Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to a telescopic gate valve. Background Art

[0002] The connection between water pipes requires the use of a medium to connect the pipes and play a role in connecting and cutting off. With the development of science and technology, people have designed gate valves. Gate valves are opening and closing gates. The movement direction of the gate is perpendicular to the direction of the fluid. They are installed between water pipes and are used to cut off or connect the medium in the water pipes. They play a very important role in many industries, such as mining, catering, accommodation, chemical, metal smelting, fire protection and entertainment industries. The internal space is limited by moving the valve plate inside the gate valve, so that the device can switch between the connected state and the cut-off state.

[0003] During the installation of existing gate valves, the distances between pipelines are different. The fixed length of the gate valves requires changing the position of the pipelines during installation to adapt the length of the gate valves. The process of adjusting the pipeline length is cumbersome and therefore does not meet existing needs. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0020] In one embodiment, Figure 1-4 As shown, a retractable gate valve comprises a valve body 1, the top of the valve body 1 is fixedly connected to a shell 2, both ends of the valve body 1 are movably sleeved with connecting pipes 3, the separated ends of the two connecting pipes 3 are fixedly connected with flanges 4, the tops and bottoms of the two connecting pipes 3 are provided with a plurality of threaded holes 5, and the plurality of threaded holes 5 are linearly arranged from left to right, the left and right sides of the top surface and the left and right sides of the bottom surface of the valve body 1 are fixedly connected to a first connecting plate 6, the first connecting plate 6 is fixedly connected to a second connecting plate 7 on a side away from the shell 2, two second connecting plates 7 symmetrically arranged on the upper and lower sides of the connecting pipe 3 are respectively arranged, the top of the second connecting plate 7 is threadedly connected to a fixing bolt 8 on a side away from the shell 2, and the fixing bolt 8 is threadedly sleeved in the threaded hole 5 on a side close to the connecting pipe 3.

[0021] In order to improve the sealing effect when the connecting pipe 3 and the valve body 1 are sleeved, the ports on the left and right sides of the valve body 1 are fixedly connected with the first sealing rings 9. The two first sealing rings 9 are respectively sleeved in the threaded holes 5 on the left and right sides. The first sealing rings 9 are adapted to the inner cavity of the connecting pipe 3, and the first sealing ring 9 is a central opening structure.

[0022] In order to change the original manual twisting method of moving the gate plate 12 up and down to pressing down and pulling up, thereby making the operation more labor-saving and easy, a screw rod 10 is fixedly connected to the top of the shell 2, and the lower end bearing of the screw rod 10 is connected to the first threaded tube 11, the bottom surface of the first threaded tube 11 is fixedly connected to the gate plate 12, and the surface of the gate plate 12 is fixedly connected to the second sealing ring 13, the middle part and the lower side of the gate plate 12 penetrate into the interior of the valve body 1, and the shape of the gate plate 12 is adapted to the shape of the inner cavity of the shell 2, and the top surface of the shell 2 is fixedly connected to a fixing frame 14, and the top of the fixing frame 14 is movably sleeved with a second threaded tube 15, and the second threaded tube 15 is threadedly sleeved on the upper end of the screw rod 10, and the upper end surface of the second threaded tube 15 is fixedly connected to a pressing plate 16, and the middle part of the top surface of the pressing plate 16 is fixedly connected to a handle 17.

[0023] In order to prevent the second threaded tube 15 from rotating due to pulling up and pressing down, which would cause the screw 10 to be unable to rotate, slide grooves 18 are provided on the left and right sides of the inner wall of the outer shell 2, and sliders 19 are fixedly connected to the left and right sides of the surface of the second threaded tube 15 near the lower end. The two sliders 19 are slidably connected in the left and right slide grooves 18 respectively on the side away from the second threaded tube 15.

[0024] Working principle: When the utility model is used, first twist the fixing bolt 8 so that one end of the fixing bolt 8 moves out of the threaded hole 5, then toggle the connecting pipe 3 left and right so that the connecting pipe 3 moves on the left and right sides of the surface of the valve body 1, adjust the connecting pipe 3 to a suitable position, and then reversely twist the fixing bolt 8 so that one end of the fixing bolt 8 is threadedly sleeved in the corresponding threaded hole 5 to fix the connecting pipe 3, so that the device can adjust the length according to actual needs, thereby eliminating the need to adjust the length between pipelines. The operation is simple and practical. When the operating device is turned on, hold the handle 17 upward and pull it. The handle 17 drives the pressing plate 16 to rise, and the pressing plate 16 drives the second threaded tube 15 to rise. Since the second threaded tube 15 is threadedly sleeved with the upper end of the screw rod 10, the second threaded tube 15 will rise when it rises. The drive screw 10 rotates, and the rotation of the screw 10 causes the first threaded tube 11 to rise, and the first threaded tube 11 drives the gate 12 to rise, thereby opening the device and allowing the medium to flow through the valve body 1. Conversely, the palm is pressed on the top surface of the pressing plate 16 to push the pressing plate 16 downward, and the pressing plate 16 drives the second threaded tube 15 to descend. The descent of the second threaded tube 15 causes the screw 10 to reverse, and the reversal of the screw 10 causes the first threaded tube 11 to descend, and the first threaded tube 11 drives the gate 12 to descend, thereby closing the device and cutting off the medium from the valve body 1. By changing the original method of directly manually twisting the screw 10 to rotate to pressing down and pulling up the second threaded tube 15, the drive screw 10 rotates, making it easier to operate the gate 12 to move up and down, which not only reduces the work intensity, but also saves a lot of time.

[0025] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0026] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
