小型攪拌機零件氣門的順利使用就要多多了解相關的內(nèi)容問題，比如說為了預防氣門的損壞，我們一般要知道這些方面要點：

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、氣門的光磨

1. Valve polishing

在攪拌機的維修中，如果氣門出現(xiàn)燒蝕、麻點及凹陷時，均應進行光磨，一般是在光磨機上進行，作業(yè)時需要注意四個問題：一是保證氣門頭與桿部同心，否則應先校直；二是光磨輛在能磨出完整的錐面的前提下是越小越好；三是盡量提高表面光潔度；四是氣門桿端部凹陷應予以磨平。

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、氣門導管的鉸銷

2. Hinge pin of valve guide

氣門桿與氣門導管配合間隙是決定氣門導管使用壽命的關鍵，因此當更換新的氣門導管時，鉸銷時應嚴格掌握好配合間隙，使用各攪拌機車型規(guī)定間隙的下限，可有效延長使用壽命。

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、氣門的研磨

3. Grinding of valve

氣門的研磨分為兩種情況：一是氣門與氣門座只有輕微麻點，不需要光磨和鉸銷時的研磨；二是氣門與氣門座均經(jīng)過光磨和鉸銷后的研磨。前者先用足金鋼砂研磨，將麻點研磨掉后，再用細金剛砂研磨，后涂上機油研磨，直密封符合要求，寬度符合規(guī)定為止。后者只有密封性達不到要求時才進行研磨，但操作時一定要注意，不要過分用力，嚴禁將氣門上下敲打，否則將出現(xiàn)凹形砂痕，影響維修質(zhì)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.
