Description

Technical Field

[0001] This utility model belongs to the field of float valve technology, specifically relating to a high-protection flange float valve. Background Technology

[0002] As a core actuator in fluid transport systems for controlling medium flow and flow, float valves are widely used in key fields such as chemical, petrochemical, energy (e.g., thermal power and nuclear power auxiliary networks), water treatment, and municipal engineering. Their operational stability, sealing reliability, and operational safety directly determine the continuity of the entire fluid system's operation, media utilization rate, and production safety level.

[0003] Currently, mainstream float valves on the market have weak anti-misoperation and anti-interference capabilities in terms of structural design and performance, resulting in poor operational stability. Industrial sites commonly experience interference factors such as pipeline vibration (e.g., resonance caused by pump operation or fluid impact) and human error. Traditional float valves lack a reliable valve core locking mechanism, and pipeline vibration can easily cause the valve core to rotate unexpectedly, leading to accidental medium flow or disconnection. Although some valves have a simple locking structure, manual adjustment and reset are required, making operation complex and difficult to adapt to dynamic operating conditions (e.g., the locking state needs to be adjusted in real time according to changes in medium pressure).

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figure 1-4 This is an embodiment of the present invention, which provides a high-protection flange float valve, comprising: The ball valve assembly 100 includes a valve body 101, a valve core 102 rotatably mounted inside the valve body 101, a main connector 103 fixedly connected to one end of the valve body 101, and a secondary connector 104 fixedly connected to the other end of the valve body 101. The main connector 103 and the secondary connector 104 are provided with through holes that cooperate with the valve core 102, and the inner walls of the main connector 103 and the secondary connector 104 are provided with relief grooves that cooperate with the valve core 102. The valve core 102 is in rotatable contact with the relief grooves on the inner walls of the main connector 103 and the secondary connector 104. The adjusting assembly 200 includes a column 201 fixedly connected to the end of the valve body 101, a valve stem 202 rotatably connected to the center of the column 201, a cover 203 fixedly connected to the side wall of the column 201, and a plug 204 slidably inserted into the inside of the cover 203. The valve body 101 is provided with a slot for cooperating with the plug 204. The end of the plug 204 is inserted into the middle of the slot inside the valve body 101, and the end of the plug 204 extends to the side wall of the valve core 102.

[0019] The valve body 101 is a through-hole structure with two ends. An internal mounting cavity is machined to fit the valve core 102, ensuring a tight seal during valve core 102 rotation. The valve core 102 is a solid sphere with a hole. A flow channel (with a flow channel diameter matching the nominal pipe diameter) is machined at the center of the sphere to match the through holes of the main connector 103 and the auxiliary connector 104. The valve core 102 rotates into contact with the clearance grooves of the main connector 103 and the auxiliary connector 104. The fit between the sphere and the inner wall of the clearance groove prevents leakage of the medium from the gap between the valve core and the connector. Simultaneously, the rotation of the sphere allows for rapid switching of the pipeline's on / off state. The main connector 103 and the auxiliary connector 104 are the connection interfaces between the valve body 101 and the external pipeline. When the valve core rotates, the clearance groove provides rotation space for the valve core 102 and forms a surface seal through the tight contact between the groove wall and the surface of the valve core 102, preventing the medium from leaking from the gap between the connector and the valve core. In addition, bolt holes are machined at the flange end of the connector to facilitate precise docking with the flange of the external pipeline. Gaskets can be added to the mating surface to further enhance the seal. The regulating component 200 is used to improve the stability and safety of valve operation, and at the same time protects the internal components through the closed structure. The column 201 is fixed to the end of the valve body 101 (located directly above the valve core) through a flange connection, and a valve stem mounting hole is machined in its center (the hole is filled with a packing seal or a mechanical seal). The core function of the column 201 is to provide rotational support for the valve stem 202, and simultaneously prevent media leakage from the gap between the valve stem and the valve body through a sealing structure (preventing the media from rushing upwards along the valve stem). It serves as the carrier connecting the valve body 101 to external operating components. The lower end of the valve stem 202 is fixed to the valve core 102 via a key or pin connection. Rotating the valve stem drives the valve core to rotate synchronously, realizing the switching of media flow. Simultaneously, the sealing structure between the valve stem 202 and the column 201 (such as a stuffing box) prevents media leakage along the outer wall of the valve stem, further enhancing protective performance. The cover 203 is encapsulated on the side wall of the column 201. Moving the insert 204 so that its end abuts against the side wall of the valve core 102 locks the rotational position of the valve core (preventing accidental rotation due to pipeline vibration). When the valve core needs to be rotated, pulling the insert outward releases the lock, making operation convenient. Alternatively, a flexible material can be used to scrape and clean the side wall of the valve core 102, ensuring smooth rotation of the valve core 102.

