Abstract
The utility model provides a straight-through filter, which comprises an inlet water pipe, a sealing plate, a water inlet baffle, a shell, a shell flange, a flange cover plate, an outlet water pipe and a blow-off pipe. The utility model is characterized in that the inlet water pipe, the sealing plate and the water inlet baffle are welded on one end of the shell; the other end of the shell is welded with the shell flange and connected with the flange cover plate through a fastening bolt; the outlet water pipe is welded in the center of the flange cover plate and extends into the shell; and an end plate is welded on the end of the outlet water pipe; a plurality of small filter holes are evenly distributed on the end plate and the outlet water pipe extending into the shell; the blow-off pipe is arranged at the bottom of the shell; and a blow-off plug is arranged on the blow-off pipe. The utility model has the advantages that the structure is simple, the processing is convenient, the volume is small, the cost is low, the installation and the maintenance are convenient and rapid, the filtration effect is good, the straight-through filter is widely suitable for the pipeline systems of water supply, heating ventilation, air conditioning and heat supply.
Description
1, technical field
The utility model relates to a kind of filter, especially a kind ofly is used to supply water, HVAC, air-conditioning, the feedwater of Heat Supply Engineering, the through type filter of water return pipeline system.
2, background technology
When the installation and operation of the pipe-line system of water supply, HVAC, air-conditioning, Heat Supply Engineering, fall into the dirt in the pipe, or carry the sediment that enters pipe-line system, dirt etc. through current in the running, untimelyly filter and get rid of, will cause pipeline blockage or damage equipment and water appliance etc., and the pipeline of prior art filter has structure more complicated, processing trouble, cost height, volume heaviness, defectives such as overhauling trouble is installed.
3, utility model content
For solving above-mentioned the deficiencies in the prior art, the utility model provide a kind of simple in structure, easy to process, volume is little, cost is low, install and overhaul conveniently through type filter.
The technical scheme that its technical problem that solves the utility model adopts is: the through type filter is by water inlet pipe, shrouding, inlet damper, cylindrical shell, shell flange, flange plate, outlet pipe and blow-off pipe are formed, wherein, water inlet pipe, shrouding and inlet damper are in the end weldering system of cylindrical shell, the other end of cylindrical shell and shell flange welding, and be connected with flange plate by fastening bolt, be welded with outlet pipe at the flange plate center, outlet pipe extend into inner barrel, and be welded with end plate in its end, at end plate with extend on the outlet pipe in the cylindrical shell and be laid with the filtration aperture equably, be provided with blow-off pipe in the cylindrical shell bottom, and preparation there is the blowdown plug on blow-off pipe.During operation, current enter cylindrical shell from water inlet pipe through inlet damper, because current enter cylindrical shell through water inlet pipe sectional area sudden enlargement, water speed correspondingly reduces, like this, the sediment, the dirt that are carried in the current obtain precipitation, alluvial in cylindrical shell, and filter by the filter aperture, thereby reach the scrubbing effect.The effect that inlet damper is set is directly to impact end plate and cause distortion or obstruction filtration aperture behind water inlet pipe for fear of current.
When the utility model is installed, should add valve, not allow to be interrupted the occasion of water supply, also should establish bypass pipe for some at the interface of water inlet pipe and outlet pipe.
The beneficial effects of the utility model are, cylindrical shell is Welding Structure, and is easy to process, simple structure, and cost is low, and it is convenient that maintenance is installed, and good filtration effect can be widely used in supplying water, the filtration of the pipe-line system of HVAC, air-conditioning, Heat Supply Engineering.
4, description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure, 1, water inlet pipe, 2, shrouding, 3, inlet damper, 4, cylindrical shell, 5, fastening bolt, 6, shell flange, 7, flange plate, 8, outlet pipe, 9, filter aperture, 10, end plate, 11, the blowdown plug, 12, blow-off pipe.
5, the specific embodiment
Explain below doing with regard to 1 pair of through type filter of the present utility model of accompanying drawing below.
As shown in Figure 1, through type filter of the present utility model is by water inlet pipe (1), shrouding (2), inlet damper (3), cylindrical shell (4), shell flange (6), flange plate (7), outlet pipe (8) and blow-off pipe (12) are formed, wherein, water inlet pipe (1), shrouding (2) and inlet damper (3) are in the end weldering system of cylindrical shell (4), the other end of cylindrical shell (4) and shell flange (6) welding, and be connected with flange plate (7) by fastening bolt (5), be welded with outlet pipe (8) at flange plate (7) center, outlet pipe (8) extend into cylindrical shell (4) inside, and be welded with end plate (10) in its end, at end plate (10) with extend into to be laid with equably on the outlet pipe (8) in the cylindrical shell (4) and filter aperture (9), be provided with blow-off pipe (12) in cylindrical shell (4) bottom, and blowdown plug (11) arranged in the last preparation of blow-off pipe (12).During operation, current enter cylindrical shell (4) from water inlet pipe (1) through inlet damper (3), because current enter cylindrical shell (4) through water inlet pipe (1) sectional area sudden enlargement, water speed correspondingly reduces, like this, the sediment, the dirt that are carried in the current obtain precipitation, alluvial in cylindrical shell (4), and filter by filter aperture (9), thereby reach the scrubbing effect.The effect that inlet damper (3) is set is directly to impact end plate (10) and cause distortion or obstruction filtration aperture (9) behind water inlet pipe (1) for fear of current.
Claims (1)
1, a kind of through type filter is by water inlet pipe, shrouding, inlet damper, cylindrical shell, shell flange, flange plate, outlet pipe and blow-off pipe are formed, it is characterized in that: water inlet pipe, shrouding and inlet damper are in the end weldering system of cylindrical shell, the other end of cylindrical shell and shell flange welding, and be connected with flange plate by fastening bolt, be welded with outlet pipe at the flange plate center, outlet pipe extend into inner barrel, and be welded with end plate in its end, at end plate with extend on the outlet pipe in the cylindrical shell and be laid with the filtration aperture equably, be provided with blow-off pipe in the cylindrical shell bottom, and preparation there is the blowdown plug on blow-off pipe.
