Description

известны устройства дл  определени  упрутост  паров (например, нефти и нефтепродуктов ), содержащие наровую и топливную камеры, манометр и систему коммуникаций.Devices are known for determining the vapor elasticity (e.g., oil and oil products) containing a nary and fuel chamber, a pressure gauge and a communication system.

Предложенное устройство отличаетс  от известных тем, что измеритель давлени  в виде гибкого разделител  двух сред расположен на внутренней стороне крышки паровой камеры и св зан с помощью штока с клапаном, выполненным в виде сопла с заслонкой. Это позвол ет новысить точность измерений и расширить их предел.The proposed device differs from the known ones in that a pressure meter in the form of a flexible separator of two media is located on the inside of the lid of the steam chamber and is connected by means of a rod with a valve made in the form of a nozzle with a valve. This allows us to improve the accuracy of measurements and expand their limits.

На фиг. 1 изображено данное устройство; на фиг. 2 - система измерени  давлени .FIG. 1 shows this device; in fig. 2 is a pressure measurement system.

Устройство содержит топливную камеру 1, паровую камеру 2 с верхней разъемной частью 3 и пневматический датчик давлени , состо щий из сопла 4, заслонки 5, штока 6 и сильфона t.The device comprises a fuel chamber 1, a steam chamber 2 with an upper plug part 3 and a pneumatic pressure sensor consisting of a nozzle 4, a damper 5, a rod 6 and a bellows t.

Ст жной болт 8 имеет канал дл  выхода обработанного газа в атмосферу, а все узлы устройства скренлены хомутом 9.The attachment bolt 8 has a channel for the exhaust gas to escape to the atmosphere, and all the components of the device are stitched with a clamp 9.

После загрузки топливной камеры исследуемым продуктом сверху надевают паровую камеру и крышку с измерителем давлени . Все это ст гивают хомутом, и устройство помещают в термостат.After loading the fuel chamber with the test product, a steam chamber and a lid with a pressure gauge are put on top of it. All this is tightened with a yoke, and the device is placed in a thermostat.

Давление измер ют с помощью манометра 10 (фиг. 2), одно колено которого св зано тройником У/ с линией питани  через измерительный дроссель.The pressure is measured using a pressure gauge 10 (Fig. 2), one knee of which is connected by a tee V / s to the power line through a measuring choke.

Предмет изобретени Subject invention

Устройство дл  определени  упругости паров (например, нефти и нефтепродуктов), содержащее топливную и паровую камеры, термостат и измеритель давлени , отличающеес  тем, что, с целью повышени  точности и расширени  пределов измерени , измеритель давлени  выполнен в виде гибкого разделител  двух сред, расположенного на внутренней стороне крышки паровой камеры и св занного с помоп1,ью штока с клапаном, выполненным в вилте сопла с заслонкой.A device for determining the vapor pressure (e.g. oil and oil products) containing a fuel and steam chambers, a thermostat and a pressure gauge, characterized in that, in order to increase accuracy and extend the measurement limits, the pressure gauge is made in the form of a flexible separator of two the inner side of the steam chamber lid and connected with the pump, with a stem with a valve made in the valve nozzle with a flap.
