Description

The inventive utility model relates to heating devices for central water heating systems, in particular to sectional aluminum and bimetallic radiators, the sections of which are connected with bushing nipples having the ability to connect the supply and outlet pipes from below.

Known radiator with a lower connection to the heating system (RU patent for utility model No. 145411, publ. 09/20/2014) containing interconnected sections with vertical and horizontal pipelines, an upper flow distributor with a thermostatic valve and a lower flow distributor installed in horizontal pipelines extreme section of the radiator. When the sections are connected via bushing nipples, the upper flow distributor rests against the bushing with a sealing element and a spring is used as a stabilizing element. The lower flow distributor prevents the coolant from moving directly to the second section and redirects it along the vertical pipeline to the upper flow distributor. After passing through it, the coolant goes to the next section of the radiator and in the process of circulation moves to the outlet pipe. Depending on the method of controlling the thermostatic valve (manual or automatic), the valve passes the coolant at a given either constant or variable flow rate over a period of time.

A disadvantage of the known radiator is the device of the lower flow distributor that impedes the movement of the coolant immediately into the second section, because it is complex and expensive. In addition, its use leads to a separate operation during assembly - it is necessary to install it.

Closest to the claimed solution, selected by the Applicant as a prototype, is a radiator for central water heating systems (RU patent for utility model No. 74695, published July 10, 2008), comprising a lower connection to the system, sections with vertical and horizontal pipelines, connected between each other through passage nipples, and a thermostatic device that provides automatic control of the flow of coolant through the radiator and connected to the radiator through the connecting tube. As the connecting tube, the vertical pipe of the extreme section of the radiator is used, which is equipped in the upper part with a sealed device with a channel for the passage of the coolant and a seat for connecting the thermostatic device, and the extreme section is separated from the other sections of the radiator from below by a blind nipple. A sealed fixture in the upper horizontal pipe and a blank nipple in the lower horizontal pipe are means of distributing the heat carrier flow.

Unlike the solution according to patent RU145411, in the solution according to the prototype there is no separate device for the lower flow distributor and a nipple that is a through (passage) between the end section and the subsequent section, both devices are replaced by one blind nipple, therefore, during assembly, there is no additional operation for screwing the lower flow distributor, as you only need to screw in the blind nipple instead of the through nipple and screw the plug. However, the disadvantages of the known device are the technological features of the assembly in terms of the installation in the upper horizontal pipe of a sealed device having a channel for the passage of the coolant and a seat for connecting the thermostatic device. It is necessary to ensure high accuracy of the joining of the elements and the fastening force, as a result of which the laboriousness of the assembly increases, and as a result, maintainability deteriorates.

The objective of the claimed utility model is to reduce the complexity of the assembly of a sectional radiator with a lower connection and increase the reliability of its operation.

The problem is solved in that a sectional radiator with a lower connection to the heating system, containing connected to each other sections of the radiator, each of which has a vertical collector and the upper and lower horizontal collectors connected to it, the lower horizontal collectors of the extreme and subsequent sections are connected through the sealing gasket with a blind nipple, the remaining horizontal section collectors are connected with bushing nipples, the extreme and subsequent sections have the ability to connect their own bottom horizontal collectors respectively to the inlet and outlet nozzles of the lower connection to the heating system, the upper horizontal collector of the extreme section is made with a device for connecting a temperature control device, characterized in that the device for connecting a temperature control device is represented by a flow guide into which the valve insert is screwed in with the possibility of switching with a temperature control device, the flow guide is equipped with an external thread for mounting an upper horizontal manifold at the section, and has a smooth end portion for connection into interference with an inner surface of the pin passage connecting the upper horizontal manifold and at subsequent sections, the entrance nipple has an internal cylindrical bore.

As a temperature control device for connection to a flow guide, a temperature control head can be used.

The radiator sections may preferably be made of AK12M aluminum alloy reinforced with collectors made, for example, of steel 10.

The lower horizontal collectors of the extreme and subsequent sections have adapters for connecting, respectively, to the inlet and outlet pipes of the lower connection to the heating system. To do this, the extreme and subsequent sections of the radiator have prismatic tides in which a threaded hole is made for installing the lower connection adapter.

The vertical and horizontal section manifolds may preferably be made of steel 10.

The horizontal collectors are connected to each other by means of a threaded connection with nipples having an external thread installed inside the horizontal collectors at the junction of their edges. Connection with passage nipples is carried out through the sealing (intersectional) laying.

The blind nipple, which connects the lower horizontal collectors of the extreme and subsequent sections, prevents the coolant from entering the lower horizontal collector of the subsequent section and redistributes its flow into the vertical collector of the extreme section. Thus, the coolant enters the lower horizontal collector of the next section, passing through all the radiator headers, and then is discharged through the outlet pipe of the lower connection to the heating system.

The flow guide, which serves to distribute the flow to the upper horizontal collectors of the subsequent sections, can preferably be made of thermosetting. The flow guide is screwed into the upper horizontal collector of the end section by means of a threaded connection so that its smooth end part is placed inside the passage nipple connecting the upper horizontal collectors of the extreme and subsequent sections. A valve insert is screwed into the flow guide, providing the ability to adjust the flow rate of the coolant. The valve insert provides switching from the thermostatic head to automatically control the flow rate of the coolant depending on the temperature and ensure a comfortable room temperature for the user.

Sectional radiator with a lower connection to the heating system can have two versions: left and right. Depending on this, the term “extreme section” is applied to the section located first to the left or right, respectively, and the lower horizontal collector of which can be connected to the inlet of the lower connection unit to the heating system. The term "subsequent section" is applied to the section following the last, lower horizontal collector which has the ability to connect to the outlet pipe of the lower connection to the heating system.

