Description

Technical Field

[0001] The utility model relates to a buried fully welded ball valve structure, belonging to the technical field of buried ball valves. Background Technique

[0002] In modern industry and municipal engineering, buried ball valves are widely used in fields such as oil transportation, water treatment, and heating systems due to their advantages of compact structure, good sealing performance, simple operation, and convenient maintenance. Buried ball valves are usually installed underground, not easily affected by the external environment, and have good concealment and safety. However, traditional buried ball valves have some technical limitations. For manually operated ball valves, operators may need to directly reach the site for operation, which is inconvenient in bad weather or inaccessible locations. Many buried ball valves lack effective automatic control and monitoring systems and cannot be monitored in real time and cut off emergently in some special application scenarios. After retrieval, it is found that the Chinese patent with the publication number CN220505862U discloses a buried high-pressure ball valve. The operator applies force through the control handle, and the force is transmitted to the extension rod through the extension mechanism. The extension rod drives the valve stem to rotate, and the rotation of the valve stem drives the sphere in the ball valve body to rotate, aligning the hole on the sphere with the pipeline, allowing the fluid to pass through, and the valve opens. The operator applies force in the opposite direction through the control handle, drives the valve stem to rotate through the extension mechanism and the extension rod, and the rotation of the rod makes the hole on the sphere perpendicular to the pipeline, cutting off the fluid flow, and the valve closes. This patent requires manual opening and closing of the valve, and the operator needs to be on site, which may be not timely enough in some cases. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a buried fully welded ball valve structure that can well control the automatic opening and closing of the valve and can detect the pressure change of the surrounding environment to prevent accidents.

[0004] To solve the above technical problem, the technical solution of the utility model is: a buried fully welded ball valve structure, characterized by comprising:

[0005] An outer housing, with a connection port provided at the top of the outer housing, and a first inlet and a first outlet provided on the outer housing;

[0006] A ball valve body, installed inside the outer housing;

[0007] A control valve stem, installed on the ball valve body and extending outward through the connection port. A control motor is provided at the top of the control valve stem, and the control motor is adapted to drive the control valve stem to rotate and drive the ball valve body to rotate so that the first inlet communicates with the first outlet;

[0008] A pressure sensor is installed on the outer housing, and the pressure sensor is adapted to detect the pressure around the outer housing after the outer housing is buried underground.

[0009] Furthermore, in order to increase the protection of the control valve stem, a valve stem housing is also sleeved on the control valve stem, and the valve stem housing is connected to the connection port.

[0010] Furthermore, to ensure the sealing performance at the connection between the valve body and the outside, a first flange is provided at the bottom of the valve stem housing, a second flange is provided at the connection port, and the first flange is adapted to be connected to the second flange.

[0011] Furthermore, a gasket is provided between the first flange and the second flange.

[0012] Furthermore, a control platform is provided at the top of the valve stem housing, and the control motor is installed on the control platform.

[0013] Furthermore, in order to control the operation of the valve and improve the operation efficiency, a control component is also provided on the control platform. The control component includes a controller, the controller is connected to the pressure sensor, and the controller is adapted to receive the pressure data detected by the pressure sensor;

[0019] 1. In the present utility model, the controller sends a signal to the control motor, the control motor starts to work, the control motor drives the control valve stem to rotate.

[0020] Control the motor to drive the control valve stem to rotate in the reverse direction, and the ball valve body rotates accordingly. When the ball valve body rotates to the position where the hole on the sphere is perpendicular to the inlet and the outlet, the fluid flow is cut off and the valve closes.

[0021] 2. In the present utility model, when the entire valve body structure is buried in the basement, the pressure sensor continuously monitors the surrounding pressure and transmits the data to the controller. If the subsequent monitored pressure data exceeds the preset safety range, the controller will activate the alarm to send an alarm signal to remind the operator or automatically take corresponding safety measures.

When the operator needs to conduct a random inspection of the water quality, use the handle switch to open the outlet of the sampling pipe, and the fluid sample flows out through the sampling pipe, and then it can be collected and analyzed. After the detection is completed, just close the handle switch. Brief Description of the Drawings

[0027] In order to make the content of the present utility model easier to be clearly understood, the following further details the present utility model according to specific embodiments and in conjunction with the drawings.

