Inverted bucket pilot-operated steam trap
Other Products
I. Introduction:
The inverted bucket pilot-operated steam trap is designed to discharge condensate, air, and carbon dioxide from steam systems while automatically preventing steam leakage to the greatest extent possible. There are many types of steam traps, each with different performance characteristics. When selecting a steam trap, first choose one whose specific performance meets the operating requirements of the steam heating equipment, then consider other objective conditions. This is the correct and effective way to select the desired steam trap. The function of a steam trap: Equipment that uses steam only needs steam. Condensate will definitely be produced inside such equipment, and this condensate becomes a harmful fluid. At the same time, air and other non-condensable gases mix in, which cause equipment failures and reduced performance.
II. Precautions:
1. Clean the piping and equipment before installation to remove impurities and prevent clogging.
2. Steam traps should be installed as close as possible to the bottom of steam-using equipment and in locations with good drainage.
3. Steam traps should be installed in easily accessible locations for maintenance, and arranged as concentrated as possible for convenient management.
4. Each steam heating equipment should be equipped with an individual steam trap.
5. The bypass pipe must not be installed at a lower level than the steam trap.
6. During installation, ensure the arrow direction on the valve body is consistent with the flow direction of the piping medium.
7. The piping at the inlet and outlet of the steam trap should have a downward slope of 4%, and the nominal diameter of the piping must not be smaller than that of the steam trap.
8. If the drainage capacity of a single steam trap is insufficient, multiple steam traps can be installed in parallel. In locations where freezing may occur, antifreeze measures must be taken.
III. Features and Performance:
1. Strong adaptability to condensate generation, capable of both intermittent and continuous discharge.
2. Equipped with a large-capacity double-seat differential mechanism and SCCV closing system, delivering large drainage capacity in a compact size.
3. All internal parts are made of stainless steel and mounted on the valve cover, making maintenance extremely convenient.
4. Back pressure rate up to 90%.
5. Reliable steam-water separation: Steam and water enter from the lower part of the valve body through a U-shaped channel, and the valve is always in a water-sealed state, effectively preventing steam leakage.
6. The open-type float resists water hammer, and the bucket has no overflow vent holes, effectively preventing steam lock and air blockage.
7. Combined with a lever mechanism, it can be manufactured as a high-pressure valve.
IV. Working Principle:
The inverted bucket pilot-operated steam trap has only one half-float bucket as the moving component, with the opening facing downward. The bucket serves as both the opening and closing element and the sealing element. When the device is just started, air and low-temperature condensate in the pipeline enter the steam trap through the discharge pipe. The bimetallic air vent element pops the bucket open, the valve opens, and air and low-temperature condensate are quickly discharged. When steam enters the bucket, the bucket generates upward buoyancy. At the same time, the temperature inside the valve rises, causing the bimetallic air vent element to contract. The bucket floats toward the valve seat, and the valve closes. When the steam inside the bucket turns into condensate, the bucket loses buoyancy and sinks downward, the valve opens, and condensate is quickly discharged. When steam enters the bucket again, the valve closes, and the cycle repeats, enabling intermittent and continuous operation. Since the valve seat is isolated by a water seal, steam and water are separated, resulting in no steam leakage during operation.
