Description

Technical Field

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

[0002] Ball valves are widely used in industries such as petroleum refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, power, municipal engineering, and steel, playing a crucial role in the national economy. High-pressure ball valves are mainly used to cut off or connect the medium in pipelines, and can also be used for fluid regulation and control. Chinese patent CN202746637U discloses a ball valve, which includes a main valve body, a secondary valve body, a ball core, an inlet valve seat, an outlet valve seat, a valve stem, and a packing section. At least one of the inlet valve seat and the outlet valve seat is in direct contact with the ball core. When this ball valve is used in high-pressure devices, such as hydraulic machinery, hydraulic switches, and many high-pressure equipment for natural gas, the requirements for the ball valve are extremely high. During use, when the valve stem opens instantaneously, the instantaneous impact force of the fluid on the ball core is very large, causing damage to the surface of the ball core, eventually leading to the scrapping of the entire ball valve. Therefore, there is an urgent need for a ball valve that can dampen the instantaneous impact of fluid generated when the valve is opened.

[0003] The announcement number CN210661452U discloses a divertable ball valve, including a main valve body and a secondary valve body. The main valve body includes a valve stem cavity and a ball core. A first channel is provided between the valve stem cavity and the water inlet of the main valve body. The secondary valve body is provided with a second channel that connects and communicates with the main valve body. The first channel and the second channel are connected and communicate with the valve stem cavity.

[0004] When in use, the existing device is manufactured as a single piece. If the ball valve needs maintenance, the pipeline needs to be disassembled, which results in low working efficiency and can easily damage the ball valve when the water pressure is high. Therefore, we propose a divertable ball valve. Utility Model Content

[0013] As a further improvement to the above solution, a slot is provided on the rear side of the ball valve mounting seat, the locking block fits into the slot, and a sealing ring is fixedly installed at the bottom of the ball valve mounting seat, the sealing ring fitting into the valve seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] (1) A divertable ball valve of this utility model is provided by sliding the ball valve mounting seat into the inner side of the mounting bracket. After the ball valve mounting seat is slid in, the first spring can drive the limiting plate to slide. The limiting plate can limit and lock the ball valve mounting seat.

In this embodiment, first springs 10 are fixedly mounted at the four corners of the rear inner wall of the mounting frame 5, limit plates 11 are fixedly mounted on the front side of the first springs 10, and fixing plates 12 are fixedly mounted on the left and right inner walls of the mounting frame 5. A second spring 13 is fixedly installed on one side of the ball valve mounting seat 6, and a locking block 14 is fixedly installed on one side of the second spring 13. The ball valve mounting seat 6 is slid into the inner side of the mounting bracket 5. After the ball valve mounting seat 6 is slid in, the first spring 10 can drive the limiting plate 11 to slide. The limiting plate 11 can limit and lock the ball valve mounting seat 6. The second springs 13 on both sides can drive the locking block 14 to slide into the inner side of the slot above the ball valve mounting seat 6, so that the ball valve mounting seat 6 is relatively stable after installation. When disassembling, you only need to pull the limiting plate 11 to release the limitation on the ball valve mounting seat 6. After the limiting plate 11 slides, it can pull the pulling plate 15 to move the locking block 14, which makes it easy for the staff to take out the ball valve mounting seat 6 and the ball valve body 9 for maintenance.

[0025] In this embodiment, a pull plate 15 is fixedly installed on one side of the card block 14, and one side of the pull plate 15 is fixedly installed on the front side of the limiting plate 11.

[0026] In this embodiment, a control block 16 is fixedly installed at the bottom of the ball valve body 9, an auxiliary shaft 17 is rotatably installed at the bottom of the valve seat 2, a force-bearing block 18 is fixedly installed at the top of the auxiliary shaft 17, and a flow diversion baffle 19 is fixedly installed at the bottom of the auxiliary shaft 17. In this embodiment, a control groove is opened at the top of the force-bearing block 18, and the control block 16 fits into the control groove. After the ball valve body 9 is slid into the inner side of the valve seat 2, the sealing ring 20 can make the ball valve mounting seat 6 and the valve seat 2 connect more tightly, so that the sealing effect is better, and the control block 16 above the ball valve body 9 can slide into the inner side of the force-bearing block 18.

[0027] In this embodiment, the diversion pipe 4 is C-shaped, with a rotating groove at the top. The auxiliary shaft 17 is rotatably installed inside the rotating groove, and the diversion baffle 19 is in contact with the inner wall of the diversion pipe 4. In this embodiment, a slot is provided on the rear side of the ball valve mounting seat 6, and the locking block 14 is in contact with the slot. A sealing ring 20 is fixedly installed at the bottom of the ball valve mounting seat 6, and the sealing ring 20 is in contact with the valve seat 2. When the valve needs to be opened, the rotating shaft 7 and the ball valve body 9 can be rotated by the knob 8 below. After the ball valve body 9 is rotated, the auxiliary shaft 17 and the diversion baffle 19 can be rotated by the cooperation of the control block 16 and the force block 18, so that the water flow inside the flow pipe 3 can flow through the ball valve body 9 and the diversion pipe 4. The diversion pipe 4 allows the liquid to be diverted, thereby reducing the liquid water pressure and preventing the water flow from damaging the ball valve body 9, thereby improving the service life of the ball valve body 9.

[0028] The implementation principle of a divertable ball valve in this embodiment is as follows: the ball valve mounting seat 6 is slid into the inner side of the mounting bracket 5. After the ball valve mounting seat 6 is slid in, the first spring 10 can drive the limiting plate 11 to slide, and the limiting plate 11 can limit and lock the ball valve mounting seat 6. The second springs 13 on both sides can drive the locking block 14 to slide into the inner side of the locking groove above the ball valve mounting seat 6, so that the ball valve mounting seat 6 is relatively stable after installation. When disassembling, simply pull the limiting plate 11 to release the limitation on the ball valve mounting seat 6. After the limiting plate 11 slides, it can pull the pulling plate 15 to move the locking block 14, which makes it convenient for the staff to remove the ball valve mounting seat 6 and the ball valve body 9 for maintenance. After the ball valve body 9 is slid into the valve seat 2... The sealing ring 20 allows the ball valve mounting seat 6 and the valve seat 2 to be connected more tightly, resulting in a better sealing effect. The control block 16 on the upper part of the ball valve body 9 can slide into the inside of the force-bearing block 18. When the valve needs to be opened, the rotating shaft 7 and the ball valve body 9 can be rotated by the knob 8 below. After the ball valve body 9 is rotated, the auxiliary shaft 17 and the diversion baffle 19 can be rotated by the cooperation of the control block 16 and the force-bearing block 18. This allows the water flow inside the flow pipe 3 to flow through the ball valve body 9 and the diversion pipe 4. The diversion pipe 4 allows the liquid to be diverted, thereby reducing the liquid water pressure and preventing the water flow from damaging the ball valve body 9, thus improving the service life of the ball valve body 9.
