Description

Technical Field

[0001] This utility model belongs to the field of valve equipment, and specifically relates to a high-flow pipe-type check valve. Background Technology

[0002] A pipe-type check valve is a valve used to control the unidirectional flow of fluid. However, pipe-type check valves have some drawbacks in practical applications. Traditional pipe-type check valves experience high flow resistance at high flow rates, restricting smooth fluid flow. This is because the valve's internal passage is relatively narrow; as the fluid flow rate increases, the pressure drop within the passage increases, thus affecting the valve's flow capacity. A conventional solution is to adjust the spring force to control the valve core opening degree to adapt to different flow requirements. However, this method increases the valve opening pressure, potentially preventing proper opening at low flow rates and increasing system energy consumption. Furthermore, the spring force adjustment range is limited, making it difficult to accurately adapt to complex flow changes. Therefore, a new structure is needed to address these technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-flow tubular check valve to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a high-flow-rate pipe-type one-way valve, comprising: valve assembly one, valve assembly two, a feed component, and a discharge component. The upper surface of valve assembly one is equipped with valve assembly two for active closure via a connecting flange one. The outer surface of valve assembly one is equipped with a feed component for connection to an inlet device. The lower surface of valve assembly one is equipped with a discharge component for outflow via a connecting flange two. Valve assembly one includes a valve body component for preventing backflow of the inlet fluid, and the valve body component is installed inside valve body one.

[0005] In a preferred embodiment, the upper and lower surfaces of the valve body are designed to be open, and a valve assembly two is installed at the opening on the upper surface of the valve body two through a connecting flange two. The valve assembly two includes the valve body two.

[0006] In a preferred embodiment, a second valve body is mounted on the upper surface of the first valve body via a connecting flange, which is used to actively close the opening on the upper surface of the first valve body. The feeding component includes an inlet pipe and an inlet pipe.

[0007] In a preferred embodiment, an inlet pipe is installed on the outer surface of the valve body, and the end of the inlet pipe away from the valve body is connected to the outer surface of the inlet pipe. The inlet pipe and the inlet pipe form a T-shaped structure and are connected to each other.

[0008] In a preferred embodiment, the two ends of the inlet pipe 2 are designed to be open, and the inlet pipe 1 and the inlet pipe 2 are provided with a gradually expanding inlet flow channel, so that the fluid can smoothly enter the valve body 1 and reduce the eddies and pressure loss at the inlet of the inlet pipe 2.

[0009] In a preferred embodiment, a second connecting flange is installed at the opening on the lower surface of the valve body, and the discharge component includes an outlet pipe. The outlet pipe is installed at the opening on the lower surface of the valve body through the second connecting flange, and an outlet is provided at the end of the outlet pipe away from the first connecting flange.

[0010] In a preferred embodiment, the outlet is provided with a gradually narrowing outlet channel, which allows the fluid to quickly recover pressure after flowing out of the outlet pipe, thereby improving the valve's flow coefficient. In use, the feed pipes 1 and 2 are provided with gradually expanding inlet channels, and the outlet pipe is provided with a gradually narrowing outlet channel. This allows the fluid to enter smoothly, reduces resistance, and improves the flow coefficient, thereby effectively improving the working flow efficiency of the check valve.

[0011] In a preferred embodiment, the valve body includes a fixed frame, a valve plate, a movable rod, and a compression spring. Two fixed frames are symmetrically installed on the inner wall of the valve body, and a movable rod is movably installed between the two fixed frames.

[0012] A valve plate is integrally formed on the outer surface of the movable rod. The valve plate is snapped into and abuts against the inner wall of the valve body. A compression spring is connected between the upper surface of the lower fixed frame and the lower surface of the valve plate through the movable rod. The compression spring has a conical structure. During use, the valve plate in the valve body can open smoothly in the normal fluid flow direction to ensure the smooth passage of high-flow fluid. When the fluid shows a reverse flow tendency, the valve plate will close quickly under the action of fluid pressure and compression spring, effectively preventing fluid backflow and ensuring the one-way conduction function of the check valve, thus maintaining the normal operation of the system.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by setting up a feeding component and a discharging component, the feeding component includes an inlet pipe one and an inlet pipe two, and the discharging component includes an outlet pipe. The inlet pipe one and the inlet pipe two are provided with a gradually expanding inlet channel, and the outlet is provided with a gradually contracting outlet channel. In use, the gradually expanding inlet channel of the inlet pipe one and the inlet pipe two of the feeding component and the gradually contracting outlet channel of the outlet pipe of the discharging component enable the fluid to enter smoothly, reduce resistance, and increase the flow coefficient, thereby effectively improving the working flow efficiency of the check valve.

[0014] By setting up valve assembly one, which includes a valve body component for preventing backflow of the incoming fluid, the valve body component is installed inside the valve body one. The valve body component includes a fixed frame, a valve plate, a movable rod, and a compression spring. In use, the valve plate in the valve body component can open smoothly in the normal fluid flow direction to ensure the smooth passage of high-flow-rate fluid. When the fluid shows a backflow tendency, the valve plate will close quickly under the action of fluid pressure and compression spring, effectively preventing the fluid backflow, ensuring the one-way conduction function of the check valve, maintaining the normal operation of the system, and preventing problems such as equipment damage and efficiency reduction that may be caused by backflow.

