DETAILED DESCRIPTION

[0021] See attached Figures 1 to 9 From the structure shown, it can be understood that an exemplary operation process of preventing backflow of the present application is:

[0022] A smart valve comprises a shell 05 and a stopper shell 09 which are detachably connected by bolts, a plurality of water outlet pipes 10 are formed on the outer end of the stopper shell 09, a connection port 06 is provided at the center of the right end of the shell 05, a water inlet pipe 01 is connected to the connection port 06, a water inlet port 02 is formed on the right end of the water inlet pipe 01, a round platform 03 is formed on the right end of the water inlet port 02, a tension spring is fixedly connected to the round platform 03, a stopper 04 is fixedly connected to the right end of the tension spring, and the stopper 04 can block the water inlet port 02 from the right side; when in use, the fluid can flow through the water inlet port 02. The fluid enters the housing 05 through the water inlet 02 and is then discharged through a plurality of water outlet pipes 10. During this process, the fluid will push open the plug 04 on the left side of the water inlet 02. At this time, the tension spring is stretched by the plug 04, and the plug 04 does not block the water inlet 02, so that the fluid can smoothly enter the housing 05. When the fluid flows back or stops flowing, the tension spring can pull the plug 04 to block the left side of the water inlet 02, thereby preventing the fluid from flowing from the housing 05 into the water inlet 02 and forming a backflow.

[0023] See attached Figures 1 to 9 From the structure shown, it can be understood that an exemplary operation process of reducing the impact force of the present application is:

[0024] A circular hole is provided in the middle of the baffle shell 09, in which a locking tube 14 is provided, and a horn core 12 is fixedly connected to the right end of the locking tube 14, and a water ring 13 is formed on the outer side of the right end of the horn core 12, and the outer side surface of the water ring 13 contacts the inner wall of the shell 05, and a thread is provided on the outer wall of the locking tube 14 and is connected with a nut 15; after the sleeping fluid enters the shell 05, it can be blocked by the middle of the horn core 12, so that the flow flows to the water ring 13, so that the fluid flows to the left after passing through the water ring 13, and the above method can change the flow direction of the fluid in the shell 05, thereby reducing the impact force of its flow, and can reduce the force when the fluid flows out of the valve.

[0025] See attached Figures 1 to 9 From the structure shown, it can be understood that an exemplary operation process of filtering impurities in the present application is:

[0026] The right end face of the water ring 13 is provided with an annular groove, in which a filter screen 20 is embedded, and a pressure ring 08 is formed on the inner wall of the shell 05, which contacts the edge of the filter screen 20 to press the filter screen 20 in the groove; when the fluid flows from right to left through the water ring 13, the filter screen 20 can filter impurities in the fluid, so that the fluid can be obtained as a purer fluid after passing through the valve.

[0027] See attached Figures 1 to 9 From the structure shown, it can be understood that an exemplary operation process of increasing the backflow prevention capability of the present application is:

[0028] The right end of the middle part of the speaker core 12 is slidably connected with a push rod 21, and a spring is fixedly connected between the push rod 21 and the speaker core 12. The right end of the push rod 21 contacts the plug 04, and the push rod 21 can press the plug 04 to the left side of the water inlet 02; as the fluid flows from right to left, when the fluid pushes the plug 04 to move to the left, the plug 04 can push the push rod 21 to the left, so that the push rod 21 compresses the spring, and when the fluid stops, the tension spring can drive the plug 04 to return to its original position and block the left side of the water inlet 02. The spring will also push the push rod 21 to push the plug 04 to move to the right, and can push the plug 04 to block the left side of the water inlet 02, thereby improving the blocking effect on the water inlet 02 and enhancing the effect of preventing backflow.

[0029] See attached Figures 1 to 9 From the structure shown, it can be understood that an exemplary operation process of cleaning impurities in the present application is:

[0030] The outlet pipe 10 is detachably connected with a discharge valve 22; an air cavity 16 is provided inside the horn core 12, an air nozzle 17 is fixedly connected to the left end of the horn core 12, a plurality of air outlets 18 connected to the air cavity 16 are provided on the side wall of the horn core 12, a plurality of tension springs are fixedly connected to the side wall of the horn core 12, an air plug 19 is fixedly connected to the outer end of each tension spring, and the plurality of air plugs 19 can respectively block the plurality of air outlets 18; an arc surface 23 is formed on the right end of the shell 05, a slag discharge valve 07 is fixedly connected to the right end of the shell 05, and the interior of the slag discharge valve 07 is connected to the interior of the shell 05; with long-term use, the right side of the filter 20 The more impurities accumulate, the more the filter 20 will block the fluid. At this time, the air source can be connected to the air nozzle 17, and then high-pressure gas can be introduced into the air cavity 16, so that the gas pushes the multiple air plugs 19 into the shell 05 on the left side of the horn core 12. At this time, the discharge valve 22 is closed and the slag discharge valve 07 is opened, so that the fluid in the shell 05 can flow out from the slag discharge valve 07, so that the gas squeezes out the fluid, and the impurities on the right side of the filter 20 are discharged from the shell 05 during the process of the fluid flowing to the right, so as to achieve the cleaning effect of the filter 20, thereby ensuring the normal use and filtering capacity of the filter 20;

[0031] At the same time, the arc surface 23 can guide the fluid to flow more smoothly toward the slag discharge valve 07, so that the fluid can carry away the impurities;

[0032] In addition, the fluid inside the housing 05 can be squeezed out by introducing gas in the above manner, so that there is no fluid in the housing 05, thereby avoiding the problem of fluid corrosion on the inner wall of the valve when the valve is closed.

[0033] See attached Figures 1 to 9 From the structure shown, it can be understood that an exemplary operation process of improving stability of the present application is:

[0034] The shell 05 and the baffle shell 09 are both made of heat-insulating materials, which can transfer the temperature between the bottom fluid and the outside world, thereby ensuring the temperature stability of the fluid.

[0035] See attached Figures 1 to 9 From the structure shown, it can be understood that an exemplary operation process of extending the fluid route of the present application is:

[0036] The right end face of the water ring 13 is located on the right side of the left end face of the connecting port 06, which can make the fluid form a multi-bending flow form, and can eliminate the impact force in time when the direction of the fluid changes, so as to reduce the impact force of the fluid after passing through the valve.

[0037] See attached Figures 1 to 9 From the structure shown, it can be understood that an exemplary operation process of the present application to avoid deformation is:

[0038] The horn core 12 is made of high-strength metal material, which can avoid deformation when encountering the impact force of the fluid, thereby maintaining stability.
