초록 ▼

A compact manifold ball valve having a valve body defining a valve chamber and having first and second ends and a first flow passage intersecting the valve chamber a cylindrical sealing surface defining a bonnet and valve stem passage also intersecting the valve chamber. A seat and ball retainer is

A compact manifold ball valve having a valve body defining a valve chamber and having first and second ends and a first flow passage intersecting the valve chamber a cylindrical sealing surface defining a bonnet and valve stem passage also intersecting the valve chamber. A seat and ball retainer is threaded into the second end of the valve body and provides for support and positioning of a pair of trunnion support elements and a pair of seat assemblies. A valve ball having opposed trunnions is rotatable between open and closed positions within the valve chamber and is supported by the trunnion supports. A valve stem and bonnet assembly is secured and sealed to said valve body and is actuated to rotate the valve ball for opening and closing thereof. The valve seats are capable of metal-to-metal sealing with the valve ball in the event of heat destruction of said face seals to provide the valve with a fire-safe character. The seats incorporate high temperature graphite filament seals for fire-safe sealing between the valve seats and valve body in the event of heat destruction of said back seals. Other internal metal surfaces are arranged for metal-to-metal fire-safe sealing in the event the primary seals are destroyed by heat.

The system of claim 11, wherein said fluid-motion-powered modulated reflector further comprises a frequency selector to control the speed of rotation of said chopping wheel such that the radiation signal is modulated by said chopping wheel in accordance with the speed of rotation of said chopping wheel. 15. The system of claim 11, comprising a plurality of fluid-motion-powered modulated reflectors. 16. The system of claim 15, wherein said frequency selector of each fluid-motion-powered modulated reflector controls the speed of rotation of said chopping wheel such that the radiation signal is modulated by said chopping wheel in accordance with the speed of rotation of said chopping wheel. 17. The system of claim 15, wherein said reflectors are positioned in a predetermined array and predisposed in a direction to reflect the radiation signals. 18. The system of claim 17, wherein each frequency selector controls the speed of rotation of said chopping wheel such that the radiation signal is modulated by said chopping wheel in accordance with the speed of rotation of said chopping wheel to be predetermined and different from any other reflected radiation signal modulated in said array. 19.
