Small four wheel brake valve malfunction of the correct treatment
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. When the outer diameter of the tappet becomes larger, it will cause a jam in the gas brake valve housing failure, so that the valve body can not open, no air, no air, or in the open position does not return, not inflated , No pressure; when the tappet length becomes shorter, the valve body parts open fishing, no air, no deflation. When the tappet diameter becomes larger, the length becomes longer, the fine sandpaper can be gently polished after loading complex pull test until meet the requirements so far; when the tappet becomes shorter, the tappet head and the valve body between the election pad Thickness of 1mm ~ 2mm, φ18mm outer diameter of the ordinary flat pad 1 or 2 can be. Of course, fundamentally solve the problem or to improve the tappet material and dimensional accuracy. This article Keywords: valve
