Design and modelling of butterfly valves for pipeline systems
Incoming article date: 29.10.2023Pipeline fittings, which include butterfly valves, are not unimportant in pipeline systems. The main function of this design element is to prevent emergencies in pipeline systems. The principle of operation is based on closing of the shut-off device in case of change of direction of the transported medium flow. This ensures reliable flow control and prevents backflow of the medium in the pipeline. The rotary check valve provides reliability, tightness and safe operation of systems, as well as durability with regard to safety requirements. The article deals with the design and calculation of rotary check gates. The purpose of development of such a model range is to create a durable and reliable design, which will be able to ensure during the whole service life a safe operation in production with different parameters of the working environment. To confirm the reliability and serviceability parameters of the design, strength calculation of the butterfly valves has been carried out. As a result of numerical modelling of all designed check gates, the calculated parameters allow to give positive assessment to the gates and confirm compliance with technical requirements.
