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:Why do the stem and the valve use movable connections?

1., the valve and valve body hole seal, you can customize the center

Q:Hello, the valve material is 3Gr13, stem 3Gr12, I would like to ask, this valve against sulfur?

it is easy to be corroded, the best use of dual phase steel, 20 alloy steel, alloy steel and zirconium C276 wood, but also to see the specific medium containing exactly what, these materials should be the cheapest dual phase steel

Q:What brand is good for fishing stem?

Valve brand is not very important, wheels should match better, the length is usually 1.8 meters or 2.1 meters. Valve stem should be noted that poles can not be too soft, in the reservoir, select rod pin slightly hard stem.A raft is a fishing rod on a fishing raft.

Q:How is the diameter of the valve stem determined?

In the valve manufacturing and production process standards, valve type, valve torque and valve stem diameter has a direct link.AskCan you say something about it, for example, the regulating valve?.Chasing the answerASME related standards, as well as GB GB standards relating to valve manufacturing.

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: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:The difference between the stem road and pole rock fishing rod sea rods what are the different points for these kinds of fishing pole in what place can exchange with the stem than to listen to people say that most of the soft road and pole soft also explain

Raft rod, road and pole, rock fishing rod and sea rod are fishing rod reel with use but are essentially different:1, raft rod in the four kinds of fishing rod is the shortest, capable, common length of 1.2 meters, -3 meters. Uses in the boat, raft or fish caught on small fish.2, Asia pole is a special bait Diaofa fishing rod, fishing fish will be distinguished according to a lot of hardness, but the length of 1.5 meters -4 meters. The utility model has the advantages that the bait is convenient to be thrown, and the false bait is more vivid with various operation techniques.3, Los Angeles rod was fishing in the rocky coast fishing rod, is a relatively good light operation. Length of more than 3.6 meters, about -7.2 meters. Hardness is common in size 1-5, depending on the size of the species.In particular, 4 sea rods cast rods, bait cast like distant fishing rod, is characterized by outstanding hardness and strong. Length of more than 1.2 meters, about -6.3 meters. Hardness is commonly found in size 20-85, depending on the range and distance of the cast.

Q:Pipeline ball valve in the valve stem generally choose what material?

Stem material for line ball valves:Anti sulfur ball valve for floating ball valveChinese GB 1Cr13 1Cr18Ni9The United States ASTM A276-410 A276-321

Q:How does the positioner output change when the feedback lever of the positioner and valve stem falls off?

The positioner and the control valve are connected with the feedback rod to fall off, and the positioner has no feedback and becomes a pneumatic amplifier with high magnification. If the positioner is positive, that is, the signal increases, the output also increases, then the stem fell off, the output run the maximum, and if it is counterproductive, then run zero.
