Imported high-temperature solenoid valve
Features of imported high-temperature solenoid valve: The valve cores are all stainless piston type. The piston rings are made of special temperature-resistant and wear-resistant materials. The piston and the metal valve cavity do not produce direct friction. There is no limit on the installation direction of the valve body. Special coil , and adopts a heat-dissipating structure, so it is not easy to burn out and restart after a long stop, and the action is equally sensitive with the lowest starting pressure.
Working principle of imported high temperature solenoid valve After the solenoid is energized, the connecting rod is lifted, and as the rotating shaft begins to rotate, this movement acts on the pilot valve to open the main valve. After the power is turned off, under the action of the armature's own weight and the return spring, the semi-circular After the pilot valve is closed, the main valve is closed by the pressure difference.
The working principle of the normally closed type of imported high temperature solenoid valve. When the coil is energized, the pilot valve core is closed, the pilot hole is opened, the pressure is relieved on the valve, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve is opened. When the coil is deenergized, The pilot valve core is restored by the spring, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the return spring, and the valve is closed.
The working principle of the imported high temperature solenoid valve normally open When the coil is energized, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston throttle hole and the thrust of the return spring, and the solenoid valve is closed. When the coil is powered off, the pilot valve core returns by the spring, the pilot hole opens, the upper chamber of the valve relieves pressure, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve opens.
Installation of imported high temperature solenoid valve
Flushing pipeline. Prevent the iron slag impurities in the pipeline from blocking the solenoid valve, causing the moving iron core to be stuck and unable to open.
The direction of installation of the solenoid valve is that the medium flow direction should be consistent with the direction of the arrow on the valve body, and the solenoid coil should be vertically upward.
Do not install this valve in a low recess in the pipeline to avoid steam condensation, impurities, etc. being deposited in the valve and impeding its operation.
High temperature solenoid valves cannot be used in explosion hazardous situations.
There should be a certain space left at the installation location of the solenoid valve to facilitate heat dissipation and daily and regular maintenance.
