The implementation of the invention

In FIG. 1-2 presents an exemplary embodiment of the proposed technical solution.

The proposed kit for connecting a water heater can be used to connect a water heater known from the prior art, preferably a storage type, the kit of which includes safety valves (1). A water heater known from the prior art comprises a tank for heating water, an inlet pipe for introducing cold water (or a "pipe for cold water") and an outlet pipe for discharging hot water (or a "pipe for hot water").

Safety valves (1) are safety valves known from the prior art, designed to protect a water heater from destruction if excessive pressure occurs in it by automatically discharging excess water. In addition, safety valves (1) provide the function of pressure reducing valves to protect the water heater from high inlet pressure and the function of a non-return valve: it prevents water from entering the water system from the water heater when the pressure in it is less than the pressure in the water heater. Safety valves (1) contain a housing that includes an inlet pipe (2), an outlet pipe (3) and a drain pipe (4). In this case, the inlet pipe (2) further comprises an external thread, and the outlet pipe (3) further comprises a union nut (5).

The kit for connecting a water heater (hereinafter referred to as the Kit) includes a drainage unit (6), comprising a housing including a pipe (7) for connecting to the inlet pipe of the water heater (or “first pipe”), an output pipe (8) (or “ the second pipe "), the first inlet pipe (9) for connecting to the outlet pipe of the safety valve (1) (or the" third pipe "), the second inlet pipe (10) for connecting to the drain pipe (4) of the safety valve (1) (or "Fourth pipe"), the locking element (11) and the protrusion (12), the first a pipe (13), a second pipe (14) and a third pipe (15). In this case, the first pipe (13) and the second pipe (14) are designed to connect the drain pipe (4) of the safety valve (1) and the second inlet pipe (10) of the drain unit (6). The outlet pipe (8) further comprises an external thread, and the second inlet pipe (10) further comprises an external thread, and said protrusion (12) is located inside the body of the drain assembly (6) in the connection zone of the second inlet pipe (10) and the outlet pipe (8) ), has a cross-sectional shape and is directed (bent) towards the outlet of the outlet pipe (8), i.e. by the movement of water. The body of the drain assembly (6) and / or the locking element (11) of the drain assembly (6) can be made of material known from the prior art, preferably metal. In addition, the locking element (11) can be any locking element of shutoff valves known in the art and is designed to shut off the water flow from the inlet pipe (7) for connecting with the inlet pipe of the water heater to the outlet pipe (8), i.e. inside the drain unit (6). In this case, the inlet pipe (7) for connecting to the inlet pipe of the water heater further includes an internal thread. The internal thread of the nozzle (7) for connection with the inlet of the water heater can be used to connect to the inlet of the water heater directly or through at least one additional pipe connected at one end to the drainage unit (6), and the other to the inlet of the water heater. The external thread of the first inlet pipe (9) can be used to connect to the outlet pipe (3) of the safety valve (1) directly (preferably) using a union nut (5) or through at least one pipe (if necessary, using a union nut ( 5)).

The drainage unit (6) is configured to operate in two modes: the mode of supplying water to the water heater and the mode of draining water from the water heater. In the water supply mode, the locking element (11) provides a directed flow of water from the first inlet pipe (9) for connecting to the outlet pipe (3) of the safety valve (1) in the pipe (7) for connecting to the inlet pipe of the water heater and prevents water from entering the outlet branch pipe (8). In the mode of draining water from the heater, the locking element (11) provides a directed flow of water from the pipe (7) for connection with the inlet pipe of the water heater to the output pipe (8).

The first pipe (13) has an L-shaped shape and is made with the possibility of connecting one end (16) with the drain pipe (4) of the safety valve (1), the second end (17) with one of the ends (18) of the second pipe (14) containing a U-shaped section, and its second end (19) is made with the possibility of connection with the second inlet pipe (10) of the drain node (6). In this case, the second end (17) of the first pipe (13) contains an external thread, and the second pipe (14) further includes a first union nut (20) made with the possibility of connection with the external thread of the second end (17) of the first pipe (13) , and a second union nut (21), configured to be connected to the external thread of the second inlet pipe (10) of the drain assembly (6). The third pipe (15) is made L-shaped, contains a union nut (22), made with the possibility of connection with the external thread of the outlet pipe (8) of the drain unit (6).

The kit further includes a tank (23) for collecting drainage, which is a reservoir containing an inlet (24) and an air vent (25). The third pipe (15) is designed to connect the drainage unit (6) and the container (23) for collecting drainage: one end (26) of the third pipe (15) is connected to the drainage unit (6), and the second end (27) of the third pipe (15) ) is located inside the inlet (24) of the tank (23) for collecting drainage. In addition, the drainage collection tank (23) is designed to store water and can be made of any material known from the prior art that can withstand high temperatures, preferably plastic (or metal), and can have any given volume and any given shape.

