The proposed technical solution is a collection of products intended to be used together to perform a general functional purpose, namely, the introduction of a heating radiator known from the prior art (or connecting it, connecting it to a pipeline). Products included in the proposed technical solution can be stacked at the manufacturer in one styling device, for example, a case, box, etc. In addition, to simplify and ease packaging and assembly, the proposed technical solution can be disassembled into individual products.

The proposed technical solution can be used to connect a heating radiator on both the right and left sides. The following is a description of the assembly, use and operation of a preferred embodiment of the proposed technical solution for heating systems with top filling when connected to the right side of the heating radiator. The complete set of devices is a unit for connecting a heating radiator.

When assembling the first pipe fittings (1a), its kinematic element (24a) is placed in the opening of the cover (10a). When assembling the second pipe fittings (1b), its kinematic element (24b) is placed in the opening of the cover (10b).

Actuators (9) are connected to pipe fittings (1).

The first ridge (3a) and the second ridge (3b) are connected to the heating radiator by means of a threaded connection formed by means of fasteners, which are external threads (41): fasteners for the exhaust (3a) are connected to the connecting pipe of the radiator, and fasteners for the exhaust ( 3b) are connected to the second connecting pipe of the heating radiator.

To the pipe fittings (1) connect the drives (3). For example, the flare (3a) is connected to the second connecting pipe (12a) of the first pipe fitting (1a) by means of a threaded joint formed between the internal thread (not marked in the figures) of the union nut (4a) and the fastening means of the second connecting pipe (12a), representing an external thread (16a), and the flare (3b) is connected to the second connecting pipe (12b) of the second pipe fitting (1b) by means of a threaded joint formed between the internal thread (not marked in the figures) of the union nut (4b) and fastening means of the second connecting pipe (12b), which is an external thread (16b).

Two compression ring nuts (5) are put on the connecting tube (27), and then two compression rings (6), the first compression ring (6a) is located under the first compression ring nut (5a), and the second compression ring (6b) is located under the second compression nut (5b). Also, a narrowing insert (7) is installed in one of the ends of the connecting tube (27). Next, the bypass (2) is connected to the pipe fittings (1) by means of the aforementioned compression nut (5). The first compression nut (5a) is connected to the first pipe fitting (1a) by forming a threaded connection between the fastening means of the fourth connecting pipe (14a) of the first pipe fitting (1a), which is an external thread (18a), and an internal thread (not marked on Figures) of the first crimp union nut (5a). The second compression nut (5b) is connected to the second pipe fitting (1b) by forming a threaded connection between the fastening means of the fourth connecting pipe (14b) of the second pipe fitting (1b), which is an external thread (18b), and an internal thread (not marked on Figures) of a second crimp union nut (5b). If necessary, the length of the bypass (2) is changed, for example, by cutting off part of the connecting tube (27).

To limit the movement of the bypass (2) into the cases (9) of the pipe fittings (1), each of them contains an internal annular stop (35) located inside the fourth connecting pipe (14): the first pipe fittings (1a) contains an annular stop (35a), and the second pipe fitting comprises an annular stop (35b). The stop (22a) of the cover (10a) of the first pipe fitting (1a) is configured to connect (contact) with the end of the portion (13a) to attach the cover (10a) of the first pipe fitting (1a) in order to limit the movement of the cover (10a) of the first pipe fittings (1a) into the body (9a) of the first pipe fittings (1a). The stop (22b) of the cover (10b) of the second pipe fitting (1b) is configured to connect (contact) with the end of the portion (13b) for attaching the cover (10b) of the second pipe fitting (1b) in order to limit the movement of the cover (10b) of the second pipe fittings (1b) into the housing (9b) of the second pipe fittings (1b). The stop (33) of the narrowing insert (7) is made with the possibility of connection (bringing into contact) with the end of the connecting tube (27) in order to limit the movement of the narrowing insert (7) inside the connecting tube (27), fix the narrowing insert (7) and ensure simplicity its extraction. Each stop (35) of the pipe fittings (1) is made with the possibility of connection (bringing into contact) with the end of the bypass (2), while the ends of the connecting tube (27) abut against the mentioned internal stops (35) of the pipe fittings (1). The stops mentioned above prevent the product from moving inside another product.

The first connecting pipe (11a) of the first pipe fitting (1a) is connected to the pipeline by means of a fastening means, which is an internal thread (15a). The first connecting pipe (11b) of the second pipe fitting (1b) is connected to the pipe by means of a fastening means, which is an internal thread (15b).

