Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of check valves, in particular to an adjustable track ball check valve. Background Art
[0002] A check valve is a valve whose opening and closing part is a circular disc and which relies on its own weight and medium pressure to produce movement to block the backflow of the medium. It is an automatic valve. The medium flows in from the inlet end and flows out from the outlet end. When the inlet pressure is greater than the sum of the weight of the disc and its flow resistance, the valve is opened. Conversely, the valve is closed when the medium flows back. The check valve is often installed at the outlet of the water pump in the water supply and drainage pipeline. Its purpose is to prevent water from flowing back when the water pump stops running.
[0003] However, the check valve currently used has only one ball check valve inside, which is mainly engaged by the flow direction of water flow, and is prone to loosening during the engagement process, causing backflow.
[0004] In view of this, research and improvement are carried out on the existing problems, and an adjustable track ball check valve is provided, which has a reasonable structural design, is easy to use, has good backflow prevention effect, and can filter dirt, reduces manpower and material resources, and greatly improves work efficiency. The purpose is to solve the problem and improve the practical value through this technology. Utility Model Content

[0027] Reference Figure 1-4, the utility model provides an embodiment: an adjustable track ball check valve, including a check valve body 1, a fixed plate 2 is fixedly connected to one side of the check valve body 1, and a mounting plate 3 is movably connected to one side of the fixing plate 2, which is convenient for the subsequent installation of the mounting frame 11, and a fixing hole 4 is arranged on the outer wall of the mounting plate 3, and a filter screen 5 is arranged between the fixing plate 2 and the mounting plate 3 to prevent the outer diameter dirt from entering the interior, and an adjusting seat 6 is fixedly connected to the top of the check valve body 1, and a top cover 7 is movably connected to the top of the adjusting seat 6, which is detachable and convenient for subsequent maintenance, and the inner wall of the top cover 7 is provided with Threaded rod 8, a hand wheel 9 is fixedly connected to the top of the threaded rod 8, an external thread 10 is provided on the outer wall of the adjusting seat 6, a mounting frame 11 is fixedly connected to the outer wall of the filter screen 5, a push plate 12 is fixedly connected to the bottom of the threaded rod 8, a spherical check valve 13 is fixedly connected to the bottom of the push plate 12, and cooperates with the valve port 14 to prevent subsequent backflow, a valve port 14 is provided inside the check valve body 1, a placement cavity 15 is provided on one side of the fixing plate 2, a screw 16 is movably connected to the inner wall of the fixing hole 4, and a nut 17 is movably connected to one side of the screw 16, to fix the mounting plate 3 and the fixing plate 2.
[0028] Specifically, the outer walls of the fixing plate 2 and the mounting plate 3 are penetrated with fixing holes 4 , and the fixing holes 4 on the outer wall of the fixing plate 2 are consistent in size and position with the fixing holes 4 on the outer wall of the mounting plate 3 , which facilitates the subsequent installation of the fixing plate 2 and the mounting plate 3 .
[0029] Specifically, the screws 16 and the nuts 17 form a fixing structure, and the number of the fixing structures is four. The fixing structure cooperates with the fixing holes 4 to quickly fix, and at the same time facilitates the subsequent disassembly and replacement of the internal filter 5.
[0030] Specifically, a valve port 14 is provided at the bottom of the ball check valve 13 , and the two sides of the valve port 14 are arc-shaped. The ball check valve 13 is movably connected to the valve port 14 , so that the ball check valve 13 and the valve port 14 fit better and the backflow prevention effect is better.
[0031] Specifically, the installation frame 11 and the filter screen 5 form a filtering structure, and the number of filtering structures is two groups.

When the internal flow is too large and needs to be adjusted, the user turns the handwheel 9 to move the threaded rod 8 downward, and the ball check valve 13 and the valve port 14 are close to each other to achieve the effect of limiting the flow. When backflow prevention is required, just continue to turn the handwheel 9 to make the ball check valve 13 fit the valve port 14.
