Abstract
The utility model discloses a kind of general forging of new 1500-2500 pounds DN3/DN4 self-sealing gate valve stop valves, including main valve body forging, abutted flange, described main valve body forging both sides are symmetrically arranged with abutted flange, meanwhile, oblique arm main valve body forging centre position is provided with head cover engaging structure；Described main valve body forging, abutted flange, head cover engaging structure are solid forging structure；Described main valve body forging overall structure is that mid diameter is big, and both sides diameter is little.The beneficial effects of the utility model：This apparatus structure is simple, low production cost；This patent carries out forging monolithic molding by forging technology, then carries out post-production and become finished product, and its structural manufacturing process is simple, puts into little, and defect is few, and quality is obtained effective guarantee；Pollution environment is little, and while productivity effect is effectively improved, effect on environment is little.
Description
Technical field
This utility model is related to a kind of general forging of self-sealing gate valve stop valve, more particularly to a kind of new 1500-2500
The general forging of pound DN3/DN4 self-sealing gate valve stop valves.
Background technology
At present, the general forging blank species of self-sealing gate valve stop valve on existing market is a lot, but great majority are all
Main valve body is forging for main valve body and is processed valve body, or one piece casting by welding manner；Casting and human weld
Technique is required to larger Factory Building and more workman, and investment is big, and operation is more, complex manufacturing, and pollutes environment, and blank
Allowance is big, wastes big；Meanwhile, cast member often finds to scrap which because of casting flaw in process, to making product
Cost up, quality cannot ensure.
Content of the invention
For the shortcoming of existing self-sealing gate valve stop valve blank, this utility model provides a kind of new 1500-2500
The general forging of pound DN3/DN4 self-sealing gate valve stop valves.To achieve these goals, the measure taken by this utility model：
A kind of general forging of new 1500-2500 pounds DN3/DN4 self-sealing gate valve stop valves, including main valve body forging, right
Acting flange, described main valve body forging both sides are symmetrically arranged with abutted flange, meanwhile, oblique arm main valve body forging interposition is installed
It is equipped with head cover engaging structure；
Described main valve body forging, abutted flange, head cover engaging structure are solid forging structure；Described main valve body forging
Overall structure is that mid diameter is big, and both sides diameter is little.
The beneficial effects of the utility model：This apparatus structure is simple, low production cost；This patent is carried out by forging technology
Monolithic molding is forged, then carries out post-production and become finished product, its structural manufacturing process is simple, input is little, and defect is few, and quality can be had
Effect is ensured；Pollution environment is little, and while productivity effect is effectively improved, effect on environment is little.
Description of the drawings
Fig. 1, this utility model structural representation.
Specific embodiment
A kind of general forging of new 1500-2500 pounds DN3/DN4 self-sealing gate valve stop valves, as shown in figure 1, including master
Valve body forging 1, abutted flange 2, described 1 both sides of main valve body forging are symmetrically arranged with abutted flange 2, meanwhile, oblique arm main valve
1 centre position of body forging is provided with head cover engaging structure 3.In the actual implementation process of patent, described main valve body forging 1, right
Acting flange 2, head cover engaging structure 3 are solid forging structure, and defect is few, and quality is obtained effective guarantee；Meanwhile, described main valve
1 overall structure of body forging is that mid diameter is big, and both sides diameter is little, effectively strengthens valve mechanism intensity according to actually used situation.
In process, blanking unitary solid blank first；Secondly, then it is molded into corresponding mould by large pressing machine
Shape, obtains needing profile blank, that is, obtain main valve body forging 1, abutted flange 2, head cover engaging structure 3 for solid forging structure
The general forging of 1500-2500 pound DN3/DN4 self-sealing gate valve stop valves；Finally, by 1500-2500 pound DN3/DN4 self sealss
The general forging of gate valve stop valve becomes finished product valve partses by later stage machining again.This patent its simple structure, produces into
This is low；This patent carries out forging monolithic molding by forging technology, then carries out post-production and become finished product, its structural manufacturing process letter
Single, input is little, and defect is few, and quality is obtained effective guarantee；Pollution environment is little, to environment while productivity effect is effectively improved
Affect little.
The simple change of those ordinary skill in the art and replacement are all within protection domain of the present utility model.
