Description

Technical Field

[0001] The utility model relates to the technical field of pipeline joints, in particular to a straight-through terminal manual joint with good sealing performance. Background Art

[0002] A straight-through terminal manual valve is a device used to control the passage of a fluid (such as liquid or gas). It is usually composed of a handle, a valve body and a valve core. It is widely used in pipeline systems in various industries, such as industrial production, municipal engineering, building water supply and drainage systems, etc. They can be used to control the flow direction of liquid or gas, adjust the flow rate and achieve safe isolation.

[0003] For example, a straight-through terminal manual valve with publication number CN204647379U, the utility model includes a valve body, a first air vent is provided on the left side of the valve body, a second air vent is provided on the right side of the valve body, and a third air vent is provided on the upper part of the valve body. A trachea quick-insertion device is provided in the first air vent, a terminal connector is provided in the second air vent, and a manual control device is provided in the third air vent. The utility model can open or close the airflow at the output end of the manual valve by arranging a manual control device in the third air vent. When the manual control device is in the open state, the valve circulates normally. When the manual control device is in the closed state, the residual gas on the output device can flow out to the outside through the second air vent to the third air vent, i.e., the controlled device, thereby preventing the residual gas from damaging the pipeline and instrument and improving the safety during equipment maintenance.

[0004] Most of the straight-through terminal manual connector valves currently on the market, including the straight-through terminal manual valves described in the above-mentioned patent, can normally enable the valve to complete fluid transmission, but their sealing performance is relatively poor, which brings a series of potential risks and adverse effects.

[0005] First, due to sealing performance issues, fluid leakage may occur when the valve is closed, which may cause serious damage and danger to the system, especially in sensitive application environments such as chemical plants or gas transmission systems. Leakage may cause safety hazards and pose a potential threat to personnel, equipment and the environment.

[0006] Secondly, due to the inability to completely close or poor sealing, the valve may continue to leak in the closed state, resulting in energy waste and increased system operating costs. Continuous leakage leads to fluid loss, which will force the system to consume additional energy to maintain the required process flow, which will not only increase energy costs, but may also reduce the efficiency of the entire process or system.

[0007] In addition, leaked fluid may also cause corrosion, erosion or other damage to certain components. For some fragile equipment components, leaked fluid may cause corrosion, wear and other damage, affecting the normal operation of the equipment, which will increase the cost of equipment maintenance and replacement and may lead to prolonged system downtime.

[0008] In summary, there are many problems with straight-through terminal manual joints with poor sealing performance, including leakage, energy waste and equipment damage.

[0009] In view of the above problems, the utility model provides a straight-through terminal manual control connector with good sealing performance. Utility Model Content
