[0002] The applicant applied for the name on December 21, 2009: a water cut-off protector, patent number: ZL 200920244397.3, the patent is that the tap water passes through the sealing water port and directly enters the lower water chamber. When the water intake is large, the float will be washed by the water When it is down, the blockage will be closed. It can only be used when the flow rate is small and the flow rate is slow. It is not suitable for use when the flow is large.

Abstract

The invention relates to an automatic water cutting protector. The automatic water cutting protector comprises a cylindrical valve body, an upper valve cover, a lower valve cover, a plugging, a connecting rod, a buoy unit and a rest button unit, wherein the top of the cylindrical valve body is in threaded connection with the upper valve cover; the bottom of the cylindrical valve body is in threaded connection with the lower valve cover; the cylindrical valve body is internally provided with a partition plate, and the partition plate is used for dividing the interior of the cylindrical valve body into an upper water cavity and a lower water cavity; the upper end of the exterior of the cylindrical valve body is provided with a water inlet, the water inlet is communicated with the upper water cavity, and the lower end of the exterior of the cylindrical valve body is provided with a water outlet; and the water outlet is communicated with the lower water cavity, and the buoy unit is arranged in the lower water cavity. The automatic water cutting protector provided by the invention has the advantages that the cost is cheap, the use is convenient, the structure is compact, the property is reliable, and the service life is long.

Description

technical field [0001] The invention relates to a valve body, in particular to a water cut-off protector. Background technique [0002] The applicant applied for the name on December 21, 2009: a water cut-off protector, patent number: ZL 200920244397.3, the patent is that the tap water passes through the sealing water port and directly enters the lower water chamber. When the water intake is large, the float will be washed by the water When it is down, the blockage will be closed, and it can only be used when the flow rate is small and the flow rate is slow, and it is not suitable for use when the flow is large. Contents of the invention [0003] Based on the above situation, the present invention discloses a water cut-off protector after improvement. The larger the flow of tap water flowing into the device, the better the buoyancy of the buoy, and the plugging will naturally maintain the normally open state. [0004] The technology adopted in the present invention is as ...
