Description
Technical field
The utility model relates to valve field, particularly about a kind of combined control valve of oil well head pipe-line system.The utility model is applicable to the control valve of water mixing oil-collecting oil field shaft mouth pipeline.
Background technology
The oil well head pipeline system is made up of many pipelines, and a well head comprises pipeline of oil production, water mixing pipeline, wax removal pipeline, level pressure gas relief line, sampling line, well-flushing pipeline etc.Every pipeline adopts independent distribution, and relevant by-pass valve control is installed, and realizes single control function.Its shortcoming is that installing space is big, the pipeline system complex structure, the operation and maintenance cost is high, leakage point is many, system's operational safety performance is poor.
Summary of the invention
The purpose of the utility model is the shortcoming that exists to prior art, provides that a kind of installing space is little, compact conformation, cost is low, leakage point is few, safety in operation is high multifunctional well head combination valve.
The technical scheme of the utility model comprises a combinaing valve body, mainly is to be shaped on tubing interface, cover interface tube, oil-out, water inlet, oil drain out on the said combinaing valve body, and oil drain out is communicated with oil-out; Connect delivery valve on the oil-out, connect draining valve on the oil drain out, connect water intaking valve on the water inlet; On the passage between tubing interface and the oil-out, be provided with inlet valve and in line check valve, the import of in line check valve is communicated with the outlet of inlet valve, on the passage between in line check valve and the inlet valve, is shaped on sample tap, on this sample tap sample valve is installed; On the passage between cover interface tube and the water inlet, be provided with casing valve and flushing valve, on the passage between casing valve and the flushing valve, be shaped on outfall and wax removal mouth, draining valve is installed on the outfall, connect atmospheric valve on the wax removal mouth; Passage between water inlet and the oil-out is provided with water mixing control valve and water inlet one way valve, and the outlet of water inlet one way valve is communicated with oil-out; Passage between oil-out and the outfall is provided with the casing pressure control valve, and the outlet of this casing pressure control valve is communicated with oil-out.
In above technical scheme, the casing pressure control valve is an one way valve.
In above technical scheme, oil pressure gauge is installed on the sample tap, water pressure gauge is installed on the outfall.
The utility model has the advantages that the by-pass valve control of the pipeline of oil production in the oil well head pipe-line system, water mixing pipeline, wax removal pipeline, level pressure gas relief line, sampling line, well-flushing pipeline is installed concentratedly in combinaing valve body; Many pipelines are become a pipeline; Simplify the pipeline installation system, reduced installing space, reduced manufacturing cost and maintenance cost; Reduce outer leak source, improved the security of system performance.
