High Resistance Alloy is used to produce resistance elementof conductive material.Requirements including High mechanical strength, good corrosion resistance and oxidation resistance. Working temperature is usually at500 ℃. Commonly used with constantan chromium iron, iron chromium aluminum, nickel chromium, nickel, resistivity rho (20 ℃) is 1 Ω was/m or so. It is not used in the conduction of current, but with its high resistance to limit or control the current in the circuit, such as motor, potentiometer, standard resistors, potentiometers, slip line resistor resistance element and resistance line, etc.; For the using of high resistance in the pressure sensor,Temperature compensator and temperature measuring resistor of resistance element to creatte reflect strain, temperature, magnetic field and parameters; High resistance alloy can also be used as heating elements in the manufacture of the resistance heating equipment, could be applied in current, voltage regulating and the winding of control components.

Structural characteristics and uses of high-sensitivity valve: High-sensitivity valve belongs to the pilot piston valve. The main valve and pilot valve composed of two parts. The main valve from the valve seat, the main valve disk, piston, spring and other components. Pilot valve mainly by the valve seat, disc, diaphragm, spring, adjusting spring and other components. By adjusting the spring pressure to set the outlet pressure, the use of diaphragm sensing outlet pressure changes, through the pilot valve opening and closing drive piston to adjust the size of the main valve throttle flow area, to achieve decompression regulator function. High-sensitivity valve in the ordinary valve on the basis of the following improvements have been made to increase the piston area, changing the throttle structure, changing the seal form, improved pilot valve structure and adjust the spring form, which from the following aspects to improve The product's performance. 1, improve the sensing performance of the outlet pressure changes, improve the sensitivity, greatly reducing the pressure deviation due to upstream pressure changes, flow changes and other factors. 2, improved streamline distribution, reducing noise. 3, improved sealing surface structure, extending the sealing surface life. 4, high-sensitivity pressure reducing valve is mainly used for steam pipelines, suitable for large changes in inlet pressure, large steam flow changes in the pipeline.
