Definitions

  • the invention relates to an arrangement in connection with an electromechanical actuator, which actuator includes electrical components in a housing, such as a power unit and control electronics, further the transmission mechanism of motion from said power unit to the movable member of the actuator, and in which arrangement a major part of the actuator is placed in a space with a temperature over 120 C.
  • the actuator as per publication FI 954712 is placed with regard to its temperature to quite a normal environment, whereat no cooling is needed. Neither does the actuator produce any heat.
  • the arrangement is suited only for an actuator using compressed air.
  • cooling problems in connection with actuators used in a hot location are solved.
  • the construction of the steam distributing valve can be made short, though a major part of the valve is in a hot steam space and conducts heat out of there to the electric components and bearing members of the valve.
  • the cooling flow can be controllably conducted to the most important, cooling requiring components, e.g. the electric power unit, the motor for instance.
  • the pressure of flow to be conveyed to the housing is regulated and, likewise, the quantity of flow at least by one regulating element that is placed either in the inlet or outlet, the produced cooling effect remains uniform enough.
  • Fig. 1 shows the actuator end with housing and a part of the components in profile.
  • Fig. 2 shows the embodiment of figure 1 viewed from another direction and in profile.
  • Fig. 3 shows a steam valve actuator without housing in profile.
  • FIG 1 there is mounted by means of flange 8 on the steam distribution tube surface a steam valve actuator comprised of body parts 9 and 6.
  • housing 1 On the surface of body part 6 housing 1 is fastened by means of fixing component 2.
  • motor 3 rotating by means of gearing 7 the axle leading to the valve spindle.
  • motor 3 there can also be regulating electronics in the housing to control the valve and an electronic or mechanical thermostat element to adjust the air flow or the pressure.
  • a temperature sensor to measure the temperature or, for instance, a bimetal element for direct adjustment of the flow of cooling air. From the enlarged figure the conduction of the cooling flow through inlet 4 along channels 10 and 11 to the housing can be seen. The flow is let out, for instance, through inlet 5 from the housing,
  • Figure 2 shows the figure 1 embodiment seen from another direction.
  • packing advantageously of heat insulating material, as cork.
  • Figure 3 shows, also included in the housing, a steam valve member, an axle 14 and a valve spindle 13, which is a regu lating and closing member, the motion of which is upward.
  • valve spindle there is a cylinder body, partly open, placed in the steam distributing tube and through the openings of which steam can enter the cylinder and the closing mernber regulate the outlet of steam through the hole in the cylinder bottom.
  • the quantity of flow is determined and the pressure regulated by means of at least one regulating element in connection with the inlet 4 or outlet 5. Regulation is carried out by means of the temperature sensor or the thermostat element in the housing. Most suitably the pressure of the cooling flow is regulated a little higher than the steam pressure in the valve, so that no steam would leak alongside the valve spindle and axle towards the housing. For instance, if the steam pressure is 1 bar, a pressure of 1,5 bar, for instance, is chosen for the cooling flow. As flow medium water or inert shielding gases are used. For instance, in connection with assemblies 4 and 5 the housing can have a pressure relief valve, a shut-off valve, a safety valve and a valve regulating the quantity of flow. By means of the actuator gas or liquid flows, for instance, are regulated.
