Description
Technical field
The present invention relates to drinking machine and manufacture field, especially refer to a kind of Anti-leakage valve, refer to especially a kind of water route Anti-leakage valve that is applicable to Household water treatment device.
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, also can cause that house decoration is destroyed to be fallen, and causes the pain in the neck of great loss ，Shi manufacturer.How a lot of manufacturers also prevent seepage in research energetically, and have worked out some and prevent the device of seepage, but a large amount of use not 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 is controlled water route and is comprised of two-part: a part is solenoid valve, for controlling main water route; Another part is leakage inspector.Leakage inspector generally comprises water channel and two the induction terminals that are arranged at product bottom, and water channel is for collecting the water of seepage; When overboard phenomenon appears in equipment, two induction terminals in water channel form path, just can pass out water leakage, control the closed electromagnetic valve in main water route, thereby cut off water route, reach waterproof effect.This mode is to use at present generally, sensitive height, as long as there is percolating water, just quick closing valve water-blocking path very, well plays preventing water leakage function; But complex structure, production and assembly difficulty is large, and price is high, generally on mid-to high-end product, uses; This device under moist environment, there will be wrong report phenomenon sometimes.
The method that detects water route variation in water pressure, is on water route, to increase pressure switch, by the magnitude relationship of hydraulic pressure and pressure switch initial value, controls water route.This controlling method sensitivity is very low, only have a large amount of leak or the leaking of long period after, water route hydraulic pressure just can change, and just can make pressure switch close, thereby play waterproof effect.This mode is easy to install, but sensitivity is low, to leaking on a small quantity and the percolating water of joint of water route, is generally difficult to detect.
On main water route, establish buck booster water pump, water route pressure to be controlled to the minimum hydraulic pressure of a use, while having prevented that hydraulic pressure is excessive and produce water route water leakage phenomenon, but bad to water route assembling, and the percolating water of the joint causing can not detect and control, product still has the possibility of leaking.
At the easy leakage area of product, increasing water-collecting bag, is that the water of seepage is collected, and is then directed to sewerage, can protect like this house decoration not to be destroyed, and does not still turn-off in main water route, and water continues leaking.Like this, still can cause the waste of great lot of water resources, meanwhile, such product has narrow limitation while installing, and consider to be installed to the place of sewerage.

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, the second seal ring 6 is 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 and blocked and close by core bar 2, on the positioning bar 22 on core bar 2 and locating piece 8, the positioning boss 81 of valve closed condition side offsets.In the time of need to opening Anti-leakage valve, core bar 2 rotates 180 °, the first seal ring 3 on core bar 2 and the second seal ring 6 are along with rotation simultaneously, the link arm 7 of core bar 2 bottoms is also along with core bar 2 rotates, on positioning bar 22 rotations on core bar 2 and locating piece 8, the positioning boss 81 of the valve opening state side of opposite side offsets, 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 tops.
When Anti-leakage valve is during in opening state, the reduction torsion spring 4 being nested with on core bar 2 produces restoring force in twisting states, be connected in the attachment post 14 of valve body 1 bottom and the connecting rod of core bar 2 bottoms 5 generation pulling force, balance and make core bar 2 in equilibrium of forces state mutually between the restoring force that this pulling force and reduction torsion spring 4 produces, thus make Anti-leakage valve be held open state.
When Seepage appears in Anti-leakage valve, the water spilling can flow into the collecting annulus 91 of valve body 1 below, and water can be connected bar 5 and absorb, and after connecting rod 5 water suctions, loses intensity, the restoring force cannot balance reduction torsion spring 4 producing and being pulled off; Lost after the pulling force of connecting rod 5, the restoring force effect that core bar 2 produces at reduction torsion spring 4 rotates and closed water channel 13, thereby has cut off the water route from water intake 11 to water outlet 12, and closes Anti-leakage valve, thereby plays the effect of leakage proof.
After the hidden danger of leaking is eliminated, the connecting rod 5 that gets off and ruptured, turns to Anti-leakage valve enable possition by core bar 2, and new connecting rod 5 one end are connected with attachment post 14, and the other end is connected with the link arm 7 of core bar 2 bottoms; Anti-leakage valve just can normally have been used again.
Most preferred embodiment of the present invention is illustrated, and the various variations of being made by those of ordinary skills or remodeling can not depart from the scope of the present invention.
