Abstract
The utility model relates to a novel coke-oven valve body, belonging to the field of a coke-oven crude gas guiding-out system. The novel coke-oven valve body comprises a valve body, a valve body press cover, a pull rod end press cover, a pull rod and a reverse turning plate, wherein a rotary shaft of the reverse turning plate controls the reverse turning plate to rotate, the pull rod end press cover and the valve body adopt a split type structure and are fastened and connected by screws; one end of the rotary shaft of the reverse turning plate is packaged in the valve body press cover; a refueling cup is arranged on the valve body press cover; the valve body press cover and the valve body are sealed by a high-pressure rubber pad; a layer of graphite packing seal is also additionally arranged between the pull rod end press cover and the valve body; and the press cover is made of A3 steel. The novel coke-oven valve body has the benefits that the valve body not only enhances the sealing effect and effectively eliminates the leakage of crude gas, but also reduces the labor intensity of workers; and besides, by optimizing the material of the press cover, the service life of the valve body is prolonged, the cost performance of the valve body is improved, the consumption of spare parts is reduced, and the production cost is lowered.
Description
Technical field:
The utility model relates to a kind of new Type Coke Oven valve body, belongs to coal oven dithio-gas guiding system field.
Background technique:
The raw coke oven gas that produces in the coke furnace carbonization chamber flows to the subsequent treatment operation by the raw coke oven gas guiding system, in the raw coke oven gas guiding system, valve body plays a part very important, mainly be connection and the cut-out that realizes coal gas system by valve body, play a very important role guaranteeing the direct motion tool of producing.The valve body that uses all is that a whole set of technology is equipped with design now, and the complete complete sealing configuration of right and wrong passes through packing_seal between gland and the valve body rotating plate shaft.Between terminal gland of valve body rotating plate shaft and rotating plate shaft, use the graphite packing_seal, but when collecting main pressure fluctuate or coke oven be in middle and advanced stage packing ignition loss just can be when big from axle envelope leakage raw coke oven gas, so both befouling environment had been wasted valuable coal gas resource again.And not only exist raw coke oven gas to leak at valve body rotating plate shaft drag link end, and the drag link end gland adopts integral structure, when need changing, sealed material graphite packing just pull bar, gland all need be unloaded down like this, just can carry out the replacing of packing, but owing to be in the hot environment for a long time, and space for maintenance is narrow and small, makes that the unloading process of gland is difficult unusually, and worker's labor intensity is very big.And the former design material of gland is HT15-33, and fragility is bigger, occurs local fracture easily and cause the connecting thread shading to lose efficacy in the replacing process, has increased worker's labor intensity, and has wasted spare part again, has increased cost of production.
The model utility content:
Given this, the purpose of this utility model is exactly to leak seriously in order to overcome existing valve body rotating plate shaft two ends raw coke oven gas, and shortcoming such as worker's maintenance, operation labor intensity are big, and working life is short provides a kind of new Type Coke Oven valve.
The technical solution of the utility model is achieved in that
A kind of new Type Coke Oven valve body comprises valve body body 1, valve body gland 2, drag link end gland 3, pull bar 4 and turnover panel, the running shaft 5 control turnover panel rotations of turnover panel, and wherein: drag link end gland 3 and valve body body 1 adopt split-type structural, are fastenedly connected with screw.
Further, an end of the running shaft 5 of turnover panel is wrapped in the valve body gland 2.
Further, valve body gland 2 is provided with and adds lubricating cup 6.
Further, be provided with high pressure sealing rubber pad 7 between valve body gland 2 and the valve body body 1.
Further, three-layer sealed graphite packing is set between drag link end gland 3 and the valve body body 1.
Further, the gland material is the A3 steel.
The beneficial effects of the utility model are: this valve body has not only strengthened sealing effect, has stopped the leakage of raw coke oven gas effectively; And reduced worker's labor intensity; And by optimizing the gland material, prolonged the working life of valve body, improved the valve body cost performance, reduced spare parts consumption, reduced production cost.
Description of drawings:
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model drag link end gland and valve body body connection diagram.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of new Type Coke Oven valve body, comprise valve body body 1, valve body gland 2, drag link end gland 3, pull bar 4 and turnover panel, the running shaft 5 control turnover panel rotations of turnover panel, wherein: it is split type that the utility model drag link end gland structure has made vertical symmetry into by original integral type, and with screw with its up and down two halves carry out fasteningly effectively, make that its intensity is constant.And with drag link end gland 3 28mm that has been pressed into shorten length in the valve body body 1, utilize this useful space, on original two-layer basis, increased one deck sealing graphite packing again, by increasing sealed material, strengthen sealing effect, more effectively reduced the leakage of raw coke oven gas.Rotating plate shaft 5 ends adopt all-sealed gland structure with valve body gland 2 connecting places, and rotating plate shaft 5 is wrapped in the valve body gland 2, have effectively stopped the gas leakage between valve body gland 2 and the rotating plate shaft 5.And set up on valve body gland 2 positive tops and to add lubricating cup 6, be convenient to that rotating plate shaft 5 is carried out continuous lubrication and safeguard.Valve body gland 2 and valve body body 1 joint effectively seal by high pressure sealing rubber pad 7, and the raw coke oven gas of having stopped valve body rotating plate shaft 5 ends leaks.Transform like this and be convenient to the worker in the process of changing packing, as long as the fastening primary screw of two halves is up and down disassembled, and the screw at gland two ends drawn off and can divide two halves to take off on gland, and need not be difficult more difficultly with two whole having disassembled of king bolt, operating time can be reduced to a present people in 40 minutes 10 minutes by two original people, make things convenient for operation, reduced worker's labor intensity.And in new valve body, the material of valve body gland 1 and drag link end gland 3 is optimized for the A3 steel by original cast iron, the anti-performance of beaing is better, strengthened the intensity of gland, in the process of changing packing, reduced the replacing that damages the new gland that causes owing to gland like this, both reduced worker's labor intensity, reduce the consumption of spare part again, reduced cost of production effectively.
The above only is embodiment of the present utility model; but be not so promptly limit scope of patent protection of the present utility model; equivalent structure that every utilization the utility model specification and accompanying drawing content are done changes, and all is included in the claim that the utility model contains.
