Abstract

The utility model relates to a pipeline filter filtering the impurities in the fluid medium in the pipeline in order to protect the safe operation for valves, and is provided to resolves the problem that the welding slag and oxidized metal in fluid medium in the pipeline are accumulated at the valve so as to affect the smooth valve operation and cause the abrasion of the seal surface of the valve. The technical proposal is that a pipeline filter is disposed between a pipeline (5) and a valve. The pipeline filter is likened to a four-way pipe joint, and composed of a short communicating pipe(1) and an inclined short filter pipe(2) mutually intersected and communicated with the short communicating pipe(1). The utility model is characterized in that two ends of the short communicating pipe (1) are matched with the pipeline and valve in the diameter. A partitioning plate (3) is arranged inside the short filter pipe (2) in a radial direction and seems to stop the fluid or gas medium with a mesh. Upper nozzles (21) at two sides of the short filter pipe (2) are enclosed and lower nozzles (22) are welded or made into a seal flange. The utility model is mainly used to filter the impurities in the production pipelines in the electric plants and the chemical engineering enterprises so as to protect the normal production operation of the valves, which is suitable for the filtration of the fluid medium in the pipelines of the other industries.

Description

Pipeline filter sundries

(1) technical field: the utility model is the foreign material that the filter pipe inner fluid carries, and belongs to protection valve safe operation field.

(2) background technique: at present in chemical industry, thermal power generation corporations, pipeline connects liquid storage casing, valve, carries liquid, vapour material to be found everywhere.In mesohigh pipeline connect box, valve, mostly adopt welding, can not close mistake such as the foreign material of exempting to have welding slag, iron filings and stay in casing and the pipeline; Also have normal phase to use or stop reusing after a period of time, casing and inner-walls of duct all can have etching of oxides to come off in casing and pipeline, above-mentioned these foreign material with flow of liquid when the valve, will be trapped in the valve, make valve closing not tight, or be interrupted the valve of opening and open difficulty, valve wearing and tearing because of the corrosion of foreign material productive set causes, influence safe operating life, make valve not reach the spreadable life with regard to needing replacing or repairing, bring loss to safe operation, generation can cause the accident when serious.In sum, the foreign material in the pipeline have directly influenced the safety switch and the working life of valve, closely have influence on the safe operation of whole system.

(3) summary of the invention:

Technical problem to be solved in the utility model: welding slag, iron filings and other foreign material in the in-service pipeline are not filtered out when advancing valve, and the protection valve does not cause switch difficulty and wearing and tearing because of foreign material, prolongs valve working life; The foreign material that filter can regularly clean again, and the assurance system is normal, safe operation.

The technological scheme that solves the problems of the technologies described above: the liquid in pipeline, the vapour material enters the pipeline end before the valve, the filter sundries install pipes, its profile is similar to union cross, comprise circulation short tube and crossing with it, intercommunication becomes the filter thing short tube at certain tilt angle to form, the short tube two ends bore that it is characterized in that circulating is complementary with pipeline that is connected and valve aperture, intersect with it in filter thing short tube at certain tilt angle along internal diameter size and be shaped on like for stopping up circulation liquid, the dividing plate of the band mesh of vapour material, the upper orifice at filter thing short tube two ends is shut, lower nozzle is made row's thing mouth, and row's thing mouth welds dead or makes flange and seal.

The beneficial effects of the utility model: 1, liquid, vapour material enter on the preceding pipeline of valve in the pipeline because pipeline filter sundries are contained in, liquid, vapour material must be filtered sundries through pipeline before advancing valve, because the dividing plate of band mesh is housed in the pipeline filter sundries, when the foreign material that bring with liquid, vapour material are crossed the dividing plate of band mesh, just can effectively filter out, protect the smooth switch of valve, again because of valve flashboard place no-sundries, make valve not easy to wear, prolonged the safe operation of system; 2, because the filter thing short tube diameter of pipeline filter sundries greater than circulation short tube diameter, though the dividing plate of band mesh is arranged in the filter thing short tube, can not influence the flow of quality in the pipe, guaranteed the normal operation of producing; (3) because the filter thing short tube in the pipeline filter sundries intersects certain tilt angle with the circulation short tube, the foreign material that filter on the dividing plate of band mesh in the filter thing short tube are easily assembled to row's thing mouth, make mesh unimpeded, guaranteed the normal operation of producing, filter in the thing short tube because of being inserted into the dividing plate of mesh simultaneously, therefrom take out operation during easy access and clean.

(4) description of drawings:

Fig. 1 is radially sectional structure schematic representation of pipeline filter sundries;

Fig. 2 is that pipeline filter sundries are installed and used schematic representation.

Five, embodiment:

With reference to Fig. 1, Fig. 2, pipeline filter sundries adopt steel pipe weldering system or cast steel to be processed into product.Profile is similar to union cross, it comprises circulation short tube 1 and becomes the filter thing short tube 2 at certain tilt angle to form with its crossing intercommunication, in the time of on being used in the high pressure pipeline, circulation short tube 1 two-port is made bevel for welding or is made flange-interface, be complementary with pipeline 5 that is connected and valve 6 bores, if be contained between low pressure line and valve, the two-port of circulation short tube can be made into screw thread or flange-interface, be complementary with its tractor tool, with the diameter of the filter thing short tube 2 at 1 one-tenth certain tilt angle of runner pipe diameter greater than circulation short tube 1, in pipe, be equipped with seemingly to stopping up circulation liquid along internal diameter size, the dividing plate 3 of the band mesh of vapour material, dividing plate 3 is inserted in the plugboard trough of filtering on thing short tube 2 inwalls 4, the upper orifice 21 at filter thing short tube 2 two ends is shut, and lower nozzle is made row's thing mouth 22.These filter sundries are used between mesohigh pipeline, the valve, and row's thing mouth welds dead or makes flange and seal, and low pressure can be used thread ending cover.

Pipeline filter sundries are installed between pipeline and valve when using, should select for use the two ends bore of the circulation short tube 1 of pipeline filter sundries to be complementary with the bore of pipeline 5 that is connected and valve 6, no matter pipe-line is probably perpendicular, its row's thing mouth should be downward, is connected at or flange dead with the weldering of pipeline, valve and then just can uses.After using a turn(a)round, the row's of opening thing mouth 22 is extracted dividing plate 3 out, after superincumbent welding slag, metallic oxide and foreign material are detained in removing, reload the dead row of weldering thing mouth and just can use again.
