The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1 and Figure 4 , which is the first embodiment of the utility model, provides a protective cover, which includes a cover body 100 and an operating assembly 200 embedded in the cover body 100. The cover body 100 is fixed to the outside of the valve handle of the isolation valve by bolts at the bottom, and the stress on the entire protective cover can be eliminated by ribs arranged in an array between the bolts.

[0032] A fixing plate 101 is arranged on one side of the cover body 100 opposite to the handle. The fixing plate 101 is arranged as a whole inside the cover body 100, which is equivalent to a layer of partition inside the cover body 100. The fixing plate 101 is arranged parallel to the side of the cover body 100 opposite to the valve handle of the isolation valve. The fixing plate 101 is provided with a receiving hole 101a just above the valve stem of the isolation valve to receive the operating component 200, and a fixing groove 101b is arranged on the hole wall of the receiving hole 101a.

[0033] The operating assembly 200 includes a rotating member 201 and a hand-held member 202, wherein the rotating member 201 as a whole is composed of a rotating ring 201a and a limiting groove 201b fixedly arranged in the direction of the handle. The rotating member 201 is fixed on the fixed plate 101, so that the rotating member 201 can only rotate in the receiving hole 101a, and cannot move in other directions. The limiting groove 201b of the rotating member 201 covers the valve handle of the isolation valve, and the limiting groove 201b can be driven to rotate by the rotation of the rotating ring 201a, thereby realizing the rotation of the valve handle.

[0034] Furthermore, a hand-holding piece 202 is concentrically arranged on one side of the rotating piece 201 away from the valve handle of the isolation valve. The hand-holding piece 202 can provide a hand support point for the staff. The hand-holding piece 202 is pressed to cooperate with the rotating piece 201, and then the hand-holding piece 202 is rotated to drive the rotating piece 201 to rotate, which is then used for opening and closing the valve.

[0035] In summary, this design installs the operating components on the protective cover so that the staff can open and close the valve without opening the protective cover, and external dust cannot enter the protective cover, ensuring that the isolation valve is not affected by dust.

[0036] Example 2

[0037] Reference Figure 1~Figure 4 , which is the second embodiment of the utility model, and is different from the first embodiment in that: it also includes. In the previous embodiment, the protective cover includes a cover body 100, and the cover body 100 is fixedly arranged around the isolation valve handle;

[0038] The operating assembly 200 is embedded in the cover body 100 and includes a rotating member 201 disposed outside the isolation valve handle and a hand-held member 202 disposed on a side of the rotating member 201 away from the handle.

[0045] Furthermore, a guide key 202b-1 is provided in the middle of the handle 202b, and the handle 202b is sleeved on the guide column 201a-2 through the guide key 202b-1.

[0046] Furthermore, an elastic member 203 is disposed outside the guide column 201 a - 2 , one end of the elastic member 203 abuts against the rotating member 201 , and the other end abuts against the hand-holding member 202 .

[0047] It should be noted that the cover 100 is fixed by bolts at the bottom and fixed to the outside of the valve handle of the isolation valve. A fixing plate 101 is provided on the side of the cover 100 opposite to the handle. The fixing plate 101 is provided inside the cover 100 as a whole, which is equivalent to a layer of partition in the cover 100. The fixing plate 101 is provided in parallel with the side of the cover 100 opposite to the valve handle of the isolation valve. The fixing plate 101 is provided with a receiving hole 101a just above the valve stem of the isolation valve, which can accommodate the operating component 200. A fixing groove 101b is provided on the hole wall of the receiving hole 101a. A wire inlet hole 103 is provided on the side wall of the cover 100. The power cord of the isolation valve enters the protective cover from the wire inlet hole 103. A brush is provided on the edge of the wire inlet hole 103 for protection to prevent dust from entering the protective cover from the wire inlet hole 103.

[0048] Preferably, the operating assembly 200 includes a rotating member 201 and a hand member 202, the rotating member 201 is composed of a rotating ring 201a and a limiting groove 201b arranged in the direction of the handle, a first tooth 201 is cut on a side of the rotating ring 201a away from the handle, a guide column 201a-2 is arranged on the axial inner side of the first tooth 201, and the guide column 201a-2 faces the side of the hand member 202.

[0049] The limiting groove 201b fixes the valve handle of the isolation valve from top to bottom, so that when the rotating member 201 rotates, the limiting groove 201b can be driven to rotate, and then the limiting groove 201b drives the handle to rotate, and the convex ring 201a-3 at the large diameter end of the rotating ring 201a cooperates with the fixed groove 101b, so that the rotating ring 201a can only rotate in the fixed groove 101b without disengaging, and at the same time, the large diameter of the rotating ring 201a is in contact with the side wall of the accommodating hole 101a, and a first annular tooth 201a-1 is provided on the side of the rotating ring 201a away from the valve stem of the isolation valve, and a guide column 201a-2 is provided on the axial inner side of the first tooth 201a-1.

[0050] A hand-held member 202 is sleeved on the guide column 201a-2, wherein the hand-held member 202 includes a force disk 202a and a handle 202b on the force disk 202a, the force disk 202a is sleeved on the guide column 201a-2 in the middle, the handle 202b is arranged on the side away from the rotating member 201, and a second annular tooth 202a-1 is arranged on the side of the force disk 202a close to the rotating ring, the second tooth 202a-1 is complementary to the first tooth 201a-1, and when the two are complementary to each other, they limit each other so that the hand-held member 202 and the rotating member 201 rotate synchronously.

[0051] A guide key 202b-1 is provided in the middle of the handle 202b to play a positioning role. The guide key 202b-1 is sleeved in the guide column 201a-2. An elastic member 203 is sleeved on the outside of the guide column 201a-1. One end of the elastic member 203 abuts against the rotating member (201), and the other end abuts against the hand-holding member (202). It is ensured that when the hand-holding member 202 is pressed downward, it can be reset by the elastic member 203, and a retaining ring is also provided on the outer wall of the protective cover to prevent the hand-holding member 202 from being separated. A notch is also provided on the handle 202b for easy hand grasping.

[0052] When in use, the staff holds the handle 202b with their hands and presses the hand-held member 202 in the direction of the valve. The second latch tooth 202a-1 on the force disk 202a is close to the first latch tooth 201a-1. Even if the second latch tooth 202a-1 and the first latch tooth 201a-1 are opposite to each other, they only need to be rotated once to complement each other. At this time, the hand-held member 202 is rotated, and the rotating member 201 also rotates under the mutual limitation of the second latch tooth 202a-1 and the first latch tooth 201a-1. The rotating ring 201a rotates in the fixed groove 101b, and the limiting groove 201b drives the isolation valve handle to rotate to realize the opening and closing of the valve.

[0053] In summary, this design enables the adjustment of the valve without opening the protective cover, and even if the hand piece 202 is pressed, no gap will be formed on the protective cover, thereby ensuring the airtightness of the protective cover and preventing external dust from entering the cover and affecting the isolation valve.
