Description

Technical Field

[0001] The utility model relates to the technical field of valve core shells, in particular to an alumina ceramic valve core shell. Background Technique

[0002] Alumina ceramics have good conductivity, mechanical strength and high temperature resistance, so they are particularly suitable for making valve cores; and the valve cores made of alumina ceramics require corresponding shells to be adapted;

[0003] In the related art, the shells for installing alumina ceramic valve cores mostly have such a structure: the shell includes a shell body, an upper cover and a lower cover are respectively adapted to the upper and lower ends of the shell body, a cavity is opened inside the shell body, and a valve core is placed inside the cavity; at the same time, a handle and an upper ceramic piece are provided inside the upper cover, and the lower cover and the shell body are directly installed in a quick alignment manner through the buckles provided on the lower cover and the card slots opened on the outer surface of the shell body;

[0004] However, this kind of shell for installing alumina ceramic valve cores also has some defects. For example, when acting on the handle to push the handle to displace and rotate, it will cause pressure on the valve core placed inside the cavity. This pressure will be transmitted to the lower cover. And because the lower cover and the shell body are only connected by buckles and card slots, it is very easy to cause the lower cover to be stressed too much, so that the buckles provided on the lower cover are separated from the card slots opened on the outer side of the shell, resulting in the valve core and the lower cover rotating together under force, causing a large torque at the position of the corresponding installation pipeline of the water dispenser, resulting in deformation of the valve core;

[0005] In view of the problems in the above background technique, the utility model aims to provide an alumina ceramic valve core shell. Content of the Utility Model

[0006] The purpose of the utility model is to provide an alumina ceramic valve core shell to solve the problems put forward in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] An alumina ceramic valve core shell, the alumina ceramic valve core shell includes:

[0009] A valve core shell body, a clamping groove is opened on the outer surface of the valve core shell body, and a valve core is installed inside the valve core shell body;

[0010] A top seat is installed at the upper end of the valve core shell body, and an adjusting component for controlling the flow rate of the water source entering the inside of the valve core shell body is arranged inside the top seat;

[0011] A base is installed at the lower end of the valve core housing body. A clamping groove is provided on the outer surface of the lower end of the valve core housing body, and a clamping block is provided at the upper end of the base. At the same time, alignment feet and strengthening feet are also provided at the upper end of the base, and a foot groove and an alignment foot groove are respectively provided at the lower end of the valve core housing body. The number of the provided strengthening feet is four, and the number of the installed alignment feet is two.

[0012] As a further solution of the present utility model: Alignment posts are provided on the outer surface of the base. The number of the alignment posts is two, and the two alignment posts are symmetrically distributed on the outer surface of the base. At the same time, three lower ceramic chips are also provided in the middle of the base surface. The number of the three lower ceramic chips is three, and the three lower ceramic chips are annularly distributed in the middle of the base surface. The outer sides of the three lower ceramic chips distributed on the base surface are sealed and fixed by sealing silica gel.

[0013] As a further solution of the present utility model: The adjusting assembly includes a handle and an upper ceramic chip. The upper ceramic chip is movably installed between the top seat and the valve core housing body, and the upper end of the valve core provided inside the valve core housing body presses against and contacts the upper ceramic chip. At the same time, a handle is provided at the upper end of the upper ceramic chip.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] Compared with the current housing for installing the alumina ceramic valve core, the alumina ceramic valve core housing of the present utility model, through the structural design of four strengthening feet and two alignment feet, enables the base installed at the lower end of the valve core housing body when the adjusting assembly is operating;

[0016] That is, when the operator presses and rotates the position of the handle, the handle pushes the upper ceramic chip to slide and rotate inside the valve core housing body, expanding the water flow gap generated between the upper ceramic chip and the top seat, thereby increasing the water flow rate entering the valve core housing body.

[0017] At the same time, when the upper ceramic chip rotates and displaces, the upper ceramic chip will also press the valve core, causing the valve core to deform and generating a pressure effect on the base. The base, through the cooperation of the four strengthening feet and the two alignment feet provided, enhances the connection stability with the valve core housing body, and then stably transmits this reaction force to the valve core, so that the valve core is not easily subjected to excessive torsion, resulting in deformation problems of the valve core.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] Embodiment

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , an alumina ceramic valve core housing provided in an embodiment of the present utility model, the alumina ceramic valve core housing includes:

