Mobile, untill seam A under valve seat and bet air valve body inner stopper B are in contact, now gas injection valve port 3 is opened, such as Fig. 2
It is shown.High pressure steam will enter from gas injection valve port 3 in the solidifying oil reservoir of underground viscous crude, height, in the presence of high-temperature gas, melt underground
Viscous crude, high solidifying oil.
Each gas injection about 15 days or so, in order to further melt viscous crude, high solidifying oil, improves lifting efficiency, it is necessary to vexed
Well week age.Melt underground crude oil due to high temperature, high-pressure gas injection and consume a part of heat and pressure, still there is a level pressure underground
Power.Need to open head valve and start to recover the oil, down-hole pressure is above the ground level measuring station system pressure, and downhole crude can spray automatically
Come, because down-hole pressure is high, the flow rate of liquid of ejection is high, takes sand seriously, does not allow the liquid sprayed to enter in pump chamber, ejection
Liquid flows out from the gas injection valve port 3 on pump.
When down-hole pressure is less than ground metering station system pressure, starts artificial lift liquid, sucker rod drives splined shaft 2
Move up, when the splined shaft jump ring 6 on splined shaft 2 is moved to the through hole of the bottom of valve seat 10, splined shaft jump ring 6 is with being somebody's turn to do
Through hole clamping, so that splined shaft 2 drives gas injection valve 4 to move up by splined shaft jump ring 6, until gas injection valve upper surface D
