Abstract

The invention discloses a self-operated type associated gas set-pressure exhaust valve. The valve comprises a valve rod, a valve core, a valve body and a valve cover, the valve rod is connected with the valve core through a fixing pin, the valve core is externally sleeved with a sleeve, the sleeve and the valve core are located above a valve seat, the valve body sleeves outside the valve core withthe valve seat and the sleeve assembled, the valve cover sleeves outside the valve rod and located above the valve body, a swing rod is arranged at the top of the valve cover, the swing rod is fixedon one side of the valve cover through a pin shaft, the swing rod can rotate along the pin shaft, and a pressure adjusting mechanism is arranged on the swing rod. According to the provided self-operated associated gas set-pressure exhaust valve, a distributed cylindrical heavy hammer loading mode is adopted, the pressure of a medium flowing through the interior of the valve is used as an energy source to drive the valve to work automatically, when the fluid pressure reaches a set value, long-time automatic exhaust is achieved, through the distributed cylindrical structure, the opening degree of the valve is controlled through the size of the fluid pressure, then full-opening until emptying is achieved, and the valve is simple in structure and convenient to maintain.

Description

technical field [0001] The invention relates to a valve, in particular to a self-operated sleeve gas fixed discharge valve. Background technique [0002] In the process of oil field development, when the formation energy gradually drops to not enough to maintain self-spraying or self-spraying is possible but the output is too low, or self-spraying cannot be done at the beginning, it is necessary to manually supplement energy for oil recovery, that is, mechanical oil recovery. [0003] Oilfield associated gas is the gas that appears with petroleum liquids between oil layers during the process of oilfield mechanical recovery. The main component is methane, and usually contains a large amount of ethane and other hydrocarbon components. Associated gas recovery treatment refers to the separation of ethane, propane, butane and other hydrocarbon components from gas streams, which can be further processed and sold as pure components or natural gas mixed liquid (NGL) or LPG. Associat...
