Abstract
The utility model is related to a kind of 2500LB valves running gate systems.The shortcomings that 2500LB valve old technology center line bottom gatings, is on riser root collection sand top box surface, flows to latus rectum quick sand, and casting easy tos produce the casting flaws such as slag inclusion, trachoma, shrinkage porosite, shrinkage cavity, causes casting qualified rate low, and film making qualification rate is：78 89%.It is characterized by comprising main gate spool, the main gate spools to be separately connected valve body further through two water injection pipes in left and right for the utility model, and the water injection pipe is inserted into inside the wall thickness of valve flowing channel, and the runner is in convoluted.The beneficial effects of the utility model are：Gate spool is uniform, and the convolution reduction flow velocity in cavity runner reduces impact, casting flaw etc. of the molten steel to sand mold, promotes casting quality, qualification rate of making film：94 99% and yield rate：72%.
Description
Technical field
The utility model is related to a kind of 2500LB valves running gate systems.
Background technology
The shortcomings that 2500LB valve old technology center line bottom gatings is:Cast supervisorWater injection pipe
Keep molten steel flow speed too fast, molten steel impacts greatly sand mold, and cavity sand washing is serious, and broken sand caused by impact floats to top box, makes
Case surface flows to latus rectum quick sand, and riser root collection sand top box surface flows to latus rectum quick sand, casting easy to produce slag inclusion, trachoma,
The casting flaws such as shrinkage porosite, shrinkage cavity cause casting qualified rate low, and film making qualification rate is：78-89%.
Utility model content
Purpose of the utility model is to solve problems of the existing technology, provide 2500LB valve running gate systems,
Impact, casting flaw etc. of the molten steel to sand mold are reduced, casting quality is promoted, qualification rate of making film：94-99% and yield rate：72%.
The technical solution adopted in the utility model is：A kind of 2500LB valves running gate system, it is characterised in that poured including master
Note pipe, the main gate spool are separately connected valve body further through two water injection pipes in left and right, and the water injection pipe is inserted into valve body stream
Inside the wall thickness in road, the runner is in convoluted.
The water injection pipe is located at 45 ° of runner latus rectum.
The disc-shaped convolution of runner is arranged in the wall thickness of valve flowing channel.
The main gate spool and water injection pipe are 80mm.
The insulated feeder that the end flanges top setting bore of the valve body is 220mm.
The insulated feeder that the lumen top setting bore of the valve body is 260mm.
The insulated feeder of the two symmetrical bore 240mm in middle flange top setting left and right of the valve body.
The beneficial effects of the utility model are：Gate spool is uniform, and convolution reduction flow velocity, reduces molten steel in cavity runner
To impact, the casting flaw etc. of sand mold, casting quality is promoted, qualification rate of making film：94-99% and yield rate：72%.
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 2500LB valves running gate system as shown in Figure 1, including main gate spool 1, main gate spool is further through left and right two
A water injection pipe 2 is separately connected valve body, and water injection pipe is inserted into inside the wall thickness of valve flowing channel, and the runner is in convoluted.Water filling
Pipe is located at 45 ° of runner latus rectum.The disc-shaped convolution of runner is arranged in the wall thickness of valve flowing channel.Main gate spool and water injection pipe
It is 80mm.The insulated feeder 5 that the end flanges top setting bore of valve body is 220mm.Bore is arranged in the lumen top of valve body
For the insulated feeder 4 of 260mm.The insulated feeder 3 of the two symmetrical bore 240mm in middle flange top setting left and right of valve body.Valve
The insulated feeder 6 of the rear upper setting 240mm of body.
The water injection pipe of the utility model is inside the wall thickness of valve flowing channel, because the valve wall thickness of 2500LB is thicker, note
Water pipe is located at 45 ° of runner latus rectum, and there are no condensations, liquid condition flowing when molten steel has just enter into valve chamber, is flowing
Rotational flow inside the wall thickness of road latus rectum.Gate spool is uniform, and the convolution reduction flow velocity in cavity runner reduces molten steel to sand mold
Impact, casting flaw etc. promote casting quality, qualification rate of making film：94-99% and yield rate：72%.
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.
