Self-sealing fluid collector

Abstract

The invention provides a self-sealing fluid collector. The self-sealing fluid collector comprises an outer barrel and a core body, the top of the outer barrel is opened for integrally inserting the core body, and an air inlet for fluid to flow in is formed in the bottom end; the core body can be installed in the outer barrel in a pluggable mode and freely rotates with the central axis of the outerbarrel as a rotating shaft, and an air inlet nozzle is installed in the air inlet pipeline in an axial sliding mode, always stretches into the inner bottom of the outer barrel under the action of elastic force and makes extrusion contact with the bottom end of the core body. An air inlet nozzle is inserted into the lower section of a middle hole in an embedded plug in an air inlet in the bottom of the air storage bin, and a sealing plug matched with the conical hole in a bell-and-spigot joint mode is hung above the conical hole and arranged on a guide rod hung in the air inlet pipe in a sleeving and sliding fit mode. The reset spring enables the sealing plug to block the conical hole in the state that the sealing plug is not connected with the air inlet nozzle, and when the air inlet nozzle is connectd, flowing-in fluid is ejected away from the interior of the conical hole. The self-sealing fluid collector is good in maneuverability, high in adaptability and convenient for daily management and use.

Description

technical field [0001] The invention relates to a sampling device, in particular to a self-tight fluid collector. Background technique [0002] In fluid processing, it is usually necessary to sample the fluid. Existing sampling usually uses a syringe or the like to directly extract a certain amount of fluid and bring it into the laboratory for inspection. Although this collection method is simple and the equipment cost is low, but For multi-site or multi-gas source collection, the collector needs to carry multiple sampling equipment, and also needs to be numbered, which is relatively cumbersome in management. Especially for continuous sequential sampling in the same gas source runoff direction, multiple sampling devices are fully Relying on manual management of the collection sequence and labeling the sample type is particularly cumbersome and error-prone. For the detection of some fluids, it is usually a routine inspection, and the operator will carry sampling equipment wit...
