Embodiment Construction

[0035] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] like Figure 1-Figure 2 As shown, the forced closing suction valve 100 provided in this embodiment includes: a first valve cover 200, a first return spring 300, a first valve ball 400 and a first valve seat 500; the first valve seat 500 is arranged on the second Inside a valve cover 200, abuts against one end of the first valve cover 200, and forms a first accommodating space between the first valve seat 500 and the first valve cover 200, the first return spring 300 and the first valve ball 400 are all located in...

Abstract

The invention provides a forced closing suction valve and an inclined shaft oil well pump and relates to the technical field of oil exploitation equipment. The forced closing suction valve comprises a first valve cover, a first return spring, a first valve ball and a first valve seat. A forced resetting structure without a pin shaft is adopted, and the first valve ball can be in abut joint with a valve ball limiting step or the first valve seat; the valve ball limiting step is used for accommodating the first valve ball, the step surface is used to limit the jump height of the first valve ball, the first valve ball has a righting effect and the limit position is reliable; and the first return spring has elastic tendency to make the first valve ball being close to the first valve seat. The first return spring does not cause excessive skew when the upper and lower compression movement is performed, and the outer ring of the first return spring is not damaged due to wear, so that the failure of the rubbing off can be effectively avoided, the problem that a valve pair in an inclined shaft oil well pump is not easily closed can be well solved, the pumping efficiency of the inclined shaft oil well pump can be greatly improved, the liquid production capacity of an oil well can be increased, and the overall working life can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of oil exploitation equipment, in particular to a forced closing suction valve and an oil pump for an inclined well. Background technique [0002] In recent years, with the increasing difficulty of oil well mining, the application of inclined wells and highly inclined wells has increased, and the demand for oil pumps for inclined wells and deep wells has also increased. [0003] The forced valve inside the inclined well oil pump in the prior art usually adopts the structure of a movable pin shaft and a spring for forced reset in the pin shaft hole. [0004] However, in the forced valve of the inclined well oil well pump in the prior art, the pin shaft and the pin shaft hole are easy to wear and become larger and lose the limit function, thereby causing the return spring to be compressed and broken, making the service life of the forced valve short , The situation that the forced valve fails in a short perio...
