Embodiment
See accompanying drawing, a kind of heavy-caliber high-temperature high pressure sleeve adjusting valve in present embodiment, comprise valve body 101, bonnet 105, spool 103, valve seat 102, sleeve 104, valve rod 106, described valve body 101 has tunnel inlets and runner exit, valve body 101 lumen arranges described valve seat 102, sleeve 104 is arranged in valve body epicoele, sleeve 104 and valve seat 102 be coaxial to be arranged and sleeve 104 is connected to above valve seat 102, described sleeve 104 offers flow window, spool 103 drives axial activity in sleeve 104 and spool and sleeve Spielpassung by valve rod 106, poppet shaft is to the size of the orifice size of activity adjustment spool and sleeve flow window, described flow window comprises the perforate window being arranged on sleeve hypomere and the subtriangular window be arranged on above perforate, the linear characteristic of described Perforated window interruption-forming valve small guide vane flow, described subtriangular window forms the equal percentage characteristics of the large aperture flow of valve.As preferably, adopt the sealing means of linear sealing between described spool 103 and valve seat 102, assemble without the need to grinding, and potted line is positioned at valve seat inboard, not easily scratching occurs, and is that modulating valve opens and closes by spool with coordinating of valve seat.Carried out the size of the orifice size of regulating spool and sleeve flow window by the axial activity of spool 103, the change of the orifice size by spool and sleeve window changes by medium parameter, thus reaches the object such as pressure, flow, temperature of control media.The epicoele of described valve body 101 is provided with the guide plate 203 for avoiding eddy current to produce, and this guide plate is positioned at the outside of sleeve, avoids medium to produce eddy current at valve body epicoele due to large pressure reduction, produces eddy current and cause Spool rotating phenomenon after can avoiding medium throttling.Described valve seat about 102 is symmetrical arranged, and turningly after valve seat erosive wear reuses.Valve body has epicoele, lumen and cavity of resorption, and valve body by optimal design, makes valve body cavity of resorption runner smooth, without circulation dead band, effectively avoids that medium in heavy caliber high pressure difference situation produces eddy current and the large situation of noise occurs.
Tapering is adopted to be located by connecting between spool 103 and valve rod 106, make that there is between spool with valve rod the conical surface to coordinate, valve rod can be avoided to rock, ensure travel displacement straightness accuracy, ensure adjusting function, extend filler working life simultaneously, and avoid swipe phenomenon occurs, adopting tapering to be located by connecting between spool and valve rod to compensate gap, then cannot in Spielpassung location.
Valve rod also can arranging spanner, off-position can being set complete machine adjustment, without the need to pulling down the link with drive unit.See Fig. 6, if valve rod and output shaft are integrally connected up and down, need to guarantee that valve rod and output shaft coaxality are consistent, namely axis will overlap, in the process of assembling, usually make their keep always by force, makes valve rod or output shaft occur the phenomenons such as bending; Part Fig. 5, as preferably, valve rod described in present embodiment is connected by connecting base two-piece unit with the output shaft of drive unit, is fixed by attaching nut, screw rod, can make up valve rod and output shaft coaxiality deviation, not affect driven.
Sleeve and spool carry out analytical calculation by material expansion coefficient, ensure to keep rational Spielpassung under worst hot case, and control performance is guaranteed, and fault phenomenon can not occur.Avoid fault existing---after avoiding temperature to raise, the thermal expansion phenomenon of material, matching gap diminishes, and " locking " phenomenon occurs.Pad 201,202 controls to compress in elastic range, avoids losing efficacy.
The heat radiating type bonnet that bonnet 105 adopts integrally casting shaping, adopts the bonnet of heat radiating type can efficiently radiates heat, and under ensureing high-temperature condition, bonnet heat radiation highly reaches safety temperature, avoids electric attachments to be subject to high temperature failure.Meanwhile, stuffing box temperature reaches filler Applicable temperature scope, ensures Reliability of Packing Seal; But common way is radiating fin is the welding manner of steel plate, this time design adopts integral casting forming, and integrally casting is shaping, and thermal resistance is low, and radiating effect is better.After being dispelled the heat by bonnet, effectively can lower temperature, thus ensure that the sealing of filler and other parts, annex use at safe temperature range.
Be that filler 302(the present embodiment adopts flat filler between described bonnet 105 and valve rod 106), bonnet is provided with filler cavity, filler cavity bottom has Packing seat 301, this filler cavity opening up and unlimited, filler 302 and filler cover 303 are positioned at filler cavity, filler cavities open place arranges Gland 304, packing spring 305 is placed on the top of Gland, the top of packing spring arranges pressing plate 306, and described pressing plate 306 fixing (adopting bolt 604, nut 603) is above bonnet filler cavities open.Spring, by external originally external at modulating valve, can be avoided being subject to dielectric corrosion, increase the service life, avoid changing stuffing box online and impact production process.
