Main parts materials
Pneumatic sector blind valve
The pneumatic sector blind valve is mainly composed of left valve body, right valve body, screw pair, valve plate, sealing ring, lever, cylinder and other parts, and is composed of a base and a support column to form a rigid structure. The valve is equipped with a clamping and unclamping cylinder and a flipping cylinder. The clamping and unclamping cylinder drives the left and right valve bodies through a lever pair and screw screw pair to complete the unclamping and clamping actions. The flipping cylinder drives the valve plate to complete the unclamping and clamping actions. Switch action. The rubber sealing ring is embedded in the valve plate and has the characteristics of high temperature resistance, good sealing performance, easy replacement, and long service life. This valve can be controlled remotely by a single unit or by multiple units connected to the network. Under abnormal circumstances, it can also be operated manually by using the valve itself.
Hydraulic sector blind valve
The hydraulic sector blind valve is mainly composed of left valve body, right valve body, screw pair, flap, sealing ring, lever, hydraulic cylinder and other parts, and is composed of a base and a support column to form a rigid structure. The valve is equipped with a clamping cylinder and a flap cylinder. The clamping cylinder drives the left and right valve bodies through the lever pair and screw screw pair to complete the loosening and clamping actions. The flap cylinder drives the flap to complete the switching action. The rubber sealing ring is embedded in the flap and has the characteristics of high temperature resistance, good sealing performance, easy replacement, and long service life. This valve can be controlled remotely by a single unit or by multiple units connected to the network. Under abnormal conditions, it can also be operated manually by using the valve itself.
Electric sector blind valve
This valve consists of left and right valve bodies, sector valve plates, stainless steel bellows, electric drive device, electric clamping device and other components. The valve body adopts a three-point locking sector valve plate structure. The sealing part adopts stainless steel and rubber sealing ring, which has good sealing performance and long service life. The sealing ring is located on the valve plate, making it easy to replace the sealing ring during maintenance. Electric operation, stable operation, flexible starting and reliable action. The clamping mechanism uses a screw nut pair for clamping, which has good self-locking properties. The electric fan-shaped blind plate valve is equipped with a stainless steel bellows, which has the characteristics of strong flexibility and long service life. It is widely used in the management of gas and toxic gas media in industrial and mining enterprises, environmental protection and other industries as a reliable cutting device.
Electric push rod sector blind valve
The electric push rod sector blind valve is mainly composed of left valve body, right valve body, screw pair, flap, sealing ring, lever, explosion-proof electric push rod and other parts, and is composed of a base and a support column to form a rigid structure. The valve body is equipped with a clamping push rod and a flip plate push rod. The clamping push rod drives the left and right valve bodies through a lever pair and a screw screw pair to complete the loosening and clamping actions. The flip push rod drives the flip plate to complete the switch. action. The rubber sealing ring is embedded in the flap and has the characteristics of high temperature resistance, good sealing performance, easy replacement, and long service life. This valve can be controlled remotely by a single unit or by multiple units connected to the network. Under abnormal conditions, it can also be operated manually by using the valve itself.
Open electric blind valve
This valve has an open design structure, which is light in weight, easy to maintain (replacement of sealing rubber ring, inspection and replacement of electric device, and partial maintenance of the valve are all external and will not affect the normal operation of the valve). The movement process and switching status of the valve are intuitive. Well, it is very convenient to check the completion status after opening and closing. It has the irreplaceable advantage of sealing. The disadvantage is that a small amount of gas leaks when opening and closing. This valve has absorbed the advanced technology of the floating valve plate of foreign plug-in valves in the design and production, which increases the sealing reliability, and the transverse movement is light and reliable. The valve plate moves using a pin-tooth transmission mechanism, which is not prone to dust accumulation and is suitable for use in situations with a lot of dust, poor lubrication conditions, and harsh working environments. The clamping adopts the form of multi-point synchronous clamping in one device, which has good synchronization and high reliability. This valve can be equipped with an explosion-proof control cabinet on the ground to implement on-site control and remote connection control with the PLC system. The setting distance is more than 10 meters.
Fully enclosed electric blind valve
The fully open and closed electric gate valve is suitable for dry metallurgical blast furnace gas systems. It plays a reliable and absolute cutting role in the gas pipeline. It has a compact structure, safe and reliable operation, and good control performance. There is no gas leakage during the opening and closing process of the valve. polluted environment. This series of closed electric plug-in valves is mainly composed of main valve body, auxiliary valve box, valve plate, rubber sealing ring, screw screw pair clamping and releasing mechanism, plate moving mechanism, telescopic device, etc. The base and the box connecting flange form a rigid structure. The valve plate moves using a pin-tooth transmission mechanism, which is not prone to dust accumulation and can be used in situations with a lot of dust, poor lubrication conditions, and harsh working environments. The clamping adopts the form of multi-point synchronous clamping in one device, which has good synchronization and high reliability. This valve can be equipped with an explosion-proof control cabinet on the ground to implement on-site control and remote connection control with the PLC system, with a setting distance of more than 10 meters.
