The on-line filter can be directed arranged on a main pipe line for filtering mediums. When the on-line filter is used for cleaning pipes, the operating device is switched, and the valve core is rotated by 90 DEG for cleaning the pipes and draining sewage. The utility model has the advantages of convenient operation, continuous filtering operation of pipeline mediums, easy maintenance, easy replacing of the filtering nets, and one machine with multiple functions.
Description
The utility model relates to universal machine valve technology, belongs to the improvement of pot strainer structure, is applicable to long-distance transport pipes or needs to play a kind of filter medium on the general industry pipe line of pigging.
Existing long-distance transport pipes are particularly carried the high pipeline that contains wax crude oil and non-purified natural gas medium, and the general industry pipeline, along with the growth of service time, all require pigging.But the existing both at home and abroad at present pot strainer that constitutes by valve body, screw nut bolt, O type rubber ring and filter screen, equal direct piggings, want pigging that by-pass line and line valve must be installed on pipeline, when needs pipeline media filtration, need block the line valve of bypath system, open and be positioned at filter, forward and backward stop valve; When needs cleanings pipeline or when changing screen pack, need close and be positioned at the forward and backward stop valve of filter, open the line valve of bypath system.So just bring on a pipeline several valves will be installed simultaneously, constitute the pipeline bypath system and finish.So just exist difficulty be installed, operate cumbersome, the uneconomic problem of cost height.
The purpose of this utility model provides a kind of online filter of energy pigging, only needs to switch manual station, and rotational valve core 90 is spent, and just can finish the purpose of pipeline media filtration and cleaning pipeline, reaches operation rapidly, effect easy to install.
The utility model can pigging pot strainer by left and right valve body, spool, last lower valve shaft, mozzle, key, bottom, side cover, sliding bearing, axle sleeve, pad, pressure ring, O type rubber ring, nut screw, bolt, manual station, valve seat supporting, seat ring, spring, inside and outside filter screen, filtering agent and blowdown apparatus constitute.
Concrete structure is by Fig. 1, Fig. 2 explanation, and left valve barrel (1) couples together with nut bolt (43,44) with right valve barrel (3), seals by O type circle (6); The same mozzle of spool (7) (9) welding, the top of spool (7) is connected with last valve shaft (10) by key (11); Last valve shaft (10) outsourcing sliding bearing (22) realizes passing through with the smooth rotation ， And of right valve barrel (8) sealing of O type circle (18,19) and axle sleeve (20) realization and right valve barrel (8); Pad (21) is used to adjust the size gap between valve shaft (10) and the axle sleeve (20); In order to prevent that valve shaft (10) and axle sleeve (20) are subjected to pressure medium and fly out, ad hoc meter pressure ring (15) and hexagon socket head cap screw (14) are to push down; Operator (16) is connected with last valve shaft (10) by key (17) with right valve barrel Lian Jie ， And by nut, double-screw bolt (12,13).The bottom of spool (7) has hole (B, C), and the bottom is supported on the bottom (39) by lower valve shaft (28); Lower valve shaft (28) outsourcing sliding bearing (29) is realized the smooth rotation with right valve barrel (8).Pad (38) is used to adjust the size gap between lower valve shaft (28) and the bottom (39); Bottom (39) is realized and the sealing of right valve barrel (8) by O type circle (40), is realized the connection of same right valve barrel (8) with nut, double-screw bolt (41,42); Blowdown apparatus (27) is installed in the indentation D place, bottom of right valve barrel (8), valve seat supporting (2,24) is pressed on the spool (7) seat ring (5,23) by spring (3,26), the sealing And that realizes seat ring (5,23) same spools (7) realizes that by O type circle (4) valve seat supports the sealing of (2) same left valve barrel (1), by the sealing of O type circle (25) realization valve seat supporting (24) with right valve barrel (8).Spool (7) connects by the same outer leaching net of screw (32) (30), Inner filter net (33), filtering agent (31); Right valve barrel (8) connects by nut, double-screw bolt (35,36) same side covers (34), realizes the sealing of same right valve barrel (8) by O type circle (37).
The utility model can pigging the material of each parts of pot strainer be: seat ring (5,23) is with enhanced polytetrafluoroethylene or all kinds of rubber mass compression moulding.O type circle is that rubber can be bought to market, sliding bearing (22,29) applies polytetrafluoroethylene (PTFE) with stainless steel wire mesh ， And and makes on the surface of net.Filtering agent (31) adopts all kinds of inorganic matters.All the other each parts can be selected steel for use according to the requirement of filter medium, carry out processing and fabricating on machine tool, and wherein spool (7) will be made on the ball machining tool.
When from the medium of upstream side by the gap between spool (7) and mozzle (9) after, through Inner filter net (33), after the filtration of filtering agent (31) and outer leaching net (30), flow to the downstream, dirt enters the indentation D place of right valve barrel (8) by the hole (B, C) of spool (7) bottom.When blowdown or cleaning pipeline, by operator (16) rotational valve core 90 degree, outer leaching net this moment (30) is over against side cover (34), mozzle (9) is over against last, the downstream, because valve seat supporting (2,24) by spring (3,26), O type circle (4,25), seat ring (5,23) realize and spool (7) and left valve barrel (1), the sealing of right valve barrel (8), from last, the medium in downstream all can not enter the inner chamber of right valve barrel (8), open blowdown apparatus (27) blowdown this moment earlier, the long-pending stream of inner chamber and the dirt of right valve barrel (8) are drained, and then open in side cover (34) maintenance, outer leaching net, wiper also can be by the endoporus process of mozzle (9) simultaneously.After treating that pigging or blowdown have been overhauled,, continue filter medium by operator (16) rotary valve key 90 degree.If medium is only required coarse filtration, then dismountable Inner filter net (33), filtering agent (31).
Effect of the present utility model is to finish the effect of long-distance transport pipes media filtration and pipeline cleaning blowdown with a filter, do not need to install again by-pass line and line valve system, have and install and use advantage simply and easily: because this filter is when pigging or blowdown, the pipeline medium can not enter the inner chamber of right valve barrel (8), can directly open blowdown apparatus (27) blowdown, pipeline is without stopping transportation, can continuous operation, media filtration and pigging contaminant removal effectiveness have been improved, in the pipeline media filtration, after only needing handover operation device (16) rotational valve core 90 degree, can clear up pipeline; And can directly change filter screen, the transposing filter screen is realized coarse filtration or smart purpose of filtering, and effect of one machine multiple purposes is arranged; Because this filtration device structure is simple, operation also can be used in the pipeline of intermittence filter medium rapidly, and it is low to have a cost, the characteristics that economic benefit is high.
Fig. 1 is the pot strainer structure chart of energy pigging.
Fig. 2 is the cutaway view of AA direction among Fig. 1.
The the installing and using of pot strainer of the utility model energy pigging is directly to be installed on the long-distance transport pipes by end flanges, switch pigging or filter medium with operator (16), dirt can be got rid of from blowdown apparatus (27), opens side cover (34) and just can overhaul, change inside and outside filter screen (30,33) and filtering agent (31).
