Deeply understand the structure, principle, and maintenance of MZ45X buried elastic seat sealing gate valve

The MZ45X buried elastic seat sealing gate valve is a commonly used industrial valve, mainly used for controlling fluid flow. It has multiple models and specifications, suitable for pipeline systems under various working conditions. This article will introduce the working principle, structural characteristics, and installation and maintenance methods of the MZ45X buried elastic seat sealing gate valve.

operational principle

The MZ45X buried elastic seat sealed gate valve mainly consists of components such as valve body, valve cover, valve disc, sealing ring, etc. When it is necessary to open or close the valve, the valve disc is moved by a driving device (such as an electric actuator) to block or flow the fluid.

The principle of elastic seat sealing is to use the elastic material (such as rubber) at the bottom of the valve disc to deform under pressure, thereby compensating for the gap between the valve disc and the valve seat, and ensuring sealing performance. This design can reduce leaks during operation, improve system stability and reliability.

Structural characteristics

The structural characteristics of MZ45X buried elastic seat sealing gate valve are as follows:

-Integrated casting: The valve body and valve cover adopt the integrated casting process, which improves the strength and durability of the structure.

-Floating Ball Core: The valve disc adopts a floating ball core design, allowing the valve to flexibly adjust flow and reduce the risk of wear and leakage.

-Bi-directional sealing: The bi-directional sealing design of the valve enables it to have good sealing performance in both forward and reverse flow.

-Special materials: The valve disc and sealing ring are made of special materials, which can be used for a long time under various working conditions without being affected.

Installation and maintenance

The installation and maintenance methods for MZ45X buried elastic seat sealing gate valve are as follows:

-Before installation, check whether the model and specifications of the valve meet the requirements and match with the pipeline system.

-During installation, ensure that the flange connection is tight to avoid leakage.

-Regularly check the wear of the valve sealing ring and replace it if necessary.

-Long term high-pressure operation should be avoided to prevent premature damage to the sealing ring.

-In winter, attention should be paid to insulation to prevent valves from freezing and cracking.

In summary, the MZ45X buried elastic seat sealing gate valve is a powerful and reliable industrial valve widely used in industries such as petroleum, chemical, metallurgy, and power. By selecting, installing, and maintaining correctly, its service life can be extended, ensuring the safe and stable operation of the system.
