What is the role of Single Orifice Air Valve

Single Orifice Air Valve refers to an exhaust valve with only one orifice as the inlet and exhaust valve ports. There are two types: large port and small port. Then what is the role of Single Orifice Air Valve? Let's learn about it with the exhaust valve manufacturer.

The manufacturer of Soft Sealing Butterfly Valve will take you to know: Butterfly valve structure and common problems

The manufacturer of Soft Sealing Butterfly Valve tells you that the butterfly valve has been widely used in petroleum, chemical industry, metallurgy, hydropower and other fields as an integral part of the pipeline system switch flow control. In the known butterfly valve technology, the sealing form is mostly sealed, and the sealing material is rubber, polytetrafluoroethylene, etc. Due to structural limitations, it is not suitable for industries that are resistant to high temperature, high pressure, corrosion and wear.

Introduction of Double Eccentric Butterfly Valve

Introduction of Double Eccentric Butterfly Valve

The double eccentric butterfly valve is also called high-performance butterfly valve, which is mainly used for drainage of water works, power plants, steel smelting, chemical industry, water source spring engineering, environmental facilities construction and other systems, especially for waterway pipeline, as regulation and closure equipment. Compared with the center line butterfly valve, the double eccentric butterfly valve has higher pressure resistance, longer service life and better stability. Structural features Reasonable design, compact structure, easy assembly and disassembly, easy maintenance. Eccentric structure is adopted to reduce the friction of sealing ring and prolong the service life of valve. Completely sealed with zero leakage. It can be used in ultra-high vacuum condition. By changing the material of valve plate seal ring, butterfly plate and shaft, it can be applied to a variety of media and different temperatures. Working Principle of Double Eccentric Butterfly Valve The double eccentric butterfly valve is further improved on the basis of the concentric butterfly valve. Its structural feature is that the axis of the valve stem deviates from both the center of the disc and the body. The effect of double eccentricity enables the butterfly disc to break away from the valve seat immediately after the valve is opened, greatly eliminates the unnecessary over extrusion and scratch phenomenon between the disc and the valve seat, reduces the opening resistance distance, reduces the wear and improves the service life of the valve seat. At the same time, the double eccentric butterfly valve can also use metal seat, which improves the application of butterfly valve in high temperature field.

Bs5163 Stainless Steel Gate Valve manufacturer takes you to understand: stainless steel gate valve operation and distribution application instructions

Bs5163 Stainless Steel Gate Valve manufacturer takes you to understand: stainless steel gate valve operation and distribution application instructions

The manufacturer of Bs5163 Stainless Steel Gate Valve tells you that the gate of the stainless steel gate valve moves linearly along with the valve stem, which is called the lifting stem gate valve (also called the rising stem gate valve). The manufacturer of Bs5163 Stainless Steel Gate Valve tells you that there are usually trapezoidal threads on the lifting rods. Through the nut on the top of the valve and the guide groove on the valve body, the rotary motion is changed into linear motion, that is, the operating torque is turned into operating thrust. The manufacturer of Bs5163 Stainless Steel Gate Valve tells you that the sealing surface can be sealed only by medium pressure, that is, relying on the medium pressure to press the sealing surface of the gate against the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves use forced sealing, that is, when the valve is closed, the gate must be forced against the seat by external force to ensure the sealing performance of the sealing surface.
