Description

A Pressure Discharge Mechanism for Water Heating Tank Description TECHNICAL FIELD The present invention refers to a pressure discharge mechanism for water heating tank.
BACKGROUND ART Many structures including residential buildings, businesses, industrial plants and so on, are equipped with systems that include a heating tank and are used to heat water or other fluids. Such systems are equipped with a safety valve that releases part of the water in the tank into the surrounding environment in case of over-heating of the water, thus protecting the system against bursting of the tank or of other components of the heating system, such as water pipes.
The safety valve commonly in use today in water heating systems, and particularly in water heating tanks installed in residential buildings, is usually installed adjacent to the heating tank, usually on the cold water inflow pipe.
The valve includes a system that releases some of the water into the surrounding environment in case of over-heating and over-pressure, with the objective of preventing the bursting or explosion of the tank or piping. In the past, most water heaters, and therefore most safety valves as well, were installed on the roofs (tiled or other) of buildings, so that the release of water into the environment on the roof caused no special damage, other than the waste of water. Please note that any single event of water release through the safety valve as a result of over-heating causes a small, but permanent/continuous leak from the safety valve's outlet. Since it is now customary to install water heaters, as well as the adjacent safety valves, in the space between the house's ceiling and the tiled roof or within the house itself, such constant leakage, as well as the water released upon release of pressure create moisture in the house's ceiling and damage to the apartment, the neighbors' apartments and the entire building.
There is a need for a pressure discharge mechanism for water heating tank that can disconnect and reconnect power to the water heating tank in case of over- heating or over-pressure and thus prevent the need to release water outside the tank. The pressure discharge mechanism subject of the present invention also includes an option to release water in case of failure to disconnect the power to the heating tank.
DESCRIPTION OF THE DRAWINGS The intention of the drawings attached to the application is not to limit the scope of the invention and its application. The drawings are intended only to illustrate the invention and they constitute only one of its many possible implementations.
FIGS 1 and 1 depict schematically the pressure discharge mechanism (1).
FIG. 3 depicts schematically the pressure discharge mechanism (1) connected to the main pipe line (200) and to the heating tank (100).
THE INVENTION The main object of the present invention is to provide a pressure discharge mechanism (1) for water heating tank (100) that includes the followings: (a) a first compartment (21) that includes an inner peripheral rim (5) that delimits the first compartment, and a water inlet (2) that is designed to be connected to a water pipe line (200). (b) a second compartment (22) that includes a cavity (222) that is ended with a pressure discharge aperture (16), and a water outlet (3) that is designed to be connected to the water heating tank (100). (c) a third compartment (23) and a snap action switch (14) that is installed on the third compartment. (d) a disk (6) that is positioned on the inner peripheral rim (5), and a spring (7) that is positioned between the disc and an inner wall (221) of the second compartment, in such a way that the spring exerts pressure on the disc and presses it on the inner peripheral rim. (e) a diaphragm (9) that is attached to a peripheral wall (10) of the third compartment and delimits the third compartment. (f) a rigid rod (13) in a position penetrated through the diaphragm, in such a way that its first end (131) is close to the snap action switch, and its second end (132) is in a position penetrated inside the cavity, in such a way that it is designed to prevent water to bursts out through the aperture. (g) a diaphragm spring (15) that is positioned between the diaphragm and an inner wall (231) of the third compartment, in such a way that the diaphragm spring can exert pressure on the diaphragm.
The pressure discharge mechanism is designed in a way that when water is consumed from the heating tank then water can flow through the water inlet into the first compartment and can push up the disc and flow to the second compartment and further through the water outlet to the heating tank.
The pressure discharge mechanism is designed in a way that when water in the heating tank is heated beyond a certain degree the water expands and exerts pressure on the diaphragm that causes the rigid rod to move towards the snap action switch and to press on the snap action switch that is designed to disconnect the power to the heating tank. It is known that water expands when heated and it expands about four percent in volume when heated from room temperature to its boiling point, so that when water is heated, it expands and increased in volume, and by that exerts pressure on the diaphragm.
The pressure discharge mechanism is designed in a way that when the water in the heating tank is heated beyond that certain degree the water expands more in volume and exerts more pressure on the diaphragm and by that causes the rigid rod to move further and to reveal the aperture so that water can bursts out through the aperture and by that to reduce water pressure in the heating tank.
