Description
Technical field
The utility model relates to a kind of water tap, especially relates to a kind of adjustable leakproof faucet valve core.
Background technique
At present, the faucet valve core that adopts ceramic moving plate to cooperate with ceramic stator uses very just general, and this spool has lot of advantages, but still has some shortcomings.After long between in use, can leak because of wearing and tearing cause blow-by between ceramic moving plate and the ceramic stator; The valve core seal ring of being located at ceramic stator below because of wear out and the inwall of spool housing between also can cause poorly sealed leaking.So just water tap to be dismantled often, change ceramic moving plate and ceramic stator and seal ring, thereby increased the maintenance user cost.
Summary of the invention
The purpose of this utility model provides a kind ofly can not change under the spool part prerequisite the adjustable leakproof faucet valve core that effectively prolongs the working life of spool.
The utility model comprises valve core shell, ceramic moving plate, ceramic stator, valve core seal ring and valve rod, ceramic moving plate, ceramic stator and valve core seal ring; Valve rod is located in the valve core shell, the valve core shell upper end is exposed in the valve rod upper end, the gear shaping correspondence of valve rod lower end is embedded in the teeth groove of ceramic moving plate, the pottery moving plate is pressed and is touched on the ceramic stator upper-end surface, its characteristics are, valve rod is provided with threaded central through bore, be provided with adjusting screw rod and locking nut in the valve rod central through bore, adjusting screw rod and valve rod central through bore are spirally connected, the valve rod upper end is exposed in the adjusting screw rod upper end, locking nut and adjusting screw rod are spirally connected and are locked at the valve rod upper-end surface, and the adjusting screw rod lower end is exposed the lower end mouth of valve rod central through bore and pressed and touch on ceramic moving plate upper-end surface.
The medial axis of described adjusting screw rod overlaps with the medial axis of ceramic moving plate, ceramic stator, valve core seal ring, valve rod and valve core shell.
Described adjusting screw rod can be split-type structural, the adjusting screw rod of split-type structural preferably is made of depression bar and screw rod, the depression bar lower end is exposed the lower end mouth of valve rod central through bore and is pressed and touch on ceramic moving plate upper-end surface, the depression bar upper end touches with the screw rod lower end, and the screw rod upper end is exposed the valve rod upper-end surface and is spirally connected with locking nut.Described depression bar lower end is preferably ball arcuation termination, and the central point that can aim at ceramic moving plate when touching on ceramic moving plate is better pressed in ball arcuation termination, avoids producing eccentric the slip.Described depression bar periphery preferably is provided with the sealing lining, and the sealing lining is mainly used in radial seal better between depression bar and the valve rod central through bore.
The beneficial effects of the utility model: during use, the utility model is installed in the valve body of water tap, the internal thread of valve core shell outside thread and valve body is spirally connected, and the internal thread of handgrip and valve rod upper external screw thread be spirally connected get final product.Between ceramic moving plate and ceramic stator,, wearing and tearing leak because of causing blow-by; The valve core seal ring of being located at ceramic stator below because of wear out and the inwall of spool housing between when causing poorly sealed leaking, the handgrip of only need outwarding winding, unclamp locking nut, rotate adjusting screw rod, just can make the adjusting screw rod depression bar that bears down on one downwards, depression bar can make the downward roof pressure of ceramic moving plate still keep tight friction fit between ceramic moving plate and the ceramic stator, thereby has overcome the micro-gap that produces because of wearing and tearing between ceramic moving plate and the ceramic stator.Simultaneously, ceramic moving plate is also oppressed valve core seal ring through ceramic stator when pressing down, and valve core seal ring meeting radial dilatation so also can be eliminated valve core seal ring because of poorly sealed problem between the inwall of aging and spool housing.This shows,, just can effectively solve seepy question by the rotation of adjusting screw rod.And need not change the spool part, it is very simple to regulate operation, greatly reduces user cost, has saved water resources.
Description of drawings
Fig. 1 is the utility model embodiment's a STRUCTURE DECOMPOSITION schematic representation.
Embodiment
Referring to Fig. 1, the utility model is provided with valve core shell 1, ceramic moving plate 2, ceramic stator 3, valve core seal ring 4, valve rod 5, ceramic moving plate 2, ceramic stator 3, valve core seal ring 4, adjusting screw rod (being made of depression bar 6 and screw rod 7) and locking nut 8.Above-mentioned each part is same medial axis.Valve rod 5 is located in the valve core shell 1, and valve core shell 1 upper end is exposed in valve rod 5 upper ends, and 2 symmetrical gear shapings 51 of valve rod 5 lower ends are corresponding respectively to be embedded in 2 symmetrical teeth groove 21 of ceramic moving plate 2.Valve core shell 1 is provided with outside thread 11, and the central through bore of valve core shell 1 is 12, and the shell wall of valve core shell 1 is provided with the inlet 13 of symmetry.
Valve rod 5 upper ends are provided with the central through bore 54 of outside thread 52 and threaded 53, depression bar 6 and screw rod 7 are located in the central through bore 54 of valve rod 5, depression bar 6 lower ends are exposed the lower end mouth of central through bore 54 and are pressed and touch in ceramic moving plate 2 upper-end surfaces, depression bar 6 upper ends and screw rod 7 lower ends touch, valve rod 5 upper-end surfaces are exposed in screw rod 7 upper ends, central through bore 54 screw-thread fit of screw rod 7 and valve rod 5, locking nut 8 cooperate with screw rod 7 and are locked at valve rod 5 upper-end surfaces.
Depression bar 6 lower ends are ball arcuation termination, and the central point that can aim at ceramic moving plate 2 when touching on ceramic moving plate 2 is better pressed in ball arcuation termination, avoid ceramic moving plate 2 to produce eccentric the slip.Depression bar 6 peripheries are provided with sealing lining 61, but radial seal better between the central through bore 54 of sealing lining 61 depression bars 6 and valve rod 5.
During use, when blocking the water port 31 of 2 symmetries of ceramic stator 3 when ceramic moving plate 2 rotates, spool is in closed condition, and water tap is closed; When ceramic moving plate 2 rotated the water port 31 of 2 symmetries of getting out of the way ceramic stator 3 again, spool was in opening state, the water tap conducting.When producing water leakage phenomenon, only need the outward winding handgrip of water tap, unclamp locking nut 8, rotate adjusting screw rod 7, just can make screw rod 7 depression bar 6 that bears down on one downwards, depression bar 6 can make ceramic moving plate 2 downward roof pressures between ceramic moving plate 2 and the ceramic stator 3 still to keep tight friction fit, thereby has overcome between ceramic moving plate 2 and the ceramic stator 3 seepy question that the micro-gap because of the generation of wearing and tearing brings.Simultaneously, ceramic moving plate 2 is also oppressed valve core seal ring 4 through ceramic stator 3 when pressing down, and valve core seal ring 4 meeting radial dilatation so also can be eliminated valve core seal ring 4 because of the poorly sealed seepy question that brings between the inwall of aging and valve core shell 1.By the rotation of adjusting screw rod, just can effectively solve seepy question.And need not change the spool part, it is very simple to regulate operation, greatly reduces user cost, has saved water resources.
