Abstract
The utility model discloses a long-service oil pumping pump valve which is used for prolonging the service life of the oil pumping pump valve and is applicable to an oil exploitation sucker-rod pumping well. The long-service oil pumping pump valve consists of a joint (1-1), a valve cover (1-3), a valve ball (1-4) and a valve seat (1-5), wherein the valve cover (1-3) is internally lined with a soft anti-collision sleeve (1-2) which is wear-resistant and corrosion-resistant; and the anti-collision sleeve (1-2) is capable of absorbing the impact of the valve ball (1-4) so as to protect the valve core (1-3) and further prolong the service life of the oil pumping pump; and the valve cover also can be internally provided with a hard anti-collision sleeve which is wear-resistant and corrosion-resistant, or the valve cover is internally provided with a hard soldering layer which is wear-resistant and corrosion-resistant by surfacing. The problem of breakage of the valve cover can be solved by the three schemes, so that the service life of the oil pumping pump is greatly prolonged.
Description
Affiliated field
The utility model relates to a kind of long lifetime oil pumping pump valve, and it is applicable to the petroleum production oil well, is to be used to prolong the oil well pump valve in working life.
Background technique
The oil pumping pump valve is influence oil well pump pump efficiency and vital part in working life, and valve ball and valve seat are equipped with in its inside, in case appearance damage, whole oil well pump will lose efficacy.In recent years, along with the continuous propelling of the oil recovery degree of depth and the complicated heighten degree of hole condition, because of the oil well pump that the fracture of valve valve bonnet was lost efficacy is on the increase; The main reason of analyzing the valve bonnet fracture is frequently clashed into by valve ball; Because valve bonnet receives the restriction built-in pump valve of pump barrel diameter or oil well internal diameter size outward, cause the valve bonnet wall thin, how many mounting points of oil well pump has certain gradient; Owing to reasons such as crude oil flow poor stabilities; Be not straight up and down usually when causing the valve ball opening and closing, but valve ball one side is opened the sidewall that so just is easy to make the valve ball rotation and clashes into valve bonnet earlier.Valve bonnet is bearing alternate load all the time at work; Receive the frequent impact of valve ball again; Prolongation along with the operating time; Valve bonnet is elongated and clashes into and thin down, and finally causes valve bonnet to rupture suddenly, and the valve bonnet wall is thin, mechanical strength is low, receive alternate load and by several main causes of valve ball bump in be the main reason that causes the valve bonnet fracture by the frequent bump of valve ball.
Summary of the invention:
The purpose of the utility model provides a kind of intensity height, anti-collision, oil pumping of anti abrasive long lifetime pump valve, has solved the problem that valve bonnet is caused valve bonnet to rupture by the frequent bump of valve ball effectively.
The utility model is provided by following scheme:
Scheme one: the utility model is made up of joint, valve bonnet, valve ball, valve seat; Be lined with wear-resistant, corrosion resistant soft crashproof cover in its valve bonnet; Axial and radial clearance are arranged between crashproof cover and valve bonnet and joint; Joint and valve bonnet are through being threaded, and soft crashproof cover is that macromolecular material is processed, and have very excellent elasticity, pliability, physical property and anti-H such as wear-resistant
2S, CO
2Deng chemical stabilities such as acid, salt, integrate anti-eccentric wear and corrosion resistance, and non-scaling, non-wax deposition, can absorb the bump of valve ball, the protection valve bonnet.
Scheme two: the utility model is made up of joint, valve bonnet, valve ball, valve seat; Wear-resistant, a corrosion resistant hard crashproof cover is housed in its valve bonnet, adorns a gasket ring between hard crashproof cover and the joint, gasket ring prevents the axial play of hard crashproof cover; And the sealing between assurance joint and the valve bonnet; Joint and valve bonnet are through being threaded, and hard crashproof cover is processed by wear-resistant, corrosion resistant tungsten-cobalt alloy, and its hardness is higher than valve bonnet and is lower than valve ball; Hard crashproof cover and valve bonnet have radial clearance, can effectively protect valve bonnet to avoid bump.
Scheme three: the utility model is made up of joint, valve bonnet, valve ball, valve seat; Wear-resistant, corrosion-resistant, the shock proof hard solder layer of built-up welding one deck on its valve bonnet internal surface; The point of contact of the length of hard solder layer valve ball and valve bonnet during greater than valve ball to valve bonnet upper dead center, this hard solder layer material is high temperature resistant, and anti-thermal shock is impacted; Antifraying property is good, and combines firmly with valve bonnet.
The utility model reasonable and compact in structure adopts these three kinds of schemes all can solve the valve bonnet breakage problem, can improve the life-span of oil well pump greatly.