[0027] A valve core housing body 3, a card slot is opened on the outer surface of the valve core housing body 3, a valve core 4 is installed inside the valve core housing body 3, and the valve core 4 installed inside the valve core housing body 3 is made of alumina ceramic material; when the valve core 4 installed inside the valve core housing body 3 is assembled with the valve core housing body 3, the valve core 4 is placed in the valve core housing body 3 in an aligned manner and then the valve core 4 is rotated so that the corresponding position on the outer surface of the valve core 4 is aligned and clamped inside the card slot opened on the outer surface of the valve core housing body 3, and thus the locking and fixing of the valve core 4 installed inside the valve core housing body 3 can be achieved;

[0028] At the same time, a top seat 2 is installed at the upper end of the valve core housing body 3, and the provided top seat 2 is used to enclose the upper end of the valve core 4 installed inside the valve core housing body 3; and an adjusting assembly is provided inside the top seat 2, and the provided adjusting assembly is used to control the flow rate of the water source entering the valve core housing body 3.

[0029] In addition, a base 7 is installed at the lower end of the valve core housing body 3. The base 7 installed at the lower end of the valve core housing body 3 is used to seal the lower end of the valve core 4 placed inside the valve core housing body 3. A clamping groove 8 is formed on the outer surface of the lower end of the valve core housing body 3, and a clamping block is provided at the upper end of the base 7. When the base 7 and the valve core housing body 3 are assembled, after the base 7 and the valve core housing body 3 are aligned and installed, the clamping block provided at the upper end of the base 7 is inserted into the clamping groove 8 formed on the outer surface of the lower end of the valve core housing body 3, so as to realize the locking of the base 7 installed at the lower end of the valve core housing body 3. At the same time, a positioning foot 9 and a strengthening foot 6 are also provided at the upper end of the base 7, and a foot groove 5 and a positioning foot groove are respectively formed at the lower end of the valve core housing body 3. After the base 7 and the lower end of the valve core housing body 3 are assembled, the strengthening foot 6 provided at the upper end of the base 7 is inserted into the foot groove 5 formed at the lower end of the valve core housing body 3, and the positioning foot 9 provided at the upper end of the base 7 is inserted into the positioning foot groove formed at the lower end of the valve core housing body 3. The number of the provided strengthening feet 6 is four, and the number of the installed positioning feet 9 is two. Through the structural design of the four strengthening feet 6 and the two positioning feet 9, when the adjusting assembly operates, it is not easy for the valve core 4 to exert a force on the lower end of the base 7, causing the base 7 to exert a reverse force on the valve core 4, resulting in excessive torque of the valve core 4 and causing deformation of the valve core 4.

[0030] Please refer to Figure 3 , in an embodiment of the present invention, two positioning posts 10 are provided on the outer surface of the base 7, and the two positioning posts 10 are symmetrically distributed on the outer surface of the base 7. At the same time, three lower ceramic pieces 11 are further provided in the middle of the base 7 surface, and the three lower ceramic pieces 11 are annularly distributed in the middle of the base 7 surface.

[0031] The provided lower ceramic pieces 11 are used to discharge the water filtered by the valve core 4. In addition to fixing the outer sides of the lower ceramic pieces 11, the installed sealing silicone 12 also ensures the sealing performance when the base 7 at the lower end of the alumina ceramic valve core housing is assembled with the corresponding pipeline of the water dispenser. Moreover, the positioning posts 10 provided on the outer side of the base 7 ensure the quick alignment and installation of the entire alumina ceramic valve core housing with the corresponding pipeline of the water dispenser.

The upper ceramic piece 13 is movably installed between the top seat 2 and the valve core housing body 3, and the upper end of the valve core 4 provided inside the valve core housing body 3 is in pressing contact with the upper ceramic piece 13. At the same time, a handle 1 is provided at the upper end of the upper ceramic piece 13.

[0033] In an embodiment of the present utility model, when the set adjusting component is used to control the water flow rate entering the inside of the valve core housing body 3, the operator presses and rotates the handle 1, so that the handle 1 pushes the upper ceramic sheet 13 to slide and rotate inside the valve core housing body 3, expanding the water flow gap generated between the upper ceramic sheet 13 and the top seat 2, thereby increasing the water flow rate entering the inside of the valve core housing body 3; at the same time, when the upper ceramic sheet 13 rotates and displaces, the upper ceramic sheet 13 will also squeeze the valve core 4, causing the valve core 4 to deform and generate a pressure effect on the base 7; and the base 7 cooperates with the four strengthening feet 6 and the two alignment feet 9 provided, enhancing the stability of the connection with the valve core housing body 3, and then stably transmitting this reaction force to the valve core 4, so that the valve core 4 is not easily subjected to excessive torque, resulting in the problem of deformation of the valve core 4;
