Description
Technical field
The utility model belongs to spool accessory technical field, is related to a kind of spool, in particular to a kind of wear-resisting property is good
Spool.
Background technique
Tap is that the popular appellation of water valve for controlling the size switch of water flow has water-saving effect.Tap is more
New replacement speed is very fast, develops to plating knob from old-fashioned casting iron craft, and develop to the stainless steel list temperature single control fire hose
Head, stainless steel double temperature double control faucet, the semi-automatic faucet in kitchen, wherein spool is most important a part in tap, spool
Quality directly affects the quality of tap.
The spool of existing traditional structure, since the valve rod in spool is in contact in rotation with spool housing, long-term
In use, be easy to causeing the abrasion of plunger and shell, the leakproofness of valve core inside is reduced, spool is caused water leakage situation occur,
The service life of spool is influenced, while causing the waste of water resource.
Summary of the invention
The purpose of this utility model is to provide a kind of valve that wearability is good for the above-mentioned problems in the prior art
Core.
The purpose of this utility model can be realized by the following technical scheme: a kind of spool that wear-resisting property is good, including valve
Core shell body is equipped with valve rod in the spool housing, and the lower end of valve rod is connected with the ceramic membrane assembly matched with valve rod,
The end of the spool housing is provided with bottom cover, which is characterized in that is provided with wearability between the valve rod and spool housing
Wear-resisting portion that is good and being matched with valve rod, and wear-resisting portion is sheathed on valve rod, the lower end in the wear-resisting portion is provided with radial prolong
The extension stretched is provided with sealing ring between the extension and shell, the seal ring set is set in wear-resisting portion, and close
The inner sidewall of seal ring is in contact with the lateral wall of extension.
In a kind of good spool of above-mentioned wear-resisting property, the lower end surface of the sealing ring and the lower end surface phase of extension
Concordantly.
In a kind of good spool of above-mentioned wear-resisting property, be provided on the lateral wall of the extension several with
Distribution and the fixed column for being used for fixing seal ring, and fixed column is integrated with extension and is arranged.
In a kind of good spool of above-mentioned wear-resisting property, sealing ring is provided between the wear-resisting portion and shaft.
Compared with prior art, the good spool of this wear-resisting property is provided with wear-resisting portion between valve rod and spool housing, resistance to
The lower end in mill portion is provided with extension, and sealing ring is provided between extension and shell.The setting in wear-resisting portion reduce shaft with
The abrasion of spool housing promotes the wearability of spool, while the setting of sealing ring reinforces the leakproofness in spool, increases valve
The service life of core.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view in the good spool of this wear-resisting property.
In figure, 1, spool housing；2, valve rod；3, ceramic membrane assembly；4, bottom cover；5, wear-resisting portion；6, extension；7, it seals
Ring；8, fixed column；9, sealing ring.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, the good spool of this wear-resisting property includes spool housing 1, valve rod 2, valve rod are equipped in spool housing 1
2 lower end is connected with the ceramic membrane assembly 3 matched with valve rod 2, and the end of spool housing 1 is provided with bottom cover 4, valve rod 2 and valve
The wear-resisting portion 5 that wearability is good and matches with valve rod 2 is provided between core shell body 1, wear-resisting portion 5 is sheathed on valve rod 2, wear-resisting portion
5 lower end is provided with the extension 6 radially extended, and sealing ring 7 is provided between extension 6 and shell, and sealing ring 7 is sheathed on resistance to
In mill portion 5, the inner sidewall of sealing ring 7 is in contact with the lateral wall of extension 6.
As preferred structure, the lower end surface of sealing ring 7 and the lower end surface flush of extension 6.
It further describes in detail, in order to make the better tightness of valve core inside, several is provided on the lateral wall of extension 6
With distribution and for the fixed column 8 of fixing seal ring 7, and fixed column 8 is integrated with extension 6 and is arranged.Wear-resisting portion 5 and axis
Sealing ring 9 is provided between bar.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
Although spool housing 1, valve rod 2, ceramic membrane assembly 3, bottom cover 4, wear-resisting portion 5, extension is used more herein
6, the terms such as sealing ring 7, fixed column 8, sealing ring 9, but it does not exclude the possibility of using other terms.Only using these terms
Merely to being more convenient to describe and explain the essence of the utility model；Being construed as any additional limitation is all
It is contrary to the spirit of the present invention.
