1 Equipment Introduction With the rapid development of my country's petrochemical industry, fire safety issues have become increasingly prominent. According to the provisions of the "Petroleum Depot Design Code" and "Petrochemical Enterprise Design Fire Protection Code", in order to ensure the safety of the oil tank area, the rainwater drainage and sewage discharge outlets of the oil tank area fire dike should be equipped with drainage and oil separation devices.

Description: The main body is made of stainless steel, that is, the large and small connecting rods, large valves, small valve floats and front and rear movable shafts are stainless steel. The counterweight is
carbon steel chrome-plated, and the valve body and flange are carbon steel hot-dip galvanized. The flange pressure is
This product has the following obvious advantages
Large drainage capacity, complete models, the main body is stainless steel, and has strong corrosion resistance. Flexible rotation, reliable operation, long service life
Small size, easy maintenance, no need to replenish water, easy management in winter
Using a double-valve pilot structure, no power is required, so it is safe. The technology has a high starting point, and the action is sensitive and reliable. When there is oil, it can trap the oil in the embankment. The valve automatically closes when there is no medium, ensuring the safety of the oil tank area.
This product is controlled by the difference in buoyancy of the floating body in the medium. Generally, the density of oil ranges from , while the density of water ranges from .
Two Application Scope
Applicable Oil Range
Tips: This valve is suitable for oil/oil products.
Can
When there is no medium in the drainage system, the valve will be closed
When the medium in the drainage system is water, such as the rainwater valve, the rainwater or sewage will be discharged in time
The medium in the drainage system When supplying oil, for example, when the oil is leaking out in an accident, the valve is closed to prevent the oil from leaking out and causing an accident.
Way
Installed in the drainage pipelines of production equipment and oil tank areas in the petrochemical industry, it plays the role of oil interception and drainage.

Installation precautions
The connection form of the drainage valve is flange connection, and the flange is
The debris in the sand settling well should be cleared away. Normal maintenance usage to ensure normal operation.
