Изобретение относитс  к области турбомашиностроени  и касаетс  конструкции уплотнений турбомашины.The invention relates to the field of turbomachinery and concerns the design of the turbomachine seals.

Известно уплотнение вала, содержащее корпус с гидрозатворной камерой, в которой размещены плавающие кольца 1.Known shaft seal, comprising a housing with a sealing chamber, in which floating rings 1 are placed.

Недостатком такого уплотнени   вл етс  повышенный расход затворной жидкости в сторону уплотн емой полости.The disadvantage of such a seal is the increased flow rate of the barrier fluid towards the sealed cavity.

Наиболее близким по технической сущности  вл етс  уплотнение вала Турбомашины , содержащее корпус с гидрозатворной камерой, подключенной к линии подачи затворной жидкости, и установленные в камере с зазором относительно вала плавающие кольца, отдел ющие камеру от газовой полости турбомащины с одной стороны и от атмосферы с другой 2l .The closest to the technical essence is the Turbomachine shaft seal, comprising a housing with a hydraulic lock chamber connected to the supply line for the barrier fluid, and floating rings in the gap chamber relative to the shaft separating the chamber from the gas cavity of the turbo-belt on the one hand and from the atmosphere on the other. 2l.

Недостатком такого уплотнени   вл етс  возможность прорыва газа в атмосферу , что недопустимо при работе с токсичными или взрывоопасными газами.The disadvantage of such a seal is the possibility of gas breakthrough into the atmosphere, which is unacceptable when working with toxic or explosive gases.

Целью изобретени   вл етс  предотвращение прорыва газа в атмосферу.The aim of the invention is to prevent gas from escaping into the atmosphere.

Поставленна  цель достигаетс  тем, что в камере установлен емкостный датчик наличи  газа в затворной жидкости, а в кольце со стороны газовой полости выполнен кольцевой канал, подключенный к линии подачи затворной жидкости при ПОМОЩ1 клапана, св занного с датчиком через усилитель и исполнительный механизм .The goal is achieved by the fact that a capacitive gas presence sensor in the barrier fluid is installed in the chamber, and in the ring from the gas cavity there is an annular channel connected to the supply line of the barrier fluid through the valve HELP associated with the sensor through an amplifier and an actuator.

На фиг. 1 показано уплотнение и схема включени  датчика, продольный разрез; на фиг. 2 - датчик, разрез.FIG. Figure 1 shows the seal and sensor wiring diagram, longitudinal section; in fig. 2 - gauge, cut.

Уплотнение содержит корпус 1 с гидрозатворной камерой 2, в которой с зазором относительно вала 3 размещены плавающие кольца 4 со стороны газовой полости мащины и кольца 5 - со стороны атмосферы.The seal includes a housing 1 with a water seal chamber 2, in which with a gap relative to the shaft 3 floating rings 4 are placed on the gas cavity side of the maschine and ring 5 on the atmosphere side.

Камера 2 подключена к линии 6 подачи затворной жидкости. В камере 2, в частности внутри кольца 5, установлен датчик 7 наличи  газа в затворной жидкости , подключенный через усилитель 8 и исполнительный механизм 9 к клапану 10, установленному на линии 11 подводаChamber 2 is connected to the barrier fluid supply line 6. In the chamber 2, in particular inside the ring 5, a sensor 7 for the presence of gas in the barrier fluid is mounted, connected through an amplifier 8 and an actuator 9 to a valve 10 installed on the supply line 11
