American standard gate valve application:

Vacuum distillation (also known as vacuum distillation) is an important method to separate and purify compounds, especially for the separation and purification of high-boiling substances and compounds from thermal decomposition, oxidation or polymerization without reaching the boiling point in atmospheric distillation. Distillation device, generally called atmospheric decompression device. Atmospheric decompression distillation unit is one of the most important units of oil refining enterprises, refining enterprises how many tons/year is the capacity of atmospheric distillation unit of atmospheric tower annual processing capacity, we produce the American standard valve in the process requirements of oil refining plays a vital role. The composite materials used are super resistant to corrosion and are tailored for custom production.

Product features:

For a long time, the American standard gate valve used in the market is generally leaking or rusting. The elastic seat seal gate valve produced by our company introduced high-tech American standard gate valve manufacturing technology has overcome the defects of poor sealing and rusting of the general American standard gate valve. The elastic seat seal American standard gate valve uses the compensation effect of slight elastic deformation of the elastic gate to achieve good sealing effect, the American standard gate valve has the advantages of light switch, reliable sealing, good elastic memory and service life. It can be widely used in tap water, sewage, construction, petroleum, chemical industry, food, medicine, textile, electric power, shipbuilding, metallurgy, energy system and other pipelines as regulating and intercepting devices.
 
 

Light weight, good sealing The body is made of advanced forging, the weight of the traditional gate valve is reduced by about 20% to 30%, and the installation and maintenance are convenient. Traditional gate valves are often caused by foreign objects such as stones, wood blocks, cement, iron filings, sundries, etc. depositing in the groove at the bottom of the valve after the water washing pipe is opened, which is easy to cause water leakage phenomenon that cannot be closed tightly. The bottom of the elastic seat seal gate valve adopts the same flat bottom design as the water pipe machine, which is not easy to cause sundries to deposit and make the fluid unimpeded.

Precision forging valve body, low fluid resistance The valve body adopts precision forging, and the precise geometric dimensions make the valve body inside without any finishing to ensure the sealing of the valve. The fluid resistance is small, and the sealing surface is brushed and eroded by the medium.

Easy opening and closing, medium flow is not restricted The structure is simple, the structure length is short, the manufacturing process is good, and the application range is wide. Opening and closing is labor-saving. Medium flow is not restricted, not spoiler flow, do not reduce the pressure.

the working principle of us standard gate valve:
American standard gate valve by the valve plate up and down movement, control valve opening. The inspection standard of American standard valve is inconsistent with the national standard valve. The valve plate is like a gate. When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, only rely on the medium pressure to press the sealing surface of the gate to the other side of the valve seat to ensure that the sealing surface is sealed, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, it is necessary to rely on the external force to press the gate to the valve seat to ensure the sealing surface. The type of gate valve, according to the sealing surface configuration can be divided into wedge gate valve and parallel gate valve.
