The butterfly valve is characterized by that the valve body is a general diameter flange welded body with high temperature resistance standard; the circumference surface of the valve plate is a chamfer angle of 45 degrees in reverse symmetry, of which the center line and the center line of the valve shaft form an included angle A; the valve shaft is provided with a matched plane for using with the valve plate, of which the upper part is provided with a seal pressing sleeve and of which the lower part is provided with a matched hole for mounting the lower seal screw plug and the valve body, are connected and fixed by the holes on the bolt and the valve plate surface and are connected to the butterfly valve regulating and fixing mechanism. The utility model is suitable for the hot work environment of the industrial furnace under the temperature of between 500 and 700 DEG C, thereby especially solving the problem of locking or deadlocking phenomenon of the valve body and the valve plate of the butterfly valve under the hot work environment and also effectively solving the problem of external leakage of fuel gases by the clearance of the valve shaft and the valve housing.
Description
Technical field
The utility model belongs to industrial furnace fuel-burning equipment control system field, and particularly a kind of the card prevents leaking hard seal welding butterfly valve.
Background technique
The hardness seal butterfly valve device that present known industrial furnace fuel-burning equipment control system adopts all is that the cast moulding butterfly valve that the professional valve plant that buys on market produces replaces.Specialty butterfly valve manufacturer makes the butterfly valve product by adopting casting method, material generally is casting or gray cast iron, not only preparation process does not meet environmental requirement, and it is not only comparatively coarse but also operating ambient temperature range is little to be useful on the industrial furnace product, generally at-10 ℃～80 ℃.The fluid origin butterfly valve of extraordinary material, as: stainless steel, molybdenum two titaniums and monel metal butterfly valve, operating ambient temperature range is also only-40 ℃～305 ℃ scopes, the used butterfly valve of industrial furnace fuel-burning equipment control system, as: the working environment of heating gas is 250 ℃～350 ℃ scopes, and industrial furnace fuel-burning equipment control system flue emission control butterfly valve operating ambient temperature can reach 500 ℃～700 ℃ scopes.Especially the butterfly valve of the manual wafer type of casting method manufacturing is worked under thermal environment, and valve body and valve plate have deformation, block, stuck situation often takes place, and influence industrial furnace and normally move.The valve shaft of particularly general casting butterfly valve and the gap of valve pocket, the inflammable gas of air, coal gas in the continuous leakage pipe in whole process of production, befouling environment but also fire hidden danger is arranged not only, injure simultaneously operator healthy, cause the business property loss.For solving the above problem that exists in the known technology promptly is purpose of the present invention.
Summary of the invention
The utility model is for solving the above technical problem that exists in the known technology, and provide a kind of the card to prevent leaking hard seal welding butterfly valve, the technological scheme that the utility model is taked is: it comprises butterfly valve adjusting fixed mechanism 3, form by valve body 1, valve plate 2, valve shaft 4, last sealed pressing sleeve 5, lower seal screw plug 6, it is characterized in that valve body 1 is high temperature resistant standard latus rectum flange welding body; The circumferential surface of valve plate 2 becomes symmetrical reverse chamfering 2
1With 2
2Be 45 degree, its center line becomes included angle A with the center line of valve shaft 4, and the match plane 4 of installation usefulness of and valve plate 2 is arranged on the valve shaft 4
1With its top a sealed pressing sleeve 5 is arranged, the hole 4 that the bottom has a lower seal screw plug 6 to match with valve body 2 and install
2, by the hole 2 on bolt 7 and the valve plate 2 plate faces
3Be connected and fixed, regulate fixed mechanism 3 with butterfly valve again and be connected.
The utility model has also adopted following technical measures:
Advantage that the utlity model has and good effect:
The utility model adapts to the needs of modern science industrial furnace fuel-burning equipment control system, make hard seal welding butterfly valve with plate welding technology technology, be suitable for 500～700 ℃ of working environments of industrial furnace high-temperature, solved effectively with the casting butterfly valve and substituted drawback and the defective that is produced.Solved butterfly valve especially when the high-temperature work environment production operation, valve body and valve plate block, the generation of stuck situation.Solved simultaneously valve shaft and valve pocket gap effectively to external leakage inflammable gas and tar etc.,, ensured that operator are healthy preventing befouling environment, avoid fire hidden danger, simple in structure, operation is convenient, guaranteed air demand accurately and reliably and stability, improved manufacturing efficiency greatly.

Embodiment
In order further to understand content of the present utility model, characteristics and effect, and conjunction with figs. 1 is described in detail as follows: with latus rectum φ 100 is that example is described as follows: become the standard nominal diameter with 10mm thick-walled seamless steel pipes welding processing, closely cooperate and be pressed in the corresponding steel flanges dish, weld bond becomes 1/4 circular arc, and is not only attractive in appearance but also firm.
The valve body external diameter is more bigger than valve body inside nominal diameter, and valve plate center line around side is made 45 ° of chamferings of opposite both direction, and valve plate is fixed on the valve shaft and valve body vertical plane included angle A=6～9, and the valve plate chamfering contacts big with valve interior wall and the gap is little, lets out rate in can reducing.
Valve shaft twines the metallic graphite carbon packing up and down can prevent the gap problem that leaks, needn't annotate lubricating grease, greasy property is strong, and it is high temperature resistant, known butterfly valve controlling mechanism 3 is adopted in control, make 10 teeth, per 1 tooth may command valve plate is opened 1/10 angle, dial is fixed on the valve plate, on two holes of dish, garden of central siphon, the handle front end has the location crown, spring and auxiliary-handle, press auxiliary-handle valve plate operating grip and can rotate freely and unclamp auxiliary-handle handle crown and insert dial tooth guiding, the opening angle of valve plate normal valve is 0 °～90 °, in the rate of letting out be 0.1%～0.5% operating temperature-40 ℃～700 ℃, can be made into series standard nominal size product according to the production usage requirement, also configurable retarder and motor opening and closing except manually.
