Abstract
A novel cage-type sealing pressure valve comprises a valve body, wherein the valve body is composed of an upper valve body and a lower valve body, a spirally wound gasket is installed between the upper valve body and the lower valve body, and the upper valve body and the lower valve body are connected together through a bolt and a nut. A valve rod, a valve plug, a valve cage, a guide valve, another valve rod, packing, an O-shaped seal ring, a packing gland and a seal ring are installed in the valve body, wherein the valve cage is composed of an upper valve cage body and a lower valve cage body. The novel cage-type sealing pressure valve has the advantages of being wide in adjustable range, high in adjustment accuracy and capable of being adapted to the working condition under high differential pressure in the process of use; meanwhile, the valve is reliable in sealing performance, low in gas leakage rate, stable in operation and not prone to vibration.
