Description
Technical field
The utility model belongs to the valve member technical field, specifically is the anti-blocking adjustable flow control valve of a kind of petroleum pipeline water mixing.
Background technique
Getting into heavy oil development later stage and temperature low, moisture low oil recovery period; Because low temperature, low liquid measure, low crude oil fluidity when moisture are too poor; Make the high well crude oil of oil content be transported to and become very difficult in the metering station, simultaneously, will follow many problems to occur from the shaft bottom; Like the underproduction, back pressure rising, pipeline damage, pipeline obstruction, the leakage of well head thorn, environmental pollution etc., had a strong impact on the production of crude oil.Therefore, be employed in the method for water mixing heating and viscosity reducing in the petroleum pipeline more, recover mobile, keep ordinary production.In the water mixing process, because the moisture difference of every mouthful of well, required watering quantity is also different, moisture high well, and water mixing is few, otherwise, more, therefore, must control to suitable amount to the water mixing of every mouthful of well.At present technically require after the water mixing moisture in the crude oil pipeline to reach at 85% o'clock, be suitable amount.In the prior art, what the control watering quantity adopted is gate valve, latus rectum 32mm; Through the adjustment valve size control water yield, but, often rotate some handwheels because employed valve regulated precision is low; Following flashboard will be opened very big, therefore, does not reach the effect of accurate control watering quantity.
The model utility content
The purpose of the utility model provides a kind of discharge pressure that can reduce petroleum pipeline, effectively prevents to stop up petroleum pipeline, improves oil transportation efficient, and can reach the anti-blocking adjustable flow control valve of petroleum pipeline water mixing of accurate control oil transportation watering quantity.
The technological scheme that the purpose of realization the utility model is taked is: this valve has a straight-through tube valve body; The valve body two ends are communicated with the water mixing pipeline through flange; Be provided with fluid inlet upper channel and fluid output lower channel in the valve body; Two channel connections up and down, it is communicated with position and is provided with the mangetic core assembly that is used for control flow rate, and mangetic core assembly stretches out valve body and is connected with the Flow-rate adjustment assembly through connecting cutting ferrule outward.
Said Flow-rate adjustment assembly has one and is sleeved on the outside cylindrical shell of mangetic core assembly; In the cylindrical shell and between the mangetic core assembly stuffing box packing is housed; The top of stuffing box packing is provided with clamping sleeve, and the outside of clamping sleeve is connected with cylindrical shell through screw thread, and the inside of clamping sleeve is through the valve rod adjusting element that has been threaded; The top of clamping sleeve is equipped with switch handwheel at the top of valve rod adjusting element through fixing bolt through the locking cap that has been threaded.
Said mangetic core assembly by valve rod, valve stifled and traffic channel body forms, wherein, the stifled circular cone structure that adopts of valve is connected the bottom of valve rod, the stifled conical surface of valve and the communication port contact matching of channel connection up and down, the bottom that valve blocks up is fixedly connected with the traffic channel body.
Said traffic channel body is the round column structure of hollow, has the opening that is used for flow control on it.
Said switch handwheel is provided with the dial that is used to show the flow size.
According to the anti-blocking adjustable flow control valve of petroleum pipeline water mixing that such scheme is processed, its beneficial effect is:
1, through hot water is mixed in the crude oil pipeline, exchange heat is carried out in direct and crude oil mixing, thereby makes the crude oil intensification viscosity reduction in the pipeline strengthen mobile;
2, through increasing the water yield in the crude oil pipeline, reach oil-in-water state, reduce the friction (viscosity is exactly the friction between the molecule) between crude oil and crude oil or crude oil and the tube wall, mobile thereby viscosity reduction strengthens;
3, this valve is easy to operate, and the fluid passing capacity is big, does not stop up, and can reduce the resistance of crude oil flow in the crude oil pipeline, improves the ability of oil transportation, has improved oil output;
4, through this control valve, can reach the watering quantity in the accurate control petroleum pipeline, reduce the discharge pressure of petroleum pipeline, improve the practical effect of oil transportation efficient.
