again.
⑧ When installing the cover cover, the gap between the plate roots and the valve stem should be consistent, preventing the pressure bias, so that the root of the plate root should be uneven and quickly worn out. Generally, the gap should not be greater than 0.1 to 0.15.
⑨ The main point of ensuring the quality of the plate roots is: the selection is right; the check is checked (check the valve stem, the plate root box, the plate root, etc.); the size is accurate; Each lap of the plate is deformed like the same, the thickness is consistent).
