Abstract
The invention relates to a large-caliber sleeve valve with an anti-rotation structure. The large-caliber sleeve valve of the invention comprises a valve body, a valve cap, a padding component, an actuating mechanism and a valve core, and is characterized in that an orifice sleeve is arranged in the valve body in a mode of being located by an excircle; the lower end part of a sleeve is matched with the inner bore of the orifice sleeve, the upper end part of the sleeve is matched with the valve body, and the sleeve is internally provided with the valve core which can make rectilinear motion relative to the sleeve; a standstill locking valve rod is in threaded connection with the valve core, an anti-rotation block is welded on the valve cap, the standstill locking valve rod and the valve core are arranged in the sleeve, a boss in the anti-rotation block on the valve cap is aligned with an outer groove on the standstill locking valve rod, and the upper end part of the standstill locking valve rod is connected with the actuating mechanism; and the actuating mechanism drives the standstill locking valve rod and the valve core to make lifting motion so as to regulate the flow of the valve. The invention can avoid oscillation caused by unbalanced torque which is generated on the valve core by media, simultaneously prevent the standstill locking valve rod from bending and cracking, has simple product structure, is safe and reliable and can prolong the service life of products.
Description
Technical field
The present invention 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 objective of the invention is to overcome the deficiencies in the prior art, a kind of large-caliber sleeve valve with rotation prevention structure is provided, it is simple in structure, has improved the reliability of telescoping valve, has prolonged the working life of product.
According to technological scheme provided by the invention, 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 invention: 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.
