Description
Technical field
The utility model relates to valve field, specifically a kind of split type band filter screen ball valve.
Background technique
Ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.Be provided with spheroid in ball valve, realize opening or closing the function of medium channel mainly through spinning ball, then cut-outs can be played, distribute and the effect in change media flow direction.
In the prior art, when the medium containing impurity enters ball valve sealing face, can accelerate the rate of wear in ball valve sealing face, the ball valve after wearing and tearing needs spheroid and valve seat to take out and carries out fine finishing reparation again and again reach requirement to sealing, and serious wear can only use new spheroid and valve seat.So not only complicated operation, and financial cost is high.
Model utility content
The utility model provides a kind of split type band filter screen ball valve, is intended to reduce ball valve and reprocesses frequency and difficulty, save financial cost.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of split type band filter screen ball valve, comprise valve rod, spheroid, valve seat, it is characterized in that: valve body is divided into one-level valve body and secondary valve body, spheroid is arranged in one-level valve body; Described valve seat is fixed in seat ring, and spheroid of fitting forms sealing surface; Described seat ring is arranged in one-level valve body, and one end of seat ring exceeds one-level valve body, and is provided with radial boss, and boss is axially provided with through hole; Described one-level valve body and secondary valve body all have the bolt hole with through hole adaptation on boss, and one-level valve body, secondary valve body and seat ring are bolted; Be provided with two-layer filter screen in described secondary valve body, between two-layer filter screen, have sewage-storage trough; Have pollutant exhaust hole bottom described sewage-storage trough, and be provided with the plug with pollutant exhaust hole adaptation.
Further, be also provided with elastic compensating structure in described seat ring, comprise disc spring and pad, disc spring one end is against seat ring, and pad is arranged between disc spring and valve seat.
Further, the surface of contact of described valve seat and seat ring is provided with and seals O shape and enclose.
Further, described secondary valve body and boss surface of contact axially have the groove placing seal ring.
Further, described seal ring is the sealing plain cushion of teflon material.
Further, described two-layer filter screen, at close seat ring one deck is fine and closely woven filter screen, and the one deck away from seat ring is broad filter screen.
Further, described plug has the annular groove placing seal ring.
The beneficial effects of the utility model are:
One, first, valve body is divided into one-level valve body and secondary valve body, achieves the detachability of valve body, split type valve body is also more easily produced.
Two, secondly, be provided with two-layer filter screen in secondary valve body, if filter screen damages, or after residue excessively blocks, secondary valve body can be dismantled and carry out changing and cleaning, convenient and simple.
Three, again, it is fine and closely woven filter screen that filter screen puts in one-level valve body inner port near secondary valve body, putting in one-level valve body inner port away from secondary valve body is broad filter screen, double-deck different filter screen can make contamination precipitation in sewage-storage trough, timing is got rid of from pollutant exhaust hole, realize filtering function, greatly reduce the content of impurity, the rate of wear in ball valve sealing face is reduced.
Four, last, one-level valve body and secondary valve body, the coordinating of seat ring, make when reprocessing, the dismounting of ball valve becomes easier, valve seat can not because of the damage sealing surface that collides with in the unloading process of complexity, valve seat only need be ground again and reach seal request, reduce the probability more renewing valve seat, save financial cost.
Accompanying drawing explanation
Fig. 1 is the split type band filter screen ball-valve structure schematic diagram that the utility model provides.
Mark in figure: 1 be secondary valve body, 2 be broad filter screen, 3 be fine and closely woven filter screen, 4 be sewage-storage trough, 5 be plug, 6 be annular groove, 7 be seat ring, 8 be one-level valve body, 9 be spheroid, 10 be plain cushion, 11 be disc spring, 12 be valve seat, 13 be valve rod, 14 be sealing O shape circle, 15 be sealing plain cushion.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1, a kind of split type band filter screen ball valve, comprises valve rod 13, spheroid 9, valve seat 12, and valve body is divided into one-level valve body 8 and secondary valve body 1, and spheroid 9 is arranged in one-level valve body 8; Described valve seat 12 is fixed in seat ring 7, and spheroid 9 of fitting forms sealing surface, and valve seat 12 and the surface of contact of seat ring 7 are provided with and seal O shape and enclose 14.Also be provided with elastic compensating structure in seat ring 7, comprise disc spring 11 and pad 10, disc spring 11 one end is against seat ring 7, and pad 10 is arranged between disc spring and 11 valve seats 12.Described seat ring 7 is arranged in one-level valve body 8, and one end of seat ring 7 exceeds one-level valve body 8, and is provided with radial boss, and boss is axially provided with through hole; Described one-level valve body 8 and secondary valve body 1 all have the bolt hole with through hole adaptation on boss, and one-level valve body 8, secondary valve body 1 are bolted with seat ring 7.Be provided with two-layer filter screen in described secondary valve body 1, between two-layer filter screen, have sewage-storage trough 4; Described secondary valve body 1 axially has with boss surface of contact the groove placing seal ring, and seal ring is the sealing plain cushion 15 of teflon material.At the bottom of described sewage-storage trough, 4 have pollutant exhaust hole, and are provided with the plug 5 with pollutant exhaust hole adaptation, plug 5 have the annular groove 6 placing seal ring.Described two-layer filter screen, at close seat ring one deck is fine and closely woven filter screen 3, and the one deck away from seat ring is broad filter screen 2.
In use, medium impurity is first through broad filter screen 2, and less impurity passes through, and larger foreign matter is stopped, precipitation enters sewage-storage trough 4.After broad filter screen 2, MEDIA FLOW is filtered again through fine and closely woven filter screen 3, and impurity is entered sewage-storage trough 4 by stop and precipitates.Often after a while, open plug 5, emit the impurity and foreign matter that continue in sewage-storage trough 4 from pollutant exhaust hole.After twice filtration, the impurity entered between spheroid 9 and valve seat 12 greatly reduces, and the rate of wear between spheroid 9 and valve seat 12 slows down, and reprocesses frequency and slows down.But impurity can not be exempted completely, after long-term use, wear and tear unavoidably between spheroid 9 and valve seat 12, when reprocessing, only need take out secondary valve body 1 can disassemble seat ring 7, takes out valve seat 12, valve seat 12 can not because of the damage sealing surface that collides with in the unloading process of complexity, valve seat 12 only need be ground again and reach seal request, reduce the probability more renewing valve seat, save financial cost.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
