Overview

Product Overview: Umbrella Gear Concealed Plate Knife Gate Valve and Stainless Steel Concealed Rod Knife Gate Valve. The valve body is a flat plate-like structure, connected to the pipeline clamp. The gate plate adopts a single gate plate, with one side sealed with the valve body seat and the back side in wedge-shaped contact with the other side of the valve body. The sealing surface is in contact with the medium flow

Product Details

Product Overview:

The umbrella gear concealed blade gate valve and stainless steel concealed rod knife gate valve have a flat plate-shaped structure with a clamped connection to the pipeline. The gate plate adopts a single gate plate, with one side sealed to the valve body seat and the back side in wedge-shaped contact with the other side of the valve body. The sealing surface is opposite to the flow direction of the medium. The wedge-shaped contact structure is equipped with wedge-shaped compression blocks on the back of the sealing surface, and an adjusting top wire is provided at the corresponding compression block on the other side of the valve body.

Product advantages:

It has the advantages of short length and light weight of the valve body structure, the sealing surface of the valve seat can be protected from medium erosion, the sealing surface is uniformly compressed, tightly adhered, and can scrape away dust particles, tar, etc. on the sealing surface of the valve seat during the closing process. It is also easy to discharge and prevents medium leakage. Suitable for use in gas pipelines containing dust or tar.

Application scope:

Mining and steel industry - used for coal slurry, filter residue slurry, etc.

Purification device - used for wastewater, mud, dirt, and clarified water with suspended solids.

Paper industry - used for any concentration of pulp, feed water mixture.

Sugar industry - used for sugar beet washing, syrup, juice extraction, fruit juice, etc.

Food industry - used for washing and rinsing equipment, grain conveying equipment, malt extract, etc.

Power plant ash removal - used for ash slurry.

Usage and characteristics:

DMZ573W umbrella gear knife type gate valve is widely used in various fields such as chemical industry, coal, sugar production, sewage, papermaking, fly ash treatment, bulk material transportation, food and beverage industry, and under harsh environmental conditions. It is an ideal sealed valve. Knife gate valves are particularly suitable for regulating and throttling pipelines in the paper industry. According to the needs, multiple flushing ports can be set around the valve body, which can be directly flushed with air, steam or water to prevent sediment from gradually accumulating. It is particularly suitable for fluids with difficult input.

1. Adopting a clamp type structure, it has a small volume, light weight, low flow resistance, and is easy to install and maintain.

2. A completely open channel can prevent the medium from depositing inside the valve.

3. The newly developed U-shaped sealing ring can ensure good sealing performance of the valve.

4. The external sealing of the gate is achieved by a sealing strip with elasticity embedded in the valve body, which can be adjusted with the help of screws and pressure plates.
