Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve body technology, specifically to an impact-resistant valve body. Background Technology
[0002] In industrial fluid control systems and various applications involving fluid transport and regulation, the valve body, as a core component controlling fluid flow and pressure, is crucial for the stable and reliable operation of the entire system. As industrial production moves towards higher parameters, the impact of fluid on the valve body becomes increasingly prominent, severely affecting valve lifespan and system safety.
[0003] Currently, conventional valve bodies have many drawbacks when facing high-speed fluid impacts, pulsating flow impacts, or impacts from fluids containing impurities. On the one hand, the internal flow channel design of valve bodies is mostly a simple straight line or right-angle turn structure. When fluid flows through, it is prone to violent pressure fluctuations and impacts due to sudden changes in flow direction, leading to stress concentration inside the valve body. Under long-term action, components such as the valve body wall and valve plate are prone to cracks, deformation, or even breakage and failure. On the other hand, the valve body's ability to buffer and disperse fluid impacts is insufficient. Fluid directly impacts the valve plate and critical parts of the valve body, accelerating the wear of sealing surfaces and damaging the valve plate. This not only increases the frequency and cost of equipment maintenance but may also cause safety accidents such as leaks, affecting the continuity and stability of production. Utility Model Content

[0006] A spiral-shaped flow channel is formed inside the connecting pipe, and the flow channel is connected to the input end to guide the fluid to flow in a spiral shape;
[0007] A flow divider plate is provided inside the valve body and located at the input end. The flow divider plate has several flow divider holes inside to disperse a single fluid into multiple fluids that are input into the valve body.
[0008] A second inclined plate is integrally formed inside the valve body and on the side near the input end, and a first inclined plate is provided inside the valve body and on the side near the output end. A valve plate is inserted between the second inclined plate and the first inclined plate.
[0009] Furthermore, a screw is provided through the top of the valve body, one end of which is connected to the valve plate for transmission.
[0010] Furthermore, a backflow bend with an angle of less than ninety degrees is formed between the first inclined plate and the inner bottom wall of the valve body.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0016] 1. This anti-impact valve body initially guides and buffers the fluid through a spiral flow channel inside the connecting pipe.

[0022] 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.
[0023] Please see Figure 1-3 The anti-impact valve body in this embodiment aims to solve the problems of component damage and sealing surface wear that are easily caused by conventional valve bodies when facing high-speed fluid impact, pulsating flow impact or fluid impact containing impurities.
[0024] Specifically, the anti-impact valve body includes a valve body 1, with a connecting pipe 2 connected to the left end of the valve body 1. One end of the valve body 1 connected to the connecting pipe 2 is the input end, and the other end is the output end. A spiral-shaped flow guide channel 3 is provided inside the connecting pipe 2. This flow guide channel 3 is connected to the input end and can guide the fluid to flow in a spiral shape.
[0025] In actual setup, before entering the valve body 1, the fluid is guided by the spiral flow channel 3 to flow in a spiral shape. The spiral flow reduces the direct impact force of the fluid and achieves a preliminary buffering effect.
[0026] A flow divider 4 is provided inside the valve body 1 at the inlet end. The flow divider 4 has several flow divider holes, which can disperse a single fluid into multiple flow streams that enter the valve body 1. A retaining ring 10 is installed inside the valve body 1 on the right side of the flow divider 4. The retaining ring 10 abuts against the right side of the flow divider 4, which serves to fix the flow divider 4.
[0027] In actual use, the flow divider 4 is located inside the valve body 1 at the inlet end, opposite to the outlet of the connecting pipe 2. When the fluid guided by the flow guide channel 3 enters the inlet end, it will flow to the flow divider 4. Several flow divider holes on the flow divider 4 will disperse a single fluid into multiple streams, thereby dispersing the impact force of the fluid and preventing a single stream of fluid from concentrating and impacting the internal components of the valve body 1, thus reducing the possibility of damage to the components due to excessive local stress.
[0028] In addition, the retaining ring 10 is installed inside the valve body 1 and located on the right side of the flow divider 4, and abuts against the right side of the flow divider 4 to prevent the flow divider 4 from shifting or shaking under the impact of the fluid, ensuring that the flow divider 4 can stably perform the flow divider function and ensuring the stability of the entire valve body structure.
[0029] A second inclined plate 5 is integrally formed inside the valve body 1, near the input end, and a first inclined plate 6 is formed near the output end. A valve plate 7 is inserted between the second inclined plate 5 and the first inclined plate 6. A screw 8 is driven through the top of the valve body 1, one end of which is connected to the valve plate 7. By rotating the screw 8, the valve plate 7 can be moved up and down, thereby controlling the flow and the amount of fluid.
[0030] A backflow bend 9 with an angle of less than 90 degrees is formed between the first inclined plate 6 and the inner bottom wall of the valve body 1, and the backflow bend 9 faces the input end.
[0031] In practical application, when the fluid flows through the first inclined plate 6, the fluid will impact the first inclined plate 6. The return bend 9 guides this part of the fluid to form a return flow. The return fluid can interact with the subsequent inflowing fluid, reduce the impact force of the subsequent fluid, play a buffering role, and at the same time reduce the direct impact of the fluid on the first inclined plate 6 and the bottom wall of the valve body 1.
[0032] In addition, the valve body 1, connecting pipe 2 and retaining ring 10 are all made of stainless steel. Stainless steel has good corrosion resistance and strength, which can further improve the valve body's impact resistance and service life.
[0033] In actual installation, the valve body 1, connecting pipe 2, and retaining ring 10 are all made of stainless steel. Stainless steel has high strength and corrosion resistance. The use of this material for all components and their interconnection allows the entire valve body to withstand greater fluid impact forces and is not easily corroded by fluids, thus extending the service life of the valve body and ensuring stable operation of the valve body under harsh working conditions.
[0034] The working principle of the above embodiments is as follows:
[0035] 1. When the fluid enters from the connecting pipe 2, it first flows through the spiral guide channel 3 inside the connecting pipe 2. Under the action of the guide channel 3, the fluid flows spirally towards the input end of the valve body 1. The spirally flowing fluid enters the input end of the valve body 1 and flows towards the diverter plate 4. The diverter holes on the diverter plate 4 disperse the single fluid into multiple small fluid flows. The impact force of the dispersed fluid is greatly reduced, avoiding concentrated impact on the internal components of the valve body 1.
[0036] 2. When the fluid flows through the first inclined plate 6, some of the fluid may impact the first inclined plate 6. The backflow bend 9 formed between the first inclined plate 6 and the inner bottom wall of the valve body 1 faces the input end and can guide this impacting fluid to form a backflow. The backflowing fluid interacts with the subsequent inflowing fluid, further reducing the impact force of the fluid and reducing damage to the internal components of the valve body.
