Description

Technical Field

[0001] This utility model relates to an adjustable flow PGA solenoid valve, belonging to the technical field of PGA solenoid valves. Background Technology

[0002] PGA solenoid valves are valves that use an electromagnetic coil to drive the valve core. When the coil is energized, the generated electromagnetic force pushes the valve core to move, opening or closing the flow channel. After the power is cut off, the valve core is reset by a spring, achieving efficient and rapid automatic shut-off. PGA solenoid valves are one of the valves used in garden irrigation equipment.

[0003] However, existing PGA solenoid valves can only open and close, and cannot effectively regulate and control the flow rate, making it difficult to achieve low-flow drip irrigation for garden irrigation using PGA solenoid valves. To address the above shortcomings, this utility model proposes a PGA solenoid valve with adjustable flow rate. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable flow PGA solenoid valve to solve the existing problems.

[0006] The flow regulation mechanism includes an adjustment seat, and an adjustment core assembly is horizontally fitted inside the adjustment seat cavity. An observation window for viewing the adjustment of the adjustment core assembly is fitted on the front side of the adjustment seat. A first sealing ring is embedded on the top surface of the adjustment seat for pressing and sealing against the upper edge of the water outlet.

[0007] A further improvement is that the adjusting seat is composed of a vertical seat and a horizontal seat integrated together. The top surface of the vertical seat has a water inlet channel in the middle. The front side of the horizontal seat has a square adjusting groove that communicates with the water inlet channel. The four sides of the square adjusting groove have arc-shaped surfaces. The rear end of the right groove wall of the square adjusting groove has an observation window opening. The bottom of the square adjusting groove is connected to the water inlet channel with a water outlet pipe. The top surface of the vertical seat has a sealing ring around its perimeter.

[0008] A further improvement is that the adjusting core assembly includes a fixed base, on which a bearing and an adjusting screw are nested laterally. The right end of the adjusting screw is threadedly connected to a core for sliding left and right in a square adjusting groove, and a second sealing ring is fitted around the core to seal against the groove wall of the square adjusting groove.

[0009] A further improvement is that the observation window is composed of a sealing plate and a sleeve, the observation window is made of transparent material, a third sealing ring is fitted on the rear side of the sealing plate, and a scale is provided on the surface of the sealing plate.

[0010] A further improvement is that the PGA solenoid valve body is existing technology, and its structure will not be described in detail here.

[0012] This utility model provides an adjustable flow PGA solenoid valve. The flow adjustment mechanism, consisting of an adjusting seat, adjusting core assembly, observation window, and a first sealing ring, is connected and sealed to the lower end of the PGA solenoid valve body, thus creating an adjustable flow PGA solenoid valve. The valve body can still perform efficient and rapid automatic shut-off. The flow rate of the PGA solenoid valve body can be adjusted through the simple operation of the flow adjustment mechanism.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1-5The present invention discloses a schematic diagram of a PGA solenoid valve with adjustable flow rate. The structure includes a PGA solenoid valve 1, which comprises a PGA solenoid valve body 11. A water inlet pipe 12 is connected to the top surface of the PGA solenoid valve body 11, and a water outlet 13 is connected to the lower end of the PGA solenoid valve body 11. A flow rate regulating mechanism 2 is sealed within the water outlet 13. The flow rate regulating mechanism 2 includes an regulating seat 21, and a regulating core assembly 22 is horizontally fitted inside the cavity of the regulating seat 21. An observation window 23 is fitted on the front side of the regulating seat 21 for viewing the regulating core assembly 22 during adjustment. A first sealing ring 24 is embedded on the top surface of the regulating seat 21 for pressing and sealing against the upper edge of the water outlet 13.

[0020] The adjusting seat 21 is integrally formed by a vertical seat 211 and a horizontal seat 212. A water inlet channel 213 is provided in the middle of the top surface of the vertical seat 211. A square adjusting groove 214 communicating with the water inlet channel 213 is provided on the front side of the horizontal seat 212. Arc-shaped surfaces 215 are provided on the four sides of the square adjusting groove 214. An observation window opening 216 is provided at the rear end of the right groove wall of the square adjusting groove 214. A water outlet pipe 217 is connected to the bottom of the square adjusting groove 214 at the position aligned with the water inlet channel 213. A sealing ring edge 218 is provided around the top surface of the vertical seat 211.

[0021] The adjusting core assembly 22 includes a fixed base 221, on which a bearing 222 and an adjusting screw 223 are nested laterally. The right end of the adjusting screw 223 is threadedly connected to a core 224 for sliding left and right in a square adjusting groove 214. A second sealing ring 225 is fitted around the core 224 to seal against the groove wall of the square adjusting groove 214.

[0022] The observation window 23 is integrally formed by a sealing pressure plate 231 and a sleeve block 232. The observation window 23 is made of transparent material. A third sealing ring 233 is fitted on the rear side of the sealing pressure plate 231. A scale 234 is provided on the surface of the sealing pressure plate 231.

[0023] Working principle:

[0024] In use, the PGA solenoid valve body 11 is energized in a conventional manner to achieve full opening for flow or full closing for flow interruption. The specific principle is existing technology and will not be elaborated on here.

[0025] When adjusting the flow rate of the PGA solenoid valve 1, the adjusting screw 223 is rotated. Because the adjusting screw 223 and the core 224 are connected by a thread, the core 224 will slide left and right within the square adjusting groove 214. When the core 224 slides to the left, the flow rate increases, and when it slides to the right, the flow rate decreases. The movement of the core 224 within the square adjusting groove 214 can be observed through the observation window 23. The observation window 23 is made of transparent material, allowing the user to accurately and quickly adjust the flow rate of the PGA solenoid valve body 11 through the simple operation of the flow adjustment mechanism 2.
