| 发明名称 | Thermo-hydraulically actuated process control valve | ||
| 摘要 | A thermo-hydraulically actuated valve including a housing; a closure member capable of preventing and permitting fluid flow through the housing. An actuation fluid chamber disposed at the housing and sealed from an external environment. A motive force transmitter in force transmissive communication with the closure member. The transmitter being in fluid communication with the actuation fluid chamber; and a heating element in thermal communication with the actuation fluid chamber. The valve being devoid of a dynamic seal between an area of the valve to be contacted by a managed fluid within the valve and an environment outside of the valve. | ||

| 主权项 | 1. A thermo-hydraulically actuated valve comprising: a housing; a closure member capable of preventing and permitting fluid flow through the housing; an actuation fluid chamber disposed at the housing and sealed from an external environment, the actuation fluid chamber including a fluid connection to a dump chamber; a motive force transmitter in force transmissive communication with the closure member, the transmitter being in fluid communication with the actuation fluid chamber; and a heating element in thermal communication with the actuation fluid chamber, wherein an area of the valve to be contacted by a managed fluid within the valve is devoid of a dynamic seal in contact with an environment outside of the valve, and wherein, at a pressure threshold of actuation fluid in the actuation fluid chamber, the dump chamber is configured to open to allow rapid depressurization of the actuation fluid chamber. | ||
