Embodiment Construction
[0016] like Figure 1 to Figure 3 The anti-shock filter shown includes a cavity 1, the left side of the cavity 1 is provided with a filter inlet 4, and the right side of the cavity 1 is provided with a filter outlet 5 coaxial with the filter inlet 4 One side of the cavity 1 is provided with a filter element 2, and the other side of the cavity 1 is fixed with an annular air bag 3 for absorbing water hammer pressure and thermal expansion pressure in the pipeline through a fixing device. The cavity 1 The upper end is provided with loam cake 14. The filter element 2 is a barrel-shaped filter element, and the wall of the barrel of the filter element 2 is provided with several through holes. The fluid device of the present invention integrates filtration and anti-shock. An annular airbag and a filter element are arranged in the filter cavity, which saves space and does not require a separate space for installation. It is installed inside the pipeline without sealing elements and ha...

The invention discloses a water-attack resisting filter. Provided is a fluid device, which is good in absorption effect, small in space occupation, and less in investment and gathers filtering and water-attack resistance into an entirety. A filter core and an annular air bag for absorbing the water-attack pressure and thermal expansion pressure in a pipeline are arranged in a cavity of the water-attack resisting filter, wherein the annular air bag is arranged on a fixed support. The fixed support is arranged on a cavity or a cover board of the filter. The annular air bag comprises a gas filled tube, which is provided with a valve, an inflation inlet, and a pressure gauge. The water-attack resisting filter can be installed on a pipeline in front of a pump and a flowmeter of a liquid distribution system. The filter can filter impurities, eliminates water attack, and effectively prevents thermal expansion and cold contraction of liquid in the sealed pipeline against damaging the filter. The filter is small in space occupation and less in investment, and can be widely applied to the fields of chemical industry, petroleum, food, and transportation of liquid mediums, such as water.
Description
technical field [0001] The invention belongs to the field of fluid machinery, in particular to an anti-shock filter. Background technique [0002] In the process of liquid pipeline transportation, on the one hand, in order to protect the equipment or the quality of transportation, it is usually necessary to install a filter; The sharp rise will damage the equipment, and it is generally necessary to install a water hammer eliminator. In the prior art, the filter and the anti-shock eliminator are two independent devices, which are respectively installed on the pipeline. It takes up a lot of space, and the anti-shock eliminator installed on the branch pipe is not effective in eliminating water hammer. Therefore, it is necessary to design a space-saving and anti-shock filter with good absorption effect. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a fluid dev...
