Overview

Wear resistant ceramic check valve, also known as ceramic one-way valve or ceramic check valve, refers to a valve that automatically opens and closes the valve disc by relying on the flow of the medium itself to prevent the medium from flowing back. It is mainly suitable for transporting slurry, mortar, and sewage in industries such as mining, metallurgy, power, chemical, and sewage discharge, with a working temperature of ≤ 280 ℃ and a pressure not exceeding 4.0MPa.

Product Details

Wear resistant ceramic check valve

Working Principle:

Ceramic check valve, the opening and closing parts are opened or closed by the flow and force of the medium to prevent the medium from flowing back. The driving method can be automatic or pneumatic, the connection method can be flange or welding, the structural form can be rotary opening, and the sealing structure can be soft seal or hard seal. This product is mainly designed for the ash discharge system of thermal power plants. The valve disc is in a natural downward state inside the valve body. When the pump is running normally, the pressure in the pipeline pushes the valve disc to rotate along the axis of the valve stem and open, allowing the medium to pass through; When the pump is stopped, the valve disc automatically closes due to its own gravity and the pressure of the medium backflow to prevent the medium from flowing back. It belongs to the category of automatic valves and is mainly used on pipelines with one-way flow of media. It only allows the media to flow in one direction to prevent accidents.

Wear resistant ceramic check valve

Advantage:

1. All parts in contact with the medium are structural ceramic materials, with chemical stability and hardness * (Rockwell hardness HRC90), second only to diamond;

2. The excellent wear resistance of ceramics makes this valve durable, reliable, and has a long service life, which is 2-4 times that of titanium alloy valves and Monel valves;

3. This valve has excellent wear resistance, corrosion resistance, erosion resistance, and good thermal insulation properties;

4. Can be used for high hardness granular media; Can be used for various complex working conditions, more professional!

5. Can be used in media with soft particles but also corrosive media; Low cost, long service life, and high cost-effectiveness;

6. For the above-mentioned media, this valve has * advantages and is currently * suitable for this type of media valve.

Ceramic check valves can be divided into three types based on their structure: lift check valves, swing check valves, and butterfly check valves. Lift check valves can be divided into two types: vertical and straight through. Swing check valves are divided into three types: single disc, double disc, and multi disc. Butterfly check valves are disc double disc and disc single disc. The above types of check valves can be divided into four connection forms: threaded connection, flange connection, welding, and clamp connection.
