Ceramic Double Insert Plate Valve Supplier - Gate Valve

Ceramic double plug valve supplier

Overview

Double plate ceramic pneumatic valve, also known as ceramic parallel double gate valve, dry ash valve, discharge valve, feed valve, discharge valve, pneumatic valve, is a type of ceramic gate valve. Therefore, its structural working principle is similar to that of ceramic gate valves. The valve stem drives the opening and closing member (valve plate) and the sealing surface of the valve seat to move up and down, which can connect or cut off the fluid channel. When the valve is partially opened, eddy currents are generated on the back of the gate plate, which can easily cause erosion and vibration of the gate plate, and also damage the sealing surface of the valve seat. It is difficult to repair and is usually suitable for working conditions where frequent opening and closing are not required, and the gate plate is kept fully open or closed. The ceramic track strip set on the inside of the valve cover and the assist spring set inside the three-way valve core can effectively make the left and right gate plates move tightly against the ceramic track strip without any leakage, thereby ensuring the normal operation of the valve body. The structure of this utility model is simple and easy to install and use.

The scope of use is

1. Power plant ash removal - dry ash removal system;

2. Mineral processing plant - selection and transportation of dry mineral powder materials;

3. Cement industry - conveying and discharging of dry powder materials;

4. Flour mill - flour conveying pipeline.

5. For the transportation of other high wear media such as powders or small solid particles, which often contain hard particles and fibrous dirt, this valve serves as an opening and closing device in pipeline systems and can play a good roleThe function.

Precautions and characteristics during use: The opening and closing component of the plug valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. The plug valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve has two sealing surfaces. The commonly used mode gate valve has two sealing surfaces that form a wedge shape, and the wedge angle varies with the valve parameters, usually 50. The gate of the wedge type plug valve can be made as a whole, called a rigid gate valve; It can also be made into a gate plate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate plate is called an elastic gate plate insert valve. When the valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate plate is pressed against the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface. This is called self sealing. Most plug-in valves use forced sealing, which means that when the valve is closed, the gate must be forcefully pressed against the valve seat by external force to ensure the sealing surface is sealed. The sealing structure of the plug-in valve can be divided into soft sealing and hard sealing structures.
