Description
Technical field
The utility model belongs to valve field, especially a kind of worm gear drive highi degree of accuracy flange butterfly.
Background technique
Use at engineering pipeline transportation art valve is very extensive, the basic structure of valve is co-axial seal setting-in valve seat in valve body now, valve rod is radially installed on valve body, on valve rod in valve body, be fixedly mounted with dish plate, dish plate coordinates with valve base sealing, thereby dish plate rotation or movement under the driving of valve rod open and close the runner in valve seat.Valve body outer radial is shaped with a plurality of flange plates for being connected with pipeline, is shaped with bolt mounting holes on flange plate.At present, the valve that some control accuracies are had relatively high expectations is controlled by worm-and-wheel gear, but existing valve mechanism parts are more, easily damages, and causes working life shorter.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of worm gear drive highi degree of accuracy flange butterfly of reasonable in design, simple in structure, easy to operate, long service life is provided.
The utility model solves its technical problem and takes following technological scheme to realize:
A worm gear drive highi degree of accuracy flange butterfly, comprises valve body, valve rod, valve seat, dish plate and handle Direct box, at valve body middle part, one valve rod is radially installed, and this valve rod upper end is stretched out valve body and is coaxially installed with one handle; In valve body, be axially installed with valve seat, dish plate is radially installed on the valve rod in valve seat, the outer wall at the axial two ends of valve body is all coaxially shaped with a flanged plate, on this flanged plate, spaced radial is evenly equipped with a plurality of bolts hole, it is characterized in that: the valve rod upper end in described Direct box is coaxially fixed with a worm gear, one side outer wall of this worm gear is engaged with the made teeth of a side of a horizontally disposed worm screw, and the made teeth of opposite side of this worm screw are driven by rotatable handle; Worm gear opposite side Direct box outer wall interval two spacing jackscrews are installed, Direct box outer wall is stretched out in spacing jackscrew one end, the other end directly stretches to worm screw outer wall.
And described valve seat is the one-body molded cylinder barrel shaped structure of making of rubber, valve seat middle part outer wall is coaxially shaped with a bulge loop, and is all shaped with bulge loop in the axial two ends of valve seat outer rim, and this bulge loop is inlaid in the made mounting groove in the axial two ends of valve body.
And described valve rod is positive six prism structures, valve plate is coaxially inlaid in the made regular hexagon valve rod mounting hole in dish plate middle part, and valve rod lower end is coaxially installed with thrust bearing on; Dish plate is double-sided symmetrical structure, wraps up valve rod completely, and dish plate outer rim is through the micro-hemisphere face of polishing treatment.
Advantage of the present utility model and good effect are:
The deformation effects such as 1, the support performance of the rubber gasket of this butterfly valve is good, and firmly stable, simple and compact for structure, adjusting function is good, guarantees to support moment not yielding again, and valve seat is not yielding, and tolerance is little, the expansion upheaval of valve seat are little, the long service life of valve seat.
2, valve rod lower end is provided with thrust bearing, prevents valve rod tenesmus distortion, reduces the resistance of rotation, makes to control more flexible.
3, the utility model is simple in structure, not fragile, long service life, and also structural strength is high, and good seal performance, easily controls, and moment of torsion resistance is little, and simple in structure, and the installation of valve part is simple, long service life.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model;
Fig. 2 be Fig. 1 in cut open right elevation.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A worm gear drive highi degree of accuracy flange butterfly, comprises valve body 5, valve rod 4, valve seat 7, dish plate 8 and handle Direct box 1, if accompanying drawing 1 is to as shown in accompanying drawing 2, at valve body middle part, one valve rod is radially installed, and this valve rod upper end is stretched out valve body and is coaxially installed with one handle; In valve body, be axially installed with valve seat, dish plate is radially installed on the valve rod in valve seat.
The outer wall at the axial two ends of valve body is all coaxially shaped with a flanged plate 6, and on this flanged plate, spaced radial is evenly equipped with a plurality of bolts hole, for being connected with piping flange.
Innovative point of the present utility model is:
Valve rod upper end in described Direct box is coaxially fixed with a worm gear 9, and a side outer wall of this worm gear is engaged with the made teeth of a side of a horizontally disposed worm screw 10, and the made teeth of opposite side of this worm screw are driven by rotatable handle 3; Worm gear opposite side Direct box outer wall interval two spacing jackscrews 2 are installed, Direct box outer wall is stretched out in spacing jackscrew one end, the other end directly stretches to worm screw outer wall, spacing jackscrew is corresponding valve opening or the limit position of closing respectively.
Described valve seat is the one-body molded cylinder barrel shaped structure of making of rubber, and valve seat middle part outer wall is coaxially shaped with a bulge loop 12, and is all shaped with bulge loop in the axial two ends of valve seat outer rim, and this bulge loop is inlaid in the made mounting groove in the axial two ends of valve body.And valve seat interior surface is uniformly coated with protective layer, this protective layer extends to the end face at the axial two ends of valve body, effectively prevents cut-off corrosion valve.
This valve seat construction is simple, effectively prevents that valve seat from moving axially, good stability, and also middle part is shaped with that to strengthen the valve seat intensity of bulge loop large, avoids the distortion of valve seat protuberance.
Described valve rod is positive six prism structures, and valve plate is coaxially inlaid in the made regular hexagon valve rod mounting hole in dish plate middle part, and valve rod lower end is coaxially installed with thrust bearing 11 on, increases and controls flexibility, and prevent valve rod tenesmus; Dish plate is double-sided symmetrical structure, wraps up valve rod completely, the rotation under the twisting force of valve rod of dish plate, and dish plate outer rim, through the micro-hemisphere face of polishing treatment, reduces operational torque.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
