Abstract
The utility model is related to a kind of 900LB valves bottom gatings.The old running gate system of 900LB valves, riser root collection is husky, and casting easy tos produce the casting flaws such as slag inclusion, trachoma, shrinkage porosite, shrinkage cavity, and the film making qualification rate of old technology is：85 94%.It is characterized by comprising main gate spools for the utility model, the end of the main gate spool is separately connected two water injection pipes by transverse tube, described two water injection pipes are respectively classified into two piping connection valve castings end flanges from bottom to top again, the caliber of the main gate spool is less than the caliber of water injection pipe, dreg collecting slot is respectively set in two end flanges of the valve body and the top of middle flange, and the dreg collecting slot is located on each flange between the riser being arranged and the riser being arranged on valve lumen.The utility model increases the dreg collecting slot between three side flanges and valve body middle chamber riser, reduces the casting flaws such as collection sand and slag inclusion at casting flange and valve seat, promotes casting film making qualification rate and yield rate, and film making qualification rate is：92 98%.
Description
Technical field
The utility model is related to a kind of 900LB valves bottom gatings.
Background technology
The shortcomings that 900LB valves 45 ° of running gate systems of old technology is:Cast supervisorWater injection pipeCast supervisor
Greatly, water injection pipe is small, keeps molten steel flow speed too fast, and molten steel impacts greatly sand mold, and cavity sand washing is serious, and broken sand caused by impact is upwards
Case floats, and makes top box surface, flows to latus rectum quick sand, and riser root collection is husky, and casting easy tos produce slag inclusion, trachoma, shrinkage porosite, shrinkage cavity etc.
The film making qualification rate of casting flaw, old technology is：85-94%.
Utility model content
Purpose of the utility model is to solve problems of the existing technology, provide a kind of 900LB valves bottom filling
Running gate system can reduce impact of the molten steel to sand mold, reduce the casting flaws such as casting slag inclusion, trachoma.
The technical solution adopted in the utility model is：A kind of 900LB valves bottom gating, it is characterised in that including
The end of main gate spool, the main gate spool is separately connected two water injection pipes by transverse tube, and described two water injection pipes are divided into not
It is divided into two piping connection valve castings end flanges from bottom to top, the caliber of the main gate spool is less than the pipe of water injection pipe
Dreg collecting slot is respectively set in diameter, two end flanges of the valve body and the top of middle flange, and the dreg collecting slot is located at each
Between the riser being arranged on flange and the riser being arranged on valve lumen.
The caliber of the main gate spool is 80mm, and the caliber of the water injection pipe is 100mm.
The insulated feeder being arranged on three side flange of valve is respectively two.
The bore for the insulated feeder being arranged on end flanges is 240mm.
The bore that the insulated feeder on middle flange is arranged is 220mm.
The riser being arranged on valve lumen is four insulation blind risers, and the bore of insulation blind riser is 200mm.
The utility model cast supervisorWater injection pipeFlow velocity is reduced after recoil, reduces molten steel and sand mold is rushed
It hits, reduces the casting flaws such as casting slag inclusion, trachoma, increase the dreg collecting slot between three side flanges and valve body middle chamber riser, reduce casting
Collect husky at part flange and valve seat is with casting flaws, promotion casting film making qualification rate and yield rate, film making qualification rates such as slag inclusions：
92-98%.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
In the following with reference to the drawings and specific embodiments, the utility model is expanded on further：
A kind of 900LB valves bottom gating as shown in Figure 1, including main gate spool 1, the main gate spool
End is separately connected two water injection pipes 2 by transverse tube, and described two water injection pipes are respectively classified into two pipelines from bottom to top and connect again
Valve castings end flanges are connect, the caliber of the main gate spool is less than the caliber of water injection pipe, two end face methods of the valve body
Dreg collecting slot 4 is respectively set in the top of blue and middle flange, and the dreg collecting slot is located at the riser and valve being arranged on each flange
Between the riser being arranged on lumen.
The caliber of main gate spool is 80mm, and the caliber of the water injection pipe is 100mm.Guarantor on three side flange of valve is set
Warm riser 3 is respectively two.The bore for the insulated feeder being arranged on end flanges is 240mm.Guarantor on middle flange is set
The bore of warm riser is 220mm.The riser being arranged on valve lumen is four insulation blind risers 5, the bore of insulation blind riser
For 200mm.
The utility model cast supervisorWater injection pipeFlow velocity is reduced after recoil, reduces molten steel pair
The impact of sand mold reduces the casting flaws such as casting slag inclusion, trachoma, increases the collection slag between three side flanges and valve body middle chamber riser
Slot reduces the casting flaws such as collection sand and slag inclusion at casting flange and valve seat, promotes casting film making qualification rate and yield rate, film making conjunction
Lattice rate is：92-98%.
Listed above is only specific embodiment of the utility model, and the utility model is not limited to above embodiment,
It is acceptable that there are many deformations.Those skilled in the art directly can export or associate from content disclosed by the utility model
All deformations, be considered as the scope of protection of the utility model.
