Abstract
The utility model relates to a check, particularly a ball check which is suitable for the use of industrial pipelines and industrial devices. The utility model is characterized in that a filling press cover is connected with a check rod hole by threads. After the filling press cover uses the end of the press cover screwed in a thread hole to tightly press fillings, the closed degree of the fillings and a check rod is not reduced because of the frequent rotation of a handle to open and close the ball check, which realizes the purpose of no easy leakage. Compared with the prior art, the utility model has the advantages of convenient use and maintenance, long service life, reliable sealing performance, etc.
Description
The utility model relates to a kind of valve, particularly a kind of ball valve.
" the CNS compilation " the 151st the 578th page that China Standard Press published in 1993 discloses a kind of ball valve (GB12237-89) that is applicable to that industrial pipeline and equipment are used, its structure mainly is made of valve body, spheroid, seal ring, valve rod, filler, Gland, handle, wherein: push down filler at the upper end-hole place with Gland between valve rod and the valve rod hole and seal, then, the same nut with fixed handle compresses Gland.Its deficiency during use, owing to want frequent handle with sleeve to open and close ball valve, will certainly make the nut loosening of fixed handle, causes Gland not press tightly filler easily, the closed intensity of filler and valve rod is reduced, thereby cause ball valve to leak, and influences its sealing effect.
The purpose of this utility model is a kind of difficult leakage of design, the reliable ball valve of sealability.
For achieving the above object, the utility model adopts following technical solution: because existing ball valve mainly is made of valve body, spheroid, seal ring, valve rod, filler, Gland, handle.Adopt scyewed joint between Gland that now will be wherein and the valve rod hole.Like this, the Gland utilization is screwed into after gland end in the tapped hole compresses filler, and the closed intensity of filler and valve rod can not be subjected to open and close ball valve and reduce because of handle often rotates, thereby realizes that it is difficult for leaking the reliable purpose of sealability.
The utility model compared with prior art has the following advantages:
1, since between valve rod and the valve rod hole when upper end-hole is provided with sealing, at valve rod hole lower end mouth place, also be provided with the seal arrangement that constitutes by throw-out collar and pad, this has just improved the reliability of sealability greatly.
2, because this ball valve is the biswitch ball valve.When wherein a switching ball can not be used, can open another switching ball and continue to use, bring convenience to maintenance, and prolonged working life.
3, because the closed intensity of filler and valve rod can be regulated by Gland, bring convenience for regular maintenance.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the main sectional view of present embodiment.
As shown in Figure 1, present embodiment is the biswitch ball valve, it mainly is made of valve body (1), spheroid (2), seal ring (3), adjusting nut (4), valve rod (5), pad (6), filler (7), Gland (8), spring washer (9), hexagon nut (10), handle (11), wherein the sealing between valve rod (5) and the valve rod hole is taked to seal at the two-port place, one end is located at valve rod hole lower end mouth place, is made of throw-out collar (12) and pad (6); The other end is located at valve rod hole upper end-hole place, by Gland (8) by compressing the driving fit of filler (7) and valve rod (5) with being threaded of valve rod hole.
Because after Gland (8) compressed filler (7), the closed intensity of filler and valve rod was not subjected to handle often to rotate the keying ball valve and reduces, and all is provided with sealing configuration in the valve rod hole two-port, thereby realize that it is difficult for leaking, the reliable purpose of sealability.
Claims (3)
1, a kind of ball valve includes Gland (8), valve rod (5), filler (7), valve body (1), spheroid (2), seal ring (3), handle (11), it is characterized in that adopting scyewed joint between Gland (8) and the valve rod hole.
2, ball valve according to claim 1 is characterized in that the lower end mouth place between valve rod and the valve rod hole also is provided with seal arrangement, and it is made of throw-out collar (12) and pad (6).
3, ball valve according to claim 1 and 2 is characterized in that this ball valve is the biswitch ball valve.
