Furthermore, handles are arranged on two sides of the pressing cap, so that force can be applied to the pressing cap conveniently.
Further, go up packing and lower packing upper end and be the rectangle structure setting, it is the back taper structure setting with lower packing lower extreme to go up the packing, realizes the sealed leak protection of dual ladder.
Furthermore, threaded connection is adopted between the pressing cap and the upper packing box and between the upper packing box and the lower packing box, the threaded connection mode is convenient for independently disassembling and replacing wear parts, the centralizer is in threaded connection with the lower part of the lower packing box, the fixing cap is in threaded connection with the lower part of the centralizer, and the connector is fixedly connected with the fixing cap through screws.
Furthermore, the centralizer is made of polytetrafluoroethylene.
Adopt above-mentioned structure the utility model discloses the beneficial effect who gains as follows: this scheme prevents inclined to one side formula well head sealer adopts two packing structures to set up and has strengthened sealed effect, goes up the packing simultaneously and all adopts the structure setting of rectangle upper end and back taper lower extreme with lower packing, and the sealed leak-proof technological effect of dual ladder all can be realized to each packing, and the threaded connection mode between centralizer and the lower packing box can be realized preventing inclined to one side adjustment.
