Brief description of the drawings
Fig. 1 is the utility model decomposition texture schematic diagram；
Fig. 2 is the unidirectional rotating disk decomposition texture schematic diagram of the utility model.
Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described further：
As shown in figure 1, this angle correction oil and gas wellhead sealer has sealed compartment 1, list is socketed with the top of sealed compartment 1
To rotating disk 2, unidirectional rotating disk 2 can only be rotated to a direction, and the center of unidirectional rotating disk 2 offers the light rod aperture for being inserted into polished rod
3, offer packing guide hole 4 in the avris of light rod aperture 3.In one embodiment of the present utility model, the top of sealed compartment 1 can be with
It is circular hatch, ratchet 21 is evenly distributed with the outer of circular hatch, unidirectional rotating disk 2 is socketed on circular hatch, in list
Stage clip 23 and thimble 24, the one end of thimble 24 and stage clip 23 are equipped with cavity, cavity to leaving to have in handle 22, handle on rotating disk
It is connected, the other end is withstood on ratchet 21.There is circular cover 27 in the middle of unidirectional rotating disk 2, light rod aperture 3 and packing guide hole 4 are opened in
In circular cover 27.In order to preferably convey packing, packing guide hole 4 is connected with spirality packing delivery chute 25 downwards, in spiral
Leave and sharp lead tooth 26 in the end of shape packing delivery chute 25.Packing refers to the material for being wrapped in and being sealed on polished rod, such as belt
Deng, unidirectional rotating disk 2 in packing feeding packing guide hole 4, will be rotated, lead tooth 26 and drive packing to enter along spirality packing delivery chute 25
Sealed compartment 1 is interior and is wrapped on polished rod, plays a part of sealing, it is possible to prevent oil from being flowed from the space on polished rod Yu periphery
Go out.
The bottom of sealed compartment 1 is connected through conduit 5 with spherical connector 6, and polished rod can pass through conduit 5 and the bottom of spherical connector 6
The first through hole 7 in portion, spherical connector 6 socket-connects with the ball cover type connecting seat 8 of lower section, the inside of ball cover type connecting seat 8 have with
The spherical ball recess 9 for matching in the outside of spherical connector 6, covers one layer of sealant on ball recess 9, and sealant is selected to be had
The material of certain flexibility is served as, and can such as select teflon seal layer, such spherical connector 6 to be located in ball recess 9
When being in contact with sealant, can be rotated in certain angle, and the sealing of connection can be kept all the time.In actual fabrication, the
The diameter of one through hole 7 is greater than the diameter of the second through hole 10 of the bottom of ball cover connecting seat 8, so can guarantee that spherical connector 6 with
When certain angle is connected with ball cover type connecting seat 8, through the polished rod and first through hole 7 of the through hole 10 of first through hole 7 and second
