BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a ball valve,

[0001] The present invention relates to a structure of a ball for a valve having a constant rotational force driving function for regulating a supplied flow rate, and more particularly to a structure of a ball for a valve, in which a plurality of disk plates are stacked in a through- And a mirror plate in which an outlet shape is separately provided around an outlet port through which the fluid is discharged under a differential pressure, so that the flow rate and the flow rate passing through the valve can be controlled .

Such a ball valve is characterized in that the stem support shaft is provided at the upper end position, or is installed as a stem fixed shaft at the upper and lower positions have.

In addition, the stem is fixed to the seat by a torque acting at a predetermined angle and a fluid pressure acting on the stem, thereby enhancing the sealing force in a state of being in close contact with the seat.

As related technologies related to such ball valve characteristics, Korean Patent Publication No. 10-1165366 entitled " Dual Ball Valve for Controlling Flow " and Registration No. 20-041825 " Ball Valve for Flow Rate Control " .

However, as to the structure and function of the ball valve as described above, as the fluid introduced into the valve reaches the peak instantaneous velocity of the fluid instantaneously in accordance with the aggregate flow velocity supply pressure within the maximum receiving area range, , There is a problem that abrasion phenomenon occurs due to friction with the surface of the valve passage hole and that no noise and vibration generated by bubble generation can be solved. will be.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art, and it is an object of the present invention to provide a disk cartridge, which is provided with a circular metal plate in a fluid passage of a ball formed by a circular fluid through- And to provide a valve structure device capable of speed control for a fluid entering under a high pressure state, and for dispersing or canceling a fluid pressure.

The operation characteristics of the ball valve composed of the laminated disk assembly as described above are such that during operation of the valve, the fluid tends to flow out of the fluid pressure state in which the fluid passing amount changes according to the stroke stroke angle for the opening of the fluid under a constant pressure differential Which is acted upon by a disc structure having the same area and number of mini-hole passages, the disc arrangement having a maximum range in relation to the fluid storage capacity above all, even if the fluid volume is exceeded, The valve structure must be provided.

Especially, friction between the internal surface wear phenomenon caused by fluid pressure friction passing through the inside of the valve and the flow rate which is caused by the repetitive action of the high-speed flow due to the high differential pressure as a cause of breaking the periphery of the seat portion constituted by a square or curved shape And the bubble phenomenon occurs when the instantaneous temperature of the cavity portion increases when the fluid volume pressure supplied to the inside of the valve tube is reduced to be less than the vapor pressure volume. And vibration and noise are generated due to such a cause, resulting in many difficulties and problems in controlling the valve operation as a result.

In order to solve the above-described problems, a convex plate formed as a type-specific outlet port is provided at an outer end of a circular through-hole front having a functional structure so that the outflow amount of the ball valve can be controlled, A circular disc plate having a small number of mini-holes in the inner circumferential space passed through the inside of the ball base is inserted and inserted into the front surface of the ball base, The present invention provides a method for constructing a pile of discs, which is used as a means for controlling the fluid movement speed under the injection pressure in accordance with the high differential pressure, and to more easily control the fluid volume expansion to be supplied.

In order to accomplish the above object, the present invention provides a ball valve comprising a ball base having inlet and outlet through-holes horizontally widened, and a fixed damper and insertion pipe formed at the periphery of the ball base through- A mirror plate having a fluid outlet which can be assembled with the insertion tube and having a fastening bolt hole; A disk plate which is perforated with small radial mini holes in a hollow space inside the ball base rear through hole; A fastening ring having an outer circumferential surface formed in a threaded shape on the rear surface of the ball base on which the disc plate and the circumferential ring are laminated, And the mirror plate structures are assembled at respective required positions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 5 are views showing an apparatus for constituting a ball valve according to the present invention.

As described above, the structure of the ball valve according to the embodiment of the present invention includes a through hole 11 in a boring state at the center of a spherical ball base 10, (12) formed in an annular shape at the front end position and an insertion tube (13) separately boring on the outer periphery of the fixed top (12), and a mirror surface A convex plate 20 and a sealing 25 are provided and a female thread 15 is formed at the inner surface of the front end of the through hole 11 in the rear of the ball base 10, And a fastening ring (30) that can be inserted and coupled to the through hole (11) in which the part (15) is formed.

A circular disk 40 is provided inside the space of the rear through-hole 11 of the ball base 10 so as to be capable of automatically controlling the amount of fluid, A spacer ring 42 provided so as to form a required space portion when being laminated and assembled in the hole 11 is provided in the hollow space inside the through hole 11 and a disk made of the circular metal material (40) has a suitable numerical aperture (41) formed by a radial small through-hole in the surface of the plate, wherein the diameter of the through hole of the mini-hole (41) is made to be a uniform micro- And mini-holes (41) manufactured in accordance with specialized fluid particle components can be separately configured and used.

