About calculation of the pressure regulators at designing of city gas distribution networks

A.R. Ragimov

In the article the analysis of various methods of calculation of the pressure regulators is made at designing city gas distribution networks. The carried out analysis has shown, that existing methods of calculation have some lacks. First it speaks that depending on an arrangement of floor spaces on the general plan and the chosen circuit of gasification the radius of action of pressure regulators can vary essentially. Second cities and settlements with close volumes of gas consumption depending on density of building and number of floors can considerably differ in the extent of a gas network. Proceeding from the aforesaid, the expediency of carrying out of calculation of optimum number of regulators is proved on the basis of minimization of multiplication of expenses for metal and capital investments on construction of gas distribution networks. On the basis of the data on gasification of some cities and settlements of republic curves for calculation of optimum number of regulators have been constructed. Results of researches can be used at construction and reconstruction of gas distribution networks of cities and settlements of republic.
