Special buried valve well for pipe gallery

Abstract

The invention discloses a special buried valve well for a pipe gallery. The special buried valve well for the pipe gallery comprises a valve well body, a valve well cover plate, a pipe gallery steel pipe, a valve supporting pier, a manual valve, a blow-off valve, an emergency cut-off valve, a special performing mechanism for the emergency cut-off valve, a GPRS signal remote transmission box, a water collecting pit and a water draining system, wherein the valve well body is arranged underground; the valve well cover plate is arranged on the end surface of a wellhead of the valve well body; thepipe gallery steel pipe is arranged on the valve well body in a penetrating manner; the valve supporting pier is arranged at the bottom part of the valve well body; the manual valve and the emergencycut-off valve are arranged on the pipe gallery steel pipe and the valve supporting pier; the blow-off valve is arranged on the pipe gallery steel pipe; the special performing mechanism for the emergency cut-off valve is arranged on the emergency cut-off valve and is connected with the GRPS signal remote transmission box; the GRPS signal remote transmission box is arranged on the inner surface of the valve well cover plate; the water collecting pit is formed in the bottom part of the valve well body; and the water draining system is arranged at the outside of the valve well body and communicates with the water collecting pit. The special buried valve well for the pipe gallery is capable of performing remote monitoring and can be emergently cut off in case of fuel gas accident, and is capable of timely automatically draining water accumulated in the well.

Description

technical field [0001] The invention relates to the technical field of urban gas pipeline engineering in urban comprehensive utility corridors and other related municipal pipeline projects, in particular to a special buried valve well for utility corridors. Background technique [0002] In the construction of urban comprehensive pipe gallery, the safety requirements of urban gas pipelines are relatively high. Generally, a separate gas cabin is provided. The gas pipes entering and leaving the pipe gallery need to have functions such as emergency cut-off, remote monitoring, safety and reliability, and easy maintenance. The pipe corridor is dedicated to buried gas valve wells in order to meet the above requirements. However, at present, buried gas valve wells are all manually controlled, and there is no remote monitoring valve well with emergency cut-off. [0003] In addition, the natural gas buried valve well should be kept dry. Avoid corrosive environments as much as possibl...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the functional requirements of fireproof, explosion-proof, waterproof, and monitorable function requirements for the gas valve wells entering and exiting the pipe gallery required by the urban comprehensive pipe gallery, the technical problems to be solved by the present invention are that the existing valve wells cannot be remotely monitored, and water is easy to accumulate in the well, etc.
