Product Name: Internal thread inverted bucket drain valve 981/982/983/984/985/986

Product Introduction:

Internal thread inverted bucket steam trap valve 981/982/983/984/985/986 thread inverted bucket steam trap valve/inverted bucket steam trap valve/inverted bucket steam trap valve/internal thread inverted bucket steam trap valve/thread inverted bucket steam trap valve is based on the working principle of using the density difference between condensed water and steam. The internal structure is connected to the inverted bucket by a lever system, overcoming the steam pressure switch. The internal part of the inverted bucket is a liquid level sensitive component, and the opening of the inverted bucket is downward. The device can quickly increase the temperature and automatically discharge air. The inverted bucket is connected to a lever to drive the valve core to open and close the valve, which works in a cyclic manner and intermittently discharges water.

Principle and function:

When steam condenses, it releases the enthalpy of evaporation to form condensed water, which only contains the enthalpy of saturated water. In order to ensure the high heat transfer efficiency of the system, condensed water must be removed from the system. The air and other non condensable gases carried in steam that form a thermal resistance layer on the steam and heat exchange surfaces must also be removed from the system. The basic function of a steam trap is to quickly remove condensed water, air, and carbon dioxide gas from the steam system; Simultaneously, it automatically prevents steam leakage to a maximum extent.

According to their different principles and functions, steam traps can be divided into the following three types: mechanical type, which operates by relying on changes in the height of the condensed water level inside the steam trap; Thermostatic type~operates based on changes in liquid temperature; Thermodynamic type~It operates based on the changes in the thermodynamic properties of the liquid. When the drainage capacity of a steam trap cannot meet the requirements, several steam traps can be installed in parallel.

The bucket type steam trap utilizes the working principle of the density difference between condensed water and steam. The internal structure is connected to the inverted bucket by a lever system, overcoming the steam pressure switch. The inverted bucket type steam trap has a liquid level sensitive component inside, with the opening of the inverted bucket facing downwards. When the device is just started, air and low-temperature condensed water appear in the pipeline. At this time, the drain valve is fully open, and the air and low-temperature condensed water are quickly discharged. The device quickly raises the temperature. When steam enters the inverted bucket, it generates upward buoyancy, and the connecting lever of the inverted bucket drives the valve core to close the valve. There are small holes on the inverted bucket that can automatically release air. When a part of the steam is discharged from the small holes and another part of the steam produces condensed water, the inverted bucket loses buoyancy and sinks downwards. The connecting lever of the inverted bucket drives the valve core to open the valve. When the steam enters the inverted bucket again, the valve closes again, the cycle works, and the drainage is interrupted.

Performance characteristics:

1. The structure is simple and not prone to malfunction. No pin or hinge structure, no fixed wear, good energy-saving effect. Wear resistant chrome steel valve seat, stainless steel structure, long service life.

2. Intermittent discharge of impurities can be washed away without accumulating dirt, and the air is automatically discharged.

3. There are multiple options for throttling holes, which can achieve * drainage flow rate at different pressures.

4. All internal components are installed on the valve cover for easy maintenance.
