Description

Exhaust valve for water mixing heat exchange tank

Technical Field

The utility model belongs to the field of oil field oil recovery gathering and transportation, in particular to an exhaust valve for a water-mixing heat exchange tank.

Background

In the process of oil exploitation, crude oil in an oil well is generally low in temperature and high in viscosity, and a pipeline is easily blocked in the crude oil conveying process, so that the crude oil in the pipeline is subjected to water mixing heat exchange by a water mixing heat exchange tank in the crude oil conveying process, and the blockage of the pipeline by the crude oil is avoided.

After the cold mixed water in the water mixing and heat exchanging tank is subjected to heat exchange to form hot mixed water, the mixed water can be vaporized and continuously separated out from the liquid, and if gas is not discharged in time, a water pump at the outlet of the water mixing and heat exchanging tank is pumped out, so that the water pump is damaged. In the related art, the exhaust valve is arranged at the top of the water-mixing heat exchange tank, so that the gas in the water-mixing heat exchange tank is exhausted.

After the crude oil is transported, the water blended in the crude oil is separated and then is recovered to the water blending heat exchange tank under the action of gravity under the condition of high terrain, so that the water blending heat exchange tank is replenished with liquid, and the water blending heat exchange tank is filled with the liquid. The exhaust valve needs to be kept in a closed state during liquid replenishing and non-exhausting so as to prevent leakage of the mixed water. Therefore, the operator needs to open the exhaust valve during the exhaust and close the exhaust valve during the fluid replacement and the non-exhaust, so that the exhaust efficiency is low due to the continuous manual opening and closing of the exhaust valve.
