Introduction and advantages of groove type concealed rod elastic seat sealing gate valve

The groove type concealed rod elastic seat sealing gate valve is a commonly used industrial valve, widely used in fields such as water supply and drainage, fire protection, construction, petroleum, chemical, food, and medicine. Let's take a look at its basic structure and characteristics.

Structural characteristics

The groove type concealed rod elastic seat sealing gate valve mainly consists of valve body, valve cover, valve stem, sealing ring, packing, and other parts. Among them, the valve body is usually made of cast iron or stainless steel and has concave grooves for installing and fixing pipelines. The valve cover is tightly connected to the valve body and comes with a flange for easy connection with other equipment. The valve stem is the main component for opening and closing, which is connected to the valve body through bolts and has a guide sleeve to ensure accurate positioning. The sealing ring is located at the bottom of the valve to prevent medium leakage. The packing is filled between the valve stem and valve cover, providing a sealing effect.

Working principle

When it is necessary to open or close the gate valve, human or mechanical force will cause the valve stem to rotate, thereby driving the valve disc to move. The opening or closing of the valve disc will change the flow area of the channel, thereby regulating the flow rate of the medium. Due to the elastic seat cushion below the valve disc, it can compensate for size changes caused by temperature changes or other factors, ensuring the sealing performance of the valve.

Advantages

The groove type concealed rod elastic seat sealing gate valve has multiple advantages: firstly, it has excellent sealing performance, which can effectively prevent medium leakage; Secondly, it has a compact structure and occupies little space, making it suitable for various working conditions; Again, the operation is simple and maintenance is convenient; Finally, the price is relatively economical and affordable.

Application field

The groove type concealed rod elastic seat sealing gate valve is widely used in the following fields:

1. Water supply and drainage system: used to control the flow of media such as tap water, sewage, and rainwater.

2. Fire protection system: used for fire water supply systems in fire pump rooms, fire hydrants, and other locations.

3. Building water supply system: Used for water supply systems in residential, commercial buildings, hotels, and other buildings.

4. Petrochemical system: used for transporting media such as oil, natural gas, benzene, alcohol, etc.

5. Food and pharmaceutical system: used to transport pure media required for the production process of food, beverages, drugs, etc.

Precautions

When using groove type concealed rod elastic seat sealed gate valves, the following precautions should be taken:

1. Regular inspection and maintenance: promptly identify and resolve any wear, leakage, or other issues to ensure the normal operation and safety of the valve.

2. Avoid exceeding the rated pressure: Before use, confirm the applicable pressure range of the valve to avoid damage caused by overpressure use.

3. Correct installation: Ensure that the valve is firmly connected to the pipeline to avoid loosening due to vibration or pressure changes.

4. Cleaning treatment: Regularly clean the valve to prevent the accumulation of dirt from affecting the sealing performance.

5. Pay attention to antifreeze: If the valve is installed in a low-temperature environment, appropriate insulation measures should be taken to avoid freezing damage.
