Description

Technical Field

[0001] This application relates to the field of valve body technology, and in particular to a silent, flow-stopping, buffer valve body casting. Background Technology

[0002] Castings are objects made by casting. They usually refer to parts or components obtained by melting metal, pouring it into the cavity of a mold, and allowing the metal to cool and solidify. The valve body is a key component of a valve, providing a space for the installation and operation of internal valve elements such as valve discs, valve stems, and valve seats. The valve body guides the fluid medium, defining the direction of fluid flow and enabling the fluid to flow within the valve along the designed path.

[0003] Currently, a Chinese utility model patent application with publication number CN 221443464U, published on July 30, 2024, provides a high-pressure valve body casting, including a valve body. The valve body has a connecting channel at its inlet end, which is connected to a valve seat located at the inlet end. The valve seat and the connecting channel have a connecting groove, and a sliding plate is provided in the connecting groove. A sealing ring is provided on one side of the sliding plate, and the other side of the sealing ring is located outside the connecting groove. When the valve is closed, under high pressure, gas enters through the connecting channel and pushes the sliding plate. This causes the sealing ring to adhere tightly to the valve side wall under pressure, increasing its sealing performance and preventing easy leakage.

[0004] In the relevant technology, high-pressure valve body castings generate noise during operation due to the impact of water flow, which is transmitted into the surrounding environment and interferes with the work and life of people in the vicinity. It is necessary to add a buffer structure to reduce the impact of water flow, but this may cause backflow. The backflowing fluid may cause some of the medium that has been delivered to the target location to flow back, resulting in energy waste and increased production costs.

[0005] Therefore, it is necessary to provide a silent, flow-stopping, buffer valve body casting to solve the above problems. Utility Model Content

[0006] This application provides a noise-reducing and flow-stopping buffer valve body casting to improve the technical problems existing in the related art, such as noise generated by the impact of water flow during the operation of the valve body and the possible backflow phenomenon, which leads to energy waste and increased production costs.

[0007] This application provides a silent, flow-stopping buffer valve body casting, including:

[0008] Valve body housing;

[0009] The valve disc seat, located inside the valve body housing, is used to change the flow rate and direction of the medium, thereby reducing noise.

[0010] A water inlet pipe is installed on the valve body housing and communicates with the valve body housing;

[0011] The water outlet pipe is installed on the outer shell of the valve body and communicates with the cavity formed by the inner wall of the valve seat;

[0012] A check valve buffer is installed on the valve seat to buffer the water flow in the inlet pipe and prevent the water from flowing back.

[0013] The technical solutions described above in this application embodiment have at least the following technical effects: When the user controls the water flow using the valve body, the water first enters the gap between the valve body shell and the valve seat through the inlet pipe. The check valve buffer buffers the water flow in the inlet pipe and prevents the water flow from flowing back. At the same time, the valve seat changes the medium flow rate and direction, reducing the impact of the medium on the valve body and the pipeline, thereby reducing noise. The water flows through the upper end of the valve seat into the valve seat and then flows out of the valve body through the outlet pipe.

[0014] The noise-reducing and flow-stopping buffer valve body casting provided in this application embodiment can buffer the impact force of water flow when water enters the valve body through the valve disc seat and check buffer, reduce the possibility of water hammer phenomenon, protect the pipeline system and equipment from water hammer impact damage, and extend the service life of the equipment. The valve disc seat can change the flow rate of the medium, avoid high-speed water flow directly impacting the pipe wall and internal valve components, reduce vibration and noise caused by excessive flow rate, and at the same time reduce scouring and wear on pipelines and equipment.

[0015] In some embodiments, the check buffer includes:

[0016] An abutment plate is disposed on the valve seat;

[0017] The guide post has one end set on the abutment plate and the other end extending into the water inlet pipe;

[0020] In some embodiments, the check buffer plate is provided with a ring array of reinforcing ribs, which can increase the rigidity of the check buffer plate and reduce its vibration amplitude under fluid impact, thereby reducing the noise caused by vibration.

[0022] In some embodiments, both the inlet pipe and the outlet pipe are provided with T-shaped flow buffer rings arranged in an array.

