Eyeglass valve use and drivePosted by uuuseff on November 17th, 2019 The eyeglass valve is also a plug-in valve, which mainly comprises a box-shaped valve body, a valve body clamping drive mechanism and a valve plate assembly and a valve plate movement mechanism connected with the valve body, wherein the valve body is composed of a front valve body, a rear valve body And in the valve body composition, the valve body and the valve body assembly between the valve body, the valve body and the front surface of the valve body is provided with a bellows expansion device, the valve is used in one-way simultaneous compression, the Starting torque is small, and the self-locking is good, reliable sealing performance, but also has a circulating cooling water chamber, which increases the temperature of the valve. For blast furnace gas pipeline, used for gas cut off valve. Eye valve opening and closing there is leakage, suitable for installation in outdoor gas pipeline. The opening of the valve is realized by changing the position of the through hole and the blind plate on the insertion plate, and the conversion of the insertion plate needs to be carried out under the condition that the sealing is released, and the sequence action is performed. Soft rubber seal. Glasses have vertical installation and horizontal installation of two forms. Glasses valve drive: glasses valve drive device is the use of external power needle valve opening and closing device. The purpose of using the drive is to make the operation of the valve easy and labor-saving, fast and reliable, or to achieve automatic control and remote control. The basic requirements of the valve drive are: Torque or thrust can meet the valve opening and closing needs, the stroke and torque control is accurate and reliable, the power of choice for the scene, opening and closing action in line with control requirements, the device itself is light and small. Drive mode: Manual, hydraulic, electro-hydraulic, can be configured according to user requirements. Eye valve actuator driven by the output shaft is divided into multi-rotary type, part of rotary and linear reciprocating 3. Multi-turn or multi-turn rotary type, apply to the valve stem or stem nut need to turn multiple laps to fully open or close the valve, such as gate valve, globe valve, the output torque value of the series is generally 40 to 10000 Nm Thrust is 20 ~ 1100 kN). Part of the rotary valve for the revolution in a circle can be fully open or close the valve, such as ball valve, butterfly valve, the output torque of the series is generally 125 ~ 125000 Nm. Linear reciprocating applies to the valve stem only linear reciprocating motion can be fully open or close the valve, such as solenoid valve. Glasses valve drive by power source can be divided into manual devices, gear drives, pneumatic devices, electric devices, hydraulic devices, gas-liquid linkage, electro-hydraulic linkage. The most primitive and simple valve drive is the hand wheel, handle. With the needle valve of the large-scale and automated production process, a variety of needle valve drive device needs more and more. Needle valve drive in industrial automation plays an important role. Checker plate includes various kinds of tread.Normally there are big five bar,small five bar,two bar,stucco,,pointer,diamond and so on.
