Abstract
A kind of pot strainer that can pigging is by valve body, spool, go up lower valve shaft, honeycomb duct, key, bottom, side cover, sliding bearing, axle sleeve, pad, pressure ring, O type circle, operator, valve seat supporting, seat ring, spring, interior outer leaching net, filtering agent and drainage device constitutes, this filter can be directly installed on and carry out media filtration on the main line; During pigging, as long as the handover operation device with valve core rotation 90 degree, gets final product pigging, and can blowdown.Have easy for operationly, the advantage of pipeline media filtration continuous operation, and maintenance are changed filter screen easily and the characteristics of a tractor serves several purposes.
Description
The present invention relates to universal machine valve technology, belong to the improvement of pot strainer structure, be applicable to long-distance transport pipes or need and play a kind of filter medium on the general industry pipe line of pigging.
Existing long-distance transport pipes particularly carry height to contain the pipeline of wax crude oil and non-purified natural gas medium, and general industry pipeline, growth along with service time, all require pigging, but the at present both at home and abroad existing 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 pipe-line-network of bypath system, open and be positioned at filter, forward and backward stop valve; When needs cleanings pipeline or when changing filter screen, 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 invention is to provide a kind of online filter of energy pigging, only need make the handover operation device, rotational valve core 90 degree, the purpose that just can finish the pipeline media filtration and clear up pipeline reaches and operates rapidly effect easy to install.
The pot strainer of the present invention's energy pigging is made of left and right valve body, spool, last lower valve shaft, honeycomb duct, key, bottom, side cover, sliding bearing, axle sleeve, pad, pressure ring, O type rubber ring, nut screw, bolt, operator, valve seat supporting, seat ring, spring, inside and outside filter screen, filtering agent and drainage device.
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 (8).Seal by O type circle (6); The same honeycomb duct 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); Drainage device (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 present invention 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 product can be bought to market.Sliding bearing (22,29) applies teflon 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 working machine tool.
When from the medium of upstream side by the gap between spool (7) and honeycomb duct (9) after, through Inner filter net (33), after the filtration of filtering agent (31) and outer leaching net (30), flow to the downstream side, 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), honeycomb duct (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 long-pending stream of inner chamber and dirt drainage that drainage device (27) blowdown makes right valve barrel (8) this moment earlier, and then open in side cover (34) maintenance, outer leaching net, wiper also can be by the endoporus process of honeycomb duct (9) simultaneously, after treating that pigging or blowdown have been overhauled, by operator (16) rotary valve key 90 degree, continue filter medium.If medium is only required coarse filtration, then dismountable Inner filter net (33), filtering agent (31).
Effect of the present invention is to finish the effect of long-distance transport pipes media filtration and pipeline cleaning blowdown with a filter, does not need to install by-pass line and line valve system again, has and installs and uses 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 drainage device (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, only behind need handover operation device (16) rotational valve core 90 degree, can clear up pipeline; And can directly change filter screen, or realization coarse filtration of transposing filter screen or smart purpose of filtering, effect of one machine multiple purposes is arranged, because this filtration device structure is simple, operation rapidly, also can be used in the pipeline of intermittence filter medium, it is low to have a cost, the characteristics that economic benefit is high.
Fig. 1 is the pot strainer structural drawing of energy pigging.
Fig. 2 is the sectional view of AA direction among Fig. 1.
The the installing and using of pot strainer of the present invention's energy pigging is directly to be installed on the long-distance transport pipes by end flange, switch pigging or filter medium with operator (16), dirt can be got rid of from drainage device (27), opens side cover (34) and just can overhaul, change inside and outside filter screen (30,33) and filtering agent (31).
