Abstract
The utility model discloses a novel little moment of torsion ball valve, including valve body, valve rod, spheroid, valve gap, filler, seat kits, seat kits includes left and right seat kits, and left and right seat kits is connected with left and right rack respectively, and left and right rack and same gear engagement, left and right rack lie in the last lower extreme of gear respectively, and the gear drives left and right rack and does the displacement, and the gear is connected with the spanner. The utility model discloses it is rational in infrastructure, open and close moment and almost ignore (only being the friction torque between valve rod and bearing, the filler), magnitude of interference adjustment is convenient, and assembly efficiency is high, and external adjustment can be gone on at any time, long -time operation back, sealed pair has wearing and tearing, can adjust at any time.
Description
Technical field
The utility model relates to a kind of ball valve, is a kind of micro-torque ball valve.
Background technique
Traditional ball valve is in switch motion process, and spheroid contacts all the time with the seal ring of valve component, particularly high pressure, bigbore ball valve, opens and closes moment very large, and volume is large, it is high to consume energy.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, opens and closes novel micro-torque ball valve that moment is very little.
Technical solution of the present utility model is:
A kind of novel micro-torque ball valve, comprise valve body, valve rod, spheroid, valve gap, filler, valve component, it is characterized in that: valve component comprises left and right valve component, left and right valve component is connected with left and right tooth bar respectively, left and right tooth bar and same gears meshing, left and right tooth bar lays respectively at the upper and lower end of gear, and displacement done by the left and right tooth bar of gear driven, and gear is connected with spanner.
Valve rod is set with bearing.
Gear one end is connected with spanner by bearing, the other end dress end cap.
Described gear adopts rake tooth.
Described gear adopts sawtooth.
Described gear adopts stepped tooth.
Described gear adopts involute in form.
Described tooth bar adopts rake tooth.
Described tooth bar adopts sawtooth.
Described tooth bar adopts stepped tooth or involute in form.
The utility model is rational in infrastructure, opens and closes moment and almost ignores (being only the friction torque between valve rod and bearing, filler); Magnitude of interference is easy to adjust, and efficiency of assembling is high, and external adjusts, and can carry out at any time; After long-play, sealing pair has wearing and tearing, can adjust at any time.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the A-A view of Fig. 1.
Embodiment
A kind of micro-torque ball valve, comprise valve body 1, valve rod 2, spheroid 3, valve gap 4, filler 5, valve component 6, valve component comprises left and right valve component, left and right valve component is connected with left and right tooth bar 7,8 respectively, left and right tooth bar engages with same gear 9, left and right tooth bar lays respectively at the upper and lower end of gear 9, and displacement done by the left and right tooth bar of gear driven, and gear is connected with spanner 10;
When valve needs to close, stir spanner, rotated by spanner driven gear, drive left and right tooth bar to do displacement further, left and right valve component departs from spherome surface, and drive unit drives spheroid to do 90 ° of rotations, valve closing by valve rod;
When valve needs to open, reversely stir spanner, by the counterrotating of spanner driven gear, drive left and right tooth bar to do displacement further, left and right valve component and spheroid are combined closely, and drive unit does 90 ° of rotations, valve opening by valve rod drive spheroid.
Valve rod is set with bearing.Gear one end is connected with spanner by bearing, the other end dress end cap.Described gear adopts rake tooth, sawtooth, stepped tooth or involute in form.Described tooth bar adopts rake tooth, sawtooth, stepped tooth or involute in form.
