Maintenance-free automatic blowdown straight-through type micro-resistance filter

Abstract

The invention discloses a maintenance-free automatic blowdown straight-through type micro-resistance filter and relates to the field of micro-resistance filters. A shell comprises a T-shaped cavity structure, a water inlet communicated with the interior of the T-shaped cavity structure is formed in one end of the shell, and a water outlet communicated with the interior of the T-shaped cavity structure is formed in the other end of the shell; The water inlet and the water outlet are located on the same horizontal line, an assembly hole is formed in the shell, and the maintenance-free automaticblowdown straight-through type micro-resistance filter further comprises a filter assembly arranged in the T-shaped cavity structure; a blind plate is arranged at the assembly hole of the shell. According to the technical scheme, the filtering efficiency is higher, a fluid flow channel is not changed in the filtering process, and turbulence is not additionally brought; A low-resistance environmentin the filter is guaranteed, and the efficient work of the water pump is guaranteed.

Description

technical field [0001] The disclosure of the invention relates to the field of micro-resistance filters, in particular to a maintenance-free automatic sewage discharge through-type micro-resistance filter. Background technique [0002] In the pipeline transportation system, a filter is installed in the pipeline to filter impurities in the fluid, so as to prevent pipeline blockage or equipment damage at the end of the pipeline caused by impurities. At present, the Y-type filter is the most commonly used in engineering, but it has the following disadvantages: [0003] 1. Due to the structural nature of the Y-type filter itself, the high-speed fluid is turbulent when it passes through the Y-type filter. If the filter is installed close to the water pump (power source), the turbulence brought by the Y-type filter will directly affect To the water pump, it is easy to cause uneven pressure at the suction end of the water pump, which will aggravate the cavitation phenomenon, great...

Problems solved by technology

[0003] 1. Due to the structural nature of the Y-type filter itself, the high-speed fluid is turbulent when it passes through the Y-type filter. If the filter is installed close to the water pump (power source), the turbulence brought by the Y-type filter will directly affect To the water pump, it is easy to cause uneven pressure at the suction end of the water pump, which will aggravate the cavitation phenomenon, greatly reduce the life of the water pump, and reduce the working efficiency of the water pump

[0004] 2. The blind plate (maintenance port) of the Y-type filter adopts a flange connection. During maintenance, the blind plate needs to be removed, and the filter must be taken out for cleaning. Professional staff are required for removal and installation, and the operation is cumbersome and time-consuming. Afterwards, the rubber gasket needs to be replaced again, and the Y-type filter has a certain height requirement during installation due to its special structural design, so it is necessary to use lifting equipment for the maintenance of the large-diameter Y-type filter;
