A split packing gland

Abstract

The invention discloses a split-type packing gland, comprising a left splicing part and a right splicing part symmetric to the left splicing part, wherein U-shaped connecting pieces are symmetrically arranged at the two ends of each of the left and right splicing parts, and a U-shaped opening is arranged in each U-shaped connecting piece; and the left splicing part can be spliced with the right splicing part correspondingly, the U-shaped connecting pieces on the two splicing parts are mutually overlapped, and the U-shaped openings mutually coincide. The split-type packing gland has the beneficial effects that the two splicing parts can be axially limited under the condition that no fixed bolts are mounted; the split-type packing gland can be directly cast and meet the mounting demands without being further machined, and the production procedures are effectively simplified; after the two splicing parts are spliced, the inner diameter of each U-shaped opening is adjustable, the limitation on the diameter of bolts when the fixed bolts are mounted is omitted, and the mounting step is greatly facilitated; the fixed bolts only need to rotate or slide towards the outside of the U-shaped openings, so that the fixed bolts can be disassembled, and the disassembly efficiency is effectively improved.

Description

technical field

[0001] The invention relates to a packing gland, in particular to a split packing gland. Background technique

[0002] The packing gland is usually used to compress the packing of the sealing liquid to ensure the tightness between the packing and the packing cavity and packing sleeve. During the operation of the pump, as the flexibility, expansion and wear resistance of the packing decrease, the packing gland needs to be adjusted frequently. When the packing gland is adjusted to a certain degree or fits with the packing cavity, the worn packing must be added or replaced.

[0003] Such as figure 1 and figure 2 As shown, the traditional packing gland is an integral type, and the axial movable space of the packing gland is very small. When it is damaged and needs to be replaced, the nearby bearing parts must be disassembled, which is time-consuming and laborious. When the axial position is limited, disassembly and The difficulty of installation is particula...

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0027] Such as Figure 5 and Figure 6 As shown, the center of the left splicing piece 100 is provided with a semicircular pressure ring 110, the right splicing piece 200 is symmetrical in shape with the left splicing piece 100, and the center of the right splicing piece 200 is provided with a semicircular pressure ring 120. The circular pressure rings 110 and 120 are symmetrical in shape and can cooperate with each other to form a complete circular pressure ring.

[0028] Both ends of the left splicing piece 100 are symmetrically provided with U-shaped connecting pieces 120, 130, wherein the U-shaped connecting piece 130 is flush with the lower surface of the left splicing piece 100, and along the thickness direction of the U-shaped connecting p...
