Definitions

  • FIG. 7 illustrates a water- heater with the currently applied connection.
  • the water-heater components are:
  • Boiler (1) Support base (2), hot water input pipe (4), cold water input (3), Relief valve with integrated non-return valve (7), Internal network pipe (11), water heating resistance (5), Thermostat switch (6), City network (13),Water meter (12)
  • the water enters from the main network (13) through the interposing non- return valve (7), thus fill of boiler (1) is achieved.
  • the relief valve (7) is parallel to the circuit and is kept closed under the effect of a spring set at the desired pressure level and operates when the pressure in the boiler (1) exceeds safe pressure level.
  • the function of the non-return valve is to allow the water inflow from the main pipe to the boiler (1), while preventing the reverse flow from the boiler (1) to the network (13).
  • the problems created by the non-return valve are numerous and sometimes 100% dangerous.
  • the water-heaters manufacturers recommend the mounting of a pressure reducer to lower the network (13) pressure.
  • the reducer has a non-returning action, it does not allow reverse flow to the network (13) and causes the aforementioned problems similar to the non-return valve.
  • non-return valve (7) When the non-return valve (7) does not function and remains open due to the cold water pipe (3) connection method at the lower part of the boiler and somehow the network (13) empties, it does not retain the boiler's fullness (1) and as a result there is leakage of hot or cold water to the network (13) Risk of resistance (5) blow due to being in vacuum. Risk of -water network contamination due to inflow of drifted salts or decay products from the magnesium pole fitted in the solar boilers. For the aversion of this last risk, a non-return valve is normally fitted at the input of new supplies. However, this valve also participates 100% in the aforementioned problems of pressure rise in the interior of the boiler (l).To sum up, nonreturn valves not only do not solve any problem but also create all the aforementioned ones.
  • the new multiple-protection system (17), Figure No 2, and the connection of the cold water input pipe (3) on the upper part of the water-heater, aims at the inflow of cold water and the intake of hot water through the relief valve and the retention of the boiler's fullness at the level of the flow line (14).
  • the aforementioned problems are 100% vanished with the application of the system, the elimination of non-return valves (7), the fitting of a new, multiple-relief valve (17) and the retention of the water level at the flow line (14).
  • Figures (1) and (2) illustrate the connection of two boilers which, in terms of components, are identical to Figure (7).
  • Figure (No 3) illustrates a section of a four- way valve according to the present invention.
  • Figure (No 6) illustrates a section of a three-way valve according to the present invention.
  • Figure (No 4) illustrates a section of an alternative four- way valve to Figure (No 3).
  • Figure (No 5) illustrates a section of an alternative three-way valve to figure (6).
  • Figure (No 7) illustrates an installation of a water-heater and its components according to the contemporary, conventional method.
  • Figure (No 1) illustrates an already installed water-heater where the connection according to the new system is presented.
  • Figure (No 2) illustrates the installation of a new water-heater manufactured and connected according to the new system.
  • the valve in Figure (No 3) consists of the cold water inlet (20), through which water flows into the valve body (21), the upper part of the body bears a facet (38) where the elastic valve (37) is located and communicates with the upper part of the valve (26). This part (26) is outside the water circuit and over the elastic valve (37) and communicates with the atmosphere through an opening (27) when the valve (37) is open.
  • the valve body (21) bears a second facet (28) where the relief valve is fitted with a membrane (29), a spring (30) and an adjusting screw (31). It also bears a spiral (42) onto which the cold water pipe (18) is connected.
  • the valve functions as follows: At normal operation the inflow of cold water is done through the inlet, (20), where the water pressure is directed towards the bottom of the boiler (1) Figure (No 2) through the opening (42) and the coaxial pipe (18).In case of overpressure of the system, the elastic valve (37) remains closed and the relief valve (29) opens at the pressure value set with the screw (31).In case of water supply failure from the main and consequent pressure loss, the valve body (21) empties and a sub-pressure is created through the opening (20) in the lower part of the elastic valve (37). As a result, the elastic valve (37) subsides from the facet (38) and the interior (20) communicates with the environment through this part (26) and the opening (27).
  • Figure (No 6) illustrates an alternative to the valve already described of which fitting requires a tee-connection (15) figure (l).
  • Figure (No 4) illustrates a third alternative described whereby the elastic membrane (40) of the relief valve bears an central opening where the whole system of the four- way valve in figure (No 3) for external communication has been fitted.
  • Figure (N 5) illustrates an alternative to the three-way valve fitted parallel to the circuit with the use of tee device. Like the valve in figure (No 6) it bears a facet (22), where the elastic membrane (23) is located, which has a central opening (24) communicating with the upper part of the valve (25). The area (26) is outside the water circuit and under the elastic membrane. It is of a ring-like form and communicates with the atmosphere through the opening 27.
  • the valve body (21) bears a second facet (28) where the relief valve is fitted with a membrane (29), a spring (30) and an adjusting screw (31).

Abstract

La présente invention concerne un système de sûreté d'un chauffe-eau et d'un système hydraulique selon lequel une conduite d'amenée (11) d'eau froide est placée au-dessus du niveau d'écoulement d'eau du chauffe-eau (14), où une soupape de sûreté multiple (17) est fixée, laquelle sert à introduire de l'air atmosphérique dans le cas où la pression dans le réseau chute en dessous du niveau de la pression atmosphérique, ce qui permet de maintenir le niveau d'eau du chauffe-eau à un niveau maximum tout en permettant d'évacuer la surpression dans le chauffe-eau lorsqu'elle dépasse certaines limites. L'alimentation en eau est orientée vers la partie inférieure du chauffe-eau et s'effectue à l'aide d'une connexion à une seule conduite. La soupape de sûreté multiple est fixée à un endroit sur le réseau d'amenée d'eau et placée au-dessus du niveau d'eau supérieur dans le chauffe-eau (14). Un robinet à membrane (29) s'ouvre lorsque la pression dépasse les niveaux de sécurité de pression et décompresse le système. Un robinet d'amenée d'air (37) s'ouvre lorsqu'on observe une baisse de pression dans le réseau, ce qui permet d'éviter que le chauffe-eau ne se décharge. Cette invention permet ainsi de garantir une protection totale contre les risques de surpression dans le chauffe-eau générée par les effets de vases communiquants et empêche le chauffe-eau de se décharger, ce qui pourrait avoir des conséquences incontrôlables et désastreuses. L'orifice d'admission et l'orifice d'évacuation d'eau ne comportent ni soupape ni ressort, ce qui élimine tout risque de formation de sel et toute obstruction pendant leur fonctionnement.
