[0022] Embodiment 1

[0023] Please refer to Figures 1-5 The utility model provides a valve body protective cover device, including control valve 5 and connecting pipe 4, connecting pipe 4 is connected in the both ends of control valve 5, the top of control valve 5 is provided with rotating wheel 51, control valve 5 sets up in lower shell 2, and the upper shell 1 of lower shell 2 is detachably connected with bolt, and the both ends of upper shell 1 and the both ends of lower shell 2 are all set to arc and are inlaid with connecting pipe 4, the top of upper shell 1 is fixedly provided with protective cover 3, and rotating wheel 51 is in the inside of protective cover 3, and the top of protective cover 3 is annularly arrayed with sector observation window 31 around the axis of rotating wheel 51, and the inner chamber top of protective cover 3 is provided with driving assembly 6;

[0024] The both ends of upper shell 1 and the both ends of lower shell 2 are all provided with non-slip pad 7, and non-slip pad 7 is between the shell and connecting pipe 4.

[0025] Specifically, control valve 5 is arranged in lower shell 2, and upper shell 1 is detachably connected with lower shell 2 by bolts, so that control valve 5 is completely wrapped, direct contact of external objects with control valve 5 is blocked, and scratches and depressions on the surface of control valve 5 due to external collision, tool bumping and the like are prevented, and the appearance and strength of the valve body are protected.

[0026] Non-slip pads 7 are arranged between the both ends of upper shell 1 and lower shell 2 and connecting pipe 4, and the both ends of upper shell 1 and lower shell 2 are arranged in an arc shape and inlaid with connecting pipe 4, so that the friction between the shell and connecting pipe 4 is increased, the protective cover device is more stable, and displacement and deflection due to vibration and collision are prevented.

[0027] The top of the protective cover 3 is provided with a plurality of sector-shaped observation windows 31 arranged in a ring around the axis of the rotating wheel 51, which facilitates the operator to observe the state of the rotating wheel 51, such as the position and rotation of the rotating wheel 51, through the observation windows 31, so as to understand the opening and closing state of the valve without opening the protective cover 3, thereby ensuring the protection effect and facilitating the daily inspection and maintenance.

[0028] Further, in order to realize the protection effect of the control valve 5 during the opening and closing process, please refer to Figures 1-5 The driving assembly 6 comprises a rotating handle 61 fixed to the front end of a rotating shaft 62, the rotating shaft 62 is rotatably installed at the top of the inner cavity of the protective cover 3, the middle of the rotating shaft 62 is provided with a worm 63, the worm 63 is engaged with a worm gear 64, the worm gear 64 is rotatably installed at the top of the inner cavity of the protective cover 3 through a rotating rod 65, and the bottom of the worm gear 64 is provided with a plurality of push frames 67 arranged in a ring.

[0029] The push frame 67 is provided with a clamping groove, and a connecting rod is arranged between the rotating wheel 51 and the shaft rod, and the clamping groove of the push frame 67 is matched with the connecting rod.

[0030] The length of the clamping groove in the push frame 67 is greater than the stroke length of the shaft rod of the rotating wheel 51.

[0031] The top of the worm gear 64 is provided with a pointer 66.

[0032] The rotating handle 61 is provided with a notch, the rotating handle 61 is located outside the protective cover 3, and the protective cover 3 is provided with an arc-shaped plate 32 located above the rotating handle 61.

[0033] Specifically, when the control valve 5 needs to be opened or closed, the operator does not need to directly contact the rotating wheel 51, but rotates the rotating handle 61 outside the protective cover 3 through a tool. The rotating handle 61 drives the rotating shaft 62 to rotate, and the worm 63 on the rotating shaft 62 rotates, and the worm 63 is engaged with the worm gear 64, so as to drive the worm gear 64 to rotate. The push frame 67 at the bottom of the worm gear 64 rotates, the clamping groove of the push frame 67 cooperates with the connecting rod between the shaft rod of the rotating wheel 51 to drive the rotating wheel 51 to rotate, thereby realizing the opening or closing of the control valve 5. It can avoid the direct collision, scratching and other damages of the rotating wheel 51 and the control valve 5 caused by the operator during the operation process.

[0034] The length of the clamping groove in the push frame 67 is greater than the stroke length of the shaft rod of the rotating wheel 51, so that the up and down movement of the rotating wheel 51 during the opening and closing process of the control valve 5 can make the connecting rod in the clamping groove, and the push frame 67 pushes the rotating wheel 51 to move.

[0035] The pointer 66 on the top of the worm gear 64 rotates with the rotation of the worm gear 64, and the operator can intuitively understand the opening and closing degree of the control valve 5 by observing the position of the pointer 66. This helps the operator to accurately control the opening or closing state of the control valve 5, avoids the control valve 5 from being excessively opened or closed due to misoperation, and thus guarantees the normal operation and protection effect of the control valve 5;

[0036] The arc-shaped plate 32 is above the handle 61, which can prevent foreign matters and rainwater from directly falling on the handle 61, avoids the handle 61 from being not flexible due to the entry of foreign matters into the rotating mechanism of the handle 61 or the corrosion of rainwater, and further prevents the operator from accidentally touching the handle 61 to cause the misoperation of the control valve 5, thereby further guaranteeing the safe operation of the control valve 5.

[0037] The transmission of the worm gear 64 and the worm 63 has a self-locking characteristic, that is, when the worm 63 stops rotating, the worm gear 64 also stops and remains at the current position, and will not rotate by itself due to external force or internal pressure of the valve. This characteristic can ensure that the control valve 5 can be stably maintained at the specified position after being opened or closed, and prevents the valve from accidentally operating, thereby improving the accuracy and safety of the valve control.

[0038] Working principle: connect the two ends of the connecting pipe 4 and the control valve 5, place the lower shell 2 below the control valve 5, then observe the installation of the upper shell 1 through the observation window 31, the rotating wheel 51 is in the protective cover 3, the connecting rod on the rotating wheel 51 is clamped in the clamping groove, and the upper shell 1 and the lower shell 2 are connected and fixed by bolts, so that the control valve 5 is completely wrapped in the shell, and the protection of the control valve 5 is realized.

[0039] When the control valve 5 needs to be opened or closed, the operator uses a tool to insert the slot on the handle 61 to rotate the handle 61 outside the protective cover 3. The handle 61 drives the rotating shaft 62 to rotate, the worm 63 in the middle of the rotating shaft 62 rotates, the worm 63 meshes with the worm gear 64, and the worm gear 64 rotates. The pusher 67 at the bottom of the worm gear 64 rotates with the worm gear 64, the clamping groove of the pusher 67 cooperates with the connecting rod between the shaft rod of the rotating wheel 51, and drives the rotating wheel 51 to rotate, thereby realizing the opening or closing of the control valve 5. In this process, since the length of the clamping groove in the pusher 67 is greater than the stroke length of the shaft rod of the rotating wheel 51, the connecting rod can be ensured to be always in the clamping groove, so that the pusher 67 can smoothly push the rotating wheel 51 to move;

[0040] When the worm gear 64 is rotated, the pointer 66 on the top of the worm gear 64 will rotate, and the operator can intuitively understand the opening and closing degree of the control valve 5 by observing the position of the pointer 66, so as to accurately control the opening or closing state of the control valve 5 and avoid misoperation.
