Abstract

The invention discloses a sampling valve for chemical pipeline medium sampling, and belongs to the technical field of valves. The sampling valve comprises a valve body, a valve cover, a valve core ball and a valve rod, the valve body and the valve cover are fixedly connected to form a valve cavity, the valve cavity is in dynamic seal fit with the outer surface of the valve core ball, the lower endof the valve rod is fixedly connected with the valve core ball, and the upper end of the valve rod is connected with a handle; and the sampling valve is characterized in that the valve core ball is of a solid ball body structure, a sampling opening is formed in one side of the valve core ball, the rotation angle of the handle is set to be 180 degrees, when the handle is located at two extreme positions, the sampling opening is aligned with fluid channels of the valve body and the valve cover respectively, and the port of the valve cover is connected with a sampling bottle. The valve element can effectively rotate by 180 degrees, it is guaranteed that liquid obtained from the sampling opening is conveyed out of the valve body after the valve element is rotated by 180 degrees, the samplingefficiency of the spherical valve is improved, the volume of the sampled liquid is guaranteed, and waste of raw material is avoided.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a sampling valve used for sampling chemical pipeline media. Background technique [0002] The sampling valve is installed on the medium conveying pipeline to conduct online sampling of the medium passing through the pipeline, and then to detect and test the sample taken. The working conditions of the sampling medium include special medium working conditions such as high temperature, high pressure, corrosive, volatile, toxic and harmful. Whether the sampling point can be sampled normally will directly affect the quality control and safe production of the product. Moreover, there are many types of sampling valve structures. According to different working principles or performances during sampling, sampling valves are mainly divided into three types, including double-opening valves, flange clip valves, and sampling valves with insulation jackets. [0003] Since the sampling valve m...
