PEEK Compressor Valves for Smoother Breathing

What is Valve ?

Piston compressor valve is used for suction and exhaust with its working principle is to rely on the piston up and down to start generating suction and exhaust, the piston down is suction, up is the exhaust suction is the outside of the gas sucked into the piston, by the piston to the compression and then discharged into the cylinder, such a return back and forth coupled with high-speed operation to generate pressure.

The valve is placed in the position of the upper bearing exhaust port, its function is to close the refrigerant inside the cylinder, the refrigerant is compressed inside the cylinder, when the pressure of compression reaches a certain value, the valve is pressed open, and the compressed refrigerant is discharged from the exhaust port of the upper bearing. Its action is determined by the pressure inside the cylinder.

What is PEEK valve ?

For hydraulic and ball valves with special sealing requirements, Plastics has developed carbon-fiber-reinforced PEEK seats as an alternative to stainless steel for the manufacture of ball valve seats and cones.The high-performance polymer of PEEK can be processed using standard injection molding equipment to produce seats and cones with high dimensional stability at no additional cost. Another important advantage of injection molding is the freedom of design, using fluid simulation software (CTD) to reduce the pressure loss of new seats and cones by about 20% at higher flow rates. At the same time, the carbon fiber orientation of injection-molded parts can be optimized for higher mechanical strength and does not require time-consuming post-processing operations.

Advantages of PEEK valve ?

As sealing improves, the power consumption of the compressor decreases in tandem with the temperature rise, and the energy consumption of a compressor with PEEK valve blades can be reduced by 5-10% compared to metal valve blades.

The long-term use temperature of PEEK is 250℃, and the normal working temperature of the valve sheet can be more than 200℃. The differential pressure of the valve plate can reach more than 15MPa.

PEEK valve piece density is small, the same volume and weight is light, in the reciprocating compressor working condition, the impact force is reduced, the resulting fatigue damage is reduced, the valve life is extended, the service life of up to 6,000 hours. Strong corrosion resistance, can absorb part of the impact energy to reduce noise.

PEEK valve sheet in the working temperature, the sealing surface has a self-adjusting function, can be automatically completed within 24 hours with the contact surface shape of the fine-tuning, so that the sealing effect is better, the compressor to achieve high compression efficiency in a short period of time.

PEEK valve plate toughness, not easy to break, even if the valve plate breaks into the cylinder will not cause damage to the cylinder or produce sparks.

PEEK oxygen index is high, in the flammable gas as the medium of the compressor working conditions, PEEK valve plate has a higher degree of safety.

PEEK valve discs are unaffected by water and high pressure water vapor.

Temperature of PEEK valve

PEEK valve sheet has more high temperature resistance, corrosion resistance, self-lubrication, wear resistance, creep resistance, fatigue resistance and some other special properties. High temperature resistance PEEK has a high glass transition temperature (Tg = 143 ° C) and melting point (Tm = 334 ° C), its load heat distortion temperature of up to 316 ° C, the long-term use of the temperature of 260 ° C, the instantaneous use of up to 300 ° C temperature.

The application of PEEK valve ?

PEEK material is an ideal material for natural gas compressor valve plates, which can improve the efficiency and reliability of natural gas compressors and reduce maintenance costs. Therefore, it is widely used in aerospace, automotive, electronics, medical and other fields.PEEK processing part

The high performance of the material makes it the preferred material for natural gas compressor valves, as the working environment of natural gas compressors is very harsh, the valve material needs to have high wear resistance, high corrosion resistance, high heat resistance and other properties to ensure the long-term stable operation of the valve. the high temperature resistance of PEEK material makes it possible to maintain the mechanical properties of the material in a high temperature and high pressure environment, and at the same time, its high strength and stiffness PEEK material is able to withstand high frequency switching operations. Compared to conventional materials, valve discs made of PEEK have better wear resistance, higher stiffness and strength, and better corrosion resistance. In addition, PEEK material also has good self-lubricating properties, can reduce the friction between the valve plate and the cylinder, thus reducing the wear and energy consumption of the valve plate.Peek fabrication component

PEEK valve plate density, modulus of elasticity, impact reduction, resulting in fatigue damage and subsequently reduce the valve life greatly extended, under normal circumstances its life is much better than metal valve plate, and good sealing performance, air leakage is reduced, the valve plate run together with good performance.

Compared with the metal valve plate, PEEK valve plate flow characteristics better than similar metal valve plate, valve gap between the airflow friction caused by the reduction of energy loss, valve energy consumption can be reduced up to 5% -10%, but also resistant to solid particles and droplets of the impact of the valve plate fracture crack propagation speed is slower, even if the valve plate breaks into the cylinder after the drop will not cause damage to the cylinder, and low noise during operation, good self-lubrication, can be used for oil lubrication and oil-free lubrication of machinery, and can be used for oil lubrication. Low noise during operation, good self-lubrication, can be used in oil lubrication and oil-free lubrication machinery.POLYETHERETHERKETONE fabrication Parts
