Technical field
The utility model relates to a kind of ceramic valve core, particularly seals adjustable ceramic spool.
Background technique
Faucet valve core in the market is ceramic valve core normally, because the ceramic valve core chemical stability is good, long working life, obtains to use widely.
Current ceramic valve core generally all assembles; Spool feel, sealing, high pressure resistant property are determined by the precision of the numerous component of spool; Its integrating error are big after all component assemblings, and this has also just proposed very high request to the dimensional accuracy of each part, make that manufacturing difficulty is big.Can to occur assembling unavoidably after through assembling not good for each parts in addition, or can cause that ceramic moving plate is excessive with the friction of ceramic still, makes both can't slide relative, or can influence the sealability of spool integral body.And, after long-term the use, there have been certain wearing and tearing between each parts, will inevitably influence each sealing surface sealing of ceramic valve core, make spool the problem that seeps water, leaks occur, reduced the working life of spool.Under present technical specifications, above-mentioned problem is difficult to avoid, and therefore, needs a kind of ceramic valve core that can improve the problems referred to above on the market.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of rational in infrastructure, reliable in quality, the adjustable ceramic spool of sealing.
The technological scheme that the utility model adopted is:
The adjustable ceramic spool of a kind of sealing; Comprise housing and with the base of its clamping, enclosure interior is provided with driving lever from top to bottom successively, clamp and be fixed on the ceramic moving plate on the dial and clamp the ceramic still that is fixed on the base, the driving lever middle part is located in the support; And through being fixed on fulcrum and the support pivot joint on the support; The support lower end is connected with dial, and driving lever is terminal to be connected and to drive dial with dial and slide along support in the direction of stirring of driving lever, is provided with pressure ring between said housing and the support; The pressure ring lower end is connected with support, and housing is stretched out in the upper end; Said case top is provided with the adjustment sleeve that is used to press pressure ring; Adjustment sleeve is stretched out in said driving lever upper end.
Further, said support lower end is provided with the annular brace portion that is used to support pressure ring, and the pressure ring lower end is positioned on the supporting portion.
Further, said adjustment sleeve is threaded with housing, and adjustment sleeve is provided with the compressed part that is used to press pressure ring.
Further, said compressed part is the ring-shaped platform with the adjustment sleeve one.
Further, said dial central authorities are provided with corresponding with the driving lever terminal end shape and hold the terminal through hole of driving lever.
Further, be arranged with to the boss that extends below on the said frame bottom circumference, dial is provided with the breach that cooperates with boss and can slide along boss.
Further, be provided with inner seal ring between said ceramic still and the base, the base bottom is provided with exterior seal ring.
The beneficial effect of the utility model is: the utility model compresses pressure ring through adjustment sleeve, can increase the applying degree between ceramic still and the ceramic moving plate, enhance seal performance; Through loosening pressure ring with adjustment sleeve, can reduce the friction between ceramic still and the ceramic moving plate, make both more be prone to relative movement.The design of the utility model has effectively improved owing in production and assembly process the problem that the caused sealability of defective is not good, spool is difficult to opening and closing that exists between each component of spool; Reduced processing request to each part; Reduce cost of production, guaranteed the conformity of spool parameter, improved the reliability of spool; Prolong the working life of spool, had stronger use value.

Embodiment
Like Fig. 1-shown in Figure 3, the adjustable ceramic spool of a kind of sealing, the base 2 that comprises housing 1 and connect and fix with it.Housing 1 hollow inner is provided with driving lever 3 from top to bottom successively, clamps and be fixed on the ceramic moving plate 5 on the dial 4 and clamp the ceramic still 6 that is fixed on the base 2.
The top of dial 4 is connected with support 7, support 7 and housing 1 radial location, and driving lever 3 passes support 7, and the middle part is located in the support 7, and support 7 center fixed have a fulcrum 8, and driving lever 3 articulates through fulcrum 8 and support 7, can rotate around fulcrum 8.
Be arranged with to the boss that extends below 72 on the circumference of support 7 bottoms, dial 4 is provided with the breach 42 that cooperates with boss 72, makes boss 72 to slide along breach 42.
In the present embodiment, have hot and cold water intake and a water outlet on the base 2, have respectively on the ceramic still 6 and hot and cold water intake and the corresponding flow channel of water outlet.Be provided with inner seal ring 12 between pottery still 6 and the base 2, be used to guarantee the water tightness of 2 of ceramic still 6 and bases.Base 2 bottom surfaces also are provided with exterior seal ring 13, are used to guarantee the sealability between whole ceramic valve core and the outside valve body.
In the present embodiment, be provided with pressure ring 9 between housing 1 and the support 7, pressure ring 9 is just filled up the space between full housing 1 and the support 7.Support 7 lower ends form an annular brace portion 71, are used to support pressure ring 9, and pressure ring 9 lower ends are positioned on the supporting portion 71, and housing 1 is stretched out in the upper end.Housing 1 top is through the adjustment sleeve 10 that has been threaded, and adjustment sleeve 10 is stretched out in driving lever 3 upper ends.Adjustment sleeve 10 is provided with the compressed part 11 that is used to press pressure ring 9, and compressed part 11 is the ring-shaped platforms with adjustment sleeve 10 one.After tightening adjustment sleeve 10, compressed part 11 acts on the pressure ring 9, and the transmission through power acts on ceramic moving plate 5 and the ceramic still 6 at last, has increased sealability between the two, has also increased the sealability of ceramic still 6 and base 2 simultaneously.After loosening adjustment sleeve 10, the pressure between pressure ring 9 and the support 7 diminishes, and 6 of ceramic moving plate 5 and ceramic stills more are prone to relative movement.
Like Fig. 4, shown in Figure 5, when the user stirred driving lever 3, driving lever 3 rotated on fulcrum 8, drove dial 4 and slided with ceramic moving plate 5.Hot and cold water intake on the pottery still 6 is communicated with water outlet, and water outlet goes out warm water.The angle Y that driving lever 3 is stirred is big more, and water outlet is many more.
As shown in Figure 6, go out warm water after, can rotate driving lever 3, drive ceramic moving plate 5 and rotate on ceramic still 6 surfaces, adjust the flow of inlet water of hot water or cold water's water intake respectively, reach the purpose that adjusts coolant-temperature gage.The maximum angle of swing of driving lever 3 is X, and when rotating to two ends respectively, water outlet only goes out hot water or only goes out cold water.
The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection domain.
