Problems solved by technology

[0002] At present, the openings of the pipelines of ships at sea are generally open. Since there are many floating objects or impurities on the sea, the floating objects or impurities are easy to enter the pipeline through the opening of the pipeline and cause blockage. Therefore, it is necessary to set a filter screen at the opening of the pipeline to Isolation of impurities
[0003] In the current CB*623-80 standard for suction filters, there is no clamp ring for filters with a diameter of more than 125mm. The net is prone to loosening or even slipping during the use at sea. If it is not found in time, it will cause large economic losses.

Abstract

The invention relates to the technical field of filter screens, and discloses a pipeline filter screen which comprises a filter screen body used for being arranged at an opening of a pipeline in a sleeving mode and a plurality of fastening assemblies. The multiple fastening assemblies are sequentially arranged on the end surface of one end of the filter screen body; and each fastening assembly comprises a fixing piece fixed to the end face of one end of the filter screen body, a bolt and a nut which is in threaded connection with the bolt, wherein the fixing piece is provided with a through hole for the bolt to penetrate through, the bolt comprises a head and a screw rod used for abutting against the outer side face of the pipeline, and the head of the bolt and the nut are located on the two sides of the fixing piece. The pipeline filter screen can be suitable for a large-drift-diameter pipeline and is firmly clamped on the pipeline.

Description

technical field [0001] The invention relates to the technical field of filter screens, in particular to a pipeline filter screen. Background technique [0002] At present, the openings of the pipelines of ships at sea are generally open. Because there are many floating objects or impurities on the sea, the floating objects or impurities are easy to enter the pipeline through the opening of the pipeline and cause blockage. Therefore, it is necessary to set a filter screen at the opening of the pipeline to Isolate impurities. [0003] In the current CB*623-80 standard for suction filters, there is no clamp ring for filters with a diameter of more than 125mm. The net is prone to loosening or even slipping during use at sea. If it is not found in time, it will cause large economic losses. Therefore, it is necessary to design a filter that can be firmly clamped on the pipeline for a filter with a diameter of more than 125mm. Contents of the invention [0004] The purpose of ...