[0023] In some embodiments, both the inlet pipe and the outlet pipe are equipped with flanges to facilitate disassembly and installation with adjacent equipment.

[0030] In the relevant technology, high-pressure valve body castings generate noise during operation due to the impact of water flow, which is transmitted into the surrounding environment and interferes with the work and life of people in the vicinity. It is necessary to add a buffer structure to reduce the impact of water flow, but this may cause backflow. The backflowing fluid may cause some of the medium that has been delivered to the target location to flow back, resulting in energy waste and increased production costs.

[0031] Based on this, in order to improve the technical problems existing in the related technology, such as the noise generated by the impact of water flow during the operation of the valve body, and the possible backflow phenomenon, which leads to energy waste and increased production costs, the embodiments of this application provide the following solutions.

[0032] Please refer to the following: Figures 1 to 3This application provides a noise-reducing and flow-stopping buffer valve body casting, which includes a valve body shell 1, a valve disc seat 13, an inlet pipe 11, an outlet pipe 12, and a check buffer 2. The valve body shell 1 is used to support the parts; the valve disc seat 13 is disposed inside the valve body shell 1 and is used to change the flow rate and direction of the medium, thereby reducing noise; the inlet pipe 11 is disposed on the valve body shell 1 and communicates with the valve body shell 1; the outlet pipe 12 is disposed on the valve body shell 1 and communicates with the cavity formed by the inner wall of the valve disc seat 13; the check buffer 2 is disposed on the valve disc seat 13 and is used to buffer the water flow in the inlet pipe 11 while preventing the water flow from flowing back.

[0033] The noise-reducing and flow-stopping buffer valve body casting provided in this application embodiment allows the user to control water flow through the valve body. First, water flows through the inlet pipe 11 into the gap between the valve body shell 1 and the valve seat 13. The check valve 2 buffers the water flow through the inlet pipe 11 while preventing backflow. Simultaneously, the valve seat 13 changes the medium's velocity and direction, reducing the impact of the medium on the valve body and pipeline, thereby reducing noise. The water flows through the upper end of the valve seat 13 into its interior and then out of the valve body through the outlet pipe 12. Thus, the valve seat 13 and the check valve 2 buffer the impact of the water flow when it enters the valve body, reducing the possibility of water hammer and protecting the pipeline system and equipment from water hammer damage, extending equipment lifespan. The valve seat 13 can change the medium's velocity, preventing high-speed water flow from directly impacting the pipe wall and internal valve components, reducing vibration and noise caused by excessive flow velocity, and simultaneously reducing scouring and wear on the pipeline and equipment.

[0034] In some embodiments, the check buffer 2 includes: an abutment plate 21 disposed on the valve seat 13; a guide post 23, one end of which is disposed on the abutment plate 21 and the other end of which extends into the water inlet pipe 11; a check buffer plate 24, which is slidably and sealingly disposed on the guide post 23; and a telescopic spring 22 sleeved on the guide post 23, one end of which abuts against the abutment plate 21 and the other end of which abuts against the check buffer plate 24.

[0035] With this configuration, when the user controls the water flow using the valve body, the water flow comes into contact with the check buffer plate 24, initially slowing down the water flow. The water flow compresses the telescopic spring 22, causing the check buffer plate 24 to be compressed outside the inlet pipe 11. While providing initial buffering for the water flow in the inlet pipe 11, it also prevents the water flow from flowing back. Subsequently, the water flow enters the gap between the valve body shell 1 and the valve seat 13 through the inlet pipe 11. At the same time, the valve seat 13 changes the medium flow rate and direction, reducing the impact of the medium on the valve body and the pipeline, thereby reducing noise. The water flow enters the valve seat 13 through the upper end of the valve seat 13 and then flows out of the valve body from the outlet pipe 12. Thus, when the water flow velocity and direction are changed by the valve seat 13, the impact force of the water flow on the pipeline can be reduced. This stable water flow state can reduce pipeline vibration. By initially buffering and changing the flow velocity and direction, the impact of the medium on the valve body and pipeline can be reduced, which can reduce the wear rate of the pipeline. Slowing down the water flow impact helps protect various internal components of the valve body, such as the valve disc and valve seat. These components are prone to fatigue damage when subjected to strong water flow impact. This buffer design can effectively reduce the risk of damage, ensure the sealing performance and normal function of the valve body, and reduce the maintenance frequency of the valve body.

