Abstract
The utility model relates to a rolling orbit sphere valve, which comprises a valve body, a valve base, a sphere body, a valve rod, a valve cover and a hand wheel, wherein the valve base is arranged on an outlet channel of the valve base; outlet side sealing is adopted by the sphere body; a guiding slot which is in movable fit with a guiding pin on the valve cover is arranged at the middle part of the valve rod; inclined surfaces are formed at the lower part of the valve rod; the inclined surface inclines towards the inlet side of the valve body from top to bottom when the valve is in a closed state; the guiding pin is mainly movably arranged in a valve cover installation hole through a screw plug; rolling shafts are arranged at both sides of a connecting hole between the sphere body and the valve rod respectively; the rolling shafts are connected with the inclined surfaces on both sides of the lower part of the valve rod in a contacting and matching way respectively. According to the rolling orbit sphere valve, friction between the valve rod guiding slot and the valve cover guiding pin as well as between the lower inclined surfaces of the valve rod and the sphere body is reduced, the mutual wear is lowered, and the accuracy and stability of control over the movement orbit of the sphere body in opening and closing processes are enhanced; and the rolling orbit sphere valve has the advantages of stable sealing performance, reliability and the like, and is suitable for control valves under high-temperature and high-pressure medium working conditions.
Description
Technical field
The utility model relates to valve field, specifically about a kind of track ball valve.
Background technique
The structure of track ball valve comprises valve body, valve seat, spheroid, valve rod, valve gap, handwheel; Valve seat is installed on the valve outlet passage, and spheroid adopts the outlet side sealing, and spheroid and valve outlet side have space length; Valve rod middle part is shaped on guiding groove and cooperates with guide finger on the valve gap; The L shaped structure that this guiding groove is made up of vertical slot and translot, vertical slot are on the valve rod axis direction, and translot is 90 ° of radians on the valve rod circumferencial direction; Stem lower portion is shaped on the inclined-plane on the plane perpendicular to the valve channel axis, this inclined-plane tilts to the valve body suction side from top to bottom.Behind valve closing, the guide finger on the valve gap is positioned at the top of vertical slot, and during valve opening, valve rod promotes earlier under the guide finger effect, drives spheroid and breaks away from behind the sealing surface half-twist again, has eliminated the friction and wear of ball seal face and sealing surface of seat.Its major defect is: guide finger is fixedly mounted on the valve gap; In opening-closing process, be prone to produce wearing and tearing between guide finger and the guiding groove; Stationary axle on stem lower portion inclined-plane and the spheroid is connected, and also has wearing and tearing between the two, can lose the control requirement to the spheroid movement locus after long-term the use; Make spheroid and sealing surface of seat produce wearing and tearing, reduce sealability.
Summary of the invention
The purpose of the utility model is the shortcoming that exists to existing technology, provides a kind of opening-closing process sealing surface not have friction, the reliable rolling type track of sealability ball valve.
The technological scheme of the utility model comprises valve body, valve seat, spheroid, valve rod, valve gap, handwheel, and valve seat is installed on the valve outlet passage, and spheroid adopts the outlet side sealing; Has space length between spheroid and the valve body suction side valve pocket inwall; Valve rod middle part be shaped on guiding groove and the valve gap guide finger movingly, the L shaped structure that this guiding groove is made up of vertical slot and translot, vertical slot is on the valve rod axis direction; Translot is 90 ° of radians on the valve rod circumferencial direction; Stem lower portion is shaped on the inclined-plane, and this inclined-plane tilts to the valve body suction side at the valve closing state from top to bottom, mainly is that guide finger is movably arranged in the valve gap mounting hole by plug screw; The attachment hole both sides of spheroid and valve rod are respectively equipped with roller bearing, and two roller bearings are connected with the inclined-plane contact matching of stem lower portion both sides respectively.
The utility model has the advantages that all to adopt to roll between guide finger and stem lower portion inclined-plane and the spheroid on stem guiding groove and the valve gap and be connected; Reduced the friction between stem guiding groove and valve gap guide finger, stem lower portion inclined-plane and the spheroid; Reduce wearing and tearing each other; Improve validity and the stability in the opening-closing process spheroid movement locus controlled, have characteristics such as sealability is stable, reliable.
