Resistance balance valve

Abstract

The invention discloses a resistance balance valve. The resistance balance valve comprises a pipe body, an anti-blocking measuring device, a fixed arc valve plate, a movable arc valve plate, a movable valve box and an adjusting handle. Flanges are arranged at the two ends of the pipe body. The anti-blockage measuring device comprises a dust removal device, a settling chamber communicated with the dust removal device, and an air induced pipe communicated with the settling chamber. The dust removal device and the settling chamber are located inside and outside the pipe body respectively. The left end of the movable arc valve plate is located in the movable valve box, the right end of the movable arc valve plate serves as a working part and is located in the pipe body, the two sides of the movable arc valve plate are movably connected to a support arranged on the pipe body, and the left end of the movable arc valve plate is connected with the adjusting handle through a ball screw. By means of the anti-blocking measuring device, air pressure in a pipeline can be regularly or irregularly detected, and a basis is provided for system adjusting; and by means of a pipeline section dial gauge, the sectional area of the pipeline is more visual and convenient to adjust, good concentricity is achieved for arc passageways of the valve plates and the outer pipe body, and pipeline abrasion caused by the bias current phenomenon is reduced.

Description

technical field [0001] The invention relates to the resistance balance of pipe network design, in particular to a resistance balance valve. Background technique [0002] The centralized dust removal system often includes dozens or even hundreds of dust collection hoods. The pipe network is branched, with a large number of branch pipes. Parallel pipes are formed between the branch pipes. The balance of air volume and resistance needs to be considered in the design of the pipe network, that is, the air volume and resistance of each branch pipe. The distributed air volume is consistent with the designed air volume. The fluid flow resistance loss between the parallel branch pipes is basically equal, and the relative difference in the resistance loss value should not exceed 10%, otherwise the dust removal system will have many problems and even lose its function. For example: the air volume of some hoods is too small to achieve the effect of dust source control; the air volume o...

The fluid flow resistance loss between the parallel branch pipes is basically equal, and the relative difference in the resistance loss value should not exceed 10%, otherwise the dust removal system will have many problems and even lose its function

For example: the exhaust air volume of some vacuum hoods is too small, and the effect of dust source control cannot be achieved; the air volume of some vacuum hoods is too large, and a large amount of materials are sucked away; the wind speed of some branch pipes is too small, and dust settles in the pipeline, causing pipeline blockage; The wind speed of some branch pipes is too high, causing serious wear and tear on the pipes
