Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a valve casting that can be quickly connected to a pipeline. Background Technology

[0002] Valve castings are the main structure of valves. Valves are control devices used to control the flow rate of fluid in pipelines after they are connected to them. They are one of the most common pipeline connection devices. Currently, sealing valve castings are used.

[0003] A prior patent (publication number: CN220910582U) discloses a valve casting with an anti-clogging structure, comprising a pipe, a switch valve on the base surface of the pipe, a filter screen on the left side inside the pipe, a collection groove at the bottom of the pipe and to the left of the filter screen, and a collection box at the bottom of the pipe and below the collection groove. Through this valve casting with its anti-clogging structure, impurities in the fluid are filtered through the filter screen during use, and the filtered impurities fall into the collection box. If the filtered impurities are large, an electric telescopic rod can move a rotating rod downwards, thereby driving a cutting blade to chop the larger impurities when the drive motor is running, and then the curities fall into the collection box. This avoids clogging caused by impurity accumulation, making it more convenient to use. The overall device has a simple structure, is easy to operate, and is highly practical.

[0004] However, the above technical solution still has certain defects. In the process of using the above technical solution, when the valve is connected to the pipeline, it is fixed by a flange and then by multiple sets of bolts. This makes it necessary to loosen multiple sets of bolts when disassembling, which makes it impossible to disassemble the valve quickly and conveniently. Therefore, a valve casting that can be quickly connected to the pipeline is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a valve casting that can be quickly connected to a pipeline, so as to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve casting that can quickly connect to a pipeline, comprising a valve body, wherein a set of connecting pipes are respectively connected to both ends of the valve body, and a set of water pipes are respectively connected to the end of each set of connecting pipes, and a connecting mechanism is provided at the connection point of the connecting pipes with the water pipes;

[0007] The connecting mechanism includes a fixing ring, which is sleeved on the outer wall of the connecting pipe. Multiple sets of sliding columns are fixedly connected to the side wall of the fixing ring. Each set of sliding columns is fixedly connected to a set of limiting columns at its end. A pressure ring is slidably sleeved on the outer wall of the multiple sets of limiting columns. The pressure ring abuts against the end of the water pipe. Two sets of limiting rings are sleeved on the outer wall of the multiple sets of limiting columns. One end of the two sets of limiting rings is rotatably connected together, and the other end of the two sets of limiting rings is fixedly connected to a set of buckles.

[0008] As a preferred technical solution for a valve casting that can quickly connect pipes according to this utility model, the connecting pipe has an opening at the contact position with the sliding column, and the limiting column has a groove at the contact position with the limiting ring.

[0009] As a preferred technical solution for a valve casting that can quickly connect pipes according to this utility model, two sets of fixing mechanisms are slidably sleeved at the bottom ends of the two sets of connecting pipes. The fixing mechanism includes a pin, which is slidably sleeved at the bottom end of the connecting pipe.

[0010] As a preferred technical solution of the valve casting for quick connection of pipes according to the present invention, the inner wall of the pin is slidably fitted with a push rod, and the top end of the push rod extends to the outside of the pin.

[0011] As a preferred technical solution of the valve casting for quick connection of pipes according to the present invention, the inner wall of the pin is rotatably connected with two sets of pointed cones near the bottom, and the ends of the two sets of pointed cones extend to the outside of the pin.

[0012] As a preferred technical solution for a valve casting that can quickly connect pipes according to this utility model, each set of pins has a set of connecting rods hinged to its outer wall, and the top ends of the two sets of connecting rods are hinged to the bottom end of the push rod.

[0013] As a preferred technical solution for a valve casting that can quickly connect to a pipeline according to this utility model, a return spring is sleeved on the outer wall of the push rod, the bottom end of the return spring is fixedly connected to the inner wall of the pin, and the top end of the return spring is fixedly connected to the outer wall of the push rod.

[0014] In summary, the present invention has the following main advantages:

[0015] 1. This utility model pushes two sets of limiting rings to separate the buckles on the two sets of limiting rings. At this time, the buckles can be separated from the limiting post, so that the pressure ring can slide out from the outer wall of the limiting post. This allows the valve body to be quickly and conveniently separated from the water pipe when disassembling the valve body. Similarly, it also allows for quick pipe connection during installation, improving the work efficiency when maintaining and replacing the valve body.

