Paper mill commonly used V regulating pneumatic valve has these characteristics

Ordinary type O regulating pneumatic valve is usually applied in the fluid control using clean, like water, oil, etc. , its sealing is good, but does not apply to contain tiny particles or turbid liquid medium containing fiber is used, this kind of circumstance should choose V pneumatic valve adjustment, because of its structure characteristics, make it suitable for papermaking, chemical industry, metallurgy and other industrial enterprises contain fiber or small solid particles in suspension medium on relevant process parameters control, more suitable for pulping and papermaking pulp black liquor, white water, in the process of production, such as white liquor suspended particles of fluid and thick, turbid fluid automatically adjust slurry. Here a brief introduction of v-shaped adjustment for you a few characteristics of pneumatic valve.







electric V pneumatic valve adjustment


the main characteristics of v-type regulating pneumatic valve:


1, v-type regulating pneumatic valve without the integral pneumatic pipe body, so is not affected by pipeline or bolt stress, and because no pipe pneumatic valve body, so the pressure hull would not be affected by pressure 'mutation';
2, pneumatic valve, pneumatic valve core has a 'V', even if in the case of small flow rate or high viscosity media, can also be within the scope of the whole range, to ensure the control accuracy;
3, leak proof and durable pneumatic seat at the outer diameter of PTFE lined with stainless steel inner core cup or type O sealing ring, pneumatic seat made from cross section larger cobalt tungsten carbide, by a corrugated alloy spring to further enhance the structure of the pneumatic valve seat;
4, when the pneumatic valve closing, v-notch with pneumatic seat wedge shearing action, and both have the function of self-cleaning and can prevent the core card dead, especially suitable for high viscosity, suspension, such as pulp is not clean, fiber media.

the daily maintenance of v-type regulating pneumatic valve


1, always adhere to the 'V' pneumatic valve parts of the activity and external cleaning, maintenance of pneumatic valves paint in good condition. Dust and oily be soiled on pneumatic valves should be punctual to clear.
2, pneumatic valve, trapezoidal screw, nut and meshing area and activity area, should always keep smooth, avoid rust and stuck.
3, pneumatic valve body is in good condition, pneumatic valve shall be complete, intact, screw, nut should prevent loose, tighten the packing gland should be tightened, should be timely replacement, supplement the missing parts. In addition, the pneumatic valve tapping, place heavy objects, or not allowed to stand, to avoid damage to V pneumatic valve.