[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 Figures 1 to 3This utility model provides a technical solution: a high-flow pipe-type one-way valve, comprising: valve assembly one, valve assembly two, a feed component, and a discharge component. The upper surface of valve assembly one is equipped with valve assembly two for active closure via a connecting flange one 200. The outer surface of valve assembly one is equipped with a feed component for connection to the inlet device. The lower surface of valve assembly one is equipped with a discharge component for outflow via a connecting flange two 300. Valve assembly one includes a valve body component for preventing backflow of the inlet fluid, and the valve body component is installed inside valve body one 100.

[0024] Please see Figures 1 to 3 As the first embodiment of this utility model: the upper and lower surfaces of the valve body 100 are designed to be open, and the valve assembly 2 is installed at the opening of the upper surface of the valve body 100 through the connecting flange 200. The valve assembly 2 includes the valve body 210.

[0025] A valve body 210 is installed on the upper surface of valve body 100 via a connecting flange 200, which is used to actively close the opening on the upper surface of valve body 100. The feed components include: inlet pipe 110 and inlet pipe 220.

[0026] An inlet pipe 110 is installed on the outer surface of the valve body 100. The end of the inlet pipe 110 away from the valve body 100 is connected to the outer surface of the inlet pipe 2 120. The inlet pipe 110 and the inlet pipe 2 120 form a T-shaped structure and are connected to each other.

[0027] The two ends of the inlet pipe 120 are designed to be open. The inlet pipe 110 and the inlet pipe 120 are provided with a gradually expanding inlet flow channel to allow the fluid to enter the valve body 100 smoothly and reduce the eddy currents and pressure loss at the inlet of the inlet pipe 120.

[0028] A connecting flange 300 is installed at the opening on the lower surface of the valve body 100. The discharge component includes an outlet pipe 310. An outlet pipe 310 is installed at the opening on the lower surface of the valve body 100 through the connecting flange 300. An outlet is provided at the end of the outlet pipe 310 away from the connecting flange 200.

[0029] The outlet is equipped with a tapered outlet channel to allow the fluid to quickly regain pressure after flowing out of the outlet pipe 310, thereby improving the valve's flow coefficient.

[0030] In use, the user first connects the entire device to the inlet device via the feeding component, and connects the outlet of the discharge component to another receiving device. After connection, the user can open the valve body 210 on the upper surface of valve body 100, creating a passage. When the inlet device enters the valve body 100 through inlet pipe 2120 and inlet pipe 110, it will first pass through valve body 100 and then exit through outlet pipe 310. Because inlet pipe 110 and inlet pipe 2120 are equipped with gradually expanding inlet channels, the flow... The fluid can smoothly enter the valve body 100, reducing eddies and pressure losses at the inlet of the inlet pipe 120. When the fluid is discharged from the outlet pipe 310, the outlet of the outlet pipe 310 is equipped with a gradually narrowing outlet channel, which allows the fluid to quickly recover pressure after flowing out of the outlet pipe 310, thereby improving the valve's flow coefficient. Because the feed pipe 110 and the inlet pipe 120 of the feed element are equipped with gradually expanding inlet channels, and the outlet pipe 310 of the discharge element is equipped with a gradually narrowing outlet flow, the fluid can enter smoothly, reduce resistance, and improve the flow coefficient, thereby effectively improving the working flow efficiency of the check valve.

[0031] Please see Figures 1 to 3 As a second embodiment of the present utility model: the valve body includes a fixed frame 130, a valve plate 150, a movable rod 140 and a compression spring 160. Two fixed frames 130 are symmetrically installed on the inner wall of the valve body 100, and a movable rod 140 is movably installed between the two fixed frames 130.

[0032] A valve plate 150 is integrally formed on the outer surface of the movable rod 140. The valve plate 150 is snapped into the inner wall of the valve body 100. A compression spring 160 is fitted between the upper surface of the lower fixing bracket 130 and the lower surface of the valve plate 150 through the movable rod 140. The compression spring 160 has a conical structure.

[0033] In use, when fluid enters the valve body 100 through the feed element, the water flow impacts the valve plate 150, causing the valve plate 150 to move the movable rod 140 along the two fixed brackets 130. As the valve plate 150 moves, the compression spring 160 connected to its lower surface is also compressed. At this time, the contact point between the valve plate 150 and the valve body 100 is opened by the water flow, allowing water to pass through. When the water flows back, the returning water impacts the valve plate 150 and is then compressed again by the compression spring. Spring 160 re-engages valve plate 150 with valve body 100, thereby preventing backflow of water. During use, valve plate 150 in the valve body can open smoothly in the normal fluid flow direction, ensuring the smooth passage of high-flow fluid. When the fluid shows a reverse flow tendency, valve plate 150 will quickly close under the action of fluid pressure and compression spring 160, effectively preventing backflow of fluid, ensuring the one-way conduction function of the check valve, maintaining the normal operation of the system, and preventing equipment damage and efficiency reduction caused by backflow.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
