A Fully Automatic Adjustable Controller for Draining Oil Tank Bottom Water

Abstract

The invention discloses a full-automatic adjustable controller for draining off the water at the bottom of an oil tank, which is characterized in that an openable-closable floating ball valve 4 is arranged on the side wall of a tank body, one end of a drainage tube is connected with a first valve barrel 17, and the other end of the drainage tube is connected with a first floating ball 1 by a connecting rod; the upper end of a second floating ball 8 is connected with a guide bar, and the lower end of the second floating ball 8 can be contacted with a valve seat 9 of the second floating ball 8 so as to form a valve; the upper end of the first valve barrel 17 is the valve seat 9, the inside of the valve seat 9 is provided with a second valve barrel 10, the two sides of the lower part of the second valve barrel 10 are respectively provided with a small hole, the inside of the second valve barrel 10 is provided with a rubber ball which is arranged on a water outlet at the lower part of thesecond valve barrel, and the rubber ball is connected with the bottom of the second floating ball 8 by a communicating rod. The full-automatic adjustable controller disclosed by the invention has theadvantages that: the structure is simple, and the drainage height can be adjusted conveniently, therefore, the full-automatic adjustable controller is suitable for various occasions and media with different oil-water density differences; and through setting waterlines, the full-automatic control on a water drainage process can be realized without man-made operations. Through adjusting a balance weight on the connecting rod, the dead-weight of the floating ball can be adjusted, and an oil-water interface adjusting effect also can be achieved. The full-automatic adjustable controller disclosed by the invention can be widely applied to various oil tanks for storing oils in different types and with different density differences.

Description

technical field [0001] The invention relates to a water drainage controller at the bottom of an oil tank, in particular to a fully automatic adjustable controller for draining water at the bottom of an oil tank. Background technique [0002] During the storage of oil products, a certain amount of bottom water is often stored at the bottom of the oil tank. If it is not discharged in time, it will not only reduce the utilization rate of the oil tank, but also affect the service life of the oil tank due to corrosion and other problems. At present, the method of manually discharging the bottom water is generally used. Because the manual discharge operation is not only labor-intensive, but also has problems with the accuracy of the operation, it often results in the loss of oil products. In the research field of oil storage tank drainage devices, several automatic or semi-automatic oil storage tank drainage devices have been developed at home and abroad, and several patented pro...

AI Technical Summary

Problems solved by technology

[0004] 1. The opening force of the outlet valve is limited, so the discharge volume is limited

[0005] 2. There are strict requirements on the conditions of use, so it is difficult to meet the actual requirements

[0006] 3. The bottom water cannot be drained as required at one time, causing the bottom water to remain in the bottom of the tank and the pipeline for a long time, causing corrosion of the tank and pipeline and freezing and blockage of the pipeline

[0007] 4. The actual conditions of use cannot be adjusted conveniently and effectively

[0008] 5. It is easy to form an equilibrium state, making it difficult to open the discharge valve
