Definitions
- the present invention is directed to a membrane valve design for flow control and pressure relief which has a shape that follows the anatomy and physiological mechanism of action of a sphincter so that it has no restriction points on the fluid flow.
- Valves are devices by which hydraulic (or gaseous) systems are controlled, generally serving to direct flow, assign blockages, control flow or pressure intensity. Valves can be classified as to how they are operated or as to their function. As for function, the valves can be classified as flow control valve, steering control valve or pressure control valve.
- Flow control valves which are of various types, work by regulating the flow of a pumping. Speed is known to be a function of flow and the section through which flow occurs. In this way, the flow control can be made by modifying the section through which the fluid passes through a flow control valve.
- Uncompensated flow control valves which are the simplest valves that control flow through a choke or restriction.
- the amount of flow that passes through an orifice and the pressure drop in it are directly related so that if the pressure increases, the flow in the valve increases;
- Compensated flow control valves They keep the flow rate value closely constant regardless of pressure variations in the circuit and, like unbalanced units, contain a flow adjustment orifice (or choke).
- the control can be automatic or manual, whether remote or local.
- the control valve opens and closes the internal passage of the fluid in accordance with a control signal.
- the control signal comes from a controller, there is automatic valve control.
- the control signal is manually generated by the process operator via a manual control station, remote manual control is provided.
- the control can be done continuously or on-off. In continuous or analog mode, the valve can stably assume infinite positions between fully closed and fully open. In digital or "on" mode, the valve is only in two discrete positions: either fully closed or fully open.
- Such control can be accomplished through hand switches, pressure controlled switches (pressure switch), temperature (thermostat), level, flow rate or simpler controllers.
- the control signal that reaches the valve actuator can be pneumatic or electronic.
- the pneumatic actuator control valve is the final control element of the absolute majority of flow meshes. Even with the increasingly intensive and extensive use of electronic instrumentation, the pneumatic actuated valve is still the most applied, simpler, reliable, economical and efficient end element than the electronic actuated valve (Ribeiro, 1999).
- the pressure control valve is a device that has the function of relieving the excess pressure of a system, be it pipes that carry or store a liquid or gas under high pressures.
- the purpose of installing a safety valve is to protect the system from the effects of excessive pressure where there is a risk of system damage, explosion hazard and life threatening. This protection occurs when the valve is able to discharge a certain flow rate sufficient to reduce the pressure of a system to a certain safety level.
- CPB cardiopulmonary bypass
- blood is pumped at flows greater than 5 liters per minute. These flows generate high pressures and can exceed 300 immHg, which creates risks of damage to devices such as hemoconcentrators and hemofilters.
- the hemoconcentrator is a device used in CPB to remove liquids from the blood, being formed by a bundle of microporous hollow fibers with microscopic thickness walls. For example, polysulfone fiber is 30 ⁇ thick and has low pressure tolerance. Once the pressure tolerance limit is exceeded, the fiber can rupture and leak blood flowing inside.
- the membrane valve for flow control and pressure relief according to the present invention has an internal sphincter-like shape, notably the pyloric valve, which is one of the most important sphincters of the digestive tract.
- Sphincter is a component of animal anatomy formed by muscular structures of ring-shaped concentric circular fibers that serves to control the degree of amplitude and the flow in or out of a particular hole in a vessel segment, canal or pipe.
- Precapillary sphincters work by regulating the flow in the capillary network according to the need of the tissue irrigated by the capillary network.
- the flow control and pressure relief membrane valve (1) object of the present invention comprises a generally circular shaped body (2) provided larger diameter end sections (3, 4) which are provided with ends (5, 6) for connection in use facilities such as hydraulic or blood circuits and other devices.
- said valve (1) internally comprises a pleated membrane (7), i.e. provided with internal pleats (7a, 7b, 7c, etc.), which is generally made of flexible material.
- the flow control and pressure relief membrane valve according to the present invention comprises at least three pleats or internal pleats (7a, 7b, 7c), but may have, depending on the design for specific use, more than three pleats. .
