Abstract

The utility model provides a dual-chamber drain valve. An oil storage tank adopts artificial drainage in the oil industry; as the boundary of oil and water is unclear, large quantity of oil material is usually drained out during the draining, wastage and pollution are caused. The utility model adopts the dual-chamber structure of forward flow and counter flow, and a floating ball and a valve clack are connected, so the water is automatically drained and the oil is left. The utility model can also be used for the separation and automatic drainage of other two liquids which are incompatible and have different densities. When the utility model is universally used in the oil industry, tens of oil can be saved each year, workers' labor intensity is reduced, and the environmental protection is improved.

Description

Dual-chamber steam trap

The utility model belongs to valve, particularly a kind of separating oil, water two-chamber drain valve of being used for.

Existing a kind of steam lever float ball type drain valve is mainly used on steam heating pipeline and the heat transmission equipment.It has only valve pocket, ball float and a lever system, and valve nozzle, flap all are placed within the valve pocket.Because oil, the water density difference is very little, the buoyancy difference that ball float produces is also very little, thereby this drain valve is not suitable for the hydrophobic automatically of oil storage tank in the petroleum industry.And artificial drainage because the profit boundary is unclear, is easily discharged a large amount of oil plants, causes waste and pollution.

The purpose of this utility model provides a kind of automatic hydrophobic device of oil storage tank in the petroleum industry that is applicable to.

The purpose of this utility model realizes by the technological scheme of following two-chamber drain valve.It is made up of valve body, ball float, lever, valve nozzle, flap, it is characterized in that valve body is made as following current, adverse current two-chamber, and ball float places following current chamber, valve nozzle and flap to place the adverse current chamber, with lever ball float is connected with flap.The profit inlet is located at top, following current chamber, and drain opening is located at bottom, adverse current chamber and communicates with valve nozzle.

Fig. 1 is the utility model structural representation and summary figure.

Fig. 2 is used for the automatic hydrophobic embodiment's schematic representation of oil storage tank for the utility model.

The utility model is described in further detail below in conjunction with accompanying drawing.

Profit is because of separation by gravity in the oil storage tank, depositing in water at the bottom of jar, open stop valve after, water at first 1 enters following current chamber 2 ball float is floated from entering the mouth, by lever 4 flap 5 of float valve 10 is opened, water is upwards discharged from exporting 7 through valve nozzle 6 adverse current chamber 8 from bottom, following current chamber.When having arranged for water base, oil or oil-water mixture in the storage tank enter the following current chamber, because density is lower than water, buoyancy reduces, and ball float sinks, and drive flap by leverage valve nozzle is closed.Because the following water of valve nozzle has not thoroughly been arranged, in the adverse current chamber, form water seal counter-flowing path is sealed, oil or oil water mixture just are enclosed in the following current chamber.When water continuation deposition reach a certain height the water that flows into the following current chamber, ball float floated once more, and water outside the expulsion valve of adverse current chamber, so goes round and begins again again, and oil is hindered in the following current chamber all the time, and water then is discharged into outside the valve.

The utility model has the advantages that and ball float buoyancy to be amplified the variation by the lever arm ratio, produce enough moment with the valve nozzle breakdown or close. Owing to adverse current after the first following current, when oil did not also reach the valve pocket bottom, valve had moved and has cut out again, the oil lighter than water is enclosed on the water surface, realizes the purpose of draining oil resistance, the sediment contamination heavier than water is sunken under water simultaneously, can the upper reaches stop up valve nozzle, can be located at mud hole 9 regular discharges at the bottom of the valve from other.

Claims

1, two-chamber drain valve, form by valve body, ball float, lever, valve nozzle, flap, it is characterized in that valve body structure is the following current chamber, adverse current chamber two-chamber, ball float places the following current chamber, and valve nozzle, flap place the adverse current chamber, and ball float is connected by lever with flap, the profit inlet is located at top, following current chamber, and drain opening is located at bottom, adverse current chamber and communicates with valve nozzle.

2, according to the described two-chamber drain valve of claim 1, its feature also is to be provided with mud hole at the bottom of the valve.
