Q:When the butterfly valve is installed, can the stem be downward? What are the criteria?
Not only can the transmission device at or above the level of 90 degrees, the transmission device is not allowed to download is in the valve below, it's too dangerous. This does not require any standard.
Q:The parts of the valve do not understand
Are the two forks of the cutaway section? That's flat.
Q:Why do the stem and the valve use movable connections?
Stem and disc material is different, can not be made as a whole. Second, it may also be related to the way it is installed.
Q:On the butterfly valve, the stem has single axis, no pin and double shaft without pin.
In the soft sealing butterfly valve, no pin valve shaft, there are two main ways of connection: 1, through the shaft without pin, 2, double shaft without pin, through the shaft without pin, in the design is the most basic method, design simple. When the shaft is machined, the double half shaft has a certain degree of difficulty in making it.
Q:Stem material
3, alloy steelGenerally choose 40Cr, 38CrMoA1A, 20CrMo1V1A and other materials. 40Cr after chrome treatment, apply to nominal pressure is less than 32MPa, temperature less than 450 degrees of water, steam, oil and other media. 38CrMoA1A after nitriding treatment, can work temperature of 540 degrees under the pressure of 10MPa, often used in power plant valve. 20CrMo1V1A after nitriding treatment, can work at 570 degrees temperature under the pressure of 14MPa, often used in power plants valve.4,Generally choose 2Cr13, 3Cr13, 1Cr17Ni2, 1Cr18Ni12Mo2Ti and other materials. 2Cr13, 3Cr13 stainless steel for nominal pressure less than 32MPa, the temperature is less than or equal to 450 degrees of water, steam and weak corrosive medium, can be chromium plating, high frequency hardening and other methods to strengthen the surface. 1Cr17Ni2 stainless steel valves and cryogenic valves are resistant to corrosive media. 1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti stainless acid resistant steel for nominal pressure less than 6.4MPa, temperature is less than or equal to 600 degrees of high temperature valve, can also be used for temperature less than -100 degrees of stainless steel valve, low temperature valve. 1Cr18Ni9Ti can resist corrosive medium such as nitric acid; 1Cr18Ni12Mo2Ti can resist corrosive medium such as acetic acid. When 1Cr18Ni9Ti and 1Cr18Ni12Mo2Ti are used in high temperature valves, nitriding treatment can be adopted to improve the scratch resistance.
Q:Chlorine valve, valve stem, valve spool are selected what material is better?
In fact, ordinary carbon steel, but chlorine special valve sealing better, specific you can ask about the production of chlorine valve manufacturers, chlorine, many things are national standard parts, very good buy
Q:How is the sphere of the Solidworks ball valve fitted with the stem or valve body or valve seat?
Create a new assembly drawing and import parts. Choose the ball and ball valve in contact with the two sides, with the panel in the election tangent to it.
Q:How to use a dial indicator measuring stem bending
(5) by measuring and recording the dial indicator. According to the records, the rocking value of the shaft in the same section is calculated, and the 1/2 value is taken as the bending value of each section.(6) the bending value of the same azimuth of each section along the axis length is traced in the rectangular coordinate with the trace point method. According to the measured bending value and connected to the bitmap, there are two straight lines, and the intersection point of the two lines is the maximum bending point of the axis
Q:About butterfly valve plate and valve stem connection
But the taper pin needs to be loosened, or there will be a risk of natural shedding!
Q:The stem, cast rods, sea rods, rod from what is the difference?
There are also ships, poles, rods and so on, you can search the picture to see the corresponding pole will understand
