The technical requirements of the valve well, the size of the valve well

Applicable medium: mining, steel industry - used for coal slurry, filter slurry, etc. Purification units – for wastewater, slurry, dirt and clarified water with suspended solids.

Paper industry – for pulp, material and water mixtures of any concentration. Sugar industry – for sugar beet washing, syrup, juice, juice, etc. Food industry – for washing and washing equipment, grain conveying equipment, mash, etc.

Power station ash removal - for ash slurry Wuhu Naide Hose Valve Industry, founded in 1998, is a high-tech enterprise integrating R&D, production, sales and service, combining production, education and research. At the same time, it has a complete product testing center, all kinds of production equipment, and perfect inspection facilities. **：

Because the valve well is the hub of the pipeline, it has the following requirements of its own:

1: The valve well itself cannot seep water, and its sealing must be ensured;

2: In the process of using the water supply pipeline, the pipeline will be subjected to pressure from different aspects, which will produce different degrees of jitter or settlement, that is, the connection between the water supply pipeline and the valve well is required to be reliable, and it can adapt to a certain degree of shaking and settlement, and will not make the water infiltrate into the well chamber; When the pipeline of the valve well buried deep is slightly larger, cast iron valves (such as globe valves, butterfly valves, etc.) are generally used, and the cast iron valves are soaked in water for a long time, which will affect their service life or cause fractures, so the requirements for tightness are higher;

3: The connection between the valve well bore and the well body and the manhole cover should be reliable, and the water should not seep into the well chamber because of heavy rain or stagnant water.

4: The valve well is buried underground, which must withstand different pressures from all directions, and corrosion and infringement of different chemicals, and requires its pressure bearing capacity and acid and alkali corrosion resistance to be good.

Each valve well is more than the valve left and right plus 50cm, the height according to the requirements of the drawing, buried can be reduced.

There is an atlas that can be checked, see 02S515 drainage inspection well for details.

There should be a size indication on the drawing. You look carefully for hawa. on the outdoor floor plan. Generally, there is a number next to the shaft. There is no direct indication of the specifications of the well.

You look at the various valve form factors. Each type of valve has a different shape and size.

Dear, Wu shouts rotten hello! We'll be happy to answer for you. Water supply pipeline valve well setting requirements A:

Hello dear dear, the valve position can be combined with the node setting of the connecting pipe and the important water supply branch pipe, and the valve spacing on the main pipe is generally 500-1000m. 2. Generally, the valve on the main pipe is located downstream of the connecting pipe, and the impact on the branch pipe is minimized when the valve is closed by cavity leakage. 3. At the connection between the branch pipe and the main pipe, a valve is generally set on the branch pipe so that the maintenance of the branch pipe does not affect the water supply of the main pipe.

4. Set up a valve before the fire hydrant. 5. The arrangement of the valves on the branch pipe: a maximum of 5 fire hydrants between the two valves is appropriate, and the maximum interval between the two fire hydrants is 120m, that is to say, there is no lead seepage more than 500m, and another valve must be set up Thank you for your patience.

The above is my full reply, if you are satisfied with my service, please give a thumbs up, and I wish you all the best! Peace and joy!

Inspection well management of the first article in order to strengthen the maintenance and management of urban road underground inspection wells, to ensure smooth traffic and personal safety, according to the "urban road management regulations" and "Liaoning Provincial Municipal Public Facilities Protection Regulations" and other relevant provisions, combined with the actual situation of the city, these provisions are formulated. Article 2 These provisions apply to the management and maintenance of underground inspection wells attached to urban roads within the urban planning area of the city. The underground inspection wells mentioned in these regulations refer to the inspection wells, valve wells, rain and sewage drainage wells, fire hydrants and other manhole covers, grates and ancillary facilities of electricity, gas, heating, water supply, drainage, fire protection, communications, traffic signals, lighting, cable television and other underground facilities buried in urban roads.

Third Municipal Urban and Rural Planning and Construction Commission is the administrative department of municipal facilities, responsible for the comprehensive coordination and management of urban road underground inspection wells, and organize the implementation of these provisions; Its subordinate municipal facilities management agency, Yun Demolition Tsai, is responsible for the daily management of underground inspection wells in the central urban area. The municipal facilities management department of Nanfen District and Benxi High-tech Zone is responsible for the daily management of underground inspection wells in their respective jurisdictions.

The valve well is a pit (or well) similar to a small room is set up for the valves of underground pipelines and underground pipelines (such as tap water, oil, natural gas pipelines, etc.) in order to facilitate the operation or maintenance of part of the pipeline network when it is necessary to open and close part of the pipe network, and the valves are installed and arranged in this pit to facilitate regular inspection, cleaning and dredging of pipelines and prevent pipeline blockage. This pit is called a valve well. There must be valves in a valve well, but there is not necessarily a valve well if there is a valve.
