Abstract
A sucker-rod oil-well pump cylindrical pump valve is an oilfield oil extraction device, comprising parts including a valve cover, an adjusting space, a columniform valve, a sands setting space, a valve seat and a press cap, etc., all of which are connected with one another. With the technology, pump efficiency is increased by 40 percent in production, and pump inspection period is prolonged by 60 days.
Description
One, technical field: the utility model relates to the cylindrical pump valve of a kind of oil field extracting device of oil, especially rod pumping pump.
Two, background technique: rod pumping pump belongs to the main production equipments of oil well, its pump valve adopts ball valve usually, working environment is in high temperature, high pressure, high-alkali, contain in corrosive gas stream, the working condition of valve is directly connected to the pump efficiency and the pump detection period of pump, mainly there is following problem at work: the fluid in process of production pump efficiency that reduced of valve ball, bump valve cover and valve seat when rising and falling, cause the damage on valve ball surface, liquid produces anti-top power to the valve body during falling, has reduced the degree of filling of pump; When containing impurity such as reservoir sand in the crude oil, reduced the sealing of valve ball, thereby reduced pump efficiency; The pump of different model all adopts the pump valve of same size and structure can't improve pump efficiency.
Three, summary of the invention: the purpose of this invention is to provide the cylindrical pump valve of rod pumping pump, it has overcome the deficiency in above original technology, it is mainly by the valve cover, adjust parts such as space, cylindrical valve, sand setting space, valve seat, pressure cap and be formed by connecting, the valve cover comprised oily plate washer and valve plate washer; Cylindrical valve lower end is a cone; Valve cover and pressure cap screwed connection, there is valve seat the top of pressure cap; It is indoor that cylindrical valve is positioned at the valve that valve cover and valve seat constituted, and is provided with at the crown center of garden cylindricality valve and adjusts the space, and the blending space is a cylindrical cavity; The sand setting space is set being positioned at cylindrical valve cone and valve seat contact position.
When work, the valve cover can make the pressure of pump fluid column all act on the valve, and valve is fallen after rise fast, eliminated the anti-top power of liquid to valve, to clash into end face simultaneously and separate, realize double-layer seal with seal face, by the sand setting space improved valve with between sealing; Adjust the space and can adjust the weight of valve, shortened the stroke up and down of valve, help valve and fall after rise, reduced the impact damage probability according to different pump type needs.
Owing to adopt such scheme, can improve pump efficiency 40% aborning; Prolong pump detection period 60 days.
Four, description of drawings: accompanying drawing is the structural representation of the cylindrical pump valve of rod pumping pump:
Among the figure 1, valve cover 2, adjust space 3, cylindrical valve 4, sand setting space 5, valve seat 6, pressure cap
Five, embodiment: in above accompanying drawing, valve cover 1 and pressure cap 6 are used screwed connection, and there is valve seat 5 top of pressure cap 6; It is indoor that cylindrical valve 3 is positioned at the valve that valve cover 1 and valve seat 5 constituted, and is provided with at the crown center of cylindrical valve 3 and adjusts space 2; In cone that is positioned at cylindrical valve 3 and valve seat 5 contact position sand setting space 4 is set.
