Three-port one-way valve for direct drinking water purifier

Abstract

The invention discloses a three-port one-way valve for a direct drinking water purifier, and belongs to the field of one-way valves. The three-port one-way valve for a direct drinking water purifier is characterized in that through arranging a bidirectional elastic half ball, a one-way valve and a three-port valve are mutually combined to form a three-port one-way valve, thus achieving the effectthat only one valve is required to control two water discharging manners of the direct drinking water purifier. In this way, the investment cost of water purifiers can be reduced, and meanwhile, compared with the prior art, two valves reduce to one, thus reducing cleaning workload of disinfecting, sterilizing and the like of the interior of a valve body; in addition, through arranging a reversiblemicro deformation protecting layer on threads between a valve rod and the valve body and a valve rod semi-hollow structure, not only the treads are prevented from being worn and rusted but also lubricating oil can be timely added into the valve rod, thus effectively reducing problems of high exhaust gas rate and low utilization rate caused by the jamming occurring between the valve rod and the valve body.

Description

technical field [0001] The invention relates to the field of one-way valves, in particular to a three-way integrated one-way valve used for direct drinking water purifiers. Background technique [0002] Generally, the water purifier has two water inlets. The water purifier with two water inlets is RO reverse osmosis water purifier, one water inlet is purified water, and the other water inlet is pure water. The purified water is coarsely filtered by the pre-filter and before entering the RO membrane, the water has been coarsely filtered and adsorbed by activated carbon, the solid impurities in the water have been reduced to the minimum, and the residual chlorine content in the water has also been eliminated by more than half , suitable for washing vegetables, cooking soup and other purposes, and because there is no RO membrane, no waste water will be generated, and the water pressure is large enough to fully meet the general water requirements. Pure water is water filtered b...

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the object of the present invention is to provide a three-way integrated one-way valve for direct drinking water purifiers, which can connect the one-way valve and the three-way valve to each other through the setting of two-way elastic hemispheres. Combined to form a three-way integrated one-way valve, only one valve is needed to control the effect of two types of water from the water purifier. On the one hand, the cost of the water purifier is reduced. On the other hand, compared with the existing technology, two valves are used. It becomes a valve, which reduces the workload of cleaning the interior of the valve body after disinfection and sterilization. At the same time, the reversible micro-deformation protective layer on the thread between the valve stem and the valve body and the setting of the semi-hollow structure of the valve stem can Realize that while protecting the thread from wear and corrosion, it can also add lubricating oil to the valve stem in time, thereby effectively reducing the problems of high exhaust gas rate and low utilization rate caused by the stuck phenomenon between the valve stem and the valve body
