Description

The known cork taps of the npii resin duct used in the trunk tar ducts, especially in wintertime, when the resin thickens and hardens, often fail and break down as a result of the valve plugs to its body.

The proposed device of the cork-type stopcock ensures its reliability in these conditions.

The advantages of the proposed device and the usefulness of its use in industry lies in the fact that the design of the crane provides for the possibility of its use as a universal purpose crane for the part of the main pipeline located between the valve and the furnace heads.

The attached drawing shows a tap in section, with the tap of the valve conventionally shown uncut. Numbers) drawing designate: / -casing; 2-sleeve; 3-flanges; 4-nrobku; 5 Packing NiTynep; 6-water tap shirt; 7-pod 011ip1 resin 1wire; 8 discharge lateral; 9-pipe to supply compressed air or steam; 10-channel in the sleeve body for compressed air of steam; // - pipeline for supplying heated water; 12-hole 1e for draining heated water from a water plane and; 13 nipples in a stopper for sealing rings; 4 — shown in dotted lines — an opening in a stopper — for resin; 15- hole in the plug for compressed air or steam; 16 fixing bolts; 17- abivka from asbestos 1 P1ura; 18-1appy cork; 19 is the square of the drive axle to put the drive lever on it; 20- welds; 21 sealing flange projections.

The crane is made with a water jacket 6 which is built in between the casing / and the bushing 2 and is intended for the bushing 2 of the ispoGKii 4.

tap and filled with running heated water coming into it from the cooling devices of the furnace.

The cork stopper 4 has two, located by an angle of 90, holes: the main 14-larger diameter, indicated by a dotted line, for the resin and the auxiliary 15-smaller diameter for compressed air or steam.

The water at Ruba 6 provides certain temperature conditions for the operation of the crane.

The purge (purge) or nrog) evanna located between the tap and the heads of some of the main railroad pipe is made through the opening 15. The presence of the gasket is 1, n. the protrusions 21 on the flanges 3 of the crane and the sealing nabnvkn 7 provides sealing valve.

In the case of nocazain in the drawing, the closure 4 of the speck 4 is open to the resin mixers through the opening 14, which flows from the supply resin line 7 to the discharge pipe 8, through which the resin is fed to the heads of the open-hearth furnace.

While the resin is being fed through the opening 14, the opening 15 is closed.

When the nrobki 4 is turned around its axis by 90, the rap will be open for supplying compressed air from the opening 15 and the knee box 1C to the compressed air from father of 1 year1: tse t |

At the time of delivery with an idler or a pair through the opening 15, the opening 14 remains closed.
