Background
At present, the urban winter in northern China basically supplies heat in a centralized way, and the problem of uneven heat supply of each household occurs in the centralized heat supply, mainly because the heat exchange modes of each household are different, the method is mainly divided into hanging pieces and ground heating. The effect of the hanging plate type radiator is worse than that of the floor heating, the user temperature of the same water supply temperature hanging plate is low, and the temperature of the floor heating is high. If the valve is used for throttling the floor heating, the circulation problem of the floor heating part is uneven in cooling and heating; in order to ensure that the heat supply is only carried out on the premise of ensuring the hanging piece users, the room temperature of the floor heating users can be higher when the floor heating users circulate normally, the energy consumption is high, and the comfort level of the users is poor. In order to improve the comfort level of users of the floor heating, an intake and return water device for the floor heating needs to be developed.
Disclosure of Invention
In order to achieve the purpose, the utility model provides the water inlet and return device for the floor heating user. The technical scheme of the water inlet and return device for the floor heating user is as follows:
the utility model provides a warm user's water return device that advances, includes supply pipe and return water pipeline, supply water shut-off valve, venturi blender and booster pump have been set gradually along the direction of intaking on the supply pipe, be equipped with return water shut-off valve on the return water pipeline, be equipped with on the return water pipeline and be located return water shut-off valve with return water pipeline and user's return water piping connection's one end between the connecting pipe, the connecting pipe with venturi blender's injection fluid import intercommunication, venturi blender's mixed fluid export intercommunication, venturi blender's working fluid import with supply water shut-off valve intercommunication.
Further, a mixing locking valve is arranged on the connecting pipe.
Further, the water supply pipeline is provided with a water supply locking valve positioned at one side of the water supply shutoff valve far away from the Venturi mixer, and the water return pipeline is provided with a water return valve positioned at the water return shutoff valve far away from the connection
A backwater locking valve at one side of the pipe.
The utility model provides a water inlet and return device for a floor heating user, which has the beneficial effects that compared with the prior art:
the water inlet and return device for the floor heating user is arranged on the water inlet pipe and the water return pipe of the heating system for the floor heating user, the end part of the water supply pipeline is connected with the water inlet pipe, and the end part of the water return pipeline is connected with the water return pipe. The cold backwater part flowing out of the backwater pipe of the user flows into the connecting pipe and enters the Venturi mixer. The cold backwater and the hot water flowing in from the water supply pipeline are mixed in the Venturi mixer, and the mixed warm water is pressurized by the pressurizing pump and then sent to a hot user. Through installing a locking valve on the connecting pipe for adjust the volume of cold return water and adjust the temperature of warm up circulating water, can guarantee like this that hanging user's heat supply is stable qualified, also can guarantee warm up user's comfort level, the effectual energy consumption that reduces the heat supply enterprise again. Compared with the prior art, the water inlet and return device for the floor heating user is simple in structure, convenient to install and small in occupied space; the heating comfort level of the floor heating users is improved, and the energy consumption of a heat supply enterprise is reduced.
