Abstract
A novel check valve of viscous oil comprises a flange, a valve body, a spring, a valve plug, a valve seat, a righting barrel and a baffle, is characterized in that the valve body is a cylindrical valve and equipped with a annular boss at the inside of the top. The annular boss is equipped with a female thread at the bottom, and welded with a flanged joint at the center of the top. The valve seat is a cylindrical seat, equipped with a pin thread at the top and a taper seat of valve plug as well as a welded flanged joint at the center of the bottom. Between the valve body and the valve seat is thread connection, between the top of the valve seat and the annular boss of the valve plug is equipped with a baffle which is welded the righting barrel at the center, which is inserted with a taper valve plug stem. Between the valve plug stem and the baffle is equipped with a spiral. The utility model has the advantages of timely reset, reliable sealing, prevention of the return of viscous oil into the water mix pipeline and the consequent blockage of the water mix pipeline, supply a reliable guarantee of collecting and transportation of the water mix of viscous oil.
Description
One, technical field
The utility model relates to the novel viscous crude ball-and-seat that a kind of thickened oil recovery water mixing is used.
Two, background technology
At present in the viscous crude field oil recovery process, heavy oil gathering is the big problem of restriction heavy oil production, and viscosity of thickened oil is up to several thousand or up to ten thousand Where pools, does not go out in that the gathering and transferring process of generally heating is defeated, generally all adopts the water mixing gathering and transferring process of heating.Ball-and-seat is all installed by the import department of advancing the viscous crude pipeline at active water, prevents that viscous crude from entering the water mixing pipeline.Used ball-and-seat all is a level dress ball formula ball-and-seat, and ball is in free state, does not have the gigback of pressure, when the little appearance of watering quantity intermittently the time, ball can not in time reset, and viscous crude enters the water mixing pipeline, untimely processing will be stopped up water mixing pipeline and oil pipeline, influences viscous crude production.
Three, summary of the invention
The purpose of this utility model provides a kind of novel viscous crude ball-and-seat, solves ball-and-seat that above-mentioned prior art exists and resets untimelyly, and the water mixing pipe that results in blockage influences the problem of heavy oil gathering.
The technical solution of the utility model realizes in the following manner:
The utility model by flange, valve body, spring, spool, valve seat, set upright tube and baffle plate is formed, it is cylindrical to it is characterized in that valve body is made as, inside, upper end is provided with annular table, is provided with box thread below the annular table, the upper end central part is welded with flange socket; Valve seat is made as cylindrical, and top is provided with male thread, and lower central part is provided with the spool conical seat, and the lower end central part is welded with flange socket; Be threaded between valve body and the valve seat, be pressed with baffle plate between the annular table of valve seat upper end and valve body, its centre is welded with sets upright tube, sets upright the bar that is inserted with taper valve core in the tube, is provided with helical spring between valve core rod and the baffle plate.
Flange, flange socket, baffle plate are set upright the center of tube, valve body, spool and valve seat all on same center line.
Compared with the prior art the utility model has reset timely and reliable sealing advantage, has prevented viscous crude backflow water mixing pipeline, causes water mixing pipeline clogging, fails to viscous crude water mixing collection reliable assurance is provided.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model
1-flange 2-valve body 3-spring 4-spool 5-valve seat 6-baffle plate 7-sets upright tube among the figure
Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is by flange 1, valve body 2, spring 3, spool 4, valve seat 5, baffle plate 6 and set upright tube and 7 form, and it is cylindrical to it is characterized in that valve body is made as, and inside, upper end is provided with annular table, is provided with box thread below the annular table, and the upper end central part is welded with flange socket; Valve seat is made as cylindrical, and top is provided with male thread, and lower central part is provided with the spool conical seat, and the lower end central part is welded with flange socket; Be threaded between valve body and the valve seat, be pressed with baffle plate between the annular table of valve seat upper end and valve body, its centre is welded with sets upright tube, sets upright the bar that is inserted with taper valve core in the tube, is provided with helical spring between valve core rod and the baffle plate.
The ball-and-seat outlet is connected on below the wellhead back pressure valve in concrete the application, and spool is upwards vertically installed, and the ball-and-seat import is connected with the water mixing pipeline by a U-shaped pipe.When normal water mixing, current with taper valve core to pressing down, valve core rod compression spring, ball-and-seat is opened, water is mixed into viscous crude pipeline, the dilution viscous crude is carried viscous crude.Low or when stopping water mixing when water mixing pressure, spool is set upright under the effect with spring and is in time closed ball-and-seat setting upright tube, because of the vertical installation of ball-and-seat, be water entirely in the valve pocket, reflux even have a bit, what reflux also is water, what beat on the baffle plate all is pore, and viscosity of thickened oil is big, also can't pass baffle plate, guaranteed that viscous crude returns to advance the water mixing pipeline, guaranteed the normal operation of heavy oil gathering.
Claims (2)
1, a kind of novel viscous crude ball-and-seat, by flange, valve body, spring, spool, valve seat, set upright the tube and baffle plate form, it is cylindrical to it is characterized in that valve body is made as, inside, upper end is provided with annular table, be provided with box thread below the annular table, the upper end central part is welded with flange socket; Valve seat is made as cylindrical, and top is provided with male thread, and lower central part is provided with the spool conical seat, and the lower end central part is welded with flange socket; Be threaded between valve body and the valve seat, be pressed with baffle plate between the annular table of valve seat upper end and valve body, its centre is welded with sets upright tube, sets upright the bar that is inserted with taper valve core in the tube, is provided with helical spring between valve core rod and the baffle plate.
