Description

Изобретение предназначено преимущественно дл  терморегул торов, управл ющих расходом среды в зависимости от изменени  температуры.The invention is intended primarily for thermostats that control the flow rate of a medium depending on temperature changes.

Известны регулирующие вентили с запорным органом подъемного типа, разгруженным путем выполнени  на нем кольцевой проточки .Known control valves with a locking member of a lifting type, unloaded by performing an annular groove on it.

Недостаток таких вентилей заключаетс  в том, что при малых расходах, когда запорный орган находитс  вблизи седла, он оказываетс  недостаточно разгруженным.A disadvantage of such valves is that at low flow rates, when the valve is located near the seat, it is not sufficiently unloaded.

Предлагаемый регулирующий вентиль отличаетс  От известных тем, что в периферийной части запорного органа, служащей дном кольцевой проточки, выполнены сквозные прорези . Этим достигаетс  улучшение разгрузки, когда запорный орган находитс  вблизи седла , и, как следствие, повышение точности регз пировани  при малых расходах.The proposed control valve differs from the known ones in that in the peripheral part of the closure member, which serves as the bottom of the annular groove, through-slots are made. This results in improved unloading when the valve is located near the saddle, and, as a result, an increase in the accuracy of the flow rate at low flow rates.

На фиг. 1 представлен описываемый вентиль в разрезе; на фиг. 2 и 3 - примеры выполнени  канавки на запорном органе с отверсти ми и прорез ми; на фиг. 4 - запорный орган в закрытом положении; на фиг. 5 - запорный орган при его расположении вблизи седла; на фиг. 6-запорный орган полностью открыт.FIG. 1 shows the described valve in section; in fig. 2 and 3 are examples of a groove on the closure body with holes and slots; in fig. 4 - valve in the closed position; in fig. 5 - shut-off organ at its location near the saddle; in fig. 6-valve body fully open.

Вентиль содержит корпус с входным / и выходным 2 патрубками, между которыми расположено седло 3. В крышке 4 корпуса размещен шток 5, на котором закреплен запорныйThe valve includes a housing with an inlet / outlet and 2 nozzles, between which is located the saddle 3. In the lid 4 of the housing there is a stem 5, on which the stop valve is fixed

орган 6.authority 6.

Канал 7 в штоке 5. камера 8 в крышке 4 и сильфон 9 образуют чувствительное устройство вентил , благодар  которому осуществл етс  уменьшение осевого усили  на все детали.The channel 7 in the rod 5. The chamber 8 in the cover 4 and the bellows 9 form a sensitive valve device, due to which the axial force is reduced on all parts.

Это устройство взаимодействует с внешним толкателем 10. Запорный орган 6 снаби ен направл ющими //, которые скольз т по седлу. В периферийной части запорного органа выполнена кольцева  проточка 12, в дне которой имеютс  отдельные отверсти  13 (фиг. 2) ил сквозные прорези 14 (фиг. 3).This device interacts with the external pusher 10. The locking member 6 is threaded with guides // that slide along the saddle. An annular groove 12 is made in the peripheral part of the closure member, at the bottom of which there are separate holes 13 (Fig. 2) or through slots 14 (Fig. 3).

Предмет изобретени Subject invention

Регзлирующий вентиль с кольцевым седлом и запорным органом подъемного типа, разгруженным путем выполнени  на нем кольцевой проточки, отличающийс  тем, что, с целью улучшени  разгрузки при расположении запорного органа вблизи седла, в периферийной части запорного органа, служащей дном кольцевой проточки, выполнены сквозные прорези.An expansion valve with an annular seat and a lifting-type locking member unloaded by performing an annular groove on it, characterized in that, in order to improve unloading, the locking member is located near the saddle, in the peripheral part of the locking member that serves as the bottom of the annular groove, through slots are made.
