Abstract
The utility model relates to an alloy two-valve sand-settling device, belonging to the petroleum machines, wherein an upper joint is connected with the screws of an outer tube, the outer tube is connected with the screws of a lower joint, an upper valve cover is connected with the screws of an inner tube, an upper valve ball is arranged in the upper valve cover, an upper valve seat is arranged between the upper valve cover and the inner tube, the inner tube is connected with the screws of the lower joint, and a lower valve ball is arranged in the lower joint. The alloy two-valve sand-settling device is characterized in that a sand-settling tube is connected with the screws of the lower joint and a lower valve seat is arranged between the sand-settling tube and the lower joint. The utility model has the advantages that the alloy two-valve sand-settling device has novel structure, simple installment and use, and has an additional sand-settling tube based on the prior two-valve sand-setting device to prevent sand effectively, and a great quantity of sand will enter into the tail tube, thereby prolonging service life and confirming success oil production for long time.
Description
Technical field
The utility model belongs to petroleum machinery.
Background technology
At present in the oil well of oil exploitation, bottom at oil well pump is connected to double-valve dreg-preventing device, be used for preventing that the sand slag in the oil from entering in the oil well pump, but the anti-slag effect of existing antiresiduum device is limited, the space that is used for depositing slag is little, not long-time sand slag has just been filled, and causes the phenomenon of holddown to take place, and has directly influenced normally carrying out of producing.
Summary of the invention
The utility model provides a kind of alloy double valve sand-settling device, to solve the problem that slag is few, cause holddown of depositing that present double-valve dreg-preventing device exists, the technical scheme that the utility model is taked is: top connection is connected with external pipe thread, this outer tube is threaded with lower contact, last valve cover is connected with Internal Pipe Thread, last valve ball is positioned at the valve cover, last valve seat is between last valve cover and interior pipe, should be threaded with lower contact by interior pipe, following valve ball is positioned at lower contact, sand sediment pipe is threaded with lower contact, and following valve seat is positioned between the boss of sand sediment pipe and lower contact.During use, top connection is connected with oil well pump, and lower contact is connected with tail pipe, during last fuel pump, enter the inlet of oil from lower contact, oil enters down valve from sand sediment pipe then, enters interior pipe again, goes up valve, top connection, enters in the oil well pump then, the sand slag is then because action of gravity enters tail pipe, part sand slag with oil up after, also can fall into outer tube because of the anti-slag effect of last valve.
The utility model advantage is novel structure, and is easy to install, on original double-valve dreg-preventing device basis, increased sand sediment pipe, can better play the sand control effect, a large amount of sand slags sink in the tail pipe, can increase the service life effectively, guarantee that oil extraction operation carries out for a long time smoothly.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Top connection 1 is threaded with outer tube 2, this outer tube is threaded with lower contact 9, last valve cover 3 is threaded with interior pipe 6, last valve ball 4 is positioned at the valve cover, last valve seat 5 is between last valve cover and interior pipe, and pipe is threaded with lower contact in this, and following valve ball 7 is positioned at lower contact, sand sediment pipe 10 is threaded with lower contact, and following valve seat 8 is positioned between the boss of sand sediment pipe and lower contact.
