The valve seat adjusting means of the axial location in road.
By adopting technique scheme, valve seat adjusting means made valve seat in advance away from spheroid, phase before spheroid dismounting
The valve seat that cannot shift between relatively, greatly reduces the abrasion of spheroid and valve seat, and next, when can be to it after valve base sealing surface wear
It is finely adjusted, so that sealing property is recovered or use temporarily.Due to spheroid processing produce error, valve seat pass through position from
And strengthen sealing property, it is to avoid spheroid re-work brought inconvenience.The changeless seating position compared, with spheroid
The valve seat of adjusting position, reduces active force unnecessary between the two, that is, reduce switching torque.
This utility model is further arranged to：Described valve seat adjusting means includes transpose chamber and adjustment block, described tune
Position chamber is arranged at valve body along runner circumferentially around runner, and described adjustment block is fixedly installed on valve seat and sliding is in positioning chamber, institute
Positioning chamber is axially divided into the first chamber and the second chamber along runner by the adjustment block stated, and the first described chamber is provided with linking extension tube attached
First seam in road, the second described chamber is provided with the second seam of linking external pipe.
By adopting the different external pipe of technique scheme, the first seam and the linking of the second seam, Ke Yicong
The media such as external pipe gas, fluid, are adjusted the position of adjustment block in the first chamber and the second chamber by the different pressures that medium produces,
I.e. regulating valve seat position, can select different media according to field working conditions, have more preferable practicality, it is preferred to use liquid
Body.
This utility model is further arranged to：Arrange successively along the direction away from spheroid in the first described chamber and the second chamber,
The spring mounting groove that the second described intracavity is provided with the back-moving spring that adjustment block resets to the first chamber and installs back-moving spring.
By adopting technique scheme, adjustment block is resetted by back-moving spring one side to spheroid, make spheroid and valve seat it
Between there is preferable sealing property, on the other hand, multiple back-moving springs are butted on adjustment block, make valve seat in adjusting position mobile more
Plus steadily, there is more preferable working stability, secondly, back-moving spring is as buffering, it is to avoid adjustment block is due to moment excessive pressure
Produce with positioning chamber cavity wall and clash into.
This utility model is further arranged to：Position instruction bar is fixedly installed on described adjustment block, described valve body
Have, along runner is axially arranged, the telescopic hole stretching out valve body for position instruction bar, described indicating arm is provided with scale.
By adopting technique scheme, set up indicating arm, for indicating adjustment block position, that is, instruction valve seat is located
Position, valve body end face is as pointer, corresponding from different scales when indicating arm is located at diverse location.
With reference to the accompanying drawings and detailed description this utility model is further described.
Brief description
Fig. 1 is the structural representation of this utility model specific embodiment；
Fig. 2 is the enlarged drawing of A in Fig. 1；
Fig. 3 is the enlarged drawing of B in Fig. 1.
Specific embodiment
As shown in Fig. 1 Fig. 3, the utility model discloses a kind of ball valve with valve seat regulatory function, including valve body 1,
Valve rod 2, spheroid 3 and valve seat 4, are provided with the runner 11 flowing through for fluid in valve body 1, spheroid 3 rotates and is arranged at valve body 1, valve rod
Lower end drives spheroid 3 to rotate, and upper end is used for operating through valve body 1, valve seat 4 be arranged at runner 11 interior and with spheroid 3 face seal
Cooperation, valve seat 4 is arranged at runner 11 along runner 11 axial slip, and valve body 1 is provided with the axial direction of regulating valve seat 4 runner 11 relatively
The valve seat adjusting means of position, valve seat adjusting means made valve seat 4 in advance away from spheroid 3 before spheroid 3 switch, between comparing no
The valve seat 4 of method displacement, greatly reduces spheroid 3 switching torque, secondly, when it being finely adjusted after valve seat 4 sealing surface wear,
So that sealing property is recovered or use temporarily, then, due to spheroid 3 processing produce error, valve seat 4 pass through position thus
Strengthen sealing property, it is to avoid spheroid 3 re-work brought inconvenience.The changeless seating position compared, with spheroid
The valve seat of adjusting position, reduces active force unnecessary between the two, that is, reduce switching torque.
