Abstract
The utility model relates to a constant flow control valve specially used for oilfields, which belongs to a flow control valve and comprises a control rod, a flow control hole, a piston, a valve body, an oil inlet, a spring, an oil outlet and a pressure compensation sliding bush. The constant flow control valve is characterized in that the control rod is connected with the pressure compensation sliding bush; the lower end of the pressure compensation sliding bush is provided with the piston and the spring; the flow control hole is drilled on the side of the valve body, the oil inlet is drilled in the front of the valve body, and the oil outlet is drilled at the back of the valve body; and the pressure compensation sliding bush, the piston, the spring and the control rod are arranged in the valve body. The utility model has the advantages of high temperature resistance and constant flow control.
Description
Technical field
The utility model belongs to a kind of flow control valve, the special-purpose constant flow rate control valve in particularly a kind of oil field.
Background technology
At present, the oilfield exploitation height needs when coagulating oil be higher than 120 quantitative liquids of spending toward the delivered downhole temperature, and there is the inaccurate problem of metering in the moving controlled quentity controlled variable of regulating of armrest.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of oil field special-purpose constant flow rate control valve, this flow control valve, predetermined amounts regulates the pressure compensation sliding sleeve, by sliding up and down of spring regulating piston, remains on the position of scheduled volume, if ambient pressure and flow change, open in the Flow-rate adjustment hole, keeps predetermined amount of flow, reaches the purpose of automatic adjusting flow.
The technical scheme that its technical problem that solves the utility model adopts is: the special-purpose constant flow rate control valve in a kind of oil field, form by control lever, Flow-rate adjustment hole, piston, valve body, fuel feed hole, spring, oil outlet and pressure compensation sliding sleeve, its special character is: control lever connects the pressure compensation sliding sleeve, pressure compensation sliding sleeve lower end dress piston, spring, the valve body side is drilled with the Flow-rate adjustment hole, the front is drilled with fuel feed hole, the back is drilled with oil outlet, and pressure compensation sliding sleeve, piston, spring, control lever are contained in the valve body.
The beneficial effects of the utility model are: high temperature resistant, and constant control flow.
