Description
Technical field
The utility model belongs to defroster, particularly relates to the antifreeze well head manifold valve of a kind of ring-type self-heat conserving group.
Background technology
In the existing oil recovery production technology, production tree is housed, controls various pipelines, to adapt to the requirement of production with valve at the oil well mouth., each valve crisscross at existing pipeline installed dispersion, floor space is big, production management is difficult, and the problem that workload is big, the stolen phenomenon is serious generally adopts flow process well head combination valve at present.But this flow process well head combination valve heat-preserving anti-freezing adopts electrically heated method always, has both wasted electric energy, has brought unnecessary potential safety hazard to production again, influences the ordinary production of producing well.
Summary of the invention
The purpose of this utility model provides a kind of system's self-heating of utilizing valve body is carried out the antifreeze well head manifold valve of the ring-type self-heat conserving group of self-heat conserving, has solved that existing ring-type head valve disperses on the oil field, not manageability, complicated operation, the phenomenon of freezing-proof theft-proof not.
The antifreeze well head manifold valve of ring-type self-heat conserving of the present utility model group is to have designed many valves and the multitube paths constitutes on valve body.Side at valve body is provided with total stop valve, is provided with oil pressure gauge connection and casing pressure meter connector at the opposite side of valve body, is provided with the oil pipe connecting leg in the front of valve body, the back is provided with the oil return tube connector; On valve body, be provided with single current stop valve, valve discharging gas under certain pressure, get oil pressure valve and get the casing pressure valve, below valve body, be provided with oil pipe and cover pipe connected pipe.
Further improve as the utility model, described total stop valve, single current stop valve, valve discharging gas under certain pressure, get oil pressure valve and get casing pressure valve and oil pipe tube connector, oil return tube connector, come oil pipe and cover pipe connected pipe all to have the conduit in the valve body to link up mutually.
The antifreeze well head setting of ring-type flow process, be according to oil field part oil well viscosity of crude height, low, the not water mixing of pressure, adopt the oil-collecting of ring-type single tube return metering room characteristics and in conjunction with existing ring-type well head, valve on the oil field disperse, not manageability, complicated operation, the present situation of freezing-proof theft-proof not.The antifreeze well head manifold valve of ring-type self-heat conserving of the present utility model group, it is integrated in one former many valves, and utilize system's self-heating that valve body is carried out self-heat conserving, thereby overcome the shortcoming of in the past twining the heat tape insulation, not only safety but also power saving has that volume is little, easy for installation, safe antitheft, system's insulation, an advantage such as quick easy to maintenance.

Fig. 2 is the vertical view of the antifreeze well head manifold valve of ring-type self-heat conserving of the present utility model group.
The specific embodiment
The antifreeze well head manifold valve of ring-type self-heat conserving of the present utility model group is to have designed many valves and the multitube paths constitutes on valve body 1, and be provided with total stop valve 2 in a side of valve body 1, opposite side at valve body 1 is provided with oil pressure gauge connection 3 and casing pressure meter connector 4, be provided with oil pipe connecting leg 5 in the front of valve body 1, the back is provided with oil return tube connector 6, on valve body 1, be provided with single current stop valve 7, valve discharging gas under certain pressure 8, get oil pressure valve 9 and get casing pressure valve 10, below valve body 1, be provided with oil pipe 11 and cover pipe connected pipe 12.And total stop valve 2, single current stop valve 7, valve discharging gas under certain pressure 8, get oil pressure valve 9 and get casing pressure valve 10 and oil pipe tube connector 5, oil return tube connector 6, come oil pipe 11 and cover pipe connected pipe 12 all to have the conduit in the valve body 1 to link up mutually.
Installation and operating principle are:
During installation, oil-in among the figure and production tree are produced pipe link to each other, oil return pipe links to each other by welding manner with the oil return pipeline, and natural gas tieback mouth links to each other with production tree casing pressure mouth, can adopt different connected modes according to different production trees.If do not reclaim natural gas, the level pressure stop valve can be closed and get final product.Confirm above-mentioned steps connect correct after, with single current stop valve 7, get oil pressure valve 9, oil pressure gauge connection 3, oil return tube connector 6 and close, sequence number valve discharging gas under certain pressure 8, casing pressure meter connector 4 are opened, can go into operation; During sampling, open oil pressure gauge connection 3 and connect oil sample at this place; When surveying oil pressure, open oil pressure gauge connection 3 in this place's pressure measurement; Open oil return tube connector 6 when getting casing pressure and connect the table pressure, the intact back of pressure valve-off at this place.
Valve discharging gas under certain pressure, the opening pressure of setting when dispatching from the factory is 0.8Mpa, and when promptly sleeve pipe air pressure was more than or equal to 0.8Mpa, natural gas entered the oil return pipeline, and casing pressure is during less than 0.8Mpa, and valve discharging gas under certain pressure is closed automatically, prevents that crude oil from flowing backwards.
Valve discharging gas under certain pressure pressure is adjusted: be rotated counterclockwise the level pressure valve rod, opening pressure is reduced, the level pressure that turns clockwise valve rod can make opening pressure increase.Generally speaking, be rotated counterclockwise and one week of level pressure valve rod can make opening pressure reduce to 0.75Mpa from 0.8Mpa, minimum opening pressure is 0.6Mpa, promptly is rotated counterclockwise level pressure valve rod 21/4 circle, when transferring to 0.6Mpa, can not turn down, otherwise crude oil can flow backwards again.Otherwise turn clockwise one week of valve discharging gas under certain pressure, can make opening pressure increase to 0.9Mpa from 0.8Mpa, two all pressure become 1Mpa, and closing dead level pressure valve rod pressure-bearing is 6Mpa.
