Description
Technical field
The present invention relates to a kind of structure for water tap.
Background technique
The advantages such as plastics are durable because having, waterproof, light weight, low cost of manufacture are used widely in all trades and professions, and working of plastics also replaces copper fitting gradually in structure for water tap.Traditional water tap, at valve rod and spool main body inner chamber limit structure restriction handwheel angle of swing is set, on the one hand, it is stressed larger at handwheel joint extension to cross when twisting valve rod, if its insufficient strength, often twisted off easily, simultaneously, when handwheel is collided in transportation or using process, also very easily cause extension to fracture, if strengthen this extension intensity and the overstriking valve rod, then can increase greatly the manufacturing cost and use cost of whole structure for water tap, and also be unfavorable for the standardization of structure for water tap, therefore valve rod still adopts copper fitting at present.
Summary of the invention
In order to address the above problem, but the invention provides a kind of Effective Raise valve rod intensity, prolong its working life structure for water tap.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of structure for water tap, comprise handwheel, spool main body, valve rod and mangetic core assembly, after packing into from spool main body lower end, described valve rod forms extension by stretching out on the spool main body, the valve core assembly places the holding cavity of spool main body lower end and is driven by valve rod, the top of described spool main body is provided with the screens ear, that handwheel is provided with is suitable with the screens ear, be used for 2 chucking lugs of restriction handwheel angle of swing, and 2 chucking lugs are positioned at screens ear both sides; Also comprise a long spiro nail, long spiro nail is from wearing the bottom to valve rod after the top end of handwheel passes.
As improvement of the technical scheme, described extension is the non-centrosymmetry structure, and handwheel is provided with the jack suitable with the non-centrosymmetry structure.
As further improvement in the technical proposal, described non-centrosymmetry structure is the small semicircle cylinder.
Further, described mangetic core assembly comprises and is connected to definite ceramic chip on the holding cavity inwall, that be provided with the water port, and place the definite ceramic chip top, be provided with into the dynamic porcelain piece of water breach the card base clamping of dynamic porcelain piece and described valve rod lower end.
Further, described mangetic core assembly is locked in the holding cavity with sealed colloid, and sealed colloid is embedded with tensioning ring.
Further, described handwheel top is equipped with trim, and handwheel is positioned at top, long spiro nail position and is provided with groove, and trim after being connected in the groove covers long spiro nail.
Further, described valve rod is socketed with the first seal ring between holding cavity top and extension.
Further, the described spool main body outside is provided with for the outside thread that connects the water inlet and outlet joint, is positioned at the outside thread top position on the spool main body and is socketed with the second seal ring.
The invention has the beneficial effects as follows: 2 chucking lugs and the screens ear on the spool main body on this product handwheel interact, the angle of swing of restriction handwheel, the retaining structure that replaces traditional valve rod and spool main body inner chamber, reduced on the one hand the loss of valve rod, reinforced the intensity of valve rod, be difficult for when it is collided being fractureed, crossed on the other hand when twisting, effect between valve rod and the spool main body becomes the effect between chucking lug and the screens ear, makes valve rod be not easy to be twisted off; Simultaneously long spiro nail is from wearing the bottom to valve rod after the top end of handwheel passes, and the intensity of having reinforced valve rod makes its not frangibility, the simple and reasonable compactness of the present invention, easy for installation, cost is low.
