Abstract
The utility model discloses a magnetic valve for minimizing crude oil pipeline transportation wax deposit, designed for minimizing pipeline wax deposit and reducing oil transportation cost. A valve seat of the magnetic valve is in connection with an axial center aperture of a lower valve body; a neodymium iron boron circular magnetic steel is arranged in an annulus between the lower valve body and the valve seat; the valve body is in connection with an upper valve body; a valve stem and a valve core penetrate a center stepped hole of the upper valve body; the valve core is located at a valve seat valve port; the center stepped hole of the upper valve body is in communication with an axial oil outlet in a sidewall of the valve body; the annulus between an upper hole enlargement hole and the valve stem is filled with sealing fillers; the top end of the upper valve body is in connection with a valve cover; the upper side of the valve cover is in connection with a valve stem sleeve and a hand wheel. The magnetic valve can be installed at a first station of a crude oil gathering pipeline to magnetize crude oil passing through the valve and reduce crude oil wax precipitation point temperature so as to save energy. In addition, the magnetized crude oil can minimize waxiness coalescence on inner walls of the gathering pipeline and reduce wax precipitation hardness, thereby reducing pitching pigging operation difficulty and pigging frequency, raising crude oil gathering and transportation flow velocity and quantity of flow and reducing oil transportation cost.
Description
Technical field
The utility model relates to a kind of Magnetic valve that reduces the crude pipeline transportation wax deposition, belongs to crude pipeline transportation paraffin removal technical field.
Background technique
Long celebrating oil field is located in NORTHWEST CHINA portion area, and output is the higher paraffine crude oil of paraffin content.In oil recovery process, for avoiding because the condense viscosity of crude that causes of wax reaches problems such as stopping up oil pipe greatly, need heat and modification is carried crude oil, cost is very high.Crude oil is after magnetization is handled, and the characteristics such as crystalline state of its wax precipitation point and wax all will change, and this is conducive to reduce the heating-up temperature of Crude Oil Transportation, reduces expenses.
Summary of the invention
The purpose of this utility model is to provide a kind of Magnetic valve that reduces the crude pipeline transportation wax deposition, and it can reduce the pipeline wax deposition, reduces oil transportation cost.
Concrete technological scheme of the present utility model is as follows:
The valve seat of this Magnetic valve is connected in down in the valve body axial center hole, and the neodymium iron boron annular magnetic steel is located at down in the annular space between valve body upper end hole and the valve seat, and following valve body is connected upper valve body by sealing gasket with bolt.Be provided with axial central stepped in the upper valve body, be provided with externally threaded valve rod and bottom thereof spool that connect, taper and run through this central stepped, spool is seated at the valve port place on valve seat top.Undergauge hole, upper valve body bottom is communicated with the radially oil outlet in the sidewall, is provided with the motive sealing filler in the annular space between hole enlargement hole, top and the valve rod.The upper valve body top connects valve gap, and the valve gap top connects valve stem casing, the valve stem casing valve rod that is threaded, and handwheel is connected in valve stem tip.
This Magnetic valve can be installed in the initial station of pumping well single tube petroleum pipeline front end or crude oil gathering pipelines, and the crude oil of this valve of flowing through is magnetized, and reduces the wax precipitation point temperature of crude oil, to obtain energy-saving effect.And, can reduce wax coalescent on the collector and delivery pipe inwall through magnetized crude oil, reduce the hardness of wax deposition, thereby reduce operation easier and the pigging frequency of delivery pipe cleaning, improve the defeated flow velocity of collection and the flow of crude oil, reduce oil transportation cost.
Description of drawings
Fig. 1 is for reducing the Magnetic valve schematic representation of crude pipeline transportation wax deposition.
Fig. 2 is the A-A sectional view among Fig. 1.
Embodiment
With reference to Fig. 1 and 2 embodiment of the present utility model is further specified:
Embodiment:
This Magnetic valve comprises down valve body 1, oil inlet end flange 2, valve seat 3, bolt 4, neodymium iron boron annular magnetic steel 5, sealing gasket 7, spool 8, upper valve body 9, radially oil outlet 10, oil outlet end flange 11, motive sealing filler 12, valve gap 13, valve stem casing 14, valve rod 15, handwheel fixing bolt 16 and handwheel 17:
The bottom of the valve seat 3 of tubular is outer hexagonal shaped; Valve seat 3 is threadedly connected to down in valve body 1 axial center hole, and neodymium iron boron annular magnetic steel 5 is located at down in the annular space between valve body 1 upper end hole and the valve seat 3, and following valve body 1 is connected upper valve body 9 by sealing gasket 7 with bolt 4.Be provided with axial central stepped in the upper valve body 9, be provided with externally threaded valve rod 15 and bottom thereof spool 8 that connect, taper and run through this central stepped, spool 8 is seated at the valve port place on valve seat 3 tops.Undergauge hole, upper valve body 9 bottom is communicated with the radially oil outlet 10 in the sidewall, is provided with motive sealing filler 12 in the annular space between hole enlargement hole, top and the valve rod 15.The upper valve body 9 tops valve gap 13 that is threaded, valve gap 13 tops connect valve stem casing 14 by bolt, valve stem casing 14 valve rod 15 that is threaded, handwheel 17 is connected in valve rod 15 tops by fixing bolt 16.
The working principle of this Magnetic valve is as follows:
The magnetic line of force of neodymium iron boron annular magnetic steel 5 passes metal body valve port, spool 8 and upper valve body 9 Cast Steels of valve seat 3, constitutes high magnetic fields loop 6, and the crude oil of flow through 8 of valve seat 3 and spools is magnetized.Spool 8 can be driven by handwheel 17, in the upper and lower movement in valve port place, regulates the circulation gap of fluid.Because the mechanical strength of Nd-Fe-B permanent magnetic steel is little, so the split type valve body mode that adopts flange to connect can protect magnet steel not bear local mechanical pressure, unlikely fragmentation when the assurance valve is fastened.Valve seat 3 adopts high-strength magnetic stainless steel material, and its outer six side's screw-in structures then allow down valve body 1 selection Normal Steel Casting, thereby reduces valve cost processed.
