- Q:What exactly is the stem nut, please
- The stem nut has a certain strength and resistance to pressure, because the stem nut is the valve running process, the stem shaft strength directly to the stem nut. The stem nut and stem are rotated with the thread, and the friction coefficient of the stem nut is smaller.
- Q:Good or good red earthworm fishing rod
- Red with no barbed hooks, and not save, a few days will be a large number of deaths, occasionally when working with earthworms is also good.
- Q:Is the strength of the ball valve stem and torque the same?
- Depends on what the valve, but also depends on your torque is, how much pressure medium.
- Q:What is suitable for fishing rod
- I have to play with the stem and black turtle. The effect can also make 3 blackfish yesterday
- Q:What is the difference between the upper valve stem bearings of the thrust bearings?
- Its force direction is not the same, the general bearings are radial force, and the thrust bearing is in the end direction of the force, the solid structure is not the same."And you ask" thrust bearings, upper stem bearings what is the difference? / / thrust bearing, stem bearing difference"
- Q:What is the dish yellow in the valve?
- It is mounted behind the seat and plays a key role in the thrust and closure of the valve seat.
- Q:Horizontal installed gate valve, stop valve stem should be in the first half of the range,
- For example, fire pump, water pipe, gate valve, to see this side to the horizontal 90 degrees, turn 90 degrees in the opposite direction
- Q:The stem hook use of lead weight
- Don't be conceited, brother! I am talking about the static water pond or reservoir, winter raft string hook fishing crucian carp, I fell 10 grams can play 30 meters away, 10 grams fall to taut line, completely no problem! 15 grams fall, I feel most called hand.
- Q:How is the hand (knob) of the hand operated ball valve connected to the valve stem?
- Normally, there is no such thing. Because it is easy to rust for a long time.Do not use valve repair (can not be removed)
- 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.
We have business of various commodities, development of valve parts, brand promotion and agency servicesMain products: valves, mechanical parts, carbon steel, alloy steel parts, castings, forgings, etc. Products are all exported.By virtue of the advantageous location, we have a well-established sales network. We will further widen the market at home and abroad, and provide high quality products and services for our customers.
