Abstract
The utility model discloses a structure for surfacing a bearing neck and a bearing component of a valve shaft of a water treatment plug valve. The structure comprises a valve body, a valve cover, a plug and the valve shaft. The valve cover is mounted on the valve body, and the valve shaft and the plug are integrally manufactured. The utility model is characterized in that: the structure further comprises a self-lubricating bearing; a stainless steel corrosion resistant material layer is surfaced at the position of the bearing neck on the valve shaft; the self-lubricating bearing is mounted in a center axle hole of the valve cover; the self-lubricating bearing and the stainless steel corrosion resistant material layer form a rotating pair; and a transition or interference fit is formed by the external diameter of the self-lubricating bearing and the center axle hole of the valve cover. As the stainless steel corrosion resistant material layer which is difficult to rust is arranged on the valve shaft, the water treatment plug valve does not cause difficult opening and closing phenomena due to being not operated for a long term. Therefore, the bearing force of the self-lubricating bearing is correspondingly improved; and the structure can be applicable to the plug valve with any specification. The structure has small friction coefficient, meets the requirements on the environmental friendless, and operation torque of the valve is small.
Description
Technical field
The utility model relates to the structure of a kind of water treatment stopcock valve shaft built-up welding axle journal and bearing part, and specifically a kind of mechanical structure of being associated with bearing of valve shaft belongs to the mechanical structure technical field.
Background technique
In existing technology; The water channel of outlet developed country is with the general integrated type spool that adopts in the stopcock; Be that valve shaft and stopper are processed one, and adopt cast iron materials to process more that the bearing that forms revolute pair with valve shaft generally adopts copper-base powder metallurgy bearing (oil-impregnated bearing).Because valve shaft is an ironcasting, under situation about often not opening and closing, be easy to generate rust staining, cause the valve opening and closing difficulty; Simultaneously, copper base oil containing bearing bearing capacity is not high, in large-scale stopcock working life extremely short, and the lubricant oil in the bearing hole has certain contaminativity to water quality.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, thereby the structure of a kind of water treatment stopcock valve shaft built-up welding axle journal and bearing part is provided, and it can not produce the valve opening and closing difficulty of getting rusty and causing because of valve shaft, and bearing capacity is high, long service life.
According to the technological scheme that the utility model provides, the structure of a kind of water treatment stopcock valve shaft built-up welding axle journal and bearing part comprises valve body, valve gap, stopper, valve shaft; On the said valve body valve gap is housed; Said valve shaft and stopper are processed one, and characteristic is: also comprise self oiling bearing, axle journal position built-up welding stainless steel corrosion resistant material layer on the said valve shaft; In the central shaft hole of said valve gap self oiling bearing is housed, self oiling bearing and stainless steel corrosion resistant material layer form revolute pair; The central shaft hole transition or the interference fit of self oiling bearing external diameter and valve gap.
As further improvement of the present invention; Said self oiling bearing is to be matrix with the steel plate; The mesosphere is the Oilite bronze material of sintering, and inner hole surface is rolling to be main lead-free mixture with the polytetrafluoroethylene, and has replaced the copper base oil containing bearing in the prior art with self oiling bearing.
Compared with present technology the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable; Because valve shaft is provided with the anti-corrosion overlay cladding of the stainless steel that is difficult for getting rusty, so even the long-term inoperation of valve can not cause the phenomenon that opens and closes difficulty yet; Self oiling bearing adopts steel plate to make matrix, and the mesosphere is a bronze material, and density of material is higher than the copper base oil containing bearing in the prior art, and bearing capacity obtains corresponding raising, goes on the stopcock of any specification; The self oiling bearing bore area has adopted lead-free polytetrafluoroethyl-ne lean mixture, and friction factor is little, and the valve operation moment of torsion is little, and compliance with environmental protection requirements.
Description of drawings
Fig. 1 is the utility model embodiment schematic representation.
Fig. 2 is the I place enlarged view among Fig. 1.
Embodiment
Following the utility model will combine accompanying drawing to further describe:
Like Fig. 1, shown in Figure 2: present embodiment comprises valve body 1, valve gap 2, stopper 3, valve shaft 3-1, axle journal 3-2 and self oiling bearing 4.
Said valve shaft 3-1 and stopper 3 are processed one, and the axle journal 3-2 built-up welding stainless steel corrosion resistant material layer on the valve shaft 3-1 is equipped with self oiling bearing 4 in the central shaft hole of valve gap 2, and self oiling bearing 4 forms revolute pair with axle journal 3-2; Said self oiling bearing 4 is to be matrix with the steel plate, and the mesosphere is the Oilite bronze material of sintering, and internal surface (brearing bore face) is rolling to be main lead-free mixture layer with the polytetrafluoroethylene, and has replaced the copper base oil containing bearing in the prior art with self oiling bearing.The central shaft hole transition or the interference fit of said self oiling bearing 4 external diameters and valve gap 2.
When valve shaft 3-1 rotated, the axle journal 3-2 that drives on the valve shaft 3-1 rotated in the bearing hole of self oiling bearing 4, because valve shaft 3-1 is integrative-structures with stopper 3, thereby made stopper 3 do corresponding the rotation, the unlatching of realization valve or close.
Evidence through embodiment: the utility model can obviously reduce the operational torque of valve, and bearing capacity is big, long service life, and complete compliance with environmental protection requirements.
