It consists of two flange plates and a sealing gasket in the middle, and is usually fastened by bolts. When the sealing gasket inside the globe valve needs to be replaced and maintained later, the bolts and nuts used to fix the pipeline and the outside of the valve body need to be unscrewed one by one, and the removed bolts and nuts are often prone to loss, and the overall operation steps are more cumbersome, time-consuming and laborious.

[0020] Please refer to Figures 1-3 , the present invention provides a technical solution for an easy-to-operate manual globe valve: including:
[0021] Globe valve body 1, sealing rings 8 are connected to both the left and right sides of the globe valve body 1, a connecting pipe 7 is connected to the outside of the sealing ring 8, a first housing 3 and a second housing 5 are correspondingly sleeved on the outside of the connecting pipe 7 and the sealing ring 8, locking mechanisms are arranged on both the upper and lower sides of the first housing 3 and the second housing 5, and two clamping mechanisms are arranged on the inner sides of the first housing 3 and the second housing 5.
[0022] As Figures 1 to 3 shown, the locking mechanism includes a clamping seat 4 and a U-shaped plate 2. The bottom of the clamping seat 4 is fixedly connected to the second housing 5, the bottom of the U-shaped plate 2 is fixedly connected to the first housing 3, a U-shaped card slot 18 is opened at the top of the clamping seat 4, shaft rods 9 are rotatably connected to both side arms of the U-shaped plate 2, a second screw 16 is fixedly connected to the outside of the shaft rod 9, and a sheep's horn nut 17 is threadedly connected to the outside of the second screw 16. The first housing 3 and the second housing 5 are sleeved on the outside of the valve body and the connecting pipe 7, and the second screws 16 on both the upper and lower sides of the first housing 3 are inserted into the clamping seats 4 on both the upper and lower sides of the second housing 5, and the two side sheep's horn nuts 17 are rotated to tightly connect the first housing 3 and the second housing 5 together, increasing the stability among the valve body, the sealing ring 8 and the connecting pipe 7.
[0023] As Figure 3 shown, bearings 10 are embedded in both side arms of the U-shaped plate 2, and the inner rings of the bearings 10 are fixedly connected to the shaft rods 9. Under the connection action of the bearings 10 and the shaft rods 9, it is beneficial for the second screw 16 to rotate flexibly.
[0024] As Figure 3As shown in the figure, a sealing ring 15 is sleeved on the outer side of the second screw 16 near the position of the horn nut 17, and the outer diameter of the sealing ring 15 is larger than the radius of the bottom of the U-shaped card slot 18. By setting the sealing ring 15, it is beneficial to increase the stability between the first housing 3 and the second housing 5. By setting the outer diameter of the sealing ring 15 to be larger than the radius of the bottom of the U-shaped card slot 18, it is beneficial to prevent the sealing ring 15 from detaching from the bottom of the U-shaped card slot 18.
[0025] As Figure 3 shown in the figure, the position of the second screw 16 corresponds to the position of the U-shaped card slot 18, and the outer diameter of the horn nut 17 is larger than the radius of the bottom of the U-shaped card slot 18.

The shaft holes 11 are threadedly connected with the first screw 14. By rotating the rotating wheel 6 clockwise, through the connection between the shaft hole 11 and the first screw 14, it is beneficial to drive the pressing plate 12 to move forward. On the contrary, by rotating the rotating wheel 6 counterclockwise, it is beneficial to drive the pressing plate 12 to move backward.
[0028] The working principle of the present utility model is as follows: The first housing 3 and the second housing 5 are sleeved on the outer sides of the valve body and the connecting pipe 7, and the second screws 16 on the upper and lower sides of the first housing 3 are inserted into the clamping seats 4 on the upper and lower sides of the second housing 5, and the horn nuts 17 on both sides are rotated to tightly connect the first housing 3 and the second housing 5 together, so as to increase the stability between the valve body, the sealing ring 8 and the connecting pipe 7. By setting the sealing ring 15, it is beneficial to increase the stability between the first housing 3 and the second housing 5. Subsequently, rotate the rotating wheel 6. Through the connection between the shaft hole 11 and the first screw 14, it is beneficial to drive the pressing plate 12 to move forward, so as to firmly press the pressing plate 12 against the outer wall of the connecting pipe 7 and increase the sealing performance between the valve body, the sealing ring 8 and the connecting pipe 7. On the contrary, when it is necessary to remove the sealing ring 8, only need to rotate the horn nut 17 and the rotating wheel 6 in the reverse direction.
[0029] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
