Description

Technical Field

[0001] The utility model relates to a switching valve, in particular to a switching valve with a bypass pipeline. Background Art

[0002] For the water inlet switching valve at the front end or the rear end of a water tower in general buildings or individual users, since most of them are not equipped with a bypass pipeline, the raw water is directly conveyed to the water tower or the interior of individual users through the pipeline; therefore, it often causes buildings or individual users to additionally connect a complex filtered water pipeline at the front end or the rear end of the water tower to install a filtered water purification device, so as to store the raw water in the water tower after filtration to provide water for the building or directly convey the filtered water to the water pipeline in the individual user's home for use; however, there are generally problems that the original water pipeline of the building or individual user needs to be changed, and it also makes the connection of the bypass pipeline complex and difficult to confirm the pipeline for maintenance.

[0003] If a filtered water purification device is directly connected to the water inlet switching valve at the front end or the rear end of a water tower in a building or an individual user to provide filtered raw water, there is also a problem that when the filtered water purification device needs to be repaired and maintained due to a fault, the water supply must be stopped first before the repair can be carried out, which also relatively causes inconvenience in water use for the building or individual user. Content of the Utility Model

[0004] The utility model mainly utilizes the settings of a bypass water inlet and a bypass water outlet, so that users can connect a filtered water purification device, and can relatively control the water flow direction inside the pipe body of the bypass switching valve by controlling the opening or closing of the bypass water inlet valve, the raw water connection valve and the bypass water outlet valve.
