今天来给大家介绍下混凝土搅拌车的换向阀部分，它是控制搅拌罐正转和反转的关键部分。是实现液压油的流动、切断和换向控制的阀门，根据液压油流通的方向控制混凝土搅拌车的搅拌罐正、反方向转动的。

Today, I'd like to introduce the reversing valve of concrete mixer, which is the key part to control the forward and reverse rotation of mixing tank. It is a valve to realize the flow, cut-off and reversing control of hydraulic oil. According to the flow direction of hydraulic oil, it controls the mixing tank of concrete mixer to rotate in the positive and negative directions.

那么怎样提高混凝土搅拌车的换向阀使用寿命和工作效率？那么必不可少的就是保养了，我们日常保养的好，换向阀的使用寿命就越长，工作效率自然就越高。

So how to improve the service life and efficiency of the reversing valve of concrete mixer? So essential is maintenance, our daily maintenance is good, the longer the service life of the directional valve, the higher the work efficiency.
           

在日常的保养上，一定要及时更换液压油，及时的更换液压油使液压油保持良好清洁度，可以减少细小杂物对换向阀的损害。在从正转改变反转或者从反转改变为正转的时候，先降低混凝土搅拌车搅拌罐的转速，不要在保持高转速的情况下突然改变转向。

In the daily maintenance, we must timely replace the hydraulic oil, timely replace the hydraulic oil to keep the hydraulic oil clean, can reduce the damage of small debris to the valve. When changing from forward rotation to reverse rotation or from reverse rotation to forward rotation, first reduce the rotation speed of the mixing tank of the concrete mixer, and do not change the direction suddenly while maintaining a high rotation speed.

定期的检查混凝土搅拌车的换向阀，看有没有进、排气孔被油泥或其他杂物堵塞，封闭不严等问题，及时检查换向阀的问题，并去还可以有效提高工作效率，以免它在关键的时候掉链子。

Regularly check the reversing valve of the concrete mixer to see if the inlet and outlet are blocked by oil sludge or other debris, and the sealing is not strict. Timely check and solve the problems of the reversing valve, which can also effectively improve the work efficiency, so as not to drop the chain at the critical time.
