Pneumatic Diaphragm Type Trap< )r , , Introduction:

< )r , ,
Pneumatic Diaphragm Type Trap< )r , , is a new generation steam trap specially developed, designed and produced based on the hydrophobicity of thermal power plant equipment. The pneumatic membrane type trap has a near-linear flow design, which reduces flow resistance. The secondary throttling principle reduces erosion and improves service life.

< )r , , Features of Pneumatic Diaphragm Type Trap:

< )r , ,
Pneumatic Diaphragm Type Trap < )r, , The upper part of the valve consists of a valve cover and a stuffing box, which facilitates quick disassembly and in-situ maintenance. The structure of the inclined valve stem and the optimal flow channel shape design make the medium close to a straight line. The valve has the best value and produces a lower pressure drop than other types of valves.

< )r , , The carbide sealing surface is overlay-welded with a special process on the valve body (the surface of the sealing surface has been integrally hardened), making the structure more compact. The tapered sealing surface design enables sealing with smaller axial force, providing reliable sealing and long service life.

< )r , , The valve disc guided by the valve body cavity has two upper and lower guide rings. The top and bottom of the valve disc are guided at the same time, forming a whole process in the valve body cavity. The guided piston valve disc can eliminate jamming, surface scratches, valve stem bending, valve disc vibration and other phenomena caused by various improper forces. The guide ring at the bottom of the valve disc allows 50% of the fluid to pass in a nearly straight line, effectively eliminating all adverse reactions caused by side impacts. These characteristics make the valve very suitable for rapid steam discharge and drainage systems in power plants.

< )r , , The valve disc sealing surface is overlayed with hard alloy. This alloy has excellent mechanical properties, is resistant to wear and erosion, and can maintain the long-term use of the valve. life.

< )r , , The valve stem packing adopts imported special packing, which can achieve the best leak-proof effect, is durable, and is easy to disassemble and assemble. The seal between the stuffing box and the valve body is made of high-mesh flexible graphite pads and assembled with a predetermined torque, which is safe and reliable and prevents external leakage.

< )r , , The pneumatic device is used as the actuator to control the valve accurately, safely and effectively.

< )r , , The stuffing box adopts a special structural design to ensure sufficient strength and good thermal properties.

< )r , ,
Pneumatic diaphragm trap< )r , , The valve core and seat are made of solid carbide to close the internal leakage stage and the middle chamber is removable The sealing design prevents leakage and facilitates maintenance. It can also be used in flammable and explosive situations. According to the signal from the control system or regulating instrument, the valve can be cut off or opened to achieve the use requirements of the controlled parameters. Therefore, it is widely used in remote control of thermal power plants and other industries.
