Description
Technical field
The utility model relates to a kind of hard seal ball valve.
Background technique
due to ball valve have double fluid to, resistance is little and open and close that rapid etc. a little metal seal ball valve is in extensive use and liquid or gas piping system, what mainly play is exactly the mobilization of conducting or cut-out liquid or gas; Ball valve need often carry out good maintenance in using process, but existing seal ball-valve valve body all adopts integral type to make, and causes the dismounting trouble, safeguards inconvenience; It is slow that driving mechanism opens and closes speed.
The model utility content
For addressing the above problem, the utility model proposes a kind of removable valve body, the hard seal ball valve of worm gear drive.
Hard seal ball valve of the present utility model, comprise valve ball, upper valve rod, worm gearing and right valve barrel; Described valve ball is arranged on right valve barrel inside, and left side is equipped with the left valve barrel be connected with right valve barrel; Be equipped with the valve seat combination part between described valve ball and left valve barrel and right valve barrel; Described valve ball bottom is connected with through the lower valve rod of right valve barrel bottom; Described lower valve rod bottom is provided with the bottom of installing with the right valve barrel sealed bottom; Described bottom downside is equipped with plug screw, and coaxial with bottom; Described right valve barrel top is equipped with upper cover; Described worm gearing is fixed on the right valve barrel top by support; Described upper valve rod is simultaneously through upper cover and right valve barrel top, and with worm gearing, with valve ball, is connected respectively; Be provided with the disk handle on described worm gearing.
Further, described valve seat combination part comprises spring, spring seat, graphite circle and valve seat.
Further, described right valve barrel is provided with respectively bottom pad, middle flange gasket and upper lid gasket with bottom, left valve barrel and the upper cover place of connection; Be provided with the plug screw pad between described plug screw and bottom.
Further, described upper valve rod and valve ball and worm gearing joint are respectively arranged with short flat key and long flat key.
Further, between described upper valve rod and upper cover, be filled with graphite, and the Gland sealing is arranged.
Further, described right valve barrel top right sidewall is equipped with nameplate.
The utility model compared with prior art, it has following beneficial effect: hard seal ball valve of the present utility model, adopted removable valve body to replace traditional integral valve body, working service is all very convenient, be both driving mechanism is upgraded to worm gear drive, really realized the fast fast effect of closing that opens, each parts joint of ball valve all adopts special seal ring, and sealability is also due to general hard seal ball valve.
