The valve is a pipe accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters of the conveying medium (temperature, pressure and flow). According to the function, it can be divided into Gate Valve , Globe Valve,Check Valve, Ball Valve ,Butterfly Valve, control valve and so on.
The valve is the control part in the fluid conveying system, which has the functions of cut-off, regulating, diversion, preventing countercurrent, stabilizing pressure, shunting or overflow pressure relief. Valves are used for fluid control systems, ranging from the simplest cut-off valves to the most complex automatic control systems, have various varieties and specifications.
Valves can be used to control all kinds of fluids such as air, water, steam, corrosive media, mud, oil, liquid metal and radioactive medium. The valve is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, valves and other non-standard custom according to the material .

Recently, the Swedish company Chris has introduced a new two-stroke diesel engine cylinder diameter measuring instrument. It is understood that the new cylinder diameter measuring instrument consists of a measuring device and a wireless hand-held terminal. The measured data will be transmitted via the radio communication line to the antenna inserted into the starting air valve sleeve. The stored data will be passed to the computer's Excel application via Bluetooth, USB or SD card.
It is reported that the introduction of the new cylinder diameter measuring instrument is mainly to satisfy the user to quickly ascertain the internal state of the cylinder liner of the two-stroke diesel engine. The new cylinder diameter measurement instrument can be used without removing the cylinder head or the exhaust valve housing. The condition of the cylinder block is measured. The new liner diameter measuring instrument replaces the inner diameter micrometer and can be inserted into the cylinder liner through the scavenging port. Measuring the cylinder liner with the new cylinder liner diameter measuring instrument takes only a fraction of the time required for the traditional measurement methods previously used. When measuring the diameter of a cylinder block using a conventional cylinder diameter meter, it takes not only several hours to remove (and install) the cylinder head, but also the risk of failure due to reassembly. At the same time, the new cylinder liner diameter gauge can presume diesel data for most existing two-stroke diesel engines. With a weight of only 3.6 kg, it is suitable for measuring 500 to 980 mm diesel engine cylinder bores.
The radio transmitter of the new cylinder block diameter meter has the CE mark required by the EU and Turkey. Chris Marine Company stated that in order to verify whether the new cylinder block diameter meter meets the standards of other countries, the most important standards are the United States, Japan, China and South Korea, and further tests will be conducted.
Extensive reading:
The basic structure of the cylinder block engine is an important part of the engine block group. Between the cylinder head and the oil pan, strictly speaking, this part should be called the cylinder block-crankcase! Because the upper part is one or several cylinders, the lower part is the crankcase supporting the crankshaft! These two parts are generally cast together, we usually referred to as cylinder block!
