Three-position and five-way angular valve and automatic watersupply treating system controlled it

Abstract

This invention is a three position and five way valve, its rotating electromagnetic iron rotor, five way rotary valve axis of rotation, and manual spanner engaged with those of the others, coaxial gyre, so, it can be used manually and automatically, and has advantaegs of small volume, low cost. It can replace the existing automatic control valve, is applicable to automatic control of small water treatment device. Three kinds of water treatment devices controlled by this valve; totally automatic household tap water treatment system can purify bath water and drinking water, bath water purifier doesn't need to change the filter element in ten years, and reloading period of drinking water purifier is prolonged to at least one time; water treatment device for removing heavy metals can remove plumbum, nickel and arsenic etc. several decades poisoning heavy metals, make sure the safety of users who live in polluted areas such as mineral etc.; bath water purifier not only useful for the health of human being, but also useful for hairdressing, for waste water treatment and recovery.

Description

Technical field: [0001] The invention relates to a valve and a tap water treatment system controlled by the valve, in particular to a three-position five-way rotary angle valve and a fully automatic tap water treatment system controlled by the valve. Background technique: [0002] The water purification treatment process is the process of removing or reducing harmful pollutants in water through physical, chemical and biological methods according to the pollution status of different water sources and the specific requirements of users for water quality. [0003] According to the law of immortality, the reduction of harmful substances in water will inevitably lead to the increase of harmful substances or the decrease of useful substances in the water purification medium. When the increase of harmful substances or the decrease of useful substances reaches a certain limit, the water purification medium will also be lost. Purification function. For example, granular activated ca...

Problems solved by technology

[0007] The inventor once disclosed a five-channel ball valve in the publication number CN1333185A Chinese patent application and US6149809 U.S. patent. This valve has the following disadvantages: one can only be manually controlled, and cannot be automatically controlled. It is extremely inconvenient to use; the second is that the valve core is spherical, and the inner cavity of the valve sleeve is cylindrical, and two upper and lower sealing sleeves must be added between the valve core and the valve sleeve to increase the volume of the valve body, and the processing of the spherical valve core is complicated. The accuracy is difficult to guarantee, which not only increases the cost, but also easily causes water leakage

[0012] First, the conversion between the three different working positions of the control valve can only be done electrically and cannot be controlled manually

There must be two potential risks in this way: one is that when any fault occurs in the automatic control valve, the system can only be shut down for repair; the other is that when the system is in the process of reverse flushing or forward flushing operation, it cannot be reset manually in the event of a power failure When you reach the water purification station, you can only close the water source and stop using water, otherwise it will cause a lot of drainage loss; second, the volume of the automatic control valve assembly cannot be miniaturized

The pipe arrangement type automatic control valve has a large number of parallel water flow conduits. In order to ensure sufficient flow, the pipe diameter cannot be very small, so the radial dimension of the valve body cannot be reduced. In order to avoid electromagnetic interference between the pipeline solenoid valves in adjacent water flow conduits , to ensure the reliable closing or opening action of the solenoid valve, and the axial dimension of the valve body cannot be shortened; the piston type automatic control valve, the actuator is driven by the rotary motion of the rotating motor and driven by the gear to pull the piston rod to complete the reciprocating linear motion along the axis of the valve body Therefore, the installation position of the rotating motor and its matching reducer, taking the valve body as the reference coordinate, the external teeth of the transmission gear must deviate from the corresponding distance from the end face of the valve body in the axial direction, and must deviate from the valve body in the radial direction. The corresponding distance from the central axis of the body, so the volume of the automatic control valve assembly can not be miniaturized

Third, the manufacturing cost is high

Such users have a professional operation and maintenance team, a reasonable reserve of maintenance spare parts, a dedicated water treatment plant, and the necessary purchase funds. Manual defects often go unnoticed

[0014] On the contrary, for ordinary families, small units, stores operating in special industries, and residents in areas with serious water pollution (mostly poor areas), they buy water purification products equipped with automatic control valves, because they do not know how to maintain them, and there is no maintenance Accessories, in the event of a power failure or failure of the automatic control valve, the water source can only be turned off and the water will be stopped; due to the limited indoor space, the water supply pipes are usually laid close to the ground, and the water purification equipment is very bulky. Water supply and drainage pipelines are erected in the air; the price of water purification equipment is very expensive, and the cost of use is too high, which is difficult for users to bear
