Description

Fire pump adapter

technical field

The utility model relates to the technical field of fire protection, in particular to a fire-fighting water pump adapter.

Background technique

The fire pump adapter is a self-contained fire-fighting facility for high-rise buildings. It is used to connect fire trucks and motor pumps to deliver fire-fighting water to the building pipe network. The fire truck sends water to the fire water supply system inside the building and pressurizes it through the interface of the adapter, so that the indoor fire hydrants or other fire extinguishing devices of the water supply system inside the building can get sufficient pressure water to extinguish fires on different floors, thus solving the problem of high-rise buildings. After a fire breaks out in a building (or other various buildings), it is difficult for fire trucks to extinguish the fire, or due to the low water pressure of the indoor fire water supply pipe inside the building, the water supply is insufficient or cannot be supplied.

However, the water inlet interface of the existing fire pump adapter is parallel to the fixed flange and cannot be installed underground. If it is installed underground, it will not be able to connect and operate or the operation will be significantly limited by space. It is extremely inconvenient to use in freezing areas with large temperature difference between day and night.

Utility model content

Aiming at the deficiencies of the existing technology, the technical problem to be solved by the utility model is to provide a fire-fighting water pump adapter, which is suitable for being installed underground and is easy to connect and operate.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

The fire water pump adapter includes an adapter housing, the bottom of the adapter housing is provided with a horizontal fixing flange, and the top of the adapter housing is provided with a water inlet interface for connecting with the fire water pump. The axis of the interface is perpendicular to the flange face of the fixed flange.

Further, the adapter housing is provided with a valve, and the side of the adapter housing is provided with a valve handwheel.

The top of the adapter housing is connected with a vertical water inlet pipe, and the water inlet interface is arranged at the end of the water inlet pipe.

The water inlet pipe is two water inlet branch pipes arranged side by side.

The water inlet port is provided with a sealing cover.

The sealing cover is connected with the adapter housing through a chain.

Compared with the prior art, the utility model has the following advantages:

The structure design of the fire pump adapter is reasonable, the water inlet interface is set vertically with the lower fixed flange, that is, the water inlet interface is set upwards, and the adapter can be installed underground to prevent cold and frost. People can use a fire wrench on the ground. The opening and closing interface is easy to connect and operate.

detailed description

The specific implementation of the present utility model will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

As shown in FIG. 1 , the fire pump adapter includes an adapter housing 1 , and the bottom of the adapter housing 1 is provided with a horizontal fixing flange 2 , through which the fixing flange 2 is connected to the building fire protection pipeline.

The adapter housing 1 is vertically arranged, and the top of the adapter housing 1 is provided with a water inlet port 5 for connecting with the fire pump. The axis of the water inlet port 5 is perpendicular to the flange surface of the fixed flange 2, that is, the water inlet port set vertically.

The water inlet interface 5 is vertically arranged to be convenient to connect and operate with the fire pump. This type of adapter is suitable for being installed in the well to prevent cold and freeze. People can open and close the interface with a fire wrench on the ground, and the connection operation is easy.

The adapter housing 1 is provided with a valve, and the side of the adapter housing is provided with a valve hand wheel 3 . The top of the adapter housing is connected with a vertically arranged water inlet pipe, the water inlet interface is arranged at the end of the water inlet pipe, and the water inlet interface is provided with a sealing cover 6 .

The water inlet pipe is two water inlet branch pipes 4 arranged side by side, forming two water inlet interfaces arranged side by side, which can improve water inlet efficiency and water pressure.

The sealing cover 6 is connected with the adapter housing by a chain, and the sealing cover is not easy to lose. The adapter is installed underground without occupying external space, and is anti-freezing, suitable for use in freezing regions with large temperature differences between day and night.

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned method, as long as various insubstantial improvements made by the idea and technical solutions of the utility model are adopted, or there is no The design and technical solutions of the utility model that are directly applied to other occasions through improvement are all within the protection scope of the utility model.
