Abstract
The utility model relates to a three-way positioning V-shaped adjusting ball valve. The three-way positioning V-shaped adjusting ball valve comprises a valve body and a V-shaped valve plug arranged in the valve body, wherein a long shaft is connected with one end of the V-shaped valve plug, and a short shaft is connected with the other end of the V-shaped valve plug. The three-way positioning V-shaped adjusting ball valve is characterized in that the long shaft and the short shaft are arranged on the same axis, the short shaft is connected to the bottom of the valve body in a threaded mode, a shaft sleeve and a withdrawal preventing collar are arranged outside the long shaft arranged in the upper portion of the valve body, the shaft sleeve and the withdrawal preventing collar are sleeved with an adjusting bush in a connected mode, and the adjusting bush and the valve body are in threaded connection. According to the design, the three-way positioning V-shaped adjusting ball valve can bear large differential pressure of a pipeline, and has the advantages that the structure is compact, the valve plug cannot easily deform in the high-temperature state, the integral concentricity of the valve plug is high, and the service life is long.
Description
Technical field
The utility model relates to a kind of three-dimensional positioning V-shaped and regulates ball valve.
Background technique
Traditional V-type is regulated ball valve, and because of its intrinsic Position Design, the pipeline pressure reduction that can bear is less, generally can only reach the 16kg left and right, close at condition of high temperature lower valve core and easily be out of shape when stressed, and the whole concentricity of spool is lower, and stressed friction is larger.
Summary of the invention
In order to overcome the above-mentioned deficiency that in prior art, common V-type is regulated ball valve, the utility model provides a kind of three-dimensional positioning V-shaped to regulate ball valve, this three-dimensional positioning V-shaped regulate ball valve compact structure, can bear larger pipeline pressure reduction, not yielding at condition of high temperature lower valve core, the whole concentricity of spool is high, long service life.
The technological scheme that its technical problem that solves the utility model adopts is: comprise the V-shaped valve core in valve body and valve body, one end of V-shaped valve core connects major axis, the other end connects minor axis, it is characterized in that major axis and minor axis are arranged on same axis, minor axis is threaded in bottom valve body, major axis in valve body top arranges axle sleeve and anti-back collar outward, and axle sleeve and anti-back collar are socketed the adjusting lining outward, regulates between lining and valve body to be threaded.
Be provided with the valve seat that is sealed and matched with the V-shaped valve core on valve body, O type circle and valve seat jump ring are set between valve seat and valve body.
The utility model has the following advantages by above-mentioned specific design:
One, the V-type ball valve is being closed nominal pressure when stressed, and ball core three-dimensional locating bias amount is not more than 0.1mm;
Two, improve control valve leakage standard and reached 30 percent;
Three, control valve closes at high temperature ball core that to reach spheroid when stressed indeformable, and increasing the service life reaches one times;
Four, the V-type ball valve bears pipeline pressure reduction and brings up to 25kg pressure reduction from original 16kg pressure reduction, has enlarged using scope;
Five, improve the whole concentricity of spheroid, reduced stressed friction, improved the adjusting resolution of modulating valve.
Description of drawings
Below in conjunction with drawings and Examples explanation detailed content of the present utility model.
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in the figure, the utility model comprises the V-shaped valve core 2 in valve body 1 and valve body 1, one end of V-shaped valve core 2 connects major axis 3, the other end connects minor axis 4, major axis 3 and minor axis 4 are arranged on same axis, minor axis 4 is threaded in valve body 1 bottom, outer axle sleeve 5 and the anti-back collar 10 of arranging of major axis 3 in valve body 1 top, lining 6 is regulated in the outer socket of axle sleeve 5 and anti-back collar 10, regulating lining 6 is threaded with 1 of valve body, be provided with the valve seat 7 that is sealed and matched with V-shaped valve core 2 on valve body 1,1 of valve seat 7 and valve body arrange O type circle 8 and valve seat jump ring 9.Major axis 3 of the present utility model and minor axis 4 turn to be positioned on same axis, minor axis 4 be threaded connection axially locating in valve body 1 bottom, major axis 3 consists of the three-dimensional location by regulating lining 6 axially locating that is threaded on valve body 1 top.In working order, major axis 3 drives V-shaped valve core 2 and rotates, and valve seat 7 is fitted in V-shaped valve core 2 surface maintenance sealing states under the effect of valve seat jump ring 9, and when turning to several angle, valve is in open mode, and reverse operating, valve namely are in closed condition.Above-described embodiment is described the preferred implementation that the utility model three-dimensional positioning V-shaped is regulated ball valve; be not that design and scope to model utility limits; under the prerequisite that does not break away from the utility model scheme; various external form modification and improvement that those skilled in the art make the technical solution of the utility model all should fall into the protection domain that the utility model three-dimensional positioning V-shaped is regulated ball valve.
Claims (2)
