Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
The utility model is by production tree ontology 1, packing box 3, preventer core 5, control valve 7, manometric module 8, screw-type method
Sealing element, the connector of orchid 10,11 7 kinds of components of pipe plug and different specification size are composed.1 upper end of production tree ontology is
Cylindrical body, lower end are hubbed flanges；The periphery held on it, it is big, symmetrical that front and rear, left and right is machined with two small two
Vertical plane；Six channels being mutually communicated inside it, six passways be located at its up and down, front and rear, left and right six
In a plane.Passway above it is connected with bolt and nut 2 and packing box 3；Passway below passes through band cervical approach
Orchid is connected with the tubing head on well head；The passway on its front and back two sides, uses stove bolt nut 4 respectively, respectively fills one and be only inserted it
In, the preventer core 5 of opposite switch；Bolt and nut 2, gasket ring 6 and stay bolt spiral shell are used in the passway on its left and right two sides respectively
Mother 9, is fixedly connected with the control valve 7 of both wings and its components in outside.
Packing box 3 is the important component for cooperating sucker rod work, is carrying out dynamic sealing to the sucker rod of reciprocating motion
Meanwhile having the function of automatic angle adjusting correction, the service life of packing box 3 and helical packing 3-7 can be extended by a relatively large margin.
