[0002] Check valves are widely used in various pipeline systems. Their main function is to prevent the backflow of media. They rely on the change of the flow pressure of the media itself to automatically open and close, thereby preventing the backflow of media.
[0003] During the use of traditional check valves, the valve flap is impacted by high-pressure fluid, which easily causes damage to the valve flap, resulting in a decline in sealing performance and even leakage problems. At the same time, due to the lack of an effective buffering mechanism, the vibration and noise generated during the rapid opening and closing of the valve are also relatively large, affecting the operating stability and service life of the system.

By arranging a chute, a buffer assembly, a slider and a flow-blocking block in the valve barrel, when the fluid passes through, the slider slides in the chute, and at the same time drives the buffer assembly to work, providing a buffering force for the valve flap, reducing the impact it receives, and realizing effective protection and buffering and shock absorption for the valve flap.

[0006] The buffer assembly is arranged in a buffer groove on the inner wall of the chute. A sliding rod is slidably connected to the inner wall of the buffer groove. One end of the sliding rod located on the inner wall of the buffer groove is fixedly connected with a buffer spring, and the end of the sliding rod away from the buffer spring is fixedly connected with one side of the slider.

[0021] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.
[0022] Referring to Figures 1-4, in an embodiment of the utility model, an arrow-shaped check valve with a spring protection structure includes: a valve barrel 1, connecting flanges 2 are fixedly connected to both ends of the valve barrel 1, a sliding groove 3 is arranged on the inner wall of the valve barrel 1, a buffer assembly 4 is arranged on the inner wall of the sliding groove 3, a slider 5 is slidably connected to the inner wall of the sliding groove 3, a receiving frame 6 is fixedly connected to one side of the slider 5, a reinforcing frame 7 is fixedly connected to the inner wall of the receiving frame 6, and a flow blocking block 8 is fixedly connected to one side of the receiving frame 6;
[0023] The buffer assembly 4 is arranged in a buffer groove 401 on the inner wall of the sliding groove 3. A sliding rod 402 is slidably connected to the inner wall of the buffer groove 401. One end of the sliding rod 402 located on the inner wall of the buffer groove 401 is fixedly connected to a buffer spring 403. The end of the sliding rod 402 far from the buffer spring 403 is fixedly connected to one side of the slider 5. The impact force and pressure of the water flow are reduced by the buffer assembly 4.
[0024] There are two reinforcing frames 7, and the two reinforcing frames 7 are arranged in a cross shape. The stability of the receiving frame 6 is improved by the cross-shaped reinforcing frames 7.
[0025] There are four sliding grooves 3, and the four sliding grooves 3 are symmetrically distributed around the central axis of the valve barrel 1.
[0026] A hydraulic rod 301 is fixedly connected to the inner wall of the sliding groove 3. One end of the hydraulic rod 301 is fixedly connected to one side of the slider 5. The pressure of the water flow is further buffered by the hydraulic rod 301.
[0027] The surface of the flow blocking block 8 is arc-shaped. It can slow down the impact force of the water flow and prevent the flow blocking block 8 from deforming.
[0028] Working principle: When in use, when the fluid flows through the valve barrel 1, the pressure of the fluid pushes the flow blocking block 8 to open, so that the fluid can flow smoothly. At the same time, the slider 5 slides in the sliding groove 3, and the sliding of the slider 5 drives the receiving frame 6 and the reinforcing frame 7 to move. At this time, the sliding rod 402 slides inside the buffer groove 401, and at the same time, the buffer spring 403 provides the necessary buffer force to reduce the damage caused by the fluid impact. When the fluid stops flowing, the flow blocking block 8 closes under the action of the buffer spring 403 and the hydraulic rod 301. At this time, the slider 5 slides inside the sliding groove 3 and drives the receiving frame 6 and the reinforcing frame 7 to reset.
[0029] The above has described the embodiments of the utility model in detail with reference to the drawings. However, the utility model is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the purpose of the utility model.