[0020] Specifically, a one-way valve 205 is threadedly connected to the side wall of the cover 203. The one-way valve 205 communicates with the inside of the cover 203. A tension spring 206 is fixedly connected inside the cover 203. The end of the tension spring 206 is fixedly connected to the side wall of the insert block 204.

[0021] The medium can be introduced into the housing 203 through the one-way valve 205, and the medium pushes the insert 204 to move, adjusting the working state of the float valve. At this time, the tension spring 206 will be pulled, so that the tension spring 206 generates a certain elastic potential energy, disconnecting the medium connection. The tension spring 206 will release the previously stored elastic potential energy and pull the insert 204 back to the normal position.

[0022] Furthermore, the side wall of the insert 204 is provided with a stepped edge structure, and the stepped edge of the side wall of the insert 204 slides in contact with the inside of the cover 203.

[0023] The stepped edge of the insert 204 slides in contact with the inside of the cover 203, which not only restricts the sliding direction of the insert (moving only along the axial direction) but also prevents the insert 204 from coming out of the inside of the cover 203.

[0024] Furthermore, a handle 207 is fixedly connected to the end of the valve stem 202, and a rubber sleeve is installed at the end of the handle 207.

[0025] The handle is fitted with a rubber sleeve with anti-slip texture. This improves grip comfort and prevents slipping during operation. It also insulates the heat of the medium (preventing high-temperature medium from being transferred to the handle through the valve stem and causing burns) and has a certain degree of insulation (suitable for pipeline systems in energized environments), thus enhancing operational safety.

[0026] Preferably, a limiting block 208 is fixedly connected to the side wall of the handle 207, and a connecting plate 209 that cooperates with the limiting block 208 is fixedly connected to the end of the column 201. A limiting groove is provided on the side wall of the connecting plate 209, and the end of the limiting block 208 is inserted into the inner side of the limiting groove on the side wall of the connecting plate 209.

[0027] The limiting block 208 is installed on the side wall of the handle 207, with its end inserted into the middle of the limiting groove. The handle 207 cannot continue to rotate, thus maintaining the stability of the handle 207's position and preventing the ball valve from closing unexpectedly.

[0028] It should be noted that the connecting plate 209 has a threaded connection to a limit post 210 on its side wall, and the limit post 210 is located on the side wall of the handle 207.

[0029] The limiting post 210 is used to limit the rotation range of the handle 207, preventing excessive rotation from causing wear on the sealing surface of the valve core and the connector relief groove, or damage to the valve stem and sealing structure, thus extending the service life of the valve. Preferably, sealing rings are symmetrically arranged on the side wall of the valve body 101, and the sealing rings on the side wall of the valve body 101 are in close contact with the inner walls of the main connector 103 and the auxiliary connector 104, respectively.

[0030] Among them, the valve body 101 has symmetrically reserved sealing ring installation grooves on its side wall, and the groove depth matches the sealing ring cross-section to prevent leakage of the conveyed medium.