[0036] In some embodiments, the check buffer plate 24 is provided with a ring array of reinforcing ribs 25, which can increase the rigidity of the check buffer plate 24 and reduce its vibration amplitude under fluid impact, thereby reducing the noise caused by vibration.

[0037] This design, with its reinforcing ribs 25, increases the rigidity of the check buffer plate 24, reducing its vibration amplitude under fluid impact and thus reducing noise caused by vibration. The addition of the reinforcing ribs 25 makes the check buffer plate 24 more robust when facing fluid impact. When high-speed fluid flows and impacts the check buffer plate 24, the shape and position of the check buffer plate 24 can remain relatively stable due to the supporting effect of the reinforcing ribs 25.

[0038] In some embodiments, the diameter of the check buffer plate 24 is the same as the inner diameter of the water inlet pipe 11, and the check buffer plate 24 and the water inlet pipe 11 are slidably sealed together.

[0039] With this configuration, since the diameter of the check valve 24 is the same as the inner diameter of the inlet pipe 11, and the two are connected by a sliding seal, fluid leakage from the gap between the inlet pipe 11 and the check valve 24 can be effectively prevented. The matching and sliding seal between the check valve 24 and the inner diameter of the inlet pipe 11 allows for more precise control of the water flow direction. When water enters the inlet pipe 11, the check valve 24 can completely cover the cross-section of the inlet pipe 11, effectively preventing backflow.

[0040] In some embodiments, T-shaped flow buffer rings 4 are arrayed on both the inlet pipe 11 and the outlet pipe 12.

[0041] With this configuration, the T-type flow buffer ring 4 can buffer and divert the water flow, allowing the water to enter the valve body more smoothly, reducing the impact of the water flow on components such as the valve disc and valve seat, reducing the probability of water hammer, and by buffering the water flow, reducing the turbulence and eddies in the pipeline, thereby reducing the noise generated by water flow impact and eddies, and improving the noise reduction effect of the valve body.

[0042] In some embodiments, both the inlet pipe 11 and the outlet pipe 12 are provided with flanges 5 to facilitate disassembly and installation with adjacent equipment.

[0043] With this configuration, flange 5 provides a convenient connection method, facilitating the installation and disassembly of the valve body with adjacent equipment or pipelines. When maintenance, repair, or replacement of the valve body is required, the valve body can be easily separated from the pipeline simply by loosening the bolts, greatly reducing maintenance costs and time.

[0044] In some embodiments, a sound-absorbing material 3 is attached to the outer wall of the valve seat 13, and the sound-absorbing material 3 is made of porous sound-absorbing ceramic material.

[0045] With this design, the porous sound-absorbing ceramic material has a three-dimensional mesh structure. When sound is incident on the surface of the material, it causes the air in the pores to vibrate and rub against the ceramic ribs, thereby converting the sound energy into heat energy and dissipating it, effectively reducing the noise transmission inside the valve body.

[0046] The implementation principle of the noise-reducing and flow-stopping buffer valve body casting in this application embodiment is as follows: When the user controls the water flow using the valve body, the water flow is first slowed down by the T-shaped flow-slowing ring 4. The water flow comes into contact with the check buffer plate 24, which initially slows down the water flow. The water flow compresses the telescopic spring 22, causing the check buffer plate 24 to be compressed outside the inlet pipe 11. The reinforcing ribs 25 on the check buffer plate 24 increase the rigidity of the check buffer plate 24 and reduce its vibration amplitude under fluid impact, thereby reducing the noise caused by vibration. While providing initial buffering for the water flow in the inlet pipe 11, it also prevents the water flow from flowing back. Subsequently, the water flow enters the gap between the valve body shell 1 and the valve seat 13 through the inlet pipe 11. At the same time, the valve seat 13 changes the medium flow rate and direction, reducing the impact of the medium on the valve body and the pipeline, thereby reducing noise. The water flow enters the valve seat 13 through the upper end of the valve seat 13 and then flows out of the valve body from the outlet pipe 12.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
