ISO Tank bottom valve connector thread cleaning device

Abstract

The invention discloses an ISO Tank bottom valve connector thread cleaning device which comprises a sleeve capable of being rotated by torsion. A circular die in thread fit with an ISO Tank bottom valve connector is fixed to the inner circumferential wall of the sleeve, a middle shaft extending towards an inner hole of the ISO Tank bottom valve connector is fixed to the inner end wall of the sleeve, and a positioning sliding sleeve matched with the inner hole of the ISO Tank bottom valve connector in a sleeved and inserted mode is axially installed on the middle shaft in a sliding mode. A baffle ring for blocking the positioning sliding sleeve is arranged at the outer end of the middle shaft, and a compression spring is arranged between the inner end of the sleeve and the positioning sliding sleeve. Under the condition that the bottom valve thread connector is not detached, the residual material can be cleaned, and the damaged thread can be tapped while the residual material is cleaned, so that time and labor are saved, and the carrying is convenient.

Description

technical field [0001] The invention relates to the technical field of ISO Tank containers, in particular to a device for cleaning the screw threads of an ISO Tank bottom valve interface. Background technique [0002] Due to the continuous action of the residue, hardening and accumulation of the residual liquid during unloading, the bottom valve interface of ISOTANK has accumulated a large amount of residual hardened material, which makes it difficult to connect the threaded interface of the bottom valve during unloading, and the forced butt joint will cause thread deformation. At present, there are three main solutions to the above problems: [0003] 1. If the residual material is serious or the wire teeth are deformed, the solution is to replace the threaded interface of the bottom valve, which has the problems of troublesome disassembly operation, time-consuming work and high cost; [0004] 2. If the residual material is light or there is no thread deformation, the botto...

AI Technical Summary

Problems solved by technology

[0003] 1. If the residual material is serious or the wire teeth are deformed, the solution is to replace the threaded interface of the bottom valve, which has the problems of troublesome disassembly operation, time-consuming work and high cost;

[0004] 2. If the residual material is light or there is no thread deformation, the bottom valve interface is removed, and the residual material is cleaned after soaking with chemical reagents. There are problems of troublesome disassembly operation, time-consuming, high cost, and endangering the health of operators;

[0005] 3. If the residual material is light or there is no thread deformation, remove the bottom valve interface and clean the residual material after high-temperature baking. There are problems of troublesome disassembly operation, time-consuming, high cost, and the gas generated by high temperature is harmful;
