Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valves, and more specifically to an electromagnetic stop valve body and a stop valve and an air conditioning system applied thereto. Background Art

[0002] Combination Figure 1 and Figure 2 As shown, in order to prevent flow limitation, the diameter of through hole A inside the solenoid valve body needs to be kept at 4 mm. However, due to the limited space inside the valve cavity, the burrs generated at the opening of through hole A during the drilling process cannot be removed by the machining center tool, and manual deburring is required. This increases the labor intensity and labor costs, and there is a risk of incomplete burr removal. If the burrs enter the air-conditioning system, the throttle hole may be blocked or partially blocked, resulting in a decrease in the air-conditioning cooling effect or failure to work properly. In addition, the solenoid valve is prone to refrigerant impact noise during power failure and opening and closing. Summary of the invention

[0003] The utility model aims to solve one of the technical problems in the related art to a certain extent. To this end, the utility model proposes a solenoid stop valve body.

[0004] The utility model also provides an electromagnetic stop valve using the valve body;

[0005] The utility model also provides an air conditioning system using the valve body.

[0006] The technical solution adopted by the utility model is: to provide an electromagnetic stop valve body, wherein a through hole and a pillow-type flow channel are provided in the valve cavity of the valve body, the pillow-type flow channel is a groove milled from the bottom of the valve cavity, and the pillow-type flow channel covers the orifice of the through hole.

[0007] Compared with the prior art, the above structure has the following advantages:

[0008] 1. After the through hole drilling is completed, the pillow-type flow channel is processed by a milling cutter, and the processing is completed in one step by the machining center. Since the milling path of the pillow-type flow channel passes through the through hole, the edge of the hole is repaired and smoothed, and there is no need to manually repair burrs.

[0009] 2. During use, the inventor found that the reason why the solenoid valve produces abnormal noise during power-off and opening and closing is that the angle of the refrigerant flow channel is too large, that is, the angle between the through hole opening and the valve cavity is a vertical angle. In this application, by setting a transition structure of a pillow-type flow channel, the flow channel angle is improved, the refrigerant impact is reduced, and the abnormal opening and closing noise when the valve is powered off is improved.

[0010] According to an embodiment of the utility model, the pillow-type flow channel is fan-shaped.

[0011] According to an embodiment of the utility model, the through hole opening is located on the center line of the sector.

[0012] According to an embodiment of the present invention, the diameter of the through hole is R1, the outer diameter of the pillow-type flow channel is R2, and the inner diameter is R3, and R2-R3≥R1.

[0013] According to an embodiment of the present invention, the groove depth of the pillow type flow channel gradually decreases along the direction from the through hole opening to one end or both ends of the pillow type flow channel.

[0014] According to an embodiment of the utility model, a central hole is provided in the valve cavity.

[0015] According to an embodiment of the utility model, the pillow-type flow channel is arranged concentrically with the center hole.

[0016] An electromagnetic stop valve comprises any valve body described above.
