Abstract
The utility model provides a cover single current valve is not had in water injection well slant, includes: casing (1), plug (2), valve ball (3), blind (4), disk seat (5), characterized by: personally experience sth. Part of the body for " Y " type that the drum constitutes cover single current valve is not had in water injection well slant casing (1), and the upper portion of lower extreme import (J) is equipped with disk seat (5), and the upper portion of disk seat (5) is equipped with valve ball (3), and the upper portion of casing (1) is equipped with the internal thread hole, has plug (2) on the interior threaded hole, and the left end of casing (1) is equipped with export (C), and the left end of export (C) is equipped with blind (4). The utility model is suitable for an oil field water injection well, it is little that the valve ball resistance is backed down in the water injection of " Y " shell body, and loss of pressure is little, no single current valve valve bonnet is convenient for wash, has reduced post workman's intensity of labour, the normal water injection of guarantee water injection well.
Description
Technical field
This utility model relates to beam-pumping unit caput Equi Asini and light rod connecting device, specifically a kind of oblique ball-and-seat without cover of water injection well.
Background technology
Water injection well in oil fields is to maintain the main source of stratum energy, in flooding production, the ball-and-seat effect of water injection well is: when water injection well conduit wiring piercing, water-injection station termination of pumping prevent stratum guttation shake out cause sand to bury, sand plug oil reservoir and water injection string, make water injection well occur shorting or noting not intaking, well of even lying., in use there is certain defect in the most on-the-spot water injection well ball-and-seat used, one is often because tightening plug damage ball-and-seat valve bonnet, causes single current valve bonnet to deform；Two when being normal water filling, because valve body is vertical structure, needs to back down valve ball resistance big, and build-up of pressure loss is big；Three is because being produced-water reinjection, impure many, the easy fouling of valve bonnet, cleans difficulty.Post labor strength is big, affects the normal water filling of water injection well.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, a kind of oblique ball-and-seat without cover of water injection well of design.
This utility model is realized by following technical proposals:
The oblique ball-and-seat without cover of water injection well, including: housing, plug, valve ball, blind, valve seat.Described water injection well oblique single current without cover valve housing be cylinder constitute "
Y
" type body, the top of lower end import is provided with valve seat, and the top of valve seat is provided with valve ball, and the top of housing is provided with internal thread hole, in internal thread hole on have plug, the left end of housing is provided with outlet, and the left end of outlet is provided with blind.
The central upper portion of the housing in the oblique ball-and-seat without cover of above-mentioned water injection well with vertical line angle is
30
°～
45
°。
Blind in the oblique ball-and-seat without cover of above-mentioned water injection well is " one " font, or " cross " font, and stainless steel material makes.
The beneficial effects of the utility model are: be applicable to water injection well in oil fields, "
Y
" to back down valve ball resistance little in shell body water filling, the pressure loss is little；Valve bonnet without ball-and-seat, it is simple to clean, reduces the labor intensity of post workman, ensures the normal water filling of water injection well.
