The water nozzle comprises a valve body, a valve cover arranged at the upper end of the valve body, a static tile, a movable tile and the valve rod which are arranged in the valve body from the bottom up, and a two-stage stepped fixed ring with the two ends open, wherein a boss is arranged in the valve body; the outside diameter of a first step ring is greater than that of a second step ring; at least one notch is formed on the outer edge of the first step ring; the fixed ring is sleeved outside the valve rod to fix the valve rod in the valve body; the boss is clamped into the notches; and the second step ring is arranged in a slot formed between the valve rod and the valve body. The fixed ring is divided into a three-stage step shape, and in a rotation process of the valve rod, the fixed ring is in surface connection with the valve rod and the valve body, so that stressing is uniform, deformation is low, the valve rod is more stable, and a product yield is increased.
Description
Technical field
The present invention relates to a kind of ceramic valve core water nozzle, be specifically related to the stable water nozzle of a kind of valve rod.
Background technique
Existing ceramic valve core water nozzle, comprises valve body, is arranged at the valve gap of valve body upper end, is arranged at the definite ceramic chip in valve body, dynamic porcelain piece and valve rod from below to up, and is enclosed within the outer fixing three-jaw be fixed on by valve rod in valve body of valve rod.Described fixing three-jaw is the toroidal of both ends open, the outer wall of fixing three-jaw be provided with 3 outwards above extend tactilely to grab, touch the positioning block of grabbing for being stuck in valve interior wall, move to prevent on fixing three-jaw, and also offer 1 along its axially extended bayonet socket at the outer wall of fixing three-jaw, this bayonet socket is corresponding with the boss in valve body, when mounted, bayonet socket aims at the boss in valve body, is pressed in valve body, is fixed tightly in fixing three-jaw in valve body by valve rod.This design, when rotary valve cover, 3 tactile grabbing make appearance be out of shape because there is discontinuity equalization, and then make valve rod steady, the dynamic porcelain piece of valve rod lower end can not be opened completely or closed permeable mouth, the phenomenon occurring that the water yield is little or leak; In addition because the boss in fixing three-jaw and valve body only has an aligned position, also namely only has unique mounting point, when mounted, alignment precision requires high, and not only installation rate is slow, manufacturing efficiency is low, and offsets a little as position, then extruding is produced to valve body, destroy valve body; And valve rod and valve body, connection between valve gap and valve gap built on the sand, during use, valve rod rotates under the drive of valve gap, rocking of valve rod can be caused, increase the stressed of valve rod, cause valve rod to be easy to fracture, the permeable hole on definite ceramic chip cannot be closed with dynamic porcelain piece, cause water nozzle to leak.
Summary of the invention
Technical problem to be solved by this invention is to provide the stable water nozzle of valve rod that a kind of porcelain heart valve is more steady, conforming product rate is high.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
The stable water nozzle of a kind of valve rod, comprise valve body, be arranged at the valve gap of valve body upper end, be arranged at the definite ceramic chip in valve body, dynamic porcelain piece and valve rod from below to up, boss is provided with in described valve body, also comprise the stepped retaining ring of two-stage of both ends open, wherein the external diameter of the first cascade ring is greater than the external diameter of the second cascade ring, at least one recess is offered in the outer rim of the first cascade ring, valve rod is fixed in valve body by described Fixing shrink ring outside valve rod, and described boss snaps in recess, described second cascade ring is then placed in the slot that formed between valve rod and valve body.
Unlike the prior art, present invention eliminates the existing central design fixing valve rod with fixing three-jaw, changing into valve rod, valve body is that the better retaining ring of smoothness that face, face is connected fixes valve rod.
Such scheme is preferred, and described recess is 3, and these 3 recesses are evenly opened in the outer rim of the first cascade ring.The outer rim of the first cascade ring offers 3 recesses, and the boss in valve body only has one, the arbitrary recess in the outer rim of the first cascade ring can be assembled with the boss in valve body, make the rigging position of retaining ring be three, be convenient to install and fix, improve installation efficiency.
In order to the difficulty of the intensity and installation of taking into account retaining ring, described recess is wide is 2mm.
In order to make the boss in valve body easierly can snap in recess on retaining ring, and connect compact, the cross section of the boss in described valve body is semicircle, and its radius is 0.9mm.
In order to make retaining ring more firm, described first cascade ring top is also provided with cascade ring, and on this, the external diameter of cascade ring is less than the external diameter of the first cascade ring; Valve interior wall is provided with 2 positioning blocks, and the first cascade ring is stuck in below positioning block.
Such scheme is preferred, diametrically same at valve interior wall of described positioning block.
In order to make valve rod more firm be fixed in valve body, the internal diameter of described second cascade ring is greater than the internal diameter of the first cascade ring, and the corresponding external diameter at the second cascade ring place of described valve rod and the internal diameter of the second cascade ring match.
Compared with prior art, retaining ring of the present invention is divided into 3 grades of stairsteppings, under first cascade ring is stuck in the positioning block of valve interior wall, can prevent retaining ring from moving up, in the slot that second cascade ring insertion valve rod outer wall and valve interior wall are formed, retaining ring can be prevented move down, make retaining ring can be fixed in valve body by firm for valve rod, and the internal diameter of the second ladder is greater than the internal diameter of the first ladder, to mate the stairstepping of valve rod outer wall, the connection of further reinforcement valve rod and retaining ring, and then also strengthen the connection of valve rod and valve body, in valve rod rotation process, retaining ring and valve rod, valve body is that face, face connects, uniform force, deformation quantity is little, make valve rod more steady, improve the up-to-standard rate of product, the connection of valve rod and valve body, retaining ring and valve rod and valve body is more compact, firm in addition, and during rotation, valve rod is stressed little, extends working life.