[0016] 2. This utility model pushes a push rod to rotate a pointed cone, so that the end of the pointed cone does not contact the inner wall of the mounting hole, allowing the pin to be pulled out from the inner wall of the mounting hole. This allows the valve to be quickly removed from the mounting position and can also be quickly fixed to the mounting hole during valve installation, further improving the work efficiency during valve installation.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] A valve casting that allows for quick pipe connection, such as Figures 1 to 5 As shown, it includes a valve body 1, with a set of connecting pipes 2 connected to both ends of the valve body 1, and a set of water pipes 3 abutting the end of each set of connecting pipes 2. A connecting mechanism 4 is provided at the connection point between the connecting pipes 2 and the water pipes 3.

[0028] The connecting mechanism 4 includes a fixing ring 401, which is sleeved on the outer wall of the connecting pipe 2. Multiple sets of sliding columns 402 are fixedly connected to the side wall of the fixing ring 401. A set of limiting columns 404 are fixedly connected to the end of each set of sliding columns 402. A pressure ring 405 is slidably sleeved on the outer wall of the multiple sets of limiting columns 404. The pressure ring 405 abuts against the end of the water pipe 3. Two sets of limiting rings 406 are sleeved on the outer wall of the multiple sets of limiting columns 404. One end of the two sets of limiting rings 406 is rotatably connected together. A set of buckles 407 is fixedly connected to the other end of the two sets of limiting rings 406. An opening 403 is opened at the contact position with the sliding column 402 in the connecting pipe 2. A groove is opened at the contact position with the limiting ring 406 in the limiting column 404.

[0029] By connecting the water pipe 3 and the connecting pipe 2, and then pushing the fixing ring 401, the fixing ring 401 causes the sliding post 402 to pass through the opening 403. Then, a set of pressure rings 405 are fitted onto the outer wall of the limiting post 404, so that the pressure rings 405 press against the end of the water pipe 3, causing this set of limiting rings 406 to slide into the groove on the outer wall of the pressure ring 405. Then, the other set of limiting rings 406 is flipped, so that the other set of limiting rings 406 also slides into the groove on the outer wall of the limiting post 404, and the buckles 407 on the two sets of limiting rings 406 are engaged. The clips are engaged together, and the clip 407 is made of a flexible material, so that the clip 407 can be separated or engaged when pulled manually. At this time, the pressure ring 405 cannot slide out from the outer wall of the limiting post 404. When it is necessary to separate the water pipe 3 from the connecting pipe 2, it is necessary to pull the two sets of limiting rings 406 to separate the two sets of clips 407, so that the pressure ring 405 will not be blocked by the limiting ring 406. Then, pull the pressure ring 405 so that the pressure ring 405 no longer abuts against the end of the water pipe 3, so that the water pipe 3 and the connecting pipe 2 can be separated quickly.

[0030] Please refer to this carefully. Figure 1 and Figure 5 Two sets of fixing mechanisms 5 are slidably sleeved at the bottom ends of the two sets of connecting pipes 2. The fixing mechanism 5 includes a pin 501, which is slidably sleeved at the bottom end of the connecting pipe 2. A push rod 502 is slidably sleeved on the inner wall of the pin 501. The top end of the push rod 502 extends to the outside of the pin 501. Two sets of pointed cones 503 are rotatably connected to the inner wall of the pin 501 near the bottom end. The ends of the two sets of pointed cones 503 extend to the outside of the pin 501. A set of connecting rods 504 are hinged to the outer wall of each set of pins 501. The top ends of the two sets of connecting rods 504 are hinged to the bottom end of the push rod 502. A return spring 505 is sleeved on the outer wall of the push rod 502. The bottom end of the return spring 505 is fixedly connected to the inner wall of the pin 501, and the top end of the return spring 505 is fixedly connected to the outer wall of the push rod 502.

[0031] By pushing the push rod 502, the push rod 502 pushes the connecting rod 504 downward and compresses the return spring 505, thereby causing the connecting rod 504 to push the cone 503 to flip, so that the end of the cone 503 cannot contact the inner wall of the mounting hole. Then, the pin 501 is inserted into the mounting hole. Then, the push rod 502 is released, causing the return spring 505 to rebound, thereby pushing the push rod 502 to reset. The push rod 502 drives the cone 503 to flip in the opposite direction and reset through the connecting rod 504, so that the end of the cone 503 abuts against the inner wall of the mounting hole, thereby preventing the pin 501 from sliding out of the mounting hole, thus fixing the valve body 1.

[0032] In use, by pushing the two sets of limiting rings 406, the buckles 407 on the two sets of limiting rings 406 are separated. At this time, the buckles 407 can be separated from the limiting post 404, so that the pressure ring 405 can slide out from the outer wall of the limiting post 404. This allows the valve body 1 to be quickly and easily separated from the water pipe 3 when disassembling the valve body 1, improving the work efficiency when maintaining and replacing the valve body 1. The parts not involved in this device are the same as or can be implemented using existing technology.
