The hydraulic reversing valve MG.00.11.19.01 is an important control component commonly used in coal mill hydraulic oil stations, with excellent performance and stability. The seal kit of this valve, as its core component, plays a vital role in the normal operation of the valve, preventing leakage and ensuring the safe and stable operation of the system. Today we will introduce to you how the seal kit of the hydraulic reversing valve MG.00.11.19.01 works.

I. Composition and function of the hydraulic reversing valve seal kit MG.00.11.19.01

The seal kit of the hydraulic reversing valve MG.00.11.19.01 is mainly composed of key components such as valve core seals, O-rings, and gaskets, which play a vital role in the working process of the valve.

1. Valve core seal: The valve core seal is one of the most core seal kits in the hydraulic reversing valve. The valve core seal is closely matched with the valve core. When the valve core moves in the valve body, it can ensure that the gap between the valve core and the valve body is effectively sealed to prevent the leakage of the medium (such as hydraulic oil). At the same time, the valve core seal must also have sufficient strength and wear resistance to withstand the friction and impact force generated by the valve core during movement.

2. O-ring: O-ring is another common sealing element. It is often installed in the sealing groove of the valve body and is squeezed by the valve body and other components. O-ring has good elasticity and recovery, and can fill the tiny gap between the valve body and other components to achieve a sealing effect. The material selection of O-ring is crucial. It must be able to withstand the pressure, temperature and chemical properties of hydraulic oil, and have good wear resistance and corrosion resistance.

3. Gasket: Gasket is used to fill the gap between the various parts of the valve, such as the gap between the valve cover and the valve body. It has excellent pressure and temperature resistance to ensure that the valve does not leak the medium when it is closed. The design and selection of the gasket must take into account factors such as the working pressure of the valve, the properties of the medium, and the working environment to ensure its sealing performance and service life.

II. Working principle of the seal kit of the hydraulic reversing valve MG.00.11.19.01

The seal kit of the hydraulic reversing valve MG.00.11.19.01 realizes the sealing function of the valve through the close cooperation of the valve core seal, O-ring and sealing gasket. These seal kits play a vital role in the working process of the valve.

1. Working principle of the valve core seal: When the hydraulic reversing valve MG.00.11.19.01 is subjected to the pressure of hydraulic oil, the valve core will move along the guide groove in the valve body. During the movement, the gap between the valve core seal and the valve body is tightly fitted to form a sealing surface. When the valve core moves to a certain position, it will form a seal with the valve seat to prevent the hydraulic oil from flowing to a certain channel, thereby realizing the flow direction control of the liquid. When the valve core moves to another position, the original seal will be released and the hydraulic oil can flow to another channel. The working process of the valve core seal needs to ensure the flatness and smoothness of its sealing surface to reduce friction and wear, and also needs to consider the impact of the valve core movement speed and pressure changes on the sealing effect.

2. Working principle of O-ring: As another important sealing element of the hydraulic reversing valve MG.00.11.19.01, the working principle of the O-ring is different from that of the valve core seal. The O-ring is installed in the sealing groove of the valve body and is squeezed by the valve body and other components. Because the O-ring has good elasticity and recovery, it can fill the tiny gap between the valve body and other components, thereby preventing the medium (such as hydraulic oil) from leaking out of these gaps. The working effect of the O-ring mainly depends on the selection of its material, the design of its size and the quality of its installation.

3. Working principle of the gasket: The gasket is mainly used in the hydraulic reversing valve MG.00.11.19.01 to fill the gaps between the various parts of the valve, such as the gap between the valve cover and the valve body. The design of the gasket needs to ensure that it can withstand a certain pressure and temperature, and also needs to have good wear resistance and corrosion resistance. When the valve is closed, the gasket can fit tightly into the gap between the valve cover and the valve body to prevent medium leakage. When the valve is open, the gasket needs to be able to withstand the friction and impact force generated by the relative movement between the valve cover and the valve body.

III. Maintenance and inspection of the sealing assembly of the hydraulic reversing valve MG.00.11.19.01

In order to ensure that the sealing assembly of the hydraulic reversing valve MG.00.11.19.01 can work normally for a long time, it needs to be maintained and inspected regularly. The following is the maintenance and inspection method of the sealing assembly of the hydraulic reversing valve MG.00.11.19.01:

1. Regular inspection: Regularly inspect the hydraulic reversing valve MG.00.11.19.01 to observe whether the sealing assembly has signs of wear, aging or damage. If there is any abnormality, the sealing assembly should be replaced in time. During the inspection, special attention should be paid to the wear of the valve core seal, O-ring and gasket, and whether the matching clearance between them and the valve body and valve core is too large.

2. Cleaning and maintenance: Clean the hydraulic reversing valve MG.00.11.19.01 and the sealing assembly regularly, remove the dirt and impurities attached to the surface, and keep it clean and dry. Use appropriate cleaning agents and tools when cleaning to avoid damage to the sealing assembly. At the same time, it is also necessary to pay attention to the fact that the cleaned sealing assembly should be installed back to its original position as soon as possible to avoid long-term exposure to the air to cause aging or deformation.

3. Pay attention to installation: When installing or replacing the sealing assembly, ensure that it is installed correctly and firmly to avoid looseness or damage. Before installation, check whether the size, shape and material of the sealing assembly meet the requirements, and whether there are defects such as damage or deformation. Use appropriate tools and methods during installation to avoid damage to the sealing assembly. At the same time, it is also necessary to pay attention to the fact that the installed sealing assembly should be in the correct position and direction to ensure its normal operation.

4. Regular replacement: According to the use and working environment of the hydraulic reversing valve MG.00.11.19.01, replace the sealing assembly regularly. When replacing, choose a sealing assembly that meets the requirements to avoid using unqualified or expired products. At the same time, it is also necessary to note that the replaced seal kits should be properly inspected and tested to ensure that their performance meets the requirements.
