Definitions
- Patent.Invention has as its object a regulating valve for large pressure jumps, which provides a set of notable and important advantages and innovations compared to current va_
- Control or regulation valve used with the same or similar purpose.
- valve 20 of the valve which is not symmetrical and due to the difference in pressure between the inlet and the outlet side, it pushes the closing member (shutter) laterally against its guide (case or cylinder).
- the proposed design solves for the first time the problem of lateral forces, thanks to the existence of two equilibrium chambers. These cameras are 5. annular spaces. surrounding the closing organ, where the pressures equalize around it. In this way, the closing element is not pushed laterally and the reasoning and wear are reduced.
- this design has provided for the establishment 10 * to an intermediate chamber inside the shutter, which is hollow, and whose pressure compensates for the vertical forces that exist on the shutter-, of. so that the set of vertical stresses is null in all the positions of the closing organ, and therefore the effort required for its movement is very small.
- Figure 1 represents a sectional view of the valve of the invention.
- FIG 2 shows a detail of the previous one. 25.
- the parts of the valve are indicated the seat (1) that extends downwards in a perforated part, the cylinder (2) and the shutter (3), which is hollow, and can have two or three decreasing diameters d top down. 30.
- the proposed design is based on the division - of the pressure jump into several minor jumps. To do this, it establishes stages or intermediate chambers between the input and the balance, combining the aforementioned diameters of the seal. "dor with the corresponding ones of the cylinder (2) and seat (1), being able to create for example 1.2 or 3 intermediate pressure steps, as requested by the magnitude of the pressure jump. 5.
- it represents the design of 4 pressure leaps, with three chambers or intermediate steps: a lower annular chamber (4) around the diameter - smaller of the shutter (3), between it and the seat (1), a cylindrical chamber (5 ) inside the shutter itself
- the fluid passes from the high pressure dock below, through a first -
- restriction (1-4) to the chamber (4) where the first step is established. Before entering the chamber (5), the fluid must pass the restriction (4-5) where the second pressure step is taken, approximately the average of the valve inlet and outlet pressures.
- annular chambers (6) and (4) act as equilibrium chambers. This means that the pressure It is equalized around the shutter (3) in all its circumference.
- the shutter (3) is not dragged horizontally in any direction (as in the current 5. designs), but "floats" between both sides, allowing its vertical displacement to be smooth. E difinitive, the shutter - (3) is balanced in a lateral direction.
