Description

Technical Field

[0001] This utility model belongs to the field of ball valve telescopic adjustment technology, specifically a telescopic ball valve. Background Technology

[0002] Ball valves, whose opening and closing elements are driven by the valve stem and rotate around the ball valve axis, can also be used for fluid regulation and control. Among them, the hard-seal V-type ball valve has a strong shearing force between the V-shaped ball core and the metal valve seat with hard alloy overlay, making it particularly suitable for media containing fibers, small solid particles, etc. Multi-port ball valves can not only flexibly control the merging, splitting, and switching of the flow direction of the media in the pipeline, but also close any channel and connect the other two channels. The pipeline length of ball valves is fixed, and the installation and adjustment flexibility is generally limited.

[0003] Meanwhile, a V-type ball valve with a retractable valve seat is disclosed (announcement number CN221897159U). The valve seat assembly includes an elastic inflatable air bladder and a pressure cap. The inflatable air bladder is generally annular and has an internal air chamber with an opening on one side. The pressure cap is pressed tightly against one side of the inflatable air bladder and covers and seals the opening. A vent hole communicating with the air chamber is opened inside the pressure cap. An inflation / deflation mechanism is also provided outside the valve body, and the inflation / deflation mechanism communicates with the vent hole.

[0004] In the above-mentioned V-type ball valve with a retractable seat, the distance between the valve body and the valve seat is increased by simply inflating the valve to avoid strong friction. However, the structure that usually needs to be retracted is the pipeline position, which requires extending the pipeline to the outside of the increased pipeline for connection. This can only be achieved by adding a new short pipe structure, which reduces the flexibility and convenience of installation.

[0005] Therefore, a retractable ball valve is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a telescopic ball valve, which has the advantages of extending the installation pipeline to meet installation requirements, avoiding the inability to connect to the pipeline, and eliminating the need for additional pipelines.

[0008] The telescopic assembly includes a telescopic tube that slides inside the outlet pipe. One end of the telescopic tube is fixedly provided with a flange, and a guide shaft passes through the edge of the flange. A second flange, which is fixed to the outlet pipe, passes through the outer side of the guide shaft. A valve seat is fixedly provided at the bottom end of the ball valve body.

[0009] Preferably, a reinforcing frame is fixedly provided on the outer side of the telescopic tube, and the reinforcing frame is designed with multiple ports.

[0010] Preferably, the top of the flange one is rotatably provided with an adjusting rod that fits against the flange two.

[0011] Preferably, the bottom end of the adjusting rod is provided with a slot, and the inside of the slot is provided with a locking block that is fixed to the flange.

[0012] Preferably, the upper surface of the adjusting rod is fitted with a pressure block that fits against the flange two, and a screw thread that is helical with the flange two passes through the interior of the pressure block.

[0013] Preferably, the other end of the flange is fixedly provided with a sealing plug that fits against the inner wall of the water outlet pipe.

[0014] Preferably, a spring that fits against the flange is sleeved on the outer side of the adjusting rod.

[0015] Preferably, the valve seat has a threaded shaft spirally arranged inside the bottom end, a base is fixedly arranged at the bottom end of the threaded shaft, a rotating ring is rotatably arranged on the outer side of the base, and a limit frame is fixedly arranged on the outer side of the rotating ring.

[0017] 1. This utility model, through the telescopic tube structure design in the telescopic component, can extend the length of the telescopic tube structure located inside the outlet pipe, so as to meet the situation where the length of some pipes is insufficient during the installation of the ball valve body and additional short pipes are required, thereby improving the flexibility and convenience of the outlet pipe of the ball valve body during installation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The following describes an embodiment of this utility model based on its overall structure.

[0028] like Figures 1 to 4 As shown, this utility model provides a retractable ball valve, including a ball valve body 1, an inlet pipe 2 connected to one side of the ball valve body 1, and an outlet pipe 3 connected to the other side of the ball valve body 1 to facilitate the connection of the ball valve body 1. The outlet pipe 3 also includes a telescopic component 4 inside.

[0029] The telescopic assembly 4 includes a telescopic tube 41 that slides inside the outlet pipe 3. One end of the telescopic tube 41 is fixedly provided with a flange 42. A guide shaft 44 passes through the edge of the flange 42. The telescopic tube 41 can move horizontally on one side of the flange 5 through the flange 42 and the guide shaft 44, thereby completing the opening operation. The outer side of the guide shaft 44 is provided with a flange 5 that is fixed to the outlet pipe 3. A valve seat 6 is fixedly provided at the bottom of the ball valve body 1 to provide a support and stability structure.