The second version of the pressure discharge mechanism (1) for water heating tank (100) includes the followings: (a) a first compartment (21) that includes a first inner peripheral rim (51) that delimits the first compartment, and the water inlet (2) that is designed to be connected to the water pipe line (200). (b) a second compartment (4) that includes the water outlet (3) that is designed to be connected to the water heating tank (100). (c) a third compartment (23) and a snap action switch (14) that is installed on the third compartment. (d) a first disk (61) that is positioned on the first inner peripheral rim (51), and a first spring (71) that is positioned between the first disc and the inner wall (221) of the second compartment, in such a way that the first spring exerts pressure on the first disc and presses it on the first inner peripheral rim. (e) a diaphragm (9) that is attached to a peripheral wall (10) of the third compartment and delimits the third compartment. (f) a rigid rod (13) that its first end (131) is close to the snap action switch and its second end (132) is attached to the diaphragm. (g) a diaphragm spring (15) that is positioned between the diaphragm and the inner wall (231) of the third compartment, in such a way that the diaphragm spring can exert pressure on the diaphragm. (h) a fourth compartment (24) that includes a second inner peripheral rim (52) that delimits the fourth compartment, and a pressure discharge aperture (16); a second disk (62) that is positioned on the second inner peripheral rim (52), and a second spring (72) that is positioned between the second disc and an inner wall (241) of the fourth compartment, in such a way that the second spring exerts pressure on the second disc and presses it to the second inner peripheral rim; (i) The pressure discharge mechanism is designed in a way that when water is consumed from the heating tank then water can flow through the water inlet into the first compartment and can push up the first disc and flow to the second compartment and further through the water outlet to the heating tank. (j) The pressure discharge mechanism is designed in a way that when water in the heating tank is heated beyond a certain degree the water expands and exerts pressure on the diaphragm and by that causes the rigid rod to move towards the snap action switch and to press on the snap action switch that is designed to disconnect the power to the heating tank. (k) The pressure discharge mechanism is designed in a way that when the water in the heating tank is heated beyond that certain degree the water expands more and exerts pressure on the second disk and pushes up the second disc and flow to the fourth compartment and then bursts outside through the aperture.
The pressure discharge mechanism is designed to disconnect and reconnect power to the heating tank in case of over-heating or pressure that exceeds a pre- set emergency pressure, thus preventing the need to release water into the surrounding environment. The pressure discharge mechanism also includes the option of releasing water into the surrounding environment in case of failure to disconnect power to the heating tank, rendering it a final line of defense.
The pressure discharge mechanism is designed to be installed on the cold water pipe entering the heating tank from the main water pipe (200), but it can be installed also on any one of the pipes connected to the heating tank, such as the hot water outlet to the house's hot water pipe or to one of the water pipes from (or to) the solar collectors (if present) to (or from) the tank.
The disk (6) and the spring (7) serve in fact as a one-way valve that prevent the passage of hot water and high pressure to the cold water pipe, but enabling water to flow from the pipe line to the heating tank. During the normal operation of the heating tank, whenever water flows from the main pipe into the tank, the flowing water pushes the disc upward, enabling the regular flow of water into the tank. The spring (7) force must obviously be relatively weak in order to enable free flow of water into the tank and strong enough to seal the disk to the rim.
When the water in the tank is heated above the certain pre-set temperature causing a certain pressure, which is considered the emergency pressure, the water in the second compartment exerts pressure on the diaphragm and causes it to move towards the snap action switch and causing the snap action switch to disconnect to power to the heating tank. When the water cools and the pressure drops, the rod moved back and causes the power to resume. The diaphragm (9) and the rod (13) are pushed back by the diaphragm spring (15) with a force that corresponds to the pressure pre-set as the emergency pressure of the water heating system.
The pressure discharge mechanism also includes a secondary system designated to release water and pressure into the surrounding environment in case of failure in the power disconnect systems as specified above.
Figures 1 and 1 depict schematically the pressure discharge mechanism (1) and its components. Figure 3 depicts schematically the pressure discharge mechanism (1) connected to the main pipe line (200) and to the tank (100).
