High-temperature material from inlet transforms pipe 1 enter, 10 side of spool be provided with runner hole and with 141 entrance of valve body connecting tube Match, Fig. 2 show on-state (unlatching), and material can flow into inside spool 10 at this time, and flows out from discharge connection 12.Fig. 3 institute It is shown as closed state, i.e. spool 10 rotates 180 ° relative to valve body 14, and runner hole 1011 is opposite with 14 entrance of valve body at this time.Spool 10 Rotation by 4 driving devices (rack-and-pinion oscillating cylinder) realize.

The performance quality key of high temperature solid-state material plug valve is leakproofness.There are two requirements for sealing, first is that inside valve Channel and external sealing, that is, prevent from leaking outside；Second is that when the valve 4 is in a closed state, the sealing of upstream passageway and downstream passage, Prevent interior leakage.By graphite annulus gland 5, Rectangular Spring 6, gasket ring 7, graphite annulus I8, graphite annulus II9, wind-lace 11 and valve Core 10 constitutes a set of sealing unit in itself.

The seal assembly for preventing leakage from being mainly made of graphite annulus I8 and graphite annulus II9 compresses reality by graphite annulus gland 5 Existing, graphite annulus I8 and graphite annulus II9 are wedge structure.Under 5 pressuring action of graphite annulus gland, graphite annulus I8 and graphite annulus II9 Distending simultaneously is close to generate contact force with 10 outer wall of spool, 14 outer wall of valve body respectively, to realize sealing.It is preferable close in order to reach Effect is sealed, the graphite annulus I8 and graphite annulus II9 of wedge structure should use multiple groups, this example uses four groups.Rectangular Spring 6 and pad The effect of ring 7 is that graphite ring assemblies is made to be in impaction state always, and initially Rectangular Spring 6 is in compressive state when installation, repeatedly Graphite annulus may generate abrasion when opening and closing operation, and automatic compensation, graphite annulus pressure can be achieved under the action of Rectangular Spring 6 at this time Lid 5 also has certain adjusting stroke, and after long-play when Rectangular Spring 6 excessively relaxes, stone can be made by being tightened by bolt Black ring gland 5 compresses Rectangular Spring 6 again.Graphite annulus I8 and graphite annulus II9, by suppressing, is resistant to by flexible graphite material 500 DEG C of temperature.

Prevent interior leakage from being mainly made of spool 10 and the wind-lace 11 inlayed thereon.Wind-lace 11 is by tin bronze material Material is made, circumferentially a plurality of along spool 10 and be through to two sides shoulder, this exemplary arrangement five (according to 10 valve core diameters Size can suitably accelerate).The enveloping surface and 14 inner cylinder face of valve body that more wind-laces 11 are constituted relatively are fitted close, this Fit clearance should be less than the fit clearance of spool 10 ontology external cylindrical surface and 14 inner cylinder face of valve body, and the purpose is to reduce mating surface Contact area prevents from thermally expanding under high temperature action by 10 locking of spool.More wind-laces 11 and 14 inner cylinder face of valve body are close Cooperation, and issuable internal leakage channel has been blocked jointly with the graphite annulus end face at 10 shoulder of spool.

Spool 10 is hollow structure, and material enters valve core inside from valve port, is then flowed out from the discharge connection of docking 12, and 10 inside latus rectum of spool is consistent with 12 latus rectum of discharge connection, utmostly reduces flow resistance, prevents material accumulation；On the other hand 10 hollow structure of spool can also reduce spool weight.Inlet transforms pipe 1 be used for in-site installation when and upstream line orientation adjustment, It can be set to different angles, this example only illustrates a kind of orientation.Field is used into, discharging for only relying on material gravity It closes, answers vertically-mounted；If upstream is pressure conveying, installation position can be without limitation.

The rotary motion of this example spool 10 is driven by driving device 4 (rack-and-pinion oscillating cylinder), and rack-and-pinion is swung The rotation angle of cylinder is 0-180 °, 0 ° of corresponding valve open state, 180 ° of corresponding valve closing states, and rack-and-pinion oscillating cylinder can pass through Pneumatic/hydraulic driving, driving torque is big, while being convenient to realize and automatically control.The driving method of spool 10 can also pass through it Its mode realizes that, if electric cylinder driving or lever mode are manual, this example is not listed all.

The axial position of spool 10 is adjusted when positioning sleeve I2 and positioning sleeve II13 is used to install, and makes the runner hole of spool 10 The entrance of 1011 and 14 valve bodies is to just.Limiting bracket 3 on positioning sleeve I2 is for mounting and positioning driving device 4.

The valve body 14 of this high temperature solid-state material plug valve, spool 10, gasket ring 7, inlet transforms pipe 1, discharge connection 12 are adopted With can the high metal material of heatproof, such as stainless steel 304,316 or steel alloy 12CrMoR, for corrosive materials using 304 or 316,12CrMoR can be used in non-aggressive material.

It should be understood that above-mentioned specific embodiment of the invention is used only for exemplary illustration or explains of the invention Principle, but not to limit the present invention.Therefore, that is done without departing from the spirit and scope of the present invention is any Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.In addition, appended claims purport of the present invention Covering the whole variations fallen into attached claim scope and boundary or this range and the equivalent form on boundary and is repairing Change example.
