Parameters
description
Carbon steel, stainless steel, 316L. Working pressure: PN10/PN16CLASS150, working temperature 20°C-425°C. Valve diameter DN25-DN300. Connection: flange. Transmission: manual, pneumatic. Applicable media: oil, acid, corrosive medium, etc. Manufacturing standard national standard. The upward discharge valve is mainly used for bottom discharge, discharge, sampling and non-dead zone shut-off operations of reactors, storage tanks and other containers. With the help of the bottom flange of the valve door welded to the bottom of the storage tank and other containers, so as to eliminate the need for the actual situation of the residual home and discharge valve root of the process medium usually at the outlet of the container, the bottom structure is designed to be flat bottom type, the valve body is V-type, and the valve disc is provided with two working modes of lifting and lowering. The valve body cavity has a washout-resistant, corrosion-resistant sealing ring. At the moment of opening the valve, it can protect the valve body from breaking the medium erosion and corrosion, and carry out special treatment on the sealing ring, so that the surface hardness reaches HRC5-62, with high wear resistance and corrosion resistance. At the same time, the design of the short-stroke disc is adopted.
Material selection:
W C B / A 1 0 5 / 1 6 M n Mainly suitable for non-corrosive media. Such as oil, gas, water, powder, etc.
C F 8 / C F 3 / 3 0 4 / 3 0 4 L is mainly suitable for nitric acid and purified terephthalic acid.
C F 8 m / C F 3 m / 3 1 6 / 3 1 6 L is mainly suitable for acetic acid and purified terephthalic acid.
Nickel-based alloys and titanium alloys are mainly suitable for purified terephthalic acid and strong corrosive media.
The specific choice of material should be determined according to the actual use of the medium.
Pressure and temperature class
A S M E B1 6 . 3 4 specifies the pressure and temperature grades of various materials of A S T M, which specifies in detail the various pressure levels, and the maximum allowable non-impact pressure (gauge pressure) of different housing materials at various operating temperatures, which is one of the main benchmarks for the design and selection of valves. Therefore, the selection of the discharge valve must be determined by the operating pressure and operating temperature according to the pressure temperature level AS M E B 1 6 . 3 4 to determine the material (referring to the housing) and pressure level (referring to the nominal pressure) of the selected discharge valve. If the operating temperature and pressure are overloaded, the valve may be damaged. When selecting valves, various working conditions should be fully considered to avoid overload operation of valves.
