Closed-cup flash point instrument

Abstract

The invention discloses a closed-cup flash point instrument. The closed-cup flash point instrument comprises a horizontal working plane, a vertical working plane, a machine head, a lifting table, a sweeping slide way, a fixing ring, a flash point protection ring, an instrument box, an oil cup opening, an ignition cover fixing hole, a bolt and connecting holes, wherein the horizontal working plane is perpendicular to the vertical working plane; the instrument box is provided with a workbench, and is fixedly arranged on the workbench via the bolt; the horizontal working plane is provided with the oil cup opening which is provided with the flash point protection ring; the flash point protection ring is provided with the fixing ring; the lifting table is arranged at one side of the workbench on the instrument box; one end of the lifting table is fixedly arranged on the instrument box, and the other end surface is provided with the connecting holes. The closed-cup flash point instrument is simple in structure; the opened-cup mode and the closed-cup mode are convenient to switch, and are high in universality; the production and detection costs are reduced; the closed-cup flash point instrument is high in output signal, flexibility and anti-interference capability, and cannot generate leakage detection and misinformation.

Description

technical field [0001] The invention relates to the technical field of testing instruments for petrochemical products, in particular to a closed flash point instrument. Background technique [0002] The flash point tester is an important testing instrument for petrochemical products. It is generally divided into a closed flash point tester and an open flash point tester. The traditional design scheme is that the closed flash point tester and the open flash point tester have a self-contained structure. The two instruments do not have a common The increase in the types of instruments increases the cost of materials and inventory during production and application. Since the detection circuit works under high pressure, high requirements are placed on the instruments used, and the interference generated is also large. The thermocouple detection method is very Simple, low cost, the existing flash point meter has small output and low sensitivity, which is very easy to produce misse...
