High pressure multi-stage pressure regulator gas burner valve trim

    This adjustment member has an inner Range Top Burner Valve pressure drop across the gas burner valve will be divided into several smaller pressure drop and ensure that each of the smaller voltage drop on PVC> PV effect, which can prevent the generation of cavitation. Since the multi-stage vacuum dispersed stream power, thereby reducing the sound conversion efficiency.
Limiting orifice has increased partial pressure of back pressure device to ensure that PVC gas burner valve on the> PV, prevent cavitation generation. Due to the increased back pressure device, so that the sound spectrum partially transferred, to achieve the purpose of noise reduction.
  Can not prevent the occurrence of cavitation, but reduce its harm.
The cavitation bubbles within the contact surface with bubbles isolating gas burner valves and hardened gas burner valve and seat surface will be the impact of cavitation, while adding body outlet bushing in place to protect the bullied eclipse the impact site. gas Safety Valve Burner Valve at the outlet bushing plus body as a supplement designed to prevent the liquid collision in the gas burner valve body wall, protecting the gas burner valve by scouring the site, at the same time weaken some noise.
  Plus silencer to the partial pressure of the gas burner valve and sub-noise. This approach is essentially the cavitation condition into a flash conditions to deal with, so applications need to simultaneously trim do to protect hardened gas burner valve.
Epilogue
  Regulating gas burner valve serious noise pollution is not only the environment but will also control gas burner valve factory vibration, vibration can damage the gas burner valve spool and gas Burner Valve seat. The gas burner valve may cause damage to the regulator circuit fault, the interlock device substandard product failures and other issues. Therefore, effective control gas burner valve noise makes our production safer, better environment.

The positioner structure of smart burner valve

     When off, the positioner output is locked, pneumatic actuators maintained at the current position. That is, without any additional accessories, positioning itself to achieve the function off signal to secure his position.

     When off the power, shown in Figure 1, this protection scheme without power, so there is no break in power protection. Have no effect on whether the power pneumatic control Burner Valves position.

     (2) for the use of a nozzle flapper mechanism of smart burner valve positioner:

     Its power supply is connected in series with the input signal circuit burner valve, the off signal / power-up, the locator can automatically detect the abnormal pressure signal output to adjust the pneumatic control burner valve membrane compartment is locked, pneumatic adjustment Safety Valve Burner Valve position is held at fault . That is, without any additional accessories, positioning itself to achieve power, off the signal function to secure his position.

     The foregoing analysis, the structure itself, the use of the seismic performance of piezoelectric smart burner valve positioner burner valve structure better. When using the nozzle flapper mechanism smart Range Top Burner Valve positioner off signals more responsive and simple structure, less attachment, the probability of occurrence of failure in the course is also relatively small.

Stove safety valve selection and installation considerations?

      Many customers in the choice of boiler safety gas stove valves, do not know the selection, resulting in a great security risk. And in the course, I do not know the maintenance and installation of key technologies, also faces
Great danger, especially for higher safety factor requirements for boilers, we now introduce to you on this issue and technologies:

     (l) Rated evaporation is greater than 0.5t / h boiler, installed at least two safety valves: Rated evaporation is less than or equal to 0.5t / h boiler, at least install a safety valve. Separable economizer outlet
At the outlet of the steam superheater safety valve must be installed.
   
     (2) safety valve should be installed vertically at the highest position in the pot business, collection boxes. Between the valve and the drum or header shall be equipped with access steam outlet pipe and valves.
   
     (3) there must be a Safety Valve Burner Valve to prevent the hammer leveraged their own mobile devices and limit leverage deviant guides, spring safety valve should enhance handle and prevent casual twist adjustment screw devices.
   
     (4) For the rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25mm: the rated boiler steam pressure is greater than 3.82MPa, safety valve throat diameter of not less than
20mm.
   
      (5) connected to the safety valve and the boiler pipe, its cross-sectional area not less than the cross-sectional area of the valve imported. If several valves installed together with the short tube in a drum directly connected via a short tube
Channel cross-sectional area should not step on all exhaust valve area 1.25 times.
   
(6) general safety valve should be installed in the exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area, to ensure the smooth flow of the exhaust. Bottom valve exhaust pipe should have received a place of safety posturing sparse
Pipe, the exhaust pipe and the installation of drainage Range Dual Safety Valve are not allowed.
