Abstract: A self-priming apparatus for quick no-water startup includes a front-stage inlet chamber, a middle-stage gas-liquid separation chamber, and a rear-stage gas-liquid separation chamber. A plurality of two-stage chamber gas-liquid separation one-way channels are symmetrically arranged between adjacent chambers of the front-stage inlet chamber, the middle-stage gas-liquid separation chamber and the rear-stage gas-liquid separation chamber. A plurality of one-way outlets are symmetrically arranged in an inner cavity of the rear-stage gas-liquid separation chamber. By decreasing or increasing the volumes of an outer cavity and an inner cavity of the front-stage inlet chamber, water is sucked in due to pressure difference and water intake and preliminary gas-liquid separation are carried out. The middle-stage gas-liquid separation chamber is configured for gas-liquid separation.

Abstract: A quick no-water startup apparatus for a centrifugal pump includes, from top to bottom in sequence, one-way passages (1), a self-priming chamber housing (41), sliding devices (5), a self-priming chamber (4), chamber partition plates (2) a concave-convex impeller (3), inlet channels (6) connected on two sides of the self-priming chamber (4), a spring device (7) of an upper-side x-shaped gas-liquid separation device, the upper-side x-shaped gas-liquid separation device (8), upper and middle-side gas-liquid separation device connecting shafts (9), a middle-side gas-liquid separation device (10), lower-side backflow-type gas-liquid separation devices (11), v-shaped backflow channels (122), an inverted v-shaped inlet channel (121), and an inlet.

Abstract: Clean version of the Abstract A pneumatic type water-free starting self-priming device includes a driving device, and a gas-liquid separation chamber and an expandable gas-liquid separation chamber respectively arranged on two sides of the driving device. The driving device uses high-speed gas to drive a drive disk to rotate and drive a drive shaft to rotate. The gas-liquid separation chamber uses a telescopic piston shaft rod to generate a pressure difference between the gas-liquid separation chamber and outside to suck in water, so as to realize water suction, gas-liquid separation and water drainage. The expandable gas-liquid separation chamber uses shrinkage or expansion of volumes of inner and outer chambers to generate a pressure difference to suck in water, so as to realize water suction, gas-liquid separation and water drainage. Also, the high-speed gas from the driving device flows through the two chambers, so that air can be discharged quickly.

Abstract: The present invention relates to an inbuilt seat leg support and a seat. The seat leg support is mounted in a seat. The seat includes a base frame and a cushion frame located above the base frame. A receiving space is formed between the base frame and the cushion frame. The seat leg support includes a leg support frame configured to be received in the receiving space. The leg support frame is movable and adjustable relative to the cushion frame. Movement and adjustment of the leg support frame cause the leg support frame to extend out of the receiving space to be in an extended state or to retract into the receiving space to be in a received state. According to the present invention, a receiving space for a leg support frame is reserved between a base frame and a cushion frame, and the leg support frame is disposed to be movable so that the leg support frame can be received in the receiving space when not in use. Receiving a leg support in a seat causes the present invention to be space-saving.
