Glasses valve is plug-in boards valve, it mainly includes a box structure of the body, the body clamping driving mechanism and disc components and adjoining the valve plate movement organization, its body by former valve body, after the valve body and in the valve body composition, in body and after the body between disc components, fittings in the body of the valve body corresponding surface with former with corrugated flexible ware, this valve USES is unidirectional synchronous compaction way, its start torque is small, and self-locking of reliable seating performance, but also is equipped with the circulating cooling water chamber, make its improved valve applicable temperature.

Suitable for blast furnace gas pipeline, gas isolating valve use. Glasses valve opening and closing the leak, applicable to have installed outside gas pipes. The valve open through the conversion of plug-in boards through-hole with closure position to achieve, plug-in boards conversion must in the seal loosen, order action. Adopt soft rubber seal.
Glasses valve with the vertical and horizontal installation installed two forms.
Glasses valve driving devices:
Glasses valve driving devices is to use the power on-off needle valve plus type of device. Use drive device is designed to make the valve operation is labor-saving convenient, quick and reliable, or the realization of automatic control and remote control. Valve actuation device to the basic requirement is: the torque or thrust can satisfy the need, to open or close the valve stroke and the torque control accuracy and dynamic, we choose the suitable the site condition, on-off movement.ball conform to control requirements, the device itself light and small.
Drive mode: manual, pneumatic, electric hydraulic, all user requirements can be configured. Glasses valve driving devices on the output shaft movement way is divided into many rotary, part of rotary and linear reciprocating 3 kinds. Many rotary namely much circle of rotary, applicable to the valve stem or stem nut need to fully open or turn much circle, such as gate valves fitted, stop valve, output torque values of the series is commonly 40 ~ 10000 cow meters (thrust for 20 ~ 11 thousand cattle). Part of rotary applies to stem within a circle in the rotation can fully open or seated valves, such as ball valves, butterfly valve, the output torque of series general for 125 ~ 125,000 cow meters. Linear reciprocating applies to stem only do straight reciprocating motion can fully open or seated valve as solenoid valves.
Glasses valve driving devices according to power source can be divided into manual device, gear transmission device, a pneumatic device and electric device, hydraulic device, gas-liquid interlock, electro-hydraulic interlock, etc. The most primitive and simplest valve actuation device is handwheel and handles. Along with the needle valve type of large-scale and production process automation of all kinds of needle valve actuation device type of need more and more. Needle valve actuation device type in industrial production automation occupies an important position.