When connecting the devices or parts of the devices of the kit to each other to ensure sealing, at least one prior art sealing means, for example at least one prior art gasket, can be used. In particular, the node for connecting the heating radiator contains the said sealing means, which can be located on the locking elements (26) of the pipe fittings (1), the said crimp rings (6) made of elastic (polymer) material, ring gaskets (36) for additional sealing of the connection between the moans (3) and the second connecting pipes (12) of pipe fittings (1). A first annular gasket (36a) is placed between the first ridge (3a) and the first pipe fitting (1a), and a second annular gasket (36b) is placed between the second ridge (3b) and the second pipe fitting (1b). The node for connecting a heating radiator preferably contains two additional ring gaskets (36): a third ring gasket for additional sealing of the connection between the third chute (3c) and pipe fittings (1) and a fourth ring gasket for additional sealing of the connection between the fourth chute (3d) and pipe fittings (1). Obviously, when connecting the unit to connect the heating radiator to the pipeline ("riser") and the heating radiator, additional sealing means can be used. In this case, the shafts (3) and covers (10) preferably contain grooves for accommodating said annular gaskets. The said grooves ensure the correct placement of the annular gaskets, for example, prevent their loss, which provides sealing and additional reliability of the node for connecting the heating radiator.

The preferred version of the node for connecting a heating radiator works and is used as follows.

The working medium (coolant) received from the pipeline into the first connecting pipe (11a) of the first pipe fitting (1a) enters the second connecting pipe (12a) of the first pipe fitting (1a), and a small amount of it enters the fourth connecting pipe (14a) first pipe fittings (1a), and then bypass (2). The working medium from the second connecting pipe (12a) of the first pipe fittings (1a) through the drain (3a) enters the heating radiator. The working medium from the heating radiator through the second bend (3b) enters the second connecting pipe (12b) of the second pipe fitting (1b). Then, the working medium from the second connecting pipe (12b) of the second pipe fitting (1b) enters the first connecting pipe (11b) of the second pipe fitting (1b). The working medium from the first connecting pipe (1b) of the second pipe fittings (1b) enters the pipeline. For clarity, in this case, the first connecting pipe (11a) of the first pipe fitting (1a) is an inlet pipe, the second connecting pipe (12a) of the first pipe fitting (1a) is the first outlet pipe, the fourth connecting pipe (14a) of the first pipe fitting ( 1a) represents the second outlet pipe, and the first connecting pipe (11b) of the second pipe fitting (1b) represents the output pipe, the second connecting pipe (12b) of the second t the pipe fittings (1b) represents the first inlet pipe, the fourth connecting pipe (14b) of the second pipe fittings (1b) represents the second inlet pipe.

By means of the first actuator (8a) connected to the first pipe fittings (1a), or the second drive (8b) connected to the second pipe fittings (1b), the flow area of the first pipe fittings (1b) is adjusted.

The solution of the noted technical problems and the achievement of the technical result are shown above in the preferred embodiment of the proposed utility model. However, it should be noted that the above detailed description with reference to the accompanying drawings is given in order to clarify the essence of the proposed technical solution and is an exemplary embodiment of its implementation. Other options for implementing the features of the proposed technical solution are obvious, for example, different from those presented in the drawings, by means of well-known and prior art material and technical means, not going beyond the essence of the proposed technical solution and the scope of legal protection determined by the formula.

When using the proposed technical solution, an increase in operating convenience, increased reliability and ease of installation is achieved, for example, due to the unification of components. In addition, an expansion of the arsenal of means for a certain purpose was implemented, namely, the proposed technical solution has a new design, different from the existing ones. In particular, in the proposed technical solution, 8 connections between products (devices) were used, against 12 in existing ones. In addition, in the case of a bottling, there is no need for dismantling or reassembling the assembly, which increases reliability, in particular operational, and ease of use.

. Однако следует учитывать, что упомянутая выше заужающая вставка (7) предназначена для создания сопротивления на пути движения теплоносителя в байпас (2) для обеспечения правильной работы (чтобы практически вся рабочая среда поступала в радиатор отопления), и в других вариантах выполнения предложенного технического решения может представлять собой часть байпаса (2), т.е. выполнена заодно с какой-либо его деталью и представляет собой, например, заужение в соединительной трубке (27). Заужающая вставка (7) полностью или ее часть выполнена со возможностью размещения в байпасе (2), при этом предпочтительно, чтобы заужающая вставка была (7) расположена на одном из концов байпаса (2), т.к. это упростит сборку узла для подключения радиатора отопления. Например, при использовании в качестве сгона (3), предназначенного для соединения первой трубопроводной арматуры (1а) и радиатора отопления, сгон

, как в предпочтительном варианте выполнения предложенного технического решения, внутренний диаметр байпаса (2) - его проходное сечение - может быть больше, чем в упомянутом сгоне (3а). В этом случае значительная часть теплоносителя будет проходить по байпасу (2), минуя радиатор отопления. При использовании других известных из уровня техники стонов (3), например, сгона (3с) и/или сгона (3d), проходное сечение которых больше проходного сечения байпаса (2), для соединения первой трубопроводной арматуры (1а) и радиатора отопления заужающая вставка (7) не применяется. Очевидно, что сгоны (3) предназначены для соединения закрепленных устройств, которые нельзя поворачивать. В некоторых случаях радиатор отопления невозможно установить («навернуть») на уже установленную трубопроводную арматуру (1), соединенную с подводящей трубой трубопровода, т.к. можно нарушить герметичность по меньшей мере одного соединения, что уменьшит эксплуатационную надежность.In other embodiments, the implementation of the proposed technical solution can be used at least one well-known from the prior art, the curve (3), while at least one curve (3) is configured to connect with at least one connecting pipe of at least one pipe fittings (one). For example, at least one sgon (3) is a sgon

