Abstract
Steel welding straight-through filter, main body is the valve body of a horizontal type, is equipped with the filter cylinder that is covered with filter bores in valve body; Valve body side welding one adapter, adapter extend in valve body, and end welds together with filter cylinder again; Body base has a circular hole, and circular hole is welded with silk braid, has screwed blowoff valve in silk braid.The utility model adopts welding procedure, saves the cost of flange, bolt, pad, saves huge amounts of material resource.Reduce casting process to the pollution of air.The smooth blowdown of valve interior wall is unobstructed, and the large resistance of filter area is low.Filtering foreign outside filter cylinder, blowdown of being more convenient for.Valve body should be incubated, decrease valve body loss thermic load.The utility model adopts with pipeline connected mode and welds, and makes pipeline safer, more energy-conservation, more stable, more efficient.
Description
Technical field
The utility model relates in heat supply, air-conditioning, HVAC and feedwater use, and the filter of blow-off line medium foreign material, is specifically related to a kind of steel welding straight-through filter.
Background technology
Prior art: filter (y-type filter) is Flange joint, the general filtering foreign material of filter type are in filter cylinder, and cylinder inner area is little again, and make filter resistance very large, Y type strainer valve volume is large, and installation site is limited.Y-type filter can not accomplish online blowdown and backwash, generally during blowdown medium or equipment must be closed down.The foreign material got rid of can not be transported to appointed place, can only scene be discharged to.Connected mode is also Flange joint, during for HVAC industry, because special construction is unfit to do insulation, wastes a large amount of thermic load.
Summary of the invention
The purpose of this utility model be to provide a kind of structure simple, manufacture simple, performance is good, the life-span is long, blowdown is simple, simple to operate, online blowdown, have backwashing function, and device chamber volume is large, the welding straight-through filter of lower resistance.
The purpose of this utility model is achieved through the following technical solutions:
Steel welding straight-through filter, main body is the valve body of a horizontal type, is equipped with the filter cylinder that is covered with filter bores in valve body; Valve body side welding one adapter, adapter extend in valve body, and end welds together with filter cylinder again; Body base has a circular hole, and circular hole is welded with silk braid, has screwed blowoff valve in silk braid.
Also have a circular hole at body top, circular hole is welded with observation panel.
Twist in observation panel and be connected to plug.
Blowoff valve is connected with blowoff valve conduit.
Valve body two pipe nipple adopts with outer pipeline connecting mode and welds.
The utility model steel straight-through filter is manufactured by steel-pipe welding, adopts welding procedure, without casting method, adopts steel-pipe welding to form, reduce casting process to the pollution of air.Being connected connected mode with pipeline is also adopt welding manner, saves the cost of flange, bolt, pad, saves huge amounts of material resource.Owing to adopting steel pipe manufacture, the smooth blowdown of valve interior wall is unobstructed, and the large resistance of filter area is low, and lightweight is little.Because valve body volume is large, the long filter area of filter cylinder is large, adopts direct-passing mode can accomplish that resistance is very low.Due to adopt outside filtering type structure, namely filtering foreign outside filter cylinder, blowdown of being more convenient for.Without the need to the equipment of closing down and valve-off when blowdown and backwash, make device context more clean.Owing to have employed straight-through Welding Structure, valve body should be incubated, decrease valve body loss thermic load.Due to steel pipe manufacture, to bear pressure large, the life-span same with pipeline, and the welding manner of employing, freeze proof, booster, rolloff, earthquake, mud-rock flow, make pipeline safer, more energy-conservation, more stable, more efficient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 plug, 2 observation panels, 3 valve bodies, 4 adapters, 5 filter cylinders, 6 silk braids, 7 are to silk, 8 blowoff valves, 9 blowoff valve conduits.
Detailed description of the invention
See Fig. 1, steel welding straight-through filter, main body is the valve body 3 of a horizontal type, is equipped with the filter cylinder 5 that is covered with filter bores in valve body 3.Welding one adapter 4 of valve body 3 side, adapter 4 extend in valve body 3, and end welds together with filter cylinder 5 again.Have a circular hole bottom valve body 3, circular hole is welded with silk braid 6, screwed blowoff valve 8 in silk braid 6, blowoff valve 8 is connected with blowoff valve conduit 9, connects flexible pipe and dirt can be discharged to assigned address, be unlikely to be discharged to scene, be convenient to blowdown.Also have a circular hole at valve body 3 top, circular hole is welded with observation panel 2, twist in observation panel 2 and be connected to plug 1, plug 1 can be opened as required and observe valve body 3 internal state.Described valve body 3 liang of pipe nipples 4 adopt with outer pipeline connecting mode and weld.
The utility model valve body and adapter are all select steel pipe manufacture, and first valve body hydraulic pressure is closed up, filter cylinder is welded in adapter, the adapter and the other end that are welded with filter cylinder is taken over and is directly welded on valve body.Welding upper observation panel, joint, loads onto blowoff valve, blowdown connection again.Finally to screw on plug.
Medium in pipeline passes through steel welding straight-through filter, the filtering foreign in medium outside cartridge filter.Can open blowoff valve during blowdown online goes out foreign material external, is discharged to formulates position by adapter and connecting hose.After blowdown completes, blowoff valve cuts out, if heat supply pipeline or air conditioning piping can carry out backwash, close filter early gate, open blowoff valve, utilize return pipe medium device cylinder and Filter cartridge can be carried out backwash, the foreign material be attached in filter cylinder bore are removed by backwash.
Regularly to open blowoff valve external filtering foreign material drain.
