How to recognize the model of the pneumatic joint, and how to choose the model of the pneumatic join

1. The detailed identification of the model of the pneumatic joint is as follows:

1. The models and specifications of pneumatic joints are different according to different countries, different brands and different manufacturers. Brands in European countries have international standards (mainly inches).

2. There are standards in Asia such as Japan, and the general model labeling of China's mainland, Taiwan, South Korea, etc. is basically the same. The joint identification methods of pneumatic components based on China's mainland, Taiwan and South Korea are summarized as follows.

3. The model can be divided into three parts: series code (with English capitalization**) + piping outer diameter (with two digits**) + joint thread (with two digits or thread directly**).

2. Examples: 1. For example: PC 10- 02, the meaning of this gas joint is:

PC Straight Terminal Fitting Series (PC = Direct Type, PL = L Right Angle Type, PST= T Type (Tee), PB, PD, PX, SL, PH, etc.) 10 Connecting Tubing Outer Diameter.

2. There can be =16, etc.) - separator 02 thread code (can have inch pipe thread: 01 = g1 8" thread.

G1 4" thread = G3 8" thread = G1 2" thread, M5 = M5 thread, M10x1 = M10x1 thread, etc.

4. Therefore, the PC 10-02 gas joint is: straight joint, one end is connected to the air pipe with outer diameter 10, and the other end is connected to the direct head of the G1 2" pipe thread.

There are many brands of air pipe joints for cylinders, and the models are different, depending on which brand you often use. I'll tell you how to buy it if you don't know the model or brand, that is, explain what style and important size you need to use.

If the nominal diameter of the screw of the tracheal joint is equal to or less than 5mm, it is a standard thread such as M5, M4, M3, etc.; M5 and above are PT pipe threads, and the accessories have PT models corresponding to the size of pipe threads and threads, such as 1 8, 1 4, 1 2 and so on.

The cylinder air pipe joint has a direct gas pipe, that is, it is straight; If there is a 90-degree trachea inserted, it is L-shaped; There are two intubated tubes at 180 degrees, the two tracheas are 90 degrees to the screw teeth, and the two tracheas are parallel, that is, T-shaped; There are two trachea, one is 90 degrees and the other is straight, which is called Y-shaped.

How much is the screw as long as you buy an air pipe joint for a cylinder? What model? Do I need to regulate the speed? How many tracheas are connected? Can you buy it?

The connecting trachea is also divided into straight, 90-degree elbow, T-type, Y-type, + sub-cross-way, etc., and the position of the connecting different trachea is clearly marked.

In the case of frequent purchases, it is recommended to ask the manufacturer for this selection manual.

You're going to have a very hard problem here, so I'm going to draw a picture for you and mark the dimensions. Moreover, there is no industry standard for domestic connectors, so the data given to you is also from the respective manufacturer, which may not be suitable for you. It is recommended that you ask for a sample from a well-known brand company, and then there is a detailed product size in it, of course I can help you with this.

Contact me and give you a sample.

1. According to the tracheal joint on your site, choose the corresponding internal or external tooth quick connection, and there are also trachea.

2. According to the shape of the gas wrench joint you bought, the gas pipe is distributed.

3. Generally, less than three-quarters are the same, internal teeth, external teeth, and trachea. The 1-inch cannon head is larger.

4. The air wrench (impact wrench), also known as the combination of ratchet wrench and power tool, is mainly a tool that provides high torque output with minimal consumption. It accelerates the rotation of an object with a certain mass through a continuous power source, and then instantly hits the output shaft, so that a relatively large torque output can be obtained.

5. Compressed air is the most common power source, but there are also electric or hydraulic ones, and the use of batteries has also been very popular in recent years.

6. Pneumatic wrenches are widely used in many industries, such as automobile repair, heavy equipment maintenance, product assembly (commonly called"Pulse tool"and high torque output required for precise torque output), major construction projects, installation of wire screw sleeves, and any other place.

The pneumatic joint you are referring to may not be the air intake joint upstairs, but the sleeve specification of the square head front sleeve, which depends on how big the hex nut you are playing, and the corresponding sleeve is selected, and the choice of the sleeve also depends on how big the square head of your wrench is, there are 8".

Type A, Type B, Type C, Type D, Type E, Type F, Type DC, Type DP.

Type A: One end is a circular arc joint stuck in the female connector, and the other end is a connecting thread with an internal thread.

Type B: One end is a groove with two tab male connectors, and one end is a threaded connection with a male thread.

Type C: Groove with two tab plugs at one end and a slub hose fitting at the other end.

Type D: One end is a groove with two male puller heads, and one end is a threaded connection with an internal thread.

Type E: One end is a circular coupling stuck in the female connector, and the other end is a hose fitting with a slub shape.

F-type: one end is a circular arc joint stuck in the female connector, and the other end is a threaded connection with a male thread.

DC type: It is a cap plug with a groove with two ear clamp male nipples, which can be snapped into the male arc.

DP type: It is an arc plug, also called an inner plug.

Fitting Model Selection:

Size: Nominal diameter of the hose, the type of connector (mainly flange connection, threaded connection, quick coupling connection) and the size of the metal hose, the length of the hose.

Pressure: According to the actual working pressure of the hose, check the nominal diameter and pressure gauge of the corrugated metal hose to decide whether to use the stainless steel mesh sleeve type of metal hose.

Medium: The chemical properties of the medium conveyed in the hose determine the material of each part of the hose according to the corrosion resistance of the hose material.

Temperature: the working temperature and range of the medium in the hose; The ambient temperature at which the hose is operating. At high temperature, the temperature correction coefficient of the working pressure of the metal hose at high temperature must be used to determine the correct pressure level.

The flange connecting the pneumatic joint should be the valve flange, and the normal applicable medium of the pneumatic joint can be bent around the ordinary water with a temperature of 0-60 vertical infiltration, and the special medium such as: oil, acid and alkali, high temperature and other corrosive and hard textures should be selected. When the flexible pneumatic joint is used at the inlet and outlet of the water pump, it should be located on the side of the water pump near the water pump, and a metal reducer joint should be installed between it and the water pump, and it should be installed at the large diameter of the reducer.

When the displacement of the pipeline is greater than the maximum compensation of the pneumatic joint, the number of pneumatic joints should be increased to parallel the displacement, and it is strictly forbidden to adjust the deviation of the pipeline, so that the pneumatic joint is in the ultimate state of disturbance displacement and deviation, and can not exceed the limit (expansion, displacement, deflection, etc.). For high-rise water supply or suspended water supply, the pipeline should be fixed on the hanger, bracket or anchor frame, and the joint should not be allowed to bear the weight of the pipeline itself and the axial force, otherwise the joint should be equipped with an anti-pull-off device.
