Description
Technical field
The present invention relates to drinking machine and manufacture field, especially a kind of Anti-leakage valve, refer to a kind of water route Anti-leakage valve being applicable to Household water treatment device especially.
Background technique
At present, the household water purifier on market, maximum hidden danger is exactly water route or joint percolating water, leaks and not only can waste valuable water resources, house decoration also can be caused to be destroyed, and cause great loss, is the most pain in the neck of manufacturer.A lot of manufacturer is also studying how to prevent seepage energetically, and investigated the device that some prevent seepage, but does not use in a large number for various reasons.
Leakage-resistant device has multiple: can control water route by electronic induction; Or by detecting water route variation in water pressure; Or buck booster water pump is set on water route; Or increase water-collecting bag etc. at the easy waterleakage part of product.
Electronic induction controls water route and is made up of two-part: a part is solenoid valve, for controlling main water route; Another part is leakage inspector.Leakage inspector generally comprises and is arranged at water channel bottom product and two induction terminals, and water channel is for collecting the water of seepage; When overboard phenomenon appears in equipment, when the induction terminal of two in water channel forms path, just can pass out water leakage, control the closed electromagnetic valve in main water route, thus cut off water route, reach waterproof effect.This mode is general in use at present, sensitive height, as long as there is percolating water, just can very quick closing valve water-blocking path, and well play preventing water leakage function; But complex structure, production and assembly difficulty is large, and price is high, generally uses on mid-to high-end product; This device sometimes in a humidity environment, there will be wrong report phenomenon.
Detect the method for water route variation in water pressure, be increase pressure switch on water route, control water route by the magnitude relationship of hydraulic pressure and pressure switch initial value.This controlling method sensitivity is very low, only has a large amount of to leak or after the leaking of long period, water route hydraulic pressure just can change, and pressure switch just can be made to close, thus play waterproof effect.This mode is easy to install, but sensitivity is low, and leaking on a small quantity and the percolating water of joint to water route, is generally difficult to detect.
Main water route is established buck booster water pump, the minimum hydraulic pressure that water route Stress control is used at one, water route water leakage phenomenon is produced when preventing hydraulic pressure excessive, but it is bad to water route assembling, and the percolating water of the joint caused can not detect and control, product still has the possibility of leaking.
Increase water-collecting bag at the easy leakage area of product, be collected by the water of seepage, be then directed to sewerage, house decoration can be protected like this not to be destroyed, but main water route does not turn off, water continues in leakage.Like this, still can cause the waste of great lot of water resources, meanwhile, have narrow limitation when such product is installed, the place being installed to sewerage be considered.

Working principle:
During Anti-leakage valve closed condition, the top entity part of core bar 2 was positioned at the left bottom of water channel 13, second seal ring 6 is in right low left high, the right side of the second seal ring 6 contacts with the right side inwall of valve body 1, the left side of the second seal ring 6 contacts with the top of the inner left wall of valve body 1, now cross water channel 13 blocked by core bar 2 and close, the positioning bar 22 on core bar 2 offsets with the positioning boss 81 of valve closed condition side on locating piece 8.When needing to open Anti-leakage valve, core bar 2 rotates 180 °, the first seal ring 3 simultaneously on core bar 2 and the second seal ring 6 are along with rotation, the link arm 7 of core bar 2 bottom is also along with core bar 2 rotates, positioning bar 22 on core bar 2 rotates and offsets with the positioning boss 81 of the valve opening state side of opposite side on locating piece 8, the top entity part of core bar 2 was positioned at the lower right of water channel 13, and current can pass through water channel 13 along the inclined-plane 2a on core bar 2 top.
When Anti-leakage valve is in opening state, the reduction torsion spring 4 that core bar 2 is nested with is in twisting states and produces restoring force, the attachment post 14 being connected to valve body 1 bottom produces pulling force with the connecting rod 5 of core bar 2 bottom, mutually balance and make core bar 2 be in equilibrium of forces state between the restoring force that this pulling force and reduction torsion spring 4 produce, thus making Anti-leakage valve be held open state.
When Seepage appears in Anti-leakage valve, the water spilt can flow into the collecting annulus 91 below valve body 1, and water can be connected bar 5 absorbs, and connecting rod 5 loses intensity after absorbing water, and cannot balance restoring force that reduction torsion spring 4 produces and be pulled off; After losing the pulling force of connecting rod 5, core bar 2 rotates in the restoring force effect that reduction torsion spring 4 produces and cut out water channel 13, thus has cut off the water route from water intake 11 to water outlet 12, and closes Anti-leakage valve, thus plays the effect of leakage proof.
After the hidden danger of leaking is eliminated, get off the connecting rod 5 ruptured, and core bar 2 is turned to Anti-leakage valve enable possition, and be connected with attachment post 14 new connecting rod 5 one end, the other end is connected with the link arm 7 of core bar 2 bottom; Anti-leakage valve just can subnormally again employ.
Most preferred embodiment of the present invention is illustrated, and the various change made by those of ordinary skill in the art or remodeling all can not depart from the scope of the present invention.
