Abstract
The utility model relates to a kind of pair of stamp multilevel decompression ball valve core, spool is made of sphere, orifice plate A, orifice plate B, orifice plate C and orifice plate D；Positioning step is machined 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 successively put into sphere and are welded as a whole.Inner hole 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 utility model is suitable under High Pressure Difference, the harsh operating condition that easily cavitates, compared with existing decompression ball valve core, has that structure is simple, processing cost is low, installation is easy, antihypertensive effect clear advantage.
Description
Technical field
The utility model belongs to ball valve technical field, in particular to a kind of pair of stamp multilevel decompression ball valve core.
Background technique
In industrial process control system, the operating condition that usually can be related to High Pressure Difference, easily cavitate.This operating condition can be to system
In various equipment belts carry out significantly damages: accelerate to generate the burn into of material be more than the noise of permitting deformation, cause it is strong
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 status, current existing solution is usually 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, processing cost is high, largely
On constrain the application range of angle stroke multistage decompression regulating valve.
Utility model content
In view of the above shortcomings of the prior art, the purpose of the utility model is to provide a kind of pair of stamp multilevel decompression ball valves
Core is primarily adapted for use in High Pressure Difference, under the harsh operating condition that easily cavitates, compared with existing decompression ball valve core, have structure simple plus
Work is at low cost, installation is easy, antihypertensive effect clear advantage.
The purpose of this utility model is achieved by the following technical solution:
A kind of pair of stamp multilevel decompression ball valve core, is 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 and orifice plate are interference fit, in assembling
It needs first to heat sphere, then orifice plate A, orifice plate B, orifice plate C and orifice plate D is successively put into sphere and welded.
As the optimal technical scheme of the utility model, the upper and lower end of the sphere is cylinder, and upper end is provided with one
Square groove, for the connection with ball-valve valve rod.
As the optimal technical scheme of the utility model, 4 holes are circumferentially uniformly machined on each orifice plate；Orifice plate
The hole of upper processing and axis are in 30 °, and the hole processed on orifice plate A is parallel with axis；Orifice plate is thickeied in center, with a thickness of hole
1.5 times of plate D.
The beneficial effects of the utility model are: compared with the existing technology, the utility model sphere, orifice plate are respectively adopted stainless
Steel casting, processing, by being welded as a whole；Inner hole on preceding three-level orifice plate, which is all made of, to be arranged with axis in 30 °, last
Hole on grade orifice plate is to be parallel to axis, and 4 holes are arranged circumferentially on every grade of orifice plate.Again since the region that liquidates is easy to make
The destruction of pairs of orifice plate is thickeied in the center of rear three-level orifice plate, to improve service life.The utility model is suitable for high pressure
Under difference, the harsh operating condition easily to cavitate, compared with existing decompression ball valve core, with structure is simple, processing cost is low, installs just
Easily, antihypertensive effect clear advantage.
Detailed description of the invention
The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
Fig. 1 is the structural schematic diagram of the utility model ball valve core.
Wherein；1. valve body；2. orifice plate A；3. orifice plate B；4. orifice plate C；5. orifice plate D.
Specific embodiment
As shown in Figure 1, a kind of pair of stamp multilevel decompression ball valve core, by sphere (1), orifice plate A2, orifice plate B3, orifice plate C4 with
And orifice plate D5 composition is machined with positioning step in the opposite position of sphere 1 and orifice plate respectively to position；Sphere 1 and orifice plate
It for interference fit, needs 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 provided with a square groove, is used for and ball valve
The connection of bar.4 holes are circumferentially uniformly machined 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.
The utility model is characterized in that structure is simple, processing cost is low, installation is easy, antihypertensive effect is obvious, can substitute
Existing labyrinth type multilevel decompression ball valve core is suitable under High Pressure Difference, the harsh operating condition easily to cavitate.
Above-described embodiment is only limitted to illustrate the design of the utility model and technical characteristic, and its object is to allow the skill of this field
Art personnel understand the technical solution and embodiment of utility model, can not limit the protection scope of the utility model accordingly.It is all
It is equivalent replacement or equivalence changes according to made by technical solutions of the utility model, should all covers the protection model in the utility model
Within enclosing.
