1、濟(jì)南裝載機(jī)http://www.hdwzhs.com/入口單向閥負(fù)責(zé)從油泵來(lái)的高壓油經(jīng)單向閥進(jìn)入轉(zhuǎn)向器的進(jìn)油口，其作用是防止油液倒流，致使方向盤自動(dòng)偏轉(zhuǎn)，造成轉(zhuǎn)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(dāng)壓力油到達(dá)安全閥設(shè)定壓力時(shí)，安全閥打開泄油，提供轉(zhuǎn)向系統(tǒng)壓力的安全保護(hù)。
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(jì)南裝載機(jī)http://www.hdwzhs.com/雙向過(guò)載閥主要負(fù)責(zé)當(dāng)轉(zhuǎn)向油缸受到外部沖擊時(shí)，油缸內(nèi)的壓力升高，壓力油到達(dá)過(guò)載閥設(shè)定壓力時(shí)，過(guò)載閥打開泄油，對(duì)轉(zhuǎn)向油缸實(shí)施過(guò)載保護(hù)。
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(bǔ)油閥的主要功能是當(dāng)油缸一腔壓力高于過(guò)載閥調(diào)定的壓力時(shí)，過(guò)載閥卸荷，油缸另一腔的補(bǔ)油閥補(bǔ)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.
