Abstract
The utility model discloses a spherical valve, which comprises a valve body (1) and a sleeve (2), wherein a spherical valve clack (3) made of a PPI plastic material is arranged in the valve body (1), a bulge (8) at the upper end of the spherical valve clack (3) is clamped with a nut rod (9); one end of the spherical valve clack (3) is connected with a sealing washer (4) that is connected with a fixed washer (5); the other end of the spherical valve clack (3) is connected with a sealing washer (6) that is connected with a screw plug (7); and the spherical valve clack (3) is further connected with the sleeve (2). Because the two ends of the spherical valve clack (3) are connected with the sealing washers, the washers can be screwed tightly when the spherical valve clack (3) and the sleeve (2) are disjointed. The utility model has the advantages of a reasonable and compact structure, as well as convenient installation and maintenance; and meanwhile, the service life of the spherical valve clack is greatly prolonged.
Description
Technical field
The utility model relates to a kind of liquid trapped line pressure valve technical field, relates to a kind of ball valve in particular.
Background technique
At present, in ball valve manufacturing and the assembly technology design unreasonable and to be not easy to maintenance also easy to wear, make valve waste water resource out of hand thereby often cause easily between sleeve pipe and the globe disk to disconnect; In addition, this flap employing metal especially iron is made, and is easy to get rusty, and working life is short.
The model utility content
For overcoming the deficiencies in the prior art, the utility model provides the technological scheme that is difficult for disconnection and globe disk long service life between a kind of sleeve pipe and the globe disk.
For achieving the above object, the utility model is realized by following technical solution:
A kind of ball valve comprises valve body 1 and sleeve pipe 2, is provided with the globe disk 3 that a PPI plastic materials is made in the described valve body 1, and there are a projection 8 and Nut pole 9 clampings in globe disk 3 upper ends.Globe disk 3 one ends are connected with a seal washer 4, and seal washer 4 is connected with retaining washer 5; Globe disk 3 the other ends are connected with seal washer 6, and seal washer 6 is connected with plug screw 7; Described globe disk 3 also is connected with sleeve pipe 2.
Compared with prior art, the beneficial effects of the utility model are: rational in infrastructure, compact; Be easy for installation and maintenance, and prolong the working life of globe disk greatly.
Description of drawings
For ease of understanding the utility model, the spy is illustrated in conjunction with the accompanying drawings.
Fig. 1 is the sectional structure schematic representation of the utility model ball valve;
Fig. 2 is the shape schematic representation of the utility model globe disk.
Embodiment
For ease of understanding the utility model, spy's specific embodiment in conjunction with the accompanying drawings is illustrated, and still, present embodiment should not regarded as any restriction of the present utility model.
In conjunction with Fig. 1, a kind of ball valve comprises valve body 1 and sleeve pipe 2, is provided with the globe disk 3 that a PPI plastic materials is made in the valve body 1, and there are a projection 8 and Nut pole 9 clampings in globe disk 3 upper ends, see Fig. 2; Because globe disk 3 upper ends have projection 8 and Nut pole 9 clampings, make its contact tightr; Globe disk 3 one ends are connected with a seal washer 4, and seal washer 4 is connected with retaining washer 5; Globe disk 3 the other ends are connected with seal washer 6, and seal washer 6 is connected with plug screw 7; Described globe disk 3 also is connected with sleeve pipe 2.Because globe disk 3 two ends all are connected with seal washer, therefore when globe disk 3 disconnects with sleeve pipe 2, can tighten packing ring; In addition, globe disk 3 adopts the PPI plastic materials to make firm wear-resisting, Never-rusty.
Claims (2)
1, a kind of ball valve comprises valve body (1) and sleeve pipe (2), it is characterized in that: be provided with the globe disk (3) that a PPI plastic materials is made in the described valve body (1), there are a projection (8) and Nut pole (9) clamping in globe disk (3) upper end.
2, ball valve according to claim 1 is characterized in that: described globe disk (3) one ends are connected with a seal washer (4), and seal washer (4) is connected with retaining washer (5); Globe disk (3) the other end is connected with seal washer (6), and seal washer (6) is connected with plug screw (7); Described globe disk (3) also is connected with sleeve pipe (2).
