Circular Disc Type Drain Valve
Introduction:
Disc drain valve is used in steam pipe network and equipment, which can automatically discharge condensate, air and other non condensable gases, and prevent water and steam leakage.
The disc drain valve plays a role of blocking steam and draining water in the steam heating system. Selecting a suitable drain valve can make the steam heating equipment reach the highest working efficiency. To achieve the best results, it is necessary to have a comprehensive understanding of the working performance and characteristics of various types of steam traps. This type of valve shall be installed horizontally in the pipeline.
There are many kinds of steam traps, each with different performance. When selecting steam trap, its characteristics should first be selected to meet the best operation of steam heating equipment, and then other objective conditions should be considered. In this way, selecting the steam trap you need is correct and effective.
The steam trap must be able to “identify” steam and condensate, so as to prevent steam and drain water. The “identification” of steam and condensate is based on three principles: density difference, temperature difference and phase change. Therefore, three types of steam traps are manufactured according to three principles: mechanical type, thermal static type and thermal dynamic type
Mechanical
Actions depend on the change of condensate water level in steam trap, including:
1. Float type: the float is a closed hollow sphere;
2. Open upward float type: the float is a bucket type with open upward;
3. Open downward float type: the float is a bucket type with open downward
