Abstract
The utility model provides a ball valve machining device, and particularly relates to a valve flap grinding machine of a semi-ball valve. The valve flap grinding machine comprises a machine frame and a rotating disc arranged on the machine frame. A speed-adjustable driving motor and a swing motor drive a main shaft and the rotating disc to rotate relative to a valve flap. A swing crank drives a swing rod to rotate in the circumferential direction through an inclined hole which is formed in the crank and has a certain angle. Meanwhile, the swing rod stirs a valve flap supporting shaft to swing up and down in the circumferential direction in a grinding pot. Rotation of the grinding pot and circumferential swing of the valve flap are matched with each other. The valve flap grinding machine of the semi-ball valve is simple and novel in structure, high in automation degree, wide in applicant range and capable of being applied to grinding of valve flaps of different specifications.
Description
Technical field
The utility model is a kind of valve process equipment, particularly a kind of semisphere valve finishing machine for valve clack.
Background technology
Eccentric half-ball valve be utilize the action principle of eccentric distorted pattern make valve seal form lock tightly with separate, thereby realize positiver sealing and the fast opening and closing of valve.Because valve clack sealing surface is sphere, on sphere radius of turn difference a little, eccentric spherical curve is etc. and enters curve, in the time of valve-off, sealing sphere enter more close after valve seat tighter. form enough seal pressures, so semisphere valve sealing is reliable and stable.Because flap is wholecircle shape full tunnel, flow resistance is little, has good trafficability performance.
Semisphere valve also has higher wear-resisting, decay resistance, and can automatically remove the dirt on sealing surface while closing, simultaneously because sphere is etc. to enter its sealing station of curve and can wait into reach, there is the good rich effect of tasting of asking, long service life. because semisphere valve has above characteristic, be widely used in oil, chemical industry, metallurgical, electric power, the operating modes such as water supply. but the flap of eccentric half-ball valve and valve seat must have higher quality of fit, flap sealing sphere must have very little form error, for this energy mouth work to flap sphere need adopt polishing processing---the method for attrition process.
There is no at present and realize light processing---the grinder that is applicable to multiple specifications of grinding method.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of novelty simple in structure is provided, the semisphere valve finishing machine for valve clack that automaticity is high.
Technical scheme:
A kind of semisphere valve finishing machine for valve clack, comprise frame, be arranged at the rotating disc in frame, adjustable speed drive motors, oscillating motor drive main shaft and rotating disk to do relative rotation with flap, swinging bent axle drives swing arm to do circular-rotation by the inclined hole of certain angle in axle, swing arm is stirred flap back shaft and do upper and lower circle swing in grinding pot simultaneously, grinds the rotation of pot and the circle swing of flap and cooperatively interacts.
Described swing arm is provided with Compress Spring, and Compress Spring capable of regulating flap is to grinding pot thrust.
Described rotating disc and swing arm speed are adjustable, realize multiple combination.
The beneficial effects of the utility model:
1, semisphere valve finishing machine for valve clack of the present utility model, novelty simple in structure, automaticity is high, widely applicable, can apply with the flap of different size and grind;
2, semisphere valve finishing machine for valve clack of the present utility model, grinding precision is high.
