Abstract
The utility model provides a large caliber sleeve valve provided with an anti-rotation structure. The sleeve valve comprises a valve body, a valve cover, a packing component, an actuating mechanism and a valve core, the sleeve valve is characterized in that: a throttling bushing is positioned with the cylinder to be installed in the valve body, the lower end of the sleeve cooperates with the inner hole of the throttling bushing, the upper end of the sleeve cooperates with the valve body, a valve core is disposed in the sleeve, the valve core can perform a linear motion relative to the sleeve, the rotation-stopping valve rod and the valve core are in a threaded connection, the anti-rotation block is welded to the valve cover, the rotation-stopping valve rod and the valve core are installed in the sleeve, the internal boss of the anti-rotation block on the valve cover aligns the external groove on the rotation-stopping valve rod, the rotation-stopping valve rod upper end is connected with the actuating mechanism, the actuating mechanism drives the rotation-stopping valve rod and the valve core to perform an elevating motion so as to adjust the flow of the valve. The large caliber sleeve valve in the utility model can eliminate oscillation brought by unbalanced torque generated upon valve rod by medium; and prevent rotation-stopping valve rod from being bended or fractured, the sleeve valve is also advantaged by simple structure, safety and reliability, as well as prolonging service life of product.
Description
Technical field
The utility model relates to a kind of large-caliber sleeve valve, especially a kind of large-caliber sleeve valve with rotation prevention structure.
Background technique
Along with economic development, the improving constantly of industrial automation controlling level, therefore to executive component important in the process control---the degree of regulation of modulating valve and the requirement of reliability are also in continuous raising.Existing sleeve adjusting valve does not all increase the design of valve rod anti-rotation, this design is little to the usability influence of the valve of latus rectum less (DN≤300), but usability obvious effect to the valve of latus rectum big (DN＞300), because medium can produce bigger uneven moment of torsion to spool, this causes the spool vibration probably, the screw thread that valve rod is connected with actuator produces loosening, thereby influence the product adjusting function, even might cause the generation of situations such as valve rod bending deflection, fracture, package unit is stopped, cause the tremendous economic loss.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of large-caliber sleeve valve with rotation prevention structure is provided, and it is simple in structure, has improved the reliability of telescoping valve, has prolonged the working life of product.
The technological scheme that provides according to the utility model, described large-caliber sleeve valve with rotation prevention structure, comprise valve body, valve gap, filler assembly, actuator and spool, feature is: also comprise the valve body pad, sleeve, orifice sleeve, bonnet gasket, the spline valve rod, anti-switch block and spool, described orifice sleeve is contained in the valve body with the cylindrical location, the underpart of described sleeve cooperates with the orifice sleeve endoporus, the upper end portion of sleeve cooperates with valve body, sleeve and valve body, use the valve body pad between the valve gap respectively, the bonnet gasket sealing, be provided with spool in the sleeve, spool is the sleeve moving linearly relatively, between described spline valve rod and the spool with being threaded, and it is fastening with straight pin, described anti-rotation block welding is on valve gap, and described spline valve rod and spool are contained in the sleeve, and the anti-switch block internal boss on the valve gap is aimed at the outer grooves on the spline valve rod, described spline valve rod upper end portion links to each other with actuator, and actuator drives the spline valve rod, spool moves up and down the flow with regulating valve.
Described valve gap is provided with seal plug.Seal with filler assembly between described valve gap and the spline valve rod.
Advantage of the present utility model: be provided with anti-switch block on valve gap, the guide ledges on the described anti-switch block matches with guiding groove on the spline valve rod; The vibration that the uneven moment of torsion that can avoid medium that spool is produced brings; Avoided the crooked or fracture of spline valve rod simultaneously, product structure is simple, and is safe and reliable, prolonged the working life of product.
