The working principle of high temperature solenoid valve, the function and application of high temperature solenoid valve

The role and application of high-temperature solenoid valve The high-temperature solenoid valve is a pilot-operated direct-acting solenoid valve. It is widely used in shipbuilding heavy industry, testing equipment, heating equipment, hydraulic equipment, etc., in thermal conduction systems with operating temperatures above 300°C. For example, in the drainage system of power station exhaust pipelines and the exhaust system of evaporators, the main purpose is to perform two-position automatic adjustment and remote control of the medium in the pipelines. The high-temperature solenoid valve is a pilot-operated direct-acting solenoid valve, which mainly plays the role of remote control and two-position automatic adjustment of the medium in the pipeline. High-temperature solenoid valves have a wide range of applications and play an indispensable role in heating devices, industrial furnaces, chemical equipment, HVAC, and shipbuilding heavy industry. It can be said that high-temperature solenoid valves are closely related to our lives. Its advanced functions improve the efficiency of pipeline media, and its superior protective performance can reassure users and producers. Solenoid valves are widely used in shipbuilding heavy industry, testing equipment, heating equipment, hydraulic equipment, etc., in thermal conduction systems with working temperatures above 300°C. Heating devices, industrial furnaces, high-temperature soot blowers, drying equipment, steel plants, thermal power plants, textile printing and dyeing, chemical equipment, HVAC, printing equipment, pharmaceutical machinery, petrochemical industry, electroplating and coating, and other control systems. Working principle of 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 half-upper pilot valve , after the pilot valve is closed, the main valve is closed by the pressure difference. Normally closed: When the coil is powered on, the pilot spool is closed, the pilot hole is opened, the pressure on the valve is relieved, the piston is pushed by the medium pressure in the lower chamber, and the solenoid valve opens;when the coil is powered off, the pilot spool is reset by the spring, and the pilot hole is When the valve 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. Normally open: When the coil is energized, the pilot hole is closed, the upper cavity 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. Structural features of high temperature solenoid valve 1. Reasonable selection of wear-resistant materials. The valve cup and guide sleeve cleverly utilize the lubrication effect of fluid to reduce wear and extend service life. 2. The condensate water in the condensation-resistant steam pipeline is an important factor affecting the action of the steam solenoid valve, but this valve is not affected by the condensate water. 3. The heat-resistant electromagnetic part and the seal part are made of special high-temperature resistant electrical materials and sealing materials, and various heat insulation measures are applied. The above is the working principle of high-temperature solenoid valve, and the function and application content of high-temperature solenoid valve are introduced.
