Problems solved by technology

[0011] However, during soldering, the above-mentioned structure cannot fully use the wire feed gun to automatically feed the solder, and the solder needs to be manually fed in. Because of manual differences, the product quality fluctuates, and the labor cost is high, which increases the production cost of the product.

Embodiment 1

[0076] Please refer to Figure 8-1 to Figure 8-3 ;in, Figure 8-1 It is a sectional view of the first small valve seat of the pilot valve body part provided by the present invention; Figure 8-2 and Figure 8-3 respectively Figure 8-1 left and top views.

[0077] In this embodiment, the small valve body 42 has a small valve seat hole for assembling the small valve seat 41, and the small valve seat 41 has a capillary e hole 411, a capillary s hole 412, and a capillary c hole for respectively assembling the capillary e, the capillary s, and the capillary c. 413.

[0078] Wherein, the first weld H1 is formed between the outer peripheral wall of the small valve seat 41 and the inner wall of the small valve seat hole, the second weld H2 is formed between the outer peripheral wall of the capillary e and the inner wall of the capillary e hole 411, and the outer periphery of the capillary s A third weld H3 is formed between the wall and the inner wall of the hole 412 of the capi...

Embodiment 2

[0096] Please refer to Figure 9-1 to Figure 9-3 ;in, Figure 9-1 It is a sectional view of the second small valve seat of the pilot valve body part provided by the present invention; Figure 9-2 for Figure 9-1 The left section view of the small and medium valve seat at the capillary s hole; Figure 9-3 for Figure 9-1 top view.

[0097] Compared with the first embodiment, in this embodiment, the communication structure only includes a communication groove 41 f , which connects the capillary e hole 411 , the capillary s hole 412 and the capillary c hole 413 .

[0098] In the specific solution, the structure of the communication groove 41f is consistent with the aforementioned first embodiment, that is, the communication groove 41f is provided with two straight grooves, one of which communicates with the capillary e-hole 411 and the capillary s-hole 412, and the other communicates with the capillary s hole 412 and capillary c hole 413, thus, the second weld H2, the third ...

Embodiment 3

[0103] Please refer to Figure 10-1 to Figure 10-3 ;in, Figure 10-1 It is a sectional view of the third small valve seat of the pilot valve body part provided by the present invention; Figure 10-2 for Figure 10-1 The left section view of the small and medium valve seat at the capillary s hole; Figure 10-3 for Figure 10-1 top view.

[0104]Compared with the first embodiment, in this embodiment, the communication structure also includes a communication groove 41 f, which connects the capillary e hole 411 , the capillary s hole 412 and the capillary c hole 413 .

[0105] In a specific solution, the structure of the communication groove 41f is consistent with that of the aforementioned first embodiment, and will not be repeated here.

[0106] The difference from the first embodiment is that the upper end of the small valve seat 41 is provided with a stepped portion 41a facing upwards, and the stepped portion 41a penetrates the capillary e hole 411 and the capillary c hol...

Abstract

The invention discloses a guide valve component comprising a small valve body having a small valve seat hole and a small valve seat. The small valve seat is provided with a capillary e hole for assembling a capillary e, a capillary s hole for assembling a capillary s and a capillary c hole for assembling a capillary s; a welding joint is formed between the peripheral wall of the small valve seat and the inner wall of the small valve hole is formed; a welding joint is respectively formed between the peripheral wall of each capillary and the inner wall of each capillary hole; a communication structure is formed in the small valve seat; and at least two welding joints are communicated via the communication structure. Therefore, manual solder conveying work can be replaced via an automatic way, so quality difference due to manual work can be avoided and quality stability of the guide valve component can be improved and production cost can be reduced; and on the basis, the invention further provides a guide valve containing the guide valve body component and a four-way reversing valve.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a pilot valve body component, a pilot valve and a four-way reversing valve with the pilot valve body component. Background technique [0002] The four-way reversing valve is mainly used in heat pump air conditioners, water heaters and other systems to realize the switching of refrigerant flow channels in the system, and then realize the cooling and heating functions of the entire system. [0003] Please refer to figure 1 , figure 1 It is an assembly schematic diagram of a four-way reversing valve in the prior art. [0004] The existing four-way reversing valve mainly consists of an electromagnetic coil 30 , a pilot valve 20 and a main valve 10 . [0005] When working, the pilot valve 20 changes the refrigerant outflow direction under the electromagnetic action of the electromagnetic coil 30 on and off, and the change of the refrigerant outflow direction inside the pilot ...
