Description
Technical Field
The present invention belongs to the field of petrochemical technology, and is especially one pipeline for gas-liquid separation and automatic selection of gas path and liquid path in water supply. Specifically, in a pipeline for mixing incoming liquid mixed gas-liquid components or gas-section liquid-section mixed components, gas and liquid are separated and respectively led into a gas path pipeline and a liquid path pipeline, so that the gas path and the liquid path after the separating valve are not mixed with liquid and the liquid path is not mixed with gas.
Background
At present, gas-liquid separation in the field of petrochemical industry is carried out through a large-scale separation device, and the device is large in size, multiple in accessories and complex in structure. In the water supply field, separation equipment is not used in a gas-liquid mixing well, and the water is directly supplied to users, so that the condition that tap water is mixed with underground natural gas is generated, the environment is damaged, and the life and property safety of people is threatened. At present, a special valve for separating gas and liquid media of a pipeline does not exist.
Disclosure of Invention
The gas-liquid separation device aims to separate gas in a liquid conveying pipeline and liquid in the gas conveying pipeline or separate gas components and liquid components which are subjected to gas-liquid separation into a gas path and a liquid path, so that gas leakage and liquid leakage of the liquid path are avoided. The invention can separate gas-liquid mixed liquid and can also be used as a gas path and liquid path separation valve to realize the separation of a gas path and a liquid path.
The scheme adopted by the invention for solving the technical problems is as follows:
the invention is composed of a cavity (4), two funnel-shaped cavities (the top end is provided with an annular boss), a counterweight floating ball, an inlet (connected with a cylindrical cavity), an air outlet and a liquid outlet.
Main chamber (4):
the inner cavity can be a cylinder, a cuboid or a cube, and the corresponding funnel-shaped cavity corresponds to the conical (circular arc) cavity and the square funnel-shaped cavity (the inner annular boss is unchanged).
Counterweight floating ball (7):
the density of the floating ball is less than that of the liquid medium, and the following formula is required.
Floating ball buoyancy-L > floating ball gravity > L
Description of the drawings:
l is the sum of the pressure gradient of the inner cavity and the outlet output pipeline and the friction force of the floating ball and the inner annular boss.
The diameter of the floating ball meets the following conditions:
cross sectional area of main cavity-cross sectional area of floating ball > cross sectional area of inlet
An inlet 1:
the diameter of the inlet is the same as that of the separated pipeline, and the connection mode can adopt various connection modes such as welding, flange connection, quick joint and the like
And (3) an outlet 2:
the diameter of the outlet pipeline is less than or equal to that of the inlet, and the outlet pipeline is connected with the funnel-shaped cone body, and the external connection mode can adopt various connection modes such as welding, flange connection, quick joint and the like
And (3) an outlet:
the diameter of the outlet pipeline is less than or equal to that of the inlet, and the outlet pipeline is connected with the funnel-shaped cone body, and the external connection mode can adopt various connection modes such as welding, flange connection, quick joint and the like
A funnel-shaped cavity:
and if the main cavity body is a cylinder, the funnel-shaped cavity body is a circular cone, and the inner wall of the funnel-shaped cavity body is smoothly connected with the inner wall of the outlet of the inner wall of the main cavity body. If the main cavity is a cuboid or a cube, the funnel-shaped cavity is a square cone, and the inner wall of the funnel-shaped cavity is smoothly connected with the inner wall of the outlet of the inner wall of the main cavity.
Annular boss:
the top ends of the two funnel-shaped cavities are respectively connected with the funnel-shaped cavities, the caliber of the two funnel-shaped cavities is the same as that of the outlet pipeline. The main effect is to block up the outlet pipe with the floater cooperation, reduces the lateral wall area of contact when the floater is pressed to annular boss simultaneously, reduces frictional force, sealed export.
The height of the annular boss is slightly larger than the positions from the floating ball to the top and the bottom, so that the pipeline is guaranteed to be blocked.
The combination mode is as follows:
The working process is as follows:
when no medium enters, the floating ball rolls to the platform at the bottom along the inner wall of the conical cavity at the lower part under the action of gravity to block the night path outlet.
When a liquid medium (or a gas-liquid mixed medium) enters the cavity, the liquid medium covers the floating ball, the floating ball floats when the buoyancy is larger than the gravity of the floating ball, the blocked liquid path platform opening is opened, and liquid flows out from the liquid outlet.
When the liquid flow is large, the wall body is filled with liquid, the floating ball floats upwards to the upper platform outlet position under the action of buoyancy force to block the gas path outlet, and liquid media can not enter the gas path pipeline along the gas outlet.
When liquid flow diminishes, during gas flow grow, liquid flows out from the liquid outlet, and gaseous gathering on cavity upper portion, liquid level decline, and when the floater was floated and is less than the floater gravity, the floater broke away from with upper portion gas outlet platform, opened the gas outlet, and gas is along the gas outlet.
When gas further increases, the liquid outlet continues to flow out liquid, the liquid level continues to descend, the floating ball position descends along with the liquid level, the liquid outlet is blocked by the bottom platform along the inside of the lower conical cavity under the action of gravity, and gas media are prevented from entering the gas circuit along the liquid outlet.

The method can be used in the field of petrochemical industry with higher safety requirements, can also be applied to degassing treatment and utilization of underground water, and is safe and environment-friendly. The blank that the pipeline component does not have a gas-liquid separation valve is filled.
