Small four-wheel tractor air brake valve tappet is made of plastic, its diameter and length are often susceptible to the impact of thermal expansion and contraction change, resulting in failure of the gas brake valve. 1, the size changes and failures When the tappet diameter becomes larger, it will be in the gas brake valve housing to produce a stuck fault, so that the valve parts can not open, no air, no deflation, or in the open position Not return, no inflation, no pressure; when the tappet length becomes shorter, the valve body parts can not open, no air, no deflation. 2, the solution When the tappet diameter becomes larger, the length becomes longer, the fine sandpaper can be gently polished after the loading pull test until meet the requirements so far; when the tappet becomes shorter, tappet head and the valve body together Between the election pad thickness of 1mm-2mm, φ18mm outer diameter of the ordinary flat pads 1-2 can be. Of course, fundamentally solve the problem or to improve the quality of the tappet and the size of the village.
