Technical Field

The invention relates to the technical field of crude oil treatment, in particular to a double-acting floater connecting rod mechanism for controlling the liquid level of split equipment.

Background

The oil-gas-water three-phase separator is one of the most commonly used devices in the oil field development and production process, and is a solid-liquid-gas three-phase separation device arranged under a pump in an oil-water well of an oil field. The oil-gas-water mixture enters a pre-degassing chamber at a high speed, a large amount of crude oil associated gas is removed by cyclone separation and gravity action, the oil-water mixture after pre-degassing enters a distributor and a washing chamber at a high speed through a guide pipe, the emulsion breaking is carried out in an active water layer containing a demulsifier, the steady flow is carried out, the Reynolds coefficient of the incoming liquid is reduced, the oil flows into a settling separation chamber for further settling separation after coalescence rectification, the degassed crude oil enters an oil chamber after turning over a partition plate and is metered by a flowmeter and flows out of a separator after control, and the water phase enters a water chamber through a guide pipe by means of pressure balance, so that the purpose of.

At present, an adjustable pipe section is generally arranged at a water outlet of a communicating pipe for the oil-water interface of a three-phase or two-phase horizontal separator, and the oil-water interface of a mixing chamber is adjusted by directly lifting the height of the adjustable pipe section through the tank inlet of an operator after production stoppage and tank cleaning. The method has the defects that the adjustment can be carried out only after production stop and tank cleaning, so the method has more complex working procedures, higher consumption and longer period.

Disclosure of Invention

The invention aims to provide a double-acting float connecting rod mechanism for controlling the liquid level of split equipment, which can solve the technical problems that an oil-water interface can be adjusted only after production is stopped and a tank is cleaned, the working procedure is complex, the consumption is high, and the period is long.

In order to achieve the above purpose, the invention provides the following technical scheme:

the utility model provides a two effect float link mechanism for controlling components of a whole that can function independently equipment liquid level, includes oil gas separation chamber and subsides the water purification chamber, it is connected with float link mechanism through the ring flange to subside on the water purification chamber, float link mechanism includes floater and connecting rod, the floater is located subsides water purification intracavity portion, the connecting rod runs through subside water purification chamber outer wall and with floater fixed connection, the other end of connecting rod is connected with into water control valve and goes out water control valve.

Through setting up water control valve and play water control valve, can realize that the liquid level in oil gas water separation chamber and the settlement water purification intracavity links each other. When the liquid level in the sedimentation water purification cavity is lowered, the water outlet control valve reduces the opening degree, the sewage in the sedimentation water purification cavity is reduced through the output of the water outlet control valve, the opening degree of the water inlet control valve is increased, the liquid output in the oil-gas-water separation cavity is increased, and the operation is a negative-acting valve.

Preferably, the oil-gas-water separation cavity is connected with the sedimentation water purification cavity through a water inlet pipeline, the water inlet pipeline is connected with the water inlet control valve, and the water inlet pipeline is provided with a first valve.
