Description

Technical Field

[0001] This invention relates to the field of valve technology, specifically to a corrosion-resistant valve casting with pressure monitoring. Background Technology

[0002] Valve castings are metal shaped objects created using casting processes. Molten molten metal is poured into a pre-prepared mold through methods such as pouring, injection, suction, or other casting techniques. After cooling, subsequent processing such as grinding is performed to obtain an object with a specific shape, size, and performance. Ball valves are a commonly used type of valve. Existing ball valves use a valve stem to drive a ball to rotate around its axis, thereby regulating and controlling fluid flow. However, after the ball valve is closed, some fluid usually remains inside the ball. This prolonged fluid retention can easily corrode the ball, reducing the valve's lifespan. Furthermore, the fluid can easily deteriorate inside the ball valve, and when it is reopened, it mixes with other fluids, potentially affecting the fluid quality.

[0003] Therefore, the present invention provides a corrosion-resistant valve casting with pressure monitoring. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a corrosion-resistant valve casting with pressure monitoring to solve the problems mentioned in the background art. The present invention can recover the fluid in the connection port after the valve is closed, thereby preventing the fluid from remaining in the connection port for a long time and deteriorating, and preventing corrosion of the inner wall of the connection port; it can prevent the ball core from working in a high-temperature environment for a long time, thus accelerating the corrosion rate; it can prevent the outer surface of the ball core from being corroded; and it can also isolate the ball core from the fluid after the valve is closed, thereby reducing the contact time with the fluid.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a corrosion-resistant valve casting with pressure monitoring, comprising a valve body, an inlet at one end of the valve body, an outlet at the other end of the valve body, connecting structures at both ends of the valve body, a ball core rotatably fitted inside the valve body, a connecting port inside the ball core, a rotating seat fixed inside the valve body, the rotating seat corresponding to the ball core, a cooling structure installed inside the rotating seat, a sealing structure and a wiping structure installed on the rotating seat, both of the sealing structure and the wiping structure corresponding to the ball core, a recovery box installed on the valve body, the recovery box corresponding to the connecting port, and a valve stem rotatably fitted on the valve body, the valve stem being fixedly connected to the ball core.

[0006] Furthermore, the connection structure includes a flange, and the flange and valve body are an integral structure.

[0007] Furthermore, slots are provided at both ends of the valve body, and liquid pressure detectors are installed at both ends of the valve body, with the liquid pressure detectors corresponding to the slots.

[0008] Furthermore, a sealing block is fixed on the liquid pressure detector, and the sealing block is located in the slot.

[0009] Furthermore, the recycling bin is fixed to the lower side of the valve body, and the recycling bin is connected to the valve body.

[0010] Furthermore, the bottom of the recycling bin has a recycling port, which is filled with a plug.

[0011] Furthermore, the rotating seat is rotatably connected to the ball core, and the cooling structure includes a cavity opened in the rotating seat, the cavity being filled with coolant.

[0012] Furthermore, the sealing structure includes two sealing rings, which are fixedly connected to the rotating seat, and the two sealing rings are located on both sides of the ball core.

[0013] Furthermore, the wiping structure includes a wiping ring located on the periphery of the ball core, and the wiping ring is fixedly connected to the rotating seat.

[0014] Furthermore, a waterproof paper is fixed to the side of the rotating seat near the water inlet.

[0015] The beneficial effects of the present invention: The present invention provides a corrosion-resistant valve casting with pressure monitoring, comprising a valve body; a recovery tank; a communication port; a rotating seat; a cooling structure; a ball core; a sealing structure; a wiping structure; and waterproof paper.

