[0018] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0019] Figure 1 It is a cross-sectional view of the utility model; Figure 2 It is an exploded view of the present utility model.

[0020] Combined with attachment Figure 1 and attached Figure 2 As shown, a fluid mixing valve includes a mixing valve body 1, a mixing liquid outlet head 2, and a one-way valve 3. The mixing valve body 1 is provided with a flow channel 1 4, a flow channel 2 5, a liquid outlet 6, a curing agent liquid inlet 7, a glue liquid inlet 8, a solvent liquid inlet 9, and a water inlet 10. The flow channel 1 4 and the flow channel 2 5 are both connected to the liquid outlet 6. The mixing liquid outlet head 2 is installed on the liquid outlet 6. The curing agent liquid inlet 7 and the solvent liquid inlet 9 are connected to the flow channel 1 4, the glue liquid inlet 8 and the water inlet 10 are connected to the flow channel 2 5. Two one-way valves 3 are respectively located on the flow channel 1 4 and the flow channel 2 5.

[0021] The curing agent inlet 7 is connected to the curing agent valve through a pipeline, the glue inlet 8 is connected to the glue valve through a pipeline, the solvent inlet 9 is connected to the solvent valve through a pipeline, and the water inlet 10 is connected to the water valve through a pipeline.

[0022] The mixing valve body 1 includes a valve seat 11 and a tee 12, which are fixed together by bolts. The mixing liquid outlet head 2 is installed on the tee 12, and the curing agent inlet 7, glue inlet 8, solvent inlet 9, and water inlet 10 are all located on the valve seat 11.

[0023] The mixing liquid discharge head 2 includes a discharge nozzle 21, a stud 22, and a sealing ring 23. A liquid discharge channel is provided in the stud 22, a thread is provided on the inner wall of the liquid outlet 6, and a thread is provided on the outer wall of the discharge nozzle 21. The discharge nozzle 21 and the stud 22 are both threadedly connected to the liquid outlet 6. The flow channel 1 4 is connected to the liquid discharge channel in the stud 22, and the flow channel 2 5 is connected to the liquid outlet 6. The stud 22 is located in the discharge nozzle 21, and a sealing ring 23 is provided between the discharge nozzle 21 and the mixing valve body 1.

[0024] An air inlet 13 is provided in the mixing valve body 1, and the air inlet 13 is communicated with the flow channel 2 5. The air inlet 13 is connected to the air valve.

[0025] The portion of the discharge nozzle 21 located outside the liquid outlet 6 is connected to the spray gun through a liquid outlet pipe; the sealing ring 23 can improve the waterproof sealing between the discharge nozzle 21 and the tee 12.

[0026] The one-way valve 3 includes a one-way valve body 31, a spring 32, a plug 33, and a sealing ring 34. The inner cavity of the one-way valve body 31 is connected to the plug 33 through the spring 32. A sealing ring 34 is provided between the one-way valve body 31 and the mixing valve body 1. One end of the plug 33 is provided with a plug for blocking the passage inside the one-way valve body 31.

[0027] The one-way valve 3 is located between the valve seat 11 and the tee 12 and is a detachable hub for the outlets of flow channel 1 4 and flow channel 2 5. Flow channel 1 4 and flow channel 2 5 are located within the valve seat 11 and the tee 12.

[0028] When no fluid enters, the spring 32 uses its own tension to continuously apply a pulling force to the plug 33 toward the one-way valve body 31, allowing the plug of the plug 33 to block the passage within the one-way valve body 31. When fluid enters from one end of the one-way valve body 31, the liquid pushes the plug 33 outward, thereby opening the one-way valve 3. Finally, the fluid passes through the one-way valve 3 and the valve body, completing the color changing / cleaning / color mixing operation. When fluid is no longer supplied to the one-way valve 3, the spring retracts and pulls the plug 33 to re-block the passage within the one-way valve body 31, thus preventing the infiltration of mixed liquid, which could cause pipeline contamination and even affect the normal operation of the machine.

[0029] The working method of this application is as follows: when the curing agent valve and the glue valve are opened, the fluid will enter the flow channel 1 4 and the flow channel 2 5 through the curing agent inlet 7 and the glue inlet 8, and enter the stud 22 and the discharge nozzle 21 respectively through the two one-way valves 3. The two fluids will eventually mix and flow out in the discharge nozzle 21, and the one-way valve 3 can prevent the fluid from flowing back. In addition, the greater the pressure from above, the tighter the plug 33 will be blocked, preventing the liquid from flowing back and causing operational losses. In the working state, the solvent valve, air valve, and water valve are all closed; when the cleaning operation control is turned on, the solvent valve, air valve, and water valve will all be opened, while the curing agent valve and glue valve will be closed, thereby completing the cleaning operation.

[0030] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
