Description
Technical Field

Background
The valve is widely applied in pipeline engineering, and the valve is of a straight-through type, and consists of a valve body, a valve core, a valve rod and a hand wheel, wherein the hand wheel drives the valve rod and the valve core to rotate so as to achieve the purpose of opening and closing the valve. However, the through-type valve can only realize one inlet and one outlet, is suitable for a simple household pipeline system, is not suitable for an industrial pipeline system with a complex design, and therefore, the three-type flow regulating valve appears in the market.
The three-way flow regulating valve generally comprises a valve body with a liquid inlet pipe and two liquid outlet pipes, wherein a water passing cavity is formed in the valve body, the liquid inlet pipe and the two liquid outlet pipes are communicated with the water passing cavity, a valve core used for controlling the liquid inlet pipe to be communicated with or separated from the two liquid outlet pipes is arranged in the water passing cavity, and a worker realizes the regulation of the liquid outlet flow of the two liquid outlet pipes by rotating the valve core, for example, a three-way valve with a micro regulating function disclosed by application number 201820165634.6, a flow dividing valve with a flow regulating function disclosed by application number 201610349846.5, a three-way flow regulating valve disclosed by application number 201521029643.5 and the like.
However, the three-way flow regulating valve with the existing structure has obvious defects: when the liquid outlet flow of one liquid outlet pipe is smaller, the general operation should be that a worker rotates the valve core to enable the liquid outlet pipe to distribute more flow, but the rotation of the valve core also inevitably causes the liquid outlet flow of the other liquid outlet pipe to be smaller, that is to say, the existing three-way flow regulating valve cannot accurately regulate the liquid outlet flow of the two liquid outlet pipes simultaneously. Therefore, the conventional method is to make a compromise between the required liquid flow rates of the two liquid outlet pipes, that is, to rotate the valve core to a suitable position so that the liquid flow rates of the two liquid outlet pipes can be relatively close to the required flow rate values, but the adjustment method has the disadvantage of causing inaccuracy in the liquid flow rates of the two liquid outlet pipes.
