Description
Technical field
The present invention relates to sleeve adjusting valve, is related specifically to a kind of anti-residual sleeve adjusting valve of high temperature.
Background technology
Regulating valve plays a very important role in modern plant, is controlled in fluids such as thermal power generation, nuclear power, chemical industry
Had a wide range of applications in occasion.With industrial expansion, regulating valve needs to face increasing special operation condition, among these
Include the heat transfer heat-storage medium of the high heat capacities such as conveying fused salt.Molten fused salt is because its own cost is low, long lifespan and heat exchange property
The advantages that good industrially extensive use, but corresponding, the application of the use of molten fused salt to valve it is also proposed it is new,
Higher requirement.It is most urgently to be resolved hurrily among these, exactly prevent the problem of medium residence is in valve after valve is closed.It is molten
The fusing point of salt is higher, such as the nitrate of molten state, can be remained at 230 DEG C or so at the dead angle of valve.If will not now
It is discharged in time, and the nitrate of molten state will be crystallized and be attached at the dead angle of valve rapidly, causes valve blocks, reaction slow
The problems such as blunt, easily cause the accident.The valve of current anti-residual appears on the market in succession, as involved by CN106051175A
A kind of photo-thermal generating fused salt valve of anti-residual.
The content of the invention
The present invention provides a kind of new anti-residual sleeve adjusting valve of anti-residual, including valve body, bonnet, valve element, valve rod, electricity

New anti-residual sleeve adjusting valve critical piece, valve body, sleeve, core assembly, valve rod, bonnet, filler gasket ring, fill out
Material, gland, pressing plate, support, electric operator are sequentially connected installation positioning from top to bottom, pacify between bonnet and valve body and sleeve
Equipped with pad, valve body is fixed with bonnet using full thread stud and nut.Pass through full thread stud and spiral shell between pressing plate and bonnet
Mother is fixed.Support is fixed with bonnet use to folder nut.
The core assembly is made up of valve element, sealing ring, trim ring, and the valve element is fixed with trim ring using bolt positioning.Institute
It is triangular-section to state sealing ring.The valve element is being machined with skewed slot with trim ring at outlet flow, to ensure that medium will not
Remain in the cavity on core assembly.
Valve body inlet and outlet passage is that low flow resistance is streamlined, and valve seat and valve body are integral type, and the center of its sealing surface
The angle of axis and horizontal plane is 60 °;Groove is machined with close to the position of outlet flow in valve seat, to ensure valve-closed state
Under, be not in medium residual between valve body and core assembly;Linear contact lay is sealed between valve element and valve body, in fluting,
The shape of the contact line of valve body and valve element is not destroyed.
The center circle diameter of the trim ring is bigger 5mm than valve element upper end outside diameter, and the gap is used to connect valve element upper zone
Domain and inlet channel, reduce out-of-balance force suffered on valve element, at the same between also allowing for both it residual liquid outflow.
The valve rod upper end is threaded hole, using to folder nut connection electric operator.The bonnet upper end adds
Work has boss and external screw thread, for fixed support.
The bonnet stage casing is welded with fin, when medium temperature is too high, it is ensured that heat will not reach upper end shadow
Ring the work of executing agency.
The valve element and valve body sealing surface are linear contact lay.The sealing surface cone angle of valve element is 30 °, valve body close front cover and valve element
The angle of axis is 45 °.

Embodiment
Fig. 1 and Fig. 2 be the present invention relates to a kind of new anti-residual sleeve adjusting valve structure principle chart, its mainly by valve body 1,
It is core assembly 2, sleeve 3, packing ring 4, bonnet 5, full thread stud and nut 6, valve rod 7, filler gasket ring 8, filler 9, gland 10, anti-
Konisphere 11, pressing plate 12, full thread stud and nut 13, clamp nut 14, to folder nut 15, support 16, scale-board 17, electronic hold
The part composition of row mechanism 18,18, wherein core assembly 2 is by valve element 21, trim ring 22, balanced seal circle 23, bolt 24, four parts
Composition.
In order to reduce the dead angle quantity of valve cavity, valve seat and valve body 1 are designed as integral type, and in valve body 1 and valve
Pile-up welding hard alloy at the sealing surface that core 21 contacts.Groove a is machined with close to the opening position of outlet flow lead to valve in the sealing surface
At the outlet flow of door.It should be noted that linear contact lay is sealed between valve element 21 and valve body 1, when slotting a, it is impossible to broken
Bad valve body 1 and the shape of the contact line of valve element 21.In order to radiate, fin is welded in the center section of bonnet 5.
Main point of three parts of installation are carried out.Part I, sleeve 3 is directly put into valve body 1.Part II, valve element group
Part 2 by valve element 21, balanced seal circle 23, trim ring 22, fix successively from top to bottom by installation blending bolt 24.Valve rod 7 is screwed into valve element
Component 2, and spot welding is fixed after tightening.After filler gasket ring 8, filler 9 are sequentially placed into the packing cavity of bonnet 5, then by
The valve rod 7 assembled is put in bonnet, is finally sequentially placed into gland 10, dust ring 11, pressing plate 12, is used full thread stud and spiral shell
Mother 13 fixes, and now nut does not need overtorquing.Part III, support 16 and electric operator 18 are fixed.Afterwards, will
Above-mentioned three parts assemble successively.The core assembly 2 of Part II is placed into the sleeve 3 of Part I, bonnet 5 and valve body 1
Contact, after adjustment direction, fixed this two parts using full thread stud and nut 6.It should be noted that core assembly 2
Direction be fixed, it is necessary to which appearance installation as shown in Figure 1, outlet stream is pointed to by the mouth for being used to flow out medium on core assembly 2
Road direction.And then the support 16 of Part III is placed on the boss of bonnet 5, will be solid both it using clamp nut 14
It is fixed, reuse and valve rod 7 is connected by folder nut 15 with executing agency 18, complete installation.
Operation principle is:
When needing valve opening, give electric operator 18 1 opening amount signals, core assembly 2 will be with electronic hold
Center line of the row mechanism 18 along valve rod 7 does upward linear motion, so that valve is in the position of corresponding aperture.When need
Closing valve is, directly to the shutdown signal of electric operator 18, core assembly 2 will be with electric operator 18 along
The center line of valve rod 7 does downward linear motion until core assembly 2 is contacted and shut with the sealing surface of valve body 1.
Need to illustrate is mainly after valve is closed.Compared with the sleeve adjusting valve of routine, valve of the invention is no longer
In the presence of the dead angle that can remain medium.In the lumen of valve, medium directly can flow directly into entering for valve from the passage of core assembly 2
Mouth runner.Medium between core assembly 2 and sleeve 3 will flow into valve along the groove that the window and valve body 1 of sleeve are opened
The outlet flow of door.
Embodiments of the present invention are described in detail above in association with accompanying drawing, but the present invention be not limited to it is described
Embodiment.
