TECHNICAL FIELD

[0001] The utility model relates to ceramic valve core technical field, concretely is a kind of ceramic valve core of wear resistance. BACKGROUND

[0002] Ceramic valve core is mainly composed of valve core shell, lever, dynamic valve sheet, static valve sheet, pressing sheet and sealing pad etc., static valve sheet is fixed in valve core shell, it has two opposite water inlet through holes on it, dynamic valve sheet is adhered to static valve sheet, and it is opened with the water outlet through hole corresponding to water inlet through hole, lever is inserted in valve core shell, and lower end is clamped on dynamic valve sheet by lever fork, and lever has through hole consistent with the direction of central axis, when lever is moved, lever drives dynamic valve sheet to rotate, so that the water outlet through hole on dynamic valve sheet corresponds to the water inlet through hole on static valve sheet, realizes the conduction and cut-off of water flow, to control the outflow of water.

[0003] Because ceramic valve core controls the size and on-off of water flow by rotating, lever is used as the driving component of valve core rotation, and it is easy to cause lever to be excessively moved in the process of moving, excessive force friction between lever and the component supporting it, with the lapse of time, the friction can cause lever to be worn, and worn lever can make valve core not flexible, even appear jamming phenomenon, seriously affect the normal use of ceramic valve core, reduce the service life of product and user experience, for this, we propose a kind of ceramic valve core of wear resistance.

[0025] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Please refer to Figures 1-2 The utility model provides a kind of technical scheme: a wear-resistant ceramic valve core, including valve body 1, valve body 1 one end is equipped with valve pad 2, the other end of valve body 1 is equipped with lever 3, the surface of lever 3 is equipped with protective structure 4, protective structure 4 includes rectangular ring 401, rectangular ring 401 is sleeved on the surface of lever 3, the both sides of rectangular ring 401 are slidably equipped with bolt 402, the both sides of lever 3 are equipped with round groove 403, the size of bolt 402 is compatible with the size of round groove 403, the both sides of rectangular ring 401 are fixedly connected with internally threaded tube 404, the inner wall of internally threaded tube 404 is threadedly connected with threaded rod 405, by being equipped with protective structure 4, it reaches to avoid lever 3 to be excessively stirred, to avoid that lever 3 is worn, to guarantee the service life of lever 3 further.

[0027] Refer to Figure 3 And Figure 4 With Figure 5As shown in this embodiment: a spring 406 is fitted onto the arc surface of the pin 402. The two ends of the spring 406 are fixedly connected to the pin 402 and the rectangular ring 401, respectively. The spring 406 enhances the stability of the pin 402 inserted into the circular groove 403. A ball 407, made of rubber, is fixedly connected to the end of the threaded rod 405 away from the internal threaded tube 404. The ball 407 prevents the threaded rod from contacting the valve body 1, thus avoiding wear on the valve body 1. A turntable 408 is fixedly connected to the surface of the threaded rod 405. The vertical cross-section of the turntable 408 is cross-shaped. Rotation of the turntable 408 causes the threaded rod 405 to rotate, facilitating the rotation of the threaded rod 405. Extension plates 409 are fixedly connected to both sides of the lever 3. A rectangular ring 401 is attached to the surface of the extension plate 409. When the rectangular ring 401 is attached to the surface of the extension plate 409, the extension plate 409 restricts the position of the rectangular ring 401, thereby allowing for quick positioning of the rectangular ring 401 at the required installation location. A slanted groove 410 is provided on the inner wall of one end of the rectangular ring 401. Because the inner wall of the rectangular ring 401 has a slanted groove 410, it is convenient to fit the rectangular ring 401 onto the surface of the lever 3.

[0028] Working Principle: When installing the ceramic valve core, first, the rectangular ring 401 is placed on the surface of the lever 3. Because the inner wall of the rectangular ring 401 has an inclined groove 410, it is easy to place the rectangular ring 401 on the surface of the lever 3. When the rectangular ring 401 is in contact with the surface of the extension plate 409, the pin 402, with the help of the spring 406, will be firmly inserted into the circular groove 403. The pin 402 restricts the position of the rectangular ring 401, thus fixing the rectangular ring 401 to the surface of the lever 3. The spring 406 enhances the stability of the pin 402 inserted into the circular groove 403. The extension plate 409 restricts the position of the rectangular ring 401, allowing for quick positioning of the rectangular ring 401. Then, the lever 3 is moved to open the ceramic valve core. At this time, the turntable 40... 8. The rotation of the turntable 408 will drive the threaded rod 405 to rotate. The rotation of the threaded rod 405 will move within the internal threaded tube 404 by means of the thread. The threaded rod 405 will gradually disengage from the internal threaded tube 404. The movement of the threaded rod 405 will drive the ball 407 to move. When the ball 407 is in contact with the surface of the valve body 1, the threaded rod 405 will be adjusted to a suitable length. Then, the lever 3 will be turned to put the ceramic valve core in the closed state. The above operation is repeated to adjust the threaded rod 405 to a suitable length. At this time, the adjustment of the protective structure 4 is completed. When using the ceramic valve core, the balls 407 on both sides of the rectangular ring 401 will limit the turning angle of the lever 3, thereby avoiding excessive turning of the lever 3 and thus avoiding wear on the lever 3. The balls 407 achieve the function of preventing the screw from contacting the valve body 1, which would cause wear on the valve body 1.
