Abstract
The utility model discloses a device used for the connection between a valve rod and a valve clack of a stop valve, wherein, the valve clack is provided with a cylindrical cavity used for accommodating the end part of the valve rod, a ring-shaped groove is arranged on the inner wall of the cylindrical cavity, a groove ring is arranged on the valve rod opposite to the ring-shaped groove, a steel ball is arranged inside a ring-shaped cavity formed by the ring-shaped groove of the valve clack and the groove ring of the valve rod, the valve clack is provided with a through hole that is communicated with the ring-shaped groove; since the ring-shaped cavity formed by the ring-shaped groove of the valve clack and the groove ring of the valve rod is provided with the steel ball, the direct friction between the metals during the relative rotation between the valve rod and the valve clack is converted into the sliding friction of the steel ball, and the valve rod is more flexible and easy to operate, and at the same time, the service life of the stop valve is prolonged, thereby the utility model has high social value and high market popularization value.
Description
Technical field
The utility model relates to a kind of stop valve, specifically, relates to a kind of valve rod and flap connection set of stop valve.
Background technique
At present, the valve rod of common stop valve and flap Placement, generally be to be provided with groove at valve rod and flap joint, in the groove corresponding part of flap and valve rod three through holes are set, the stationary positioned screw is set in through hole positions valve rod, though this mode also can realize being rotationally connected of stop valve, but in practical operation, because set screw and valve rod are the direct friction between metal and the metal, so it is dumb to exist valve rod to rotate, and operates heavy, serious wear, stop valve short shortcoming in working life.
The model utility content
The purpose of this utility model provides a kind of valve rod and flap connection set of operating light, flexible, as can effectively to improve stop valve working life a kind of stop valve.
For achieving the above object, the technological scheme that the utility model adopted is: a kind of valve rod of stop valve and flap connection set, comprise valve rod and flap, it is characterized in that: described flap has the cylindrical cavity that is used for holding the valve rod end, described cylindrical cavity inwall is provided with annular groove, described valve rod and corresponding part, annular groove position are provided with the groove ring, be provided with steel ball in the formed toroidal cavity of groove ring of the annular groove of described flap and valve rod, described flap is provided with the through hole that communicates with annular groove.
Below be further improvement in the technical proposal:
Have in the described through hole and be used for the plug of shutoff through hole.
Beneficial effect: the utility model is taked above technological scheme, have the following advantages: owing to be provided with steel ball in the formed toroidal cavity of annular groove of the annular groove of flap and valve rod, make relatively rotating between valve rod and the flap, become sliding friction with steel ball by the direct friction between the metal, lighter when operating valve lever, flexible, prolonged the working life of stop valve simultaneously, so the utlity model has very high social value and market popularization value.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing is the utility model embodiment's a structural representation.
Embodiment
The 1-valve rod, 2-flap, 3-annular groove, 4-groove ring, 5-steel ball, 6-through hole, 7-plug, 8-cylindrical cavity
Embodiment, as shown in the figure, a kind of valve rod of stop valve and flap connection set, comprise valve rod 1 and flap 2, flap 2 has the cylindrical cavity 8 that is used for holding valve rod 1 end, the inwall of cylindrical cavity 8 is provided with semicircular rings connected in star 3, valve rod 1 is provided with semi-circular recesses ring 4 with corresponding part, annular groove 3 position, be provided with steel ball 5 in the annular groove 3 of flap 2 and the groove ring 4 formed toroidal cavities of valve rod 1, flap 2 is provided with the through hole 6 that communicates with annular groove 3, described through hole 6 runs through flap 2, have in the described through hole 6 and be used for the plug 7 of shutoff through hole 6, during use, valve rod 1 is inserted in the cylindrical cavity 8 of flap 2, then the annular groove 3 of flap 2 and the groove ring 4 formed toroidal cavities of valve rod 1 are put into and entered to several steel balls 5 from through hole 6 successively, carry out shutoff with plug 7 then and get final product.
