Example 1

Referring to fig. 1-5, a convenient one-way drain valve comprises a valve body 1, wherein the inner surface of the valve body 1 is a smooth surface, the outer side of the bottom of the valve body 1 is provided with an inclined surface 4, the inclination of the inclined surface 4 is 8-10 degrees, the valve body 1 is convenient to install, the top end of the valve body 1 is fixedly connected with a plurality of bosses 2, the bosses 2 and the valve body 1 are integrally formed, the plurality of bosses 2 are equidistantly distributed at the top end of the valve body 1, a water inlet 3 is arranged between every two adjacent bosses 2, a water inlet cavity 6, a buffer cavity 7 and a water outlet cavity 8 are sequentially arranged in the valve body 1 from top to bottom, a floating ball 9 is arranged in the buffer cavity 7, the density of the floating ball 9 is less than that of water, a plurality of clamping seats 5 are fixedly arranged on the outer wall of the valve body 1, the plurality of clamping seats 5 are arranged around the outer wall of the valve body 1, and the inclination angle is 3-5 degrees to prevent the one-way drain valve from loosening and falling off after being installed.

As the utility model discloses an optimal technical scheme, cushion chamber 7 is equipped with waist mouth and lower waist mouth respectively with intake antrum 6, the junction of play water cavity 8, the diameter of going up waist mouth and lower waist mouth all is less than the diameter of floater 9, can guarantee the floater like this, and more times are in the intermediate position of cushion chamber 7 when the drainage, and the drainage is smooth in the same direction as.

Example 2

Referring to fig. 1 to 5, the other contents of the present embodiment are the same as embodiment 1, except that: the water inlet cavity 6, the buffer cavity 7 and the water outlet cavity 8 are all arc-shaped, and the joints of the buffer cavity 7, the water inlet cavity 6 and the water outlet cavity 8 are in arc-shaped transition, so that the drainage is smooth and the sealing performance is high.