[0031] In use, the ball valve assembly 100 serves as the core channel for media flow. The valve core 102 is rotated to achieve on / off switching. When media flow is required, the handle 207 is rotated to drive the valve stem 202 (the lower end of the valve stem 202 is fixed to the valve core 102 via a key or pin connection). The valve stem 202 drives the valve core 102 to rotate, making the flow channel of the valve core 102 completely aligned with the internal through holes of the main connector 103 and the auxiliary connector 104. The media can then enter from the main connector 103 and flow out from the auxiliary connector 104 through the flow channel of the valve core 102. When media needs to be cut off, the handle 207 is rotated in the opposite direction, completely disaligning the flow channel of the valve core 102 with the through holes of the main connector 103 and the auxiliary connector 104. At this time, the surface of the valve core 102 is tightly fitted with the clearance grooves on the inner walls of the main connector 103 and the auxiliary connector 104, blocking media flow through the surface sealing structure and achieving rapid on / off switching. The column 201 is fixed to the end of the valve body 101 (directly above the valve core 102) by a flange. A packing seal or mechanical seal is installed in the mounting hole of the valve stem 202 at its center. On the one hand, it provides stable rotation support for the valve stem 202, and on the other hand, it prevents the medium from flowing upward along the gap between the valve stem 202 and the column 201, thus preventing the medium from leaking to the external operating area.

[0032] The cover 203 is encapsulated on the side wall of the column 201. The internal insert 204 is held in its initial state by the tension spring 206 (the end of the insert 204 can abut against the side wall of the valve core 102). At this time, the valve core 102 is locked, effectively preventing the valve core 102 from being accidentally rotated due to pipeline vibration. If it is necessary to unlock and rotate the valve core 102, the insert 204 can be pulled outward to release the lock. In addition, the medium can be introduced into the cover 203 through the one-way valve 205 on the side wall. The medium pressure pushes the insert 204 to move (synchronously stretching the tension spring 206 to store elastic potential energy), flexibly adjusting the locked / unlocked state of the valve core 102. When the medium supply is disconnected, the tension spring 206 releases its elastic potential energy, pulling the insert 204 to automatically reset to the initial position. No manual adjustment is required, making operation convenient. Meanwhile, the stepped edge of the side wall of the insert 204 slides in contact with the inside of the cover 203, which not only restricts the insert 204 to move only along the axial direction (ensuring precise locking), but also prevents the insert 204 from falling out of the cover 203, thus ensuring the integrity of the component.

[0033] When the handle 207 is rotated to the fully open (valve core 102 flow channel aligned with the through hole) or fully closed (flow channels misaligned) position, the limit block 208 is inserted into the limit groove of the connecting plate 209, forcibly restricting the handle 207 from continuing to rotate, avoiding excessive rotation of the valve core 102 that could cause misalignment of the sealing surface; the limit post 210 on the connecting plate 209 further limits the rotation range of the handle 207, preventing wear of the sealing surface between the valve core 102 and the clearance groove, and damage to the valve stem 202 and the sealing structure, thus protecting the core components from the operating end.

[0034] In summary, the triple-sealing structure provides comprehensive leakage protection, meeting the protection requirements of harsh operating conditions such as high pressure and high corrosion, with an extremely low risk of leakage. The locking function of the insert block 204 effectively resists the impact of pipeline vibration on the valve core 102, preventing unexpected medium flow interruption, which is especially suitable for scenarios with high process stability requirements, such as chemical and energy industries. The cooperation between the limit block 208 and the limit groove of the connecting plate 209, and the limit post 210 on the connecting plate 209, form a double limit design, which not only prevents wear on the sealing surface of the valve core 102 and damage to the valve stem 202 caused by excessive rotation of the handle 207, but also ensures that the valve core 102 can be accurately positioned (fully opened / closed) with each rotation, avoiding seal failure or insufficient flow due to operational deviation, and ensuring long-term stable operation of the valve. The insert 204 can be replaced with a flexible material as needed to scrape and clean the side wall of the valve core 102, avoiding the valve core 102 from getting stuck due to the adhesion of impurities, and is suitable for media conveying scenarios containing a small amount of impurities; the media drive design of the one-way valve 205 can be linked with an external control system to realize semi-automatic adjustment of the valve core 102 state, which is suitable for industrial automated pipeline systems and improves scenario adaptability.
