Overview

As the development of the national petroleum chemical industry and increasing the storage tank, safety protection and environmental management problem increasingly, tank farm and outside completely cut off and rainwater drainage is the contradiction between the long failed to solve the difficult problem, the past generally USES the manual valve and cover plate to control emissions rain, rain when open drain valve, sunny closing valves, the operation of trouble, rainy day after no keeping open valve general. If the oil tank farm happen at this time run accident, oil tank, the outflow, with manual valve drainage will also be left on the ground with rained and oil discharged, waste oil and pollution of the environment, and easy to produce the fire, the domestic several major oil tank area fire accident and oil tank area row rain ran about oil, to the state and people’s life and property caused significant.

This product to meet GB50351-2005 “storage area fire prevention dam design specification of the requirements of the 3.2.8 page 38 article:” codes in the research process found group now, many of the storage tank area drainage equipment a crumbling “tank area DiNa drainage problems concerning safety is one of the important aspects of the, for the thorough settlement of this issue, and put an end to the safety hidden danger of and so on, in the standardization of have to put forward the strict request to tank area should be set up safe and reliable cut oil duct drainage equipment, absolutely avoid the disclosure.

This product conforms GB50074-2002 “oil depot” code for design and GB50160-92 “petroleum chemical enterprise of the code for fire protection design rules.

1. Working Principle

This product according to the characteristics of different oil and water density, rely on the buoy in oil medium to achieve poor buoyancy oil interception drainage. When heavy sand well had the water, and to a certain height when floating pontoon, through the leverage as long as small force can will pressure reducing valve open, and to make the drain valve core air vents in the open, water from the drain valve into a tank inside, realize the reduced pressure, buoy continue to rise, will drain valve open, water from the drain valve into a tank inside, by a tank drainage. Heavy sand in well when the media is oil, pontoon to sink, through the lever will pressure reducing valve core of vents of closed, then will drain valve closed, prevent oil were leaked. When the weather is dry sand sink in well when there is no water and drain valve to be automatic remains closed. When oil discharge system is medium area oil and water mixture ? state

2. Product features

This product USES no back pressure special design structure, lever drive valve needle moving, make internal and external pressure valve core consistent, lever continue to move, the needle valves and valve is very flexible began together drainage, and therefore solve the pressure reducing valve and drain valve asynchronous phenomenon, overcome the disadvantages of closing the lax, ensure safety terminal;

Do not require any energy realization of automatic control, safety, environmental protection, economy;

Small volume, reasonable structure, without wearing parts, long service life, no need to add water, use convenient maintenance;

When water open automatically, without water shut off automatically when drought, oil and water mixture of automatic when oil separation, this equipment 24-hour all-weather work, reduced the operators open valve, when it rains it closing valves pressure of work, to eliminate the run oil accidents.

7. Note

1、Oil tank farm to sink in the sand well drain must have the grille, does not allow debris flow into the sink sand in the well, causing the drain valve failure.

2、Install and remove heavy sand in well sundry, staff to use up the ladder, shall not use the ladder for buoys, otherwise, it will cause the drainage device oil interception of valve leakage and leveraging the bend or break.

3、To remove the impurities in the gutters regularly and sediment, otherwise, it will affect the drainage device valve opening and closing.

4、To timely collect sink in well integrated oil sand.

5、This equipment has been tested before they leave the factory, don’t adjust. According to the steps can use assembly.

6、Cut oil is a tank and the drainage pipe connection must keep perpendicular installation.

AccessoriesHow to install Automatic oil interception drainage device in cold areas

In cold north area temperature season, a belt of deep. To prevent sink drain well and the sand winter freezes, automatic cut oil tank, guarantee the use effect of drainage device, installations will automatically cut the drainage device drain oil parallel buried in a belt of the line, so as to achieve the local table icy sand drain well and sometimes sink ice-free purpose, make sure to be automatic oil interception drainage device from the influence of the temperature difference between season, the perennial water discharge automatically, and oil to be automatic intercept, no water automatically shut off.
