Goggle valve, also known as the Electric Sector Blind Plate Valve, is a pivotal component in industrial applications, offered by Henan Shangfa Valve Co. Ltd from China.

Electric sector blind plate valve consists of left valve body, right valve body, lead lever pair, valve plate, sealing ring, lever and electric clamping device, etc., and form a strong steel structure by the base and support columns

The valve has clamping and plate turning devices. The clamping device drives left valve body and right valve body to achieve loosening, clamping action through lead lever pair and screw pair and plate device drives valve plate to complete switch action.

Electric sector blind plate valve has rubber seal ring embedded on the valve plate which enjoys features of high temperature resistance, good sealing performance, convenient maintenance and long service life, etc.

This series also has worm gear operated sector blind plate valve, hydraulic sector blind plate valve and manual sector blind plate valve, etc., Special specifications needed by users can be customized

Structure drawing of electric sector blind plate valve. Electric sector blind plate valve can be controlled by single remote control, or by multi- network distance control
The valve can also be manually operated by body build-in device under normal conditions

The open type electric gate valve is an open design structure with light weight and easy maintenance (sealing rubber ring replacement, electro-hydraulic device maintenance inspection, replacement, partial maintenance of valve are all done externally, do not affect normal operation of valve). Valve movement process and switching state is intuitively good. Open and close status after operation is very convenient to check and has irreplaceable advantage compared with enclosed type. The disadvantage is that there are a small number of gas leakage and operator should pay attention to protection when opening and closing.

1. The valve body of open type gate valve adopts frame type structure,
2. Sealing pairs uses stainless steel and rubber sealing ring, seal is reliable with long service life.
3, Open type gate valve adopts spring clamping mechanism, which has good synchronicity.
4. Open type gate valve has sealing ring installed on the valve plate for easy replacement.
5. The metallurgical valve is added with water cooling mechanism, and the highest temperature can be up to 450 ?, 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 absorbs the 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 thread rods are: the starting torque is small, the lever screw pair self-searching is good and seal is reliable, the plate movement adopts the pin tooth drive mechanism, ash not easy to accumulated and can satisfy usage under sever working conditions such more dust and worse lubrication.

The valve can be allocated on the opposite side with explosion-proof control cabinet, realize field control and remote plc system connection control with distance of more than 10 meters.

According to the design of the open electric gate valve, several other types of gate valve are developed; such as open type pneumatic gate valve, enclosed type electric gate valve and so on, special requirements can also customized. The enclosed type electric gate valve is reasonable and simple in structure, easy in manufacture, low in cost and good in performance. The electric gate valve has the advantages of no blocking, no leakage, convenient repair and maintenance, good accuracy of discharge quantity, high working efficiency, long service life, and so on.

Enclosed type electric gate valve
The valve adopts an enclosed design structure, the valve body adopts a fully enclosed shell, the gas in the pipeline has no leakage during operation, which avoids pollution of the environment, has a better strength of resisting external force of the pipeline, and the electric device is externally installed and easy to maintain and inspect. The safety performance of personnel close operation is high

The valve design absorbs the advantages of floating plate of foreign gate valves, and the clamping and rotation mechanism adopts multi-point synchronous tightening mechanism, which has the advantages of good sealing performance, reliable operation, convenient maintenance, etc.

The enclosed electric gate valve can be widely used in the fields of metallurgy, chemical industry, food and so on, which need to be discharged quantitatively in modern industry. It has good popularization and application value and broad market prospect.
