The invention relates to temperature control of the circulating liquids, air or gases, namely a temperature of direct action.Known temperature controllers containing the bulb, for example, patent RF N 2032208, G 05 D 23/02, 1995; RF application N 93029598/09, G 05 D 23/12, 1996; ed. St. USSR N 1654794, G 005 D 23/02, 1991.Closest to the patent can be considered as a temperature controller for paten with the piston, a rod which is connected with the shut-off body. The bulb is filled with temperature-sensitive substance.When the temperature controlled environment of temperature-sensitive substance in the bulb expands and moves the piston rod which acts on the locking body, which reduces the flow rate regulated environment.Setting up such a regulator for maintaining a predetermined temperature associated with considerable difficulties and inconvenience due to the need of access to the stock bulb and shut-off body and the possibility of breaking the seal.In addition, in some cases, the application of the temperature controller at the expiration of the environment through the flow area formed by the shut-off body and the saddle may be a differential pressure between the pressure in the cavity to the valve body and the pressure in the cavity after the shut-off organ. Under the action of differential pressure locking body is moved, the slider becomes insensitive to temperature changes and loses its efficiency.The invention is aimed at creating a temperature controller with high performance.The technical result, which is castignoli his work.To ensure that the regulator is further provided with installed outside the housing of the power cylinder with a piston, a discharge chamber which is communicated with the pressure cavity of the bulb associated with the shut-off body.When you created the conditions for Autonomous configuration management controller to maintain the set temperature by changing the position of the piston rod of the power cylinder located outside of the enclosure, which reduces the complexity of configuration, increases the ease of installation and maintenance. When the power cylinder is set so as to compensate for possible differential pressure environment. The pressure drop in the value of the flow area is not affected. This results in improved reliability and performance of the controller.To ensure that the configuration of the control rod of the power cylinder mechanism has its extension, for example, screw type.According to the point 3 of the claims between the locking body and the stem of the bulb has a damping element such as a bellows. This embodiment prevents damage to the controller when moving the stem of the bulb at temperatures higher than specified. This contributes to the om.In Fig. 1 shows a General view of patentable temperature controller direct action; Fig. 2 - this is the same version it is running.The temperature controller includes a housing 1 with an inlet 2 and outlet 3 channels. In the housing are filled with a temperature sensitive fluid-bulb 4, a stop valve 5 and the seat 6. The bulb has a piston 7, the piston rod 8 which is connected with the shut-off valve 5. Locking the body in the form of glass through Windows 9, which form a seat 6 is the flow area for the environment. Outside of the housing 1 of the regulator has the power cylinder 10 with a piston 11, a stem 12 which has a screw mechanism 13 of his nomination. Discharge chamber of the power cylinder 10 through pipe 14 communicates with the pressure cavity of the bulb 4.In the embodiment, the temperature controller (Fig. 2) stop valve 5 is made conical. Between the locking body and the rod 8 the bulb has a shock-absorbing element is a bellows 15. If necessary, on the rod between the piston 7 and the element 15 may be installed recoil.Works patentable temperature controller as follows.Using a screw mechanism 13 configure the bulb on the under the action of the piston 11, thermo-sensitive liquid is supplied from the power cylinder 10 through line 14 into the discharge cavity of the bulb 4, the piston 7 which is installed in the correct position for the formation of the necessary flow area between the locking body and the saddle 6. The piston 11 of the power cylinder 10 is a permanent position with the controller, while maintaining the same volume of liquid in its pumping cavity.The working medium enters the regulator through the inlet channel 2, then throttled through the flow area between the locking body and the saddle and is discharged through channel 3. With increasing temperature input operating environment temperature-sensitive liquid in the bulb 4 expands and moves the piston 7, the piston rod which acts on the stop body 5, which reduces the flow area and, consequently, to the reduction of the regulated environment.In the embodiment, the temperature controller (Fig. 2) the rod 8 acts on the stop body 5 through the bellows 15. In the case of increasing the temperature controlled environment is higher than the value that is configured controller, the force of the rod 8 the bulb is perceived by the bellows 15, which, warping, prevents breakage in the connection rod 8 and the locking member 5.When reducing the temperature input of the working environment dermocosmetology bore between the locking body and the saddle. The return of the piston 7 is formed under the action of vacuum in the discharge cavity of the bulb.Thus, in the process of temperature control the amount of heat-sensitive liquid in the discharge cavity of the power cylinder 10 remains constant, and in the discharge cavity of the bulb varies with changes in temperature controlled environment.Thanks to the power cylinder for moving the shut-off organ is not affected by the pressure drop. The shut-off organ displacement depends only on the expansion or compression of the heat-sensitive liquid in the discharge cavity of the bulb.Patented temperature control is easy in installation, configuration and operation, high sensitivity, high reliability and efficiency and enhanced functionality.Patent-pending design allows you to use the device as a trap. 1.
