Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting wells, and in particular relates to a steel integrated fire-fighting valve well. Background Art

[0002] Traditional fire valve wells are divided into brick-built valve wells and reinforced concrete valve wells; they are usually round and square in shape; they are gate valves, butterfly valves, stop valves, ball valves, hydraulic control valves, diaphragm valves, etc. according to valve types; the connection between the pipe and the well body is usually a rigid connection. The construction of traditional brick-built valve wells is relatively complicated, the construction period is long, and they are prone to leakage; and reinforced concrete valve wells also have the problem of poor corrosion resistance. In addition, brick-built valve wells have the problem of water accumulation in the well all year round, easy to freeze in winter, and easy to be flooded in summer. The anti-seepage ability is poor, which reduces the service life of pipes and valves and poses a safety hazard. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a steel integrated fire valve well.

[0004] The purpose of the utility model is achieved in this way. The utility model is a steel integrated fire valve well, including a valve well body, a water supply pipeline running through the valve well body, a valve assembly and an opening assembly, characterized in that the valve well body is composed of a rectangular outer cylinder, an inner cylinder, a bottom plate and a cover plate made of stainless steel material, the inner cylinder is arranged in the outer cylinder, and a sandwich space is formed between the outer surface of the inner cylinder and the inner surface of the outer cylinder, and the sandwich space is filled with a thermal insulation filling layer; a manhole is provided on the top of the cover plate, and an upper cover is provided at the upper end of the manhole; a water collecting trough is provided at the lower part of the bottom plate.

[0005] Preferably, it also includes a drainage assembly, which includes a water pump and a water diversion pipe and a drainage pipe respectively connected to the water pump. The water pump is arranged on the water collection tank, one end of the water diversion pipe is connected to the water inlet of the water pump, and the other end is inserted into the water collection tank, and one end of the drainage pipe is connected to the water outlet of the water pump, and the other end is wound on the hook of the well arm of the inner cylinder.

[0006] Preferably, an escalator is arranged on the inner wall of the inner cylinder.

[0007] Preferably, the thermal insulation filling layer is polyurethane.

[0008] The utility model has the advantages that the steel integrated fire valve well of the utility model is an integral prefabricated structure, and only the foundation and the well pit need to be constructed on the construction site, which greatly shortens the construction period. At the same time, due to the steel integrated overall structure, there is no leakage problem common in on-site masonry.

[0009] In addition, the utility model provides a water collection tank and a drainage component. When water collects in the well, the upper cover is opened, the water pump is started down the well, and the water in the well is pumped out, thereby increasing the service life of the pipeline and valve components. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the utility model steel integrated fire valve well. DETAILED DESCRIPTION

[0011] The utility model is described in detail below with reference to the accompanying drawings and embodiments.
