1、濟南裝載機http://www.lcsqtax.cn/入口單向閥負責從油泵來的高壓油經(jīng)單向閥進入轉向器的進油口，其作用是防止油液倒流，致使方向盤自動偏轉，造成轉向失靈。
Jinan loaders inlet check valve is responsible for the high-pressure oil from the oil pump to the steering gear through the check valve into the inlet, whose role is to prevent reverse flow,resulting in the automatic steering wheel deflection, causing steering failure.

2、安全閥的主要功能是當壓力油到達安全閥設定壓力時，安全閥打開泄油，提供轉向系統(tǒng)壓力的安全保護。
The main function of the safety valve when the pressure of the oil reaches the set pressure of the safety valve, open the drain valve, steering system pressure to provide security.

3、濟南裝載機http://www.lcsqtax.cn/雙向過載閥主要負責當轉向油缸受到外部沖擊時，油缸內的壓力升高，壓力油到達過載閥設定壓力時，過載閥打開泄油，對轉向油缸實施過載保護。
Jinan loader when bidirectional overload valve is mainly responsible for steering cylinder when subjected to external shocks, the pressure within the cylinder increases, the pressure valve oil reaches the set pressure overload, overload valve open drain on the steering cylinder implement overload protection.

4、雙向補油閥的主要功能是當油缸一腔壓力高于過載閥調定的壓力時，過載閥卸荷，油缸另一腔的補油閥補油，從而保證了系統(tǒng)不致產(chǎn)生氣蝕現(xiàn)象。
Bidirectional up the oil valve main function is when the fuel tank of a cavity pressure is higher than the overload valve tone given pressure, overload valve unloading, fill up the oil cylinder to another oil valve chamber, thus ensuring the system will not generate cavitation.
