Shanghai Qigao Pump and Valve Group

Lever float type steam trap
Performance advantages
It can continuously discharge saturated condensate water without water accumulation in heating equipment, thereby obtaining the highest thermal efficiency.
. It will not be affected when the steam pressure changes. The float drives the lever to automatically adjust the opening of the valve seat hole. It works continuously and has stable performance.
. It has good air exhaust performance. The automatic air exhaust device can discharge non-condensing hot and cold gases without air lock, and the operation is smooth and noise-free.
Excellent sealing performance. The seal adopts spherical sealing, which has a long service life without concentrated wear during operation.
Purpose
Used in steam heating equipment and condensate recovery systems and working conditions that require rapid removal of condensation water. It can automatically, quickly and continuously remove condensation water, effectively prevent steam leakage, and obtain the best heating effect.
Working Principle
When the valve is first activated, the automatic air exhaust device quickly removes non-condensable gas from the system. When steam and hot condensate enter, the temperature in the valve cavity increases, and the air exhaust device automatically closes. The float rises and falls according to changes in the condensate level, driving the lever to adjust the opening of the valve seat hole, and continuously discharges condensate. . When the condensate stops entering, the float falls by its own weight, driving the lever to drive the valve core to close the drainage valve seat hole.
Use and maintenance
It should be confirmed whether the material of the valve body, the maximum pressure and temperature can meet the requirements of the working conditions.
. The pipes must be cleaned and debris removed before installation.
The installation location should be as close as possible to the heating equipment.
, should be installed horizontally at the lowest point of the pipeline, with the flow direction consistent with the direction marked on the valve body.
Each heating equipment must be equipped with its own drain valve to avoid affecting each other.
When ensuring that the system can operate safely, slowly open the valve of the drain valve to gradually heat it up to a normal state.
, Regular maintenance is required to ensure the normal operation of the trap.
The selection is mainly based on
Condensate load (discharge volume) / (select magnification times)
Maximum working pressure
Working pressure difference
Valve body material and nominal pressure
Connection method and size
Main overall dimensions
