Abstract
The utility model discloses a floating ball linkage type control ball valve, and belongs to the technical field of valves. The control ball valve aims to solves the problems that an existing ball valve has poor structural sealing performance, matching between valve pieces is prone to getting stuck, and the existing ball valve is inconvenient to use. Binaural grooves are formed in the two ends of a spherical valve core installed in an inner cavity of a ball valve body. The interiors of the binaural grooves in the two ends of the spherical valve core are respectively provided with a center shaft, and the center shafts are inserted in shaft holes prefabricated in the two ends of the ball valve body. The position, located on the outer side of the ball valve body, of a shaft head of the center shaft is provided with a double-link-rod arm, and the shaft head of the center shaft is connected with the double-link-rod arm in a positioning mode. The positions, at the two ends of the spherical valve core, of the center shaft are respectively sleeved with one to three seal rings. Center shaft ring pieces are installed on the contact surfaces where center shaft bodies at the two ends rotate in cooperation with inner ports of the shaft holes of the ball valve body. Rod arm ring gaskets are installed in the connection gaps between the double-link-rod arm and shaft hole port walls of the ball valve body. The top of the double-link-rod arm is connected with a floating ball. The floating ball linkage type control ball valve is simple in structure, suitable for cutting off of media in a pipeline or allowing the media to be communicated and applicable to regulation and control of fluid.
Description
Technical field
The utility model belongs to a kind of ball valve of controlling in valve technology field.
Background technique
Ball valve is mainly used in blocking or connecting the medium in pipeline, also can be used for adjusting and the control of fluid, has been widely used in the fields such as oil, chemical industry, metallurgy, agricultural byproducts processing.Along with the manufacturing growing and extensive use of valve, the technical requirements of ball valve is also needed to improve constantly.In known technology, existing ball valve, mainly by being equiped with a spherical valve core with holes in ball valve body inner chamber, spherical valve core is connected with control handle, spherical valve core two ends are provided with valve seat, the sphere of spherical valve core directly contacts with the sealing surface of valve seat, and hole when valve open on spherical valve core and the axis parallel of valve form a passage; When valve closing, by control handle, spherical valve core being rotated, is throttle down by valve passage blocking-up.But limit by its structure, its sealing structure is poor, and often exists ball valve switch not in place in practical application, causes seepage, interconnects cooperation unreasonable between the parts of valve, there is large, the easy stuck phenomenon of rotational resistance, application life is low, also makes troubles to use.
Model utility content
In order to overcome the deficiencies in the prior art, solve existing ball-valve structure sealing poor, exist between valve member coordinate easily stuck, awkward problem.The object of the utility model is to provide a kind of simple and practical, and sealing structure is good, interconnects and coordinate closely rotation smooth and easy between the parts of valve, and application life is long, new-type control ball valve easy to use.
The technical scheme in the invention for solving the above technical problem is:
A kind of ball float interlock type control ball valve, it is provided with: ball valve body, spherical valve core, axis, duplex lever arm, ball float, the two ends of installing spherical valve core in ball valve body inner chamber are shaped with ears groove, in the ears groove at spherical valve core two ends, be equiped with respectively axis, the axis at spherical valve core two ends is inserted in the prefabricated axis hole in ball valve body two ends, and on the axis spindle nose at two ends, be positioned at that ball valve body outside is equiped with duplex lever arm and by nut by axis, duplex lever arm and ball valve body are located by connecting, be set with 1-3 road on the axis axis body at spherical valve core two ends in, Simmer ring and ball valve body axis hole wall are tightly connected, and be equiped with axis ring plate in coordinating with ball valve body axis hole internal orifice on the surface of contact rotating of two ends axis axis body, between being connected with ball valve body axle port wall, duplex lever arm is equiped with lever arm ring pad, the top portion of duplex lever arm connects ball float.
Above-mentioned ball float interlock type control ball valve, described duplex lever arm is U the single lever-type duplex lever arm that double armed lever becomes U-shaped receipts or other documents in duplicate pole composition, the top portion that the U-shaped cephalic par of duplex lever arm connects respectively the axis at ball valve body two ends, single pole connects ball float; Or adopt Y shape duplex lever arm; And the duplex lever arm of other adaptive type.
Above-mentioned ball float interlock type control ball valve, is equiped with sealing gasket between described nut and axis are connected.
When the utility model uses, according to designing requirement, ball valve, the load of ball float difference are arrived to controlled pipeline, instrument, unit etc., ball float is along with rise, the decline of controlled liquid level, and then connect and automatically control the unlatching of ball valve or close by duplex lever arm, block or connect the medium in pipeline.
Because the utility model design has adopted technique scheme, float valve, with to control ball valve in mating connection, has been solved to existing ball-valve structure sealing poor effectively, exist between valve member, coordinate easily stuck, awkward problem.Also show through testing result on trial for several times, it compared with prior art, have simple and practical, sealing structure is good, between the parts of valve, interconnect and coordinate the advantages such as closely rotation is smooth and easy, and application life is long, easy to use, the medium in pipeline is blocked or connects in the fields such as oil, chemical industry, metallurgy, agricultural byproducts processing that are applicable to, and the adjusting of fluid and control.
