Description
Technical field：
The present invention relates to mobile liquid logistics transportation apparatus field, it is particularly suited for the pressure of IBCS or packing material
Release device.
Background technology：
IBCS or packing material are mainly made up of container, boom hoisting, forklift groove and other reinforcers, can be by hanger
Lifting, forklift lift to carry movement, and stacking storage can be put into and multimodal transport is realized in container, by its safety, soon
The advantage such as prompt, portable, reusable, using widely in dangerous material liquid transporting industry.Hold to meet intermediate bulk
Device or the related design standard of packing material, IBCS or packing material overhead vapor space domestic demand set pressure relief device
Normal safe to ensure IBCS or packing material is transported.
Pressure relief device is a kind of safety guard, and it is in normally off in normal operation, when medium-sized
Pressure rise in bulk container or packing material is automatically turned on more than setting, and intermediate bulk is ensured by outside discharge medium
The use safety of container or packing material.
Normal pressures release device is typically from fall lift type spring safety valve is opened wide, and its structure is general by valve body, spring, lid
Plate, sealing device etc. are constituted, and steam vent is carried on its valve body.Its operation principle is as shown in Figure 3：Body base interface can pass through
Flange or screw thread are connected with container or packing material, and its is easily disassembled, and theftproof performance is poor；Under normal condition, spring passes through
The elastic force of itself compresses cover plate and valve body, and cover plate is sealed with valve body part by sealing device, when pressure in container or packing material
Power is raised, and the pressure value thrust downward more than spring, and the now sealing between cover plate and valve body is opened, too high pressure
Thus outwards discharge, after pressure value reduction in container or packing material, its pressure value thrust downward less than spring is now covered
Sealing is compressed between plate and valve body by the pressure clamp force of spring.This kind of safe releasing device structure reliability, but its structure ratio
More complicated, heavier-weight, its appearance and size is difficult to reduce.Its setting Opening pressure value mainly depends on the pressure of spring, works as needs
, it is necessary to change spring or adjustment spring pressure value when changing its setting Opening pressure, its later stage working service is relatively costly and more
Change cumbersome, generally require professional person to complete.Steam vent is outer without safety guard, when its pressure outwards discharges, easily
To periphery, operating personnel damage.
The content of the invention：
The invention aims to overcome the shortcomings of the above, there is provided a kind of bulk container that is easy to operate, improving therapeutic effect
Or packing material pressure relief device.
The purpose of the present invention is achieved through the following technical solutions：A kind of bulk container or packing material pressure relief device,
Including valve body, body base interface can be connected by screw thread with container or packing material, there is what is along the circumferential direction arranged on valve body
Steam vent, the valve body outside where steam vent is provided with the sealing ring of specific elasticity.
Further improvement of the present invention is：Setting Opening pressure value mainly depends on that sealing ring possesses circumferencial direction and tightens power
With the size or quantity of its steam vent.
Further improvement of the present invention is：Steam vent and sealing ring outside are provided with protective cover.
Further improvement of the present invention is：Protective cover installs fixation, valve body by being threaded the fastener of pretension
Top is provided with screw rod, and fastener is arranged on screw rod, and the end of screw rod is provided with anti-theft hole.
Further improvement of the present invention is：Anti-theft hole is mutually fixed by flexible apparatus with container or packing material.
Further improvement of the present invention is：Flexible apparatus are steel wire rope, chain.
The present invention has advantages below compared with prior art：Simple structure of the present invention, lighter in weight, latus rectum same case
Under, it is smaller that its appearance and size can be designed；Present invention setting Opening pressure value mainly depends on that sealing ring possesses circumferencial direction and stretches tight
The size or quantity of clamp force and its steam vent, its Opening pressure value adjustment only need to change and possess different circumferencial directions and tighten the close of power
Seal, or change the size or quantity of its steam vent when making, its sealing ring is changed conveniently and cost is relatively low, and general staff is with regard to energy
Operation is completed；Its steam vent of the invention and sealing ring outside are provided with protective cover, and too high pressure can be avoided to direct out release, subtract
It is few that periphery operating personnel are damaged；Anti-theft hole in the present invention can by steel wire rope, chain or other flexible apparatus with
Container or packing material are mutually fixed, it is ensured that the theftproof performance of its safe releasing device.

Specific embodiment：
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below by the skill in the embodiment of the present invention
Art scheme is clearly and completely described, it is clear that described embodiment is a part of embodiment of the invention, rather than whole
Embodiment.The element and feature for describing in one embodiment of the invention can be with one or more other embodiment party
The element and feature shown in formula are combined.It should be noted that eliminating for purposes of clarity, in explanation unrelated to the invention
, the expression and description of part known to persons of ordinary skill in the art and treatment.Based on the embodiment in the present invention, this area
