LT942X piston flow control valve
Piston flow control valve adjustment mechanism should be crank-slider mechanism, the closure of the slider cylinder or cone piston. In the cylinder inside the cylinder guided by the guide along the center of the pipeline for axial movement, thus changing the flow area, in order to achieve regulation of flow and decompression. Connection with the pipe flange connection, flange connection size, the length of the structure in line with the corresponding GB requirements.
LT942X piston flow control valve structure
Piston flow control valve Structural Features Description:
Piston flow control valve by the body , piston , crank , connecting rod , energy dissipation devices, stems , bushings , seat, seals and other major components.
Piston flow control valve body for the streamlined axial symmetric flow of fluid in the valve body can be well without turbulence-induced, can significantly reduce the valve noise and vibration. To ensure that the valve also has good anti-cavitation under high pressure drop, which allows cavitation coefficient should not exceed 0.4.
Piston flow control valve has excellent linear adjustment performance, so that the control system through the outlet pressure transmitter feedback signal to regulate the valve to maintain a constant water pressure.
Piston flow control valve has a reliable sealing performance, the valve is in the fully closed state, to ensure that no leakage. Piston flow control valve in normal operating conditions, no jamming and harmful vibration, to ensure safe and reliable operation of equipment. Life of not less than 30 years. Piston flow control valve has good anti-blocking ability. It is suitable for fluids with sediment and small particle impurities. Piston control valve in the maximum working pressure and moving water hoist operating conditions, to ensure that the overall anti-thrust safe and reliable, does not occur harmful vibration.
Piston flow control valve drive motor driven. Motor drive device should have good water resistance, should be flexible, safe and reliable, manual torque to meet national standards. Piston flow control valve electric devices include motor, deceleration worm gear, mechanical limit adjustment mechanism, torque control mechanism, stroke control mechanism, opening instructions and manual manual electric conversion device. Piston flow control valve of the electric device using the integration of mechanical and electrical design, configuration is the operation of the control box.
Piston flow control valve actuator has the following properties:
Valve overload protection;
Valve stroke protection
· Manual / electric switching device;
Valve position indication device;
Valve opening and closing contacts, the contact leads out should meet the requirements of local and remote control room.
1, good linearity: due to the internal structure of the valve with a special design, the fluid flow control characteristics of a good linearity, even in the first 10% of the trip still has a good flow control effect.
2, Anti-cavitation, anti-vibration: Make full use of the principle of fluid dynamics to design the runner to eliminate the damage caused by cavitation and vibration to the pipe network and greatly improve the service life of the valve and pipe.
3, Reliable work: reasonably designed runner and seal type, the valve can be applied to the fluid containing sediment and other small particles of impurities, will not result in closed due to debris and lead to leakage or control failure.
4, high-pressure energy dissipation: Even in the case of high pressure, the valve can effectively eliminate high-pressure energy, the high pressure reduced to low pressure, and will not produce vibration and cavitation, effectively ensure the service life of the valve.
5, excellent material selection: valve key parts such as valve seat, stopper, rail and other components are made of special stainless steel, this material is wear-resistant, cavitation-resistant, three times the hardness of ordinary stainless steel.
6, floating valve seat: the valve seat and the cone connection using a special silicone adhesive, high viscosity, shear-resistant. Floating valve seat in the valve seat when the self-centering effect, the seal more reliable.
7, the fluid resistance is small: The valve advanced structural design, reasonable flow path distribution, so that the pressure drop across the valve down to shadow æ° conducive to saving the entire network of power consumption.
8, the operating torque is small: the opening and closing parts in the valve for the gate, the direction of its movement and the competent fluid flow direction, and the effective force area is small, so open and close the valve required torque is very small, the drive cost can be significantly reduce.
9, long service life: The valve is mainly sealed to the metal counterparts, reliable sealing, fluid erosion resistance strong, easy to be mixed with garbage damage, combined with most parts made of stainless steel, the service life of the valve greatly improved.
LT942X piston flow control valve purposes:
Piston flow control valve is mainly used in waterworks, power plants, water diversion projects and other media for the water pipe network system, play a regulatory pipeline media flow, flow and regulate the role of network pressure.
LT942X piston flow control valve features:
1, The valve is best than the traditional flow control valve is characterized by its structural design and material selection so that it is not afraid of sewage blocking chute, not afraid of scaling phenomenon, easy to jamming. Drive significantly reduced.
2, the valve can automatically adjust the preset value of the pipeline medium parameters, so that it remains constant within a certain accuracy, and the accuracy range can be adjusted.
3, the valve has a good resistance to cavitation erosion characteristics of the valve body wall ribs both rectifier plate, you can disperse the water flow, to prevent cavitation. At the same time, it also reduces valve noise and piston vibration.
4, the valve control system can be integrated electronic circuits, small size, good reliability, high sensitivity, easy installation and commissioning.
5, all off leakage is zero, can be used as a stop valve. There is no need to set another stop valve.
6, such as the degree of control and precision requirements are not high, the valve control can be manual or normal electric form.
7, can be horizontal installation, vertical installation can also be.
