Abstract
The invention relates to a valve core for an eccentric rotary valve, in particular to a wing-protective type flow adjusting ball core for an eccentric rotary valve. The ball core is provided with a ball surface (2) that plays a sealing role. The flow adjusting ball core is characterized in that the ball surface (2) is also provided with a coronal boss (1); the surface of the coronal boss (1) is arc-shaped; and furthermore, the ball surface (2) is provided with a slot (3) that is used as a flow adjusting window. The test proves that when the eccentric rotary valve with the ball core is used in a black water system in the fields of coal chemical industries and the like, the service life of a product can be prolonged from 2 months to 18 months, the product has a reliable use effect, and the flow adjusting quality of the product is also improved by 5%.
Description
Technical field
The present invention relates to a kind of spool of camflex valve, especially protective wing type camflex valve Flow-rate adjustment ball core.
Background technique
Existing camflex valve ball core is that the major-minor axle drives eccentric spherical crown rotation; the boss of evagination does not have any protection; the high-speed flow area of medium when little aperture washed away the major-minor spindle nose at a high speed; in Coal Chemical Industry Heisui River, the buck field only can use February; cause the high frequency of equipment to shut down, the control characteristic of product does not become rule simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of protective wing type camflex valve Flow-rate adjustment ball core, camflex valve is used reliably and with long-term in fields such as Coal Chemical Industry, crude oil catalysis, cracking, accumulating, Heisui River, bucks, and improve the use degree of regulation of this type of valve.
For achieving the above object, the technical solution used in the present invention is:
A kind of protective wing type camflex valve Flow-rate adjustment ball core, be provided with the sphere that seals on the ball core, its specialization is, also is provided with the crown boss of one deck on described sphere, this crown boss surface is an arc, thereby and has groove as the Flow-rate adjustment window on described sphere.
Wherein crown boss surface is spherical.
Wherein the groove on the sphere is semicircle.
Wherein crown boss exceeds 2-7mm than described sphere.
Through evidence, use the camflex valve of ball core of the present invention to use in Heisui River systems such as coal chemical technology, life of product can be brought up to 18 months from February, and using effect is reliable, and product flow regulation quality page or leaf improves 5%.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the right elevation of Fig. 1;
Accompanying drawing 3 is the structural representation of existing spool in the background technique;
Accompanying drawing 4 is the schematic representation of spool in user mode.
Embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing:
Shown in Fig. 1,2,4, the present invention is a kind of protective wing type camflex valve Flow-rate adjustment ball core, is provided with the sphere 2 that seals on the ball core, also is provided with the crown boss 1 of one deck on sphere 2, this boss surface is an arc, thereby and has groove 3 as the Flow-rate adjustment window on described sphere 2.
Shown in Fig. 1,2,4, wherein boss surface is spherical, and the groove 3 on the sphere 2 is semicircle.
Ball core of the present invention is a kind of two spheres 2 semiglobes that have the double-eccentric shaft hole, wherein sphere 2 not only works the effect of dredging of regulating in fluid control, play the flap effect simultaneously, than sphere 2 bigger crown boss 1 the axis hole boss that transmission ball core rotates is coated on spheroid inside, spheroid can't be washed on axis hole boss and the transmission stationary axle at the medium that the rotation process high speed flows, improve the reliability that driving component connects.Special Flow-rate adjustment window makes Flow-rate adjustment ratio of precision original structure improve 5% simultaneously; bigger crown boss 1 produces flow resistance in valve base sealing outlet closely; make the pressure drop sudden change can not occur in valve base sealing line place, well protected potted line, prolonged the working life of valve.
As shown in Figure 4, during use, the ball core is assembled in the ball-type valve inner of a hollow, by once back shaft and last transmission shaft are fixed on valve inner, driving upward by rotary pneumatic actuator simultaneously, transmission shaft rotates at body cavity, crown boss 1 on sphere 2 goes to valve fluid inlet valve seat position, because of the off-centre of ball core just can compress valve seat, realizes cutting off sealing.
Claims (4)
1. protective wing type camflex valve Flow-rate adjustment ball core, on the ball core, be provided with the sphere (2) that seals, it is characterized in that: on described sphere (2), also be provided with the crown boss of one deck (1), this crown boss (1) surface is an arc, and on described sphere (2), have groove (3) thus as the Flow-rate adjustment window.
2. protective wing type camflex valve Flow-rate adjustment ball core as claimed in claim 1 is characterized in that: wherein crown boss (1) surface is for spherical.
3. protective wing type camflex valve Flow-rate adjustment ball core as claimed in claim 1 is characterized in that: wherein the groove (3) on the sphere (2) is for semicircle.
4. as any described protective wing type camflex valve Flow-rate adjustment ball core in the claim 1 to 3, it is characterized in that: wherein crown boss (1) exceeds 2-7mm than described sphere (2).
