1-2, a sewage lifting valve for a sewage lifting device includes: a valve body 10, a maintenance valve cover 20 fixed on the valve body 10, and a rotary valve disc 40 rotatably connected to the valve body 10. , a surface of the valve body 10 is provided with an inspection port, the inspection valve cover 20 is clamped on the inspection port, and a rotating frame 30 is fixed on the inner wall of one side of the inspection port. A rotating hole is provided, and a rotating valve flap 40 is inserted into the rotating hole. The valve body 10 includes a water inlet section 12, an elbow section 11 integrally communicated with the water inlet section 12, and the elbow section. Section 11 is an integrally connected water outlet section 13, the rotary valve flap 40 is located at the position of the water inlet section 12 and is in conflict with the inner wall of the water inlet section 12, the protruding surface of the rotary valve flap 40 is close to the water inlet section 12, the rotary valve The concave surface of the flap 40 is close to the water outlet section 13, and the elbow section 11 is provided with an arc-shaped groove near the water inlet section 12. The arc-shaped groove and one end of the rotary valve flap 40 form an impurity accommodating cavity 43. When the water inlet section 12 enters the water, the rotary valve flap 40 rotates away from the water inlet section 12 by the power of the water flow, so that the water flow normally flows into the water inlet section 12. In the water outlet section 13, when there is sewage backflow at the water outlet section 13, the rotary valve disc 40 rotates toward the water inlet section 12 under the power of the backflow sewage, thereby closing the port of the water inlet section 12, so that the sewage cannot be Reverse flow, and the impurities in the sewage in the water inlet section 12 and the sewage in the water outlet section 13 are deposited in the impurity accommodating cavity 43 when flowing, so that the rotary valve flap 40 works normally and will not get stuck.

Further, the water outlet section 13 is placed in the horizontal direction and parallel to the horizontal plane, the water inlet section 12 is placed in the vertical direction and perpendicular to the horizontal plane, and the sewage lift valve is installed on the sewage lifter during installation. , to facilitate the maintenance of the poppet valve and reduce the volume of the lifter. At this time, the lifter does not need to install up and down ladders.

Further, a connecting port section 14 is communicated with the water outlet section 13, a valve cover 15 is fixed on the connecting port section 14, a valve stem 50 is arranged in the connecting port section 14, and the valve One end of the rod 50 is fixed with the runner handle 60, and the other end is provided with a tooth and is threadedly connected with a blocking rod 70. The blocking rod 70 extends from the connecting port section 14 to the water outlet section 13. During maintenance, turn the wheel handle 60 at this time, and drive the valve stem 50 to rotate, so that the blocking rod 70 moves toward the inner wall of the water outlet section 13, thereby blocking the water outlet section 13, completely blocking the backflow of sewage, and then open for maintenance Bonnet 20, for servicing the poppet valve.

Further, the rotary valve flap 40 includes a valve flap ball 41, one end of the valve flap ball 41 is an arc-shaped end 42, the other end is an abutting plane end 47, and one side of the valve flap ball 41 is an irregular concave surface 45. , the opposite side of the valve flap ball 41 and the irregular concave surface 45 is a spherical surface 46, the flat end 47 of the valve flap ball 41 is in conflict with the inner wall of the valve body 10, and the bottom end of the arc-shaped end 42 is in contact with the valve body 10. The inner wall of the valve body collides to form a contact surface 48, and the flat end 47 and the arc-shaped end 42 both conflict with the inner wall of the valve body 10 to make the water inlet form a closed area to prevent the water from flowing backwards, and the valve disc ball 41 is far away from the arc-shaped A rotating handle 49 is integrally connected to one end of the end 42 , and a rotating shaft 410 is integrally connected to the rotating handle 49 , and the rotating shaft 410 is inserted into the rotating frame 30 .

Working principle: When the water inlet section 12 enters the water, the rotary valve disc 40 rotates away from the water inlet section 12 by the power of the water flow, so that the water flow normally flows into the water outlet section 13. When there is sewage backflow at the water outlet section 13, At this time, the rotary valve flap 40 rotates toward the water inlet section 12 under the power of the backflowing sewage, thereby closing the port of the water inlet section 12, so that the sewage cannot flow back, and the sewage in the water inlet section 12 and the water outlet section 13 are separated. The impurities in the sewage are all deposited in the impurity accommodating chamber 43 when flowing, so that the rotary valve disc 40 can work normally and will not be stuck. When the poppet valve needs to be repaired, turn the wheel handle 60. By driving the valve stem 50 to rotate, the blocking rod 70 moves toward the inner wall of the water outlet section 13, thereby blocking the water outlet section 13, completely blocking the backflow of sewage, and then opening the maintenance valve cover 20 to repair the poppet valve. .
