Abstract
The utility model relates to the field of tap valve spools, in particular to a wear-resistant quickly-opened valve spool. The wear-resistant quickly-opened valve spool comprises a valve body, a valve rod sleeved in the valve spool, a ceramic movable chip clamped to the lower end face of the valve rod as well a ceramic fixed chip, a retainer ring and a sealing washer which are sequentially arranged on the lower end face of the ceramic movable chip, wherein a sealing ring is arranged between the lower part of an upper shaft shoulder and the valve body; another sealing ring is arranged between a lower shaft shoulder of the valve rod and the valve body; a gasket is arranged between the lower end face of the valve rod and the ceramic movable chip; and an O-shaped ring is arranged outside the valve body. According to the wear-resistant quickly-opened valve spool disclosed by the utility model, the sealing rings are distributed at the lower part of the upper shaft shoulder of the valve rod and the lower shaft shoulder of the valve rod in the structure of the quickly-opened valve spool, so that the sealing rings are sleeved at different shaft diameters of the valve rod and further the stress point concentration is avoided and the wear of the sealing rings is reduced; the gasket is arranged between the lower end face of the valve rod and the ceramic movable chip, so that the friction between the ceramic movable chip and the valve rod can be reduced and certain filtering and throttling actions are achieved; and according to an integral structure, the service life of the valve spool is ensured and prolonged.
Description
Technical field
The utility model relates to the faucet valve core field, especially relates to a kind of wear-resisting quick-opened valve core.
Background technique
Quick-opened valve core in the existing market includes valve body, valve rod, ceramic moving plate and ceramic stator; Be provided with seal ring between valve rod and the valve body, because of the structure of most of spool all is the same diameter of axle place that seal ring is arranged on the valve rod top, this just makes when seal ring rubs with valve body; Together in the wearing and tearing of same place; Force bearing point is concentrated, and causes wear extent to strengthen, thereby influences the working life of spool.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of quick-opened valve core of wear-resisting, longer service life is provided.
For realizing above-mentioned purpose; The technical solution of the utility model is: a kind of wear-resisting quick-opened valve core; Comprise the valve rod of socket in valve body, the valve body, ceramic stator, collar and the seal washer that is connected in the ceramic moving plate of valve rod lower end surface and is located at ceramic moving plate lower end surface successively; On the said valve rod shaft shoulder by down being provided with seal ring between place and the valve body, be provided with seal ring between shaft shoulder place and the valve body under the said valve rod.
Preferably, be provided with pad between said valve rod lower end surface and the ceramic moving plate.
Preferably, be provided with O type circle outside the said valve body.
Through adopting above-mentioned technological scheme; The beneficial effect of the utility model is: in the structure of quick-opened valve core with seal ring distribute the shaft shoulder on the valve rod by shaft shoulder place under place down and the valve rod, make seal ring be socketed in the different diameters of axle place of valve rod, avoid force bearing point concentrated; The ring wear amount that causes strengthens; Reduce the wearing and tearing of seal ring, be provided with pad between valve rod lower end surface and the ceramic moving plate, can effectively reduce the friction of ceramic moving plate and valve rod; And playing certain filtration throttling action, overall structure guarantees and has prolonged the working life of spool.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, a kind of wear-resisting quick-opened valve core of the utility model comprises valve rod 1, jump ring 2, valve body 3, seal ring 4, O type circle 5, ceramic moving plate 8, ceramic stator 9, collar 10, seal washer 11; Valve rod 1 is socketed in the valve body 3, and with jump ring 2 valve rod 1 is positioned on the valve body 3, and the last shaft shoulder of valve rod 1 is by locating to be equipped with seal ring 4 down; Seal ring 4 is positioned at the inner upper end of valve body 3, makes between the last shaft shoulder and the valve body 3 of valve rod 1 to fit through seal ring 4, and seal ring 6 is socketed in the following shaft shoulder place of valve rod 1; Pottery moving plate 7 is connected to the lower end surface of valve rod 1, is provided with pad 7 between valve rod 1 and the ceramic moving plate 7, can effectively reduce the friction of ceramic moving plate 8 and valve rod 1; And play certain filtration throttling action; Ceramic stator 9 is fixed on the valve body 3, and with collar 10 and seal washer 11 locator qualifications, the lower end surface of the upper-end surface of ceramic stator 9 and ceramic moving plate 8 fits tightly; Be lining in the collar 10 in the seal washer 11, valve body 3 outsides are provided with O type circle 5.Joint place at seal ring 4, seal ring 6 and ceramic stator 9 and ceramic moving plate 8 all is coated with lubricant oil; Thereby reduce spool steering force, the amount of reducing wear, improve sealing, the seal ring 4 and the seal ring 5 of the utility model is distributed on the valve rod 1 leaning on of the shaft shoulder and locates down and 1 time shaft shoulder place of valve rod, is socketed in the different diameters of axle of valve rod 1; Effectively avoid force bearing point to concentrate; The ring wear amount that causes strengthens, thereby reduces the wearing and tearing of seal ring, and overall structure guarantees and prolonged the working life of spool.
Above-described, be merely a preferred embodiment of the utility model, can not limit the scope that this practicality is implemented, every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
