Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of can the normal operation under rugged environment and maintainable high temperature resistant Unloading ball valve.
Background technique
High-temperature ball valve is shape metallic leak-proof structure, and the butterfly plate of high-temperature ball valve is installed on the diametric(al) of pipeline, in hard seal ball valve valve cylinder-shaped passage, the disc butterfly plate rotates around axis, angle of swing is between 0 ° ~ 90 °, and when rotating to 90 °, valve then is full-gear.High-temperature ball valve is used very extensive in steel industry.
The high-temperature ball valve of the former use in lime kiln is worked under the hot environment up to eight or nine hundred degree for a long time, can't effectively cool off high-temperature ball valve, and high-temperature ball valve is subject to the erosion of lime for a long time, the stuck phenomenon of dust stratification often occurs, cause the high-temperature ball valve sealing to be damaged and cause it to scrap.
Summary of the invention
The purpose of this utility model provides a kind of high-temperature water cooling Unloading ball valve, and this ball valve utilizes self water cooling and tapering hard sealing structure, under the hot environment of eight or nine hundred degree, can prolong the working life of ball valve when unloading lime, reduces production costs.
The purpose of this utility model is achieved through the following technical solutions:
A kind of high-temperature water cooling Unloading ball valve is characterized in that: this ball valve comprises valve casing, and the upper end of valve casing is connected with valve upper cover with the valve upper cover flange by the valve casing flange, is provided with loam cake water inlet and loam cake water outlet at valve upper cover; The lower end of valve casing is provided with adpting flange; Be provided with the tapered plug rod guidance cylinder of living at valve casing, the tapered plug bar of living is sleeved on tapered plug and lives in the rod guidance cylinder, and the live upper end of bar of tapered plug is connected with tapered plug, and the lower end of tapered plug bar alive is connected with cylinder; The tapered opening of tapered plug and valve upper cover is suitable; In tapered plug is lived bar, be provided with outlet pipe, be provided with the circulating water gateway at outlet pipe.
In the utility model, tapered plug bar alive is sleeved in the tapered plug rod guidance cylinder alive by top copper sheathing and bottom copper sheathing.Outside living bar, the tapered plug that is positioned at valve casing is provided with fixedly dust-proof cover and movable dust-proof cover.The tapered plug sealing surface adopts tapering firmly to seal, and tapering must be moderate, and tapering is the easy dust stratification of auger face too, and the too little sealing of tapering is not easy to guarantee.
It is short working life that the utility model utilizes self water cooling and the hard sealing of tapering to efficiently solve high-temperature ball valve, changes frequently problem, and greatly reduce cost of production.Every of cost of High-temperature cooling Unloading ball valve self-control is about 6000 yuan, and be about a year and a half working life, and outsourcing high-temperature ball valve cost is about 20000 yuan/, and average life was less than 2 months.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is outline drawing of the present utility model.
Embodiment
A kind of high-temperature water cooling Unloading ball valve described in the utility model is seen Fig. 1, and this ball valve comprises valve casing 5, and being connected with the valve upper cover flange and being connected with valve upper cover 2 by valve casing flange 4 in the upper end of valve casing 5, is provided with loam cake water inlet 1 and loam cake water outlet 17 at valve upper cover 2; The lower end of valve casing 5 is provided with adpting flange 6; Be provided with the tapered plug rod guidance cylinder 11 of living at valve casing 5, the tapered plug bar 13 of living is sleeved on tapered plug by top copper sheathing 9 and bottom copper sheathing 12 and lives in the rod guidance cylinder 11, and the live upper end of bar 13 of tapered plug is connected with tapered plug 18, and the lower end of tapered plug bar 13 alive is connected with cylinder 15; Tapered plug 18 is suitable with the tapered opening 19 of valve upper cover 2; In tapered plug is lived bar 13, be provided with outlet pipe 7, be provided with circulating water gateway 14 at outlet pipe 7.
Outside living bar 13, the tapered plug that is positioned at valve casing 5 is provided with fixedly dust-proof cover 8 and movable dust-proof cover 10.Tapered plug 18 sealing surfaces adopt tapering firmly to seal, and tapering must be moderate, and tapering is the easy dust stratification of auger face too, and the too little sealing of tapering is not easy to guarantee.
The high-temperature water cooling Unloading ball valve adopts cylinder to promote valve inner cone plug and moves up and down the realization valve switch, by the Stroke Control tapered plug of cylinder bar alive, thereby effectively controls the speed that unloads ash.
Circulating water is adopted in the design of the sealing surface of tapered plug in valve body and the valve, effectively reduces valve body self temperature, has overcome the drawback that traditional rubber seal is easily destroyed by high temperature.
Dust-proof cover is used for preventing that lime from entering in the tapered plug rod guidance cylinder alive, causes copper sheathing stuck by lime, can prolong the working life of High-temperature cooling Unloading ball valve.Adopt fixedly that dust-proof cover and movable dust-proof cover are to decide according to the stroke of cylinder, for the stroke that can make cylinder is fully used.
For the ease of loading and unloading and the maintenance of High-temperature cooling Unloading ball valve, tapered plug discrepancy water-cooling tube adopts internal thread to connect in the valve.
