Example Embodiment

[0026] The present invention is suitable for solenoid valves that are closed when energized. For example, it is suitable for solenoid valves that are directly closed when energized and indirectly closed through a pilot type. When the flow rate of the solenoid valve is relatively small, the structure of direct opening and closing is generally adopted. When the solenoid valve requires a relatively large flow rate, a pilot-type indirect opening and closing structure is adopted; from the two structures, the pilot-type indirect opening and closing structure is relatively complicated, and the working principle of the two is the same. For this reason, a solenoid valve that uses a pilot type to achieve indirect closing is described in detail below.

Abstract

The invention discloses an electromagnetic valve closed in an electrified state, which comprises a valve body part and a coil part, wherein a movable iron core part and a fixed ion core component are arranged in the valve body part. The electromagnetic valve is characterized in that: the fixed ion core component comprises a fixed part which is immobilized axially and a moveable part which can move axially and relatively; and an offsetting spring is arranged between the fixed part and the moveable part which can rotate axially and relatively. The electromagnetic valve closed in the electrifiedstate belongs to the technical field of refrigeration control. After the electromagnetic valve of the invention is used, an assembly process is relative simple, the offsetting spring avoids an electromagnetic loop, the magnetic loop is rationally designed, and thus, the stability and reliability of the electromagnetic valve can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of refrigeration control, and is especially suitable for the control of pipelines of refrigeration systems such as refrigeration equipment and commercial air conditioners. In particular, it relates to a solenoid valve structure that is closed when energized. Background technique [0002] Solenoid valves for pipeline opening and closing are widely used in the circuit of refrigeration systems. Generally, solenoid valves are opened when energized, and some pipelines are closed when energized, which is more energy-saving and suitable. There are generally two kinds of electromagnetic valves that are energized and closed. One is the electromagnetic valve disclosed in the Chinese utility model patent whose patent application number is 03231177. One kind of solenoid valve adopts the working mode of direct opening and closing, and the flow rate of the general solenoid valve is relatively small; while the one for the...
