Among this technical scheme, nut welded fastening is in the water inlet one end of valve body, or rotate with the structure of coupling and connect in the valve body, be used for connecting quick-operation joint, quick-operation joint's outer joint is U type draw-in groove structure, direct joint is in the T type joint structure that corresponds such as sewage lifting mechanism, do the quick-operation joint of structure such as internal thread, convenient and sewage lifting mechanism quick connection, processing has the taper hole in the hollow stud, and the path end diameter at top is less than the diameter of floater, when playing the non return effect, the floater blocks up the top in the taper hole, the taper hole plays the effect of drawing in sewage in, make sewage act on the floater more intensively, the quick response of the floater of being convenient for.

Illustratively, referring to fig. 2, the end of the hollow stud abuts against the end of the water inlet, and a sealing ring 5 is arranged between the nut 3 and the outer joint.

In the technical scheme, the effective length of the thread of the hollow stud is greater than the length of the nut protruding out of the valve body, namely after the hollow stud and the nut are locked, the end part of the hollow stud is abutted against the end part of the water inlet, so that the sealing performance is improved, and sealing devices such as a raw material belt and the like can be arranged between the threads of the hollow stud and the nut, so that the sealing performance is improved; and after the hollow stud and the nut are locked, the nut and the outer joint extrude the sealing ring to form sealing, so that the overall sealing performance is improved.

Exemplarily, referring to fig. 1 and 4, one end of the water outlet of the valve body 1 is connected with an adaptor pipe 7 through a hoop 6, the adaptor pipe includes a first sleeve 71 sleeved on the valve body 1 and a second sleeve 72 connected to an external pipeline, the first sleeve and the second sleeve are integrally formed, and a joint of the first sleeve and the second sleeve is in smooth transition.

In the technical scheme, the first sleeve and the water outlet end of the valve body are in interference fit and locked through the hoop, and the inner diameter of the second sleeve is consistent with the outer diameter of the external pipeline and is connected through the hoop or in a heat seal or welding mode.

Illustratively, referring to fig. 2, a first annular boss protrudes from an outer wall of the water outlet, a second annular boss 711 protrudes from the first sleeve, and the first boss abuts against the second annular boss.

Among this technical scheme, valve body and first sleeve interference fit, and first boss support hold in the second boss, improve sealing performance, simultaneously, staple bolt locking back, first boss forms spacingly to the staple bolt, avoids it to switching pipe one side axial displacement, improves the fixed stability of staple bolt.

Illustratively, as shown in fig. 2, the floating ball 2 includes a gravity ball 21 disposed at the center and an elastic material 22 coated on the surface of the gravity ball.

Among this technical scheme, the gravity ball is the metal texture, guarantees that the floater has sufficient dead weight, avoids the buoyancy that sewage produced to influence its non return function, and elastic material is materials such as rubber, improves its leakproofness with the taper hole top.

To sum up, this a plastics ball valve for sewage lifting mechanism is simple and practical, and split type valve body is convenient for adopt modes such as plastics material are moulded plastics and is produced, reduction in production cost, and inside runner forms through the concatenation, is convenient for polish, forms glossy inner wall, avoids impurity to remain.
