Abstract

The invention provides a self-spraying throttle valve. The self-spraying throttle valve comprises a bottom mounting flange and a spraying valve body, wherein the bottom of the bottom mounting flange is fixedly connected with a first connecting port; an anti-sliding thread is arranged on the side surface of the first connecting port; a threaded hole is formed in the upper surface of the bottom mounting flange; a plurality of groups of first mounting holes are formed in the upper surface of the bottom mounting flange and positioned on the outer side of the threaded hole; the outer side surface of the spraying valve body is fixedly connected with a mounting seat; a second mounting hole is formed in the upper surface of the mounting seat; the bottom of the spraying valve body is fixedly connected with a threaded connecting port; and the top of the spraying valve body is fixedly connected with a cylindrical oil spraying port. According to the self-spraying throttle valve, the bottom mounting flange structure is arranged, so that the spraying valve body can be conveniently mounted, the mounting seat structure arranged on the spraying valve body can be reinforced by adopting a bolt, and the installation and the use are very convenient.

Description

technical field [0001] The invention relates to the technical field of throttle valves, in particular to a self-spray throttle valve structure. Background technique [0002] 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 continuously lift it from the bottom of the well to the ground. Such a production well is called a self-flowing well. The method of oil recovery is called self-injection oil recovery, but in order to recover all the light oil or condensed oil (substances with low carbon atoms) when spraying out, it is necessary to use the aperture control of the non-replaceable valve that controls self-injection throttling. within 1 / 3 of the main via hole diameter. [0003] The traditional self-spray throttle valve does not have the function of adjusting the size of the spray valve, and cannot protect itself when the pressure in the well is too high, which will cause danger and loss of valuable cond...