[0016] Installing a recovery tank on the valve body allows for the recovery of fluid from the connection port after the valve is closed, preventing the fluid from remaining in the connection port for an extended period and causing deterioration, as well as preventing corrosion of the inner wall of the connection port. Installing a cooling structure inside the rotating seat cools the ball core, preventing it from operating in a hot environment for extended periods and accelerating corrosion. Installing a sealing and wiping structure on the rotating seat protects the outer surface of the ball core from corrosion. Installing waterproof paper on the rotating seat isolates the ball core from the fluid after the valve is closed, thus reducing the contact time with the fluid. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] Please see Figures 1 to 8 This invention provides a technical solution: a corrosion-resistant valve casting with pressure monitoring, comprising a valve body 1, an inlet 16 at one end of the valve body 1, an outlet 17 at the other end of the valve body 1, connecting structures at both ends of the valve body 1, a ball core 2 rotatably fitted inside the valve body 1, a connecting port 3 inside the ball core 2, a rotating seat 9 fixed inside the valve body 1, the rotating seat 9 corresponding to the ball core 2, a cooling structure inside the rotating seat 9, a sealing structure and a wiping structure mounted on the rotating seat 9, both of which correspond to the ball core 2, a recovery box 4 mounted on the valve body 1, the recovery box 4 corresponding to the connecting port 3, and a valve stem 8 rotatably fitted on the valve body 1, the valve stem 8 being fixedly connected to the ball core 2.

[0028] In this embodiment, the connection structure includes a flange 18, which is an integral part of the valve body 1. Pipes can be connected through the flange 18, thereby controlling the fluid through the valve.

[0029] Both ends of the valve body 1 are provided with slots 6, and both ends of the valve body 1 are equipped with liquid pressure detectors 5. The liquid pressure detectors 5 correspond to the slots 6, and a sealing block 7 is fixed on the liquid pressure detectors 5. The sealing block 7 is located in the slots 6.

[0030] Specifically, the liquid pressure detector 5 is inserted into the slot 6, causing the sealing block 7 to seal the slot 6. This allows the liquid pressure detector 5 to detect the fluid pressure, and it can also detect leaks at the flange 18 connection and valves based on pressure changes.

[0031] The recycling box 4 is fixed to the lower side of the valve body 1 and is connected to the valve body 1. The bottom of the recycling box 4 has a recycling port 14 and a plug 15 is installed in the recycling port 14.

[0032] Specifically, when the valve is closed, the connecting port 3 is connected to the recycling box 4. Since the recycling box 4 is located at the bottom of the device, the fluid can flow into the recycling box 4 naturally under the action of gravity, which can prevent the fluid from remaining in the ball core 2 for a long time. Then, the fluid in the recycling box 4 can be cleaned through the recycling port 14.

[0033] The rotating seat 9 is rotatably connected to the ball core 2. The cooling structure includes a cavity 12 opened in the rotating seat 9, the cavity 12 is filled with coolant, and the cavity 12 is connected to the outside.

[0034] Specifically, for some hotter fluids, a coolant pipe can be inserted into the cavity 12, and then coolant can be introduced to cool the ball core 2, preventing the ball core 2 from corroding faster due to excessive temperature.

[0035] The sealing structure includes two sealing rings 10, which are fixedly connected to the rotating seat 9. The two sealing rings 10 are located on both sides of the ball core 2. The wiping structure includes a wiping ring 11, which is located on the periphery of the ball core 2 and is fixedly connected to the rotating seat 9.

[0036] Specifically, the sealing ring 10 can be used to seal and prevent leakage, and the wiping ring 11 can be used to wipe the rotating ball core 2, thereby preventing fluid residue on the surface of the ball core 2 and preventing fluid from corroding the surface of the ball core 2.

[0037] Waterproof paper 13 is fixed on the side of the rotating seat 9 near the water inlet 16.

[0038] Specifically, when the valve is opened, the water flows through the waterproof paper 13 into the connecting port 3. The waterproof paper 13 is squeezed against the inner wall of the connecting port 3 by the pressure of the fluid. When the valve is closed, the waterproof paper 13 is squeezed against the ball core 2 by the pressure of the fluid, thus sticking to the surface of the ball core 2 and reducing the contact area between the ball core 2 and the fluid.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
