Быстрый закрытие открытие с заблокированным обручем

YY-QGM Type Series quick opening closure with locked hoop quick opening closure with locked hoop is applicable to the openings of pressure pipelines and pressure vessels. The end closure is a kind of mechanical device could be opened and closed quickly. It consists of blind flange, locked hoop, connecting joint, safety interlock system, and opening and closing system.This product absorbed advanced foreign technology and adopted advanced design concepts, clamping and opening system. Compact, flexible, on the basis of ensuring the strength of the product reduced dimensions. When Blind flange locking achieved, there is no relative rotation between the sealing surface and seal ring. So easy to prevent damage of the sealing ring and ensure sealing. The entire opening and closing process can be completed by one person without special tools within two minutes. Thus greatly reducing the labor intensity. This product is especially suitable for pipeline pig launcher and receiver, horizontal filter and the like.Product characteristics Technical parameters:Designed pressure ≤ 42MPaOperation temperature: -40 200 degree Applicable medium: oil, gas, water, chemical raw material Nominal diameter: DN80 DN1500 Structure features: Fast and easy operation, safe and reliable, one person opening/closing in one to two minutes without special tools assistance.
