Description
Technical field
The utility model relates to high-accuracy fine finishining valve field, is a kind of choke valve flap Split type welded knot Structure. specifically
Background technology
Choke valve is to control the valve of fluid flow by changing throttling section or chock length.By choke valve and unidirectional
Valve parallel connection is then combined into one-way throttle valve.Choke valve and one-way throttle valve are easy flow control valves, in dosing pump hydraulic pressure
In system, choke valve and overflow valve coordinate, and can constitute three kinds of Metering Flow Control Circuits, i.e. in-line Metering Flow Control Circuits, oil return line
Metering Flow Control Circuits and bypass throttling speed governing system.Choke valve does not have flow negative feedback function, it is impossible to which compensation is by load change institute
The speed for causing is unstable, is typically only used for load change less or to the less demanding occasion of speed stability.
Structure such as Fig. 2, Ran Houzai that traditional choke valve flap is generally forged using one piece casting shaping or integral type
Design size is worked into, Fig. 1 is seen.Such global design complex geometry and huge structure, for cast flapper, its cavity
For meeting the requirement of intensity requirement and casting technique, often the thickness of cavity design and valve body wall thickness are suitable, not only waste of materials
And cause technique also more complicated, and for forging structure its turning process of integral type require higher.Therefore ask for above-mentioned
Topic is the object of this utility model research.
Utility model content
The purpose of this utility model is to provide a kind of choke valve flap Split type welded structure, the choke valve flap split
New design structure of the welded structure for choke valve flap, replace conventional throttle valve flap generally shaped using one piece casting or
The structure of person's integral type forging, new design geometrical form are simple, and structure is little, is easy to cast, with respect to the forging of integral type
Structure its turning process requires relatively low, and during the manufacturing, yields is high, can material-saving shorten man-hour, secondly as sealing
Face is finally individually to carry out turning, grinding, so can be guaranteed for the sealing property of valve.
The technical solution of the utility model is：A kind of choke valve flap Split type welded structure, including the throttling of flap
Portion and sealing, the restriction are the stamping forming " u "-shaped part of stainless steel materials, and the end face of the " u "-shaped part both sides respectively sets
There is wave tooth, the sealing is a surface plate, and the surface plate both sides are respectively provided with one can be mutual with wave tooth on " u "-shaped part
Second wave tooth of engagement, the surface plate both sides are hypotenuse, and the hypotenuse of the surface plate both sides is provided with sealing ring, the plane
Plate is welded in side with " u "-shaped part, and the " u "-shaped part bottom is provided with a pressure compensation opening.
Compared with prior art, the beneficial effects of the utility model are that the choke valve flap Split type welded structure is throttling
The new design structure of valve flap, the knot for replacing conventional throttle valve flap generally to forge using one piece casting shaping or integral type
Structure, new design geometrical form are simple, and structure is little, is easy to cast, and forging structure its turning process of relative integral type is wanted
Ask relatively low, yields is high during the manufacturing, can material-saving shorten man-hour, secondly as sealing surface is finally individually to carry out
Turning, grinding, so can be guaranteed for the sealing property of valve.
Description of the drawings
Fig. 1 is choke valve flap Split type welded structural representation.
Fig. 2 is traditional one piece casting shaping or integral type forging structure schematic diagram.
Specific embodiment
It is that features described above of the present utility model and advantage can be become apparent, special embodiment below, and coordinate accompanying drawing,
It is described in detail below, but this utility model is not limited to this.
With reference to legend 1, a kind of choke valve flap Split type welded structure, the restriction 1 and sealing 2 including flap, institute
Restriction 1 is stated for the stamping forming " u "-shaped part 11 of stainless steel materials, the end face of 11 both sides of " u "-shaped part is respectively provided with wave tooth
12, the sealing 2 is a surface plate 21, and 21 both sides of the surface plate are respectively provided with one can be with wave tooth 12 on " u "-shaped part 11
Intermeshing second wave tooth 22,21 both sides of the surface plate are hypotenuse 23, and the hypotenuse of 21 both sides of the surface plate is provided with close
Seal 24, the surface plate 21 are welded in side with " u "-shaped part 11, and 11 bottom of " u "-shaped part is provided with a pressure compensation opening 13.
New design structure of the choke valve flap Split type welded structure for choke valve flap, replaces conventional throttle valve flap generally to adopt
The structure that is forged with one piece casting shaping or integral type, new design geometrical form are simple, and structure is little, is easy to cast,
Require relatively low with respect to forging structure its turning process of integral type, during the manufacturing, yields is high, can material-saving shorten work
When, secondly as sealing surface is finally individually to carry out turning, grinding, so can be guaranteed for the sealing property of valve.
Flap is divided into 2 liang of parts of sealing 1 and restriction, welding is then carried out and is combined into one reprocessing sealing surface,
Restriction 2 can adopt stainless steel materials punch forming, and its sheet metal thickness can be according to nominal pressure, inside nominal diameter, material
The technical parameters such as the service life of corrosion rate and valve determine, and process a pressure compensation opening in its end, and sealing 1 is adopted
Welded with restriction after solid forging is rough turn, such material-saving that is designed to shortens man-hour, secondly as sealing surface
It is finally individually to carry out turning, grinding, so can be guaranteed for the sealing property of valve.
The foregoing is only preferred embodiment of the present utility model, all according to this utility model claim done equal
Deng change and modification, should all belong to covering scope of the present utility model.
