Advantages and disadvantages of various valves (5)
5, plug valve: refers to the closing parts into a plunger shaped rotary valve, through 90° rotation to make the valve plug on the channel opening and valve body opening or separate, to open or close a valve. Plug can be cylindrical or conical in shape. Its principle is basically similar to ball ...Read more -
Advantages and disadvantages of various valves (4)
4, globe valve: refers to the closing parts (disc) along the center line of the valve seat movement. According to the moving form of the disc, the change of the valve seat opening is directly proportional to the disc stroke. Due to this kind of valve stem open or close stroke is relatively short...Read more -
Advantages and disadvantages of various valves (3)
3, ball valve: is evolved from the plug valve, its opening and closing parts is a ball, using the ball around the stem axis rotation 90° to realize the purpose of opening and closing. Ball valve is mainly used to cut off, distribute and change the direction of medium flow in the pipeline. The ba...Read more -
Advantages and disadvantages of various valves (2)
2, butterfly valve: butterfly valve is a disc type opening and closing parts reciprocating 90° or so to open, close and adjust the fluid channel of a valve. Advantages: (1) Simple structure, small volume, light weight, consumption materials, not used in large caliber valves; (2) fast opening and...Read more -
Advantages and disadvantages of various valves (1)
1. Gate valve: Gate valve refers to the valve with the closing part (gate) moving along the vertical direction of the channel axis. It is mainly used as the cutting medium in the pipeline, that is, fully open or fully closed. In general, gate valves should not be used to regulate flow. It can b...Read more -
What are the features of plug valves?（1）
What are the features of plug valves? 1, the valve body of the plug valve is integrated, top-mounted design, simple structure, convenient online maintenance, no valve leakage point, support higher pipeline system strength. 2, the medium in the chemical process has a strong corrosive, in the chem...Read more -
What is a plug valve ？
What is a plug valve ？ Plug valve is a fast switch through valve, due to the movement between the sealing surface with wipe effect, and in full open can completely prevent contact with the flow medium, so it can also be used in the medium with suspended particles. Another important feature of p...Read more -
Butterfly valve standard overview and structural applications
Butterfly valve standard overview and structural applications New product structure of high performance butterfly valve seat design, according to the direction of the pressure source, automatically adjust seat, achieve the effect of double valve with pressure, and increase the service life of...Read more -
Butterfly valve principle features
It is especially suitable for the butterfly plate of large-caliber valve to be installed in the diameter direction of pipeline. In the butterfly valve body cylindrical channel, disc disc around the axis of rotation, rotation Angle between 0°~90°, rotation to 90°, the valve is fully open stat...Read more -
Function principle of check valve
Check valve is also known as reverse flow valve, check valve, back pressure valve and one-way valve. These valves are automatically opened and closed by the flow of the medium itself in the pipeline, belonging to an automatic valve. Used in pipeline system, its main function is to prevent ...Read more -
Double disc check valve compared with swing check valve advantages
A. Check valve structure, small size, light weight, for valve installation, handling, storage and pipeline layout bring great convenience, and can save costs. B. Reduced line vibration. In order to reduce line vibration to a minimum or eliminate line vibration, shut down as soon as possibl...Read more -
Forged steel globe valve advantages
Forged steel globe valve advantages: The most obvious advantage is that in the process of opening and closing, because the friction between the disc and the valve body sealing surface is less than the gate valve, so wear resistance. The opening height is generally only 1/4 of the diameter o...Read more
