四川省遂宁市汽车配件厂是国内仅有的一家内燃机气门弹簧座的专业化生产厂。近年来该厂开发的专利新品——内燃机气门旋转机构,具有下述优点:可消除气门和气门座、气门导管间的积炭,防止“漏气”、“卡死”现象;改善磨损和热应力状况,延长气门、气门座、导管的寿命,提高整机的可靠性;维修、更换更简便,无需人工研磨。该厂在生产气门旋转机构中采用少、无切削的压力加工,产品表面光洁,尺寸稳定。热处理车间拥有先进的可控气氛连续式网带炉生产线,零件硬度均匀,变形很小,表面光亮,无氧化、
Suining City, Sichuan Province Auto Parts Factory is the only one of the internal combustion engine valve spring seat of the specialized production plant. In recent years, the plant developed patented new product - internal combustion engine valve rotation mechanism, has the following advantages: to eliminate valve and valve seat, the valve between the carbon deposition, to prevent “leakage”, “stuck” phenomenon; Improve the wear and thermal stress conditions, extend the valve, valve seat, catheter life and improve the reliability of the machine; maintenance, replacement easier, without manual grinding. The plant in the production of valve rotation mechanism used less, no cutting pressure processing, product surface smooth, dimensional stability. Heat treatment workshop has advanced controllable atmosphere continuous belt furnace production line, parts hardness uniformity, deformation is very small, bright surface, no oxidation,
