Abstract
The invention discloses a fine grinding stainless high temperature and high pressure resistance hollow floating ball used for a pressure pipeline component. After being precisely grinded, the circular accuracy of the ball can reach 0.2 percent of the diameter of the floating ball. The hollow floating ball has the advantages that the accuracy of the floating ball is high, the sealing performance is good, and any spherical face can be taken as the sealing surface; formulary liquid is filled inside the floating ball, so that the floating ball is ensured to resist the high temperature and high pressure, the centralized abrasion can not be caused during the operating period, and the service life is long.
Description
Technical field
The present invention relates to a kind of metal hollow ball, especially a kind of fine grinding non-corrodible steel high temperature and high pressure resistant hollow floating ball that can be applicable to the pressure piping element.
Background technique
At present, the more common stainless steel hollow float in market mainly contains two kinds:
A kind of is to carry out the stainless steel hollow float that surface finish is handled to hollow float, and this polishing hollow spheres surface is light very, can't see weld mark, but ball float circularity is meticulous inadequately, is similar to elliptical shape, and the ball wall is very thin, and is in light weight.This polishing ball float generally only is suitable for decoration or cleaners and polishes etc. and requires undemanding utensil.
A kind of is the stainless steel hollow float that adopts roly-poly principle to process, and two hemisphere up and down that are about to different wall are welded into hollow float, the thin hemisphere of wall up, the hemisphere of wall thickness below, the cambered surface of utilizing lower semisphere is as sealing surface.This hollow float is mainly used in the valve industry, as main Sealing, because the ball float weld seam does not carry out depth treatment; Some scar during stretching; Ball circle precision is not high, poor sealing performance, and working life is very short; Externally during variation in pressure under the easy deformation, particularly HTHP working state.
Summary of the invention
For solving meticulous inadequately, the problem that can not high temperature high voltage resistant of existing stainless steel hollow float circularity, the invention discloses a kind of new process of stainless steel hollow float, aim to provide a kind of fine grinding non-corrodible steel high temperature and high pressure resistant hollow floating ball.
1, fine grinding non-corrodible steel high temperature and high pressure resistant hollow floating ball, its structure mainly is welded to form by episphere, lower semisphere jointly, it is characterized in that: the prescription liquid that high temperature high voltage resistant is housed between episphere and the lower semisphere.
2, fine grinding non-corrodible steel high temperature and high pressure resistant hollow floating ball, its characteristic one are that hollow spheres circle precision reaches floating ball diameter 2/1000ths.
3, fine grinding non-corrodible steel high temperature and high pressure resistant hollow floating ball, its characteristic two are that hollow float weight reaches buoyancy 1/2.
The concrete implementation of the present invention mainly is divided into following step:
1, adopts the numerical control hydraulic stretcher, be drawn into two semi-round balls that wait wall thickness to corrosion resistant plate;
2, cut edge through shaping, bore on the episphere top and open a 1.5mm pore;
3, adopt argon arc welding machine fixing two semi-round ball butt joint welding;
4, adopt the fully-automatic laser circular seam welder the disposable welded closed of hollow float;
5, it is inner to inject hollow float to doses prescription liquid, and spot welding closed vent hole;
6, preliminary working shaping, the weld mark when removing welding under remaining;
7, adopt centerless grinding machine that the stainless steel hollow float of shaping is carried out whole fine gtinding, reach 2/1000ths of floating ball diameter until ball circle precision.
The present invention compares maximum innovative point with original stainless steel hollow float:
1, ball float circularity has the highi degree of accuracy characteristics, and fineness reaches 2/1000ths of floating ball diameter, and sphere can both be as sealing surface arbitrarily;
2, ball float integral body such as has at the wall thickness characteristics, and is can whole sphere during proper functioning evenly stressed, can bear higher working pressure, improves working life;
3, prescription liquid is housed in the ball float, when the HTHP working state, the prescription vaporizing liquid impels internal pressure to increase, and reaches internal and external pressure balance, prevents the stressed generation distortion of ball float appearance.
4, ball float is through counterweight, and the weight of controlling each hollow float reaches 1/2 buoyancy, and corollary equipment can better be adjusted the service behaviour parameter, guarantees that equipment reaches the best effort effect.
Eventually the above, fine grinding non-corrodible steel high temperature and high pressure resistant hollow floating ball is applicable to the use equipment that requires precision higher, can be as accurate core open-shut device; The continuous conversion sealing surface of ability during work; Do not concentrate wear point, working life is quite long, good seal performance.
Description of drawings
Fig. 1 is the section of structure of fine grinding non-corrodible steel high temperature and high pressure resistant hollow floating ball;
Among Fig. 1, episphere (1), welding vent (2), center line weld seam (3), lower semisphere (4).
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
As shown in Figure 1, the withstand voltage hollow float of fine gtinding stainless steel mainly is made up of episphere (1), vent (2), center line weld seam (3), lower semisphere (4).At first, design semi-round ball drawing die is drawn into two semi-round balls that wait wall thickness, i.e. episphere (1) and lower semispheres (4) to corrosion resistant plate through the numerical control hydraulic stretcher; Cut edge respectively by design parameter, be drilled with a 1.5mm vent (2), make hollow spheres when welding, keep internal and external pressure balance at episphere (1) top; The employing argon protects electrode holder episphere (1) and lower semisphere (4) fixes with the triangular form butt welding, does not stay the slit; Then; Whole stainless steel hollow float is clamped on the fully-automatic laser circular seam welder worktable; Accomplish the disposable welded closed in slit between episphere (1) and the lower semisphere (4), treat after the hollow float cooling, it is inner to inject spheroid to the prescription liquid of certain proportional quantity from vent (2); Make the weight of whole ball float equal 1/2 water buoyancy, adopt argon to protect electrode holder vent (2) spot welding sealing after the counterweight; Next, adopt the automatic shaping machine that vent (2) solder joint and center line weld seam (3) are carried out shaping, preliminary working is got rid of up to all even weld; At last, the stainless steel hollow float after the shaping is put into automatic centerless grinding machine, evenly grind, reach 2/1000ths of ball circular diameter up to ball float free kick surface accuracy.
Through above production method; Can produce the highi degree of accuracy stainless steel hollow float of all size size; Not only ball circle precision is very high for no soldered crack, this hollow float element, can also high temperature high voltage resistant; Be to use the most perfectly core parts of equipment best kit, particularly type mechanical steam valve.
