搅拌车在工程建筑中起着关键性的作用，它所运输的混凝土配比更加科学，搅拌更加均匀，工作效率也很高，这也是搅拌车在市场受欢迎的原因。

The mixer truck plays a key role in engineering construction. The concrete ratio it transports is more scientific, the mixing is more uniform, and the work efficiency is also very high, which is also the reason why the mixer truck is popular in the market.

自上料水泥搅拌车上有很多的部件，这些部件各司其职，共同完成搅拌车作业，每个部件都有它独特的作用，比如液压阀，搅拌车上的液压阀有很多，不同的液压阀作用不同。搅拌车的液压阀是用来控制液压油的流动方向、流量和压力的，依次可以实现液压机械在不同作业情况下的动作要求。大致可以分为三类：

There are many parts on the self feeding cement mixer. These parts perform their own duties and work together to complete the operation of the mixer. Each part has its own unique function, such as hydraulic valves. There are many hydraulic valves on the mixer, and different hydraulic valves have different functions. The hydraulic valve of the mixer is used to control the flow direction, flow and pressure of the hydraulic oil, which can successively meet the action requirements of the hydraulic machinery under different operating conditions. It can be roughly divided into three categories:

1. 压力控制阀：搅拌车的压力控制阀是用来控制或调节液压系统中的液压油压力的阀类，如阀、溢流阀、背压阀等。

1. Pressure control valve: the pressure control valve of the mixer is used to control or regulate the hydraulic oil pressure in the hydraulic system, such as safety valve, overflow valve, back pressure valve, etc.

2. 流量控制阀：搅拌车的流量控制阀可以使液压油的流量维持在一定的数值，用以调节工作机构的运动速度，比如节流阀、行程控制阀等。

2. Flow control valve: the flow control valve of the mixer can maintain the flow of hydraulic oil at a certain value to regulate the movement speed of the working mechanism, such as throttle valve, travel control valve, etc.

3. 方向控制阀：搅拌车的方向控制阀可用于控制液压油流动的方向，有换向阀和单向阀两种，换向阀又分为滑阀和转阀两种，在液压操纵机械中，用得多的是换向阀，为了减少换向阀的安装体积，便于油路连接，往往将几个换向阀和阀安装在一起，或将阀体做成一个整体，称为多路换向阀。

3. Directional control valve: The directional control valve of the mixer can be used to control the direction of hydraulic oil flow. There are two kinds of directional control valve and one-way valve. The directional control valve is divided into slide valve and rotary valve. In hydraulic control machinery, the directional control valve is used more frequently. In order to reduce the installation volume of the directional control valve and facilitate the connection of the oil circuit, several directional control valves and safety valves are often installed together, or the valve body is made into a whole, which is called the multi-channel directional control valve.

自上料水泥搅拌车的液压阀的保养有一定的原则：平时要做好混凝土搅拌车的日常保养，比如对元件进行“点检”、“专检”，发现问题，一定要采取相应的措施进行排除，以保证各液压阀和液压系统的正常工作，如果是液压阀出现故障，一定要先找出故障原因。

There are certain principles for the maintenance of the hydraulic valve of the self feeding cement mixer: the daily maintenance of the concrete mixer shall be done well at ordinary times, such as "spot inspection" and "special inspection" of the components. If problems are found, corresponding measures must be taken to eliminate them, so as to ensure the normal operation of each hydraulic valve and hydraulic pressure system. If the hydraulic valve fails, the cause of the failure must be found first.

如果自己不了问题，那就找近的维修站去进行修理，且不可盲目的拆卸维修，否则很可能会造成更加严重的后果。更多相关注意事项就来我们网站http://www.sdzkjf.cn进行咨询。

If you can't solve the problem yourself, go to the nearest maintenance station for repair, and do not dismantle and repair blindly, otherwise it is likely to cause more serious consequences. More relevant precautions come to our website http://www.sdzkjf.cn Consult.
