(54) ТЕРМОРЕГУЛЯТОР(54) THERMAL REGULATOR

Изобретение касаетс регулировани. тепловых процессов, в частности регулировани температуры воды в теплсфикачионных системах и установках.The invention relates to regulation. thermal processes, in particular, the regulation of the temperature of water in heating systems and installations.

Известен терморегул тор, содержащий корпус с входной и выходной полост ми и полостью слива, датчик температуры, выполненный в виде сильфонного термобаллона , св занного с узлом настройки,, и регулирующий орган 1.Будучи вклю1|енным в соответствующую систему регул тор работает следующим образом. Дачик температуры, выполненный в виде сильфонного термобаллона, реагиру на ее изменение, перемещает регулирующий орган . Соответствующее изменение заданной величины поддерживаемого параметра в диапазоне регулировани осуществл етс узлом настройки.A thermostat is known, comprising a housing with an inlet and outlet cavities and a drain cavity, a temperature sensor, made in the form of a bellows thermocallon associated with the tuning unit, and the regulator 1. While being included in the corresponding system, the regulator works as follows. Dachik temperature, made in the form of a bellows thermocylinder, reacting to its change, moves the regulator. The corresponding change in the set value of the supported parameter in the adjustment range is made by the tuning node.

Указанный терморегул тор вл етс наиболее близким к изобретению по технической сущности и достигаемому результату . Недостатком его вл етс узкий диапазон регулировани температуры, вследствие чего при работе становитс The specified thermostat is closest to the invention in its technical nature and the result achieved. The disadvantage of it is a narrow range of temperature control, as a result of which it becomes

необходимой последовательна замена терморегул торов с различными диапазонами настройки и, как следствие, необходимость выпуска4 промышленностью больщой номенклатуры терморегул торов и запасных частей к ним,necessary replacement of thermostats with different tuning ranges and, as a consequence, the need for release4 by the industry of a large range of thermostats and spare parts for them,

Целью изобретени вл етс расширение диапазона регулировани терморегул тора .The aim of the invention is to expand the control range of the thermostat.

Указанна цель достигаетс тем, что регулирующий орган терморегул тора состоит из соосных подпружиненных штоков, один из которых, размешенный во входнсй полости, выполнен полым и вл етс плунжером клапана, седло которого размещено в перегородке между выходной полостью и полостью слива, и седлом второго штока , св занного с сильфонным термобаллоном .This goal is achieved by the fact that the regulator of the thermostat consists of coaxial spring-loaded rods, one of which, placed in the inlet cavity, is hollow and is a valve plug, the seat of which is located in the partition between the outlet cavity and the drain cavity, and the second stem seat, associated with a bellows thermopack.

Claims

The thermostat has a housing 1 with an input 2 and an output 3 cavities and a drain cavity 4. The temperature sensor is fuller in the form of a bellows 5, connected to the setting unit 6. The Regulator passes from coaxial spring-loaded rods 7 and 8, the rod 7, placed in the inlet cavity 2, is hollow with a through cavity 9, it is a valve plunger, the seat 10 of which is placed in the partition 11 between the outlet cavity 3 and the drain cavity 4. At the same time, the rod 7 (its end) is the saddle 12 for the rod 8, Saint Zan Koro Thermophone 5. Both rods 7 and 8, respectively, are equipped with springs 13 and 14.. The thermostat works as follows. If the temperature of the water surrounding the bellows bulb 5 corresponds to the setting of the thermostat, then all three cavities — 2, 3, and 4 — are disconnected, since the rod 8 overlaps the through cavity 9 in the rod 7, and the rod 7 touches the saddle 10, separates the output cavity 3 from the drain cavity 4. In this case, intermediate command pressure is fixed in cavity 3. With increasing temperature bellows; bulb 5 lengthens and moves rod 8 and with it rod 7 upward. In this case, the rod 7 moves away from the saddle 10, and the output cavity 3 communicates with the drain cavity 4. The intermediate command pressure in the cavity changes. With a decrease in temperature, the strong background thermal bulb 5 is shortened, and the rods 7 and 8 under the action of the springs 13 and 14 are mixed down, the stem 7, touching the saddle 10, separates the output cavity 3 from the drain cavity 4. Then, with further movement of the stem 8 down, it opens the through cavity 9 in the stem 7, and the input cavity 2 communicates with the output cavity 3. To change the direction of action of the command pressure 911 of the thermostat, it is sufficient to supply the working medium to the corresponding. cavity in the housing (for example, instead of cavity 2, feed into cavity 4). The thermostat is installed in the system in such a way that its bellows 5 is as close as possible to an adjustable flow. Thermal contact of the bellows thermowell 5 with the case of the thermostat 1 to ensure its low inertia should be minimal. Heat insulation pads 15 or other similar devices may be used for this. The proposed thermostat allows regulation in a wide range of temperatures and, moreover, is economically energy efficient, since much less working medium is required for its operation than in known designs. The invention includes a thermostat comprising a housing with an inlet and outlet cavities and a cavity, a drain, a temperature sensor made in the form of a bellows of a thermal bulb connected to a tuning unit, and a regulating member, characterized in that in order to expand the range of thermostat control, the regulator consists of coaxial spring-loaded rods, one of which, placed in the inlet cavity, is hollow and is a valve plunger, the seat of which is placed in the partition between the outlet cavity and the drain cavity a, and the seat of the second stem connected to the bellows germ obalon ohm.
