[0025] Reference Figure 1-4 As shown, the utility model provides a technical solution: a ceramic rotary valve plunger pump, comprising a pump sleeve 1, the upper port of the pump sleeve 1 is sleeved with a rotary valve stem 2, the lower port of the pump sleeve 1 is sleeved with a pump rod 3, and the side wall of the pump sleeve 1 is connected with a feed pipe 4 and a discharge pipe 5.

[0026] The following is a detailed description of its overall specific settings and functions.

[0027] In this embodiment: the side walls of the feed pipe 4 and the discharge pipe 5 are fixedly connected with a plurality of fixing bars 8, the side walls of the fixing bars 8 are slidably connected with a pressure rod 9, the side walls of the feed pipe 4 and the discharge pipe 5 are provided with external threads 7, the side walls of the external threads 7 are threadedly connected with a driving block 6, and a reserved groove 16 is provided on the inner side of the driving block 6. The driving block 6 with the reserved groove 16 will push the plurality of pressure rods 9 to move to the near side at the same time, wherein the sliding of the pressure rods 9 on the side walls of the fixing bars 8 plays a role in limiting the moving direction of the pressure rods 9.

[0028] The side walls of the feed pipe 4 and the discharge pipe 5 are fixedly connected with circular blocks 10, and the end side of the circular block 10 is fixedly connected with a truncated cone block 11. The two truncated cone blocks 11 are respectively fixedly connected to the side walls of the discharge pipe 5 and the feed pipe 4. The water pipe is pushed further toward the side close to the pump sleeve 1, and the water pipe will be sleeved on the side wall of the circular block 10 along the truncated cone block 11. The side wall of the circular block 10 is provided with a plurality of annular grooves 12. By providing a plurality of annular grooves 12 opened on the side wall of the circular block 10, the sealing effect of sleeved the water pipe on the circular block 10 is further improved.

[0029] Specifically, the outer side of the driving block 6 is provided with anti-skid grooves 15. The anti-skid grooves 15 on the driving block 6 increase the friction between the hand and the driving block 6, and facilitate the twisting work of the driving block 6. A spring 13 is fixedly connected to the surface of the pressure rod 9, and the other end of the spring 13 is fixedly connected to the feed pipe 4 or the discharge pipe 5. When the driving block 6 is rotated in the opposite direction, the pressure rod 9 will be lifted from the water pipe by the elastic force of the spring 13. A plurality of sharp protrusions 14 are fixedly connected to the side wall of the pressure rod 9. The sharp protrusions 14 on the pressure rod 9 will press on the side wall of the water pipe, increasing the friction between the pressure rod 9 and the water pipe.

[0030] Working principle, after the water pipe is sleeved on the outer surface of the feed pipe 4 or the discharge pipe 5, the water pipe is continued to be pushed to the side close to the pump sleeve 1, and the water pipe will be sleeved on the side wall of the circular block 10 along the truncated cone block 11, thereby improving the tightness of the water pipe sleeve. By providing a plurality of annular grooves 12 opened on the side wall of the circular block 10, the sealing effect of sleeved the water pipe on the circular block 10 is further improved. The driving block 6 is rotated, and the anti-slip groove 15 on the driving block 6 increases the friction between the hand and the driving block 6, facilitating the twisting work of the driving block 6. Since a reserved groove 16 is opened on the surface of the driving block 6, the driving block 6 with the reserved groove 16 will push multiple pressure rods 9 to move to the close side at the same time, wherein the sliding of the pressure rods 9 on the side wall of the fixing bar 8 plays a role in limiting the moving direction of the pressure rods 9. At this time, the pointed protrusion 14 on the pressure rod 9 will press on the side wall of the water pipe, increasing the friction between the pressure rod 9 and the water pipe, improving the stability of fixing the water pipe, and thus avoiding the situation where the water pipe slides off the side wall of the feed pipe 4 or the discharge pipe 5 due to excessive water pressure inside the pump sleeve 1, thereby improving the stability of the use of the ceramic rotary valve plunger pump. When the drive block 6 is rotated in the opposite direction, the pressure rod 9 will be lifted from the water pipe by the elastic force of the spring 13, facilitating the extraction of the water pipe located on the surface of the feed pipe 4 or the discharge pipe 5. By setting the above structure, the stability of the water pipe sleeve on the surface of the feed pipe 4 or the discharge pipe 5 is improved, the stability of the ceramic rotary valve plunger pump during use is improved to a certain extent, and the use performance of the ceramic rotary valve plunger pump is improved.
