Problems solved by technology

At present, this type of one-way valve has the problem of easy blockage. The reason is analyzed: most of the existing one-way valves are guided by the guide rod. When foreign matter in the water accumulates on the guide rod, or the surface of the guide rod is scaled after long-term use, the guide rod will be stuck. Dead, making the one-way valve function invalid

Embodiment Construction

[0028] In the description of the present invention, it should be noted that for orientation words, such as the term "center", "horizontal", "longitudinal", "length", "width", "thickness", "upper", "lower" , "Front", "Back", "Left", "Right", "Vertical", "Horizontal", "Top", "Bottom", "Inner", "Outer", "Clockwise", "Counterclockwise " and other indication orientations and positional relationships are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, or in a specific orientation. The structure and operation should not be construed as limiting the specific protection scope of the present invention.

[0029] In addition, terms such as "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying rela...

Abstract

The invention discloses an anti-blocking one-way valve. The anti-blocking one-way valve comprises a valve body which is provided with a hot water inlet, a hot water outlet, a cold water inlet and a cold water outlet; and a one-way valve cavity is formed between the hot water inlet and the cold water inlet. The anti-blocking one-way valve is characterized in that a slider capable of blocking a water inlet of the one-way valve cavity is arranged in the one-way valve cavity; the slider is provided with a plurality of guiding structures matched with the inner wall of the one-way valve cavity; andgaps are reserved between each guiding structure and the inner wall of the one-way valve cavity. When water flows through the gaps between the guiding structures and the inner wall of the one-way valve cavity, the flowing speed becomes larger, and a scouring effect is achieved, it can be prevented that water scales form an accumulation layer, and the blockage problem of the one-way valve is fundamentally solved. The invention further provides a center water heating system with the anti-blocking one-way valve.

Description

technical field [0001] The invention relates to the technical field of fluid heaters, in particular to an anti-clogging check valve and a central hot water system. Background technique [0002] When the central hot water system has no return water pipeline, in order to use the instant heating function, it is necessary to install a one-way valve at the water terminal to connect the cold and hot water pipes to form a circuit. There are many types of one-way valves for central hot water on the market, their structures are different, and their installation positions and methods are also inconsistent. At present, this type of one-way valve has the problem of easy blockage. The reason is analyzed: most of the existing one-way valves are guided by the guide rod. When foreign matter in the water accumulates on the guide rod, or the surface of the guide rod is scaled after long-term use, the guide rod will be stuck. Dead, make the one-way valve function invalid. Contents of the in...
