Specific embodiment
With reference to embodiment, the specific embodiment of the present invention is further described.
A kind of processing technology of water supply ball valve ball core, comprises the following steps that,
A, the ball valve ball core for obtaining diameter slightly larger than demand size is molded by injection molding machine；
B, the ball valve ball core in step A is machined out, obtains the ball valve ball core of rounding, size qualification；
C, machine cylinder is ground, water and several grinding beads, the grinding bead submergence are housed in the grinding machine cylinder
In water；The ball valve ball core of step B is placed in grinding machine cylinder, stirs evenly and ball valve ball core is made to be ground bead completely
Covering；Ball valve ball core be ground completely bead covering, just can guarantee grinding effect, avoid because in process of lapping ball valve ball core with grind
Bead is ground under the extruding of interaction force, so that ball valve ball core exposes the surface and partial mill bead exposes the surface, is generated
Dry friction leads to the problem of grinding quality difference.
D, start grinder, ball valve ball core ground polishing finished product core in grinding machine cylinder.
More specifically, the material of ball valve ball core is PVC, the grinding bead is that diameter is that two kinds of polishings of 4cm and 5cm are high
The mixture of fibrous gypsum bead is in order to improve grinding effect, so that core surface is more smart using the bead grinding of two kinds of specifications
Carefully.
Bead is ground preferably using the grinding bead for polishing high fibrous gypsum material, and the revolution for grinding machine cylinder is 900-1000
Rev/min, when grinding, is 30-40 minutes a length of.Why using the bead for polishing high fibrous gypsum material, because we test it is several other
The abrasive media of material, as a result such as:
Stainless steel ball: since surface itself is too smooth, grinding effect is bad instead, and weighs again, too to grinder load
Greatly.
Bead: the problem as stainless steel ball.
Ceramic bead: grinding effect is undesirable, and itself serious wear.
CPVC/UPVC bead: material hardness itself is inadequate, and grinding effect is undesirable.
Polish high fibrous gypsum bead: grinding effect is good, itself abrasion loss very little can be repeatedly used for a long；Component is gently to grinding
The load of machine is small, and electricity consumption is few, save the cost.
Handled through the above method: by grinding core compared with machine/Vehicle Processing core under the irradiation of light surface have it is similar
The gloss of mirror surface, sense of touch are more smooth.Through pressure test, each size ball valve pressure-bearing at least 2 hours under 1.6MPa pressure criteria
Have no that ball valve has droplet exudation.Ball valve pressure testing results of the core by the grinding ball valve not ground far better than core.
