攪拌車在工程建筑中起著關鍵性的作用，它所運輸的混凝土配比更加科學，攪拌更加均勻，工作效率也很高，這也是攪拌車在市場受歡迎的原因。

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.

自上料水泥攪拌車上有很多的部件，這些部件各司其職，共同完成攪拌車作業(yè)，每個部件都有它獨特的作用，比如液壓閥，攪拌車上的液壓閥有很多，不同的液壓閥作用不同。攪拌車的液壓閥是用來控制液壓油的流動方向、流量和壓力的，依次可以實現(xiàn)液壓機械在不同作業(yè)情況下的動作要求。大致可以分為三類：

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. 壓力控制閥：攪拌車的壓力控制閥是用來控制或調節(jié)液壓系統(tǒng)中的液壓油壓力的閥類，如安全閥、溢流閥、背壓閥等。

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. 流量控制閥：攪拌車的流量控制閥可以使液壓油的流量維持在一定的數值，用以調節(jié)工作機構的運動速度，比如節(jié)流閥、行程控制閥等。

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. 方向控制閥：攪拌車的方向控制閥可用于控制液壓油流動的方向，有換向閥和單向閥兩種，換向閥又分為滑閥和轉閥兩種，在液壓操縱機械中，用得多的是換向閥，為了減少換向閥的安裝體積，便于油路連接，往往將幾個換向閥和安全閥安裝在一起，或將閥體做成一個整體，稱為多路換向閥。

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.

自上料水泥攪拌車的液壓閥的保養(yǎng)有一定的原則：平時要做好混凝土攪拌車的日常保養(yǎng)，比如對元件進行“點檢”、“專檢”，發(fā)現(xiàn)問題，一定要采取相應的措施進行排除，以保證各液壓閥和液壓系統(tǒng)的正常工作，如果是液壓閥出現(xiàn)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.

如果自己解決不了問題，那就找近的維修站去進行修理，且不可盲目的拆卸維修，否則很可能會造成更加嚴重的后果。更多相關注意事項就來我們網站http://www.top2010.cn進行咨詢。
