Description

An adjustable ball valve Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to an adjustable ball valve. Background Technology

[0002] A ball valve is a type of valve that controls the flow of fluid or regulates its flow rate by rotating a ball. Its core component is a ball with a central through-hole, which can be fully opened, fully closed, or partially opened by rotating 90°. It features rapid opening and closing, good sealing performance, and low flow resistance, and is widely used in petroleum, chemical, water treatment, and natural gas industries.

[0003] When installing existing ball valves, the flanges at both ends are in a close fit with the flanges on the pipeline. Furthermore, existing ball valves are integral, meaning the flanges at the ports cannot be adjusted. When the size of the ball valve does not match the pipelines at both ends, the ball valve cannot be installed and used normally. Therefore, existing ball valves without adjustable flange positions are inconvenient to use. To address this, we provide an adjustable ball valve. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing ball valves that do not have the function of adjusting the position of the flange, and to provide an adjustable ball valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable ball valve, comprising: a ball valve body, an adjusting mechanism at one end of the ball valve body, the adjusting mechanism including a tapered end tube, a threaded block on the outer side of the tapered end tube, a threaded rod sleeved inside the threaded block, the threaded rod being threadedly connected to the threaded block, a connecting block sleeved on the outer surface of one end of the threaded rod, an O-ring seal I sleeved inside the ball valve body, an O-ring seal II sleeved inside the ball valve body, a hexagonal block sleeved on the outer surface of the threaded rod, the hexagonal block being fixedly connected to the threaded rod, a limit block being fixedly connected to one end of the threaded rod placed inside the connecting block, and a connecting mechanism at one end of the tapered end tube.

[0006] In a preferred embodiment, the conical end tube is sleeved inside the ball valve body, the conical end tube is slidably connected to the ball valve body, the threaded block is fixedly connected to the ball valve body, the connecting block is fixedly connected to the conical end tube, and the ball valve body has an installation groove inside which O-ring one and O-ring two fit together.

[0007] In a preferred embodiment, the limiting block and the connecting block are rotatably connected, a fixing block is provided on the outside of the conical end tube, the fixing block is fixedly connected to the ball valve body, a guide rod is sleeved inside the fixing block, and the guide rod is slidably connected to the fixing block.

[0008] In a preferred embodiment, the connecting mechanism includes a flange, which is fitted onto the outer surface of the tapered end tube and is fixedly connected to the tapered end tube.

[0009] In a preferred embodiment, the flange is fixedly connected to the guide rod, and bolts are fitted inside the flange, with the bolts slidably connected to the flange.

[0010] In a preferred embodiment, a washer is fitted onto the outer surface of the bolt, and the washer is slidably connected to the bolt.

[0011] In a preferred embodiment, a nut is fitted onto the outer surface of the bolt, and the nut is threadedly connected to the bolt.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention, by setting an adjustment mechanism, allows the position of the connecting mechanism to be changed, thereby enabling the ball valve to connect normally with pipes at a certain distance during actual installation and use, thus improving the applicability of the ball valve installation and making the ball valve more practical. The setting of O-ring one and O-ring two ensures that the connection between the conical end pipe and the ball valve body remains sealed, preventing water leakage between the conical end pipe and the ball valve body. Furthermore, the setting of a threaded rod, which can rotate and move, allows the conical end pipe to be moved, making the position of the connecting mechanism more suitable.

[0023] 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.

[0024] Example 1

[0025] As shown in Figures 1-4, this utility model provides a technical solution: an adjustable ball valve, comprising: a ball valve body 1, an adjusting mechanism 2 at one end of the ball valve body 1, the adjusting mechanism 2 including a tapered end tube 21, a threaded block 22 on the outer side of the tapered end tube 21, a threaded rod 23 sleeved inside the threaded block 22, the threaded rod 23 being threadedly connected to the threaded block 22, a connecting block 24 sleeved on the outer surface of one end of the threaded rod 23, an O-ring 25 and an O-ring 26 sleeved inside the ball valve body 1, and a hexagonal block 27 sleeved on the outer surface of the threaded rod 23, the hexagonal block 27 being fixedly connected to the threaded rod 23. One end of the connecting block 24 is fixedly connected to a limiting block 28. One end of the tapered tube 21 is provided with a connecting mechanism 3. The tapered tube 21 is sleeved inside the ball valve body 1 and is slidably connected to the ball valve body 1. The threaded block 22 is fixedly connected to the ball valve body 1. The connecting block 24 is fixedly connected to the tapered tube 21. The ball valve body 1 has an installation groove for O-ring 25 and O-ring 26 to fit together. The limiting block 28 is rotatably connected to the connecting block 24. The tapered tube 21 has a fixing block 29 on its outer side. The fixing block 29 is fixedly connected to the ball valve body 1. The fixing block 29 has a guide rod 201 sleeved inside it and is slidably connected to the fixing block 29.

