Abstract
The utility model relates to a double valve seat adjustable valve, which comprises a bottom cap, a valve plug, a valve body, a valve cap, sealing packing, a packing gasket, a packing gland, an upper guide sleeve, a valve rod, a locating pin, an upper valve seat, a lower valve seat and a connecting piece. The valve body is a large valve cavity structural valve body with an upper valve seat dividing wall and a lower valve seat dividing wall. The valve plug is a double valve plug structure adopting an integral identical discharge characteristic curve, and a double guiding structure with two positions to guide, namely the upper guide sleeve and a stifle at the bottom of the valve body. A balance hole is respectively fabricated on the stifle and the upper guide sleeve, and a copper bush made of tin bronze is used for inlay between the upper guide sleeve and a guide hole on the stifle. The double valve seat adjustable valve has the advantages of being small in pressure reduction loss, large in flow, wide in adjustable scope, good in movement stability, particularly suitable for a pipe system under working under conditions where nominal diameter (DN) is larger than 200, larger in valve front and back differential pressure, large in required rated flow and not high in leakage grade requirements, and a medium of the pipe system contains fine impurities.
Description
Technical field
The utility model relates to a kind of adjusting control valve, particularly relates to a kind of bivalve seat modulating valve.
Background technique
Single-seat adjusting valve, sleeve adjusting valve are in the current various industrial fluids control system, most widely used two kinds of modulating valve.Though single-seat adjusting valve has advantages such as droop loss is little, leakage rate is little, because of employing top guide structure, and bear unbalanced force, be applicable to that not too valve front and back pressure reduction is big or contain the use of minute impurities medium operating mode.Though and sleeve adjusting valve has advantages such as allowing pressure reduction is big, good stability, when valve aperture was big, the sleeve spool valve structure size was corresponding just very big, was easier to produce distortion, be fabricated onto higher quality of fit, and difficulty of processing is just bigger.
Summary of the invention
The purpose of the utility model is: the bivalve seat modulating valve that provides a kind of and be applicable to that pressure reduction before and after the valve is big, requires rated flow coefficient is big, leakage class is less demanding, medium contains fine particle impurity operating mode pipe-line system to use.
The technical solution of the utility model is: a kind of bivalve seat modulating valve comprises bottom 1, spool 2, valve body 3, valve gap 4, stuffing box packing 5, filler packing ring 6, Gland 7, goes up guide sleeve 8, valve rod 9, locating stud 10, upper valve base 11, lower valve base 12 and coupling.Said valve body is a kind of big valve pocket structure valve body of two valve seat partitioning walls up and down that has, and makes the rated capacity of its valve pocket want big more than 10% than single seat, sleeve adjusting valve.
Said spool adopts the dual-guiding structure of going up guide sleeve, stifle two places, valve body bottom guiding, has improved spool anti-unbalance power impact capacity and working stability.According to the working condition needs, but said spool, valve seat built-up welding stellite,, scour resistance corrosion-resistant to improve.
Said spool adopts the double spool structure of integral type with rating curve, makes that two circulation passages are realized identical Flow-rate adjustment characteristic up and down, and the sealing effect that two circulation passages are closed simultaneously about reaching.Said spool, the closed surface of contact of valve seat adopt taper contact seal.Said spool can adopt the soft sealing structure that is assembled with the stainless steel material part by the reinforced TFE sealing plate.
Said valve rod lower end screws in spool upper end screw, and gets loose with fastening the preventing of locating stud.The valve rod upper end is passed valve gap and can be moved up and down, and is added with stuffing box packing between valve rod and the valve gap, compresses through filler packing ring, Gland, realizes that sealing prevents to leak outside.The valve rod upper end can connect the pneumatic or electric actuator of different model.
Said stifle has the pilot hole that supplies spool lower end guiding, and the said pilot hole of going up on guide sleeve and the stifle is inlayed the copper sheathing that adopts tin bronze processing, plays anti-interlock and improves the wear resistance effect.
On said stifle and last guide sleeve, be processed with equalizing orifice, be used for medium in the valve pocket is introduced in the separate cavities that forms between valve body and valve gap, spool and the stifle, to reduce the suffered unbalanced force of spool.
The beneficial effect that the utility model brings is: droop loss is little, flow is big, adjustable extent is wide, action stability is good, be specially adapted to bore big greater than pressure reduction before and after the DN200, valve, require the pipe-line system that rated flow is big, leakage class is less demanding, medium contains the fine impurities operating mode to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the another kind of soft seal spool of the utility model embodiment's a structural representation.
Embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model.
Among the embodiment like Fig. 1, a kind of bivalve seat modulating valve comprises bottom 1, spool 2, valve body 3, valve gap 4, stuffing box packing 5, filler packing ring 6, Gland 7, goes up guide sleeve 8, valve rod 9, locating stud 10, upper valve base 11, lower valve base 12 and coupling.
Said valve body is a kind of big valve pocket structure valve body of two valve seat partitioning walls up and down that has, and two valve seats are individually fixed on the partitioning wall up and down of body cavity, are fixed with gasket seal between valve seat and the valve body.
Said spool employing is installed on the last guide sleeve on valve body top and the guide structure of the guiding of stifle two places bottom the valve body respectively, has improved spool anti-unbalance power impact capacity and working stability.According to the working condition needs, but spool, valve seat built-up welding stellite,, scour resistance corrosion-resistant to improve.
Said spool adopts integral type double spool structure, and two spools are processed with identical rating curve, makes that two circulation passages are realized identical Flow-rate adjustment characteristic up and down, and the sealing effect that two circulation passages are closed simultaneously about reaching.Said spool, the closed surface of contact of valve seat are taper contact seal.
Said valve rod lower end screws in spool upper end screw, and gets loose with fastening the preventing of locating stud.The valve rod upper end is passed valve gap and can be moved up and down, and is added with stuffing box packing between valve rod and the valve gap, compresses through filler packing ring, Gland, realizes that sealing prevents to leak outside.The valve rod upper end can connect the pneumatic or electric actuator of different model.
