先導(dǎo)壓力
外部先導(dǎo)泄油型的先導(dǎo)壓力必須始終過(guò)主壓港“P”的壓力。
多功能控制閥
DSLHG-12/6月10日
先導(dǎo)泄油口
Avoid connecting the pilot drain port to a line with possible surge pressure.
Drain Connection when with Counterbalance Function
When a valve having counterbalance function is used with internal
drain type, the counterbalance pilot valve is subjected
to pressure fluctuation and the pressure
setting becomes unstable. For this reason, be sure to use external drain type
避免先導(dǎo)泄油口連接到可能出現(xiàn)的沖擊壓力線。
漏連接時(shí)動(dòng)態(tài)平衡功能
當(dāng)一個(gè)具有閥平衡功能與內(nèi)部漏型用的背壓控制閥進(jìn)行
壓力波動(dòng)和壓力設(shè)定變得不穩(wěn)定。為此,一定要使用外部漏型
閥。
流程調(diào)整
為了進(jìn)行流量調(diào)節(jié),松開鎖緊螺母,然后順時(shí)針流量調(diào)節(jié)螺絲轉(zhuǎn)向降
流。請(qǐng)務(wù)必在調(diào)整后重新鎖緊螺母擰緊。
The tim ing of flow path opening/closing can be adjusted as required
by selecting the appropriate pilot orifice diam eter. W hen the diam eter
of the orifice is to be changed, another orifice should be ordered.
Standard built-in orifice diam eters and selectable orifice diam eters
are listed in the table below.
壓力調(diào)整
為了進(jìn)行壓力調(diào)整,松開鎖緊螺母,然后調(diào)節(jié)螺釘順時(shí)針轉(zhuǎn)壓力加大
壓力。請(qǐng)務(wù)必在調(diào)整后重新鎖緊螺母擰緊。
分鐘。在韻律出控制的時(shí)間來(lái)控制流量的類型“2”和“4A”
在節(jié)流控制時(shí)的小受控流被限制為(在此節(jié)流控制期間不發(fā)生)
在先導(dǎo)控制類型的情況下只有該圖所示“2”(DSLHG - * - 2)和“4A”(DSLHG - * - 4A)
