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
[0034] 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.
[0035] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0036] Please refer to image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 ,in image 3 It is a front sectional view of a pilot-operated solenoid valve in an embodiment of the present invention, Figure...

The invention discloses a solenoid valve and particularly discloses a pilot-operated solenoid valve with a large caliber. The pilot-operated solenoid valve is provided with a fluid inlet and a fluid outlet; the solenoid valve comprises a main valve body assembly (1), wherein the main valve body assembly (1) comprises a hollow main valve body (11) and an inner valve seat (12) which is located in a hollow cavity of the main valve body (11); the inner valve seat (12) is provided with a piston containing cavity (122); the solenoid valve further comprises an outlet valve body assembly (7) which is fixedly matched with the main valve body assembly (1); the outlet valve body assembly (7) is provided with a main valve opening (73) and a piston component (5) is arranged on the main valve opening (73) relative to the outlet valve body assembly (7). According to a structural design of a flow channel of the solenoid valve, the fluid has a smaller flow resistance in a flowing process, so that the needed flow can be obtained by using the relatively smaller main valve opening; and therefore, the manufacturing cost is reduced 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...
