Description
Technical field
The utility model belongs to the Sampling techniques of liquid medium, mainly proposes a kind of harmful liquid closed formula sampling thief.
Background technology
There is following shortcoming in the Liquid sampler that present home market petrochemical industry is adopted: 1, sample lines complexity, sampling valve is too much, causes system comparatively huge.2, because the pipeline tie point is more, cause the trouble spot many, easily produce the leakage of inflammable hazardous medium, thus the security incident of causing, occupational illness and environmental disruption; 3, sampling technology falls behind, and can not directly mate with advanced person's sampling analysis experimental facilities, makes in the sample transfer process and produces secondary pollution, causes check data can not reflect on-the-spot truth, influences the assay result; 4, the sampling apparatus design is unreasonable, makes complicated operating process, easily causes maloperation.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of harmful liquid closed formula sampling thief, make it reliably airtight in sampling process, and the sample that obtains of will sampling directly sends in the sample receiver, do not produce unnecessary secondary and divides the sample operation, guarantees the true and reliable of analytic sample.
The utility model takes following technical proposals to finish its invention task: a kind of harmful liquid closed formula sampling thief, and it mainly includes sample conversion valve, cutting ferrule pipe adapter and is communicated with base, sample receiver sheath; The sample conversion valve has three valve ports, promptly has the band that is communicated with pressure pipeline and presses the sampling media inlet, presses sampling media to enter in the sample conversion valve in order to make band when opening; Have the liquid medium loop exit with the medium circulation pipeline connection, press sampling media to flow out, be used for replacing the stale sample media of former pipeline by the medium circulation outlet in order to when opening, to make band; Has the liquid sample media outlet that is communicated with cutting ferrule pipe adapter center pit, in order to when opening, to make sampling media enter the cutting ferrule pipe adapter; The cutting ferrule pipe adapter is connected its other end thread connection and is communicated with base and is provided with sealing gasket at point of attachment with the sample conversion valve, be communicated with the sample introduction pin hole seat that has the inlet opening that is communicated with cutting ferrule pipe adapter center pit and be communicated with inlet opening in the base, sample introduction pin hole seat is provided with sample introduction needle; Be communicated with in the base to be provided with exhaust needle and to make exhaust needle draw interface and communicate with the exhaust on the connection base pedestal by exhaust pin hole seat; Being communicated with base links by sample pin clamping pad and sample receiver sheath, and the injection port that makes sample receiver and sample introduction needle, exhaust needle are corresponding, so that when inserting sample receiver on the container sheath, sample introduction needle and exhaust needle can pierce through container silica gel lid and enter in the container, the analytical sample that is obtained by sampling is directly entered in the sample receiver, and make whole process keep air-tight state.
Have the scavenging duct interface that is communicated with its center pit on the cutting ferrule pipe adapter, it is a female thread structure, in order to be connected with nitrogen or pressurized air pipeline is purged.
The utility model reasonable in design, the physical characteristics of medium can reach temperature≤400 ℃, pressure 0.2～20Mpa, can be widely used in the sampling of the danger medium such as various harmful, poisonous, inflammable, explosive in the petrochemical industry, its whole sampling is carried out in air-tight state, and the analytical sample that can make acquisition directly enters in the sample receiver, do not produce unnecessary secondary and divides the sample operation, guaranteed the true and reliable of analytic sample.
Description of drawings
