Range Top Burner Valve noise sources

There are three main range valve noise sources:
    (1) itself vibration noise. Medium flows through the burner valve spool will produce erosion, lateral movement of the spool produce unstable even resonate with the device. Due to the use of Range Top Burner Valve vibration is inevitable, so this kind of noise generation is also inevitable. Note that when you try to install the valve upright on a horizontal pipe installed to reduce noise generated due to the spool instability, usually this kind of noise is very small, resulting in little impact.
    (2) Aerodynamic noise. When contracted flow medium flows through the burner valve section, the flow cross section due to contraction of the flow path blocking sudden changes occur turbulence, while the medium flow rate is changed, the mechanical energy is partially converted liquid noise acoustic energy generated by known aerodynamic Science noise. Because fluid Gas Burner Safety Valve when pressure is inevitable, so the aerodynamic noise can not be completely eliminated. Usually this type of noise level is small, resulting in little impact.
    (3) Hydrodynamic Noise. Fluid control valve in the rapid formation of blocking flow velocity. Blocking flow refers to the incompressible or compressible fluid flows through the stove burner valve when the maximum achievable flow state. At a fixed inlet conditions, when the valve before the pressure kept constant while gradually reducing the pressure after the valve, the flow through the flow Stove Top Burner Valve increases to a maximum limit, and then continue after the pressure reducing valve, the flow rate will not increase, the limit that is blocking traffic flow. Blocking the flow of liquid can easily cause flash cavitation, accompanied by strong noise generation, this noise is usually up to about 100dB, resulting in a large impact.

Full-featured ultra-regulating valve and control valve comparative advantage

A total of nine regulating valve function, full-featured ultra-light valve nine features are excellent, so called full-function valve.

Good regulation

Regulatory function is one of the main functions of the control valve, the performance of ① flow characteristics; ② adjustable ratio R; ③ small opening performance; ④ flow coefficient; ⑤ adjust the speed. Full-featured ultra-light valve R = 100, so that the small opening adjustment is good; Kv value is large, is 2 to 3 times a single seat Safety Valve Burner Valve, the sleeve valve.

Cut-off function Good

Cut-off function to reflect the intrinsic quality of the valve. Linear actuator valve standard leak rate is usually 10 to 10; full-featured ultra-light valve standard leak rate of 10, compared with single-seat valves, valve sleeve 100 to 1000 times higher.

To overcome the large pressure difference

Overcome the pressure off function is to ensure the premise, and the cut-off function are inseparable. Seat valve allows pressure large, but a large leak; single seat valve leak is small, but allowing the pressure is small. Full-featured ultra-light gas safety burner valve a better solution pressure large, leak also requested a small problem, which allows the pressure up to PN value.

Corrosion strong function

Function ensures that the valve can resist corrosion corrosive media, erosion, cavitation and other damage and prolong life. Full-featured ultra-light valve using a corrosion-resistant material and erosion prevention measures, has good corrosion features.

Attempts to prevent the function is good

Attempts to prevent function well in order to effectively ensure that the valve is not clean medium occasions in normal operation. Follow the principles of fluid mechanics developed and designed a full-featured ultra-light valve, the flow path has a simple, less dead zone whirlpool, medium-through is not easy to settle, and good self-cleaning function, has become a high viscosity, suspension, pulp, concentrated slurry, containing The preferred medium is not clean product particles occasions applications.

High strength

Pressure function is to ensure the safety valve. Full-featured ultra-light valve body structure as a single piece integrated structure, improve the structural integrity of the pressure boundary, improved compressive strength. High pressure forged structure, to further improve the compressive strength of the body, the compressive strength of up to 32MPa or more.

Temperature function is good

Temperature function is to ensure the valve adapted to different temperatures. Full-featured ultra-light valve using rigid-flexible hard seal resolve core, seat package expansion card problems caused by high temperatures; using high temperature resistant filler Stove Top Burner Valve stem at a high temperature to ensure the reliability of the seal.

Good appearance and light weight

Appearance and weight function reflects the valve miniaturization, weight reduction, instrumentation features. Full-featured ultra-light valve with integrated body structure optimized design and appearance, and with a simple and reliable way directly connected to the actuator is connected, compact structure, small size, light weight, good appearance. Full-featured ultra-light valve with traditional leading products single-seat, two-seat, sleeve valve compared to its weight decreased by 60-80%, 40-60% lighter than the CV3000 and fine small valve. To DN100 electric valve, for example, the sleeve valve weighs about 150Kg, and full-featured ultra-light valve weighs only 40Kg (electronic), light 73%.
