Abstract
The invention discloses a valve rod nut on a valve. The valve rod nut is lengthened, so that the two ends of the valve rod nut appropriately project out of a valve rod nut bracket on a valve cover respectively; the highest point of a valve rod thread of the valve rod nut projecting out of the two end parts of the valve rod nut bracket on the valve cover is provided with a sewage disposal groove; the formed sewage disposal groove cuts the valve rod thread on the valve rod nut; and on an incision, a valve rod nut sewage disposal cutter is formed by the cut valve rod thread on the valve rod nut. During opening and closing of a valve, the valve rod nut sewage disposal cutter is used for actively clearing dirt on a screw rod passing through the valve rod nut sewage disposal cutter, and cleared dirt is discharged from the sewage disposal groove, so that dirt on the screw rod is cleared.
Description
Technical field
The present invention relates to the Stem Mut on the valve, is a kind of Stem Mut that can in use clear up dirt on the screw rod.
Background technique
Dirt on the valve rod of valve often gets into Stem Mut, causes the switch valve difficulty, even clogs valve rod and Stem Mut gap, can't switch valve.
Summary of the invention
In order to address the above problem, the invention provides a kind of remove contamination novel Stem Mut of cutter and dump tank of Stem Mut that has.
Implementation of the present invention is; The lengthening Stem Mut; Make the Stem Mut support on the suitably outstanding separately valve gap in Stem Mut two ends, the threaded stem peak place of the Stem Mut of the Stem Mut support two end portions on outstanding valve gap leaves dump tank, the threaded stem on the Stem Mut of the dump tank cut-out process of leaving; In incision, threaded stem on the Stem Mut of cut-out forms the Stem Mut cutter of removing contamination.Such Stem Mut structure, in switch valve, the Stem Mut cutter of removing contamination is initiatively removed through the dirt on its screw rod, and the dirt of removing is discharged from dump tank, thereby solves dirt jam Stem Mut and valve lever clearance problem.
Description of drawings
Fig. 1 is first embodiment's the sectional view schematic representation of the implementation of Stem Mut of the present invention.
Fig. 2 is second embodiment's the sectional view schematic representation of the implementation of Stem Mut of the present invention.
Fig. 3 is the 3rd embodiment's the sectional view schematic representation of the implementation of Stem Mut of the present invention.
Embodiment
Like Fig. 1, Fig. 1 is first embodiment's the sectional view schematic representation of the implementation of Stem Mut of the present invention, and schematic representation is that handwheel is not followed the Stem Mut that valve rod moves.Stem Mut by Stem Mut body 1, down blow groove 2, go up dump tank 3 and the Stem Mut cutter 4 of removing contamination and form.Stem Mut body 1 leave up and down two dump tanks, down blow groove 2 and last dump tank 3 up and down respectively.Down blow groove 2 cuts off through the threaded stem on the Stem Muts of otch with last dump tank 3, and in incision, the threaded stem on the Stem Mut of cut-out forms the Stem Mut cutter 4 of removing contamination.Such Stem Mut structure, in switch valve, Stem Mut is removed contamination, and initiatively removing is through the dirt on its screw rod for cutter 4, and the dirt of removing is discharged from last dump tank 3 or down blow groove 2, thereby solves dirt jam Stem Mut and valve lever clearance problem.
Like Fig. 2, Fig. 2 is first embodiment's the sectional view schematic representation of the implementation of Stem Mut of the present invention, and schematic representation is that handwheel is not followed the Stem Mut that valve rod moves.Stem Mut by Stem Mut body 1, down blow groove 2, go up dump tank 3 and the Stem Mut cutter 4 of removing contamination and form.Stem Mut body 1 leave up and down two dump tanks, down blow groove 2 and last dump tank 3 up and down respectively.Down blow groove 2 cuts off through the threaded stem on the Stem Muts of otch with last dump tank 3, and in incision, the threaded stem on the Stem Mut of cut-out forms the Stem Mut cutter 4 of removing contamination.Threaded stem on the Stem Mut of this structure has been divided into two-part up and down.Such Stem Mut structure, in switch valve, Stem Mut is removed contamination, and initiatively removing is through the dirt on its screw rod for cutter 4, and the dirt of removing is discharged from last dump tank 3 or down blow groove 2, thereby solves dirt jam Stem Mut and valve lever clearance problem.
Like Fig. 3, Fig. 3 is first embodiment's the sectional view schematic representation of the implementation of Stem Mut of the present invention, and schematic representation is that handwheel is followed the Stem Mut that valve rod moves.Stem Mut by Stem Mut body 1, down blow groove 2, go up dump tank 3 and the Stem Mut cutter 4 of removing contamination and form.Stem Mut body 1 leave up and down two dump tanks, down blow groove 2 and last dump tank 3 up and down respectively.Down blow groove 2 cuts off through the threaded stem on the Stem Muts of otch with last dump tank 3, and in incision, the threaded stem on the Stem Mut of cut-out forms the Stem Mut cutter 4 of removing contamination.Such Stem Mut structure, in switch valve, Stem Mut is removed contamination, and initiatively removing is through the dirt on its screw rod for cutter 4, and the dirt of removing is discharged from last dump tank 3 or down blow groove 2, thereby solves dirt jam Stem Mut and valve lever clearance problem.
Though the above embodiment of the present invention is described in detail, it should be appreciated by those skilled in the art, can reach the various distortion of identical purpose with the present invention and substitute, also in this protection domain.
