Valves have different effects according to their structure. Today, let the editor of Tianjin butterfly valve manufacturer show you the structural characteristics of ventilation butterfly valve.   Ventilation butterfly valve is a valve made of steel plate welding. It has the characteristics of small size, light weight and easy installation, and because of its small flow resistance and large flow, it will not be affected by high temperature expansion. Its driving torque is small and the switch is very flexible, so it is very convenient to operate. It is deeply loved by people in the industry.   The structural characteristics of the ventilation butterfly valve. The structure of the ventilation butterfly valve is welded by the centerline butterfly plate and the short structural steel plate, so there are no components such as connecting rods and bolts inside, and there will be no components during use. Problem, so the failure rate is very low. It is very convenient to use. It is a reliable valve device.   And because its sealing system uses metal sealing, although the sealing effect is not as good as the elastic seal, the service life is longer than that of the elastic seal, and it has the characteristics of high temperature resistance. Therefore, it is widely used in building materials, electric power, metallurgy and other industries. In the medium conveying pipeline whose temperature is not higher than 300 degrees, the connection and closing adjustment function can be realized. This butterfly valve can also be specially customized according to the needs of customers, which is very user-friendly.   Because the gap between the butterfly plate and the valve body of the ventilation butterfly valve is large, there is enough room for expansion, so it can effectively prevent thermal expansion and contraction caused by temperature changes during use, and it will not produce butterfly The board is stuck. Common butterfly valves have a variety of drive methods, including manual drive, electric drive and pneumatic drive, etc., and the choice is very large. Because of the material, this butterfly valve also has the characteristics of high temperature resistance, there is no friction when switching, and the service life is extremely long.

Butterfly valve products are widely used in industrial production pipeline control due to their convenience. However, due to the wide variety of butterfly valve products, it is very important to use the appropriate type. Today, let the editor of Tianjin butterfly valve manufacturer introduce the characteristics of stainless steel butterfly valve and wafer butterfly valve.   The stainless steel butterfly valve is mainly composed of a valve body, a valve stem, a butterfly plate and a sealing ring. The valve body is cylindrical with a short axial length and a built-in butterfly plate. It is a kind of valve that the disc type disc plate reciprocates about 90° to open, close or adjust the medium flow. When the butterfly valve is required to control the flow, the specification and type of the butterfly valve should be selected correctly to avoid inaccurate flow control. Stainless steel butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.   The butterfly plate of the wafer butterfly valve is installed in the diameter direction of the pipeline, and it mainly plays the role of cutting off and throttling on the pipeline. The opening and closing part of the wafer butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. Wafer butterfly valve adopts worm gear reducer, which can not only make the butterfly plate have self-locking ability, make the butterfly plate stop at any position, but also improve the operation performance of S valve. The valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy and fast to operate, but also has good flow regulation and closing and sealing characteristics at the same time. The wafer butterfly valve is connected between two pipe flanges with stud bolts.

Stainless steel products have been widely used in life. Because of the unique properties of stainless steel, this steel has been quickly and universally put into use. However, in fact, stainless steel has an earlier history of industrial use. What Tianjin butterfly valve manufacturers want to share today is that stainless steel butterfly valves are used in Features in industrial production.   1. The surface of the stainless steel butterfly valve adheres to the organic juice (such as melon, vegetable, noodle soup, sputum, etc.), which forms organic acid in the presence of water and oxygen, and the organic acid will corrode the metal surface for a long time.   2. The surface of the stainless steel butterfly valve is deposited with dust containing other metal elements or attachments of foreign metal particles. In the humid air, the condensed water between the attachment and the stainless steel connects the two into a micro battery, which triggers electrochemistry. Reaction, the protective film is destroyed, called electrochemical corrosion.   3. The surface of the stainless steel butterfly valve contains acid, alkali, and salt substances (such as alkaline water and lime water splashing on the decoration wall), causing local corrosion.   4. In polluted air (such as the atmosphere containing a lot of sulfide, carbon oxide, and nitrogen oxide), the stainless steel butterfly valve will form sulfuric acid, nitric acid, and acetic acid liquid spots when it encounters condensed water, causing chemical corrosion. The above conditions can cause damage to the protective film on the stainless steel surface and cause rust.

In actual use, it will be classified according to working pressure and working temperature, and these conditions are limited to a certain extent by the nature of stainless steel.
