Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of switch valve, in particular to a production method of electromagnetic switch valve and the electromagnetic switch valve. BACKGROUND

[0002] The switch valve is a mechanical device for controlling the on-off of fluid (liquid, gas, etc.), which realizes the opening or closing of the pipeline through the movement (such as rotation, sliding) of the valve core, and is widely used in oil circuit, gas circuit, cooling liquid circuit and other systems.

[0003] The electromagnetic switch valve is a switch valve directly controlled by the electromagnetic coil to open or close. The electromagnetic switch valve includes a valve body, a valve core, an electromagnetic coil, a moving iron core and a return spring. The valve body is provided with a fluid passage, an inlet, an outlet and a valve port. The valve core is rigidly connected with the lower end of the moving iron core or made in one piece. When the electromagnetic coil is de-energized, the thrust of the return spring closes the valve port together with the moving iron core and the valve core, thereby closing the flow passage. When the electromagnetic coil is energized, the moving iron core overcomes the thrust of the return spring and drives the valve core to move, thereby opening the valve port and opening the flow passage.

[0004] Since the moving iron core and the valve core are currently in one piece, when the electromagnetic switch valve is used for a long time, the moving iron core is prone to axial deviation during movement, thereby causing the valve core to have axial deviation, resulting in uneven adhesion of the valve core to the valve port, which easily leads to failure of the electromagnetic switch valve. SUMMARY

The valve seat 4 is provided with a communication hole 5 along the length direction of the valve body 1, so that after the fluid enters from the fluid outlet 3, it enters the cavity of the valve body 1 through the communication hole 5, and then flows out from the fluid outlet 3 after flowing through the gap outside the valve seat 4.

[0117] The size reduction ratio refers to the reduction ratio required for the placement and installation of the electromagnetic on-off valve. The size reduction ratio is obtained by being preset by the operator according to actual needs.

[0118] S23: Determine the internal capacity value according to the fluid flow value.

[0119] The internal capacity value refers to the total volume quantitative index corresponding to the cavity and flow passage inside the electromagnetic on-off valve for fluid circulation.

[0120] The product value between the fluid flow value and the preset reasonable residence time of the fluid in the valve is calculated, and the calculation result is taken as the internal capacity value, which is convenient for subsequent use.

[0121] S24: Determine the execution specification parameter by combining the external size parameter and the internal capacity value.

The execution specification parameter includes the size specification parameter of the valve body 1 and the valve seat 4.

[0123] The length and width dimensions of the valve body 1 are determined by the external size parameter, and the cavity volume and flow passage volume between the valve body 1 and the valve seat 4 and the height dimension of the valve body 1 are determined by the internal capacity value. The overall contour size corresponding to the symmetrical installation of the valve body 1 and the valve seat 4 is obtained by setting the symmetry standard between the valve seat 4 and the valve body 1, and is taken as the execution specification parameter, which is convenient for subsequent use.

[0124] S25: Determine the related specification parameter according to the execution specification parameter.

[0125] The related specification parameter refers to a set of auxiliary component quantitative indexes that adapt to the overall function of the electromagnetic on-off valve.

[0127] The related specification parameter is determined by analyzing the execution specification parameter, which is convenient for subsequent use.

[0128] In order to further ensure the rationality of the relevant specification parameters, further separate analysis and calculation of the relevant specification parameters are required, which will be described in detail through the following steps.

[0129] The determination method of the relevant specification parameters comprises the following steps:

The coil specification parameters refer to the length, width, and height size parameters of the electromagnetic coil 9. The core specification parameters refer to the length, width, and height size parameters of the moving iron core 10.

[0134] The length and width dimensions of the valve cover 12 and the electromagnetic coil 9 are determined by calling the top external dimensions of the valve body 1 through the external specification parameters, and the height dimension of the electromagnetic coil 9 is calculated by calculating the product value between the height dimension of the valve body 1 and the preset height dimension ratio. The remaining height is obtained by combining the height in the external dimension parameter and the height in the external specification parameter, and is taken as the height of the valve cover 12. The length, width, and height dimensions of the valve cover 12 are combined to obtain the cover specification parameters.
