Description

The invention relates to means for heating premises, used mainly in construction.

Radiators are known, each of which includes a section with a thermostatic valve, and the section contains an upper tube to which the lower tube of the section is rigidly connected with a vertical tube, while the upper tube of the section forms the upper pipe with the other upper pipes of other sections of the radiator, the lower pipes form with the other lower tubes of other sections the lower line for the coolant, and a thermostatic valve installed in the upper tube of the radiator section [1-8].

In the radiators [1, 8] adjacent upper and lower tubes of the sections are connected by threaded connecting sleeves, the thermostatic valve and the control valve (control and connecting headset) are located outside the radiator on the bypass tube.

Outside of the radiator [4] in its lower part there is a multichannel hydraulic distributor connected by a vertical tube with a thermostatic valve for lower and lateral coolant supply to the radiator.

In the known technical solution [8], a thermostatic valve and a control valve (control and connecting headset) are located outside the radiator.

Of the known technical solutions, the closest to the technical solution presented in this description is a radiator with a thermostatic valve, containing tubular sections interconnected by threaded bushings, each of which is made of upper and lower tubes connected by vertical tubes, while in the upper tube of the outer section is installed thermostatic valve, and at least one lower inlet and one side opening are made in the lower tube of the extreme section, while rhnie and lower tube sections form the upper and lower lines, communicating with each other by vertical tubes [8].

Essential for ensuring the radiator’s efficiency is the efficient operation of the thermostatic valve, which depends on the supply of the heat carrier directly to the working chamber of the thermostatic valve at the radiator inlet before the heat transfer to the radiator sections. Another important component from the point of view of the direction of the coolant to the thermostatic valve is the location of the channel supplying the coolant to the valve.

The technical result of this solution is to increase the efficiency of the radiator.

The solved and achieved task of this technical solution is to increase the versatility of the radiator and its efficiency.

To achieve this technical result, in a radiator with a thermostatic valve, containing tubular sections interconnected by threaded bushings, each of which is made of upper and lower tubes connected by vertical tubes, a thermostatic control valve is installed in the upper tube of the extreme section, and in the lower tube of the extreme sections made of at least one lower inlet and one side hole, while the joined upper and lower tubes of the sections form the upper and lower pipes, interconnected by vertical tubes, a partition is installed in the lower tube of the extreme section in front of the threaded sleeve, dividing the cavity of the lowermost tube of the extreme section into two parts, one of which is connected with the lower inlet, the vertical tube of the extreme section and the specified side hole, and in the other part of the divided cavity of the lowermost tube is a partition and a threaded sleeve, while the partition is made cylindrical, with a thread on its outer surface screwed into the thread, made under the threaded sleeve, docked with the end face of this sleeve and is located between the connector line of the lower tube of the extreme section and the lower tube of the adjacent section, and in the upper tube of the extreme section in front of the thermostatic valve there is a control valve that divides the cavity of the extreme upper tube into two parts, in one of which a thermostatic valve is installed, and in another part of the cavity there is a threaded sleeve connecting the adjacent upper tubes, and a central channel communicating vertical pipe of the expansion valve, and a horizontal channel communicating said divided parts at the top of the tube cavity.

Figure 1 shows the radiator with a thermostatic valve, figure 2 - thermostatic valve and valve in the upper extreme tube of the outermost section of the radiator, figure 3 - plug and partition in the lower extreme tube of the outermost section of the radiator.

The radiator with a thermostatic valve (Fig. 1) is made of two extreme tubular sections 1 and several intermediate sections 2. Adjacent sections of the radiator are interconnected by threaded bushings 3 screwed into the upper adjacent tubes 4 and the lower adjacent tubes 5 sections. Each upper tube 4 is connected by a vertical tube 6 to each lower tube 5 of any of the sections of the radiator.

In the upper tube 4 of the extreme left (according to the drawing) section 1, the body of the thermostatic valve 7 is installed (Fig. 2), and in the lower tube 5 of the extreme left section 1, at least one threaded lower hole 8 or two lower threaded holes 8 and one side threaded hole 9. The threaded side holes 9 are also made in the other end tubes 5. All of these threaded holes of the end tubes 5 are threaded nipples for fastening therein means for connecting the heating system pipes to the radiator, in particular for fastening I have pipes or plugs in them.

The joined upper and lower tubes of the sections form, respectively, the upper and lower lines 10 and 11 (Fig. 1), interconnected by vertical tubes 6. In the lower tube 5 of the leftmost section, a partition 12 is installed in front of the threaded sleeve 3, separating the cavity of the lowermost tube 5 extreme sections in two. One part 13 of the specified cavity is in communication with the lower hole 8, the vertical tube 6 of the leftmost section 1 and the specified side hole 9 of the lower tube 5 of the leftmost section 1. In the other part 14 of the divided specified cavity of the lowermost tube 5 there is a partition 12 and part of the threaded sleeve 3 The partition 12 is made cylindrical, with a thread on its outer surface, screwed into the thread 15 of the lower end tube 5 (figure 3). The thread 15 is made under the threaded sleeve 3 and the thread of the baffle 12. The baffle 12 (Fig. 1) is docked with the end of the threaded bushing 3 and is located between the connector line 16 of the lower tube 5 of the extreme section and the lower tube 5 of the adjacent section.

In the lower tube 5 of the intermediate section 2 of the radiator adjacent to the leftmost section 1, an additional lower inlet 8 is made (right in the drawing, FIG. 1).

