Embodiment Construction

[0041] The present invention will be further described below in conjunction with accompanying drawing:

[0042] Depend on Figure 1 to Figure 8 As shown, this kind of device that can carry out pressure sampling for various media in the pressure vessel is composed of four parts: an upper cover mechanism, a cylinder body 2, a lower cover mechanism and a sampling mechanism.

[0043] Wherein, the upper cover mechanism is formed by connecting the upper cover 10, the gland 12 and the glass window 11; For sealing, the counterbore in the middle of the upper cover 10 is used for installing the gland 12 and the glass window 11 . The loam cake sealing ring 9 is selected rubber or asbestos material according to container temperature, is used for sealing loam cake and cylinder upper end mating surface. The glass window is a disc-shaped, pressurized quartz glass used to observe the operation of the sampling device. The gland is circular, and it and two sealing rings are used to compress an...

Abstract

The utility model relates to a device capable of sampling various media in a pressure vessel under pressure. The main structure includes four parts: device cylinder, upper cover mechanism, lower cover mechanism, and sampling mechanism. Among them, the device cylinder is the main structure of the sampling device, which is used to install other functional structural components, and the upper cover mechanism is used to seal the body of the device cylinder. The upper part and the lower cover mechanism are used to seal the lower part of the cylinder body of the device, and the sampling mechanism is used to realize sampling of various media in the container. The device can realize the sampling under the condition of the container under pressure, without the need to switch the process flow or stop the production of the container, and can eliminate the safety hazard during sampling; in addition, the device can be used for various media such as gas, oil, water, and sludge in the container Sampling, the type of sampling medium and the sampling volume are not limited; in addition, the lower interface of the device can be matched with the upper manhole flange of the container, and no special modification of the container is required during installation.

Description

technical field [0001] The invention relates to a container medium sampling device, in particular to a device which is installed on the upper part of a pressure vessel and can perform pressure sampling of various media. Background technique [0002] Various storage tanks and other pressure vessels in petroleum and chemical industries require regular medium sampling for laboratory analysis. Most of the media in the container are gas, oil, water and other media. There is still a certain thickness of mixed interface between the two media of oil and water. Under pressure, it is difficult to sample various media at different heights. . At present, the method for carrying out pressure sampling of a pressure vessel is to weld a sampling pipe and install a valve at a corresponding height of the medium in the vessel in advance when the vessel is constructed, so as to realize pressure medium sampling. The disadvantage of this method is that the sampling height of the medium in the c...
