A combined waste water valve

Abstract

The invention provides a combined waste water valve and belongs to the technical field of valve manufacture, aiming at solving the problem of poor water stability of an existing reverse osmosis water purifying mechanism. The combined waste water valve comprises a valve base and a valve cover, wherein the valve seat is connected with a water inlet pipe, a first water outlet pipe and a second water outlet pipe; the valve cover is internally provided with a pair of coils; the inner end, located in the valve seat, of the first water outlet pipe has a small channel; a sealing clapboard is arranged between the valve seat and the valve cover; the valve seat, the valve cover and the sealing clapboard are fixedly connected by fasteners; one side of the sealing clapboard is fixedly connected with two mounting pillars; the mounting pillars stretch into the corresponding coils; the mounting pillars have mounting chambers; the mounting chambers are internally provided with push rods and springs; the push rods can enable the first water outlet pipe to realize high flux flushing or small flow water circulation under the action of the coils and the springs; and the push rod can enable the second water outlet pipe to open or close under the action of the coils and the springs. The combined waste water valve has the advantage of being capable of improving the water stability of the reverse osmosis water purifying mechanism.

Description

technical field [0001] The invention belongs to the technical field of valve manufacturing and relates to a combined waste water valve. Background technique [0002] The reverse osmosis pure water machine is a device that integrates microfiltration, adsorption, ultrafiltration, reverse osmosis, ultraviolet sterilization, ultra-purification and other technologies to directly convert tap water into ultra-pure water, which can be directly drunk after conversion. [0003] The reverse osmosis pure water machine is a relatively mature pure water manufacturing technology. The existing reverse osmosis pure water machine, such as a reverse osmosis pure water machine with a concentrated water adjustment controller declared by the applicant in January 2015 [Application number: 201510051391.4; Application publication number: CN 104609506 A], the regulating controller is located between the concentrated water end of the reverse osmosis membrane filter and the water storage pressure tank,...

AI Technical Summary

Problems solved by technology

[0004] The reverse osmosis pure water machine with this structure can increase the water production speed by setting the adjustment controller, reduce the discharge of concentrated water, and reduce the waste of water resources; however, the reverse osmosis pure water machine with this structure needs the slider to automatically feel the two The pressure difference at the end, through the pressure difference overcomes the elastic force of the spring, the slider moves left and right to change the flow area of ​​the water hole. During the flow, storage and discharge of the medium in the reverse osmosis pure water machine, the pressure difference is always changing, and the slide The block has been moving left and right, the adjustment is frequent, the fluctuation is large, and the water hole is clogged, and the stability is poor; and when there is a lot of scale and pollutants condensed on the filter, the only way to replace the filter or take it out Lower the filter for cleaning, and the cost of replacing the filter is high, but remove the filter for cleaning, after the cleaning is completed, it needs to be reinstalled, which is very troublesome
