Embodiment 1

[0032] Basic as attached Figure 2-Figure 3 Shown: a hydraulic self-tightening packing seal structure, the hydraulic self-tightening packing seal structure is a multi-stage packing seal structure, such as two-stage, three-stage or four-stage, etc. In this embodiment, it is a two-stage packing seal structure, Including the shaft 1, the first-stage packing sealing mechanism and the second-stage packing sealing mechanism, the first-stage packing sealing mechanism includes a primary stuffing box 7 and four rings of primary packing 12, the primary stuffing box 7 is set on the shaft 1, The primary stuffing box 7 is provided with a front sleeve 14 and a packing pressure ring 11 sleeved on the shaft 1, a fourth sealing ring 15 is provided between the front sleeve 14 and the primary stuffing box 7, and the front sleeve 14 is located at On the right side of the stuffing ring 11, the right end of the front sleeve 14 is in contact with the right inner wall of the primary stuffing box 7, a...

Embodiment 2

[0042] combine Figure 4As shown, the collection chamber 22 is connected with a collection pipe 16, and the collection pipe 16 is provided with a feedback detection control mechanism. The feedback detection control mechanism in this embodiment includes a controller, a flow meter 19 for detecting the leakage of high-pressure medium, and a A valve 18 for controlling whether the collecting pipe 16 is communicated and a pressure gauge 17 for detecting the hydraulic pressure of the high-pressure medium in the collecting pipe 16. The flowmeter 19 is connected with an alarm. The flow meter 19, the valve 18 and the pressure gauge 17 are all electrically connected to the controller. In this embodiment, the flowmeter 19 generally selects a volumetric flowmeter (because of its extremely small leakage, the flow can only be determined by collecting the leakage medium within a certain period of time), such as a rotameter whose model is LZXYB8GP-BA0-X4; 18 Generally, electric needle valves...

Embodiment 3

[0045] It is easy to understand that in this embodiment, the closing and opening of the valve 18 can be manually controlled according to the leakage detected by the flow meter 19 and the pressure detected by the pressure gauge 17 .

Abstract

The invention relates to the field of filler sealing, in particular to a hydraulic self-tightening filler sealing structure. The hydraulic self-tightening filler sealing structure comprises a shaft, afiller box with which the shaft is sleeved, filler located in the filler box and a pressing assembly for applying pressing force to the axial direction of the filler and further comprises a collecting cavity for collecting a high-pressure medium leaking from the position between the shaft and the filler. A pressing part for applying radial pressing force to the filler is arranged between the filler and the filler box, and power of applying the radial pressing force to the filler by the pressing part comes from hydraulic force of the high-pressure medium in the collecting cavity. By means of the scheme, the problem that the sealing performance of the filler away from a gland is poor is solved.

Description

technical field [0001] The invention relates to the field of packing seals, in particular to a hydraulic self-tightening packing seal structure. Background technique [0002] Packing seal is the main sealing form used in moving equipment. The principle of packing seal is to compress the packing through the gland or stuffing box. After the packing is under pressure, the packing weaving gap becomes smaller, thereby preventing the medium from leaking through the packing weaving gap. To achieve the effect of sealing. In addition, after the packing is under pressure, the pressure causes the packing to deform radially, the packing and the shaft are tightly combined, and the gap between the packing and the shaft becomes smaller, thereby preventing the medium from leaking axially through the gap between the packing and the shaft, and achieving the seal. Effect. [0003] The traditional packing seal structure such as figure 1 As shown, this figure shows a traditional two-stage pac...
