HL941X piston type electric multifunction control valve

HL41X piston type pressure regulating valve can realize accurate control of flow, keep constant flow, also can realize adjustment in the range of large pressure difference, keep the pressure behind the valve stable. This product can choose manual and electric control mode, electric flow regulating valve can also achieve remote control, operators do not need to arrive at the scene, can be adjusted according to the need of high precision. The valve is widely used in large water supply projects, water diversion projects often need hydraulic control valve, it is widely used in the flow control field: such as sewage treatment plant, water plant inlet, drainage pipe flow control, drainage system flow scheduling, municipal drainage pipe management and other engineering projects.

The operating principle of HL941X piston electric multifunction control valve is described

Because of the cylindrical piston design, when the valve is opened, the cylindrical piston is not affected by the blind plate force of the fluid, and the valve operating torque is greatly reduced, the torque value is only one third to one fifth of the conventional gate or butterfly valve torque value. The piston opening and closing parts move in a straight line driven by the crank slider mechanism, and the relationship between the valve flow coefficient and valve opening degree is approximately linear function. The stainless steel piston moves on an axis guided by a copper alloy guide. The combination of these two materials prevents sediment from accumulating in between, further reducing valve operating torque.

The blade ring is a fluid guide component in a valve with equi-distributed guide vanes. As the fluid flows through the valve, the upstream stream is forced into bundles of small streams that swirl out and are directed to the center of the line to avoid cavitation and other damage to the line. Because cavitation bubbles are unstable and perishable, they break in the center of the pipeline rather than on the wall surface, so cavitation damage to the pipeline can be avoided. When water flow is cut off or blocked, it flows over a small area, increasing its velocity and lowering its pressure so that bubbles evaporate as the water pressure drops below the evaporative pressure.

The squirrel-cage cylinder is a perforated part extending from the piston. The size of the squirrel-cage groove can be designed according to different working conditions. As the water flows through the cage, it is throttled into a number of high-speed fluids, which shoot out into the center of the passage and collide with each other. Because cavitation is contained in the center of the flow channel, the energy will cancel each other out or gradually decay through the center of the pipeline without causing vibration or cavitation damage to the pipeline. The velocity energy (kinetic energy) of the fluid is converted into pressure energy through the piston valve.
