Stainless steel valve

Stainless steel pressure reducing valve Applications: different brass valve and cast iron valve, stainless steel valve more resistant to corrosion, more suitable for a number of acidic media systems, Wuhan far Ming Fung distribution Taiwan imported stainless steel valves, high flow, reduce static and dynamic pressure minus outlet pressure stable and suitable for water treatment, water supply and drainage and steam systems, high temperature high pressure. Stainless steel pressure reducing valve is widely used in water treatment, chemical, food machinery, steam systems, high-rise buildings, urban water supply high pressure area, mine and other occasions, in order to ensure the water supply system in each water point of access to adequate water service pressure and flow. Given the extent of the leakage rate and waste water pressure is almost the same proportion to the size of the water supply system, and therefore stainless steel pressure reducing valve with improved system operating conditions and potential water-saving effect, according to statistics about 30% of its water-saving effect. Stainless steel valve Definition: stainless steel valve by regulating the inlet pressure is reduced to the outlet pressure of a need, and rely on the energy of the medium itself, the outlet pressure is automatically maintained stable valve. From the point of view of fluid mechanics, stainless steel valve is a local resistance to change spending components, that is, by changing the throttle area, so that the kinetic energy of change velocity and the fluid, resulting in different pressure loss, so as to achieve the purpose of decompression. And then rely on regulatory control and regulation systems, so that fluctuations in the valve pressure equilibrium with the spring force, so that the valve pressure was kept constant within a certain error range. Stainless steel valve technical parameters: Material: 304 stainless steel Diameter: DN15-DN50 Connection: double female / double flange Maximum working pressure: 20bar temperature: -15-200 ℃ outlet pressure adjustment range: 0.3-13MPA stainless steel Deals pressure valve basic properties: 1. voltage range: it refers to the output of stainless steel adjustable pressure valve range, to achieve the required accuracy within the required range. The main pressure range and regulating the stiffness of the spring. 2. Pressure characteristics: it refers to the flow rate is constant, because the input pressure fluctuations caused by pressure fluctuations in output characteristics. The smaller output pressure fluctuations, stainless steel valve characteristics better. Output pressure must be less than the input pressure - before setting does not substantially change with the input pressure. 3. Flow characteristics: it refers to the input pressure - timed, stainless steel valve output pressure changes with output flow of support varies. When the flow changes, changes in the output pressure of the smaller the better. Generally the lower the output pressure, which changes with the output flow fluctuations smaller. Stainless steel valve works: stainless steel valve works can be understood as a simple outlet pressure = inlet pressure + spring force, by controlling the internal valve orifice opening size to control the pressure at the outlet, the opening of the small, liquid through the liquid orifice barrier, the greater the pressure loss, the outlet pressure is smaller, the greater the pressure outlet and vice versa.
