Problems solved by technology

For high-temperature butterfly valves with such a structure, since the sealing ring gland is not fixed, the ground sealing ring is likely to be misaligned along the circumferential direction during the installation process, so that the ground sealing ring cannot form a good seal with the valve disc, resulting in valve failure. Leakage, which in turn caused unnecessary downtime maintenance of industrial oxygen generators, affected the operation stability of industrial oxygen generators, and also increased the labor intensity of maintenance workers

Abstract

The invention discloses a high-temperature butterfly valve comprising a valve body, a valve clack, a seal ring, and seal ring cover. The valve clack is arranged in the valve body. The seal ring is arranged between the valve body and the valve clack. The valve body is further provided with the seal ring cover used for press the seal ring. A fastener is arranged on the lower portion of the seal ring cover. A groove matched with the fastener is formed in the valve body. The fastener and the groove are matched to have the seal ring cover fixed. By the arrangement, the well-ground seal ring is less prone to dislocation along the circumferential direction during mounting, so that good sealing effect can be achieved between the well-ground seal ring and the valve clack to prevent valve leakage and unnecessary maintenance downtime of an industrial oxygen generator, operational stability of the industrial oxygen generator is guaranteed, and meanwhile, labor intensity of maintenance workers is reduced.

Description

technical field [0001] The invention relates to a high-temperature butterfly valve, in particular to a high-temperature butterfly valve used in an industrial oxygen generator, and belongs to the technical field of valves. Background technique [0002] The principle of the industrial oxygen generator is to use the air separation technology, first compress the air with high density and then use the difference in the condensation point of each component in the air to separate the gas and liquid at a certain temperature, and then further rectify it. The industrial oxygen concentrator is filled with molecular sieves, which can absorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and purified to become high-purity oxygen. At the same time, the industrial oxygen generator is equipped with a high-temperature butterfly valve used in conjunction with molecular sieves. The structure is as attached figure 1 As shown, it includes valve body 1, va...
