The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0027] Example 1
[0028] Reference Figure 1 - Figure 4 This embodiment provides an isolation valve anti-maloperation protection cover including a protection component 100, the protection component 100 includes a cover plate 101, a dragging member 102 connected to the cover plate 101, and a baffle 104 fixedly connected to the top of the cover plate 101.
[0029] Furthermore, the cover plate 101 includes an operation port 101a, a slide rail 101b and a closing plate 101c. The operation port 101a is opened at the top of the cover plate 101, the slide rail 101b is embedded in the operation port 101a, and the closing plate 101c is slidably connected to the slide rail 101b.
[0030] Furthermore, the dragging member 102 includes a fixed seat 102a, a first spring 102b and a ramp block 102c, the fixed seat 102a is fixedly connected to the top of the closing plate 101c, one end of the first spring 102b is fixedly connected to the fixed seat 102a, and the other end of the first spring 102b is fixedly connected to the ramp block 102c.
[0031] It should be noted that when the contact block 104a slides to the other side of the inclined block 102c, the first spring 102b is reset. At this time, the fixed block 102a is at the maximum displacement thread in one direction of the slide rail 101b.
[0032] In addition, an anti-skid groove is provided on the top of the fixing seat 102a, and the anti-skid groove can facilitate the staff to drag the fixing seat 102a.
[0033] Furthermore, an arc-shaped clamping plate 102c-1 is fixedly connected to the top of the inclined block 102c.
[0034] Furthermore, a contact block 104a is fixedly connected to one side of the baffle 104, and the contact block 104a is slidably matched with the inclined surface of the inclined surface block 102c.
[0035] Furthermore, the slider 202 includes a second spring 202a, an annular block 202b and a movable column 202c, one end of the second spring 202a is fixedly connected to the slider 202, the other end of the second spring 202a is fixedly connected to the annular block 202b, the movable column 202c is fixedly connected to the bottom of the annular block 202b, and the movable column 202c cooperates with the arc-shaped clamping plate 102c-1.
[0036] When in use, the fixing seat 102a is pushed in the direction away from the baffle 104, which can drive the closing plate 101c to slide in the slide rail 101b, so that the operation port 101a is opened, and the operator can operate the manual automatic switching valve or solenoid valve inside it conveniently through the operation port 101a. The fixing seat 102a is pushed in the direction close to the baffle 104, and the fixing seat 102a drives the inclined surface block 102c to move toward the side of the baffle, so that the contact block 104a moves along the inclined surface of the inclined surface block 102c. During the sliding process, the first spring 102b is compressed. When the contact block 104a slides to the other side of the inclined block 102c, the first spring 102b is reset, thereby locking the inclined block 102c, thereby achieving the effect of limiting the closing plate 101c and locking the closing plate 101c, so as to avoid the opening of the operating port 101a due to the vibration of the manual automatic switching valve or the solenoid valve after the closing plate 101c is closed, thereby reducing the protection effect of the cover plate 101 on the manual automatic switching valve or the solenoid valve.
[0037] Example 2
[0038] Reference Figure 1 - Figure 4 , which is the second embodiment of the utility model, is based on the previous embodiment, and provides an isolation valve anti-misoperation protection cover including a positioning assembly 200, wherein the positioning assembly 200 includes a slide bar 201 fixedly connected to the top of the cover plate 101, a slider 202 slidably connected to the slide bar 201, a limit plate 203 fixedly connected to the top of the cover plate 101, and a mating piece 204 connected to the slider 202.
[0039] Furthermore, the slider 202 includes a second spring 202a, an annular block 202b and a movable column 202c, one end of the second spring 202a is fixedly connected to the slider 202, the other end of the second spring 202a is fixedly connected to the annular block 202b, the movable column 202c is fixedly connected to the bottom of the annular block 202b, and the movable column 202c cooperates with the arc-shaped clamping plate 102c-1.
[0040] It should be noted that when the contact block 104a slides to the other side of the inclined block 102c, the first spring 102b is reset, so that when the inclined block 102c is locked, the movable column 202c is engaged with the arc-shaped clamping plate 102c-1.
[0041] Furthermore, a third spring 203 a is fixedly connected to one side of the limiting plate 203 , and one end of the third spring 203 a is fixedly connected to the slider 202 .
[0042] Furthermore, the fitting 204 includes a connecting rod 204a and a telescopic rod 204b. One end of the connecting rod 204a is fixedly connected to the annular block 202b. Two connecting rods 204a are symmetrically arranged along the center line of the cover plate 101. The telescopic rod 204b is fixedly connected between the two connecting rods 204a.
[0043] Furthermore, a handle 204c is fixedly connected to the upper end surface of the telescopic rod 204b.
[0044] It should be noted that the telescopic rod 204b can be easily operated through the handle 204c.
[0045] When in use, the two handles 204c are pressed in the direction of approaching each other, and the second spring 202a is stretched until the movable column 202c drives the arc clamping plate 102c-1 to move in the direction of the fixed seat 102a, so that the inclined block 102c is not affected by the contact block 104a and moves in the direction away from the baffle 104. At this time, the third spring 203a is stretched. When the operating port 101a is fully opened, the two handles 204c are approached to each other. At this time, the second spring 202a is gradually reset until the first spring 102b is fully reset. At this time, continue to approach the two handles 204c, the second spring 202a is compressed, the movable column 202c is separated from the arc clamping plate 102c-1, the handle 204c is released, and the third spring 203a is reset, which facilitates unlocking the fixed seat 102a, thereby operating through the operating port 101a.
