Deposition, the anti-clogging leakproof fused salt Corniform regulating valve of blocking can be difficult to, to overcome prior art to exist by solidification and crystallization medium excellent, easy
Not enough.Technical solution of the present utility model is: anti-clogging leakproof fused salt Corniform regulating valve, including valve body, spool, valve rod, close
Gasket, bellows component, airtight and watertight padding, gland, insulation jacket and securing member, described valve gap is fixed on valve body upper end,
Valve gap inner chamber arranges bellows component, upper end solid welding appropriate location in the middle part of valve rod of bellows component, bellows component
Lower seal sleeve-board is located between valve body and valve gap, and its upper and lower surface respectively adds a gasket seal and seals；Spool is fixed on valve rod
Lower end, valve rod upper end couples with executor after valve gap stuffing-box passes, it is characterised in that: described valve body is integral type angle valve
Body, it imports and exports runner is Venturi tube planform, and valve outlet runner top directly processes and the sealing of spool adaptation
Sealing cone, described gasket seal is 316L profile of tooth sealing gasket, and described valve body, the outside of valve gap all add insulation jacket.
As preferably, the horizontal run of described dihedral valve body is inlet channel, and runner straight down is outlet flow, more
Be conducive to the happy circulation of fused-salt medium.
As preferably, described valve body, valve gap use CF8M material steel-casting, and described spool, valve rod are equal with bellows component
Use 316L material to manufacture, be effective against the corrosion of fused-salt medium.
As preferably, between the insulation jacket added outside described valve body, valve gap, use cross over pipe UNICOM, and setting adds heating agent
Jie's entrance point and each one of the port of export, form circulation for steam or other thermal mediums at insulation jacket intracavity, promote valve
The uniform heating and thermal insulation of intracavity fused-salt medium.
As preferably, described valve core sealed cover and the valve outlet equal pile-up welding hard alloy of runner sealing cone, to carry
Its case hardness high, thus effectively strengthen its antiscour, abrasion resistance properties.
As preferably, described spool is shaped with percentage ratio rating curve, to realize the precise equalization regulation control of convection cell
System.
This utility model can have the benefit that
1, using integral type dihedral valve body, valve pocket stream is the most smooth and easy, and it imports and exports runner is Venturi tube planform,
Fluid can be made to produce swabbing action when flowing through restriction, and fluid is fast by restriction flow velocity, and fused-salt medium can be prevented at valve pocket
Interior generation deposition, blocking, self-cleaning property is good.After fluid flows through restriction simultaneously, flow velocity and pressure are the most quickly reduced, and can have
Effect alleviates high pressure, the high-velocity fluid erosion attack to spool Yu runner inner wall, prolongation valve service life.
2, valve outlet runner top directly processes the sealing cone sealed with spool adaptation, and inner chamber, without dead angle, can be kept away
Exempt to use traditional valve that valve seat is installed at valve body restriction position, because at cooperation, to there is transition unavoidably the most smooth and easy or deposit on surface
In gap, fused-salt medium is easily caused to produce deposition or blocking at this position.
3, valve stem seal uses corrugated tube and soft graphite dual-seal, can be effectively improved the tightness of valve stem seal with close
Envelope persistency.
4, valve body valve cover chamber use 316L profile of tooth sealing gasket seal, can prevent normal flexible graphite pads or metal wound gasket because of
The deep-etching of high-temperature molten salt and cause seal failure.
5, valve body all adds insulation jacket with the outside of valve gap, utilizes steam or other thermal mediums easily to coagulate in valve pocket
Gu, crystallization fused-salt medium carry out heating and thermal insulation, prevent it from solidification or crystallization occurring in valve pocket, the normal production of impact.
