Abstract
The present invention relates to a flush valve that is capable of smoothly draining the washing water by using a vacuum prevention mechanism of a simple structure.
The present invention provides a valve housing (1), a flush valve body (7) installed in the valve housing (1) to open and close the flow path and extend the opening and closing rod (8) to one side, the operation member (12), the valve housing ( The cap member 20 screwed to the operating member connecting portion 4 of 1), the cylindrical push guide 22 coupled to the inside of the operating member connecting portion 12, and the flush through the push guide 22. In the flash valve including the operation rod 24 extending toward the opening and closing rod 8 of the valve body 7 and the spring 15 for elastically supporting the operation rod 24, the push guide 22 An air hole 32 is formed on a surface of the valve housing 1 toward the inner side of the valve housing 1, and the U-packing member 34 is coupled to the push guide 22 adjacent to the air hole 32, and the operation member connecting portion ( 4) or an air hole through which air is constantly introduced into a gap between the periphery of the cap member 20 or the periphery of the central hole 28 of the cap member 20 and the operation member 12. Or 36) is formed.
Description
The present invention relates to a flush valve having a vacuum prevention mechanism, and more particularly, to a flush valve having a vacuum prevention mechanism having a new structure that allows the washing water to be discharged smoothly using a vacuum prevention mechanism having a simple structure. will be.
The toilet or urinal of the toilet is provided with a flush valve or a flushing valve for flushing down the toilet after the user views the toilet. The flush valve is discharged quickly as soon as the valve is opened, it is necessary to wash the feces or urine by the rapid flow of the discharge water. In order to ensure a rapid discharge of the wash water as described above, such a flush valve is provided with a vacuum preventing device for preventing a vacuum or negative pressure from being formed therein. If a vacuum or negative pressure is formed inside the valve, the washing water may not be discharged smoothly and quickly, so that the feces or urine cannot be sufficiently washed out, and the sewage may flow back.
However, such a conventional flush valve has a vacuum prevention mechanism including a separate body including an air inlet and a packing member at a connection portion of the valve body and the discharge pipe so that vacuum or negative pressure is not formed in the valve body. However, such a conventional flush valve is not only bulky and takes much material, but also occupies a lot of installation space, and thus has a problem of high cost and inefficiency.
The present invention has been proposed in view of the problem of the flush valve related to the conventional vacuum prevention mechanism as described above, the present invention is simple in structure and does not occupy a separate space, it is small in volume, can save material In order to provide a flush valve with a vacuum prevention mechanism of a new structure, it is effectively installed even in a narrow installation space.
According to one feature of the invention, the washing water inlet (2) is formed protruding on one side and the washing water discharge port (3) and the operation member connecting portion (4) formed on the other side, respectively, the pressure chamber (5) is formed on one side A flush valve body (7) installed in the housing (1), the valve housing (1) to open and close the flow path, and the opening / closing rod (8) extends to one side, and the operation member connecting portion (4) of the valve housing (1).
