Small and medium-sized high-pressure solenoid valves are improved from most of the small and medium-sized low-pressure solenoid valves.
The working chemicals of high-pressure solenoid valves are generally N2, helium, xenon, compressed natural gas (such as NH3) and so on. The basic principle is: when the electromagnetic coil is plugged in, the electromagnetic coil causes sufficient magnetic field force to solve the elasticity and chemical substance pressure, so that the controller flows the coil exercise, the shut-off valve is opened, and the electromagnetic valve manufacturer works by the shut-off valve. The safe passage of the flow coil goes through the overcurrent passage on the flow coil, which is discharged from the middle and upper reaches. When the electromagnetic coil is de-energized, the magnetic field force is dissipated, and the flow coil is corrected under the action of the elastic force and the pressure of the chemical substance, and returns to the closed position, resulting in airtightness , To cut off the circulation of chemical substances.
Principles and characteristics of small high-pressure solenoid valves:
Small and medium-sized high-pressure solenoid valve is a traditional solenoid valve for solenoid heat exchanger normally closed. It adopts a compact single solenoid, single high-pressure gate valve, torsion spring, full arc welding and electric welding structure. The professionalism of the small high-pressure solenoid valve has been improved in many ways from the perspective of miniaturization, and the working pressure of the shut-off valve has been further increased in most of the small and medium-sized low-pressure solenoid valves. The small high-pressure solenoid valve has a simple structure and a lighter net weight. , Small size, low output power, quick recovery, and wide working pressure coverage.
The main features of small and medium-sized high-pressure solenoid valves are quick recovery, small and medium-sized, and high compressive strength. In most of the original design schemes of small and medium-sized low-pressure solenoid valves, some essential modifications have been made, such as the expansion current Magnetic effect adsorption for quick response of solenoid valve; simple structure to ensure miniaturization, etc.
It is convenient for the solenoid valve to ensure rational characteristics and take into account the specifications, model, net weight, characteristics and other requirements. In the design of small high-pressure solenoid valves, it is important to select from the improvement of raw materials and basic parameters, and to carefully arrange the structural specifications and models of the solenoid valve manufacturer. The reasonable formulation of the processing technology and other aspects have carried out the structural design optimization of the structure and characteristics of each prefabricated component of the solenoid valve.
Due to the contradiction between the extraordinary characteristics of medium and small high-pressure solenoid valves and the microminiaturized structure, in all design schemes, small high-pressure solenoid valves should be controlled according to strict design schemes and continuous system testing as far as possible. The volume of the valve design scheme ensures the miniaturization and extraordinary characteristics of the solenoid valve.