In the upper tube 4 of the leftmost section in front of the thermostatic valve 7, the valve body 17 is installed, and this body divides the cavity of the upper upper tube 4 in two. In one part 18 of the cavity of the upper tube 4, a thermostatic valve 7 is installed, in the other part 19 of the specified cavity of the upper tube there is a threaded sleeve 3 connecting the adjacent upper tubes 4.

In the valve body 17 (FIG. 2), a central channel 20 is made, communicating the vertical tube 6 with a thermostatic valve 7, in particular with its working chamber, in which a thermocouple (not shown) is located. At least one additional horizontal channel 21 is made in the valve body 17, communicating parts 18 and 19 of the divided cavity of the upper tube 4. Channel 21 is optional. The through section of the horizontal channel is less than the through section of the central channel.

Each extreme upper tube 4 and each extreme lower tube 5 (Fig. 1) have threads 22 on the inner surfaces for a plug 23 or for a thermostatic valve 7, or for connecting elements (not shown) connecting the radiator to the pipes (not shown) of the heating system . The lower holes 8 have a thread 24 on the inner surfaces (Fig. 1) for connecting valves 25 and 26 for the lower coolant supply. In the control valve 17, a window 27 is made, which is communicated through channel 28 with an additional horizontal channel 21.

The radiator works as follows.

If connecting valves 25 and 26 are installed in the threaded lower inlet openings 8, a thermostatic valve 7 is installed in the threaded hole of the upper tube 4 of the leftmost radiator section 1, a control valve is installed in the cavity of the upper tube 4, and a plug 23 is installed in the lower extreme tube 5, then the radiator It can be included in a one-pipe heating system, which is characterized by a single pipe for supplying and removing the coolant through the radiator.

If plugs (not shown) are installed in the threaded lower inlet openings 8 instead of the shown connecting valves 25 and 26, the thermostatic valve 7 and the control valve 17 are removed, the radiator can be included in a one-pipe or two-pipe heating system with lateral coolant inlet.

If connecting valves 25 and 26 are installed in the threaded lower inlet openings 8, and the thermostatic valve 7 and the control valve 17 are removed, then the radiator can be included in a single-pipe and two-pipe heating system with a lower coolant supply to the radiator. In this case, other combinations of connecting a radiator are also possible.

In the presented radiator layout solution, shown in Fig. 1, when the plug 23 is removed, the coolant passes through the upper and lower pipes 10 and 11, the tubes 6 on the right side of the partition 16, and then leaves the radiator through the lower side hole 9 of the extreme section of the radiator.

If it is necessary to connect the heating system pipes to the radiator from below, remove the plugs from the radiator and install adjustable valves 25 and 26 in their place, then connect the inlet and outlet pipes of the system (not shown) with them, and insert the plugs in the side lower and lateral upper openings 9 23. In the first case, when connecting the heating system pipes to the radiator from below, the coolant from the inlet pipe of the heating system passes through an adjustable valve 26 to the right of the partition 12, through the lower pipe 11 and pipes 6, located ditch from the partition 12, the upper line 11, the pipe 6, located to the left of the partition 12, and through the adjustable valve 26 goes into the outlet pipe of the heating system.

In the second case, when connecting to the radiator of the heating system pipes from below, the coolant from the inlet pipe of the heating system passes through an adjustable valve 25 to the left of the partition 12, then through line 10 and tubes 6 to the lower pipe 11 and exits through the adjustable valve 26 into the discharge pipe heating systems

Similarly, the coolant can be introduced into the radiator through the lower or upper side openings 9.

If the thermostatic valve 7 and the control valve 17 are installed in the radiator, then when a heat carrier, for example, hot water under pressure, is supplied through the radiator inlet 8 to the left of the partition 12, the coolant fills the space between the partition and the plug 23, passes upward through the vertical tube 6 through the central channel 20 of the control valve 17 and its window 27 is directed to the thermostatic valve 7. In this case, the working cavity formed by the hydraulic control valve 17 and the thermostatic control valve 7 distributes heat the carrier fluid in two flows, one of which enters the working chamber of the thermostatic valve 7, where it heats the thermosensitive element that controls the flow rate of the coolant supplied to the radiator, and the other coolant flow passes through channel 28, the horizontal additional channel 21 of the control valve 17 to the upper line 10 of the radiator and through it extends through vertical tubes of 6 sections of the radiator in the lower pipe 11 of the radiator. The coolant fills the radiator, transfers heat to it, leaves the radiator through the hole 8, located on the right side of the partition 12, and enters the next radiator of this system through the heating system pipe.

In the process of heat exchange, the temperature of the coolant, radiator and the environment in which the radiator is located changes. In accordance with the indicated temperature changes, the temperature of the thermosensitive element of the thermostatic valve changes. However, when the coolant is supplied to the thermostatic valve practically at the radiator inlet, first of all, the temperature of the heat-sensitive element changes depending on the temperature of the coolant introduced into the radiator, which contacts directly with the heat-sensitive element of the thermostatic valve. This leads to an increase in the accuracy of adjusting the heat transfer from the radiator to the heated room, the efficiency of redistribution of heat between the radiators of the heating system of the premises, eliminating overheating and reducing heat loss.

In fact, the presented radiator is to the maximum extent universal, with the possibilities of optimal redistribution of heat in the heating system between other radiators.