[0030] In this embodiment, a reinforcing frame 411 is fixedly provided on the outside of the telescopic tube 41. The reinforcing frame 411 is designed with multiple ports. The multi-port structure design can leave installation space, and the reinforcing frame 411 can protect the flange 42.

[0031] The top of flange 42 is rotatably equipped with an adjusting rod 46 that fits against flange 5. The movement of the adjusting rod 46 can control the movement of flange 42 to complete the stretching or shrinking operation.

[0032] The bottom end of the adjusting rod 46 is provided with a slot 47, and the inside of the slot 47 is provided with a locking block 410 that is fixed to the flange 2 5. The different slots 47 of the adjusting rod 46 are positioned on the outside of the locking block 410 to complete the positioning.

[0033] The upper surface of the adjusting rod 46 is fitted with a pressure block 48 that fits against the flange 2 5. A screw 49 that is spirally connected to the flange 2 5 passes through the inside of the pressure block 48. The screw 49 is inserted and positioned inside the pressure block 48, and the pressure block 48 presses and positions the adjusting rod 46.

[0034] The other end of flange 42 is fixedly provided with a sealing plug 43 that fits against the inner wall of the water outlet pipe 3. The sealing plug 43 seals the inside of the water outlet pipe 3 to maintain the seal after length adjustment.

[0035] A spring 45 is fitted on the outside of the adjusting rod 46 and fits against the flange 2 5. The spring 45 can be cushioned by deforming the adjusting rod 46 and pressing against the flange 2 5.

[0036] The bottom end of the valve seat 6 is provided with a threaded shaft 7, the bottom end of the threaded shaft 7 is fixedly provided with a base 8, the outer side of the base 8 is provided with a rotating ring 9, and the outer side of the rotating ring 9 is fixedly provided with a limiting bracket 10. The rotating ring 9 located below the base 8 can be rotated and adjusted to adjust the installation direction of the limiting bracket 10.

[0037] The working principle and process of a retractable ball valve:

[0038] Initially, the telescopic pipe 41 is housed inside the outlet pipe 3, and the sealing plug 43 tightly fits against the inner wall of the outlet pipe 3, blocking the water flow channel. In use, the inlet pipe 2 is connected to the water source, and the outlet pipe 3 is connected to an external pipe (such as a water supply pipe or equipment interface) via flange 42 of the telescopic pipe 41. Flange 42 and flange 5 are initially positioned via guide shaft 44. When the length of the outlet pipe 3 needs adjustment, the adjusting rod 46 is rotated. Because the groove 47 at the bottom of the adjusting rod 46 engages with the locking block 410 on flange 5, rotating the adjusting rod 46 causes flange 42 to move axially along guide shaft 44, thereby pushing the telescopic pipe 41 to extend or retract within the outlet pipe 3. During this process, the reinforcing frame 411 enhances the structural strength of the telescopic tube 41 to prevent deformation; the spring 45 is sleeved on the outside of the adjusting rod 46 to provide buffering and restoring elasticity during the telescopic process to avoid rigid collisions. When the telescopic tube 41 is adjusted to the required length, the screw 49 is rotated, and the screw 49 is screwed into flange 2 5 to push the pressure block 48 to press the upper surface of the adjusting rod 46, thereby firmly fixing flange 1 42 in the current position to prevent the telescopic tube 41 from shifting during use. At the same time, the sealing plug 43 moves with the telescopic tube 41 and always fits tightly against the inner wall of the water outlet pipe 3 or the external connecting pipe to ensure the sealing of the connection and prevent water leakage.

[0039] Rotate the rotating ring 9 on the outside of the base 8. The rotating ring 9 drives the limiting frame 10 to rotate synchronously. The limiting frame 10 pushes the threaded shaft 7 to rise and fall along the axial direction of the ball valve body 1 through the helical transmission relationship between the threaded shaft 7 and the valve seat 6, thereby controlling the opening or closing of the valve core inside the ball valve, realizing the control of water flow interruption and flow rate. After use, first close the ball valve to cut off the water flow, then rotate the screw 49 in the opposite direction to loosen the pressure block 48. With the help of the spring force 45, retract the telescopic tube 41 into the outlet pipe 3. Finally, disconnect the connecting pipe to complete the device reset.
