進口氣動雙作用UPVC塑料隔膜閥

品牌：美國威盾VTON

進口氣動塑料PVDF隔膜閥由耐酸的塑料材質PVDF隔膜閥和氣動執行機構兩部分組成，它以壓縮空氣為動力，實與對工藝管道中流體介質的開關和流量的調節。

由于在結構上采用帶有耐腐蝕襯里的閥體和耐腐蝕的隔膜、無填料函結構、節流元件為彈性隔膜、閥體流道平滑，故氣動薄膜隔膜閥具有陰力小，流量大、無外漏和方便可靠、防火防爆的優點。

進口氣動隔膜閥的安裝使用說明

氣動隔膜閥想對比手動隔膜閥，增加了氣動執行器和其它的電磁閥，限位開關等附件，在安裝和使用中相對于手動隔膜閥復雜得多，一些的進口隔膜閥品牌，都有說明書，比如美國威盾VTON的進口氣動隔膜閥，隨貨都帶有使用說明書，但很多用戶經常弄丟，那么，本文就再詳細介紹下；

1. 進口氣動隔膜閥必須放在干燥通風的室內，溫度宜在0°C~35°C之間；相對濕度為50~80%之間，以防襯里件老化而影響使用壽命。

The valvemust be placed in dry and ventilated room, the temperature should be at 0 ° C ~ 35 ° C between; relative humidity of 50 to 80%, and prevent aging of lining pieces of life.

2. 口氣動隔膜閥應避免與液體燃料、油料或其它易燃物品接觸。

Should be avoided withliquid fuel, oil or other flammable materials contact.

3. 進口氣動隔膜閥在存放期間或使用期間,應逆時針旋轉手輪,使閥門處于微啟狀態,避免使隔膜因長期受壓而失去彈性.

During storageor use during the hａnd wheel should rotate counter-clockwise, so that the valve is inching state, to avoid the divide and lose their elasticity due to prolonged pressure

4. 安裝前,應仔細核對管路使用條件是否與進口氣動隔膜閥規定的適用范圍相符;避免因選用不當而造成不必要的損失。

Before installation,check carefully whether the conditions of pipe to use the provisions of this scope in line valve; to avoid the improper selection of unnecessary losses

4. 安裝過程中，應將閥體內腔清洗干凈,避免污垢卡阻或損傷密封部件;并檢查連接部位的連接螺栓是否均勻緊固。

The installation process, you should wash the body cavity to prevent dirt jamming or damage the sealing components; and check the connection parts of the connection bolts are evenly tightened.

5. 運行中必須經常檢查與介質接觸的密封部位及其它易損零件;并按實際使用情況，定期更換易損部件。

Operation, you must always check the seal area contact with the media and other vulnerable parts; according to actual usage, regular replacement of wearing parts

6. 當需要更換管夾時,應注意切勿將隔膜擰得過緊或過松。

When the need to replace tube clip，Diaphragm should not be too tight or too loose screw

7. 在檢修中，當必須打開氣缸與氣缸蓋時，應首先排除氣缸內的氣源壓力，然后方可拆除連接螺栓。

In the repair, when to open the cylinder and cylinder head, they should first rule out the air pressure inside the cylinder, then remove bolts

8. 進口氣動隔膜閥如用于間斷性運行的管路上，則在停止使用時，應清洗與介質接觸部位，以延長閥門使用壽命。

If thevalve for the intermittent operation of the pipeline, when not in use, the contact area should be cleaned with the medium to longer valve life

9. 在手動操作閥門時，不得借助于輔助杠桿使閥門啟閉，以免扭矩過大而損傷驅動零件或密封部位。

In the manualoperation of the valve may not open and close the valve by means of auxiliary lever so as to avoid excessive torque while the injury-driven part or sealing parts

14．凡經檢修后的閥門，應按有關規定進行密封性能試驗，合格后方能安裝使用，并作好記錄以供查考。

Afterall, after the valve repair, according to relevant provisions of the sealing performance test, qualified before installation and make records for the traced

15.氣動閥門均有手操部件，當氣源發生故障而中斷時，且閥門急需啟、閉的緊急狀態下，可順時針旋轉手輪使閥門關閉，反之則開啟。

Pneumatic valves are the terminal parts, when the gas supply is interrupted failure, and valves need opened, closed under the state of emergency, clockwise handwheel valve closes, conversely open.

16．當需恢復氣動操作時，必須首先旋轉手輪至氣缸內留有行程間隙后，方可輸入操作氣源。

When to recover pneumatic operation, must first rotation handwheel to leave in the air gap and then travel after maximum input operating air supply
