Abstract
The utility model relates to a noise reduction type adjusting valve. A valve seat loop sealing ring is arranged on a valve body, a valve seat loop is arranged on the valve seat loop sealing ring, a valve cage is arranged on the valve seat loop, an elastic sealing ring is arranged on the valve cage, a valve cover sealing ring is arranged on the elastic sealing ring and the valve body, a valve cover is arranged on the valve cover sealing ring, a padding assembly is arranged in a center hole of the valve cover, the lower end of a valve rod is fixed on a valve core, a supporting ring and a sealing loop are sheathed in a groove of the valve core, the upper end of the valve rod penetrates out of the top part of the valve cover from the padding assembly, and the valve body and the valve cover are fixed by a screw. A plurality of through holes which are regularly arrayed or a plurality of narrow through grooves which are arrayed in parallel are arranged on the circumferential surface of the valve cage. The noise reduction type adjusting valve has the characteristics of obvious noise reduction effect, good sealing property and high leakage grade.
Description
Technical field
The utility model relates to a kind of modulating valve, particularly a kind of noise reduction sound formula modulating valve.
Background technique
At present, in a lot of industrial departments such as chemical industry, oil, power station, generally the modulating valve product of Shi Yonging can produce huge noise when circulation medium is swiftly flowing gas or steam, and is very big to surrounding environment influence.For this class noise operating mode occasion bigger than normal, common modulating valve can't solve.
Summary of the invention
Problem in view of above existence, the utility model provides a kind of noise reduction sound formula modulating valve, concrete technological scheme is: a kind of noise reduction sound formula modulating valve, comprise: valve body, the seat ring seal ring, valve rod, valve gap, filler assembly, it is characterized in that: also comprise seat ring, spool, bracing ring, seal ring, valve cage, elastic seal ring, the valve bonnet seal circle, described seat ring seal ring places on the valve body, seat ring places on the seat ring seal ring, valve cage places on the seat ring, elastic seal ring places on the valve cage, the valve bonnet seal circle places on elastic seal ring and the valve body, valve gap places on the valve bonnet seal circle, and filler assembly places in the bonnet central bore, and the valve rod lower end is fixed on the spool, bracing ring and seal ring set valve rod upper end in the spool groove passes the valve gap top through filler assembly, and valve body and valve gap are screwed.The narrow groove that the valve cage circumferential surface has several regularly arranged through holes or is arranged in parallel.
The beneficial effects of the utility model are: have tangible noise reduction audio fruit, and also good airproof performance, the leakage class height.
Description of drawings
Fig. 1 is the utility model structural representation and as Figure of abstract.
Fig. 2 is an A part enlarged view of the present utility model.
Fig. 3 is a B part enlarged view of the present utility model.
Fig. 4 is a valve cage structural representation of the present utility model.
Among the figure 1, valve body, 2, the seat ring seal ring, 3, seat ring, 4, spool, 5, bracing ring, 6, seal ring, 7, valve cage, 8, elastic seal ring, 9, the valve bonnet seal circle, 10, valve rod, 11 valve gaps, 12, filler assembly.
Embodiment
Shown in Fig. 1,2,3,4, bore several regularly arranged garden through holes in the bottom of valve cage 7 circumferential surfaces.Seat ring seal ring 2 is placed on the valve body 1, seat ring 3 places on the seat ring seal ring 2, valve cage 7 places on the seat ring 3, elastic seal ring 8 places on the valve cage 7, valve bonnet seal circle 9 places on elastic seal ring 8 and the valve body 1, valve gap 11 places on the valve bonnet seal circle 9, filler assembly 12 places in valve gap 11 center holes, valve rod 10 lower ends use dowel fixes on spool 4, bracing ring 5 and seal ring 6 are enclosed within spool 4 grooves valve rod 10 upper ends and pass valve gap 11 tops through filler assembly 12, and valve body 1 and valve gap 11 are screwed.
The modulating valve of this structure be adopt have the valve cage part of some and the regularly arranged through hole of certain size or have some and the valve cage part of certain size parallel narrow groove as main noise reduction device.This structure can effectively reduce fluid turbulence on the basis that does not influence the valve negotiability, greatly reduce the mechanical energy of fluid, has reduced the pressure reduction of fluid, has tangible noise reduction audio fruit.
The modulating valve of this structure is to have adopted hard sealing and elastic packing structure combining mode to improve the earial drainage grade, so-called hard sealing is meant that spool 4 cooperates with metallic seal between the seat ring 3, valve cage 7, seat ring 3 all float and are placed on above the valve body 1, make spool 4 directly and seat ring 3 match, replaced the former valve cage 7 and the structure of seat ring 3 integral types.So-called elastic packing is meant bracing ring 5 and the seal ring of installing 6 on spool 4, make seal ring 6 directly and valve cage 7 match, the structure that metallic seal cooperates between valve cage 7 before having replaced and the spool 4, adopt after this structure, as long as assembling is correct, spool 4 can automatic centering, and sealing improves greatly, and leakage class gets a promotion.
Claims (2)
