Description

Technical Field

[0001] The utility model relates to the technical field of valve regulators, in particular to a valve regulator used for liquid dispensing processing. Background Art

[0002] Liquid preparation is a complex process involving multiple industries and fields. It requires different chemical substances to be mixed together in specific proportions and methods to achieve the expected product quality or process requirements. Valves are control components in fluid delivery systems and have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. When performing liquid preparation, it is usually necessary to adjust the opening of the pipeline valve through a valve regulator to ensure the proportion of the liquid preparation.

[0003] Existing valve regulators regulate the proportion of liquid preparation by controlling the valve opening. This process usually requires a high degree of accuracy and control to ensure the quality of the final product. However, when the valve opening is reduced, the water pressure will temporarily increase, increasing the water flow rate and the water volume. This cannot ensure the accurate amount of various raw materials used in the liquid preparation process, which will affect the quality of the liquid preparation.

[0004] Therefore, it is urgent to provide a valve regulator for liquid preparation processing to solve the above problems. Utility Model Content

[0012] The present invention is further configured as follows: the anti-backflow mechanism includes an anti-backflow pipe fixed to the left end of the manifold, and an anti-backflow adapter is fixedly installed on the left end of the anti-backflow pipe.

[0031] like Figure 2 and Figure 4 As shown, a reflux mechanism 3 is provided on the top of the square valve body 1. The reflux mechanism 3 includes a telescopic shell 301 fixed to the top of the square valve body 1. A second electric telescopic rod 302 is fixedly installed on the top of the telescopic shell 301. One end of the piston rod of the second electric telescopic rod 302 is fixedly installed with a reflux pipe 303 with one end passing through and extending into the interior of the telescopic shell 301. The second electric telescopic rod 302 drives the reflux pipe 303 to rise and fall, and refluxes the flow that needs to be regulated by the valve regulator. A reflux sealing ring 304 is fixedly installed on the bottom end of the reflux pipe 303. The outer surface of the reflux sealing ring 304 is sealed with the inner wall of the telescopic shell 301. The reflux sealing ring 304 seals the four sides of the reflux pipe 303. A manifold 305 is fixedly installed on the left end of the reflux pipe 303.

[0032] like Figure 2 and Figure 5As shown, an anti-backflow mechanism 4 is provided on the left side of the reflux mechanism 3. The anti-backflow mechanism 4 includes an anti-backflow pipe 401 fixed to the left end of the manifold 305.

The reflux flow returns to the raw material tank through the manifold 305, the anti-backflow pipe 401 and the anti-backflow adapter 402. The inner cavity of the anti-backflow pipe 401 is fixedly installed with a mounting frame 403. Two mounting shells 404 are fixedly installed at the bottom of the mounting frame 403.
