Description

Valve for heating circuits.

Object of the invention

The present invention relates to a valve applicable preferentially and mainly in circuits of heating, intended for mounting on a valve body that It can be variable or from a collector.

The object of the invention is to provide a valve through which it is possible to regulate the flow of water or any heat-carrying liquid, as well as measuring exact form the amount of liquid passing, allowing to maintain a correct temperature in the room to which the circuit on which the valve itself is applied bliss

Background of the invention

In air conditioning systems are used different types of valves, all provided for a heat exchange fluid circulates through them, going generally mounted on the emitters themselves (radiators, fancoils, etc).

In this sense, different types of valves and detectors for radiators, which in some cases are provided to regulate the flow of the fluid, and in other cases to measure it, although there is no known valve that performs simultaneously the two functions, that is, measure the flow rate and regulate the amount of fluid, in a single body, since for those two functions two independent elements are used, one as regulator and another as a flow meter.

In this regard, the European Patent can be cited 0936522 referring to a flow regulator based on the displacement of a piston that according to one direction or another of displacement allows to carry out a regulation in greater or smaller measure of the own flow.

Similarly, the European Patent can be cited 0456612, and even the Spanish Utility Models 193679 and 131896, referring to valves for heating radiators, provided as previously stated to regulate the flow of the circulating fluid or water

That is, the common denominator in all existing and applicable valve systems in circuits air conditioning, is that there are no valves that combine the operation corresponding to the flow regulation and the measurement of the fluid that is passing through it, since to be able to regulate and measure the flow of water the Collaboration of an independent valve and flowmeter with their corresponding accessories for connections or others conventional systems to carry out said regulation, all which is a great difficulty, both because of the way installation as per the space they occupy, which results from extreme importance, because due to the little space available installation of this system is virtually unrealizable conventional in many installations.

Description of the invention

The recommended valve has been designed to solve the problem described above, based on a simple but highly effective solution, constituting a valve of balanced for heating since it allows a correct flow regulation and hydraulic balancing of the installation in One item

More specifically, the valve of the invention is materializes from a transparent body fixed with character adjustable and axially on a fixed body that is mounted on the corresponding valve body on which the fluid circulation duct, and whose transparent body It has the particularity of including a scale that allows measuring the flow rate of the liquid that is entering through the body valve due to the displacement of a mounted needle axially inside said transparent body, needle that at its lower and outer end it is finished off in a floating part which is located in the fluid circulation duct belonging to the valvular body, all so that the aforementioned transparent body and by means of an extreme and external steering wheel your position in approach or distance can vary of a valve seat belonging to the valve body, and so on strangle the passage of liquid or water to a greater or lesser extent, with the corresponding displacement in one direction or another of the needle and its indication on the graduated scale of the transparent body.

In this way it is possible to regulate the flow rate of the water or liquid that passes through the valve body, and on the other part it is possible to measure said flow rate by means of the needle movable inside the transparent body.

The fixed body in which the body is threaded transparent, it is the one that is fixedly mounted on the body valve, being fixed by means of an appropriate nut that allows the application of the valve assembly to different types of valvular bodies.

The transparent body at its end of confrontation with the seat of the valve body or manifold presents a stop that sets the maximum opening of the valve, and low said stop a sealing ring for closing the valve when it supports, by descent of the transparent body, on the seat of the valve or manifold body, collaborating with said ring of tightness a stop washer that allows the gasket or ring sealing does not suffer permanent deformation even in the constant closing position for the valve.

Preferred Embodiment of the Invention

As you can see in the referred figures, the valve of the invention is constituted from a body transparent (1) inside whose needle is mounted that is scrollable up and down from that transparent body (1), this one having a graduated scale (3), as shown in figure 1.

That transparent body (1) is mounted on a fixed body (4), assembly that is made by thread, so that the drive through a handwheel (5) set at the end upper transparent body (1) in one direction or another, carries I get the upward and downward displacement of the transparent body (1) with respect to the valve body or manifold (6) on which the valve itself is mounted, so that the fixed body (4) is mounted on said valve body or manifold (6) and fixed by a nut (7) that allows the application of valve assembly to any type of body or manifold (6), settling between it and the fixed body (4) rings of tightness (8) that ensure the tightness between both bodies, while the tightness between the transparent body (1) and the fixed body (4) is achieved by sealing rings sliders (9).

The lower end of the needle (2) emerges from the outer transparent body (1) and is finished off in one part floating (10) that is located in the corresponding duct (11) of measurement of liquid or fluid circulation, the direction being of circulation indicated by the arrow (12) that can be seen in the figure 2.

The lower section of the transparent body (1) incorporates a stop (13) indicator of the maximum opening of the own valve, as well as a washer (14) in combination with a ring tightness (15) provided for this in the closing of the valve rest on the seat (16) of the valve body (6) or manifold, such and as depicted in figure 3.

The sliding needle (2) is opaque to that highlights your view from the outside, needle (2) that moves inside the transparent body (1) depending on the amount of liquid that passes through the measuring line (11) corresponding to the valve body (6) or manifold, and whose liquid in its upward circulation through the duct (11) pushes towards  above the float element (10) the needle (2), displacing this up, which when faced with the scale (3) will provide the measurement of the liquid that is entering or that circulates through the valve body, while the drive in a certain direction of the steering wheel (5) of the transparent body (1), carries with it the downward displacement of the latter until the sealing ring (15) rest on the seat (16), closing the  passage of the liquid, that is, establishing the closure of the valve.

The nut (7), as already stated, allows the adaptation of the valve assembly to its assembly in different valvular bodies (6) and manifolds, making it in this way universal use

For its part, the sealing ring (15) in Combination with the washer (14) is manufactured with a calibration such that it makes a perfect seal against the seat (16) of the manifold or valve body (6), without the gasket or ring (15) undergo permanent deformation, thus avoiding that could get stuck after a long time totally closed.

In short, using the valve described, get on a regular part the flow of liquid or water that passes through the duct (11) of the valve body or manifold (6) and on the other part allows to know exactly the amount of water or liquid that is entering, based on the indication offset of the needle (2) sliding inside the transparent body (1), needle (2) that is visible in its confrontation over the corresponding scale (3) of the transparent body itself (1).

Finally, say that the transparent body (1) It is a single-piece body thus avoiding risks of leakage, being constituted in an appropriate material so that you can work with fluids whose temperatures are between 5 and 95 ° C, ensuring tightness through the aforementioned rings (8 and 9) and in the closure by means of the sealing ring or seal (fifteen).
