Description
Technical field
The utility model belongs to ball valve field, relates to stable transmission in a kind of opening and closing process in particular, can not produce the ball valve of relative sliding between rocking bar and spool.
Background technique
Ball valve is widely used in petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, the industries such as iron and steel, the spool of ball valve is the spheroid with passage, due to the reason of spheroid self structure, connection between spool and the rocking bar controlling ball valve opening and closing is the principal element determining ball valve open and close controlling transmission stability, in prior art, mostly be adopt to start a mounting hole at spool top, and be connected between rocking bar with mounting hole, and it is relative fixing fixedly to realize between rocking bar with spool mounting hole by mechanical seal box machinery, this connection for transmission mode, the shortcoming existed is when sealing and mechanical connection occurs slightly loosening, just relative sliding is there will be between rocking bar and spool mounting hole, make the rotation of rocking bar can accurately agonic drive valve core rotation, like this, ball valve just loses the control of stability opening and closing, affect the quality of ball valve and normal use, need to repair or replace parts, affect the normal work of ball valve or ball valve place system, cause damage.
Model utility content
The purpose of this utility model is to provide a kind of improved ball valve, and the connection that this ball valve controls between the rocking bar of ball valve opening and closing and ball valve core is reliable, and transmission stability is good, and transmission shift phenomenon can not occur.
A kind of improved ball valve of technical solutions of the utility model, comprise ball valve shell, valve pocket is provided with in described ball valve shell, in described valve pocket, spool is installed, described spool is the spheroid with passage, the central axis of described passage overlaps with sphere diameter, described valve core outer surface is provided with rocking arm mounting plane, the centerline axis parallel of described rocking arm mounting plane and passage, described rocking arm mounting plane is provided with two rocking arm mounting holes, rocking bar is connected and installed with in described rocking arm mounting hole, described rocking arm comprises two fixing rods be arranged in two rocking arm mounting holes, described two fixing rod upper ends are connected with fixed plate, described fixed plate is connected with rocking bar, described rocking bar outer cover is connected to pressing plate, plate is fixed bottom described pressing plate, described rocking bar top is connected with rocking handle.
Preferably, described rocking arm mounting plane is square, and described two rocking arm mounting holes are symmetrical arranged with a diagonal axis of foursquare rocking arm mounting plane.
Preferably, between described fixing rod, fixed plate, rocking bar, all employing is welded to connect.
Preferably, described pressing plate comprises sleeve and mounting plate, and described mounting plate is arranged at sleeve upper end, and it is outside and be fixed plate through ball valve shell that described jacket casing is connected to rocking bar, described mounting plate by screw and ball valve shell affixed.
A kind of improved ball valve of technical solutions of the utility model, plane and rocking arm mounting plane is processed at the spool top of sphere-like, and perforate and rocking arm mounting hole in the plane, the positioning handle being convenient to rocking arm mounting hole like this determines its hole depth, make the axes normal of two rocking arm mounting holes in the axis of spool upper channel, ensure that rocking arm mounting hole when spool is installed is vertical direction, and with a diagonal of foursquare rocking arm mounting plane axisymmetricly.
A kind of improved ball valve of technical solutions of the utility model, the fixing rod adapted with the aperture of rocking arm mounting hole and the degree of depth is set respectively in two rocking arm mounting holes, and weld with two fixing rods with fixed plate, make fixing rod, in an entirety between fixed plate and rocking bar, rocking bar rotates and drives fixing rod synchronous axial system, two fixing rods both can drive valve core rotation, two rocking arm mounting holes are set and the object be connected with rocking bar is exactly, as long as rocking bar and fixing rod rotate, spool will inevitably rotate, gap or the skew and changing of trace can not be there is in spool between fixing rod and rocking arm mounting hole, two relatively-stationary fixing rods and rocking arm mounting hole, effectively limit the revolute pair of fixing rod compared to mounting hole axis, ensure that the transmission between rocking bar and spool, make to there will not be between rocking arm and spool and relatively rotate or move.
A kind of improved ball valve of technical solutions of the utility model, at rocking bar outside socket pressing plate, the sleeve of pressing plate passes ball valve shell and contacts with fixed plate, the length of sleeve is greater than the distance of fixed plate end face distance ball valve shell upper surface, like this, when utilizing screw to be fixed on ball valve shell by the mounting plate on pressing plate, and downward clamping platen, make sleeve can be fixed plate downwards, ensure that fixed plate can completely deeply enter in rocking arm mounting hole, guarantee rocking bar, fixed plate and the relative fixing and transmission of fixing rod with spool further.
The utility model technology beneficial effect:
A kind of improved ball valve of technical solutions of the utility model, rocking bar, fixed plate, between fixing rod and spool, stable connection is reliable; can not relatively rotate between rocking arm and spool; after rocking arm turns an angle; spool will inevitably rotate equal angular; can not offset, and can guarantee that ball valve opening and closing is smooth, ensure that the normal work of ball valve.
