Flash condition noise stove top burner valve

    Blocking flow through the gas burner safety valve when a flash occurs, the bubble generated downstream adjustment Gas Burner Safety Valve will produce erosion by scouring the spool surface will smooth polished appearance, this
    From the mechanism of the gas burner safety valve to flash the (PVC <PV and P2 <PV) adjustment, the flash can not be eliminated, only to find ways to reduce the harm flashing on the stove valve, thereby reducing noise. Commonly used method is the region of the material to be washed surface hardening treatment, surface hardening treatment methods include three types:
    (1) The seat and the gas brass safety valve surface spraying, can be sprayed tungsten carbide, chromium carbide  to increase the hardness and other parts subject to erosion.
    (2) the surface of the stove valve seat and valve body surfacing treatment, usually by welding to increase the hardness of erosion site.
    (3) the valve seat and valve surface nitriding treatment to improve the surface hardness and wear resistance, corrosion resistance.
    By adjusting the burner valve surface hardening treatment can improve the hardness of the stove valve, the control valve to enhance the ability of anti-flash "erosion", the corresponding noise will be reduced 5 ~ 10dB. To further reduce noise, can be used with the methods used are: ① improve the pipe wall thickness or adding sound insulation layer in the pipe wall. Regulating burner valve the same diameter, which each additional level of pipe wall thickness, the measured value of the noise can be reduced by about 2dB; ② pipe plus sound-insulating layer to reduce the substance of pipe wall thickness also increases a measure of noise transmitted to the environment; ③ the Safety Valve Burner Valve after the installation of the online muffler, online muffler can absorb some of the sound energy, and after the formation of back pressure valve, which can effectively reduce the noise level of about 25dB.

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.

The selection of pneumatic control valve in chemical process

     Adjust the selector valve type and structure
     Depending on its stroke, pneumatic control valve can be divided into two different types, namely, the angle straight trip itinerary, according to the structure points, pneumatic control Range Top Burner Valve can be divided into the butterfly, angle valves, sleeve valves, ball valves, diaphragm valves, Globe valves and other types.
     Which, through single-seat control valve is the process of using the minimum amount of valve leakage, flow performance ideal, simple structure, can be used to leak demanding area, but its passage is relatively complex, which to some extent limit the scope of its use.
     Through safety gas aluminum valves is through single-seat control valve opposite a valve, there is no strict requirements for leakage, suitable for use in large-area working pressure at present, through engine regulation is our most extensive range of applications a control valve.
     Sleeve valve can be divided into two types, namely double sealed sleeve valve with single seal sleeve valve, the Gas Top Burner Valve sleeve has a good stability, low noise, easy accessibility, but its price is relatively high, and higher maintenance requirements Therefore, using the range are also some limitations.
     Diaphragm flow path is simple, its production and use is also high corrosion resistance PT-FE and PFA, it is suitable for application in alkali or acid environment, but relatively poor regulation.
