DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example: As shown in the attached Figures 1 to 5 The gate valve with adjustable connection position shown comprises a valve body 1 , and connecting pipes 2 are arranged at both ends of the valve body 1 .

[0029] Specifically, the valve body 1 includes a valve seat 16, a gate plate 4 disposed in the valve seat 16, and a valve stem 5 rotatably connected to the top of the gate plate 4. The valve stem 5 penetrates the valve seat 16. A nut sleeve 6 is fixedly connected to the top of the valve seat 16. The valve stem 5 is provided with a thread on the outside and is threadedly connected to the nut sleeve 6. A hand wheel is fixedly connected to the outside of the nut sleeve 6. Therefore, the nut sleeve 6 is driven to rotate by turning the hand wheel, so that the gate plate 4 can be driven to rise and fall through the valve stem 5, and then the valve body 1 is opened and closed. A rotating sleeve 9 is provided on the outside of the connecting pipe 2. The rotating sleeve The exterior of 9 is a hexagonal structure, which makes it convenient to drive the rotating sleeve 9 to rotate by a wrench. In addition, a connecting plate 13 is fixedly connected to the exterior of the rotating sleeve 9, and an inclined plate 14 is fixedly connected to the exterior of the connecting plate 13. The outer sides of the ends of the valve body 1 are fixedly connected to spiral plates 3, and the inclined plates 14 are in contact with the exterior of the spiral plates 3. When the rotating sleeve 9 rotates, the inclined plates 14 will contact the spiral plates 3, and as it rotates, the inclined plates 14 also contact the spiral plates 3, so that the valve body 1 and the connecting pipe 2 are in close contact, so that the convex ring 7 can be tightly inserted into the groove 8.

[0030] A groove 8 is provided at the end of the valve body 1, and a convex ring 7 is fixedly connected to one end of the connecting pipe 2. A sealing sleeve is provided on the outer sleeve of the convex ring 7, so as to improve the sealing performance.

[0031] In order to increase the connection effect, an inner ring 10 is fixedly connected to the inner wall of the rotating sleeve 9, a rotating ring 15 is fixedly connected to the outside of the rotating sleeve 9, and outer rings 11 are fixedly connected to both sides of the outside of the valve body 1. The inner side of the inner ring 10 and the outer side of the outer ring 11 are provided with thread grooves 12. The spiral plate 3 and the inclined plate 14 are provided with at least one group. In this embodiment, three groups are provided. Then, the rotating sleeve 9 is rotated, and the rotating sleeve 9 is threadedly connected to the outer ring 11 through the inner ring 10, so that the connecting pipe 2 and the end of the valve body 1 are in conflict. In addition, when the rotating sleeve 9 rotates, the inclined plate 14 will also conflict with the spiral. Due to the spiral setting of the spiral plate 3, the inclined plate 14 will also conflict with the high position of the spiral plate 3 as it rotates, so that the connecting pipe 2 can be tightly in conflict with the valve body 1.

[0032] In order for those skilled in the art to fully understand the technical solution, this embodiment is summarized as follows:

[0033] When in use, the connecting pipe 2 can be rotated, and the position of the external pipeline and the connecting pipe 2 can be adjusted by adjusting the rotation angle of the connecting pipe 2, so as to meet the effects of different environments on the valve body 1;

[0034] For example, if there are two pipes to be connected, and the two pipes are at different heights or left and right positions, the two connecting pipes 2 at both ends of the valve body 1 can be adjusted by rotating them so that the two connecting pipes 2 correspond to the two pipes respectively, and then the connection can be made;

[0035] Then, rotate the rotating sleeve 9, which is threadedly connected to the outer ring 11 through the inner ring 10, so that the connecting pipe 2 and the end of the valve body 1 are in contact. In addition, when the rotating sleeve 9 is rotated, the inclined plate 14 will also contact the spiral. Due to the spiral setting of the spiral plate 3, the inclined plate 14 will also contact the high position of the spiral plate 3 as it rotates, so that the connecting pipe 2 and the valve body 1 can be tightly contacted.

[0036] In summary, in this embodiment, through the rotation setting of the connecting pipe 2, even for two pipelines that are not at the same horizontal position, the valve body 1 can be installed through the rotation adjustment of the connecting pipe 2, thereby increasing the scope of application.
