Description

one

The invention relates to the field of physics of physics, in particular, to systems for controlling non-spectral quantities,

A known temperature regulator of the heating medium, comprising a body, is bimetallic heat-sensitive; the element, which is made in the form of a partition with holes, divides the housing into two cavities, one of which is connected to the hot coolant supply channel, and the other to the cold coolant supply channel G,

The disadvantage of this coolant regulator is its low speed and low operational reliability.

The aim of the invention is to increase the speed and reliability of the controller.

This is achieved by the fact that, in the heat controller temperature controller proposed, the partition with holes is made of magnetostrictive material, and the body has a control winding connected to the power source through contact groups, the closing contacts of which are located on the rod installed perpendicular 2,

cool to the re-fighter, the output channels are full.

The schematic drawing shows the proposed controller, teplokosi tech-sherature;

The regulator consists of a housing 1, a bimetallic temperature-sensitive element 2, made in the form of a partition wall, dividing the housing into cavities 3 and 4, one of which is connected to the inlet channel | 5 for a hot heat carrier, and the other - from the inlet channel 6 dl Cold. Heat carrier. Bimetallic chuvstvitepnp1 member 2 having openings 7, vsholnenia magnetically tostriktsionnogo material, e.g. netep and iron-based alloy and araoMHHiw, and uiravl pomoschyo with a control coil 8 at zamnsanii contacts 9 or 10, for location with .zhennyh schtoke 11 connected to terkyuchuvstvitelnym element 2 and valves 12 and 13. Output channels 14 and 15 are filled in the upper and lower parts of the cavities for the hot and cold heat transfer fluid, the control shell is connected to the source, and the ions 16.

As an input channel 5, at first, only a hothead simulator is supplied. The sensing element 2, bending, is not aa a rod 11 with valves 12 and 13 fixed on it and contacts 9 and 1О. The element 2 moves until the valve 13 closes the channel 6 for supplying cold coolant and moves further until the contact Y is closed.

In this case, a current from the power source 16 appears in the control winding 8, a magnetic field inside the housing 1 appears and acts on the temperature-sensitive element 2, Last, bending, moving; towards channel 5 with a hot coolant. At this moment, the cold burner is fed to the input of the channel 6, the process of generating pulses of cold and hot heat carriers begins. When the valve moves

Channel 12 with a hot coolant is not closed; the cold coolant fed to the inlet of the channel 6 increases the deformation of the temperature-sensitive element 2, Process; flit until pin 9

not closed In this case, in the control winding 8, the direction of the current is reversed, and the magnetic field, acting on the sensitive element, causes it to bend to the opposite half, opening access to the coolant through channel 5 and closing it

13 channel 6 for cold coolant. Further work process is similar. For

so that the pressure difference does not occur in chambers 3 and 4 in the sensing element 2, they are made out of version 7.

Channels 14 and 15 in cavity Zi 4 increase the speed and reliability of the device, since there is no transfer of cold and hot coolants through the sensing element. If it is necessary to use cold and hot coolants in one pulse channel, the output channels 14 and 15 can be combined outside the device.
