[0025] The utility model provides Figure 1-4The easy-to-clean one-way valve shown in the figure includes a one-way valve body 1, the left and right ends of the one-way valve body 1 are respectively a fluid outlet 3 and a fluid inlet 2, and an inner cavity 4 is provided inside the one-way valve body 1, and the inner cavity 4 is connected to the fluid outlet 3 and the fluid inlet 2, so that the fluid can pass through the one-way valve body 1, the inner thread of the one-way valve body 1 is connected to a spring seat 5, the outer ring of the spring seat 5 is provided with a thread 6, and the spring seat 5 is movably connected to a spring 7, and the end of the spring 7 is fixedly connected to a sealing block 8, so that the spring seat 5, the spring 7 and the sealing block 8 can be removed, so as to ensure that the subsequent cleaning and maintenance work inside the one-way valve body 1 can be carried out smoothly, and further includes:

[0026] The mounting assembly 9 has a mounting opening 910 provided inside the spring seat 5, and a mounting plate 901 is movably installed inside the mounting opening 910, a protrusion 902 is fixedly connected to one end of the mounting plate 901, and the protrusion 902 matches the limiting groove 903, and the limiting groove 903 is communicated with the mounting opening 910, a movable groove 909 is provided inside the mounting plate 901, and a clamping block 904 is movably connected to the movable groove 909 through a spring 2 907, and the clamping block 904 matches the engaging groove 905, and the engaging groove 905 is communicated with the mounting opening 910, so as to facilitate the installation of the spring seat 5, the spring 1 7 and the sealing block 8.

[0027] The inner cavity 4 is conical, and the surface of the inner cavity 4 is smooth, and the inner wall of the inner cavity 4 is in sliding connection with the sealing block 8, ensuring that after the fluid enters the inner cavity 4 through the fluid inlet 2, it can push against the sealing block 8 to move so that the fluid inside the inner cavity 4 flows smoothly.

[0028] The sealing block 8 is made of silicone, and in the initial state, the outer wall of the sealing block 8 fits with the inner wall of the tapered inner cavity 4, ensuring that the fluid can push against the sealing block 8 and move toward the fluid outlet 3 after entering the inner cavity 4 through the fluid inlet 2. At this time, the gap between the sealing block 8 and the inner cavity 4 can ensure the smooth passage of the fluid. At the same time, if backflow occurs, the fluid force pushes against the sealing block 8 so that the sealing block 8 blocks the fluid inlet 2, preventing the reverse fluid from passing through the one-way valve body 1.

[0029] The surface of one side of the spring seat 5 where the engaging groove 905 is provided is provided with an inclined surface 911 , and the inclined surface 911 is in contact with the end of the engaging block 904 to achieve a sliding connection.

[0032] Working principle: When using an easy-to-clean one-way valve, the fluid first enters the inner cavity 4 through the fluid inlet 2 and can move against the sealing block 8 toward the fluid outlet 3. At this time, the gap between the sealing block 8 and the inner cavity 4 can ensure the smooth passage of the fluid. At the same time, if reverse flow occurs, the fluid force pushes against the sealing block 8 so that the sealing block 8 blocks the fluid inlet 2, preventing the reverse flow of the fluid from passing through the one-way valve body 1.

[0033] When it is necessary to clean the inside of the one-way valve body 1, the spring seat 5 is twisted to drive the spring seat 5, spring 1 7 and sealing block 8 to be separated from the one-way valve body 1. The spring seat 5, spring 1 7 and sealing block 8 are then pulled out through the fluid outlet 3 to clean the inside of the one-way valve body 1. The pulled-out parts such as the spring seat 5, spring 1 7 and sealing block 8 can be cleaned and maintained separately to ensure the service life of the one-way valve body 1.

[0035] When installing the mounting plate 901 and the mounting port 910, the mounting plate 901 moves toward the mounting port 910, and the inclined surface 911 presses against the end of the clamping block 904 and pushes the clamping block 904 to move toward the inside of the movable groove 909 until the clamping block 904 matches the engaging groove 905 as the mounting plate 901 moves. The spring 2 907 applies force to push the clamping block 904 to match the engaging groove 905 to complete the installation of the mounting plate 901 and the spring seat 5. Then, the spring seat 5, spring 1 7 and sealing block 8 can be installed into the inside of the one-way valve body 1 from the fluid outlet 3.
