(57) Abstract:Thermostatic upper node radiator valve can be used in the valve housings of at least two types, due to the presence of the adapter. Means mounting the upper node with the possibility of its direct installation on the valve housings of at least two different types. The adapter is placed entirely inside the upper node and is formed of two parts of the rod is arranged to move relative to each other. As a result of this may change the effective length of the rod. 17 C.p. f-crystals, 14 ill. This invention relates to thermostatic upper node of the radiator valve, through which the adapter can be used with the valve housings of at least two types, equipped with means of attachment for installation on the valve body and the valve stem, is made with the possibility of axial movement by means dependent on the temperature of the working element to move in the valve body of the follower spring return spring.Thermostatic radiator valves include a valve body and thermostatic very site contains the work item, filled with substance, expanding with changing temperature and provided with a valve stem for extension of the plunger of the valve housing and, consequently, movement of the closing element of the valve. Expanding substance can be solid, pasty or liquid or even gaseous, or vapor-liquid filler in combination with the setting spring. Since the top node exactly fitted to the valve housing, the calibration of the position of the top node can be performed on the plant (DE, 1907231 A1, class G 05 D 23/12, 1972).Known thermoregulatory the top node of the above type which is adapted to the valve housing of the same type and which can be installed on the valve body of the other type by means of the adapter is placed between the means securing the upper Assembly and the valve body. Such detail as this adapter can easily be lost. In addition, the adapter causes a decrease in the strength of the connection of the upper Assembly with the valve body (EP 0504582, A2, class G 05 D 23/02, 1992).Closest to the device according to the invention is a thermostatic upper unit, performed with the slide being moved in the transverse direction between the valve stem and the upper node and talknow value. Thus, the regulation position to the preset value can be performed faster and easier than using the usual method of control using the rotary knob. Fastening this top node, adapted to the specific valve body and is therefore suitable for use only with the valve housing of this type (DE 2220340A, CL G 05 D 23/12, 1974).The invention is directed to solving the task of creating a thermostatic upper Assembly of the above type which may be used in combination with the valve casing at least two different types and which avoids the problems encountered previously when using the adapter.The technical result is achieved that the temperature-controlled top node, radiator valve, through which the adapter can be used with the valve housings of at least two types, equipped with means of attachment for installation on the valve body and the valve stem, is made with the possibility of axial movement by means dependent on the temperature of the working element to move in the valve body plunger, spring return spring, sogliani buildings of different types, at least two types, when this adapter is formed of two parts of the rod is arranged to move in relation to each other, resulting in a change in the effective length of the valve stem.This invention is based on the fact that if the means of attachment suitable for direct connection to a valve housing with at least two different types, to enable the use of the upper Assembly with the valve housings of at least two different types of adapter must only have the possibility of changing the working length of the valve shaft. Thus, the adapter can be made with smaller structural size and placed inside the top node. It can constantly be in place by putting it in the line of power transmission at each top node, which ensures reliable protection against damage. There is no need to perform the adapter open from the outside for inspection. The immediate setting of the upper node provides a solid attaching it to the valve body. The requirement of suitability of the means of attachment to the valve housing at least two types of the most simply can be satisfied, if these buildings, youseo top node is attached to the end of the valve housing, has the same diameter. In this case, the difference of sizes of valve housings of various types essentially consists in the mechanism. Possible variants of implementation, in which the means of attaching various ways pressed in the axial or radial directions and interact with the clamping surfaces of the valve body, which need not be identical to each other in buildings of different types.The preferred value of the change in length, predefined by regulating parts of the shaft are set so that the calibrated position of the upper node is suitable for valve housings of both types. Thus, the calibration of the upper Assembly can be produced in the factory. This calibration is the same for valve housings of various types that can be attached to the upper node.It is reasonable to provide one part of the rod is displaced in the axial direction of the support surfaces interconnected by means of bevel and selectively interacting with mating surface of another part of the stem, the result of the relative movement. The required change of the working length of the valve shaft is achieved potnye surface, in particular, performed at the ends of these two parts of the rod. Such portions of the rod can be made relatively small in size.Two parts of the rod is made to rotate relative to each other. It also promotes the production capability of the adapter is very small in size, so that it can be entirely placed inside the top node.In a preferred embodiment, the support surface is formed by at least two, preferably four sectors of the circle. The required change of the working length of the valve stem is realized by means of the relative rotation angle of 180 or 90o.The supporting surface may also be made in the form of projections and/or recesses on a flat surface.In the most preferred embodiment, the supporting surface is made symmetric with respect to some point of symmetry. In the transmission bearing forces is carried out symmetrically and without creating undesirable tilting moments.It is also useful to perform one part of the rod with the elongated part in the form of a sleeve, and another run in the form of a cylinder located in the sleeve. The sleeve serves as suprasti rod can be secured against falling out. This precaution provides a full guarantee that the adapter will not be lost.To achieve this, a part of the shaft sleeve is provided outside at least one Cam within the axial guide (groove or groove) in the bottom of the top node is bounded at least on one end.With respect to another part of the stem, it is desirable that the cylinder had an outside at least one Cam, which is the axial groove of the sleeve, limited at least at one end.In addition, in the preferred embodiment, the limitation of the axial guide or axial groove at one end is a ledge made with the possibility of the elastic displacement under the action of the inclined Cam surface. Such a device is useful when the Assembly, after which securely holds all the parts in place.In another improved embodiment, the end position of relative rotation can be fixed by means of locks and/or obstacles. Therefore ensured easy installation of the adapter in the desired position and protection from possible wrong actions. In addition, the mesh may be accompanied by sound.
