Q: Beijing exhibition, understand that Hauck can equipment, our existing batch valve stem need to be handled, I wonder if their home equipment use effect?: and the service is also very timely, good service attitude, our company is planning to buy a.

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: If the valve stem in the 50% position of the whole trip, then the flow through the valve is also in the most large 50%?: Look at what the spool is, there are a variety of curve relations, look at the equipment demand flow, and work methods.

Q: When the butterfly valve is installed, can the stem be downward? What are the criteria?: The valve stem can be installed vertically or horizontally, but the drive should be on top of the vertical installation. The stem should be downward and it is prone to accidents. This doesn't need any standard. It's the installation notes.

Q: The ball valve in the valve is in what state is open: The valve in the factory depends on the order of the switch before the core and the orientation of the handle, the valve is most clockwise, counterclockwise is open.

Q: What are their respective advantages and disadvantages?: Valve advantages:1, small flow resistance. Inside the valve body, the medium passage is straight through, the medium flows in a straight line, and the flow resistance is small.2, when opening and closing more effort. In comparison with the cut-off valve, the gate movement direction is perpendicular to the direction of the flow of the medium whether it is open or closed.3, high height, long opening and closing time. The opening and closing stroke of the ram is larger, and the reduction is done by screw.4, the media can flow in any direction on both sides, easy to install. Gate valves are symmetrical on both sides of the channel.5. Compact structure, good rigidity of valve, smooth channel, small flow resistance, stainless steel and carbide alloy used in sealing surface, long service life, PTFE packing, reliable sealing, easy and flexible operation

Q: What is the seal between the valve stem and the valve cover?: Most valves:The seal between the valve and valve cover depends on the valve cover gasket.The seal between the valve and the stem depends on the packing.There are also valves, valves and stem seal between bellows, "O" ring, and so on.

Q: The stem is suitable for what kind of fishing: A raft is a fishing rod on a fishing raft. Now also used for freshwater fishing, fishing line can be equipped with the stroke of fish, can also be cast, can be said to be the size of the weapon system.Raft rods are usually two sections, most of which are rods, and some of them are vibrating out, but very few.

Q: When the valve is installed on the horizontal pipe, the ball valve, valve stem, globe valve stem, butterfly valve stem and other direction can go down? People stand under the action. Higher pipe: To the first party to do, or as requested, the handle is not down, easy to pass the acceptance. Operation is inconvenient, can add chain wheel or add operation platform.

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.
