Q: How to set the valve stem diameter: Check the standard, there will be the corresponding pressure, diameter of the smallest diameter of the stem, such as gate valve is GB/T12234-2005, sorry ah, I do not have information on the ball valve, you go to check

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: Why do the stem and the valve use movable connections?: 1., the valve and valve body hole seal, you can customize the center

Q: What's the difference? Will it break? If the technology is good, will it be broken with the stem? I haven't opened the valve yet. Can I catch it in the daytime with the string hook? I used the bells!! Ask God for us!!: This is not played, dare not assert! Downstairs continue! : handshake

Q: Hydraulic excavator main control valve stem wear can be changed? Will the valve bore not be worn?: It is recommended to change the set because the rod is worn out and the valve body should be worn almost as well. Change the set for safety. One is to reduce environmental pollution, the valve core and valve sleeve wear off, the gap is also large, began to leak oil.

Q: Where exactly is the stem seal on top of the ice cream machine?: The ice cream ring of a single ice cream machine usually has two, and the ice cream ring of the three ice cream machine usually has 8.

Q: River fishing rod or sea pole?: I think night fishing, I personally prefer raft, multi-point, easy to operate, but the tonality is slightly hard

Q: What about the water leakage at the valve stem of the sanitary manual stainless steel butterfly valve?: 2, the big diameter can be purchased by the corresponding specifications of the sealing ring replacement.

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: 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.
