Abstract
The utility model discloses a kind of auto-compensating double-sealing Stuffing box, end plate is arranged installation plectane, install on plectane and opposite opened filler casing is set, rear seal filler is set in filler casing, rear seal filler front fills the first Gland, the rear portion of the first Gland arranges gas collection chamber, the front portion of filler casing arranges the gas source connector communicated with gas collection chamber, the internal surface of the first Gland is step-like, step is arranged front sealing filler, front sealing filler fills the second Gland; First Gland is connected with filler casing by the first bolt, and the second Gland is connected with the first Gland by the second bolt, and the first bolt, the second bolt are all set with butterfly spring.The utility model is rational in infrastructure, and before and after being formed, twice packing seal structure, arranges gas collection chamber, the gas collection of leakage can be got up between twice packing seal, discharges, do not pollute the environment through gas source connector.
Description
Technical field
The utility model relates to technical field of mechanical, particularly a kind of auto-compensating double-sealing Stuffing box.
Background technique
Existing packing seal structure, the friction between bar axle and Stuffing box makes bar and Stuffing box wear and tear simultaneously, sealability can be caused to decline, cause and can not seal time serious, and reaction gas easily leaks from Stuffing box, and befouling environment, to affect workman healthy.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, without the auto-compensating double-sealing Stuffing box of gas leakage.
Technical solution of the present utility model is:
A kind of auto-compensating double-sealing Stuffing box, comprise end plate, end plate is arranged installation plectane, it is characterized in that: install on plectane and opposite opened filler casing is set, rear seal filler is set in filler casing, rear seal filler front fills the first Gland, the rear portion of the first Gland arranges gas collection chamber, the front portion of filler casing arranges the gas source connector communicated with gas collection chamber, the internal surface of the first Gland is step-like, step is arranged front sealing filler, front sealing filler fills the second Gland; First Gland is connected with filler casing by the first bolt, and the second Gland is connected with the first Gland by the second bolt, and the first bolt, the second bolt are all set with butterfly spring.
First Gland, the second Gland all adopt split type.
The utility model is rational in infrastructure, and before and after being formed, twice packing seal structure, arranges gas collection chamber, the gas collection of leakage can be got up between twice packing seal, discharges, do not pollute the environment through gas source connector; Select butterfly spring, be that Gland has pretightening force always, even if also can filler be compressed when filler has wearing and tearing, do not affect sealing effect.Gland can adopt split type, and mounting or dismounting are convenient, and centering is good, can not produce rub with main shaft.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the lateral plan of Fig. 1.
