Technical Field

The utility model relates to the technical field of pipeline engineering, in particular to a cargo system separation device for a chemical tanker.

Background

Bulk chemical carriers require the design of effective insulation for the cabin layout and piping systems because of the reactivity, contamination, etc. that may exist between the different cargo loads. The conventional single marine sliding type duplex blind flange is used, for example, the prior published marine sliding type duplex blind flange with application number of CN202010926155.3 only has one isolation flange, which can not meet the requirement of 'effective isolation' in the rule, therefore, the prior art generally uses a detachable short pipe for separation, and comprises three parts of a short pipe with flanges at two ends and two duplex blind flanges, the short pipe is used for connecting when a pipeline system is communicated, the short pipe needs to be detached and stored when the pipeline system is separated, the original pipeline is sealed by the duplex blind flange, in the process of detaching and assembling, a plurality of workers are needed to complete the matching, the workload is large, after detaching and assembling are completed, the detached parts need to be properly kept, the work of workers is inconvenient, and the short pipe or the duplex blind flange needs to be completely detached in the process of detaching and assembling, a partition valve needs to be installed outside the short pipe, otherwise, the leakage of chemicals is easy to cause, the production cost is improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a cargo system separating device of a chemical tanker, which can complete effective isolation of pipelines without being completely disassembled by utilizing an integrated design and has simple and efficient operation.

In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a chemicals ship cargo system separator, the symmetry is provided with two pair blind flange, pair blind flange is equipped with through-hole end and blind end, and the through-hole end is provided with the through-hole, the constant diameter screw of the same overall arrangement is all seted up along excircle edge to through-hole end and blind end, the spout that is in constant diameter with the screw is seted up to pair blind flange both sides, spout parallel symmetry sets up, the screw of through-hole end and blind end is connected at the spout both ends, the rigid coupling has connect through-hole's connecting pipe between the through-hole end of two pair blind flanges. The goods of the chemical tanker have reactivity, when the pipeline needs to be communicated, the through hole ends of the duplex blind flange are butted with the pipeline flanges at two ends, the through hole ends of the duplex blind flange are fastened with the pipeline through bolts, the pipelines at the two ends are communicated through a middle connecting pipe, when the pipeline system needs to be cut off, the bolts are loosened, the duplex blind flange is moved along the sliding groove, the blind end is butted with the two ends of the pipeline, the blind end of the duplex blind flange is fastened with the pipeline through the bolts, the management system is cut off, the two duplex blind flanges are integrally designed, the purpose of effective isolation is achieved, meanwhile, the operation of workers is simpler and more convenient, and the working efficiency of the workers is improved.

And a handle is fixedly connected between the two duplex blind flange. The handle is arranged between the two duplex blind flange plates, when the switching operation is carried out, the operation of moving the duplex blind flange plates can be completed by pulling the handle, the operation is simple, and the time and the labor are saved.

The handle is made of a steel tube. The handle made of the steel pipe is welded between the two duplex blind flange plates, and the steel pipe is simple in structure, convenient to manufacture and low in cost.

And a grounding device is arranged between the screw hole and the bolt. Inflammable gas is easy to gather on a chemical ship, and static electricity on a pipeline can be led out in time through the grounding device, so that the phenomenon that fire accidents are caused by the fact that sparks generated by the static electricity ignite the inflammable and explosive gas is avoided.

The duplex blind flange and the connecting pipe are made of stainless steel. The stainless steel has the characteristics of corrosion resistance and high temperature oxidation resistance, is suitable for a chemical pipeline system, avoids the leakage of the partition device, and prolongs the service life of the device.

Compared with the prior art, the utility model has the following advantages:

adopt the integrated design, need not to demolish "effectively keeping apart" that can accomplish the pipeline completely, need not install the problem of isolation valve in the nozzle stub outside when having avoided original demolising completely, reduced manufacturing cost and the risk that the chemicals leaked, and need not deposit the part of pulling down separately, improved the space utilization of boats and ships, single dismouting work can be accomplished, has lightened workman's work burden, has reduced the human cost.
