減壓閥是通過調(diào)節(jié)，將進口壓力減至某一需要的出口壓力，并依靠介質(zhì)本身的能量，使出口壓力自動保持穩(wěn)定的閥門。從流體力學的觀點看，減壓閥是一個局部阻力可以變化的節(jié)流元件，即通過改變節(jié)流面積，使流速及流體的動能改變，造成不同的壓力損失，從而達到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié)，使閥后壓力的波動與彈簧力相平衡，使閥后壓力在一定的誤差范圍內(nèi)保持恒定?；拘阅?1)調(diào)壓范圍：它是指減壓閥輸出壓力P2的可調(diào)范圍，在此范圍內(nèi)要求達到規(guī)定的精度。調(diào)壓范圍主要與調(diào)壓彈簧的剛度有關。(2)壓力特性：它是指流量g為定值時，因輸入壓力波動而引起輸出壓力波動的特性。輸出壓力波動越小，減壓閥的特性越好。輸出壓力必須低于輸入壓力—定值才基本上不隨輸入壓力變化而變化。(3)流量特性：它是指輸入壓力—定時，輸出壓力隨輸出流量g的變化而變化的持性。當流量g發(fā)生變化時，輸出壓力的變化越小越好。一般輸出壓力越低，它隨輸出流量的變化波動就越小。調(diào)壓步驟1、關閉減壓閥前的閘閥，開啟減壓閥后的閘閥，制造下游低壓環(huán)境；2、將調(diào)節(jié)螺釘按逆時針旋轉(zhuǎn)至上位置（相對出口壓力），然后關閉減壓閥后閘閥；3、慢慢開啟減壓閥前的閘閥至全開；4、順時針慢慢旋轉(zhuǎn)調(diào)節(jié)螺釘，將出口壓力調(diào)至所需要的壓力（以閥后表壓為準）；調(diào)整好后，將鎖緊螺母鎖緊，打開減壓閥后閘閥；5、如在調(diào)整時出口壓力高于設定壓力，須從步開始重新調(diào)整，即只能從低壓向高壓調(diào)。DBD溢流閥R900423712，DBDS30P1X/100R900423713，DBDS30P1X/100VR900423714，DBDS30P1X/200R900423715，DBDS30P1X/315R900423716，DBDS30P1X/50R900082639，DBDS10K1X/25P15R900208779，DBDA2K2X/315R900331916，DBDH10K1X/630VR900334105，DBDA6K1X/315VR900334729，DBDH20K1X/25VR900340153，DBDS10G1X/25V/12R900340488，DBDS10G1X/315V/12R900341066，DBDS6G1X/200/12R900341363，DBDS10G1X/100/12R900341591，DBDS10G1X/200/12R900342738，DBDS10G1X/400/12R900343869，DBDH10K1X/400VR900343871，DBDH6G1X/200V/12R900343963，DBDS10G1X/200V/12Z2S疊加式液控單向閥此類單向閥即使長時間工作仍可保持一個或二個工作油口無泄漏封閉。通徑6，6X系列工作壓力為315Bar流量為60L/min特征-疊加設計-安裝面板按DIN?24340?A型，不帶定位孔標準型-安裝面按ISO?4401-03-02-0-94（帶定位孔）-一個或兩個工作油口可無泄露密封，可選-用于多層疊加系統(tǒng)-3種不同的開啟壓力，可選擇力士樂單向閥閥-NG6R900347495	?Z2S6-1-6X/R900347504	?Z2S6-1-6X/VR900347496	?Z2S6-2-6X/R900347505	?Z2S6-2-6X/VR900347497	?Z2S6-3-6X/R900347506	?Z2S6-3-6X/VR900347498	?Z2S6A1-6X/R900347507	?Z2S6A1-6X/VR900347499	?Z2S6A2-6X/R900347508	?Z2S6A2-6X/VR900347500	?Z2S6A3-6X/R900347509	?Z2S6A3-6X/VR900347501	?Z2S6B1-6X/R900347510	?Z2S6B1-6X/VR900347502	?Z2S6B2-6X/R900347512	?Z2S6B3-6X/VR900347511	?Z2S6B2-6X/VR900347503	?Z2S6B3-6X/力士樂單向閥-ng10R900407394	?Z2S10-1-3X/R900407439	?Z2S10-1-3X/VR900421985	?Z2S10-2-3X/R900436801	?Z2S10-2-3X/VR900431003	?Z2S10-3-3X/R900440349	?Z2S10-3-3X/VR900420049	?Z2S10-4-3X/R900506366	?Z2S10-4-3X/VR900407424	?Z2S10A1-3X/R900407440	?Z2S10A1-3X/V力士樂減壓閥ZDR6DP2-43/210YM6通減壓閥ZDR6DP2-43-150YMZDR6DB2-43/150YMDR6DP2-53/210YM力士樂?線圈R9000213894WE6H62/EG24N9K4MVPM22-160萬福樂?無泄漏換向閥AS32060B-G24DBW10B2-5X/200-6EG24N9K4萬福樂?