High-viscosity material sampling structure and method

Abstract

The invention discloses a high-viscosity material sampling structure, which comprises a ball valve body, a ball valve core and a control structure, wherein the ball valve body is arranged on the high-viscosity material conveying pipeline; the ball valve core is matched with an inner cavity of the ball valve body; the ball valve core is rotationally matched in the ball valve body; the control structure is in transmission connection with the ball valve core; the ball valve body is provided with a medium inlet and a medium outlet; a medium flow channel with the two ends penetrating through the ball valve core is formed in the ball valve core;the ball valve body is further provided with a sampling opening and a pushing and pressing device; the sampling port is arranged between the medium inletand the medium outlet; a valve is arranged at the sampling port; the pushing and pressing device is arranged opposite to the sampling port; a pressure relief space is arranged between the ball valvebody and the valve and / or between the ball valve body and the pushing and pressing device, and the valve and / or the pushing and pressing device are / is communicated with an inner cavity of the ball valve body through the corresponding pressure relief space. The invention further discloses a sampling method adopting the high-viscosity material sampling structure. According to the high-viscosity material sampling structure and method, sampling is safe and efficient, and coagulation and blockage are not likely to happen.

Description

technical field [0001] The invention relates to the technical field of pipeline sampling, in particular to a high-viscosity material sampling structure and method. Background technique [0002] In the daily production process, it is often necessary to take samples to test the materials conveyed in the pipeline. For the transportation of high-viscosity materials, it is necessary to rely on the flow rate brought by the high pressure difference and the high material temperature. During the sampling operation, there are two risks from high pressure and high temperature. High-temperature and high-pressure high-viscosity materials are prone to splashing and scalding. Moreover, the traditional sampler pipeline has a small diameter and is prone to condensation and blockage. Contents of the invention [0003] The invention aims to provide a high-viscosity material sampling structure and method, which is safe and efficient in sampling, and is not prone to condensation and blockage....
