What is a soft seal gate valve?
Soft sealing gate valve, also known as elastic seat sealing gate valve, adopts a cavityless structure, the inner and outer surfaces of the valve body and the valve cover are sprayed with epoxy resin, and the surface of the gate plate is covered with rubber, which fundamentally eliminates the possibility of corrosion. Gate valves can be operated by lever, handwheel, electric and pneumatic as required. Its material is gray cast iron and ductile iron, and its compressive ability is also very strong, and it is suitable for water, sewage and drinking water.

What material is good for butterfly valve
Die que commonly used materials are gray cast iron, nodular cast iron, cast steel, stainless steel, these several. If the material performance is compared, there is no doubt that stainless steel butterfly valve is one of the best, because its temperature resistance, corrosion resistance and pressure resistance are better than other materials, the environment is also more suitable conditions, the cost of stainless steel butterfly valve is the highest in several materials. If only water and steam are used, grey cast iron or nodular cast iron is sufficient. If you use cast steel or stainless steel, it will increase the cost. Butterfly valve with what material, medium and pipeline has a direct relationship, including medium temperature, pressure, corrosion resistance, low room temperature environment, butterfly valve gray cast iron, ductile cast iron materials; In high temperature and high pressure environment, butterfly valve is made of cast steel; High temperature, high pressure, strong corrosion, butterfly valve made of stainless steel.

Special extension rod pneumatic knife gate for sewage treatment plant
Concealed stem wafer type knife gate valve is a new type of gate valve. It is small in size, light in weight and light in material saving. It is an ideal product for sewage, coal slurry, mud, air, slag-water mixture, water supply, papermaking, mining and other industries. Knife gate valves use metal-to-metal hard seals, or metal-to-rubber soft seals. In the process of opening and closing, the gate and sealing surface adopt a special design, which has less friction and is durable.

Take you to understand gate valve
Gate valves are generally used in large engineering projects, and their quality requirements for gate valves are very high. As long as the quality and performance of the gate valve are ensured, the safe and sustainable operation of the gate valve under various environments and conditions can be ensured. Ensuring the quality of gate valves requires responsibility first. Without a sense of responsibility, even with advanced technology, it is difficult to ensure that high-quality gate valves can be developed. Because of the tightness, durability and compression performance of the gate valve, it needs ingenuity to build. WESDOM has been building gate valves with ingenuity, and ensuring the quality of gate valves with scientific and technological strength, so that customers can use them at ease.

Interpretation of the working principle of ball valve
The opening and closing parts of the ball valve are a ball, which is rotated around the center line of the valve body to open and close the valve. The valve is opened or closed by rotating the stem. Ball valve spool is a ball with a hole, when the central axis of the hole and the central axis of the valve inlet and outlet coincide, the valve opens; When the ball is rotated 90° so that the central axis of the hole is perpendicular to the central axis of the valve inlet and outlet, the valve is closed. Ball valve switch is light, small size, can be made into a large diameter, simple structure, convenient maintenance, sealing surface and spherical surface is often in a closed state, not easy to be washed by the medium, widely used in various industries. The working principle of ball valve is as follows: When ball valve rotation 90 degrees, in the inlet and outlet should be all present spherical, so as to close the valve, cut off the flow of media. When the ball valve turns 90 degrees, in the inlet and outlet should be all present ball mouth, so as to...

The feature of the triple-eccentric multi-level metal hard-sealed butterfly valve
The triple-eccentric multi-level metal hard-sealed butterfly valve is widely used in metallurgical, electric power, petrochemical, water supply and drainage, and municipal construction and other industrial pipelines with a medium temperature of 425 ℃ or less to adjust the flow rate and load and cut off the fluid. The butterfly valve adopts a triple eccentric structure. The valve seat and the sealing surface of the disc plate are made of stainless steel with different hardness. It has good corrosion resistance and long service life. This valve has multi-level sealing function. The product conforms to the national GB/T13927-92 valve pressure. Test Standard.

What role does the check valve play in the pipeline and how does it work？
The check valve is installed in the pipeline system, and its main function is to prevent the medium from flowing back. The check valve is an automatic valve that depends on the pressure of the medium to open and close. Wafer check valve is suitable for various pipelines with nominal pressure PN1.0MPa~42.0MPa, Class150~25000; nominal diameter DN15~1200mm; working temperature -196~540℃ to prevent the medium flows back. When the water valve is closed, there are different pressures at both ends of the check valve. In addition, the inertia when the water flow suddenly stops (is suddenly blocked), so that the check valve flaps quickly swing back and forth, causing the pipeline to produce a kind of rolling stone downhill. Until the pressure on both sides of the check valve is equal. By selecting different materials, it can be applied to a variety of media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media and uric acid.

The advantages of remote water meters
Among the many smart water meters, the remote water meter is a relatively new type of smart water meter. Compared with other types of smart water meters, the remote water meter has many advantages. 1. The smart remote water meter uses a straight-through pipe section, which will not cause internal blockage during use. 2. During the installation process, because the smart remote water meter does not have any moving parts, the installation steps are relatively convenient. The main installation forms are horizontal and vertical, so there is no problem of inaccurate measurement caused by wear. 3. The intelligent remote water meter adopts a low-power design, which has a long service life and saves the trouble of replacing the battery. 4. The intelligent remote water meter can accurately measure the accuracy during the entire service cycle, and it will not change due to time. 5. The intelligent remote water meter will not be interfered by impurities, chemical substances and magnetic substances during use.
