Pressure differential single
Gas Water Heater Valve seat seal valve body is forged, single-seat sealing structure shown in Figure 2. Cone seal between the valve stem and valve seat, stem size with streamlined structure design, make the water go smooth path in the flow process. The heater valves sealing surface CoCr alloy, corrosion, erosion, corrosion, the percentage of the stem in different ways and can be easily realized, such as linear and other regulation characteristics. To avoid packing discontinuity occurs leakage, packing middle set packing spacer rings. To prevent rotation gland, affecting water flow, the valve cover to set the anti-rotation screws. To prevent packing broken water pipes inside inflows temperature and pressure reduction nozzle clogging device, the pressure sleeve and the seat, under the seat and valve embedded (Figure 3). Under pressure differential case, since it is easy to generate cavitation, the use of multi-level adjustable structure to eliminate cavitation and damage the valve problems.
The valve stem and the valve seat is a key component of this, the quality of the sealing surface will directly affect the overall performance of the valve. The traditional single-seat single-valve structure oriented processing method is not reasonable. Its process method for the valve body and valve seat body welding, to make the stem and the valve seat deformation with the gap is relatively large, after packing deform easily washed into the
Water Heater Gas Valves portion of the lumen. Now the process method to a single-seat twin valve guide structure, the pressure sleeve and embedded under the seat, stem and seat directly with the seal in order to achieve zero leakage effect.
