AI Technical Summary
When disassembly, mechanical seals are prone to jamming the fastener due to thread grooves, which leads to inconvenience in disassembly. Especially in the case of kettle use, it is difficult to easily remove the fastener due to the small installation groove space.
A self-balanced mechanical seal is designed. By setting a spring and a push ring on the arc block, the second spring is used to push the push ring so that the fastener can be successfully withdrawn from the thread groove and avoid jamming.
It realizes convenient disassembly of fasteners, avoids jamming problems, and improves the convenience of operation.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical seals, in particular to a self-balancing mechanical seal for a kettle. Background Art
[0002] A mechanical seal is a balanced shaft sealing device for rotating machinery. Its installation direction varies according to different application environments. For example, when a mechanical seal is used in a reactor, it is usually installed perpendicular to the ground plane.
[0003] When the mechanical seal is assembled, there are two arc blocks fixed together by fasteners at the bottom. When the fastener is removed, the rear end of the fastener passes through one arc block and is embedded in the threaded groove of another arc block, and the installation groove of one arc block for placing the fastener is smaller. When the fastener is rotated and disassembled to the end, the notch of the threaded groove will jam the fastener, so the fastener needs to be taken out manually. However, due to the small space in the installation groove, the fastener cannot be taken out conveniently, and it can only be rotated continuously and tipped down, which is more troublesome.

[0006] A self-balancing mechanical seal for a kettle comprises a support body and a sealing gasket, wherein the sealing gasket is embedded in the upper surface of the support body, a No. 1 arc block is provided on the surface of the support body and on one side located below, and a No. 2 arc block is provided on the surface of the support body and on the other side located below, mounting grooves are provided on the surface of the No. 1 arc block and near both ends, a fastener is embedded in the interior of the mounting groove, a push ring is movably embedded in the interior of the mounting groove, and a No. 1 spring is provided on the upper surfaces of the No. 1 arc block and the No. 2 arc block.
[0007] Preferably, a socket is provided on the inner rear surface of the installation groove, an extrusion groove is provided on the inner rear surface of the installation groove and located at the periphery of the socket, a movable groove is provided on the inner upper and lower surfaces of the extrusion groove, a guide rod is fixedly installed inside the movable groove, and a No. 2 spring is sleeved on the surface of the guide rod.
[0008] Preferably, the extrusion groove is annular, and the push ring is movably embedded in the extrusion groove.
[0009] Preferably, threaded holes are provided on both end surfaces of the second arc-shaped block, and the rear end of the fastener passes through the insertion hole and is embedded in the threaded groove.
[0010] Preferably, sleeve blocks are fixedly mounted on the upper and lower surfaces of the rear end of the push ring, and the sleeve blocks are sleeved on the surface of the guide rod.
[0011] Preferably, one end of the No. 2 spring is fixed to the sleeve block, and the other end of the No. 2 spring is fixed to an inner end surface of the movable groove.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] In the utility model, by arranging the No. 1 arc block and the push ring to cooperate with each other, when the fastener is removed, the push ring will be squeezed into the extrusion groove and the No. 2 spring will be compressed during the installation of the fastener. Therefore, when the fastener is removed, as the rear end of the fastener is continuously withdrawn from the thread groove of the No. 2 arc block, the No. 2 spring will push the push ring, so that the push ring pushes the fastener, so that the rear end of the fastener can be conveniently withdrawn from the thread groove without getting stuck.
