德國《LOCKE》洛克進口防爆電動球閥(Explosion proof electric ball valve)防爆等級為dⅡBT4、防護等級為IP67、帶現(xiàn)場控制裝置。

防爆電動球閥主要特點為：不通電時，扳動離合器手柄可進行手動操作。通電時，離合器自動復位。流向可任意，可調(diào)范圍廣，能用于高壓和大口徑場合，控制高粘度，帶有纖維和細顆粒的介質(zhì)。

The explosion-proof proof electric ball valve imported by Locke in Germany has the explosion-proof grade of D Ⅱ BT4, the protection grade of IP67 and the field control device.

The main features of explosion-proof electric ball valve are: when the power is off, the clutch handle can be manually operated. When energized, the clutch resets automatically. Flow direction can be arbitrary, adjustable range, can be used in high-pressure and large caliber occasions, control high viscosity, with fiber and fine particles of the medium.

三、進口防爆電動球閥優(yōu)點：

1、由于聚四氟乙烯等材料具有良好的自潤滑性，與球體的摩擦損失小，幫球閥的使用壽命長。

2、下裝式閥桿和閥桿頭部凸階防止閥桿噴出，如火災造成閥桿封破壞，凸階與閥體間還可形成金屬接觸，確保閥桿密封。

3、閥桿密封可靠，由于閥桿只作旋轉(zhuǎn)運動而不做升降運動，閥桿的填料密封不易破壞，且密封能力隨著介質(zhì)的壓力增大而增大。

4、閥座密封性能好，采用聚四氟乙烯等材料制成的密封圈，結(jié)構(gòu)易于密封，而且球閥的閥封能力隨著介質(zhì)壓力的增大而增大。

5、電動裝置殼體采用國外硬質(zhì)鋁合金，經(jīng)陽極氧化處理和聚酯粉末涂層，耐腐蝕性強，防護等級IP67，NEMA4和6，并有IP68和防爆型供選擇

1. Because PTFE and other materials have good self-lubricating property, the friction loss with the ball is small, and the service life of the ball valve is long.

2. The bottom mounted valve rod and the convex step at the head of the valve rod prevent the valve rod from ejecting. If the fire causes damage to the valve rod seal, metal contact can be formed between the convex step and the valve body to ensure the valve rod seal.

3. The valve rod seal is reliable. Because the valve rod only rotates without lifting, the packing seal of the valve rod is not easy to be damaged, and the sealing capacity increases with the increase of the medium pressure.

4. The sealing performance of the valve seat is good. The sealing ring made of polytetrafluoroethylene and other materials is easy to seal, and the sealing capacity of the ball valve increases with the increase of the medium pressure.

5. The shell of electric device is made of foreign hard aluminum alloy, which is anodized and coated with polyester powder. It has strong corrosion resistance, protection grade of IP67, NEMA 4 and 6, and IP68 and explosion-proof type are available for selection

四、進口防爆電動球閥安裝說明：

（1）取掉法蘭端兩邊的保護蓋，在閥完全打開的狀態(tài)下進行沖洗清潔。

（2）安裝前應按規(guī)定的信號（電動或氣動）進行整機測試（防止因運輸產(chǎn)生振動影響使用性能），合格后方可上線安裝（接線按電動執(zhí)行機構(gòu)線路圖）。

（3）準備與管道連接前，須沖洗和清除干凈管道中殘存的雜質(zhì)（這些物質(zhì)可能會損壞閥座和球）。

（4）在安裝期間，請不要用閥的執(zhí)行機構(gòu)部分作為起重的吊裝點，以避免損壞執(zhí)行機構(gòu)及附件。

（5）本類閥應安裝在管道的水平方向或垂直方向。

（6）安裝點附近的管道不可有低垂或者承受外力的現(xiàn)象，可以用管道支架或者支撐物來消除管線的偏離。

（7）與管道連接后，請用規(guī)定的扭矩交叉鎖緊法蘭連接螺栓。

(1) Remove the protective covers on both sides of the flange end, and wash and clean when the valve is fully open.

(2) Before installation, the whole machine shall be tested according to the specified signal (electric or pneumatic) (to prevent the vibration caused by transportation from affecting the use performance), and it can be installed online only after it is qualified (the wiring shall be in accordance with the circuit diagram of electric actuator).

(3) Before preparing to connect with the pipe, the residual impurities in the pipe must be washed and removed (these substances may damage the valve seat and ball).

(4) During the installation, please do not use the actuator part of the valve as the lifting point to avoid damaging the actuator and accessories.

(5) This type of valve shall be installed in the horizontal or vertical direction of the pipeline.

(6) The pipeline near the installation point shall not be sagged or bear external force, and the pipeline support or support can be used to eliminate the deviation of the pipeline.

(7) After connecting with the pipeline, please cross lock the flange connecting bolts with the specified torque.
