1, Overview
High differential pressure water
Gas Water Heater Valveis widely used in industrial fields of electric power, metallurgy, petrochemical, textile, heating, cooling, paper and coal chemical temperature and pressure reduction devices in the core components of a direct impact on temperature and pressure reduction device performance. Traditional water Gas Water Heater Valve easy cavitation Gas Water Heater Valve packing breakable chance of leakage is relatively large, the emergence of the phenomenon of water clogging. At the same time, the requirement for drastic change of working conditions and increase the complexity of the process parameters, temperature and pressure reduction devices often there will be some problems in the regulation of performance and safety performance. Pressure differential single water Gas Water Heater Valve seat seal structure, process, and other aspects of reliability and cost reduction has greatly improved and perfected to meet the requirements of drastic change working conditions and complex process parameters.
2, structural features
Pressure differential single-seat seal
Water Heater Gas Valve (Figure 1) from the Gas Water Heater Valve body, Gas Water Heater Valve cover, seat, stem, press kits, packing, spacer ring and electro-hydraulic actuators and other components. Gas Water Heater Valve open, closed or opened by adjusting the pressure transmitter and the regulator, and then manipulated by the actuator to drive the Gas Water Heater Valve stem so that the stem moves up and down in the seat, to change the flow area of the medium to change the flow. Water from the inlet Gas Water Heater Valve into the upper chamber. When moving up and down the stem, so that the water channel through streamlined cone, run down into the upper, middle and lower seat chamber. By adjusting the relative position of the Gas Water Heater Valve stem within the
Gas Valve For Water Heaterseat, the flow area control cone, in order to change the flow area of the medium to achieve the purpose of adjusting the flow rate.