. However, it should be borne in mind that the narrowing insert (7) mentioned above is designed to create resistance on the path of the coolant in the bypass (2) to ensure proper operation (so that almost the entire working medium enters the heating radiator), and in other embodiments of the proposed technical solution, represent part of the bypass (2), i.e. made integrally with any of its parts and is, for example, narrowing in the connecting tube (27). The narrowing insert (7) is completely or part of it can be placed in the bypass (2), while it is preferable that the narrowing insert (7) is located at one end of the bypass (2), because this will simplify the assembly of the unit for connecting the heating radiator. For example, when used as a runaway (3), designed to connect the first pipe fittings (1a) and a heating radiator, runaway

, as in the preferred embodiment of the proposed technical solution, the internal diameter of the bypass (2) - its flow area - may be larger than in the said run (3A). In this case, a significant part of the coolant will pass through the bypass (2), bypassing the heating radiator. When using other moans (3) known from the prior art, for example, runaway (3c) and / or runaway (3d), the passage section of which is greater than the bypass section (2), for connecting the first pipe fittings (1a) and the heating radiator, narrowing insert (7) not applicable. Obviously, the bends (3) are designed to connect fixed devices that cannot be rotated. In some cases, the heating radiator cannot be installed (“screwed on”) onto the already installed pipe fittings (1) connected to the supply pipe, as the tightness of at least one joint can be compromised, which will reduce operational reliability.

Obviously, other bypass options are also possible (2). For example, in other embodiments of the proposed technical solution, the passage section of the bypass section (2) may be less than the passage section of the bypass (3) intended to connect the first pipe fittings (1a) and the heating radiator. In this case, the narrowing insert (7) is also not used.

In other embodiments, the proposed technical solution contains at least one known from the prior art flare nut (4) made with the possibility of connection with at least one connecting pipe of at least one pipe fitting (1). At least one additional union nut (4) can also be used to connect the first pipe fittings (1a) and / or the second pipe fittings (1b) to the pipe. In addition, at least one compression nut (5) may be located on the bypass (2), at least one union nut (4) may be located on at least one run (3). The union nut (4) or the union crimp nut (5) allows mounting / dismounting of two devices without rotating them, which improves operational reliability and does not violate the tightness of other connections.

It is obvious that in other embodiments, at least one connecting pipe of at least one pipe fitting (1) or bypass (2) and / or at least one pipe (3) may comprise at least one fixing means known in the art. . The fastening means is intended for fastening two devices (objects, products, parts) and can be a fastening means known from the prior art. For example, at least one fastening means of at least one pipe fittings (1) and / or bypass (2) and / or at least one run (3) may be an external thread, an internal thread, a union nut, at least one fastener known in the art and / or the like. At least one flange (3) is configured to connect with at least one connecting pipe of at least one pipe fitting (1), with at least one pipe (3) and at least one connecting pipe of at least one pipe fittings (1) can be connected in a conical connection. The conical connection does not require sealing means, for example, gaskets, and is more resistant to temperature extremes and deviations of the axes of the connected sections, therefore it is preferable to ensure tightness and increase operational reliability.

It is obvious that in other embodiments of the proposed technical solution, at least one pipe fitting (1) and / or bypass (2) and / or at least one discharge (3) and / or at least one cover (11) may contain at least one emphasis, made for example, an annular shoulder, shoulder, ledge, annular ledge, etc.

Preferably, the actuator (9) is a manual actuator, but may be any other actuator known in the art configured to be connected to pipe fittings, for example, electromagnetic (e.g., electric, electromagnetic), hydraulic (e.g., hydraulic), pneumatic (for example, pneumatic actuator) or their combination (combined drives, for example, pneumatic actuator, electro-hydraulic actuator, etc.). The drive (9) can also be a handle, a flywheel, etc.

In other embodiments of the proposed technical solution, at least one pipe fitting (1) may be a valve or a butterfly valve. It is obvious that at least one part of at least one pipe fittings (1) may be different from those shown in the Figures, for example, cases (9) of pipe fittings (1) can be made different.

The kinematic element (24) of at least one pipe fitting (1) may be a spindle or rod.

Also in other embodiments, the pipeline valves (1) can be made unequal, for example, in size, structure and other structural characteristics. In addition, the housing (9a) of the first pipe fittings (1a) and the housing (9b) of the second pipe fittings (1b) can be symmetrical, which will greatly simplify the assembly of the kit into a node for connecting a heating radiator, as well as ensure unification and interchangeability elements (products).

The proposed technical solution may contain at least one known from the prior art sealing means, for example, made from the prior art flexible, polymeric material, and intended to seal the connection between at least two parts. For example, in other embodiments of the proposed technical solution, the sealing means may be additionally located between the cover (10) and the housing (9) of at least one pipe fitting (1).
