Description

Technical Field

[0001] The invention relates to the technical field of ball valves, and in particular to a multi-directional regulating ball valve for multi-directional fluid control and adaptive regulation. Background Art

[0002] At present, multi-way ball valves are often installed on pipelines for conveying liquids to carry out direct or diverted delivery of liquids. During the delivery process, it is inevitable that a certain amount of gas will appear in the pipeline. The sources of the gas mainly include direct air intake, free air intake and gas released from dissolving in water. Especially when using intermittent pipelines to convey liquids with higher temperatures, gas is more likely to be generated. When gas appears in the pipeline, it is easy to cause unbalanced pressure in the pipeline and the ball valve, resulting in vibration, which is easy to cause leakage at the connection between the pipeline and the ball valve. The existing ball valves can often only be set to a fixed outlet pressure, and cannot be adaptively adjusted according to the pressure conditions in the pipeline and the valve body channel, and thus cannot discharge the gas generated in the pipeline, causing the gas to flow from one pipeline through the ball valve to another, so that the leakage cannot be slowed down and the sealing is poor.

The opening sensor is a rotary magnetic encoder. The extended shaft of the opening sensor is connected to the valve stem 22 through a coupling, and the opening sensor is electrically connected to the control module for real-time monitoring of the opening of each flow channel. The control module controls the electric actuator 21 to drive the valve stem 22 and the valve ball 23 to rotate in a direction and at an angle according to the pressure signal in each flow channel of the butterfly valve, and compares the monitored actual pressure value with the expected set value, calculates the difference and proportional relationship between the two to calculate the required opening value increment of the valve stem 22 and the valve ball 23, and outputs the electrical signal of the opening sensor for a second time to control the electric actuator 21 to drive the valve stem 22 and the valve ball 23 to rotate and adjust, which has the effect of automatically and accurately adjusting the opening of the ball valve. Further, such as Figure 2 , Figure 3 and Figure 5As shown, the center of the valve stem 22 is provided with an exhaust passage 221 along its axial direction, and the outer surface of the valve stem 22 is located inside the valve seat 2 and is provided with two exhaust holes 223 symmetrical about the axis. The exhaust passage 221 is communicated with the exhaust hole 223 upwardly and with the cavity of the valve ball 23 downwardly. The exhaust passage 221 is a cylindrical passage and its diameter is less than half of the diameter of the valve stem 22. A sealing member 3 is sleeved on the outer surface of the valve stem 22. The sealing member 3 is located inside the valve seat 2 and two connecting rods extending upward to the housing of the electric actuator 21 are bolted to the top of the sealing member 3. A cylinder is also provided in the housing of the electric actuator 21, and its output rod is connected to the connecting rod up and down. The cylinder is electrically connected to the control module, and the pressure values ​​of each flow channel of the ball valve are displayed on the display in the controller module, and the pressure values ​​are displayed by the numerical value. The comparator compares the difference between the real-time pressure value and the expected pressure value to determine whether the pressure of each flow channel is within an appropriate range.

During the movement of the seal 3, the exhaust hole 223 is switched between closed, open, and closed again, so that part of the gas in the valve ball 23 is discharged upward along the exhaust channel 221 and finally discharged from the exhaust hole 223, so as to achieve the effect of balancing the internal pressure of the butterfly valve. The controller module makes another judgment based on the difference between the real-time pressure value and the expected pressure value. When the difference is still greater than the preset difference, the above operation is repeated until the pressure reaches a balance. When the difference is still much higher than the preset difference after multiple adjustments, the alarm will issue a fault alarm prompt. Furthermore, a row of grooves 222 are provided on the inner wall of the exhaust duct 221 along its central axis to provide multi-directional resistance to the water inside the exhaust duct 221. A number of micro through holes are provided on the side wall of the valve seat 2 to balance the internal and external pressures of the valve seat 2. A row of grooves 222 forms a threaded structure in the exhaust duct 221. A PTFE membrane core is also filled in the threaded structure in the exhaust duct 221 to discharge gas and block water, thereby achieving the goal of discharging gas outward while preventing water inside the channel from overflowing upward, thereby achieving pressure balance inside the valve.

[0018] When the above embodiment is working, the pressure value in the first flow channel is monitored by the first pressure sensor 121, the pressure value in the second flow channel is monitored by the second pressure sensor 131, and the pressure value in the third flow channel is monitored by the third pressure sensor 141. The first pressure sensor 121, the second pressure sensor 131 and the third pressure sensor 141 transmit the monitored pressure signals to the controller module. The display in the controller module displays the pressure value of each flow channel of the ball valve, and compares the difference between the real-time pressure value and the expected pressure value through a numerical comparator. When the difference is greater than the preset difference, the controller module controls the start gas. The cylinder drives the seal 3 to move up and down through the connecting rod. During the movement of the seal 3, the exhaust hole 223 is switched between closed, open and closed again, so that part of the gas in the valve ball 23 is discharged upward along the exhaust duct 221 and finally discharged from the exhaust hole 223, so as to achieve the effect of balancing the internal pressure of the butterfly valve. The controller module makes another judgment based on the difference between the real-time pressure value and the expected pressure value. When the difference is still greater than the preset difference, the above operation is repeated until the pressure is balanced. When the difference is still much higher than the preset difference after multiple adjustments, the alarm will give a fault alarm prompt.
