[0022] See also Figure 1-3The utility model provides a soft-sealed gate valve device that is easy to replace the gate valve, including a valve body 1, a valve cover 2, a valve plate 3, a valve stem 4, a turntable 5 and a transmission structure 6. The valve cover 2 is installed on the upper side of the valve body 1, and a valve plate 3 is provided in the middle of the valve body 1. The upper end of the valve plate 3 is installed with a valve stem 4. The upper end of the valve stem 4 extends out of the valve cover 2 and is connected to the turntable by transmission. The front side of the valve body 1 is provided with a transmission structure 6. The transmission structure 6 includes a first rotating structure 61, a second rotating structure 62, a pulley group 63, a connecting plate 64 and a baffle 65. The front side of the first rotating structure 61 is connected to the second rotating structure 62 through the pulley group 63. The rotating structure 62 is connected in transmission, and the rear side of the first rotating structure 61 is connected to the second rotating structure 62 through a connecting plate 64. The rear ends of the first rotating structure 61 and the second rotating structure 62 both extend into the valve body 1 and are fixedly connected to the baffle 65. The first rotating structure 61 and the second rotating structure 62 are respectively installed on the left and right sides of the front end surface of the valve body 1. The structures of the first rotating structure 61 and the second rotating structure 62 are consistent, which facilitates the two sets of baffles 65 to rotate at the same time. The baffle 65 has the same diameter as the inner wall of the pipe of the valve body 1, which is beneficial for the baffle 65 to cut off the water flow in the pipe of the valve body 1.

[0023] See also Figure 4 The utility model provides a soft-sealed gate valve device which is convenient for replacing the gate valve. The first rotating structure 61 includes a handle 611, a straight rod 612, a rotating block 613, a circular groove 614 and a pushing structure 615. The straight rod 612 is installed in the middle of the rear end face of the handle 611, and the rotating block 613 is mounted on the outer wall of the straight rod 612. Circular grooves 614 are provided on the upper and right sides of the front end face of the rotating block 613. The inner wall of the upper circular groove 614 fits with the pushing structure 615. The rear end of the straight rod 612 extends into the valve body 1 and is fixedly connected to the baffle 65.

[0024] See also Figure 5 The utility model provides a soft-sealed gate valve device which is convenient for replacing the gate valve. The pushing structure 615 includes a round block 6151, a sliding groove 6152, a rectangular plate 6153 and a limiting rod 6154. The middle part of the front end surface of the round block 6151 is provided with a sliding groove 6152, the rear end surface of the round block 6151 is fixedly connected to the rectangular plate 6153, the middle part of the rectangular plate 6153 is penetrated by the limiting rod 6154, and the rear end of the limiting rod 6154 is fixedly connected to the valve body 1. The outer wall of the round block 6151 fits the inner wall of the circular groove 614, and the inner wall of the circular groove 614 slides with the limiting rod 6154, which is convenient for the round block 6151 to slide along the limiting rod 6154. The outer side of the limiting rod 6154 is covered with a spring 6155, and the rear end surface of the rectangular plate 6153 is elastically connected to the valve body 1 through the spring 6155, which is conducive to driving the rectangular plate 6153 to reset through the resilience of the spring 6155.

[0025] Here's how it works:

[0026] First, the new device is installed at the desired location;

[0027] Second, the staff member pushes the connecting plate 64 backward with one hand, and the connecting plate 64 drives the rectangular plate 6153 to move, and the rectangular plate 6153 drives the round block 6151 to move, and the round block 6151 separates from the rotating block 613, releasing the limit on the rotating block 613. At the same time, the round block 6151 slides along the outer wall of the limiting rod 6154 using the sliding groove 6152, and the rectangular plate 6153 squeezes the spring 6155, causing the spring 6155 to contract.

[0028] Third, the staff member rotates the handle 611 of the first rotating structure 61 or the second rotating structure 62 by 90 degrees with his other hand. The handle 611 drives the straight rod 612 to rotate. The straight rod 612, through the pulley set 63, can synchronously drive the baffle 65 to rotate the first rotating structure 61 and the second rotating structure 62, thereby blocking the water flow in the pipeline of the valve body 1 through the baffle 65.

[0029] Fourth, when the straight rod 612 rotates 90 degrees, the straight rod 612 drives the rotating plate 613 to rotate 90 degrees. By releasing the hand that pushes the connecting plate 64, the rectangular plate 6153 drives the round block 6151 to be stuck into another round groove 614 of the rotating block 613 through the resilience of the spring 6155, thereby limiting the baffle 65. At this time, it is convenient for the staff to replace the valve plate, avoiding the problem of the staff having to close the valve of the external pipeline when repairing the gate valve.
