PTFE mesh conveyor belt series

We select advanced imported loom,using high-quality imported glassfiber or Kevlar as basic weaving material, coated with excellent PTFE resin to make it into various PTFE mesh conveyor belts.

 


Features of PTFE conveyor belts:
1. High temperature resistance--It can continuously work under-140 to 260ºC, max resist high temperature up to 360ºC
2. Air permeability--It can avoid wasting heat and improve drying efficiency.
3. Chemical resistance--It can resist all most of chemical medicines.
4. Non-Sticky--It can easily remove all kinds of adhesives such as resin, paint and chemical medicines.
5. Good flex fatigue resistance--It has high tensile strength and excellent flex fatigue resistance. It's better for small wheels

 



Applications:
1.Drying machine for non-woven textile, textile printing, silk- printing and dyeing machine.
2.Shrinking machine for garment fabric, high-frequency and UV dryer.
3.Conveyor belt for hot-air dryer, various of food baking, quick-frozen machines.
4.Oiling machine for paper glazing and waxing, plant engineering.
5.Seperating sheet for hardboard production etc.



 




 

Globe Valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. Globe valves may be used for either isolation or throttling service, by installing the apporpriate disc: flat-seat disc for moderate throttling, cage for more severe throttling, and parabolic plug for linear flow control.

Globe valves are also classified by the body: regular staight pattern, Y pattern and angle pattern. Their various configuration allow them to be installed in a variety of piping configurations.

Globe Valve	Pressure Seal Globe Valve	Forged Steel Globe Valve

Globe valves are also supplied with three basic type of body-bonnet closures: bolted bonnet, welded bonnet and pressure seal bonnet. Bolted bonnet, the seal depends on the body-bonnet bolt preload to maintain sufficient compressive force, bolted bonnet is widely used for valves on various pressure ratings and sizes. Welded bonnet is mainly applied for small-size forged steel gate valves, suitable for applications requiring zero leakage on body-bonnet joint when carrying hazardous system fluids. Pressure seal bonnet is adopted for valves for high pressure service, typically in excess of 15 MPa (2250 psi). The body-bonnet joint seals improves as the internal pressure in the valve increases, compared to other constructions where the increase in internal pressure tends to create leaks in the body-bonnet joint.

Globe valves are supplied with flanged ends, butt weld ends, socket weld ends and screwed ends, and are constructed with various materials of cast carbon steel, stainless steel, alloy steels, and forged steels.

Various combinations of seating and stem materials are available to meet specific customer requirements.

The Cross-section of a Typical Cast Steel Globe Valve:

      1) Impactor handwheel provides higher torque through strking, and meet tighter shutoff for globe valve. This type of handwheel is supplied upon request.

2) Austenitic ductile iron stem nut provides resistance to wear and heat.

      3) Revolving rising stem with precision trapezoidal threads for long-lasting service.

4) Two piece self-aligning gland bushing and gland flange prevent stem damage.

      5) Spacer rings and double packing sets available upon request.

6) Machined Backseat designed to relieve back pressure on the stem packing when fully seated. Replacing stem packing under pressure is not recommended.

7) Conical Disc guided to assure alignment between disc and valve body. This design provides tigher shutoff with less closing torque, while spherical and flat seat surfaces are also available

8) Angle.and oblique Y type bodies are available.
