What is the meaning of valve Z41T-16C+DN200.

What is the meaning of valve Z41T-16C+DN200 pro! Hello, happy to answer your <>

The meaning of pro-valve Z41T-16C+DN200 is as follows: Z represents gate valve, 4 represents flange connection, 1 represents open rod, and T means that the gate valve plate is copper core. 16 represents the nominal pressure of the valve, and the selected material of the valve body.

Therefore, the Z41T gate valve represents the open rod flange gate valve, usually only the gate plate of the cast iron gate valve is a copper core, so it is an open rod flange cast iron gate valve. Z41HT-16C gate valve is a single gate valve, the gate rises and opens, and the gate falls and closes, which can be used as a general valve for pipeline switching. A valve is a pipeline attachment used to open and close pipelines, control the flow direction, regulate and control the parameters (temperature, pressure and flow rate) of the conveyed medium.

According to its function, it can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transportation systems, which have the functions of shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves for fluid control systems range from the simplest shut-off valves to the most complex valves used in automated control systems.

Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurries, oils, liquid metals and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, etc.), chrome-molybdenum steel valves, chrome-molybdenum vanadium steel valves, duplex steel valves, plastic valves, non-standard customized valves, etc. Hope mine can help you <>

Gate valve is one of the most common opening and closing valves, which uses a gate (i.e., an opening and closing piece, in which the opening and closing part is called a gate or gate, and the gate seat is called a gate seat) to connect (fully open) or cut off (fully closed) the medium in the pipeline. It is not allowed to be used as a shut-off, and the ram should be avoided in use, because the erosion of the high-speed flowing medium will accelerate the damage of the sealing surface. The Shuangde gate plate is perpendicular to the one-sided side of the channel centerline of the gate seat as a lifting movement, cutting off the medium in the pipeline like a gate, so it is called a gate valve.

According to the description of the preparation method of the valve model, it can be known:

Z45T-16(L) is the gate valve model, DN200 is the gate valve diameter. Where:

Z represents the gate valve, 4 represents the flange connection, 5 represents the dark rod structure, T represents the sealing surface material is copper, 16 represents the nominal pressure is 16 according to, and the last L represents the gate valve is the medium thread buckle structure. As shown below:

DN100 refers to the inner diameter of the butterfly valve.

d stands for. It is the butterfly valve 3 that represents the turbine drive.

4 represents the flange connection.

1 stands for straight-through.

X stands for butadiene rubber seal.

10 represents the pressure in kilograms).

Butterfly valve (English: butterfly valve) refers to a kind of valve with a shut-off part (disc or butterfly plate) as a disc, rotating around the valve shaft to achieve opening and closing, which is mainly used for cutting off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjusting.

The butterfly valve is usually less than 90° when fully open to fully closed, and the butterfly valve and the butterfly rod itself do not have the ability to self-lock, so in order to position the butterfly plate, a worm gear reducer should be installed on the valve stem. The use of worm gear reducer can not only make the butterfly plate have the ability to lock itself, make the butterfly plate stop in any position, but also improve the operation performance of the valve.

The characteristics of the industrial butterfly valve can withstand high temperatures, the applicable pressure range is also high, the valve nominal diameter is large, the valve body is made of carbon steel, and the sealing ring of the valve plate is made of metal ring instead of rubber ring. The large high-temperature butterfly valve is made of steel plate welding, which is mainly used for flue air ducts and gas pipelines of high-temperature medium.

The relationship between the opening of a butterfly valve and the flow rate is basically linear and proportional. If it is used to control the flow rate, its flow characteristics are also closely related to the flow resistance of the piping, such as the diameter and form of the valves installed in the two pipelines are the same, and the pipeline loss coefficient is different, the flow rate of the valve will be very different.

If the valve is in a state of large throttling, the back of the valve plate is prone to cavitation, and there is a possibility of damaging the valve, so it is generally used outside 15°.

When the butterfly valve is in the middle opening, the opening shape formed by the valve body and the front end of the butterfly plate is centered on the valve shaft, and the two sides form different states, the front end of the butterfly plate on one side moves along the direction of flowing water, and the other side moves against the direction of flowing water, therefore, the valve body on one side and the valve plate form a nozzle-shaped opening, and the other side is similar to the throttle hole-shaped opening, the nozzle side is much faster than the flow rate on the throttle side, and negative pressure will be generated under the valve on the throttle side, and the rubber seal will often fall off.

The operating torque of the butterfly valve, due to the different opening and opening and closing direction of the valve, its value is different, and the horizontal butterfly valve, especially the large-diameter valve, due to the water depth, the torque generated by the difference between the upper and lower head of the valve shaft can not be ignored. In addition, when an elbow is installed on the inlet side of the valve, a deflection flow is formed, and the torque increases. When the valve is in the middle opening, the operating mechanism needs to be self-locking due to the action of the water flow torque.
