DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following further describes in detail the above and other technical features and advantages of the present utility model with reference to the accompanying drawings.
[0020] This embodiment provides a technical solution: A valve cover with a sealing structure, as Figure 1 and Figure 3As shown in the figure, it includes a valve cover 1 and a sealing assembly 2. An annular groove 3 is formed inside the valve cover 1. The annular groove 3 divides the valve cover 1 into two unconnected parts, and the two parts are fixed into one body by an arc-shaped limiting frame 25. The sealing assembly 2 is arranged above the valve cover 1. The sealing assembly 2 includes a sealing member and a replacement member. The sealing member is used to ensure the sealing performance at the connection between the valve cover 1 and the valve body. The replacement member is used to quickly replace the sealing member. When replacing the sealing member, it is not necessary to remove the valve cover 1 from the valve, and the replacement of the sealing member is convenient and fast.
[0021] As Figures 2 - 4 shown, the sealing member includes an arc-shaped sealing strip one 21, an arc-shaped sealing strip two 22 and two sealing strips 23. The arc-shaped sealing strip one 21 and the arc-shaped sealing strip two 22 are clamped in the annular groove 3. Both the arc-shaped sealing strip one 21 and the arc-shaped sealing strip two 22 are T-shaped and are both semi-circular arcs of 180 degrees. The two sealing strips 23 are respectively fixed at both ends of the arc-shaped sealing strip one 21. Sealing grooves 24 are formed at both ends of the arc-shaped sealing strip two 22, and the size of the sealing grooves 24 is adapted to that of the sealing strips 23.
[0022] As Figures 2 - 4 shown, the replacement member includes two arc-shaped limiting frames 25, an arc-shaped plate one 26, an arc-shaped plate two 27, a locking screw 28 and a connecting hole plate 29. The arc-shaped sealing strip one 21 is bonded below the arc-shaped plate one 26. The arc-shaped sealing strip two 22 is bonded below the arc-shaped plate two 27. The two arc-shaped limiting frames 25 are both fixed above the valve cover 1, and they are symmetrically arranged. Thread grooves one 210 are formed on the inner surfaces of the two arc-shaped limiting frames 25. One end of the arc-shaped plate one 26 is hinged to one end of the arc-shaped plate two 27 through a hinge. Thread grooves two 211 are formed on the outer surfaces of the arc-shaped plate one 26 and the arc-shaped plate two 27. A groove 212 is formed at one end of the arc-shaped plate one 26. The locking screw 28 is threadedly installed inside the groove 212. The connecting hole plate 29 is fixed at one end of the arc-shaped plate two 27. The size of the groove 212 is the same as that of the connecting hole plate 29. When the arc-shaped plate one 26 and the arc-shaped plate two 27 are closed, the connecting hole plate 29 just fits into the groove 212. By fixing the connecting hole plate 29 in the groove 212 with the locking screw 28, the arc-shaped plate one 26 and the arc-shaped plate two 27 can be closed and connected.
[0023] When the arc sealing strip 1 21 and the arc sealing strip 2 22 need to be replaced during use, the arc plate 1 26 and the arc plate 2 27 that are connected in a closed manner are first rotated, and the two arc plates are rotated to the upper inner side of the arc limiting frame 25, and the arc sealing strip 1 21 and the arc sealing strip 2 22 are separated from the position of the thread groove 1 210, so that the arc sealing strip 1 21 and the arc sealing strip 2 22 can be brought out of the annular groove 3, and the locking screw 28 is screwed out of the connecting hole plate 29, so that the arc plate 1 26 and the arc plate 2 27 can be opened, and the arc plate 1 26 or the arc plate 27 can be rotated to remove the arc limiting frame 25 to complete the arc sealing strip 1 21 and the arc To remove the arc sealing strip 22, glue the new arc sealing strip 1 21 and the arc sealing strip 22 to the arc plate 1 26 and the arc plate 27, screw the arc plate 1 26 into the two arc limit frames 25, and use the locking screw 28 to lock the connecting hole plate 29 in the groove 212 on the arc plate 1 26, then rotate the arc plate 1 26 until the arc sealing strip 1 21 and the arc sealing strip 22 are tightly stuck in the annular groove 3 to complete the installation, without the need to remove the valve cover 1 as a whole, and the replacement of the arc sealing strip 1 21 and the arc sealing strip 22 is labor-saving, convenient and fast.
[0024] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims of the present invention, but they will all fall within the scope of protection of the present invention.
