Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
As shown in fig. 1, the utility model provides a pair of automatic switch-over water supply installation, including main pipeline 1 and branch pipeline 2, main pipeline 1 forms T style of calligraphy structure with branch pipeline 2 through connection, main pipeline 1's one end is provided with the pipe wall that passes branch pipeline 2 and with the main pipeline water inlet 12 of branch pipeline 2 intercommunication, main pipeline 1's the other end is provided with main pipeline delivery port 13, the one end of branch pipeline 2 is provided with first check valve 3 and first water inlet 10, the other end of branch pipeline 2 is provided with first water suction pipe head 4, second check valve 5 and second water inlet 11, first water suction pipe head 4 sets up in second water inlet 11.
Further, automatic switching water supply installation still includes fire pump 8, the one end that main 1 was provided with house steward delivery port 13 communicates with fire pump 8.
The automatic switching water supply device is directly integrated into a water suction pipeline of the fire engine. The branch pipeline 2 is provided with one end of a first check valve 3 and is fixedly communicated with a water tank 7 of the fire engine, and one end of the branch pipeline 2, which is provided with a second check valve 5, is connected with an external water supply device through a first water suction pipe joint 4. The utility model can realize automatic switching of the water supply pipeline and effectively prevent liquid from flowing backwards, and the utility model adopts automatic operation without real-time monitoring of water consumption by a machine operator; the water supply of the water tank 7 of the fire engine is not required to be interrupted when the external water supply is established, and the continuous water supply can be ensured.
Further, the water outlet of the fire pump is provided with a second water suction pipe joint 9, and the second water suction pipe joint 9 is used for communicating with an external fire-fighting water spraying pipe.
Further, the first check valve 3 is a swing check valve. All opening and closing pieces of the swing check valve are arranged in the valve body, do not penetrate through the valve body, avoid the possibility of leakage of the valve and are suitable for cleaning media.
Further, the second check valve 5 is a spring type check valve. The spring type check valve has short valve clack stroke and light valve clack, is closed by the aid of the spring, is high in valve closing speed, and can effectively prevent liquid in the branch pipeline 2 from flowing back to flow out of the second water inlet.
