Characteristics and Applications of Penetrating Knife Gate Valve

Penetrating knife gate valveIt is a type of linear motion valve that opens and closes by the lifting motion of a knife switch inside the valve body. It has the characteristics of strong cutting ability, rapid opening and closing, and no impact on pressure difference, and can be used for intercepting various media, especially for cutting media containing solid particles. At present, penetrating knife gate valves are widely used in industries such as chemical, pharmaceutical, food, and mining, and are a cost-effective fluid control product.

The knife gate valve of the penetrating knife gate valve has a circular hole of the same diameter on the knife gate valve. By opening and closing the gate valve, the circular hole on the gate valve can be completely disengaged and matched with the diameter. This can reduce the gap between the valve chamber and the gate, avoid the medium from staying or accumulating in the valve chamber, and improve the flow performance and wear resistance of the valve.

The structural components of a penetrating knife gate valve include:

-Valve body: There is a cutting edge inside the valve body, and the clamping parts of the sealing surface are located on both sides of the cutting edge.

-Knife switch: Knife switch is a movable cutting component, generally made of stainless steel material.

-Spiral rod: Connect the knife switch to the handwheel or actuator.

-Sealing ring: placed between the knife switch and the valve body to ensure sealing when closed.

-Handwheel: an operating mechanism that controls the lifting and lowering of the knife switch.

The working principle of the penetrating knife gate valve is:

-When closed, the knife switch descends and inserts into the valve body at the cutting edge under the action of the spiral rod, achieving the cutting and sealing of the liquid.

-When opened, the knife switch rises and exits the blade, allowing liquid to freely pass through the valve body.

The knife gate valve can accurately move up and down at the valve port, and cooperate with the elastic sealing ring to achieve leak free sealing, so the penetrating knife gate valve has the characteristics of strong cutting ability and good sealing performance.

The penetrating knife gate valve has the following characteristics in practical applications:

-Due to its simple structure, easy operation, and easy maintenance, it can save labor and material costs.

-Due to its good sealing performance, wear and corrosion resistance, and wide adaptability to media, it can extend its service life and ensure safety performance.

-Due to its low fluid resistance, good flow performance, and no impact on pressure difference, it can improve flow rate and efficiency.

Therefore, the penetrating knife gate valve is a recommended fluid control product.
