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.
