Problems solved by technology
On the one hand, the increase in the area of the two will lead to an increase in manufacturing costs, and on the other hand, it is not conducive to the miniaturization of the structure.
In addition, with the increase of the area of the two, when the piston part 3' closes the main valve port 1'3, the leakage of the two will increase, thus reducing the sealing performance between the two

Embodiment Construction
[0033]The core of the present invention is to provide a pilot-operated solenoid valve. The structural design of the solenoid valve enables the fluid to have a small flow resistance when flowing under the same caliber, so that the relatively small main valve port can be used to obtain all The required flow rate can reduce the manufacturing cost and make the structure miniaturized. Or the main valve port of the same size can obtain lower pressure loss and improve the energy efficiency of the system. In order to facilitate the manufacture and make the design of the flow channel of the fluid reasonable, the electromagnetic valve of the present invention includes a main valve body part, which includes a main valve body and an inner valve seat, which are combined to form a main valve body assembly. The two are processed and manufactured separately, the manufacturing process is relatively simple and convenient, and the main valve body and the inner valve seat are combined to form the...

The invention discloses a solenoid valve and in particular discloses a large-caliber piloted solenoid valve. The solenoid valve is provided with a fluid inlet and a fluid outlet and comprises main valve body components, wherein the main valve body component comprises a hollow main valve body and an inner valve seat arranged in the main valve body; the inner valve seat is fixed on the main valve body; the inner valve seat is provided with a piston cavity; and a main valve body component flow channel communicated with the fluid inlet is also arranged between the inner wall of the main valve body and the circumferential side wall of the inner valve seat. The solenoid valve has the following beneficial effects: the main valve body and the inner valve seat are combined to form the main valve body component; the solenoid valve is convenient to machine and has low manufacturing cost; and such a flow channel structure design ensures that the fluid has smaller flow resistance during flowing, thus the required flow can be obtained by using the relatively small main valve port and further, the manufacturing cost is lowered and the structure is miniaturized.
Description
technical field [0001] The invention relates to a flow control component, in particular to a pilot solenoid valve for controlling the flow of fluid refrigerant in the technical field of refrigeration. Background technique [0002] In the field of refrigeration technology, the solenoid valve is the refrigerant flow control part of the refrigeration equipment. Its working process is generally as follows: with the power on or off of the coil, the solenoid valve is opened or closed in the refrigeration equipment system such as air conditioners, thereby controlling the circulation of the refrigerant. and interrupt. Of course, the scope of application of the solenoid valve is not limited to the above-mentioned refrigeration technology field, for example, it is also widely used in the hydraulic field. Some large-diameter solenoid valves generally adopt pilot control, that is, two-stage or multi-stage valve opening control. [0003] Please refer to figure 1 and figure 2 , figu...
