Problems solved by technology

[0002] According to traditional existing water dispensers, the waste water discharge pipeline is not equipped with a one-way check device, so that when the water dispenser discharges waste water, the dirty water is easy to flow back into the water dispenser, causing sanitary problems of drinking water pollution.
[0003] In addition, traditional existing water dispensers, water heaters, faucets or shower head pipelines all have a certain pressure limit. Once the predetermined safe pressure value is exceeded, if the pressure is not released, the water dispenser connected to the pipeline will be damaged. The internal structure of the water heater, faucet or shower head product itself, so if there is no automatic pressure relief device installed in the pipeline, it will cause major safety problems, and accidents of property and life loss will occur. problems and deficiencies

Abstract

The invention discloses an unidirectional water top and pressure relief device, and particularly relates to a check pressure relief valve arranged inside a body. A top cover is arranged outside the body, an arc convex surface and an arc concave surface corresponding to each other are arranged between the top cover and the check pressure relief valve, the bottom surface of the body is provided witha plurality of outflow holes, the top surface of the top cover is provided with a plurality of inflow holes, and the positions, corresponding to the plurality of inflow holes in the top cover, of theperipheral circumference of the check pressure relief valve are provided with unidirectional check portions. The check pressure relief valve is used at the waste water discharge of a water dispenserto keep dirty water from flowing back; and in addition to the unidirectional check effect, when the water flow pressure is greater than a set value, the check pressure relief valve further is characterized by having a pressure relief function.

Description

Technical field [0001] The one-way water stop and pressure relief device of the present invention is mainly applied to the technology of the one-way water stop and pressure relief device of a drinking fountain or water heater pipeline. Background technique [0002] According to the traditional existing drinking fountains, the waste water discharge pipeline is not provided with a one-way check device, so that when the drinking fountains discharge wastewater, dirty water is easily returned to the drinking fountains, which causes a sanitary problem of drinking water pollution. [0003] In addition, the traditional existing drinking fountains, water heaters, faucets or shower head pipelines have certain pressure limits. Once the predetermined safe pressure value is exceeded, if the pressure is not released, it will damage the drinking fountains and the externally connected pipelines. Water heaters, faucets, or shower heads are the internal structure of the product itself, so if there i...