- said pleated membrane (7) is mounted within the valve body (1) so as to form two distinct compartments, a compartment (8) internal to said pleated membrane (3), as if it were a flow line segment, and another compartment (9) forming an outer space between said membrane (7) and the inner wall of the body (2), composing a type of air chamber. It should be noted that said membrane (7) is attached and fixed to the ends (3, 4) hermetically to avoid any communication between the compartments (8, 9) internal to the body (2).
- FIG. 2 illustrates the valve (1) according to the present invention, in variant containing an external connector or control port (10) for actuation. directly into said housing (9) which axially surrounds the housing (8) of the membrane (7).
- Said compartment (9) comprises within it a known volume of gas or liquid which is introduced or removed by means of an actuating element (not shown) installed in said control port (10) to allow pneumatic or hydraulic control of valve opening or closing (1), either directly or remotely.
- the arrows illustrate the flow of fluid of interest to be controlled, as well as the acting on the contents of the compartment (9) illustrated.
- the membrane valve (1) for flow control and pressure relief of the present invention is anatomically shaped, mimicking the anatomy and mechanism of action of a precapillary sphincter, allowing it to act with the same function without producing greater aggression than the degree of aggression imposed by the precapillary sphincter. Therefore, if produced in biocompatible material, it can be used in a blood circuit.
- the membrane valve (1) for flow control and pressure relief object of the present invention has no flow restriction points.
- the membrane 7 is made of flexible material, it allows adjustments in its shape if any particle or solid material passes through it. This possibility can be glimpsed by the illustration of Figure 3 which shows, in succession, membrane opening configuration (7) from a fully closed position (a) to a fully open position (f).
- FIG. 3 (f) Another feature of the flow control and pressure relief membrane valve object of the present invention occurs when fully opened, as illustrated in Figure 3 (f).
- the membrane valve (1) behaves like a pipe segment with the same diameter as the inlet connector (5, 6), allowing free flow through it.
- the valve according to the present invention can be used for flow control of gases and liquids in general, including viscous, pasty, particulate matter and especially for blood flow control since The valve meets the demands imposed by the blood tissue.
- the membrane valve (1) object of the present invention when mounted in circuit parallel to a main circuit, has the possibility of control by the outlet pressure.
- the valve behaves as a two-way anti-reflux valve. That is, the valve opens in both directions if there is positive pressure (P +) on one side (5, 6) and closes if negative pressure (P-) is applied on one side (5, 6).
- P + positive pressure
- P- negative pressure
- Figures 4 and 5 It is observed that the valve can differentiate between negative pressure (P-) and positive pressure (P +). Still, In this condition, the valve will not operate at pressure gradient, but at absolute pressure.
- the inlet connector (6) is connected to the control port or connector (10), when positive pressure (P +) is applied to the valve inlet (6), it will it closes and when negative pressure (P-) is applied to the valve inlet (6) it opens allowing flow to flow as indicated by the arrows.
- P + positive pressure
- P- negative pressure
- the valve opening pressure is set. In this condition, if a pressure P2> P1 is applied to the valve inlet (6), it will open. If P2 ⁇ P1, the valve will remain closed.
- the membrane valve (1) for flow control and pressure relief object of the present invention can be used as an adjustable relief valve because whenever the pressure at its inlet exceeds the pressure applied at the control port (10). ), the valve will open, relieving the pressure. This feature allows you to choose it as an adjustable relief valve as shown in Figure 7.
- valve By applying positive (P +) or negative (P-) pressure to the control port (10), the valve can be closed or opened to interrupt or control the flow through the valve. This control can even be done remotely, through air or fluid, or through a actuator directly coupled to the valve (1), as illustrated in Figure 8. This possibility configures the flow control valve function.
- valve of the present invention also behaves as a variable resistor, which decreases with increasing pressure because at low pressure in the flow line the valve is substantially closed. When the line pressure increases, it opens proportionally to the pressure, allowing greater flow to pass through.
- valve operation is governed by the perfect gas equation:
- V1 initial volume inside the tube at atmospheric pressure
- V2 final volume after air compression
- V1 2.42 ml (closed valve)
- V2 1.57 ml (valve fully open)
- valve Therefore, for the valve to fully open, a pressure of about 41 1 mmHg must be applied to its inlet. In this condition the valve is configured as a flow limiter. [029] Furthermore, in tests carried out with an exemplary model of the flow control and pressure relief membrane valve object of the present invention, it was found that the flow through the valve is directly proportional to the volume of compressed air in the housing (9). ) and therefore directly proportional to the pressure inside it.
