The open type electricgate valve is an open design structure with light weight and easymaintenance (sealing rubber ring replacement, electro-hydraulic devicemaintenance inspection, replacement, partial maintenance of valve are all doneexternally, do not affect normal operation of valve). Valve movement processand switching state is intuitively good. Open and close status after operation isvery convenient to check and has irreplaceable advantage compared with enclosedtype. The disadvantage is that thereare a small number of gas leakage and operator should pay attention toprotection when opening and closing.
1. The valve body of open type gate valveadopts frame type structure,
2. Sealing pairs uses stainless steel andrubber sealing ring, seal is reliable with long service life.
3, Open type gatevalve adopts spring clamping mechanism, which has good synchronicity.
4. Open type gate valve has sealing ring installedon the valve plate for easy replacement.
5. The metallurgical valve is added with water coolingmechanism, and the highest temperature can be up to 450 â, which is especially suitable for dry dedusting system.
6, with a variety of drive options,hydraulic, electric can achieve computer program control
The open type electric gate valve absorbsthe advantages of the floating valve plate from foreign gate valves. The compression mechanism adopts the multi-purpose gear ring, gear,trapezoidal thread, lever screw pair and synchronous bidirectional compression.The advantages of synchronous compression of left and right trapezoidal threadrods are: the starting torque is small, the lever screw pair self-searching isgood and seal is reliable, the plate movement adopts the pin tooth drivemechanism, ash not easy to accumulated and can satisfy usage under severworking conditions such more dust and worse lubrication.
The valve can be allocated on the opposite side with explosion-proofcontrol cabinet, realize field control and remote plc system connection controlwith distance of more than 10 meters.
According to the design of the open electric gate valve, severalother types of gate valve are developed; such asopen type pneumatic gate valve, enclosed type electric gate valve and so on, special requirementscan also customized. The enclosed type electric gate valve is reasonable and simple in structure, easy in manufacture, low incost and good in performance. The electric gate valve has theadvantages of no blocking, no leakage, convenient repair and maintenance, goodaccuracy of discharge quantity, high working efficiency, long service life, andso on.
