Abstract
The utility model discloses a gas-liquid self-controlled gas-separating packet used on a gathering pipeline of an oil producing well in petroleum industry, which avoids the phenomenon of oil inlet of a gas pipeline and ensures the normal operation of equipment. The gas-liquid self-controlled gas-separating packet can also be applied to the branch line and the main line of civil gas-transmission pipelines for gas-water separation. The gas-liquid self-controlled gas-separating packet comprises a body, wherein a gas-transmission pipe is arranged at the upper part of the body, a gas-separating packet inlet and a gas-separating packet outlet are arranged at the lower part of the body, a liquid-level self-controlled device is installed in the body, and therefore the inlet of oil liquid or water in the gas-transmission pipe is avoided. The actions of discharging gas in the presence of the gas and automatically closing in the presence of no gas are realized, the oil inlet of the gas-transmission pipe is avoided, the workload is reduced, and the normal operation of heating equipment is ensured.
Description
Technical field
The utility model relates to the gas-liquid separation device of petroleum industry oil well, and particularly a kind of gas-liquid autocontrol divides gas bag, can be applicable on the oil-gas gathering and transportation pipeline of oil well, avoids the tracheae line phenomenon of oil-feed to occur, guarantees the normal operation of equipment.Also can be applicable to civilian gas transmission line, the enterprising promoting the circulation of qi moisture of main line from.
Background technology
Dividing gas bag is to carry out the modal equipment of gas-liquid separation in the oil well production, and it is that Crude Oil Transportation is heated that isolated gas can be supplied with the oil well heating furnace.Existing branch gas bag is a size of utilizing gas vent, and control divides the liquid level in the gas bag indirectly, avoids fluid to enter by the by-pass valve control on the adjusting appendix, and is simple in structure, and the situation that fluid enters the tracheae line often appears in regulation and control inconvenience.After fluid enters the tracheae line, stop up appendix, cause warming-up device out of service, crude oil does not flow, back pressure height, whole system cisco unity malfunction.This just can return to normal production after just must stopping work such as well pipeline purging, blowdown, brings a lot of unnecessary trouble and workloads to work.From security consideration, the branch gas bag of oil well can't use electric energy, so the problems referred to above never solve for many years.The production scene of oil well needs a kind of mechanical, the branch gas bag that can control liquid level automatically.
Summary of the invention
The purpose of this utility model provides a kind of gas-liquid autocontrol and divides gas bag, avoids occurring the situation of tracheae line oil-feed, reduces workload, guarantees the normal operation of equipment.
For reaching above-mentioned purpose, can use the technical program: a kind of gas-liquid autocontrol divides gas bag to comprise body, and upper part of body is provided with appendix, and the bottom is provided with the import of branch gas bag and divides the gas bag outlet, the liquid level self-con-tained unit is housed in body, avoids fluid or water to enter in the appendix.
Compared with prior art, the utlity model has following useful effect: when the utility model divides when having the oil gas fluid-mixing to flow in the gas bag import, because of the body cavity of resorption is full of suddenly, rate of flow of fluid reduces.Under the gravity effect, Oil-gas Separation, tolerance is normally given vent to anger under the control of appendix valve.When not having fluid or appendix not to be filled in minute gas bag import, divide the interior gas of gas bag under the effect of pressure reduction, still continue to flow to the appendix direction, last cavity pressure reduces, then the liquid level in the cavity of resorption rises, and the ball float that promotes autocontrol valve rises, and closes the outlet of autocontrol valve, stop fluid to flow out, reach the purpose of automatic control liquid level.When the gassiness fluid is flowed through the branch gas bag once more, divide gas-liquid separation in the gas bag, the liquid level in the cavity of resorption descends, and autocontrol valve is opened automatically, and gas flows out once more, returns to normal production.The liquid that enters branch gas bag epicoele simultaneously flows back to cavity of resorption once more under the gravity effect.Realized that gas gives vent to anger, the gas transmission line oil-feed is avoided in the effect that no gas is closed automatically, has reduced workman's workload, guarantees the normal operation of warming-up device.Be applied to civilian gas transmission line, the enterprising promoting the circulation of qi water of main line separates automatically, can guarantee the pure of gas in the gas transmission line.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model autocontrol valve.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to Fig. 1, a kind of gas-liquid autocontrol divides gas bag to comprise body 2, and the top of body 2 is provided with appendix 1, and the bottom is provided with branch gas bag import 6 and divides gas bag outlet 5, and the liquid level self-con-tained unit is housed in the body 2.The liquid level self-con-tained unit comprises remittance liquid funnel 3 and autocontrol valve 4, and autocontrol valve 4 is installed in the below of remittance liquid funnel 3, the remittance liquid mouth of the corresponding remittance of its outlet liquid funnel 3.The periphery of remittance liquid funnel 3 and the inwall of body 2 are fixed together, and body 2 is divided into epicoele 8 and cavity of resorption 7.Referring to Fig. 2, autocontrol valve 4 comprises valve seat 9, valve body 11 and ball float 12, and ball float 12 places in the valve body 11, and valve seat 9 is installed in the top of valve body 11; Valve body 11 is sieve shape cylindrical shells, completely filters pore 10 at cylindrical shell and tube base fabric, and gas enters the epicoele 8 of branch gas bag from filter pore 10.
In concrete the use, when having mixed air-flow body to flow through in minute gas bag import 6, because of the cavity of resorption 7 of minute gas bag is full of the flow velocity reduction of fluid minute gas bag cavity of resorption 7 in suddenly.Under the gravity effect, Oil-gas Separation, gas is entered by the filter pore 10 of valve body 11, is advanced in the outlet of valve seat 9 in the epicoele 8 of branch gas bag, then through appendix 1 output.Gas divides the liquid level in the gas bag relatively stable under the control of the valve on the appendix 2, and ball float 12 is in the bottom of valve body 11, normal separation gas under the effect of gravity.When mixing the inflow of air-flow body in minute gas bag import 6, divide the interior gas of gas bag under the effect of pressure reduction, still continue to flow to appendix 1, then divide the liquid level in the gas bag to rise, the ball float 12 that promotes in the autocontrol valve 4 is up, cooperate the outlet of closing gas with valve seat 9, stop liquid to flow in the epicoele 8 that divides gas bag, reach the purpose of automatic control liquid level.When the gassiness fluid is flowed through the branch gas bag once more, divide gas-liquid separation in the gas bag, the liquid level in the cavity of resorption 7 descends, and autocontrol valve 4 is opened automatically, and gas flows out once more, returns to normal production.Enter liquid in the epicoele 8 under the gravity effect, flow back to once more in the cavity of resorption 7.