[0028] As Figures 1-4 shown, a buried fully welded ball valve structure includes:

[0029] An outer housing 1, with a connection port provided at the top of the outer housing 1, and a first inlet 11 and a first outlet 12 provided on the outer housing 1;

[0030] A ball valve body, which is installed inside the outer housing 1;

[0031] A control valve stem 2, which is installed on the ball valve body and extends outward through the connection port. A control motor 3 is provided at the top of the control valve stem 2. The control motor 3 is adapted to drive the control valve stem 2 to rotate and drive the ball valve body to rotate so that the first inlet 11 communicates with the first outlet;

[0032] The pressure sensor 4 is installed on the outer housing 1, and the pressure sensor 4 is adapted to detect the pressure around the outer housing 1 after the outer housing 1 is buried underground.

[0033] Specifically, as Figures 1-4 shown, a valve rod housing 21 is also sleeved on the control valve rod 2. The valve rod housing 21 is connected to the connection port. The arrangement of the valve rod housing 21 avoids damage to the control valve rod 2 caused by impacts or scratches.

[0034] Specifically, as Figures 1-2 shown, a first flange 51 is provided at the bottom of the valve rod housing 21, and a second flange 52 is provided at the connection port. The first flange 51 is adapted to be connected to the second flange 52.

[0035] Specifically, a gasket is provided between the first flange 51 and the second flange 52.

[0036] In this embodiment, the first flange 51 and the second flange 52 are fixed together by bolts or other fasteners to form a firm connection, ensuring the sealing performance during the operation of the buried ball valve. The flange connection also facilitates the installation, disassembly, and maintenance of the valve.

[0037] Specifically, as Figures 1-4 shown, a control platform 6 is provided at the top of the valve rod housing 21, and the control motor 3 is installed on the control platform 6.

[0038] Specifically, as Figures 1-4 shown, a control component is also provided on the control platform 6. The control component includes a controller 7. The controller 7 is connected to the pressure sensor, and the controller 7 is adapted to receive the pressure data detected by the pressure sensor 4;

[0039] The controller 7 is connected to the control motor 3, and the controller 7 is adapted to control the start and stop of the control motor 3.

[0040] Specifically, the control component further includes an alarm. The controller 7 is adapted to control the alarm to emit an alarm signal when the detected pressure data exceeds the preset safety range.

[0041] Specifically, as Figures 1-3 shown, the structure of the buried fully welded ball valve further includes a sampling pipe 8. The sampling pipe 8 is installed on the outer housing 1 and extends out of the ground. The sampling pipe 8 is adapted to extract a fluid sample from the outer housing 1 for analysis.

[0042] Specifically, as Figures 1-3 shown, a handle switch 81 is provided at the outlet of the sampling pipe 8.

[0043] In this embodiment, the controller 7 sends a signal to the control motor 3, causing the control motor 3 to start working. The control motor 3 drives the control valve stem 2 to rotate. Since the control valve stem 2 is connected to the ball valve body, the ball valve body rotates accordingly. There is a connection channel provided on the ball valve body. The control valve stem 2 drives the ball valve body to rotate so that the connection channel communicates with the first inlet 11 and the first outlet 12, allowing the fluid to pass through and the valve to open.

[0044] The control valve stem 2 drives the ball valve body to rotate so that the connection channel is not in communication with the first inlet 11 and the second inlet 12, cutting off the fluid flow and closing the valve.

[0045] The control motor 3 drives the control valve stem 2 to rotate in the reverse direction, and the ball valve body rotates accordingly. The ball valve body rotates to a position where the hole on the sphere is perpendicular to the first inlet 11 and the first outlet 12, cutting off the fluid flow and closing the valve.

[0046] When the entire valve body structure is buried in the basement, the pressure sensor 4 continuously monitors the surrounding pressure and transmits the data to the controller 7. If the subsequent monitored pressure data exceeds the preset safety range, the controller will activate the alarm to send an alarm signal, alerting the operator or automatically taking corresponding safety measures.
