GB 600 Gate Valve

The national standard DN600 Square Cap Gate Valve is refers to closes the piece (the gate plate) along the Path Center line the Vertical Direction Movement Valve. National Standard DN600 Square Cap Gate Valve in the pipeline can only be fully open and fully closed off, can not be used for regulation and throttling. DN600 Square Cap Gate Valve is a kind of valve which is widely used. It is usually used for cutting device with diameter DN ≥50mm, and sometimes for cutting device with small diameter DN600 square cap gate valve. The opening and closing part of DN600 Square Cap Gate Valve is the gate plate, the Movement Direction of the gate plate is perpendicular to the flow direction, the DN600 square cap gate valve can only be fully opened and fully closed, can not be adjusted and throttled. DN600 Square Cap Gate Valve is a kind of valve which is widely used. It is usually used for cutting devices with diameter DN ≥50mm, and sometimes for cutting devices with small diameter DN600 square cap gate valve has two sealing surfaces, the wedge-shaped and wedge-shaped angles of the two sealing surfaces of the commonly used pattern gate valves vary with the valve parameters, usually 50, and 2 ° 52'when the medium temperature is not high. The gate plate of DN600 square cap gate valve can be made as a whole, which is called rigid gate. It can also be made into gate plate which can produce slight deformation to improve its workability and make up for the deviation of sealing surface angle in the process, this type of gate is called an elastic gate. National Standard DN600 Square Cap Gate Valve is the main control equipment for the flow or transportation of powder material, crystal material, granular material and small piece of material, widely used in metallurgy, mining, building materials, grain, chemical and other industries to control flow changes or rapid cut-off. GB DN600 Square Cap Gate Valve refers to the type of cast steel GB DN600 Square Cap Gate Valve. According to the sealing surface configuration can be divided into wedge-type GB DN600 square cap gate valve and parallel GB DN600 square cap gate valve, dN600 square cap wedge-type National Standard Gate Valve can be divided into: Single Gate, Double Gate and Elastic Gate; parallel gate DN600 Square Cap Gate Valve can be divided into single gate and double gate. According to the screw position of valve stem, can be divided into stem DN600 square cap gate valve and dark stem DN600 square cap gate valve. When DN600 Square Cap Gate Valve is closed, the sealing surface can be sealed only by medium pressure, that is, the sealing surface of the gate plate is pressed to the valve seat on the other side by medium pressure to ensure the sealing surface, which is self-sealing. Most national standard DN600 Square Cap Gate Valve is the use of forced sealing, that is, when the valve closed, to rely on external force to press the gate to the valve seat, to ensure the sealing surface of the seal. GB DN600 square cap gate valve with the stem of the gate plate for linear motion, called lifting Rod DN600 Square Cap Gate Valve (is also known as stem DN600 square cap gate valve) . Usually on the lifting Rod, there are trapezoidal threads, through the top of the valve nut and the valve body on the guide Groove, the Rotary Movement into linear movement, that is, the operation of Torque into operation thrust. When the valve is opened, the flow path is fully open when the gate lift is 1:1 of the valve size, but this position can not be monitored during operation. In actual use, the apex of the stem is used as a symbol, that is, the position of the open fixed, as its full open position. In order to take into account the temperature lock phenomenon, usually in the open to the top position, and then back 1/2-1 turns, as a full-open Valve position. Therefore, the full open position of the valve, press the gate position (I. E. Stroke) to determine. Some national standard DN600 square cap gate valve, stem nut set on the gate, hand wheel rotation drive stem rotation, and make gate plate lift, this valve is called rotating rod DN600 Square Cap Gate Valve or dark rod DN600 Square Cap Gate Valve./* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
