Abstract
The utility model discloses a ball valve adjustable in a valve core position. The ball valve comprises a valve body, a valve core and a valve rod, wherein the valve core is arranged in the valve body, and the valve rod is connected with the top end of the valve core. The ball valve is characterized in that a positioning hole is formed in the bottom end of the valve core, the lower portion of the valve body is provided with a positioning shaft corresponding to the positioning hole and capable of being adjusted vertically, and the positioning shaft is arranged in the positioning hole. The ball valve can eliminate positional deviation of the valve core through the positioning shaft when the positioning shaft of the valve body is abraded to cause the positional deviation and enable the valve core to be always tightly matched with the valve body.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of ball valve.
Background technique
Ball valve is made up of valve body and the spool be located in valve body, and spool rotates and realizes the switching of ball valve under the drive of the valve rod of its one end in valve body.And in the process of valve core rotation, spool and valve body or and lining fluorine between the two between can produce friction, particularly the friction between spool bottom and valve body can make the position of spool in valve body offset downward, thereby cause the sealing between spool and valve body to go wrong, have the possibility of leakage.
Summary of the invention
For the deficiencies in the prior art, problem to be solved in the utility model be to provide a kind of can be to spool the position in valve body regulate to eliminate the ball valve of the position skew that frictional loss brings.
For this reason, the utility model is realized in the following way: the ball valve that a kind of valve element position is adjustable, comprise valve body, spool and valve rod, described spool is located in valve body, described valve rod is connected to spool top, it is characterized in that: described spool bottom is provided with positioning hole, described valve body lower portion is provided with corresponding with positioning hole positioning shaft that can up-down adjustment, and described positioning shaft is placed in positioning hole.
Described positioning shaft is screwed onto valve body lower portion, and described valve body bottom is provided with cross section and is T-shaped annular groove, and described annular groove is provided with nut in bottom, described positioning shaft is provided with groove, in described groove, be equipped with locking lever, described locking lever two ends are provided with bolt, and described bolt stretches in annular groove and is spirally connected with nut.
In the utility model, positioning shaft that can up-down adjustment is placed in positioning hole and spool is held is remained in valve body, while making the position of spool occur declining because of frictional loss between spool and positioning shaft, just can eliminate the positional deviation of spool by regulating positioning shaft to push spool, ensure sealing and the serviceability of ball valve.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model takes off the structural representation after positioning shaft and locking lever;
Fig. 3 is the enlarged diagram at M place in Fig. 1;
Fig. 4 is the structural representation of positioning shaft in the utility model.
Embodiment
With reference to accompanying drawing, the ball valve that this valve element position is adjustable, comprise valve body 2, spool 3 and valve rod 1, described spool 3 is located in valve body 2, described valve rod 1 is connected to spool 3 tops, described spool 3 bottoms are provided with positioning hole 9, described valve body 2 bottoms are provided with corresponding with positioning hole 9 positioning shaft 8 that can up-down adjustment, described positioning shaft 8 is placed in positioning hole 9, the up-down adjustment function of described positioning shaft 8 realizes by following structure: described positioning shaft 8 is screwed onto valve body 2 bottoms, described valve body 2 bottoms are provided with cross section and are T-shaped annular groove 10, described annular groove is provided with nut 4 in 10 bottoms, described positioning shaft 8 is provided with groove 7, in described groove 7, be equipped with locking lever 6, described locking lever 6 two ends are provided with bolt 5, described bolt 5 stretches in annular groove 10 and is spirally connected with nut 4, the bottom of described annular groove 10 is a bit larger tham nut 4 can be moved nut 4 and can not drop out annular groove 10 in annular groove 10 bottoms.Positioning shaft 8 in valve rod 1 and the bottom positioning hole 9 on spool 3 tops plays the effect of two point locations to spool 3, make spool 3 in the time rotating, there will not be beat, thereby ensure the stability that spool 3 rotates, reduce the frictional loss between spool 3 and valve body 2, improve the serviceability of ball valve, but between spool 3 bottoms and positioning shaft 8, inevitably there will be wearing and tearing and spool 3 is sunk slightly, now just can adjust the position of spool 3 by positioning shaft 8, first the bolt 5 at locking lever 6 two ends is outwarded winding slightly, make the part of nut 4 and bolt 5 can be in the interior movement of annular groove 10, thereby positioning shaft 8 can be rotated, rotating position axle 8 just can push spool 3 its position is raised slightly, thereby eliminate the positional deviation of spool 3, the position of spool 3 can be closely cooperated with valve body 2 all the time, after putting in place, adjusting just tights a bolt 5, make locking lever 6 locking relative to valve body 2 by the effect of nut 4, can limit the rotation of positioning shaft 8, ensure the accuracy of its location.
