Structural characteristics and use of high-sensitivity steam valve: High-sensitivity steam valve is 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 steam valve on the basis of the ordinary pressure relief valve made the following improvements, increased piston area, changed the throttling structure, changing the seal form, improved pilot valve structure and adjust the spring form, which from the following aspects Improve product 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 steam valve is mainly used for steam pipelines, suitable for large pressure changes in imports, large steam flow changes in the pipeline.

OTIS Moving Walkways 606 NCT |
| The sheer number of passengers a commercial Trav-O-Lator® carries, demands that safety has to be the overiding concern. In this respect the Otis 606 NCT's performance is unsurpassed. By way of example, tapered deflectors prevent objects from entering the handrail entry box (a design unique to OTIS). Trolleys can be transported in safety. And the balustrade, with an ideal 1000 mm height at landings, is constructed of 10 mm thick safety glass. |
