Important applications of solenoid valve dosing machines
Mining dosing solenoid valves are made of PVC, PP, PPH, PTFE and other materials. The characteristics of the solenoid valve dosing machine are fluid and metal parts protection, right-angle structure of inlet and outlet, no dead corners, no deposition of particulate residue, no blockage, and compact structure. Easy to maintain.
When the solenoid valve doser is plugged in, the magnet coil generates electromagnetic force to lift the shut-off component from the valve seat, and the valve opens. When the solenoid valve is powered off, the electromagnetic force subsides, and the spring presses the shut-off component against the valve seat. The valve is closed. The ball valve seal is reliable. It has two kinds of sealing surfaces. At present, various fluoroplastics are widely used in the sealing surfaces of ball valves. The sealing is cost-effective and can achieve complete sealing. It is also widely used in vacuum systems. Temperature regulating valves It works based on the principle of liquid expansion. If the temperature in the sensor rises, the liquid filling will expand due to heat, and the valve will close under the influence of the operating piston to cool the medium. The set point button can be adjusted step by step, and the electric 2-way valve can Read from the scale. All thermostats are equipped with over-temperature safety protection devices.
Solenoid valve dosing machines can be divided into 6 branches based on differences in valve structure and material and basic principles: direct-acting diaphragm structure, stepped direct-acting diaphragm structure, pilot-operated diaphragm structure, direct-acting piston structure, stepped type Direct-acting piston structure, pilot-operated piston structure. Normally, the solenoid valve is installed horizontally, as indicated by the arrow of the solenoid valve. The direction cannot be reversed, and the oil cannot flow backwards.
Swing check valves are divided into three categories: single-piece, double-piece and half-piece. These types are usually divided according to the valve diameter, in order to prevent the hydraulic impact from weakening when the medium stops flowing or reverses the flow. When the power is cut off, The spring force of the pilot solenoid valve closes the pilot hole, and the inlet pressure quickly passes through the bypass hole, creating a pressure difference from low to high around the cut-off valve. The liquid pressure pushes the cut-off valve component downward to close the valve.
