Abstract
The utility model focuses on solution lower valve rod salification, bottom blind flange leakage salt and wafer type flange gasket installation question, discloses a kind of double eccentricity compensation formula hemisphere fused salt valve, the structure such as including valve body, spool, upper valve rod, valve seat, hold-down grid, sealing ring.Sealing between spool and valve body uses double eccentric wedging principle；Sealing ring between seal spool ball and valve body, valve seat, uses high-tech nano ceramic material.The utility model has an obvious using effect: not only valve dismounting, install more convenient, and the problem being difficult to flange leakage salt and lower valve rod salification occur.
Description
Technical field
The utility model relates to ball valve field, is specifically related to a kind of double eccentricity compensation formula hemisphere fused salt valve.
Background technology
In aluminum oxide production process, contain solid particle for control and easily separate out the slurry valve of crystallization, its sealing property and service life how being ensured of problem present in reality.
What aluminum oxide industry valve was conventional is plug valve, gate valve, stop valve etc..Plug valve (cock) uses conical surface wedging to seal, and rotation torque strengthens, and switchs more difficult, even twist off spool during fouling；Gate valve uses the axial wedging of flashboard to seal, and can accelerate abrasion and leak during fouling, and particularly bottom " dead band " is piled up fouling and caused Guan Bushang, additionally, pair is sealed in switching process abrasion, fragile；Ball valve includes fixing spherical ball valve, semisphere valve etc., and feature is that the pretightning force by valve seat seals, and pretightning force causes sealing surface frictional force to increase, and driving torque strengthens, because leaking without automatic compensation after sealing surface wear；Stop valve includes Y-shaped cut-off valve (KLEIN company of France slurry valve), tapered stop valve etc., and common feature is that curve crosses stream, and resistance is big, and fouling is serious, and front compresses and seals and fit badly.Valve fouling in use and the subject matter that abrasion is aluminum oxide industry valve, life of valve is short, directly influences the properly functioning of production.
The electronic dissolved salt valve generally using is that V-structure globe valve, valve body are electrical heating wire without automatic heating device, valve body outer wrapping, easily produce that leak, heat time be slow and power consumption.The application of Double-eccentric hemisphere valve solves the problem affecting solution conveying because of crystallization precipitation, fouling etc. in production procedure.But in use, still there is flap abrasion in Double-eccentric hemisphere valve, lower valve rod salification, bottom blind flange leakage salt, wafer type flange install the problems such as pad more bothers, valve spare part and the electric transmission machanism running part size of former use are not mated.
Utility model content
For problem above, the utility model provides one not leakiness salt, removes and installs convenient novel molten salt valve.
The technical scheme that the utility model provides:
A kind of double eccentricity compensation formula hemisphere fused salt valve, including valve body, spool, upper valve rod, valve seat, hold-down grid, sealing ring；Sealing between spool and valve body uses double eccentric wedging principle；Valve seat is arranged on valve body by disc holder, and is provided with sealing ring between valve body；The lower end of spool is connected with lower valve rod, is provided with sliding shaft between the two, lower is provided with sealing ring between axostylus axostyle and valve body；Valve gap has screw to be arranged on valve body, and is provided with sealing ring between valve body；Being provided with sliding shaft, Packing seat, filler between upper valve rod and valve body, filler upper end is press-fited by gland；Support is bolted on installation valve body；It is characterized in that, described sealing ring material is nano ceramics.
Preferably, described a kind of double eccentricity compensation formula hemisphere fused salt valve also includes actuator, can match worm gear type, air-driven type or power type transmission.
Preferably, described a kind of double eccentricity compensation formula hemisphere fused salt valve also includes fin.
Preferably, described a kind of double eccentricity compensation formula hemisphere fused salt valve also includes electrical heating case.
Preferably, the filler in described hold-down grid is soft graphite or leaching teflon asbestos filler.The two all can keep good flexibility, and rotating friction force is little under high/low temperature operating mode, it is ensured that pressure medium drop does not leaks.
Preferably, described rotating shaft is high pressure resistant oilless bushing.It is being not required to add under lubricating oil state, it is ensured that the rotating shaft energy flexible rotating of crunch, and axle sleeve abrasion is minimum.
Spool uses double eccentric wedging principle, makees 90 degree and opens and closes rotary motion, and sealing ring can be made to be rapidly separated when opening and closing and rotating and fit, and the friction between sealing ring is almost " zero ", therefore greatly increases the service life of this valve.In the case that Long-term fluid medium washes away friction, automatic forced can compensate, can ensure that and fit between sealing ring, sealing property is reliable.Can be hidden in during unlatching at the non-stream excessively of valve in-vivo medium, area of passage is big, and non-resistance, the rate-of flow pressure loss is zero.
Spool and the sealing ring of valve body, valve seat composition, use high-tech nano ceramic material.The only viscous stone of hardness and super abrasive degree can open and close and also do not wear and tear for 10,000 times in contrast.Can resist and suppress medium and wash away, the life-span is long.Seal spool ball and valve seat open and close wrong mask the tough and tensile edge of a knife, makes sealing ring have superior rejection when opening and closing rotary motion.Easy to do can cut off and clean except the isomery on attachment sub-sealing-ring face, sediment, foulant etc., therefore open and close unobstructed, without stuck phenomenon.
Spool can be made 90 degree by rotating shaft and open and close rotary motion by actuator.Actuator can match worm gear type, air-driven type, power type transmission according to operating mode needs.Pneumatic, power type opens and closes, at valve, the electronic open and close device that operating element have employed two bit motion formulas, enhance system reliability of operation, particularly poisonous, harmful, inflammable, explosive at those, under adverse circumstances, more demonstrate that superiority, electric operating element and instrument adjustment unit can realize Automated condtrol, regulation and functionalized control.This valve is made individually to control, it is possible to realize that Central Control Room is concentrated or number machine control.
The beneficial effects of the utility model
This valve focuses on solution lower valve rod salification, bottom blind flange leakage salt and wafer type flange gasket installation question, the using effect of the compensation globe valve of nano ceramic material sealing ring improveing and producing after investigating is more obvious: valve dismounting when the 1st, overhauling, install more convenient, and is difficult to flange leakage salt condition occur；2nd, effectively solving valve lower valve rod salification cannot the problem of controlled valve.
