Abstract
The utility model relates to an improved structure for grinding the sealing surface of a valve. For the improved structure, the original manual grinding is substituted with electric grinding; the grinding speed is high; the ratio of ground particles passing through the sealing surface in unit time is high; a large quantity of metal is cut off; the labor intensity is lowered; the production efficiency is improved by above three times; and the grinding quality and efficiency are enhanced, therefore the quality and the efficiency of valve production are directly promoted.
Description
Technical fieldThe utility model relates to valve and makes the field, concrete relates to a kind of improvement structure that valve sealing face grinds that is used for.
Background technologyAlong with the continuous development of nuclear power field and petrochemical field, large bore valves production domesticization degree is also more and more higher.In the manufacturing of valve, grind and to occupy considerable status, the quality of valve there is remarkable influence.Valve seals by valve seat and flap.Therefore, the processing of flap and valve seat in the valve is the key that valve is produced.In order to guarantee the sealing property of valve, need grind its sealing surface.Lapping mode in the past all adopts hand lapping.For valve body, use disc shaped lapping tool usually, be placed on the sealing surface in the cavity, connect with Connection Block again and drive abrasive disk by the long handle handle and do to grind motion, such lapping mode since sealing surface in the valve body chamber, grinding ratio is difficulty; For flap, add clamping of workpieces with vice, with abrasive hand tool flap is ground, same Grinding Quality is often unstable, and production efficiency is low.
Summary of the invention
The utility model is at above technological deficiency, provides a kind of improvement to the grinding of valve sealing face.
The technical solution of the utility model is: a kind of improvement structure that is used for the valve sealing face grinding, grinding for valve body sealing surface, adopt electronic mode to be connected with hand held electric drill, comprise valve body, valve seat, positioning disk, abrasive disk, Connection Block, hand held electric drill, abrasive disk is positioned by positioning disk, and meanwhile fixed connecting base links to each other with hand held electric drill.
Sealing for the flap sealing surface, the electronic mode of same employing is connected with hand held electric drill, comprises vice, flap, positioning disk, abrasive disk, Connection Block, hand held electric drill, and flap is tightened by vice, abrasive disk is positioned by positioning disk, and meanwhile fixed connecting base links to each other with hand held electric drill.
Described hand held electric drill, maximum drilling diameter φ 23mm, rated voltage 220V, input power 1500W, rated speed 330r/min.
The beneficial effects of the utility model are: what valve sealing face ground improves one's methods, replaced original hand by the electrodynamic type grinding, grinding rate is fast, the abrasive grains of passing through on the sealing surfaces in the unit interval is than higher, the metal that cuts is also many, has reduced working strength of workers, enhances productivity more than 3 times, the quality of attrition process and the raising of efficient, thus the quality and benefits that valve is produced will directly have been promoted.

Fig. 1 is an electric grinding valve body sealing surface instrument schematic diagram.
Fig. 2 is an electric grinding flap sealing surface instrument schematic diagram.
Among Fig. 1,1, valve body 2, valve seat 3, positioning disk 4, abrasive disk 5, Connection Block 6, hand held electric drill; Among Fig. 2,1, vice 2, flap 3, positioning disk 4, abrasive disk 5, Connection Block 6, hand held electric drill.
The specific embodiment
Grinding for valve body sealing surface, adopt electronic mode to be connected with hand held electric drill, comprise vice 1, valve seat 2, positioning disk 3, abrasive disk 4, Connection Block 5, hand held electric drill 6, abrasive disk 4 is positioned by location 3 dishes, meanwhile fixed connecting base 5 links to each other with hand held electric drill 6, drives abrasive disk by hand held electric drill 6 and does the grinding motion.
Sealing for the flap sealing surface, the electronic mode of same employing is connected with hand held electric drill, comprise vice 1, flap 2, positioning disk 3, abrasive disk 4, Connection Block 5, hand held electric drill 6, flap 2 is by vice 1 chucking, abrasive disk 4 is positioned by positioning disk 3, meanwhile fixed connecting base 5 links to each other with hand held electric drill 6, drives abrasive disk by hand held electric drill 6 and does the grinding motion.