Also, to increase the rate of water discharge, the prior art kit includes a three-way valve (28) known from the prior art, preferably a three-way ball valve. The three-way valve (28) contains a housing including a pipe (29) for connecting to the outlet pipe of the water heater, a pipe (30) for air supply, an output pipe (31) and a locking element (32) with a T-shaped slot. At the same time, the pipe (29) for connection with the outlet pipe of the water heater contains an internal thread used to connect to the outlet pipe of the water heater directly or through at least one pipe. The pipe (30) for supplying air contains an external thread and an outlet pipe (31) used to connect to the pipe of the main pipeline using the thread. The outlet pipe (31) further comprises an external thread.

To prevent accidental flooding due to improperly closed three-way valves (28), the kit additionally contains a check valve known from the prior art, for example a check valve. Said non-return valve may be connected to a pipe (30) for supplying air to three-way valves (28), for example, directly or by means of at least one pipe, wherein said thread can be used.

The three-way valve (28) is made with the possibility of working in three modes: the mode of supplying hot water from the water heater, the mode of supplying air to the water heater and the mode of shutting off hot water. In the hot water supply mode, the locking element (32) provides a directed flow of water from the pipe (29) for connection with the outlet pipe of the water heater to the output pipe (31) and prevents water from entering the pipe (30) for air supply. In the air supply mode, the locking element (32) provides a directed air flow from the pipe (30) to supply air to the pipe (29) for connection with the outlet pipe of the water heater and prevents air from entering the outlet pipe (31). In the hot water shut-off mode, the locking element (32) is moved to a position in which water from the pipe (29) cannot enter either the pipe (30) for air supply or the outlet pipe (31). The three-way valve body (28) and / or the locking element (32) can be made of material known from the prior art, preferably metal. Thus, the three-way valve (28) is configured to supply air to the water heater, shut off the outlet pipe (31) for hot water to disassemble the water heater, and supply hot water to the main pipeline.

Shut-off valves (33) can also be used to connect the water heater. Shut-off valves (33) are designed to block the flow of cold water into the water heater and includes a housing including an inlet pipe (34), an outlet pipe (35) and a locking element (36). In this case, the inlet pipe (34) additionally contains an external thread, and the output pipe (35) further includes an internal thread and is configured to connect to the inlet pipe (2) of the safety valve (1): the internal thread of the outlet pipe (35) of the stop valve (33) is configured to connect to the external thread of the inlet pipe (2) of the safety valve (1). The mentioned external thread of the inlet pipe (34) can be used to connect the shut-off valves (33) with the pipe of the main pipeline. Shutoff valves (33) are configured to operate in two modes: open and closed. The shutoff valves (33) are closed when the locking element (36) blocks the flow of water from the inlet pipe (34) to the outlet pipe (35). The shut-off valve (33) is open when water from the inlet pipe (33) flows freely into the outlet pipe (35).

The kit works and is used as follows.

Closed shut-off valves (33) are connected to safety valves (1). Safety valves (1) are connected to the drain assembly (6). The drainage unit (6) is connected to the water heater and the tank (23) to collect drainage and transferred to the mode of supplying water to the water heater. Three-way valves (28), previously transferred to the hot water shut-off mode, are connected to the water heater.

When connecting devices (for example, plumbing equipment), the joints are sealed by any method known in the art, material (linen, FUM tape, etc.), washers and / or other technical means known from the prior art.

Hot water mode. When the shutoff valves (33) are opened, water flows through it to the safety valves (1), then to the drainage unit (6) and to the water heater.

Three-way valves (33) are transferred to the mode of water supply from the water heater. As a result, hot water from the water heater enters the three-way valve (33), and then into the water supply system to the consumer.

In case of exceeding the maximum permissible pressure inside the water heater, safety valves (1) are activated. In this case, water from the water heater enters the drainage unit (6), then into the safety valve (1), then through the drain pipe (4) of the safety valve (1) into the first pipe (13), into the second pipe (14), into the second the inlet pipe (10) of the drainage unit (6), into the outlet pipe (8) of the drainage unit, into the third pipe (15) and into the container (23) for collecting drainage.

Drain mode. To empty the water heater, the drainage unit (6) is transferred to the water drain mode, and three-way valves (33) are transferred to the air supply mode to the water heater. Water from the water heater through the drainage unit (6) and the third pipe (15) enters the tank (23) to collect drainage. Air through three-way valves (33) enters the water heater, preventing its deformation (crushing of the tank).

In an exemplary embodiment of the invention, a first pipe (13) and a second pipe (14) were used to connect the drain pipe (4) of the safety valve (1) and the second inlet pipe (10) of the drain unit (6). It is obvious that at least one pipe known from the prior art can be used to connect the drain pipe (4) of the safety valve (1) and the second inlet pipe (10) of the drain assembly (6), which, if necessary, can contain at least one pipe the nut.

