The downside of the screw stem passes through a sealing device on top of the insertion plate box to connect with a nut (5) in the middle of top side of the insertion plate. The utility model has the advantages of wide adjustable range of resistance, high adjusting precision, good balancing effect, less adjusting workload, long life-span and convenient examination.
Description
Technical field
The utility model relates to a kind of dedusting pipe network with adjustable wear-resisting resistance balance device.
Background technique
In the dedusting pipe network system, because the airduct of same system is an interconnective integral body, thereby must follow each branch road resistance balance rule, when the structural type of air-line system, line size once determining, under certain air quantity effect, the air quantity of each section distributes automatically by the resistance balance rule.When designing and calculating, calculate, can cause system's actual air volume to distribute and different design without resistance balance.Certainly we also can distribute air quantity by regulating air-valve, but so just make the blast of non-index circuit unnecessary again.Has realistic meaning so when designing and calculating, consider the resistance balance of each loop.
Current technical grade environmental protection requires just higher with the dedusting pipe network to the resistance balance between each branch line.But existing environmental protection resistance balance device, because all there are some defectives in the problem of structure.For example notification number is the Chinese patent " dedusting pipeline resistance balance device " of CN2481949Y, and its main defective is that resistance is non-adjustable.And for example the patent No. is 01249526 Chinese patent " board-like resistance balance device ", and mentality of designing is the same with push-pull valve, has just increased wear-resisting structure, adopts this equipment, after system builds up, relies on Field adjustment resistance of pipe system balance fully, and debugging work load is very big.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of dedusting pipe network with adjustable resistance balance device, and this balace weight can be regulated the dedusting pipe resistance easily.
The technological scheme that the utility model adopted is: comprise by short tube and radially be fixed in the balace weight that the inner core in its chamber is formed that the short tube two ends are provided with the flange that connects cleaning shaft; The adjustable resistance device is housed on balace weight, the plate that it is provided with the plate box and is positioned at its chamber, and drive the man-operated mechanism of the notch of plate turnover balace weight with change inner core sectional area; Man-operated mechanism is made up of with the screw rod that links to each other of middle part with it handwheel, and the bottom of this screw rod links to each other with the nut thread of plate upper center after passing the seal arrangement on plate box top.
The utility model compared with prior art has following major advantage:
1. owing to increased inner core and adjustable throat sheet, adopt the mode of inner core coarse adjustment intercalary plate fine setting to regulate resistance, so regulation range is wide, the degree of regulation height, debugging work load is little, and is applied widely.
2. inner core and plate adopt high-abrasive material, and anti-wear effect is good, owing to increased plate, even cause the inner core wearing and tearing owing to service time is long, still can regulate the pipeline flowing resistance by regulating plate, have prolonged working life.
3. equipment can effectively prevent to leak out by adopting welding and sealing gasket sealing means.
4. adopt flange to connect easy access and replacing between equipment and the cleaning shaft.
Description of drawings
