Abstract
The utility model is related to a kind of 600LB valves bottom gatings.The shortcomings that 600LB valves 45 ° of running gate systems of old technology is:Cast supervisorWater injection pipeCast supervisor is big, and water injection pipe is small, and casting easy tos produce the casting flaws such as slag inclusion, trachoma, shrinkage porosite, shrinkage cavity.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, and the caliber of the main gate spool is less than the caliber of water injection pipe.The utility model cast supervisor is less than water injection pipe bore, can reduce flow velocity, reduces impact of the molten steel to sand mold, and change flange and valve body middle chamber riser position and size, reduces the casting flaws such as casting slag inclusion, trachoma, promotes casting quality.
Description
Technical field
The utility model is related to a kind of 600LB valves bottom gatings.
Background technology
The shortcomings that 600LB 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.
Casting flaw.
Utility model content
Purpose of the utility model is to solve problems of the existing technology, provide a kind of flexible concealed swimming pool peace
Full ladder, autostairs can be moved upwards up to the top of supporting rack by when contraction, simple in structure, safe to use, conveniently.
The technical solution adopted in the utility model is：A kind of 600LB 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
Diameter.
The caliber of the main gate spool is 60mm, and the caliber of the water injection pipe is 70mm.
Three insulation blind risers are set at the top of the lumen of the valve castings, and the caliber of each insulation blind riser is 220mm.
Three exhaust pipes are also set up at the top of the lumen of the valve castings.
Two symmetrical insulated feeders are respectively set above two end flanges of the valve castings and middle flange.
The caliber of the insulated feeder is 220mm.
The utility model cast supervisor is less than water injection pipe bore, can reduce flow velocity, reduces impact of the molten steel to sand mold, and change
Become flange and valve body middle chamber riser position and size, reduce the casting flaws such as casting slag inclusion, trachoma, promotes casting quality.
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：
As shown in Figure 1, a kind of 600LB valves bottom gating, including main gate spool 1, the end of main gate spool 1 are logical
It crosses transverse tube and is separately connected two water injection pipes 2, two water injection pipes are respectively classified into two piping connection valve castings from bottom to top again
End flanges, the caliber of main gate spool are less than the caliber of water injection pipe.The caliber of main gate spool is 60mm, the caliber of the water injection pipe
For 70mm.Three insulation blind risers 4 are set at the top of the lumen of valve castings, and the caliber of each insulation blind riser is 220mm.Valve
Three exhaust pipes 5 are also set up at the top of the lumen of casting.It is respectively set above two end flanges of valve castings and middle flange
Two symmetrical insulated feeders 3.The caliber of insulated feeder is 220mm.
The utility model cast supervisor is less than water injection pipe bore, can reduce flow velocity, reduces impact of the molten steel to sand mold, and change
Become flange and valve body middle chamber riser position and size, reduce the casting flaws such as casting slag inclusion, trachoma, promotes casting quality.
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.
