Overview

The LHS941X-16Q/C electric flow and pressure regulating piston valve is a piston type structure. The regulating mechanism of the piston type control valve should be a crank slider mechanism, and the closing slider should be a cylindrical or conical piston. It can move axially along the center of the pipeline guided by guide rails inside the cylinder of the valve body, thus changing the flow area to achieve flow regulation and pressure reduction functions. Mainly used in projects where the medium is water, such as the main network of water pipelines, electricity, and power stations. Mainly used in water treatment plants, power plants, water diversion projects, and other pipeline systems with water as the medium, it plays a role in regulating the flow rate, flow state, and pressure of pipeline media.

Product Features

1. The advantage of this valve over traditional flow control valves lies in its structural design and material selection, which makes it not afraid of sewage blocking the slide, scaling, and easy to get stuck. The driving device has significantly decreased.2. This valve can automatically adjust the pre-set pipeline medium parameter values to maintain a constant accuracy within a certain range, and the accuracy range can also be adjusted. 3. This valve has good resistance to cavitation, and the rib plate on the inner wall of the valve body also serves as a rectifier plate, which can disperse water flow and prevent cavitation. At the same time, it also reduces the noise of the valve and the vibration of the piston.4. The fully closed leakage is zero and can be used as a shut-off valve. No need to install other shut-off valves.5. The control degree and accuracy requirements are not very high, and the control of this valve can be done manually or in ordinary electric form.6. The installation method can be horizontal or vertical.7. The water flow cross-section at any position inside the valve body is a circular structure.

LHS941X-16Q/CElectric flow and pressure regulating piston valveApplication principleThe flow and pressure regulating valve is mainly composed of a valve body, piston, piston guide rail, built-in crank slider mechanism, seal, internal components, etc. The main method is to use a crank slider to drive the piston to move, forming an axially symmetrical annular flow channel inside the valve body, and effectively controlling the flow area to form a flow channel with a decreasing cross-section from the inlet to the outlet, so as to gradually increase the fluid velocity. Through the porous holes in the circumferential direction, a jet collision is formed towards the center of the pipeline, thereby achieving the purpose of energy dissipation, pressure reduction, and flow regulation.The flow and pressure regulating valve has a good energy dissipation effect on the fluid under low flow conditions, effectively preventing cavitation; When operating under high flow conditions, the valve can reduce some of the fluid's energy while retaining some of the fluid's energy. The valve has sufficient overcurrent capacity. Its main advantages are as follows: it can achieve * * control of flow and maintain a constant flow rate; Realize regulation within a large pressure difference range and maintain stable pressure behind the valve; There are two control methods available: manual and electric. The electric flow and pressure regulating valve can also be remotely controlled, allowing operators to make adjustments as needed without the need to be on site.
