The model utility content
The utility model technical problem to be solved is to provide a kind of anti-leak stuffing box assembly of avoiding cross pollution.
The technological scheme of the utility model is following: a kind of anti-leak stuffing box assembly; Comprise flange plate, stuffing box group, throttling box and two pull bars up and down; Be the stuffing box group between said flange plate and the throttling box; The center of said flange plate is provided with center hole; And in this center hole, being provided with central shaft, each stuffing box in the said stuffing box group is provided with center hole, also is provided with circle water injection hole, an oil hole and upper and lower two tie rod holes on the said stuffing box; Said central shaft passes each stuffing box and the center hole of throttling box in the stuffing box group; Be provided with labyrinth ring between said throttling box and the central shaft, the two ends up and down of the inboard of said throttling box are respectively equipped with a counterbore, and wherein upper connecting rod is fixed in the counterbore of throttling box upper end after passing the upper end, stuffing box upper connecting rod hole of flange plate respectively; Said lower link is fixed in the counterbore of throttling box lower end after passing the lower end, stuffing box lower link hole of flange plate respectively; Be respectively equipped with inner seal ring and exterior seal ring on the stuffing box of the inside and outside both sides of one circle water injection hole of said stuffing box, said oil hole and upper and lower two tie rod holes all are positioned on the stuffing box in the exterior seal ring outside, and wherein said oil hole is between upper and lower two tie rod holes.
Adopt technique scheme; With being set on the stuffing box in the stuffing box assembly, inside and outside two-layer seal ring avoids leaking; And oil hole and upper and lower two tie rod holes all are arranged on the stuffing box in the exterior seal ring outside; Also can avoid high pressure oil and gas to get into the water the inside even leakage phenomenon takes place, the phenomenon of cross pollution takes place.
In technique scheme, the hole heart of the hole heart of said upper and lower two tie rod holes and the center hole of stuffing box is on same straight line.
In technique scheme: the hole heart in said upper connecting rod hole departs from the elongation line 1-3mm of connecting line of the hole heart of the center hole of said lower link hole and stuffing box.Can avoid like this when stuffing box is formed the stuffing box group, the both sides up and down of stuffing box being done anti-, cause whole stuffing box assembly not use.
In technique scheme: install for ease, the hole heart in said upper connecting rod hole departs from the elongation line 2mm of connecting line of the hole heart of the center hole of said lower link hole and stuffing box.
Beneficial effect: the utility model is reasonable in design, simple in structure, implement easily, can prevent heads, avoid taking place the phenomenon of cross pollution.