The action of the mirror plate 20 assembled to the ball insertion tube 13 of the ball base 10 will be briefly described with respect to the ball valve constructed as described above.

The ball valve of the conventional ball valve is provided with a through hole through which a flow rate can pass. In addition to the seat portion connected to the stem in the valve body portion in the form of a spherical ball so as to be connected with the outflow pipe, It has been used as an extremely simple control means such as shutting off the fluid flow in accordance with the stroke rotational force movement in the assembled state or controlling the flow amount of the fluid.

However, in the ball valve composed only of the conventional method, the peripheral portion of the fluid discharge port formed on the front surface of the ball base is subject to continuous fluid pressure action, which causes wear and breakage due to the surface collision phenomenon frequently applied. I had to change the bass frequently.

In order to prevent the above-mentioned phenomenon, first, in the mirror-surface plate 20 formed of the detachable exchanger structure, in order to control the flow rate at the center of the mirror-surface plate 20, And a bolt hole 22 that can be fastened together with a fastener hole 14 formed at the center of the fastener 12 is formed around the rim of the circular mirror plate 20 in which the outlet 21 is formed, And is assembled and fastened to the insertion tube 13 by means of bolts 23. [

In the specular surface plate 20 assembled in the above manner, when the inner wall portion around the outlet 21 of the specular plate 20 is damaged due to continuous fluid friction during valve operation, the specular plate 20) can be easily replaced and the operation of the valve can be quickly performed.

The structure and effect of the disk 40 installed in the space of the rear through hole 11 of the ball base 10 will be described in more detail as follows.

A disk (40) plate in which a fluid passage hole is perforated in a radial configuration, characterized in that the disk (40) plate comprises a disk stack (43) made up of several stacked structures which can be suitably acted as a flow rate control means The first disk 40 plate is first inserted in the inner side end face of the fixed base 12 formed at the peripheral edge of the insertion tube 13 of the ball base 10 and the intervening fluidic body A disk 40 plate which can be repeatedly assembled in the same assembling order as described above, and a spacer ring 42 are inserted into the through hole 11, And then the fastening ring 30 on which the threaded portion 31 is formed is inserted into the hole to be assembled.

A plurality of the disk 40 plates constituted by the fluid passage hole mini holes 41 and the disk 40 are integrally assembled with the plate 40, In the disc dummy 43 in which the required space is formed by the interlining rings 42 to be inserted and the fluid-passing mini-holes 41 are provided in the horizontal direction at different angles, (11), and when the fluid is pressurized by the valve operating system and the fluid amount starts to flow in the high-speed entry state, the limited pressure rate adjustment is progressed from the final position to the assembled disk (40) plate And such repeated flow rate control can be achieved by varying the supply activations related to the control system depending on the number of discs being fed into the apparatus However, the flow rate naturally passes through the flow passage while maintaining a proper flow rate. As a most characteristic phenomenon, the vortex phenomenon does not occur and a good environment for extending the valve life can be provided.

On the other hand, the fluid flowing through the generally used through-hole ball valve pipe flows at a maximum speed in a state in which the flow rate is not subjected to resistance by a flow velocity environment that instantaneously passes through the downward flow of the collective pressure in the valve, Such a high-speed flow of the fluid may cause the abrasion of the inner wall of the valve. In addition to the abrasion due to surface friction with the fluid, the valve is seriously hindered by noise and vibration due to bubble generation .

Such anomalous phenomenon is also a result of a failure to build a system capable of effectively controlling the flow pressure which is progressed by the stroke maximum opening stroke during valve operation, It is possible to use the disk dummy 43 which is stacked according to the designated quantity so that the fluid can be rapidly dispersed and outflowed from the initial entry process and that such a fluid amount outflow movement can be performed in a stroke stroke, the fluid amount acts to flow out in a large amount in proportion to the fluid pressure, and this is formed at a calculated interval by the disk dummy 43 having the same area and the same number of mini holes 41 The fluid pressure action is interfered with due to the spatial gap between the gap ring 42 and the disk 40, It is also because it induces changes in the genus.

As mentioned above, the fluid velocity is influenced by the number of flow channel mini-holes 41 formed in the individual disk stack and the number of disks 40 installed in the through hole 11 of the ball base 10, If additional speed control means are required, the cross sectional space structure of each passage is changed, so that the control means can be achieved by such a change, and this can be prevented from being damaged by the flow velocity friction as much as possible The flow rate is divided into a plurality of flow passages in accordance with the low flow non-dispersive force distribution, so that the fluid flow is brought close to the pressure reduction step. Further, A ball valve having an excellent moving performance in a quiet environment is restrained by the laminated disc structure devices. Becomes are.
