Description
Technical field:
The utility model relates to the antifreeze blocking air valve of used vent valve, especially packaged type in the oil recovery field, oil field.
Background technology:
Along with Oilfield developing, be connected with vent valve in order to improve the gas production rate at collar cover, by vent valve and pipeline natural gas is reclaimed.And present existing vent valve can only make the vent valve body cannot freeze stifledly, but fail to realize at oil inlet and oil return pipe companion hot arc, but fail to realize antifreeze purpose at oil inlet and oil return pipe companion hot arc, exist and easily freeze stifled problem, and loading and unloading are inconvenient, oil well venting work can not be carried out smoothly, influenced the ordinary production of oil well.
The utility model content:
In order to solve the problem in the background technology, the utility model provides a kind of packaged type antifreeze blocking air valve, and the antifreeze blocking air valve of this packaged type has whole process and is difficult for freezing stifled, easy to loading and unloading characteristics.
The technical solution of the utility model is: the antifreeze blocking air valve of this packaged type comprises ring set and switch main body, be connected with left connector on the switch main body, left side connector centre bore communicates with the switch main body inner air vent, the annular distance of left side connector communicates with ring set, left side connector right-hand member is communicated with the outer sebific duct of two ends belt lacing outward, be communicated with the interior sebific duct of two ends belt lacing in the outer sebific duct on the left connector, outer sebific duct and interior sebific duct right-hand member are connected with hybrid juction, sebific duct is connected with the oil inlet and oil return pipe in the hybrid juction, and the outer sebific duct of hybrid juction is connected with ginseng current journey.
Left connector right-hand member in the such scheme is outer to be connected by external conversion joint and outer sebific duct, and left connector right-hand member is outer to be connected by external conversion joint and interior sebific duct; Interior sebific duct right-hand member is connected with hybrid juction by the internal conversion joint.
The utlity model has following beneficial effect: the antifreeze blocking air valve of this packaged type is owing to take such scheme, be connected with ginseng current journey by outer sebific duct, outer sebific duct is given interior sebific duct companion heat, interior sebific duct is flat, makes not easy freezing of interior sebific duct, and the assurance whole process is not frozen stifled, and owing to adopt joint to connect, so easy to loading and unloading, oil well venting work can be carried out smoothly, guaranteed the ordinary production of oil well.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-switch main body among the figure, 2-ring set, 3-left side connector, 4-centre bore, 5-annular distance, the outer sebific duct of 6-, sebific duct in the 7-, 8-hybrid juction, 9-external conversion joint, 10-internal conversion joint.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, the antifreeze blocking air valve of this packaged type comprises ring set 2 and switch main body 1, be connected with left connector 3 on the switch main body 1, left side connector 3 centre bores 4 communicate with switch main body 1 inner air vent, the annular distance 5 of left side connector 3 communicates with ring set 2, left side connector 3 right-hand members are outer to be connected with the outer sebific duct 6 of two ends belt lacing by external conversion joint 9, be connected with the interior sebific duct 7 of two ends belt lacing by crossover sub 11 on the left connector 3 in the outer sebific duct 6, outer sebific duct 6 and interior sebific duct 7 right-hand members are connected with hybrid juction 8, interior sebific duct 7 right-hand members are connected with hybrid juction 8 by internal conversion joint 10, sebific duct is connected with the oil inlet and oil return pipe in the hybrid juction 8, and hybrid juction 8 outer sebific ducts are connected with ginseng current journey.
During actual the use, at first left connector 3 microcephalies are connected by switch main body 1 side of screw thread with venting valve rod lower end, again left connector 3 major parts and ring set 2 are welded together, left then 3 outer connections of connector are gone up external conversion joint 9, external conversion joint 9 is connected with joint on the outer sebific duct 6 again, be connected with crossover sub 11 on the connector 3 right-hand member microcephalies of a left side, crossover sub 11 be connected with joint on the interior sebific duct 7 again, outer sebific duct 6 right-hand members are connected with hybrid juction 8, interior sebific duct 7 right-hand members are connected with hybrid juction 8 by internal conversion joint 10, then the scene is connected pipe in the hybrid juction 8 with the oil inlet and oil return pipe, hybrid juction 8 outer tubes are connected with ginseng current journey, by clip two o'clock half clip short circuits on two o'clock half clip short circuits on the antifreeze blocking air valve of this packaged type and the well head big four are coupled together again, can normally use.Because of outer sebific duct 6 is connected with ginseng current journey, flow in the outer sebific duct 6 hot water is arranged, play the effect of companion's heat so just for interior sebific duct 7, reach whole process and be difficult for freezing stifled purpose, and the antifreeze blocking air valve of this packaged type is installed or unloaded from the oil inlet and oil return pipeline because of being easy to by hybrid juction 8, so the antifreeze blocking air valve of packaged type is easy to loading and unloading.
In sum, this movable freezing blocking air valve has whole process and is difficult for frozen block, loading and unloading side Just characteristics.
