Working principle of high pressure solenoid valve-Hushan Valve Manufacturing (Shanghai) Co., Ltd.

I. Overview The high-pressure solenoid valve is divided into two types: the direct-acting type and the pilot-type structure. The sealing structure is mostly piston type (disc piston structure). It is light and flexible. The guiding device inside the valve makes the piston move up and down without deviation from the center, effectively avoiding the piston stuck in the cylinder. The shortcomings in the valve cavity. The pre-designed three-dimensional sealing structure can be flexibly matched with different sealing materials, and the valve can be disclosed up to zero. High pressure solenoid valve with brass high pressure solenoid valve and stainless steel "target=_blank> stainless steel high pressure solenoid valve Second, high-pressure solenoid valve installation matters 1. Please refer to the instruction manual of the product before installation, whether it can meet your application requirements. 2. The pipeline should be cleaned before use. If the medium is not clean, a filter should be installed to prevent the normal operation of the impurity barrier solenoid valve. 3. The solenoid valve after long-term deactivation should be used before the condensate is cleared; when the parts are removed and washed, the parts should be placed and restored. 4, the solenoid valve is generally one-way work, can not be reversed, the arrow on the valve is the direction of movement of the pipeline fluid, must adhere to differences. 5. When the solenoid valve is working again in the icing site, it should be heated or disposed of, or set the insulation measures. 6, the solenoid valve is installed with the normal valve body level, the coil is vertical upwards, some products can be installed freely, but it is best to be vertical when conditions permit, to increase the service life. 7. After the electromagnetic coil lead wire (connector) is connected, it should be confirmed whether it can be sturdy. The contact of the electrical component should not tremble. Looseness will cause the solenoid valve to not work. It is better to use a bypass for the solenoid valve that needs to consume the work continuously, which is convenient for maintenance and does not affect consumption. Third, the high-pressure solenoid valve structural characteristics Pilot piston type, air force, naval accessory products Compact design, exquisite appearance, low temperature rise, no noise, zero disclosure Fast response, high frequency German craft, export series, reliable quality If the medium contains impurities, a filter must be installed before the valve (screen is greater than or equal to 80 mesh / cm 2); and there is no solidification or crystal table phenomenon. Fourth, the working principle of high pressure solenoid valve Normally closed: When the coil is energized, the pilot spool is sucked, the pilot hole is opened, the upper chamber of the valve is relieved, the pressure of the piston is pushed forward by the lower chamber, and the solenoid valve is opened; when the coil is de-energized, the pilot spool is reset 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 solenoid valve is closed. Normally open: When the coil is energized, 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 solenoid valve is closed. When the coil is de-energized, the pilot spool is reset by the spring, the pilot hole is opened, the upper chamber of the valve is relieved, the piston is pushed by the medium pressure of the lower chamber, and the solenoid valve is opened.
