Abstract
The utility model discloses a kind of forging wedge-type Elastic valve clacks, the flap includes half flap of a left side (1) and right half flap (2) using forging molding, left deformation slot semi-elastic and right deformation slot semi-elastic are machined at the mating surface of left half flap (1) and right half flap (2) respectively, left half flap (1) is fixedly connected by a mandrel (3) with right half flap (2) and constitutes a complete flap, and left deformation slot semi-elastic and right deformation slot semi-elastic is made to form a complete flexible deformation slot (6), the left side, right half flap (1, 2) several and on mandrel (3) are additionally provided with subtract and answer slot (4).The forging wedge-type Elastic valve clack of the utility model has many advantages, such as to be applicable in high temperature and high pressure environment, the design and manufacture that can be applicable in heavy-caliber gate valve and flexible deformation slot, and directly the processing is simple, highly promotes the use of.
Description
Technical field
The utility model relates to a kind of gate valve flaps, more particularly, to a kind of forging wedge-type Elastic valve clack.
Background technique
Currently, the flexible deformation slot of elastic Wedge Gate Valves flap is usually that grooving after casting and forming or forging is used to form；
Wherein, for casting and forming flap, due to being limited by casting itself, cause using the flap of casting and forming in high temperature
Use under high pressure occasion is increasingly restricted；And for the molding flap of grooving after forging, it is larger when facing bore
Valve when, on forging molding flap directly processing form flexible deformation slot, difficulty of processing is very big, and processes
Design requirement is also not achieved in the depth of flexible deformation slot out.
Utility model content
The technical problem to be solved by the utility model is to provide one kind to be suitable for high temperature and high pressure environment, is suitable for heavy caliber
The design and manufacture of gate valve and the flexible deformation slot forging wedge-type Elastic valve clack that directly the processing is simple.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of forging wedge-type Elastic valve clack, described
Flap includes half flap of a left side and right half flap using forging molding, is distinguished at the mating surface of half flap of left half flap and the right side
It is machined with left deformation slot semi-elastic and right deformation slot semi-elastic, left half flap is fixedly connected with structure by a mandrel with right half flap
At a complete flap, and left deformation slot semi-elastic and right deformation slot semi-elastic is made to form a complete flexible deformation slot.
Further, several are additionally provided on left and right half flap and mandrel subtract and answer slot.
The beneficial effects of the utility model are: the flap of the utility model is by half flap of a left side and right half using forging molding
Flap simultaneously welds to be formed by mandrel split, and is machined with respectively at the mating surface of left half flap and right half flap left semi-elastic
Slot and right deformation slot semi-elastic are deformed, when a complete flap is formed by welding by mandrel split in left half flap and right half flap
Afterwards, it can also be thus greatly reduced in the flexible deformation slot of one completion of composition at the mating surface of left half flap and right half flap
The difficulty that flexible deformation slot is directly processed on the forging flap of large bore valves, so that this forging wedge-type Elastic valve clack can be applicable in
In the design and manufacture of the larger gate valve of bore, while it can also be applicable in high temperature and high pressure environment；Therefore, the forging wedge-type of the utility model
Elastic valve clack had not only solved the problems, such as that casting and forming flap was easy to appear defect, but also solved forging flap and directly process elasticity change
The problem of shape slot hardly possible.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model forging wedge-type Elastic valve clack；
In the figure, it is marked as half flap of the left side 1-, half flap of the right side 2-, 3- mandrel, 4-, which subtracts, answers slot, 5- weld seam, 6 flexible deformation slots.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, the forging wedge-type Elastic valve clack of the utility model, including wedge-shaped flap, the wedge-shaped flap by
It is welded and to be formed by a mandrel split using half flap of a left side and right half flap of forging molding, left half flap and right half valve
Left deformation slot semi-elastic and right deformation slot semi-elastic are machined at the mating surface of valve respectively, left half flap and right half flap pass through one
Root mandrel, which is fixedly connected, constitutes a complete flap, and keeps left deformation slot semi-elastic and deformation slot composition one semi-elastic of the right side complete
Whole flexible deformation slot 6.
Slot 4 is answered as a preference, being additionally provided with several on left and right half flap 1,2 and mandrel 3 and subtracting；When left and right half
Flap is welded by mandrel split to form complete flap after, the weld seam 5 between left and right half flap and mandrel can also be shunk, from
And welding stress is generated between left and right half flap and mandrel, the utility model by being provided with left and right half flap and core in advance
Several on axis, which subtract, answers slot, can effectively absorb these welding stresses.
The flap of the utility model is welded by half flap of a left side and right half flap using forging molding and by mandrel split
It is formed, and is machined with left deformation slot semi-elastic and right deformation semi-elastic respectively at the mating surface of left half flap and right half flap
Slot, after a complete flap is formed by welding by mandrel split in left half flap and right half flap, also can half flap of a left side with
The flexible deformation slot of one completion of composition, thus greatly reduces the forged valve in large bore valves at the mating surface of right half flap
The difficulty of flexible deformation slot is directly processed on valve, so that this forging wedge-type Elastic valve clack can be suitably used for the design of the larger gate valve of bore
Manufacture, while it can also be applicable in high temperature and high pressure environment；Therefore, the forging wedge-type Elastic valve clack of the utility model had both solved casting
The problem of molding flap is easy to appear defect, but it is difficult to solve the problems, such as that forging flap directly processes flexible deformation slot.
It should be understood that the above-mentioned specific embodiment of the utility model is used only for exemplary illustration or explains this reality
With novel principle, without constituting limitations of the present invention.Therefore, in the spirit and scope without departing from the utility model
In the case of any modification, the equivalent replacement etc. made, should be included within the scope of protection of this utility model.
