Description

Technical Field

[0001] The invention relates to the technical field of casing water filling equipment, and in particular to a casing water filling faucet. Background Art

[0002] Casings are tough, translucent films scraped from the large and small intestines of livestock. They are mainly used as outer packaging for sausages. Their basic function is to ensure that sausages do not deteriorate under certain conditions and within a certain period of time to meet the needs of storage and circulation. At present, in the domestic food industry, there are many types of casing products and the demand is also very large. Before using the casings, a lot of related pretreatment work needs to be done, such as cleaning, turning over, scraping, picking up leaks, etc. The first method of cleaning the casings is generally to place the casings in a barrel for stirring and cleaning. The cleaning effect of this method is poor, and debris is easily left on the inner wall of the casings. However, since the casings will be scraped and cleaned for the second time, the requirements for the first cleaning effect are not too high. After scraping the intestines, the mucus on the inner wall of the casings is separated from the inner wall of the casings. The second cleaning needs to be strengthened to ensure that all impurities are cleaned. After the cleaning is completed, the existing casing equipment often needs to fill water into the casings to observe whether there is any leakage. The operator first puts the casing on the existing conventional faucet, and needs to hold the casing with one hand and operate the switch with the other hand, which has the problems of great difficulty in operation, low efficiency, and easy slipping of the hands.

[0018] Example 2

[0019] like Figure 1-Figure 4 A casing water faucet is shown, comprising a valve body 1, a retaining spring 2 is installed inside the front end of the valve body 1, the retaining spring 2 is connected to one end of a spring 3, the other end of the spring 3 is connected to a valve core 4, the valve core 4 is located inside the valve body 1, and the rear end is connected to a water outlet pipe 5, an annular groove 6 is opened at the front end of the valve core 4, a sealing O-ring 7 is installed inside the annular groove 6, four guide holes 8 are opened in the middle of the valve core 4, a valve core inner hole 9 is arranged inside the rear end of the valve core 4, and the valve core inner hole 9 is communicated with the guide hole 8 and the inside of the water outlet pipe 5;

[0020] The valve body 1 has an installation cavity 10, a valve core movement cavity 11 and a water outlet pipe movement cavity 12 respectively formed inside from front to back. The retaining spring 2 and the spring 3 are installed inside the installation cavity 10. A ramp structure 13 is provided between the installation cavity 10 and the valve core movement cavity 11. The ramp structure 13 and the sealing O-ring 7 are in sealing contact. The front end of the water outlet pipe 5 is connected to the rear end of the valve core 4 and is located inside the water outlet pipe movement cavity 12. The water outlet pipe 5 can push the valve core 4 to move back and forth inside the valve core movement cavity 11.

[0021] The front end of the valve body 1 is provided with an external thread 14, which facilitates the valve body 1 to connect to an external water pipe. The inner surface of the installation cavity 10 is provided with a limit transverse groove 15, and the front end of the valve core 4 is provided with a mounting hole 21. A limit pin 20 is installed inside the mounting hole 21, and the end of the limit pin 20 is located inside the limit transverse groove 15. The limit pin 20 cooperates with the limit transverse groove 15 to prevent the valve core 4 from rotating.

[0022] An annular groove 16 is formed inside the valve core movement chamber 11, and a piston O-ring 17 is installed in the annular groove 16. The piston O-ring 17 is sleeved on the valve core 4 and in sealing contact with the valve core 4. Through the sealing O-ring 7 and the piston O-ring 17, the water in the valve body 1 can flow out of the water outlet pipe 5 in a controllable manner.

[0023] A limit plate 18 is provided on the outer side of the front end of the water outlet pipe 5, which can limit the displacement of the water outlet pipe 5 moving forward and facilitate the water outlet pipe 5 to be pushed forward; the diameter of the rear end of the water outlet pipe 5 gradually decreases from front to back, which facilitates the casing to be set on the water outlet pipe 5;

[0024] A locking annular limiting groove 19 is formed on the inner surface of the installation cavity 10 , and the locking annular limiting groove 19 cooperates with the limiting pin 20 to lock the water outlet state.

[0025] The process flow and working principle of the present invention are as follows: when using the faucet, the faucet is connected to the water pipe through the external thread 14, and the end of the casing is put on the water outlet pipe 5. When filling water, the water outlet pipe 5 is pushed forward, and the water outlet pipe 5 drives the valve core 4 to move forward to compress the spring 3. The ramp structure 13 is separated from the sealing O-ring 7, and the water flowing into the installation cavity 10 enters the valve core movement cavity 11. Due to the sealing effect of the piston O-ring 17, the water flows into the water outlet pipe 5 through the guide hole 8 and the inner hole 9 of the valve core, so that the water flows into the casing. When it is necessary to lock the water outlet state, the water outlet pipe 5 is pushed to the front end, the water outlet pipe 5 is rotated, the limit pin 20 enters the locking annular limit groove 19, the valve core 4 is locked, and the water outlet pipe 5 always discharges water; when it is necessary to stop the water, the limit pin 20 is turned back, the water outlet pipe 5 is released, and under the action of the compression spring 3, the valve core 4 drives the water outlet pipe 5 to move backward, so that the slope structure 13 is in sealing contact with the sealing O-ring 7, thereby preventing the water flowing into the installation cavity 10 from entering the valve core movement cavity 11, and the water outlet pipe 5 stops discharging water.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
