Technological Area:
[0001] The invention is relating to the thermostatic valve installation part providing entrance of a fitting to the panel radiator both from below and through center of panel radiator. This fitting enables the entry into the panel radiator as well as circulation in the panel radiator of the hot water. The characteristic of this part is that as it provides a center-connection to the panel radiator, thus, providing an easy assembling from the right and left and consists of two parts, namely, installation upper group and lower group. Therefore, because of the adaptation of hot water pipe to various length and the modular structure of it, when required, the weld assembly can be made providing an easiness in stocking and conveying and, thus, minimizing costs of stocking.
[0002] In case single-pipe version in place of two-pipe version is used in installation lower group, an additional advantage in material cost-saving is obtained.
[0003] Since the passes in the piping are spherical and radius-twisted, a smooth flow is provided by decreasing internal flow resistance and, thus, sounds originating from turbulence during flow arc dissipated.
The Current State of the Technique
[0004] During the circulation of hot water in the panel radiators, owing to the manufacturing and combining method, the fittings used for the water flow and return by means of combined piping cause the low quantities of production in the unit time. Meanwhile, since two distinct pipes are used for inlet and outlet with the installation lower group, excess material is not used. Because of these reasons, cost of installation is found high.
[0005] Moreover, since the valve installations of particular size is required for panel radiators of particular height and length, cost of stocking is increased.

An Illustration of the invention
[0008]
Figure 1 : The position of a version of the invention on the panel radiator is exhibited.
Figure 2 : In the version of thermostatic valve installation part, the position of which on the panel radiator is shown in Figure 1; the flow to upper installation group of the hot water in the panel radiator chasing (1) is performed by means of the inter-fitted pipe VCP (2), and the returning cold water is conducted through inter-fitted pipe HCP(3) to installation lower group (B) by means of valve box group (9). The connection between installation upper group (A) and installation lower group (B) is accomplished by means of inter-fitted pipes of VCP (2) and HCP (3), respectively. Modular inter-fitted pipes (12) are fitted to the VCP (2) and HCP (3) pipes according to the length of panel radiator so as to provide sealing, being connected to each other with the welded assembling method. Thanks to the small spherical segments (10) contained in the installation lower group, a smooth flow with the exit of hot water and the return of cold water is established. Since there is no turbulence occurred throughout the process, there is no any sound coming out of the radiator.
Figure 3 : Position of the single-line thermostatic valve installation part on the panel radiator.
Figure 4 : : In the version of thermostatic valve installation part, the position of which on the panel radiator is shown in Figure 3; the most important aspect is that the flow of hot water from lower installation group to upper installation group is provided by means of a single inter-fitted pipe. The return of cold water is supplied by means of the collector (K) in the lower installation group. The inter-fitted pipe VCP (2) and the modular inter-fitted pipe HCP (3), which is variable according to the radiator lengths, are united by welded-uniting method, thus, obtaining a single line. During the mounting of thermostatic valve part (13) on the panel radiator (1), a smooth mounting is established using support part (14) and thus the slipping down of thermostatic valve part is prevented. There are two different types of this version dependent on the lower installation group (B), panel radiator (1) being on the right hand side or left hand side of the thermostatic valve.
Figure 4 (LEFT), Figure 4 (RIGHT) In all the versions; thermostatic valve part (13) existing in the upper installation group (A) connects to the valve scat at the end of insertion part in three different forms. These three different application is illustrated in Figure 2 (C, D, E). Valve seat is mounted on the valve casing in three different weld fittings illustrated in Figure 2 (F,G,H).
[0009] In the case of Figure 2(C), the fitting of thermostatic valve part (12) to valve seat at the and of insertion part has an external o-ring scaling.
[0010] In the case of Figure 2(D), thermostatic valve part (12) operates when a plastic plug piece in the vent presses on the top of the valve scat (7) located at the end of insertion part.
In the case of Figure 2(E), the fitting of thermostatic. valve part (12) to valve seat at the and of insertion part has an internal o-ring scaling.
In the case of Figure 2(F), this valve seat (7) and weld insertion part(1) are welded, and then the end of connection pipe is upset in shape of ring for welding (8), and consequently the upset section is welded with the insertion part.
