GYA hydraulic safety valve

GYA hydraulic safety valve is (valve) breathing valve safety standby equipment, its suction and expiratory pressure is slightly higher than (valve) breathing valve, in the breathing valve once failure or in winter when the valve freeze, the hydraulic safety valve liquid seal is destroyed to protect the oil tank from damage. The hydraulic safety valve is installed on the top of the oil tank and used in conjunction with the breathing valve. Control pressure: +56 mm water column to -50 mm water column.
  

GYA hydraulic safety valve dimensions and connection dimensions

Main items of safety valve order:

Safety valve medium, pressure level, opening mode (full opening/micro opening) set the take-off pressure, determine the valve size, connection mode, standard maximum temperature resistance, release flow/hour, valve body material, internal valve body structure, working principle, installation instructions and other related technical data. Safety valve selection is mainly based on (take-off pressure and neat pressure flow temperature) caliber general design institute will be given, and in fact through the steam pressure, flow and take-off pressure, you can infer the size of the safety valve. Generally, it will be smaller than the caliber selected by the design institute. When the occasion is very important or the environment is more complex, please try your best to provide design drawings and detailed parameters, by our Xuan Cheng valve company experts for your review.

Xuan Cheng valve order must

1, according to the use of places, uses, and understand the relevant regulations, specifications, standards, guidelines, permissible approval can be selected for various requirements of the valve
2, confirm the valve working conditions, use specifications, applicable media, corresponding material, mode of operation, working pressure, medium temperature;
3, determine the nominal diameter that matches the pipeline: DN(mm), NPS(");
4, determine the connection with the pipeline: flange type, internal (external) thread type, welding type, clamp type, clamp type, sleeve type, etc.
5, determine the driving mode of valve operation: manual, worm gear transmission, pneumatic, electric, hydraulic, electromagnetic, electro-hydraulic, etc.;
6, confirm the type of valve: ball valve, gate valve, butterfly valve, globe valve, check valve, regulating valve, solenoid valve, safetyvalve, pressure reducing valve, trap valve, needle valve, Angle seat valve, diaphragm valve, balance valve, filter and other special valves;
7, determine the use of the valve: switch type, control type, safety type, automatic type, discharge type, etc.;
8, determine the valve shell and internal materials: carbon steel, alloy steel, stainless steel, ductile cast iron, gray cast iron, copper alloy, aluminum alloy, plastic, etc.;
9, determine the sealing performance requirements of the valve, sealing grade or sealing leakage;
10, determine the valve protective coating requirements, packaging requirements, transportation requirements;
11, the special needs of the valve should also be determined: structural length, valve height, appearance size, flow resistance, discharge capacity, flow characteristics, protection level, explosion-proof performance and other parameters;
12, determine the installation position and posture of the valve.
