Important notes:• Before ordering a design tested pressure relief

valve, checks have to be carried out to ensurethat at the requiredresponse pressure pthe maximum permissible flow qVmax of thesafety valve is greater than the maximumpossible flow from the system!The appropriate regulations must be taken intoaccount.

• The return lines (ports T and Y) from safetyvalves must vent in a safe manner. Fluid mustnot be able to gather in a venting system.

• The removal of the seal from a safety valveinvalidates the DGRL approval!

• The requirements of the pressure componentdirective 97/23/EG and the AD2000information sheet A2 must be taken intoaccount !

Directional valve, normally closed = ADirectional valve, normally open = B

重要注意:

‧在訂購一台經過設計認証的溢流閥之前,必須進行檢查,來保証在要求的響應壓力p下

安全閥的最大允許流量qVmax大於來自系統的最大可能流量。

必須遵守相應的規則!

‧安全閥的回油管(油口T和Y)必須以安全的方式排放,油液一定不能匯集到一個排放管路中。

‧拆下安全閥的印封,DGRL的認可無效!

‧必須考慮壓力元件指南和樣本AD2000-

按照DGRL 97/23/EG,由於流量的關係,系統壓力必須不能

高於設定響應壓力(見元件號)的10%。

必須考慮使用注意事項!

元件號中給出的響應值是制造廠在2 L/min流量下設定的。

必須不能超過在元件號中給出的最大允許流量qVmax。(=在

元件號中„G”位置中的數值,見4頁)。

適用:

- 先導油“外排”(= Y,在訂貨代號中),在先導回油管中沒

有背壓,在回油管(油口 T)中允許的背壓 < 15 bar

- 先導油“內排”(= 無代號,在訂貨代號中),允許的最大流

量只有在回油管(油口 T)無背壓下才是容許的。

採用先導油內排,系統壓力隨流量加大而增加了回油管(油口

T)內的背壓值。(考慮樣本AD2000-A2中的要點6.3)

由於流量的關係,要保証系統壓力不能高於設定響應壓力的

10%,允許的流量必須相對於回油(油口 T)管中的背壓而減

小(見下面的圖)。

功能說明、剖面圖:DB...型

概述:

DB 和DBW型壓力控制閥是先導式溢流閥。

它們用於限制(DB型),或用電磁鐵限制及卸荷系統壓力(DBW型)。

該溢流閥(DB型)的組成主要包括帶主閥芯插件(3)的主閥(1)和帶壓力調節元件的先導閥(2)。

DB型溢流閥

油路A中的壓力作用於主閥芯(3)上。同時,壓力經帶節流孔(4)和(5)的控制通路(6)和(7),作用在主閥芯(3)的彈簧加載側及先導閥(2)的球(8)上。如果A口的壓力超過彈簧(9)的設定值,球(8)克服彈簧力(9)而使先導閥開啟。

該信號經控制通道(10)和(6)從A口內部獲取。主閥芯(3)彈簧加載側的油液經過控制通路(7)、節流孔(11)和球閥(8)流入彈簧腔(12)。對DB...-5X/..-..型它由控制通路(13)內部引入油箱,而對DB..5X/..Y..型經控制通路(14)它由外部引入油箱。節流孔(4)和(5)在主閥芯(3)兩端產生壓降,因此A到B

連接通道被打開。油液由A口流向B口,而設定工作壓力保持不變。

溢流閥借助油口X(15)可對不同壓力(二級壓力)卸荷或切換。

Pressure relief valve type DBW

The function of this valve is basically the same as the valve type DB.The unloading of the main spool (3) however is achieved by operatingthe built-on directional spool valve (16).

The degree of damping (unloading shock) is determined by the sizeof the orifice (18). The Ø 1.2 mm orifice is recommended (orderingdetail..R12..).

Pressure relief valve with switching shock damping(sandwich plate), type DBW…/..S6...R12

With a switching shock damping valve (17) the opening of theconnection from B2 to B1 is delayed. Pressure peaks and acousticunloading shocks in the return line are thereby avoided. It is fittedbetween the pilot control valve (2) and the directional valve (16).

帶切換時間延遲閥(17)使B2至B1的接通延時開啟。因此可

General guidelines

• The unloading function (directional valve function with the typeDBW) must not be used for safety functions!

• For type DBW..B..5X/... the lowest settable pressure is set if thecurrent fails or if there is a cable break (circulation pressure).For type DBW..A..5X/... the pressure relief function is activatedif the current fails or if there is a cable break.

• Hydraulic back pressures in port T with an internal pilot oil drainor in port Y with an external pilot oil drain are added 1:1 to theresponse pressure set at the pilot control of the valve.

Example:Valve pressure setting via the spring loading(Pos. 12 on page 7) in thepilot control valve/adjustment unit pspring = 200 bar

Hydraulic back pressure in port T with aninternal pilot oil drain phydraulic = 50 bar

=> Response pressure = pspring + phydraulic = 250bar
