ABSTRACT

The article is devoted to the choice of material for the sealing element of the gate assembly of gate valves. Two new composite materials have been proposed as a material for the sealing element of the valves. Where the following are selected as the matrix: butadiene-nitrile rubber of the brand SKN-26 and fluoroplast of the brand FT4. It is shown that both composite materials can be used to manufacture sealing elements for high-pressure valves. At the same time, samples from the composition with a fluoroplast matrix show the best resistance to chemical influences. It was also found that the factor of nanoparticles in the composite material contributes to the formation of a stable structure with increased physical and mechanical characteristics.

Keywords: gate valve, sealing element, gate, synthetic butadiene-nitrile rubber mixture, composite material.
