Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a multifunctional balancing valve. Background Art

[0002] A balancing valve is a valve with special functions. It is suitable for places where there is a large pressure difference or flow difference in various parts of the pipeline. The balancing valve is used to reduce or balance the difference to adjust the relative balance of pressure or flow on both sides.

[0003] For example, Chinese patent application No. 202320415661.5 discloses a balancing valve, which is configured by coordinating structures such as a valve disc, a seal, an annular groove, an elastic support member, and a valve plug. After the valve body is sealed by the valve plug, the liquid cannot be discharged, which increases the liquid pressure inside the valve body at one end of the liquid inlet. At this time, the liquid in the inner cavity of the annular groove squeezes the side wall of the annular groove away from the valve disc, so that the inner wall of the seal fits tightly with the outer surface of the valve plug, increasing the fit between the seal and the valve plug, and avoiding as much as possible the friction between the valve plug and the tension block when adjusting the position of the valve plug in the existing balancing valve structure. After long-term friction, the connection between the valve plug and the tension block will produce a gap due to wear, affecting the sealing performance of the tension block;

[0004] In the above scheme, although the sealing performance is improved, it requires human operation, which wastes manpower and is slow to operate. In order to solve the above problems, we have designed a multifunctional balancing valve. Utility Model Content

[0005] The utility model provides a multifunctional balancing valve to solve the problems raised in the above background technology.

[0014] The pressure at both ends of the valve body can be monitored in real time through the pressure measuring cylinder, mounting bracket, rope spring, extrusion plate and pressure sensor, and the information can be transmitted to the controller. After comparison, the controller controls the hydraulic cylinder to move the pressure regulating valve plate, controls the water outlet area at one end of the connecting hole, and thus controls the pressure difference on both sides to remain unchanged; by adjusting the motor to drive the flow valve plate to rotate, the overlap of the water outlet and the water inlet is changed to change the flow rate.
