Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
In the present invention, the use of directional terms such as "upper, lower, left and right" in the absence of a contrary explanation generally refers to the orientation shown in the drawings. "inner and outer" refer to the inner and outer contours of the respective component itself.
The utility model provides a connect sampling device, including sample portion 1, with the jar body connecting portion 2 that the discharge opening of the jar body matches and the discharge tube connecting portion 3 that matches with the discharge tube, jar body connecting portion 2 and discharge tube connecting portion 3 pass through sample portion 1 communicates each other.
Through this technical scheme, when needs are to the inside liquid sample of tank, with the discharge opening intercommunication of this jar body connecting portion 2 and the tank wagon that connects sampling device to with discharge tube connecting portion 3 and discharge tube intercommunication, the discharge opening of the jar body is indirect with discharge tube UNICOM, and jar body connecting portion 2 and discharge tube connecting portion 3 can include if suitable and discharge opening and discharge tube sealing connection's such as flange component. The sampling portion 1 comprises a closable tubular portion which can be inserted into a sampling device such as a sampling bottle. When beginning unloading, the internal liquid of jar flows into this joint sampling device through the discharge opening to through discharge tube inflow preset position, the inside three-way pipe that forms of this joint sampling device, the internal liquid of jar of in-process of unloading can flow into sampling portion 1, and introduce the sampling bottle with partly liquid through the tubulose portion of sampling portion 1, in order to reach the purpose of sample.
The utility model discloses in, jar body connecting portion 2 with discharge tube connecting portion 3 is located respectively the both ends of sample portion 1. Through this technical scheme, be convenient for this connect sampling device respectively with jar body discharge opening and discharge tube connected to the setting of sample portion 1 conveniently draws forth tubulose portion and operates it in this connect sampling device's middle part.
The utility model discloses in, sample portion 1 is including the intercommunication jar body connecting portion 2 with the main part of discharge tube connecting portion 3 and follow the sampling tube 4 that the main part extends, sampling tube 4 is provided with opening and closing piece 5. Through this technical scheme, when sampling operation, operating personnel opens the discharge valve door of the jar body after, can control the outflow and the stop of the liquid of sampling tube 4 through the switching of control on-off piece 5 to the convenience is taken a sample many times to liquid. Wherein, the opening and closing piece 5 can be a ball valve, a gate valve and the like.
In order to avoid excessive liquid in the tank body flowing into the sampling tube 4 during sampling operation, so that the liquid is sprayed out of the sampling tube 4 when the opening and closing piece 5 is opened, in the technical scheme, the tank body connecting part 2, the discharging tube connecting part 3 and the main body part are all in a revolving body structure and the revolving center lines are overlapped. Through this technical scheme, when unloading, jar internal liquid can be followed jar body connecting portion 2 to the unobstructed flow of discharge tube connecting portion 3, and most liquid can directly flow in the discharge tube, and little part liquid can flow in sampling tube 4, is convenient for control the flow of sampling tube 4