- the flow control and pressure relief membrane valve object of the present invention may also be employed as a pressure isolator, which is commonly used to measure pressures using pressure gauges in hydraulic circuits without the pressure gauge entering. in contact with the liquid contained in the circuit.
- the pressure isolator transmits pressure variations from the circuit to the pressure gauge, but isolates the pressure gauge from direct contact with the circuit.
- the valve (1) according to the present invention must have an opening such that the cross-sectional area is at least equal to the cross-sectional area of the pipe to which the valve is connected so as not to create line resistance. .
- the internal volume of air moved by the membrane should be sufficient to cause full deflection of the pressure gauge reading system.
- the pleated membrane (7) when used with mercury pressure gauges, the pleated membrane (7) must be capable of moving an air volume at least equal to the volume of mercury contained on the meter scale.
- mercury manometer would require a volume of 20 ml of air between the closed position shown in Figure 3 (a) and the fully open position shown in Figure 3 (f).
- valve Due to the already described characteristics of the valve, it can be applied in blood circuits, notably the CPB circuits.
- One of the advantages of this same application is related to the fact that Current pressure isolators are installed in a side path, usually in a "Luer-Lock" outlet connector where there is no flow and thus exposing you to the risk of blood clotting inside the chamber or inside the tube. With the valve according to the present invention there will be no risk of blood clotting as blood flow will pass through the valve which as described above has a physiological shape.
- the flow control and pressure relief membrane valve object of the present invention may further operate as a ratio controlling valve. With the valve control port (10) closed, it will actuate to compensate for variations in resistance of a device installed in a parallel branch, as illustrated in Figure 10. In this design of use it is possible to maintain almost constant the proportion flow at both extensions (R1, R2), regardless of variations in resistance, flow, and pressure in the in-line device. Since the inlet and outlet of both extensions (R1, R2) are connected, the inlet and outlet pressure are equal. Thus, when the resistance of the device in parallel line R1 decreases, the total flow increases and the outlet pressure will be higher due to the increased flow. With this, the valve will open, reducing also the resistance at its branch R2, keeping the proportion constant. If the resistance of the device at extension R1 in parallel increases, the total flow decreases. With this, the pressure at the outlet decreases and the valve closes, increasing the resistance at its branch R2 and, consequently, keeping the ratio constant.
- the valve according to the present invention can actuate in stabilizing the pressure level in the line.
- the control port (10) must be connected to the valve input line.
- the valve remains closed.
- the valve opens allowing the air.
- the air flow in the negative pressure line is within the given limit.
- the valve object of the present invention may also be used as a self-sealing cap (1) for vials (12) as illustrated in Figure 12.
- the valve is closed, preventing its contents from contacting the air.
- the valve (1) opens, releasing its contents.
- This can be very useful in storing liquids that oxidize on contact with air or those that evaporate when not properly confined, such as milk, olive oil, fruit juices, alcohol, ether, etc.
- Another advantage of this use is that to fill the bottle (12) it is not necessary to remove the cap, ie the valve (1). Simply inject the liquid through the valve (1), and once the liquid injection is complete, the valve (1) will close automatically.
- the vial is flexible or has the shape of a pouch, for example, and if the container is filled from a state in which the pouch is initially empty and airless inside at the end of filling. the bag will still be breathless inside. Therefore, there is no need to vacuum pack the product to avoid its contact with air.
- valve of the present invention if mounted on a siphon system (13), as illustrated in Figure 13, produces a very interesting effect.
- the water column (L) after the valve (1) generates a negative pressure that keeps it closed if there is no pressure at its inlet (Y). This avoids the passage of air to the outlet (S) and the passage of odors to its inlet (Y).
- valve (1) prevents liquid inlet (Y) from draining below this level. Thus operating, there will always be liquid (L) inside the siphoned tube, which ensures that no odors will pass to the valve inlet (Y).
- This system can be used in residential sink and sink siphons, or in water vents to prevent air from entering the pipe after it has been emptied or when the system is closed for maintenance.