The technical result of the claimed utility model is to ensure the accuracy of the connection of the upper horizontal collector of the extreme section with the device for mounting the thermostatic device due to the quick and reliable fixation of this device in the upper horizontal collector.

In comparison with the prototype, in the inventive radiator, it is much easier to dock the vertical collector of the extreme section with the device into which the temperature control device (the connection point of the temperature control device) is mounted, due to the different design of the connection points of the temperature control device. In addition, not only the installation process is simplified, but also the maintenance of the connection point of the thermostatic device. In the claimed solution, the connection node of the thermostatic device is made in the form of a flow guide, into which a valve insert is screwed in, which has the ability to commute with the thermostatic device (thermostatic head). The simplicity of joining in the claimed solution is ensured by fast and accurate fixation of the flow guide inside the upper horizontal collector of the extreme section: unlike the prototype, it is fixed not in one but in two points, i.e. not only in the threaded part of the horizontal collector, but also inside the passage nipple connecting the upper horizontal collectors of the extreme and subsequent sections. Thus, docking with a vertical collector does not need to be the end of the device into which the temperature control device is mounted, but the section in its middle, which is quicker, more accurate and easier to dock. The mounting force is not required.

The reliability of the inventive radiator is higher than in the prototype, since the reliability of fixing the valve insert and connecting the thermostatic device is increased, which is especially important in a radiator, where the entire volume of the coolant is guided through a vertical manifold to the specified device. The increased reliability of the connection point of the thermostatic device is ensured, on the one hand, by a threaded connection to the upper horizontal collector section of the extreme section, and on the other hand, by a connection of the smooth end portion of the flow guide with a flow nipple, which, in turn, is fixed by a threaded connection with horizontal collectors extreme and subsequent sections.

Reducing the complexity of the installation of the flow guide with a valve insert screwed into it is ensured by the speed and simplicity of screwing it in, since when screwing the flow guide into the upper horizontal collector of the end section, its end part is quickly and accurately positioned inside the passage nipple connecting the end section to the next one, thanks to the inner cylindrical a groove made in the indicated nipple.

The inventive utility model is illustrated by drawings.

The radiator (Fig. 1, 2) contains sections 14, an extreme section 1, a subsequent section 2, each of which has a vertical collector and upper and lower horizontal collectors communicated with it (the positions in Fig. Are not indicated). The horizontal manifolds of the sections are interconnected using bushing nipples 3, with the exception of the lower horizontal manifolds of the end section 1 and the subsequent section 2, which are articulated with a blind nipple 4. The lower horizontal manifolds of the extreme and subsequent sections are equipped with adapters 8 for connecting to the input and output nozzles of the assembly 15 bottom connection to the heating system (figure 3). In the upper horizontal collector of the extreme section there is a flow guide 11, into which a valve insert 12 is screwed in, which is capable of switching with a thermostatic head (not shown) and provided with a cap 13 at this point (Fig. 1,2). The flow guide 11 is mounted in the upper horizontal collector of the end section by means of a threaded connection, for which it has an external thread, as well as a smooth end part for connection in interference with the inner surface of the bore nipple 3 connecting the upper horizontal collectors of the extreme 1 and subsequent 2 sections, for which the specified passage nipple 3 has an inner cylindrical groove.

Sectional radiator with a lower connection to the heating system can have two versions: left and right. With the left version, the input and output of the coolant is carried out through the extreme and subsequent sections located on the left (Fig. 1). With the right execution - through the extreme and subsequent sections located on the right (figure 2). In other words, the adapters 8 for connecting to the bottom connection node 15 are made at the two extreme adjacent sections. These sections have a prismatic tide in the lower part. After machining (hole drilling ∅ 18.63 and threading G1 / 2'-B), these sections are assembled together by means of a straight nipple 3 in the upper part and a blind nipple 4 in the lower part through the sealing gaskets 5, observing the center-to-center distance between the threaded holes 50 mm. Next, the assembled sections go to the radiator assembly. After assembly and painting, adapters (transitional nipples G1 / 2'-G3 / 4 ') 8 (Fig. 1) are screwed into the extreme adjacent sections. Sealant is applied to the screwed-in threaded part G1 / 2 'before assembly. The brass adapter 8 is screwed and sealed into the lower part of the section, which has a local thickening of 8.5 mm, obtained during the casting of the section, which provides the required strength characteristics of the threaded joint and tightness.

 Next, the final assembly is carried out - screw plug 6, plug 7, nut G1 straight through 9, air vent 10, flow guide 11, valve insert 12, cap 13 (Fig. 1).

The sections are made of AK12M aluminum alloy, the collectors are made of steel 10, and the flow guide is made of thermoset.

The radiator works as follows.

The coolant enters the radiator from the inlet pipe of the lower connection unit 15, namely, to the lower horizontal collector of the end section 1. The blind nipple 4 prevents the coolant from moving into the lower horizontal collector of the subsequent section 2 and redirects it along the vertical pipe of the extreme section to the flow guide 11 with the valve insert 12. Through the outlet of the flow guide 11, located inside the passage nipple 3, installed between the extreme 1 and the subsequent 2 sections, the coolant enters the upper horizontal collector of the subsequent section 2, and, in the process of circulation, moves to the outlet pipe of the lower connection to the heating system. Depending on the method of controlling the valve insert 12 (manual or automatic using an attachable thermostatic head, which can be connected to the inventive radiator), the valve (position not shown in Fig.) Of the valve insert 12 passes the coolant through a predetermined constant or variable flow rate period of time.

The inventive device allows to reduce the complexity of the assembly of a sectional radiator with a lower connection and to increase the reliability of its operation.
