Description
Technical field
The utility model relates to a kind of bracing type track ball valve, and more particularly, it relates to the little bracing type track ball valve guiding assemblage of a kind of open and close torque.
Background technique
In commercial production, ball valve is being widely used always, and traditional ball valve is to drive unlatching and the closure that valve core rotation realizes ball valve through valve rod, and this type ball valve sealing performance is general, serious wear, and the working life of ball valve is short.In order to overcome these deficiencies, people have designed the bracing type ball valve, and the spool of this type ball valve has adopted wedge-shaped structure, good seal performance, but the guiding assemblage open and close torque of present bracing type ball valve is bigger, and the stationarity of stem movement is poor.
Chinese patent notification number CN2588147Y, on November 26 2003 day for announcing, the name of model utility is called bracing type guide rail ball valve; Comprise driver, valve rod, spool and valve body, valve rod is provided with the directed guide groove of spiral, with the corresponding valve body tube support of the directed guide groove of spiral on be provided with pilot pin; One end of pilot pin stretches in the directed guide groove of spiral; Spool is made up of wedge-like body and flap, and flap is provided with dovetail groove, and links to each other with the dovetail of wedge-like body through dovetail groove; The top of valve rod is connected with driver, and the bottom is connected with the wedge-like body of spool.The guiding assemblage of ball valve comprises pilot pin and the directed guide groove of spiral, and the directed guide groove of spiral is arranged on the valve rod, and pilot pin is arranged on the valve body tube support, and when valve body opened and closed stem movement, moment of torsion was bigger, and the stationarity of stem movement is poor.
The model utility content
The utility model has overcome in the existing bracing type ball valve opening-closing process that moment of torsion is bigger, and the deficiency of the stationarity difference of stem movement provides a kind of bracing type track ball valve guiding assemblage, and it makes ball valve moment of torsion in the process that opens and closes little, and the stationarity of stem movement is good.
In order to solve the problems of the technologies described above; The utility model adopts following technological scheme: a kind of bracing type track ball valve guiding assemblage; Comprise support, the guide finger of valve rod, hollow, rack side wall is provided with the guide slide of two symmetries, and guide slide comprises hoistway and the spiral slideway that is interconnected; The two ends of guide finger are socketed with roller respectively; Two rollers are movably connected in respectively in two guide slides, and the both ends of the surface of guide finger are fixedly connected limiting gasket, and guide finger is fixedly connected with valve rod and their axis normal.During original state, guide finger is connected in the hoistway, and ball valve is closed.When opening ball valve, the valve rod that moves up follows valve rod to move up with the guide finger that valve rod is fixedly connected; After valve rod moved to spiral slideway, guide finger just followed spiral slideway to rotate together, and the valve rod that is fixedly connected with guide finger also begins to rotate; The rotating band of valve rod is automatically connected in the rotation of the spool on the valve rod; Ball valve is slowly opened, and when guide finger turned to the end of spiral slideway, ball valve was opened fully.The two ends of guide finger are connected in the guide slide through roller, make guide finger more steady when sliding, and reduce moment of torsion.The two ends of guide finger connect roller respectively, and guide finger surface friction drag when sliding is little, and open and close torque is little.The two ends that limiting gasket is connected guide finger prevent the play between roller and the guide finger, increase the stationarity of guide finger when sliding.This bracing type track ball valve guiding assemblage makes ball valve moment of torsion in the process that opens and closes little, and the stationarity of stem movement is good.
As preferably, roller is a needle bearing.Adopt needle bearing as roll sleeve, simplicity of design, and also surface friction drag is little.
As preferably, be socketed with roller housing on the roller.The outer surface of roller housing protection roller prevents rolling wheel wear.
As preferably, the two ends near roller on the guide finger are socketed with the friction pad that the PTFE material manufacture forms respectively.The friction pad friction factor that the PTFE material manufacture forms is little, has reduced the link at friction pad two ends and the surface friction drag between the friction pad, helps moving of guide finger.
As preferably, valve rod is provided with attachment hole, and guide finger is connected in the attachment hole and through bolt and connects.Guide finger is connected through bolt with valve rod, connects simple and reliable.
As preferably, the inward flange of two roller housing opposing end surfaces is provided with the inwardly protruded flange of a circle, and an end and the flange of roller connect.Flange makes things convenient for the location between roller housing and the roller, makes between roller housing and the roller to be difficult for axial float.
Compared with prior art, the beneficial effect of the utility model is: bracing type track ball valve guiding assemblage makes ball valve moment of torsion in the process that opens and closes little, and the stationarity of stem movement is good.
