Embodiment Construction

[0027] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but only to illustrate the essence of the technical solutions of the present invention.

[0028] figure 1 A structural perspective view of an IBC 100 with a liner 10 is shown, partially cut away to show the liner 10 , the flange 20 connected to the liner 10 , and the valve 30 . Such as figure 1 As shown, the IBC 100 generally has a base, four side panels, and a cover panel (not shown). When the IBC 100 is used to transport liquid goods, the liquid goods are usually contained in the liner bag 10, and then the liner bag 10 is put into the container 100 for transportation. At the bottom of the container there is a discharge channel...

Abstract

The invention discloses a connecting mechanism of a flange and a valve, and a liner and a container using the connecting mechanism of the flange and the valve. The flange is connected with the medium-sized bulk container liner bag in a welded mode; the valve comprises a valve body and a valve tail portion used for connecting with the flange. The connecting mechanism comprises a connecting device and a sealing device, wherein the connecting device comprises a plurality of flange barbs installed on the flange and a plurality of valve barbs installed on the valve tail portion. When the connecting mechanism is in use, the flange barbs of the flange and the valve barbs of the valve tail portion are hooked together tightly to achieve the connection of the valve and the flange. The sealing device comprises a sealing ring, wherein the sealing ring exerts a force on the valve and the flange, and the force can be divided into an axial component force along the axial direction of a valve passageway of the valve and a radial component force along the radial direction of the valve passageway of the valve. When the connecting mechanism is in use, the problem that the connection of the medium-sized bulk container liner bag flange and the valve drops can not occur and the connecting mechanism has the advantages of reducing rejection rate in production and manufacturing.

Description

technical field [0001] The invention relates to an intermediate bulk container for logistics transportation, in particular to a liner bag in the intermediate bulk container. Background technique [0002] During the transportation of food, medicine, chemicals, etc., some liquids are corrosive or have anti-pollution requirements, so it has become common to use plastic liner bags to hold liquids. Due to the inherently limited strength of plastic liners, these liners are often placed in Intermediate Bulk Containers (IBCs) and have a drain device that allows the liquid to drain. And in order to control the discharge of liquid, a valve can be assembled under the plastic liner bag. The valve is connected with the plastic inner bag by the flange welded on the plastic inner bag. In the process of liquid transportation, the strength of the connection between the valve and the flange on the plastic liner bag is not enough and it is easy to fall off. In addition, when the viscous liq...