[0026] In this embodiment, by providing a tapered end tube 21 with a tapered end, the tapered end tube 21 can compress the O-ring 25 and O-ring 26 when it enters the ball valve body 1, causing them to deform. This allows the O-rings 25 and 26 to fill the gap between the tapered end tube 21 and the ball valve body 1, maintaining a sealed connection between the ball valve body 1 and the tapered end tube 21. Simultaneously, a threaded block 22 and a threaded rod 23 are provided, with the threaded rod... 23 is threadedly connected to the threaded block 22, and the threaded rod 23 can rotate and move with the cooperation of the threaded block 22. Thus, the threaded rod 23 can drive the connecting block 24 and the tapered tube 21, so that the tapered tube 21 can slide, thereby changing the position of the connecting mechanism 3. At the same time, a fixed block 29 and a guide rod 201 are provided, and the guide rod 201 can slide with the tapered tube 21. Thus, with the cooperation of the fixed block 29, the guide rod 201 can guide the tapered tube 21, so that the tapered tube 21 will not rotate or move.

[0027] Example 2

[0028] As shown in Figures 1-4, the connecting mechanism 3 includes a flange 31, which is fitted onto the outer surface of the tapered end tube 21 and is fixedly connected to the tapered end tube 21. The flange 31 is also fixedly connected to the guide rod 201. A bolt 32 is fitted inside the flange 31 and is slidably connected to the flange 31. A gasket 33 is fitted onto the outer surface of the bolt 32 and is slidably connected to the bolt 32. A nut 34 is fitted onto the outer surface of the bolt 32 and is threadedly connected to the bolt 32.

[0029] In this embodiment, a connecting mechanism 3 is provided, which enables the ball valve body 1 to be connected to the pipe to be connected. Bolts 32 and nuts 34 are provided, and the bolts 32 and nuts 34 are threadedly connected. Under the action of bolts 32 and nuts 34, the flange 31 can be tightly and firmly connected to the flange plate fixedly connected to the pipe. Hexagonal block 27 is provided, which makes the threaded rod 23 more convenient to rotate.

[0030] Working principle:

[0031] As shown in Figures 1-4, when using this utility model, if it is necessary to adjust the position of the flange 31, an auxiliary tool suitable for the hexagonal block 27 can be used to rotate the hexagonal block 27. At this time, the hexagonal block 27 can drive the threaded rod 23 to rotate, and the threaded rod 23 can rotate and move with the cooperation of the threaded block 22. At this time, the threaded rod 23 can drive the limiting block 28 to rotate inside the connecting block 24. Then, under the action of the threaded rod 23, the tapered end tube 21 can slide inside the ball valve body 1. At this time, the tapered end tube 21 can be squeezed by the O-ring 1 25 and the O-ring 26, causing the O-ring 1 25 and the O-ring 26 to deform. The sealing ring 26 fills the gap between the conical end pipe 21 and the ball valve body 1. At the same time, the conical end pipe 21 moves the flange 31 until the flange 31 is in the correct position. The guide rod 201 slides inside the fixing block 29 and guides the conical end pipe 21, so that the flange 31 can approach the pipe to be connected without deviation. When the flange 31 is in contact with the flange plate connected to the pipe, the ball valve body 1 can be installed. At this time, the bolt 32 passes through the flange 31 and other flange plates, and the gasket 33 is fitted onto the outer surface of the bolt 32. Finally, the nut 34 is threaded to the bolt 32 until the ball valve body 1 can be securely connected to the pipe.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
