Analysis of the fire-resistant structure of the valve seat in pipeline ball valves: To meet the growing demand for oil and natural gas in our country, thousands of kilometers of large-scale transmission pipelines will be constructed each year in the coming period, along with various oil and gas storage and transportation facilities such as pressure boosting stations, distribution stations, and large-scale storage facilities. Due to the flammable and explosive nature of oil and gas, very strict quality requirements are imposed on large-scale oil and gas storage and transportation projects. For the ball valves used in such projects, in addition to meeting the requirements of API6D standards, valve manufacturers are also required to provide third-party fire protection certification to ensure that the structure of the valves is safe and fire-resistant. Purpose of the fire-resistant structure design for valve seats, Design of fire-resistant structures for valve seats, Analysis of reasons for leakage after a fire in valve seats, Principles of the fire-resistant structure design for valve seats – Typical fire-resistant structures for valve seats, Drawings of fire-resistant ball valves for pipelines
The materials are average; there’s nothing novel about them, just some conventional structures. . .
It is difficult to see significant changes in valve design at present; more focus is placed on material selection and control of production quality
With your design, it’s obvious that the valve seat uses an O-ring for sealing. It’s not a fire-resistant structure at all.