無泄漏換向閥AS32061A-G24DB10-2-50/200Z2S6-2-64/4WE6D6X/OFEW230N9K4DGMC2-3-AB-FW-BA-FW-30DG4V-3-2C-M-U-H-60DG4V-3-6C-M-U-H-40壓力繼電器HED8?OP12/200K14力士樂?放大器VT-11118-10HED8OA-2X/350K14AS力士樂?壓力繼電器HED8OA-20/350K14S3WE6A6X/EG24N9K4HED8OP-10/100??Z14力士樂葉片泵PV7-18/63-71RE07MCO-16力士樂泵A10VS0140DR/31R-VPB12N00ASCO線圈400425-142SDSPM22-AB-G24/KAM22100B-G24SVSPM33-DC-G24/KSVSPM33-BC-G24/WDSCG353A051?220VAM22061A/G244WE6D61/EG24N9K4AM22060B/G24力士樂插頭R900019793LFA?32H2-71/FDBW?10?A2-52/315-6EG24N9K4A10VSO140DFR1/31R-PPB12N00DB10-1-5X/315A10VSO45DFR1/31R-PPA12N00SL6PB2-6XAS32061A-G24ZDR減壓閥R900323664	ZDR6DP0-4X/40YMVW80R900400451	ZDR6DA1-4X/75Y/12R900400663	ZDR6DP2-4X/210YMVR900401090	ZDR10DP3-5X/210YMR900401215	ZDR6DP1-4X/25YM/12R900401216	ZDR6DP2-4X/75YM/12R900401222	ZDR6DA2-4X/210Y/12R900401236	ZDR10DP2-5X/210YM/5R900403675	ZDR10DB1-5X/150YMR900404346	ZDR6DP2-4X/25YM/12R900404754	ZDR6DP2-4X/150YM/12R900404886	ZDR10DP2-5X/75YM/5R900404887	ZDR10DP2-5X/150YM/5R900406178	ZDR10DA1-5X/150YR900406225	ZDR10DA2-5X/150YMR900406651	ZDR10DA2-5X/210YR900407334	ZDR10DA2-5X/25YR900408340	ZDR10DB2-5X/150YMR900409965	ZDR6DP1-4X/25YMR900409966	ZDR6DA1-4X/75YR900409967	ZDR6DP1-4X/75YMR900409981	ZDR6DA1-4X/150YR900410806	ZDR6DP1-4X/150YMR900410808	ZDR6DA2-4X/25YR900410813	ZDR6DA2-4X/75YR900410815	ZDR6DA2-4X/75YMZ1S單向閥R900334980	Z1S10T2-3X/VR900334981	Z1S10T3-3X/VR900334982	Z1S10C2-3X/VR900334984	Z1S10D2-3X/VR900334985	Z1S10D3-3X/VR900334988	Z1S10B2-3X/VR900334990	Z1S10P2-3X/VR900334991	Z1S10P3-3X/VR900334992	Z1S10E2-3X/VR900334994	Z1S10F2-3X/VR900334995	Z1S10F3-3X/VR900417571	Z1S6A1-3X/VR900417590	Z1S10P1-3X/VR900417591	Z1S10T1-3X/VR900417592	Z1S10C1-3X/VR900417593	Z1S10A1-3X/VR900417594	Z1S10B1-3X/VR900417595	Z1S10D1-3X/VR900417596	Z1S10E1-3X/VR900417597	Z1S10F1-3X/VR901085992	Z1S6E05-4X/VR901086018	Z1S6E30-4X/VR901086037	Z1S6F05-4X/VR901086039	Z1S6F30-4X/VR901086051	Z1S6P05-4X/VR901086052	Z1S6P30-4X/VR901086055	Z1S6P50-4X/VR901086058	Z1S6T05-4X/VR901086059	Z1S6T30-4X/VR901086070	Z1S6A05-4X/VR901086077	Z1S6B05-4X/VR901086081	Z1S6C05-4X/VR901086086	Z1S6C30-4X/VR901086087	Z1S6C50-4X/VR901086090	Z1S6D05-4X/VR901086092	Z1S6D30-4X/VR901086602	Z1S6P05-4X/V/60R901104197	Z1S6P15-4X/VR901107146	Z1S6T05-4X/V/62R901112643	Z1S6P05-4X/V/62R901220126	Z1S6C15-4X/V
