Problems solved by technology
But the existing structure has the following deficiencies: 1. In the sealing assembly of the sample feeding rod, the sealing ring is often installed on the top of the lower sealing rod and between the bottom of the upper sealing seat and the top of the lower sealing rod. When the seat is separated, the dust generated by the combustion tube in the test tube will fall on the surface of the sealing ring and the lower sealing rod, and the dust accumulation formed after long-term use will affect the sealing effect and test accuracy; 2. The " "Alignment" cannot be adjusted automatically, and misalignment is prone to affect the sealing effect during the process of feeding and discharging samples

The invention discloses a sealing component for a sampling mechanism of an infrared hydrocarbon meter. The sealing component comprises an upper sealing seat, a lower sealing rod, a lower sealing seat and a lifting plate component, wherein the lifting plate component is positioned below the sealing rod; the top of the lower sealing rod is sleeved inside the upper sealing seat; the bottom of the lower sealing rod is sleeved inside the lower sealing seat; and a sealing ring is arranged between the external side face of the lower sealing rod and the inner wall of the upper sealing seat. The sealing component for the sampling mechanism of the infrared hydrocarbon meter has the advantages of simple and compact structure, low cost, convenient mounting and capability of improving the whole testing precision and prolonging the service life of sealing ring.
Description
technical field [0001] The invention mainly relates to the field of element analysis equipment, in particular to an infrared hydrocarbon meter. Background technique [0002] With the continuous advancement of science and technology, in order to reduce labor intensity and improve work efficiency, more and more equipment is developing towards automation. The existing infrared hydrocarbon meter generally uses an automatic sample feeding mechanism to operate the test sample. Under the operation of the driving device, the sample feeding rod is adjusted in the horizontal position, and then the sample to be tested is sent into the furnace through the lifting movement. body. But the existing structure has the following deficiencies: 1. In the sealing assembly of the sample feeding rod, the sealing ring is often installed on the top of the lower sealing rod and between the bottom of the upper sealing seat and the top of the lower sealing rod. When the seat is separated, the dust ge...
