Description

A self-spraying throttle valve

technical field

The invention relates to the technical field of throttle valves, in particular to a self-spraying throttle valve structure.

Background technique

If the oil layer has enough energy, it can not only drive crude oil from the oil layer to the bottom of the well, but also can continuously lift it from the bottom of the well to the surface. Such production wells are called self-blowing wells. It is called self-injection oil extraction, but in order to recover all the light oil or condensed oil (substances with low-carbon atoms) when it is used for ejection, it is necessary to use the aperture control of the replacement-free valve that controls the self-injection throttling. Within 1/3 of the main through hole diameter.

The traditional self-spray choke valve does not have the function of adjusting the size of the spray valve. When the pressure in the well is too large, it cannot protect itself, which will lead to dangerous loss of valuable condensate oil, and it is not easy to install and use.
