Abstract
A replaceable multi-function check valve comprises a shell (1), a wire plug (2), a valve cover (3), a valve ball (4), a valve seat (5), an inlet (6) and an outlet (8). The shell (1) is of cylindrical tube structure, a vertical outlet (8) is arranged on the side of the upper portion of the shell (1), an internal thread which is matched with an external thread of the wire plug (2) is arranged at the upper portion of a central hole, two steps are arranged inside and outside of the lower portion of the shell body (1), the diameter of the inlet (6) of the lower portion of the shell (1) is smaller than that of the shell (1), and an internal thread which is matched with an external thread of the valve cover (3) is arranged at the upper portion of the inlet (6). Four oval flow holes are arranged at the upper portion of the valve cover (3), an internal thread which is matched with an external thread of the valve seat (5) is arranged at the lower portion of the valve cover (3), a horn mouth is arranged in the center of the valve seat (5), and the valve ball (4) is arranged on the horn mouth. A valve core is replaced at an oil-producing site, replacement time of the multi-function check valve is shortened, and environmental pollution and crude oil damage arising from cutting of a pipeline are avoided. Meanwhile, the multi-function check valve can be used as a three direct links to connect the pipeline, transform a procedure, and improve construction progress.
Description
Technical field
The utility model relates to one-way valve architecture advances technology, specifically a kind of replacing formula Multifunctional single pass valve.
Background technique
In the crude oil production process, flow backwards for preventing conduit wiring piercing liquid, one-way valve is installed outside metering station usually.One-way valve has vertical and horizontal, in valve ball is arranged.Owing to reasons such as the long-term bumps of liquid measure impact, corrosion in water, valve ball and valve seat, easily cause the one-way valve damage and be not closed completely.Mostly be greatly welding because of its Placement simultaneously, when breaking down, need to will change after the valve body cutting.Not only on-the-spot replacing workload is large, also causes oil and gas leakage, not only danger but also befouling environment.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of replacing formula Multifunctional single pass valve is provided.
Technical solutions of the utility model comprise: housing, plug, valve bonnet, valve ball, valve seat, import, outlet.The housing of its Changable type Multifunctional single pass valve is the cylindrical tube body structure, upper side is provided with vertical outlet, center hole top is provided with internal thread and cooperates with the plug outside thread, the bottom of housing is inside and outside respectively a step, the diameter of lower inlet is less than the diameter of housing, and the top of import is provided with internal thread and cooperates with the valve bonnet outside thread.
Valve bonnet top in the above-mentioned Changable type Multifunctional single pass valve is provided with four oval flowing holes, and the bottom also is provided with internal thread and cooperates with the valve seat outside thread, and the valve seat center is provided with horn mouth, and valve ball is sitting on the horn mouth.After valve bonnet, valve seat, valve ball damage, valve bonnet can be unloaded and dismantle valve seat and change.Valve bonnet is unloaded, also can work as threeway and use, be convenient to flow process and connect.
The beneficial effects of the utility model are: replaceable spool when recovering the oil on-the-spot the use, reduce the time of changing one-way valve pollution and the crude oil loss of having avoided the cutting pipeline to cause greatly.Also can work as threeway and use, constructability connects, and carries out workflow reengineering, improves construction speed.
