description 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 th
