Introduction to the selection and installation of pipeline valves, what are the general requirements

About pipeline valves.

Mainly in factories are most common, in addition to furniture in our lives.

Natural gas. It is not difficult to see pipeline valves on pipes such as water. We know that the use of valves in pipelines is directly related to the safety of gas and water, so we need to take it seriously at all times.

For such a device, even if the small mistake, the pipeline valve may have a dangerous accident, it can be seen that the small valve, the correct management and use can achieve our greatest hope. So, in order to better let friends understand the pipeline valve, the following is an introduction to the selection and installation of pipeline valves.

Pipeline valve selection:

1. The selected pipeline valve needs to be controlled by professionals.

2. It is necessary to select the pipeline valve correctly according to different pipeline requirements, such as whether the working pressure is strong, whether the temperature needs to be adjusted, and how much the performance demand is.

3. To select pipeline valves, it is necessary to have a clear understanding of the nature of the fluid characteristics in the pipeline, such as discharge capacity, sealing level and other factors.

4. The size and size requirements of the pipeline valve include diameter, connection size, weight bearing, modeling, etc.

5. It is necessary to understand the performance of pipeline valve related products, and understand the reliability, service life and other performance of the pipeline valve required.

Pipeline valve installation:

1. Before installing the pipeline valve, the installer needs to carefully check the signs on the pipeline valve, the installation manual, etc., so as to ensure the safety and correctness of the installation. In addition, the installation of pipeline valves requires cleaning the inside of the installation, mainly to reduce the blockage of the valves.

2. As the key button of the pipeline, the valve needs to be installed in a place with a relatively large space, and the transmission device needs to be connected and then installed upright on the pipeline valve, so that the valve can be operated and inspected in a timely and convenient manner.

3. When the valve is installed, the installer needs to follow the direction of the medium flow as the installation direction. The purpose of this is to ensure that the flow direction of the medium is consistent with the direction of the valve.

4. For the parts of the link valve of the pipeline, the installation of the pipeline valve should be in the diagonal direction, and then the pipeline valve should be tightened, and it should not be tightened at one time.

5. According to the arrow indication of the pipeline valve and the closing indication, rotate the valve into place, and the installation is completed.

The above is the relevant information about the selection and installation of pipeline valves, the selection of pipeline valves is related to whether the device can be used and worked for a long time, and the installation of pipeline valves is directly related to the safety of pipeline valves. Although we have done a good job of equipment safety measures, we still need to be very careful in the use of pipeline valves. Hopefully, the above information can help you.

As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

The valve should be located in a place that is easy to call, easy to operate, and maintain. Valves on rows of pipes (e.g., pipes entering and exiting devices) should be arranged centrally, and consideration should be given to setting up operating platforms and ladders. The valves on the tung chain jujube of the pipeline are arranged in parallel, and the center line should be as complete as possible.

The net distance between the handwheels should not be less than 10qmm, in order to reduce the pipeline spacing, the valves can be staggered and disassembled;

In many ways, sealed. Level, the total sale of a time and a half will not be clear, to give you a website, inside the news column has a detailed explanation of the valve in the cavity Chang installation instructions. There is a control valve. Gate valve round liquid. Butterfly valves. Ball valves and so on,

Your question is too broad! Many valves have their own auspicious installation requirements! If you want to know, Brother Shen can find a wide banquet to attack me! Shanghai Anti-corrosion Valve Group **** Jin Liqiang will answer for you, and contact me if you have any questions!

1. The first bai first proofreads whether the valve model is consistent with the working conditions, and pays attention to the connection size and medium flow direction to ensure the consistency with the special requirements of the valve;

2. It is necessary to carefully check the inner cavity and sealing surface of the valve, and it is strictly forbidden to have dirt or sand particles attached;

3. Before installing the valve, be sure to reserve the necessary space for valve drive;

4. The valve must be installed vertically and cannot be reversed;

5. During installation, the valve disc should stop at the closed position;

6. Tighten the bolts of each connection part evenly to avoid loosening;

7. Carefully inspect the packing part, and ensure the sealing of the packing while also ensuring the flexible opening of the ram;

8. It should be installed according to the installation instructions of the manufacturer, and a firm foundation should be set for valves with large weight.

The nodes of the outdoor ring pipe network of the residential area should be set up according to the separation requirements. When the annular pipe section is too long, it is advisable to set up a segmented valve.

Principles for the selection of valves used on water supply pipes:

1. When the pipe diameter is not more than 50mm, it is advisable to use the stop valve, and when the pipe diameter is greater than 50mm, the gate valve and butterfly valve should be used.

2. When it is necessary to adjust the flow rate and water pressure, it is advisable to use the regulating valve and the shut-off valve.

3. For parts that require low water flow resistance (such as on the suction pipe of the water pump), the gate valve should be used.

4. Gate valves and butterfly valves should be used on the pipe section where the water flow needs to flow in both directions, and no stop valves should be used.

5. Butterfly valves and ball valves should be used in parts with small installation space.

There are two types of valves that need to be installed in the home improvement pipeline.

What is the installation standard of fire pump valves?

Generally, considering the convenience of maintenance, it is necessary to install a control valve before entering the interface and before the water outlet.

1.At the entrance to the building 2On the ground floor riser of the building 3A valve is installed in front of the water meter of each household.

It mainly considers the convenience of maintenance and overhaul, and the needs of functions in the operation of the project.

1. Where convenient control is required. 2. A place that is convenient for maintenance. 3., inlet end, outlet end.

Valves are installed in the water supply pipes at the following locations:

1. Introducing it into the pipe section;

2. The nodes of the outdoor annular pipe network of the residential area should be set up according to the separation requirements;

3. The starting end of the branch pipe or the starting end of the intervention pipe connected from the main water supply pipe of the residential area;

4. The beginning of the water distribution pipe connected from the water supply pipe in front of the household pipe, water meter and the indoor water supply pipe of each branch riser to the household and public toilet;

5. When there are 3 or more water distribution points on the water distribution branch, it should be set;

6. Pools, water tanks, pressurized pump rooms, heaters, pressure reducing valves, pipeline backflow preventers, etc.

The valve (famen) is a control component in the fluid transfer system, which has 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. According to the material, the valve is also divided into cast iron valves, cast steel valves, stainless steel valves, etc.), chromium-molybdenum steel valves, chromium-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard customized and other valve materials.
