Abstract
The utility model discloses a flow control valve, which is simple, practical and convenient in adjustment. The inner cavity of the flow control valve is divided into a first cavity and a second cavity by means of a valve block with a through hole. A valve plug body in the first cavity is connected with a pull rod. The pull rod is configured to extend out of the first cavity. Inside the first cavity, a spring is sleeved onto the pull rod. Under the action of the elastic force of the spring, the conical head of the valve plug is blocked in the through hole. Outside the first cavity, the pull rod is connected with a regulating rod. The inner side of the regulating rod is provided with an arc-shaped dial and a regulating disc. A regulating bolt in a bolt hole of the regulating disc extends out of the bolt hole to abut against the arc-shaped dial. The abutting length of the regulating bolt is sequentially increased along the arc-shaped circumference of the arc-shaped dial. A pinch roller is arranged between the regulating rod and the arc-shaped dial. The regulating rod is rotated towards the abutting-length sequentially increasing direction thereof, so as to drive the pinch roller to roll the arc-shaped dial. Therefore, the conical head of the valve plug is driven to gradually get away from the through hole, so that the flow of the heavy oil is increased.
