High temperature solenoid valve description, high temperature water solenoid valve characteristics

Solenoid valve for high temperature water Description:
The solenoid valve with high temperature water diameter 15 ~ 100 is a pilot solenoid valve with diaphragm type for secondary opening valve, and the pilot solenoid valve with diameter 125 ~ 300 is a pilot solenoid valve with three times opening valve, and its structure is mainly composed of auxiliary valve and main valve.
According to the different switching state at the time of power failure, it can be divided into normally closed solenoid valves and normally open solenoid valves. Normally closed solenoid valve, when in normal position, the movable iron core seals the auxiliary valve port, the pressure in the valve chamber is balanced, and the auxiliary valve and the main valve port are closed. When the coil is energized, the electromagnetic force is generated to attract the movable iron core, the auxiliary valve is opened, and the medium self-guiding valve in the main valve chamber is leaked, so that the pressure difference between the upper and lower parts of the main valve cup is generated, the diaphragm or the valve cup is quickly lifted, the main valve port is opened, and the valve is in a path state.
When the coil is powered off, the magnetic field disappears, the active iron core is reset, the secondary closure is closed, and the pressure in the valve cup of the secondary valve and the main valve rises, the valve cup of the main valve is pressed to the seat, and the valve is closed again.
Normally open solenoid valve, when the coil is energized, the magnetic force is generated, and the armature moves down under the magnetic force, pushing the auxiliary valve cup down, and the auxiliary valve is closed. As the pressure difference between the upper and lower valve cups of the main valve tends to be equal, the main valve cup is closed from the self-pressure to the sealing surface. When the coil is powered off, the magnetic force is zero, the armature and the auxiliary valve cup rise due to the action of the spring, the auxiliary valve opens, the medium in the main valve cup flows away through the auxiliary valve, and the pressure drops. When the pressure drops to a certain value, the main valve valve cup rises upward due to the effect of the upper and lower pressure difference, the main valve opens, and the valve opens.
There are many kinds of solenoid valves for high temperature water, and in the production, the relevant departments should carry out strict checks and monitoring. Ensure its quality is effectively guaranteed. Solenoid valves for high temperature water valves are indispensable for fluid control in various sectors of the national economy such as petroleum, chemical industry, power stations, long-distance pipelines, shipbuilding, nuclear industry, various low-temperature engineering, aerospace and offshore oil production. The development and needs of industry have promoted the development of the valve industry. In recent years, while meeting the new requirements of high parameters in all aspects, close attention has also been paid to the structure, materials and production process of the valve, and how to better improve performance, feasibility and reduce costs.
Characteristics of high temperature water solenoid valve:
Normally open solenoid valve can be used bistable solenoid valve, the other case is the solenoid valve temporarily opened temporarily closed. That is, the power is off after the solenoid valve is powered on. At this time, the solenoid valve persists in the open state. When it is closed, the solenoid valve needs to be powered again before it is closed.
The solenoid valve is opened after the coil is powered off, and the normally open solenoid valve is characterized by: the solenoid valve is closed when the coil is powered on. The solenoid valve in the pipeline is open for a long time, and the normally open type should be selected when it is closed occasionally.
The solenoid valve for high temperature water can be prevented by the control module from overheating and burning the normally closed solenoid valve coil.
