An anti-tampering device and a valve using the device

Abstract

The invention discloses an anti-tampering device for a valve and the valve. The valve body of the valve has a passage opening, and the anti-theft device includes: an anti-theft buckle, the anti-theft buckle includes an anti-theft buckle body, a pulling part, a tear part, an elastic buckle and a limit surface, and the pulling part can be locked through the tear part. Tearfully connected to the body of the anti-theft buckle; there is a limit contour and an anti-theft cover for the hanging platform; a limit groove is set on the passage opening; when in use, the anti-theft cover is connected to the passage opening, and the elastic buckle is buckled into the hanging platform along the limit contour and connected to the hanging platform The matching of the limit groove makes the relative position of the anti-theft cover and the valve body limited. The invention can be installed and opened without using tools, and can effectively prevent the materials stored and transported in the container from being stolen in practical application.

Description

technical field [0001] The invention relates to a tamper-proof device for a valve, in particular to a tamper-proof device for a composite intermediate bulk container (IBC). Background technique [0002] Composite intermediate bulk container (IBC) is commonly known as ton packing plastic container, and its composition structure is divided into inner tank and frame. Composite intermediate bulk containers (IBC) can be reused many times, and the advantages reflected in filling, storage and transportation can significantly reduce costs. The bottom of the composite intermediate bulk container (IBC) is equipped with a discharge valve to facilitate the removal of residues in the container. However, in order to prevent the storage and transportation of materials from being stolen during transportation, an anti-tampering device needs to be installed on the valve. [0003] The valve anti-tampering device of existing composite intermediate bulk container (IBC) is usually provided with ...

AI Technical Summary

Problems solved by technology

The disadvantage of this valve anti-theft opening device is that the installation of the anti-theft strip is troublesome, the installation efficiency is very low, and it is very difficult; to open the container, it is necessary to use a tool or use a large force to destroy the anti-theft strip; Weak, easy to damage the cover body, affecting the use of the entire device of the valve; the anti-theft cover has high manufacturing requirements and costs, the anti-theft cover and the anti-theft strip are integrated, and the anti-theft strip is separated from the anti-theft cover when it is opened, and the anti-theft cover cannot be reused, resulting in waste

In addition, since the anti-theft strip is easy to lose after detaching from the anti-theft cover, it brings difficulties in cleaning the surrounding environment

[0005] Other anti-tampering devices, such as a welded PE bag flange on the valve body, due to the fixed size of the welding head on the flange side, the anti-theft buckle must be assembled after welding, such an operation is more complicated and easy to miss
