Introduction and characteristics of the soft sealing gate valve of the Ming bar:

　　The elastic seat sealing gate valve is called the lift rod gate valve (also known as the gate valve). Usually in the lifting rod with trapezoidal thread, through the soft sealing gate valve at the top of the nut and the valve guide groove, rotary motion variable into linear motion, that is, the operating torque, thrust into action. When the valve is opened, when the gate valve to increase the height of the 1:1 times the diameter of the fluid, the fluid channel is completely smooth, but at run time, this position is unable to monitor. When the actual use, is the stem of the apex as a symbol, that is, open position, as it is the full open position. In order to consider temperature changes occur locked phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as a fully open valve position. Therefore, the valve fully open position, according to the location of the gate (that is, stroke, to determine the.

　　The rod spring valve (RRHX/Z41X-16) valve stem nut on the valve cover or nails, open and close the gate, with a rotating stem nut to achieve the hair dry lift. This structure of the valve stem lubrication is good, open and close degree is obvious. It is a gate opening and closing parts, perpendicular to the direction of movement and direction of flow of the gate, gate valve can be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surfaces, the most commonly used mode gate valve of the two seals. Soft sealing gate valve in the pipeline in general should be horizontal installation. My company production of valve with high quality nodular cast iron, after processing, spray and multi-channel procedures, excellent quality and good reputation.

Technical parameters of elastic seat sealing gate valve:

　　Working pressure: 1.6Mpa, 2.5Mpa, 1.0Mpa, working temperature: 0-80.

Parts material:

　　Three "O" - shaped ring can be a substantial reduction in the phenomenon of leakage, and in the case of pressure and water to replace. Thrust bearings to reduce friction resistance to reduce operating torque. Precision machined valve stem, can reduce operating torque. The use of the whole rubber full cover design is connected with the internal and external use, which can avoid the loss of long-term use. Body bottom no groove, not easy to cause debris deposition. Body and outside the use of non-toxic epoxy resin coating, enhance the ability to resist corruption, improve the quality of water.
