Description

Technical Field

[0001] This utility model relates to the field of safety gate valve technology, and in particular to a multifunctional self-locking safety gate valve. Background Technology

[0002] Traditional safety gate valves are a common type of shut-off and regulating valve, widely used in industrial pipeline systems to control fluid flow and provide safety protection. They achieve fully open, fully closed, or partially open states by opening and closing a lifting or rotating gate within the valve body, thereby enabling rapid shut-off or stable regulation.

[0003] However, traditional safety gate valves usually rely on the actuator to directly control the valve position, which can easily lead to return or misalignment when there is a power outage, vibration, or abnormal control signal, increasing the risk of misoperation. In addition, they have low tolerance to pollutants such as particulate matter and flocs, which can easily bring pollutants into the sealing surface and shorten the sealing life.

[0004] Therefore, those skilled in the art have provided a multifunctional self-locking safety gate valve to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional self-locking safety gate valve. This safety gate valve is equipped with a self-locking sealing mechanism. Under the elastic reset of the return spring, the arc-shaped self-locking block can control the self-locking tooth groove to mesh tightly with the self-locking gear, thereby enabling the rotating shaft to control the self-locking gear to always rotate in one direction. This prevents the valve from returning to its original position without unexpected force, significantly reducing the risk of misoperation. It also reduces the reciprocating motion of the rotating shaft, lowers the wear rate of the seals, and extends the service life of the sealing pair and the valve body. Furthermore, the valve body mechanism is divided into first and second valve tubes, which can be disassembled and replaced according to the length of use, facilitating regular inspection of the seals and maintenance of the corrosion-resistant coating, thus improving the service life of the seals and the gate valve body.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A multifunctional self-locking safety gate valve includes a valve body mechanism. The valve body mechanism includes a first valve tube, and a second valve tube is fixedly connected to the outer wall of the rear end of the first valve tube. A conveying groove is opened in the middle of the outer wall of the first valve tube and the second valve tube on the side close to each other. A rotating groove is opened in the middle of the inner wall of the conveying groove. A rotating block is rotatably connected to the inner wall of the rotating groove. A rotating shaft is fixedly connected to the center of the upper surface of the rotating block. The valve body mechanism is internally equipped with a self-locking sealing mechanism, which includes a self-locking gear, a fixed flange, a sealing block, a sealing groove, and a placement seat. A fixed block is fixedly connected to the middle of the upper surface of the placement seat, and a positioning ring is engaged with the outer wall of the fixed block. An adjusting seat is fixedly connected to one side of the outer wall of the placement seat, and a positioning screw is threaded into the outer wall of one side of the adjusting seat.

A conical block is fixedly connected to the outer wall of one side of the limiting slider. A threaded groove is formed in the middle of the outer wall of the other side of the limiting slider. An adjusting screw is threaded into the inner wall of the threaded groove. A self-locking groove is formed in the middle of the inner wall of the placement seat. Multiple return springs are fixedly connected to the middle of the inner wall of the self-locking groove. An arc-shaped self-locking block is hinged to the inner wall of the self-locking groove. A conical groove is formed on the outer wall of one side of the arc-shaped self-locking block, and multiple self-locking tooth grooves are formed on the inner wall of the arc-shaped self-locking block. The valve body mechanism is provided with a filter mechanism at both the front and rear ends. The filter mechanism includes a mounting slot. The front end of the inner wall of the mounting slot is provided with a fixing slot. The inner wall of the mounting slot is engaged with a mounting frame. The rear end of the inner wall of the mounting frame is fixedly connected with a metal filter screen.

[0007] Through the above technical solution, the safety gate valve is equipped with a filtration mechanism, which reduces the possibility of larger particles entering the valve body through the filtration and interception of stainless steel metal filter screen, thereby reducing the possibility of particles damaging the internal seals of the valve body, thus reducing the risk of leakage and seal fatigue, and extending the valve body sealing life.

[0008] Furthermore, the first valve tube is fixedly connected to the first valve tube by a fixed flange, and the fixed flange is fixedly connected to both sides of the outer wall of the first valve tube that are close to each other. Through the above technical solution, the first valve tubes can be connected and fixed together by bolts using a fixed flange.

[0009] Furthermore, a hexagonal locking block is fixedly connected to the middle of the upper surface of the rotating shaft, and a spherical gate is fixedly connected to the middle of the outer wall of the rotating block; The above technical solution enables users to use tools such as wrenches to engage with the hexagonal locking block, thereby controlling the spherical gate to open or close.

[0010] Furthermore, the self-locking gear is fixedly connected to the middle part of the outer wall of the rotating shaft, and the self-locking gear meshes with the self-locking tooth groove; The above technical solution enables the rotating shaft to control the self-locking gear to perform unidirectional rotational adjustment.

[0011] Furthermore, the sealing block is fixedly connected to the outer wall of the rear end of the first valve tube, and the sealing groove is formed on the outer wall of the front end of the second valve tube; The above technical solution improves the sealing effect when the first valve tube and the second valve tube are fixed together.

[0024] Working principle: First, the first valve pipe 101 and the second valve pipe 102 of the valve body mechanism 1 are fixedly installed between suitable pipelines via flanges. A rotating wrench is engaged with the hexagonal locking block 107 to rotate the spherical gate 108, thereby opening the flow of the liquid medium. Simultaneously, the meshing between the self-locking gear 201 and the self-locking tooth groove 2021 ensures that the user can only rotate along the direction of the teeth. The elastic reset of the return spring 2018 reduces the possibility of the spherical gate 108 reversing. After adjustment, the gate is locked. The positioning screw 2011 presses and positions the arc-shaped self-locking block 2019 to prevent the self-locking gear 201 from disengaging from the self-locking tooth groove 2021. Alternatively, the arc-shaped self-locking block 2019 can be unfolded outward by rotating the adjusting screw 2016 to engage the tapered groove 2020 with the tapered block 2014, thereby completing the reverse rotation and reset of the spherical gate 108. Finally, the components inside the valve body mechanism 1 can be replaced and repaired by disassembling the first valve tube 101 and the second valve tube 102 to reduce the possibility of damage to the sealing effect.
