Pipe upper sleeve rubber sleeve, rubber sleeve grafting is fixed on the inwall of liquid outlet, and the rubber sleeve of conduit surrounding forms some leading to
Hole, forms the slotted eye of connecting tube endoporus on the duct wall on the downside of rubber sleeve.
Form concave station on the side wall of the drain pipe, feed tube is resisted against on the bottom surface of concave station, feed tube it is relative two
Draw-in groove is formed on the wall of side.
The top grafting of the drain pipe is fixed with end cap, and end cap is resisted against back on liquid cylinder, and tracheae is formed on end cap
Via.
The aperture of the liquid outlet bottom end outlet is equal to the diameter of conduit outer ring.
The center of the rubber sleeve forms centre bore, and conduit is plugged in the centre bore of rubber sleeve, rubber sleeve centre bore
Aperture less than conduit outer ring diameter.
Described through hole is in circular arc, and through hole is uniformly distributed in a ring around rubber sleeve center.
Sealing ring is fixed with the inwall of the liquid outlet bottom end outlet, conduit is plugged in sealing ring.
The beneficial effects of the present invention are：
1st, its simple structure, it can realize the closing to the liquid-feeding tube mouth of pipe, realize double-deck guarantor while resorption liquid
Shield, can be prevented effectively from the liquid drippage of the drain pipe mouth of pipe.
2nd, the structure that it is used simultaneously can be to feed liquor duct occlusion in disconnected liquid, influence of the feed tube to drain pipe during disconnected liquid
It is small.
