The utility model takes following technological scheme to realize above-mentioned purpose:
A kind of wall-hung boiler water-feeding valve, comprise valve body, be arranged at the valve rod of valve inner, the valve gap be spirally connected with valve body upper end and the handwheel affixed with valve rod, the water-inlet cavity be communicated with successively is provided with in described valve body, valve-rod cavity and water chamber, described valve rod bottom is inverted round stage, the inverted round stage top of described valve rod is provided with a groove, a gasket ring is provided with in described groove, described water chamber upper end is the face, round platform chamber with the corresponding cooperation in described inverted round stage inclined-plane, and form black box one with inverted round stage inclined-plane, valve rod lower end surface is for compress cylndrical surface mutually with described gasket ring, and form black box two with gasket ring, in described water chamber, a filter screen is installed.
Described water chamber is made up of the endoporus of endoporus one, endoporus two, endoporus three and endoporus four or four different-diameters, described endoporus one diameter is less than endoporus two, described endoporus three diameter is less than endoporus one and endoporus two, and described endoporus four diameter is less than described endoporus one, endoporus two and endoporus three.Described endoporus four is less than described inverted round stage largest face and is less than described inverted round stage minimal face.
Described filter screen includes net cup and crimping, and described crimping is placed on described endoporus two, and described endoporus two is also provided with back-up ring.
Described valve body is provided with the engaging lug shaping with valve body one-step casting, and described engaging lug is provided with tapped hole.
Described valve rod intermediate section is interlayer, and described interlayer is provided with interlayer groove, described interlayer groove is provided with O type circle.
Described face, round platform chamber and valve-rod cavity lower end surface are Chamfering fillet surface.
The beneficial effects of the utility model be to be provided with one soft seal with together with firmly seal, two seals can improve water-feeding valve sealability.Meanwhile, at water chamber, filter screen is installed, has prevented wall-hung boiler Inner eycle water impurity from entering water-feeding valve inside and cause seepage.The utility model has compared with existing water-feeding valve that good seal performance, structure are simple, easy for installation, the advantage of long service life.
