Description

PIPE CONTROLLER TO LINEAR AND LOGARITHMIC FLOW OF LIQUID MEDIA

The subject of the invention is a ball valve insert integrated into a ball valve ball which allows for linear and logarithmic flow of the fluid medium due to its different position and direction of rotation.

A technical problem solved by the invention is a ball valve insert that enables linear and logarithmic flow of liquid medium through the ball valve. The ball valve insert is inserted as an additional part into the existing ball valve ball. The ball valve insert has a longitudinal flow hole of the fluid medium, which is of special shape to the inlet of the liquid medium, which radiates along its length to the circular outlet hole of the liquid medium. The cartridge is inserted into the ball valve ball in such a way that, depending on its position and direction of rotation, the linear and logarithmic flow of the fluid through the ball valve is linear. Rotate the ball valve in which the ball valve insert is inserted in the right and left directions by a maximum of 90 degrees by means of a shaft which transmits torque from the manual rotation or from the controlled drive to the ball valve ball. The cartridge is inserted into a ball valve, which allows the flow of the fluid medium to be steadily or continuously adjusted. The linear flow of liquid medium is achieved by inserting the ball valve by turning the ball of the ball valve in which it is inserted in the right direction for a maximum of 90 degrees, so that the flow of liquid medium through the cartridge is first opened to a wider part especially on the insert of the inlet hole of liquid medium. The logarithmic flow of the fluid is achieved by inserting the ball valve by turning the ball of the ball valve into which it is inserted in the left direction for a maximum of 90 degrees, so that the flow of liquid medium through the cartridge is opened first by a narrower part specially formed on the cartridge hole of the liquid medium. The desired transition from the linear flow of liquid medium to the logarithmic flow of liquid medium through the ball tap and vice versa does not require the installation or disassembly of additional parts of the ball valve. The essence of the invention of the ball valve insert is therefore in the special shape of the inlet hole of the fluid medium, in the form of sections along its length to the circular outlet hole of the fluid medium, in the direction of rotation of the cartridge, at the beginning of the flow of flow of the liquid medium. liquid medium in case of linear fluid flow adjustment, and at the beginning of flow of liquid medium flow through a cartridge at the narrower part of a specially formed liquid medium inlet hole in case of adjusting the logarithmic flow of liquid medium. The overall geometry of the cartridge hole is defined by the geometric parameters of the cartridge as diameters d, D1, D2, radii R, R1, R2, R3, R4, R5, lengths L1, L2, L3, L4 and 60 degrees. The logarithmic and linear flow of the liquid medium through the cartridge is thus achieved by certain mutual relations between the values of said geometric parameters of the cartridge, by the direction of rotation of the cartridge and by the initial position of opening the flow of the liquid medium through the wider or narrower part of the specially formed inlet hole of the liquid medium. The ball valve insert of the invention has great advantages over the existing structural designs of ball valves, since it solves the problem of linear and logarithmic flow of liquid medium through the ball valve in a very successful and very simple way. The ball valve insert also solves the problem of turbulence and associated vibrations, and thus the noisiness of the flow of liquid medium through the ball valve, because it is inside the ball ball and is not in it and between it and the dead ball angle housing. The problem of eddy currents and turbulence of liquid medium flow and the resulting increased noise are caused by ball valves precisely because of dead angles in the ball and in the sphere of the ball and the housing of the ball valves.

The ball valve ball is sealed with two lateral seals and two elastic rings with ball valve housing and threaded connection. The radial grooves on the insert are fitted with elastic rings, which have the function of compensating for the expansion of the material of the ball valve ball and ball valve insert. Since the insert as the object of the invention is to be located in the ball valve ball in a particular position with the ball ball, this position is provided by a pin located in the blind holes of the cartridge and the holes of the ball ball. Alternatively, the position of the insert in the ball valve ball may also be fixed by screws. Depending on the requirements of the ball valve users, the inserts are of different sizes, which in turn allow different flows of liquid medium through the ball valves, which also enables the typing of ball valve components. The ball valve insert as an object of the present invention also has a wider potential for use with other faucets and valves, with the requirement that the basic movement of this cartridge be met. The specially designed ball valve insert hole is also applicable in other taps and valves where linear and logarithmic flow of the fluid medium is desired. With the ball valve insert and its specially designed liquid medium flow hole, which is the subject of the present invention, a linear and logarithmic flow is achieved in the required rotation and flow opening conditions wherever required, so this invention is in ball valve technology and valve technology of wider significance.

Existing ball valves do not have inserts in the ball valves that allow linear and logarithmic flow of the liquid medium at different positions and different direction of rotation. Rough approximations of the desired flow rates are achieved by existing ball valves with liquid medium flow orifices as, for example, solved by patent publication US2001 / 0030309A1 and by patent publication US006039304A patent No. 6,039,304, or a circular ball shaped ball hole shaped ball or an inlet hole such as a flow orifice. Instead of a direct insert into the ball valve ball, the ball valves have only flow diaphragms with different shapes of liquid medium inlet holes, or the liquid medium inlet holes are already integrated with the ball valve ball. Since the flow orifice is not integrated in the ball valve ball, but only laterally touches the ball valve ball, this allows blind angles to be formed between the aperture and the ball valve ball. In these blind corners, foreign bodies can accumulate from installations that cause damage to the ball valves. A disadvantage of such a design solution is the excessive formation of vortices and turbulence of the fluid medium in the blind corners through the ball valve, because the passage of the liquid medium through the aperture or the cut-out immediately continues through the cylindrical flow hole of the ball ball without the flow of favorable passage, which is provided by the ball insert. the tap of the present invention. Such design solutions do not allow the linear and logarithmic flow of the fluid to be complete, but with their curves of flow of the fluid through the valve, depending on the angle of rotation of the ball valve shaft and thus the angle of rotation of the ball valve, are only some approximations to the flow of liquid medium through the ball tap and are considered as modified flow characteristics of ball valves. The problem of existing design solutions for ball valves where partial apertures or only cut-outs in the form of inlet holes are used to partially achieve the required fluid flow

The liquid medium on ball valve spheres is also in that these design solutions require more built-in components, which impairs the standardization and typing, and the economics of design of such ball valves and valves.
