Description

Technical Field

[0001] The utility model mainly relates to the technical field of oil pipeline valves, in particular to a high-strength valve body for an oil pipeline pressure measuring valve. Background Art

[0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons. It is a viscous, dark brown liquid with a natural occurrence and is known as the "blood of industry". Petroleum pipeline is a pipeline used to transport petroleum, natural gas and other liquids or gases. According to different needs and uses, petroleum pipes can be divided into many different types. The most common types of petroleum pipelines are welded steel pipes, pipeline steel pipes, stainless steel pipes and polyethylene pipes. These pipes generally have properties such as resistance to high pressure, corrosion resistance and acid and alkali resistance.

[0003] The definition of a valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. The valve body is a major component of the valve. There are different mechanical manufacturing methods according to the pressure level, such as casting, forging, etc. Commonly used materials are cast iron, cast steel, stainless steel, carbon steel, plastic and copper, etc. In the casting process of the valve body, most of them are cast in one step to ensure the overall strength of the valve body. Since these high-strength valve bodies are made of metal, the thermal conductivity of the metal is good. In low temperature weather (especially in the northern region), the valve stem in the valve body will sometimes solidify with the liquid in the valve body, causing the valve to be unable to be used normally. For this type of problem, the staff basically wraps the valve with cotton cloth in advance, which is very inconvenient. Utility Model Content
