Abstract
The present invention relates to a kind of to stamp multilevel decompression ball valve core, and spool is made of sphere, orifice plate A, orifice plate B, orifice plate C and orifice plate D；It is machined with positioning step in the opposite position of sphere and orifice plate；Sphere and orifice plate are interference fit, and when assembling first heats sphere, then orifice plate A, orifice plate B, orifice plate C and orifice plate D are put into sphere successively and are welded as a whole.Endoporus on preceding three-level orifice plate, which is all made of, to be arranged with axis in 30 °, and the hole on afterbody orifice plate is to be parallel to axis, and 4 holes are arranged circumferentially on every grade of orifice plate.Since the region that liquidates be easy to cause the destruction to orifice plate, thickeied in the center of rear three-level orifice plate, to improve service life.The present invention is suitable under High Pressure Difference, the harsh operating mode that easily cavitates, compared with existing decompression ball valve core, has that simple in structure, processing cost is low, installation is easy, antihypertensive effect clear advantage.
Description
Technical field
It is the invention belongs to ball valve technical field, more particularly to a kind of to stamp multilevel decompression ball valve core.
Background technology
In industrial process control system, the operating mode that usually can be related to High Pressure Difference, easily cavitate.This operating mode can be to system
In various equipment belts carry out significantly damages：It is more than the noise of permitting deformation that acceleration, which generates the burn into of material, it is strong to cause
Vibration etc..When serious, equipment fault is resulted even in, in turn results in serious accident.This is all in industrial stokehold system
Wall is needed to exempt from system.For this present situation, current existing solution is typically multilevel decompression regulating valve or labyrinth type set
The straight stroke valves such as cylinder regulating valve, in addition, patent CN104676098A is related to a kind of labyrinth type multilevel decompression cavitation-preventive adjusting ball
Valve, although have the effect of it is good, since the manufacture difficulty of labyrinth type ball valve core is big, high processing costs, largely
On constrain the application range of angle stroke multistage decompression regulating valve.
Invention content
In view of the above shortcomings of the prior art, the object of the present invention is to provide a kind of to stamp multilevel decompression ball valve core,
It is primarily adapted for use in High Pressure Difference, under the harsh operating mode that easily cavitates, compared with existing decompression ball valve core, there is simple in structure, processing
At low cost, easy, the antihypertensive effect clear advantage of installation.
The purpose of the present invention is what is realized by using following technical scheme：
It is a kind of to stamp multilevel decompression ball valve core, be made of sphere, orifice plate A, orifice plate B, orifice plate C and orifice plate D；In order to
Positioning, is machined with positioning step in the opposite position of sphere and orifice plate respectively.Sphere is interference fit with orifice plate, in assembling
It needs first to heat sphere, then orifice plate A, orifice plate B, orifice plate C and orifice plate D is put into sphere successively and welded.
As the preferred technical solution of the present invention, the upper and lower end of the sphere is cylinder, and upper end opens that there are one sides
Slot, for the connection with ball-valve valve rod.
As the preferred technical solution of the present invention, 4 holes are circumferentially uniformly machined on each orifice plate；Add on orifice plate
The hole of work is in 30 ° with axis, and the hole processed on orifice plate A is parallel with axis；Orifice plate is thickeied in center, and thickness is orifice plate D
1.5 times.
The beneficial effects of the invention are as follows：Compared with the existing technology, sphere of the present invention, orifice plate be respectively adopted stainless steel casting,
Processing, by being welded as a whole；Endoporus on preceding three-level orifice plate is all made of with axis in 30 ° of arrangements, afterbody orifice plate
On hole be to be parallel to axis, and 4 holes are arranged circumferentially on every grade of orifice plate.Again since the region that liquidates be easy to cause device to hole
The destruction of plate is thickeied in the center of rear three-level orifice plate, to improve service life.The present invention is suitable for High Pressure Difference, easily cavitation erosion
Harsh operating mode under, compared with existing decompression ball valve core, have that simple in structure, processing cost is low, installation is easy, antihypertensive effect
Clear advantage.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and detailed description：
Fig. 1 is the structural schematic diagram of ball valve core of the present invention.
Wherein；1. valve body；2. orifice plate A；3. orifice plate B；4. orifice plate C；5. orifice plate D.
Specific implementation mode
As shown in Figure 1, a kind of to stamp multilevel decompression ball valve core, by sphere (1), orifice plate A2, orifice plate B3, orifice plate C4 with
And orifice plate D5 compositions are machined with positioning step in the opposite position of sphere 1 and orifice plate respectively in order to position；Sphere 1 and orifice plate
For interference fit, need first to heat sphere 1 in assembling, then successively by orifice plate A2, orifice plate B3, orifice plate C4 and orifice plate D5
It is put into sphere 1 and welds.
In the present embodiment, the upper and lower end of the sphere 1 is cylinder, and upper end is opened there are one square groove, is used for and ball valve
The connection of bar.It is circumferentially uniformly machined with 4 holes on each orifice plate；The hole processed on orifice plate B3, orifice plate C4 and orifice plate D5 and axis
Line is in 30 °, and the hole processed on orifice plate A2 is parallel with axis；Orifice plate A2, orifice plate B3, orifice plate C4 are thickeied in center, thickness
It is 1.5 times of orifice plate D5.
It is characteristic of the invention that it is simple in structure, processing cost is low, installation is easy, antihypertensive effect is apparent, can substitute existing
Labyrinth type multilevel decompression ball valve core be suitable under High Pressure Difference, the harsh operating mode that easily cavitates.
Above-described embodiment is only limitted to illustrate design and the technical characteristic of the present invention, and its object is to allow those skilled in the art
Member understands the technical solution and embodiment of invention, can not limit the scope of the invention accordingly.It is every according to the present invention
Equivalent replacement or equivalence changes made by technical solution, should be covered by the protection scope of the present invention.
