Abstract
The utility model discloses a valve body structure of an electromagnetic valve, which belongs to the field of a refrigeration fitting. The prior-art electromagnetic valve has a defect of easy damage at the valve body and the sealing plug. The valve body structure of the electromagnetic valve comprises the following components: the valve body, a coil, an iron core and the sealing plug. The valve body is provided with an inlet and an outlet. The inlet and the outlet are communicated with the inner chamber of the valve body. The upper end of the valve body is provided with the coil. The iron core is equipped in the inner chamber of the valve body. The coil is connected with the iron core and controls vertical movement of the iron core. The sealing plug is fixedly equipped at the bottom of the iron core. The bottom of the iron core is provided with a mounting groove in which a buffer device is mounted. The bottom of the buffer device is jointed with the sealing plug. Through equipping a buffer device between the lower end of the iron core and the sealing plug, the valve body structure of the electromagnetic valve has the following advantages: reducing impact between the sealing plug and the inner chamber wall of the valve body in valve closing, effectively protecting the valve opening and the sealing plug, and prolonging service life of the electromagnetic valve.
Description
Technical field
The utility model belongs to refrigeration accessory field, and is especially relevant with a kind of solenoid valve.
Background technique
The connected sum that the existing effect that is used for the solenoid valve of refrigeration system is the automatic pilot line of circuit is closed, solenoid valve comprises valve body, be positioned at the coil on the valve body and be positioned at the core iron of body cavity, valve body is provided with import and outlet and body cavity and connects, the lower end of core iron is provided with sealing plug, conduction by coil and outage control core iron drive sealing plug and move up and down, thus the control sealing plug between importing and exporting connection or close.Existing core iron is in the process of moving up and down because the sudden power of coil, this moment sealing plug because inertia, sealing plug can produce the internal chamber wall of valve body, can cause damage to valve body and sealing plug under long-time.
The model utility content
The purpose of this utility model is intended to overcome the valve body of existing solenoid valve existence and the defective that sealing plug is damaged easily, and a kind of electromagnetic valve body structure of valve body long service life is provided.
For this reason, the utility model is by the following technical solutions: a kind of electromagnetic valve body structure, comprise valve body, coil, core iron and sealing plug, valve body is provided with import and outlet, import and outlet and body cavity connect, the upper end of valve body is provided with coil, core iron is arranged in the body cavity, coil is connected with core iron, controls moving up and down of core iron, and sealing plug is fixedly installed in the bottom of core iron, it is characterized in that, the bottom of described core iron is provided with mounting groove, and damping device is installed in the mounting groove, and the bottom of damping device and sealing plug are fitted.
As to technique scheme replenish and perfect, the utility model also comprises following technical characteristics.
Described damping device is a spring.
The bottom of described sealing plug is tapered, and the body cavity wall is provided with and the corresponding v-depression of cone seal plug.
Use the utility model can reach following beneficial effect: the utility model is by being provided with damping device between core iron lower end and sealing plug; reduced the bump of sealing plug and body cavity wall when valve cuts out; thereby effectively protected valve port and sealing plug, improved the life-span of solenoid valve.
