Structure characteristic and use

YG13H internal thread high sensitivity steam pressure reducing valve belongs to the pilot piston type pressure-reducing valve. From the main valve and pilot valve composed of two parts. Main valve mainly comprises a valve seat, the main valve disc, piston, springs and other parts. Mainly by the pilot valve seat, valve, diaphragm, spring, adjusting springs and other parts. Adjusting the spring pressure by adjusting the outlet pressure setting, using changes in outlet pressure sensing diaphragm, through the pilot valve opening and closing the main valve piston adjusting throttle position for driving the flow area of the size, to achieve decompression function.

This series of products in the ordinary decompression valve base made the following improvements, increase the piston area, changing the throttle structure, changes the sealing form, improved pilot valve structure and adjust the spring form, which from the following aspects of improving the performance of the product.

1, improve the outlet pressure change sensing performance, improved sensitivity, greatly reduced due to the upstream pressure, flow changes caused by factors such as the pressure deviation.

In 2, to improve the streamline distribution, reduces noise.

3, improved sealing face structure, prolongs the life of sealing surface.

The products are mainly used in steam pipeline, applicable to the variation of the inlet pressure, the flow changes Steam pipeline.
