More professional and more affordable and more convenient and more perfect locking resilient seated gate valve

7 resilient seated gate valve is also called the lift rod valve. Often movements are trapezoidal threaded rod, through the guide slot valve and the valve on top of the nut, and the rotary motion into linear motion, which is the operating torque thrust into action. Open the valve, when the gate valve lift height equal to diameter of 1: 1 times, the fluid channel is completely smooth, but at run time, this position can not be monitored. Actual use, is the apex of stem as a sign that the fixed position, as its fully open position. Temperature appears to consider locking phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as the location of a fully open valve. Therefore, the fully open position of the valve, according to damper position (ie, travel "to determine resilient seated gate valve main technical parameters: Nominal pressure: 1.0 ~ 2.5MPa Nominal by: 50 ~ 600mm Working temperature: 0 ~ 80 ℃ Applicable Medium: water, oil, gas and other flange standards: GB / T17241.6 GB9113 test standards: GB13927 AP1598 main external and connecting dimensions nominal diameter DN 50 65 80 100 125 150 200 250 300 350 400 450 500 600 800 L 178 190 203 229 254 267 292 330 356 381 406 457 457 508 660 H 240 260 265 310 370 420 500 610 670 820 860 890 1050 1210 1310 Nominal ≤1.6MPA major parts list Transmission Manual For medium water, steam, oil Suitable temperature ≤80 Celsius Z45X soft seal valve consists of six parts 1. 2. Thrust bearing three "O" - ring 3. The inner and outer precision machined stainless steel stem and the latest high-performance rubber coating curing technology 5. overall flat valve Block 6. The non-toxic epoxy resin coating structure and characteristics 1. The overall package of plastic spool, spool of ductile iron skeleton, inside and outside the high-performance vulcanized rubber and the latest technology for the overall coating, tight fitting solid, with excellent elastic sealing, leak reaches zero. 2. Adopt three "O" - ring design, seal tightly, significantly reducing Friction resistance and environmental health, there is also pressure off the water to replace the "O" type apron features 3. corrosion, internal and external surface of the body with epoxy coating, inner parts are made of stainless steel and copper alloys prevent rust and corrosion fluid can be directly used for domestic water and pharmaceutical industries.
