小型搅拌机零件气门的顺利使用就要多多了解相关的内容问题,比如说为了预防气门的损坏,我们一般要知道这些方面要点:
For the smooth use of the valve of small mixer parts, we need to know more about the relevant contents. For example, in order to prevent the valve from being damaged, we generally need to know the following points:
1、气门的光磨
1. Valve polishing
在搅拌机的维修中,如果气门出现烧蚀、麻点及凹陷时,均应进行光磨,一般是在光磨机上进行,作业时需要注意四个问题:一是保证气门头与杆部同心,否则应先校直;二是光磨辆在能磨出完整的锥面的前提下是越小越好;三是尽量提高表面光洁度;四是气门杆端部凹陷应予以磨平。
During the maintenance of the mixer, if the valve is ablated, pitted or dented, it should be polished, usually on the grinder. Four problems should be paid attention to during the operation: first, ensure that the valve head is concentric with the rod, otherwise it should be straightened first; Second, the smaller the smooth grinding vehicle is, the better on the premise that it can grind a complete cone surface; Third, try to improve the surface finish; Fourth, the depression at the end of the valve stem should be smoothed.
2、气门导管的铰销
2. Hinge pin of valve guide
气门杆与气门导管配合间隙是决定气门导管使用寿命的关键,因此当更换新的气门导管时,铰销时应严格掌握好配合间隙,使用各搅拌机车型规定间隙的下限,可有效延长使用寿命。
The fit clearance between the valve stem and the valve guide is the key to determine the service life of the valve guide. Therefore, when replacing a new valve guide, the fit clearance should be strictly controlled when hinge pin is used. The use of the lower limit of the specified clearance for each mixer model can effectively extend the service life.

3、气门的研磨
3. Grinding of valve
气门的研磨分为两种情况:一是气门与气门座只有轻微麻点,不需要光磨和铰销时的研磨;二是气门与气门座均经过光磨和铰销后的研磨。前者先用足金钢砂研磨,将麻点研磨掉后,再用细金刚砂研磨,后涂上机油研磨,直至密封符合要求,宽度符合规定为止。后者只有密封性达不到要求时才进行研磨,但操作时一定要注意,不要过分用力,严禁将气门上下敲打,否则将出现凹形砂痕,影响维修质量。
The grinding of valve can be divided into two situations: one is that the valve and valve seat have only slight pitting, and the grinding of smooth grinding and hinge pin is not required; The other is that the valve and valve seat are polished and reamed. The former is first ground with full emery, after the pitting is removed, it is then ground with fine emery, and then coated with oil for grinding until the sealing meets the requirements and the width meets the requirements. The latter shall be grinded only when the sealing performance fails to meet the requirements. However, care must be taken during operation to avoid excessive force. It is strictly prohibited to knock the valve up and down, or concave sand marks will appear, which will affect the maintenance quality.
