What is the valve chamber of a long-distance pipeline used for?
The full name is cut-off valve chamber, what do you think?
Each section of the long-distance pipeline should have a valve chamber that can close the valve in an emergency.
The valve chamber is divided into manual cut-off valve chamber and RTU cut-off valve chamber.
Under normal circumstances, how long should a valve chamber be installed in a long-distance pipeline?
The valve chambers in long-distance pipelines can be divided into two types according to their functions.: Block valve chamber and distribution valve chamber. According to the name, it can be seen that the cut-off valve chamber mainly has a cut-off function, and the distribution valve chamber not only has a cut-off function, but also has a distribution function. In other words, a branch line can be drawn from this. The valves used in the valve chambers of long-distance pipelines are generally gas-liquid linkage ball valves.
The setting distance of the valve chamber is determined according to the regional level. In the first-level area, it is no more than 32km, in the second-level area it is no more than 24km, in the third-level area it is no more than 16km, and in the fourth-level area it is no more than 8km.
Reply 7# redmoon520 Please tell me upstairs, where do you find the setting distance of the valve chamber? Are there any relevant regulations?
The valve chamber of the long-distance pipeline has emergency shut-off and oil and gas distribution functions. Our valve chamber currently uses the Cameroon gas-liquid linkage valve.
The setting distance of the valve chamber can refer to GB50251 and GB50369.
The setting distance of the valve chamber can refer to GB50251 and GB50253. The requirements for oil and gas transportation are different!