In an exemplary embodiment of the invention, the drain assembly (6) comprises a protrusion (12). Said protrusion (12) is intended to at least prevent the flow of water into the first pipe (13) and / or the second pipe (14), for example, when draining the water from the water heater, to protect it / them from clogging with debris and deposits from the water heater, and in other embodiments, may not be present.

In an exemplary embodiment of the proposed invention, the tank (23) for collecting drainage contained one air vent (25). Obviously, the tank (23) for collecting drainage may contain at least one air vent (25), which is a means known from the prior art, configured to release air from the tank (23) for collecting drainage, for example, a manual air vent, an automatic air vent etc.

In an exemplary embodiment of the invention, a third pipe (15) was used to connect the drain assembly (6) and the container (23) to drain the drain. Obviously, in other embodiments of the invention, at least one pipe may be used to connect the drain assembly (6) and the container (23) to drain the drain, which may optionally contain at least one union nut.

In an exemplary embodiment, a container (23) was used to drain the drain. Obviously, in other embodiments of the invention, the outlet pipe (8) of the drainage unit can be connected to the sewer through an air gap, the so-called "Jet break". SanPiN standards prescribe the mandatory organization of an air gap at the place of attachment of the sanitary fixture to the sewer to prevent the entry of pathogenic bacteria and other microorganisms into the sanitary fixture. Usually, neglecting the mentioned standards, the water heater is connected directly to the sewer without organizing an air gap. In some cases, this is due to the fact that there is no possibility and / or place for organizing an air gap. In this case, the risk of harm to health due to infection by pathogens, such as E. coli, is increased. In other cases, when using closed safety valves (1), a water heater may explode and cause flooding, which may result in personal injury through the mechanical parts of the water heater and / or boiling water and property damage. In addition, when using a water heater with open safety valves (1), when the drainage is not organized, flooding of the room may occur when excess pressure is released, which can also cause damage to health and property damage. When using a container (23) for discharge, at least the safety of using a water heater is increased due to the prevention of harm to health, hygiene conditions are observed.

An exemplary embodiment of the proposed invention contained a first pipe (13), a second pipe (14) and a third pipe (15). Obviously, the proposed invention may contain at least one known from the prior art pipe made of at least one known from the prior art material, containing, if necessary, at least one union nut and / or at least one thread (internal and / or external) and made with the possibility of connecting fittings, assemblies, pipes and / or other pipes. At least one pipe can be made, for example, metal (copper, etc.), of plastic. In addition, at least one pipe must be resistant to high temperatures, i.e. ensure the passage of hot water. It is obvious that the configuration of at least one pipe (its shape, dimensions, etc.) may be different from that described above in the description and drawings. The use of at least one thread and at least one union nut can simplify the assembly of the proposed invention and increase the tightness and reliability of the joints. It is also obvious that, if necessary, for connecting two devices (for example, safety valves (1) and stop valves (33), safety valves (1) and a drain assembly (6), a drain assembly (6) and a tank (23) for collecting drainage , drain unit (6) and water heater, water heater and three-way valves (28), three-way valves (28) and check valves, etc.), at least one pipe can be used between each other.

It will be apparent to those skilled in the art that as a stop valve (33), any piping fittings known in the art can be used that are capable of shutting off the water flow, for example, a valve, valve, tap, butterfly valve, etc. In addition, shutoff valves (33) can be connected to safety valves (1) via at least one pipe.

An exemplary embodiment of the proposed invention contained three-way valves (28) and non-return valves. Obviously, in other embodiments, three-way valves and / or non-return valves may be absent.

It should be noted that the term “pipe to connect with ...” should be understood to mean a pipe designed and configured to connect to a specific part of another device by directly interacting with it and / or using at least one additional device, such as a pipe. For clarity, for example, in an exemplary embodiment of the invention, the first inlet pipe (9) for connecting to the outlet pipe of the safety valve (1) is configured to directly connect to the outlet pipe (3) of the safety valve (1).

The above-described example of performing work and using the proposed invention demonstrates the solution of the specified technical problem and the achievement of the specified technical result. In addition, an increase in operational reliability, safety of use, an expansion of the arsenal of certain equipment can be achieved, simplified assembly and increased installation speed are achieved, the risk of leaks at the connection points of devices is reduced, the dimensions of the water heater kit are reduced, the load on maintenance personnel is reduced, and manufacturability is improved construction kit for connecting a water heater. The mentioned advantages of using the proposed invention are achieved, inter alia, due to the special design of the drainage unit (6), in which a single outlet for drained water and water formed during the discharge of excessive pressure inside the water heater is organized. The use of the described drainage unit (6) allows replacing the use of at least one branch pipe, a tee connected to the safety valves of the water heater, and drain valves connected to the tee by means of the at least one pipe. In addition, the use of three-way valves (28) instead of the usual shut-off valves (as in the well-known analogue) made it possible to organize the flow of air into the water heater when emptying it without dismantling the kit for connecting the water heater, which significantly increased the drain rate, as well as maintaining the possibility of shutting off water.
