[0026] Embodiment 1

[0027] like Figure 1 As shown:

[0028] A fluid control valve comprises a valve 1.

[0029] In this embodiment: the existing {public announcement number}: CN218670706U discloses a fluid control valve; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the control component of the device lacks a protective structure, so after a long period of use, its top may be affected by external forces and damaged, or eroded by rainwater and cause rust, thereby affecting the overall service life and being detrimental to normal use and work", in terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve the above problems, a controller 2 and a rotating trough 3 are added on this basis.

[0030] More specifically:

[0032] In combination with the above content: it also includes a controller 2, a rotating groove 3, a connecting ring 4, a protective cover 5, an A connecting column 6, a B connecting column 7 and a retaining ring 8 arranged on one side of the valve 1, the controller 2 is fixedly installed on the surface of the valve 1, and the surface of the valve 1 is also provided with a rotating groove 3 rotatably connected to the connecting ring 4, and a protective cover 5 is also fixedly installed on the surface of one side of the connecting ring 4, the surface of the protective cover 5 is fixedly installed with an A connecting column 6, and the A connecting column 6 and the B connecting column 7 are fitted and connected, and the B connecting column 7 is fixedly installed on the surface of the protective cover 5, and the surface of the B connecting column 7 is also rotatably connected to the retaining ring 8.

[0033] In this embodiment: when it is necessary to protect the controller 2, the connecting ring 4 and the protective cover 5 can be rotated along the rotating groove 3. At this time, the two protective covers 5 on both sides of the controller 2 will move toward the direction of the controller 2. When the two protective covers 5 are connected, the A connecting column 6 and the B connecting column 7 are also closed. Then, the B connecting column 7 and the snap ring 8 can be rotated. The snap ring 8 will gradually rotate along the surface of the B connecting column 7 to the position of the A connecting column 6. After the connection is formed between the A connecting column 6 and the snap ring 8, the snap ring 8 will fix the positions of the A connecting column 6 and the B connecting column 7 to avoid separation between the two, so that the protective cover 5 can remain in a closed state, thereby achieving the purpose of polarity stable protection of the controller 2.

[0034] Going further:

[0035] In an optional embodiment, the shape of the valve 1 is a bilaterally symmetrical geometric body.

[0036] In this embodiment: the valve 1 symmetrical on both sides can provide the rotating groove 3 and the connecting ring 4 with a sufficiently stable installation space, and the connecting ring 4 and the protective cover 5 can effectively rotate along the axis of the valve 1, thereby enabling the controller 2 arranged above the valve 1 to be effectively protected.

[0037] Going further:

[0038] In an optional embodiment, the rotation grooves 3 are symmetrically arranged on the surface of the valve 1 and on both sides.

[0039] In this embodiment, the rotation grooves 3 symmetrically arranged on the surface of the valve 1 can form a stable connection with the connecting ring 4, thereby ensuring that the connecting ring 4 and the protective cover 5 can maintain a stable state.

[0040] Going further:

[0041] In an optional embodiment, the connecting rings 4 are symmetrically arranged on both sides of the surface of the valve 1 , and the positions of the connecting rings 4 match the positions of the rotating grooves 3 .

[0042] In this embodiment, the connecting rings 4 symmetrically arranged on both sides of the surface of the valve 1 can form a stable connection with the protective cover 5, and driven by the connecting rings 4, the protective cover 5 can be placed on the top of the controller 2 to protect the controller 2.

[0043] Going further:

[0044] In an optional embodiment, two protective covers 5 are provided, and the two protective covers 5 are arranged on the outside of the controller 2 .

[0045] In this embodiment, the two protective covers 5 arranged on both sides of the controller 2 can stably shield the controller 2, thereby ensuring that the controller 2 is not corroded by external force or moisture, thereby extending its service life.

[0046] Going further:

[0047] In an optional embodiment, the A connecting column 6 and the B connecting column 7 are in the shape of a half-cut cylinder, and the A connecting column 6 and the B connecting column 7 are arranged on different surfaces of the protective cover 5 .

[0048] In this embodiment, the A connecting column 6 and the B connecting column 7 which are arranged in a half-cylindrical shape can be connected to the two protective covers 5 respectively, so that the two protective covers 5 can complete the docking work when they are connected.

[0049] Going further:

[0050] In an optional embodiment, the shape formed by the A connecting column 6 and the B connecting column 7 is a cylindrical geometric body with an annular groove on the surface.

[0051] In this embodiment: the cylindrical geometric body composed of the A connecting column 6 and the B connecting column 7 can form an effective connection between the retaining ring 8 and the two, and can enable the retaining ring 8 to produce stable rotation on the surfaces of the two, and then when the retaining ring 8 rotates to one side of the A connecting column 6, the polarity of the two can be positioned to avoid separation.

[0052] Going further:

[0053] In an optional embodiment, the shape of the snap ring 8 is a circular ring with a notch, and the length of the snap ring 8 is greater than half of the circumference of the circular ring where it is located.

[0054] In this embodiment: the annular clamping ring 8 can fix the connection between the A connecting column 6 and the B connecting column 7 when they are connected at the same time, so that the two protective covers 5 can always form a stable connection, ensuring that the controller 2 can obtain stable protection.

[0055] The working principle and usage process of the present invention are as follows: when it is necessary to protect the controller 2, the connecting ring 4 and the protective cover 5 can be rotated along the rotating groove 3. At this time, the two protective covers 5 on both sides of the controller 2 will move toward the direction of the controller 2. When the two protective covers 5 are connected, the A connecting column 6 and the B connecting column 7 are also closed. Then, the B connecting column 7 and the snap ring 8 can be rotated. The snap ring 8 will gradually rotate along the surface of the B connecting column 7 to the position of the A connecting column 6. After the connection is formed between the A connecting column 6 and the snap ring 8, the snap ring 8 will fix the positions of the A connecting column 6 and the B connecting column 7 to avoid separation between the two, so that the protective cover 5 can remain in a closed state, thereby achieving the purpose of polarity stable protection of the controller 2.
