Description
Technical field
The utility model relates to a kind of triangle vavle, relates in particular to a kind of leakage-proof triangle vavle.
Background technique
Generally between closet flushing device and pipeline, can be provided with triangle vavle, triangle vavle can opening and closing of fault, control flowing of water source, because present closet flushing device is all placed with sterilized water, and the not anti-sealing adverse current of triangle vavle, cause the water backflow phenomenon of closet flushing device, directly pollute people's domestic water.
In view of this, the inventor, for the above-mentioned defect further investigation of prior art intermediate cam valve, has this case to produce then.
Model utility content
In order to overcome above shortcomings part in prior art, it is simple in structure that the purpose of this utility model is to provide one to have, and prevents the leakage-proof triangle vavle of adverse current.
In order to reach above-mentioned object, the utility model adopts following concrete technological scheme: leakage-proof triangle vavle, it comprises valve body, spool, valve rod, handwheel, valve body is provided with water intake, water outlet, sealing regulate mouthful and and water intake, water outlet is used to logical intake tunnel mutually, on valve body, be provided with the spool for controlling water outlet, spool is arranged on sealing and regulates on mouth, handwheel is arranged on the valve rod of spool, the intake tunnel inner side of described valve body is provided with a stage and an annular spring groove, described stage is provided with a non-return valve core, the lower end of described non-return valve core is provided with the jump ring embedding in jump-ring slot.
The utility model advantage is compared with prior art: the utility model has increased the jump ring of a non-return valve core and fixing non-return valve core on the basis of existing triangle vavle, enable effectively to prevent counter-current of sewage, also can stop the crossfire of hot and cold water, and structural design novelty, feature easy to use.
