[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-3 In this embodiment, a press-type quick-opening ceramic valve core controls the opening and closing of the ceramic valve core by pressing, thereby solving the problem that the planar rotation mechanism of the quick-opening ceramic valve core needs to be frequently switched, and is prone to wear or damage caused by particle entry after long-term use.
[0026] Specifically, it includes a valve body 1, a sleeve 2, a valve stem 3, a sealing member 4 and an opening and closing cylinder 5;
[0027] The sleeve 2 is penetrated and arranged on the inner top wall of the valve body 1, the valve stem 3 is slidably connected to the inside of the sleeve 2, the seal 4 is threadedly connected to the outside of the sleeve 2, and a through hole is opened on the top of the seal 4 for the valve stem 3 to move up and down; the opening and closing cylinder 5 is arranged inside the valve body 1, and the bottom end of the valve stem 3 is equipped with a connecting bolt 8 with one end penetrating and extending into the inside of the valve body 1, and the connecting bolt 8 is transmission-connected with the opening and closing cylinder 5 to drive the opening and closing cylinder 5 to move up and down; a first drain port 6 is opened on the outer peripheral wall of the valve body 1, and a second drain port 7 is opened on the outside of the opening and closing cylinder 5 corresponding to the first drain port 6, so that the second drain port 7 is connected with the first drain port 6 when the opening and closing cylinder 5 moves downward.
[0028] During actual use, the valve stem 3 is pressed to drive the connecting bolt 8 connected to it to move downward, thereby pushing the opening and closing tube 5 to move downward, that is, when the second drain port 7 inside the opening and closing tube 5 is connected to the first drain port 6 on the sleeve 2, the water input through the bottom of the valve body 1 can be discharged through the first drain port 6 and the second drain port 7, so that the ceramic valve core can be quickly opened.
[0029] Furthermore, in order to ensure that the valve stem 3 can drive the opening and closing tube 5 to move upward when not subjected to force, a compression spring 9 is installed between the inner bottom wall of the sleeve 2 and the valve stem 3 in this embodiment, and the compression spring 9 is sleeved on the outside of the valve stem 3.
[0030] During actual use, when the valve stem 3 is pressed down, the valve stem 3 will compress the compression spring 9, and the compression spring 9 will have a certain elastic potential energy, that is, after the valve stem 3 is released, the compression spring 9 can automatically rebound, thereby pushing the valve stem 3 and the opening and closing tube 5 to move upward, so that the second drain outlet 7 is staggered with the first drain outlet 6, thereby closing the ceramic valve core.
[0031] It should be noted that the diameter of the connecting bolt 8 is smaller than the diameter of the valve stem 3; corresponding to the connecting bolt 8, a through hole for the connecting bolt 8 to pass through is opened on the inner bottom wall of the sleeve 2, so that the connecting bolt 8 can drive the opening and closing tube 5 to move up and down.
[0032] In addition, in order to ensure the sealing effect between the opening and closing cylinder 5 and the valve body 1, the outer diameter of the opening and closing cylinder 5 in this embodiment is adapted to the outer diameter of the valve body 1, and the first drain outlet 6 and the second drain outlet 7 are located on the same vertical line, so that when the opening and closing cylinder 5 moves downward, the second drain outlet 7 can be effectively connected with the first drain outlet 6.
[0033] Furthermore, in order to improve the stability of the valve stem 3 when it moves downward, slide grooves 10 are vertically opened on the left and right sides of the inner wall of the sleeve 2. Corresponding to the two slide grooves 10, sliders 11 are installed on the left and right sides of the valve stem 3 so that the sliders 11 can move up and down along the extension direction of the slide grooves 10.
[0034] In actual use, when the valve stem 3 moves up and down, the two sliders 11 on its outer side move up and down along the extension direction of the two slide grooves 10, so as to ensure the stability of the valve stem 3 when moving.
[0035] In addition, in order to fix the position of the valve stem 3, a connecting groove 12 is horizontally opened at the bottom of the two slide grooves 10, and the extension directions of the two connecting grooves 12 are opposite, and the connecting groove 12 and the slide groove 10 are combined to form an L-shaped guide groove.
[0036] In actual use, after the first drain outlet 6 is connected with the second drain outlet 7, the two sliders 11 are extended to the inside of the two connecting grooves 12 by rotating the valve stem 3, so that the two sliders 11 cannot move up and down independently, and when the ceramic valve core needs to be closed, the two sliders 11 on the outside of the valve stem 3 are moved from the inside of the two connecting grooves 12 to the inside of the two slide grooves 10 by rotating the valve stem 3. At this time, when the compression spring 9 rebounds, it can push the valve stem 3 and the opening and closing tube 5 to move upward, so that the first drain outlet 6 and the second drain outlet 7 are misaligned.
[0037] In actual setting, the width of the second drain port 7 is greater than the width of the first drain port 6 to avoid a reduction in water flow during the rotation process.
[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
