Q: The stem, cast rods, sea rods, rod from what is the difference?: It's nothing specialThat, generally refers to the use of the shore, so is more than 3.6 meters, and compared with other pole hard, because of the need to bring together lead to the seaSea rod is a generic, all applications can be said in the fishing rod as sea pole

Q: What exactly is the stem nut, please: Sometimes it is not possible to use copper alloy stem nuts for production and operation. Because some products or environment will corrode copper medium, the material of the stem nut can not be made of copper. On the basis of the electric valve, the stem nut has a melon clutch, which requires a certain amount of heat treatment to achieve more surface hardness and maximum hardness. When using the steel stem nut, we should pay attention to the thread, and the steel stem nut is easy to bite. But the stem nut is only suitable for low pressure and small bore valves. The strength of the stem nut of this material is less than that of the metal stem nut

Q: Clamp design of valve stem: Characteristic analysis and design of crankcase and hydraulic end of model jx219_BW-100 slurry pumpDesign of tooling for tailstock of jx220_A6140 latheDesign of lifter for jx221XY-4 core drilling machineOverall design of jx222ZL05 miniature wheel loaderModel jx223ZL15 wheel loaderJx223 universal material testing machine CADDesign of jx224 three coordinate NC grinding machine

Q: Sea poles, stem what is the difference between the general water reservoir play, 3 meters or so, what pole is better, please advise: The sea rod is rough and hard to throw. Raft thin, soft, good signal. The sea pole is better in summer, and the raft pole is better in winter. Of course, these are personal experiences, not others.

Q: Butterfly valve stem calculation, why not take into account the bending moment?: Now most of the one-way seal structure, the three eccentric moment has little effect, mainly consider the torsion stress, two-way sealing butterfly valve or non - moment sealing butterfly valve to take into account the stem interference.

Q: Can the stem be fishing with sequins or something like that?: The stem is first because the ship is not suitable for long shot rod, light bait, as compared to the road sub: straight shank rod wire ring is very big, very suitable for throwing light bait, but all is not what fishing rod can not be used, it will be necessary to use a little heavier sequins, iron that weight, try to be a fine line,

Q: Ball valve stem 90 degrees milling flat, how to process?: two disc milling cutter in parallel with the cutter shaft, the gap is flat milling thicknessOne piece is recommended upstairs, but vertical milling is the most convenient

Q: Stem deformation of valve stem: The reasons are as follows:(1) expansion;(2) closed

Q: How many connections are there between the handwheel and the stem?: I don't understand. I've got some information for youThe simplest is: your home faucet is the valve.First, the definition of valve:"Valve" is defined in the fluid system, used to control the direction of the fluid, pressure, flow device. A valve is a device for flowing or stopping the medium (liquid, gas, powder) in a pipe and equipment and controlling its flow.Two, according to the role of opening and closing valves, valve classification methods are many, here describes the following.1. classification by function and use(1) cut-off valve: cut off valve, also known as closed circuit valve, whose role is to connect or cut off the pipeline medium. The cut-off valve includes gate valve, globe valve, plug valve, ball valve, butterfly valve and diaphragm.(2) check valve: check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline. Pump water off the bottom valve check valve also belongs to class.(3) safety valve: the role of the safety valve is to prevent the pipe or device in the medium pressure exceeds the required value, so as to achieve the purpose of safety protection.(4): regulating valve regulating valves including control valve, throttle valve and pressure relief valve, and its role in the regulation of the medium pressure, flow parameter.(5) shunt valve: diverter valve, including a variety of distribution valves and traps, etc., its role is to distribute, separate or mix the medium in the pipeline.

Q: Shandong 30 loader multiple valve stem card what's wrong.: You take the two main stem carefully removed, check the stem and valve bore cavity whether there is scratch, if there is a local scratch, it may be dirty stuck in it, and then pull the stem when it pulled. Scratches if deep, leakage will be large, repair will feel bucket slow, little force and so on. All components should be removed before washing, especially the safety valve. After the demolition, the whole body with kerosene cleaning, safety valve pressure should not be adjusted, or there is no test stand, you do not know the specific pressure is how big.
