Abstract

The solution concerns the regulation of the heat transfer medium supply to the heating element. The essence is that the control mechanism of the regulation unit of the heat transfer medium supply to the heating element consists of a regulating rod with a protrusion, one end of which rests on the expansion member and the other end rests on the closing member of the throttling element of the heat transfer medium supply to the heating element, and of a tooth rotatably mounted on a pin, while a lever is also rotatably mounted on the pin, resting with its stop on the tooth. The solution can be used especially in the construction industry for regulating the supply of steam to vertical molds in the production of building components.

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to the control of the supply of a heat transfer medium to a heating element. Various devices for regulating the supply of heat transfer medium of the heating element are used at present. Their common disadvantage is the complexity, low resistance to rough handling and, in the case of repairs, the need for specially trained personnel to intervene. In view of the aforementioned drawbacks, it is difficult to provide a coherent control of the supply of the overheating medium to the heater (mold) in rough applications (for example in panel shops).

The essence of the invention is that the control mechanism of the heat transfer fluid supply unit to the heating element consists of a control rod with a protrusion, one end of which is supported by the expansion element and the other end is supported by the closing element of the throttle heat transfer medium to the heating element and a tooth rotatably mounted to the pin, the lever also being pivotally fixed to the tooth by a stop thereof. The advantage of the solution is that, by means of a simple mechanism, it enables automatic control mode to be used to control the flow of the medium to the heating element. There is no need to supply other types of energy (electrical, compressed air). Another advantage is resistance to gross treatment. An exemplary embodiment is shown in FIGS. 1 and 2.

The control rod 2 has a protrusion 2. One end of the control rod 2 rests on a dilatation member and the other end abuts the closure member 9 of the throttle element 10 of the heat carrier 11 into the heating element T1. The tooth 2 is rotatably mounted to the pin 4, and the lever 5, which is supported by its stop on the tooth 2, is also fixed on the pin 4. The sensor 12 has an expansion fluid 14. The sensor 12 is connected to the expansion member by a pipe 13 □ of a heating element. a heat transfer medium is supplied to the body 7. At a constant temperature and with the sensor 12, the volume of the expansion fluid 14 increases, which is transmitted through line 13 to the expansion member. The expansion member gradually elevates the control rod 2 thereto. The protrusion 1 on the control rod 2 pushes the tooth 2 in its turn and then, when the control rod 2 is further lifted, the tooth 2 engages under the protrusion 2 on the control rod 2. In this position, the closure member 9 simultaneously closes the heat transfer device 11. the medium through the throttle element 10 into the heating element 11. In the gradual cooling of the heating body 7, the expansion member 2 will decrease, but the control rod 2 will remain in the upper position suspended by the protrusion 20 of the tooth 2. In order to open the inlet of the heat transfer medium 11 it is necessary to press down the lever 5 which rests on the stop 6 against the tooth 2 rotates (pulls out of engagement with the protrusion 2 of the control rod 2), as a result of which the control rod 2 drops to a lower position (abuts the expansion member 2) while the flow through the throttling element 10 is opened. the supply of steam to the vertical batten molds with the continuous manufacturing process and the wedge switching of the molds, it is expedient to place the lever 2 in the mold 2 when the molds are moved when the wedges are pushed into the lower position. that when the molds are closed, the steam supply is also automatically released. Upon reaching the desired temperature of the manufactured component 15, the steam supply is automatically closed. This ensures that the steam supply to the molds is without human intervention.

If it is necessary that the stop 17 does not strike the lever 2> the lever 5 is turned over and the safety fuse 18 is secured to this position.

If the heat exchanger feed control unit 11 is required to maintain a constant temperature on the heater 7, then the lever 2 is pushed down, whereby the tooth 2 is lifted in this position by the fuse 19 (Fig. 2). This makes it impossible for the tooth 3 and the projection 2 to set into engagement. As the heating element T cools, the control rod 2 and the closure member 9 immediately decrease together with the expansion element 8, and as a result, the intake medium 1 is immediately opened to the heating element 7 and its temperature is stabilized.

The solution according to the invention can be used; especially in the construction industry when regulating the steam supply to vertical molds in the manufacture of building components.
