Abstract
The utility model discloses a lining fluorine ball valve, aiming to provide a lining fluorine ball valve sealing structure with better sealability and simpleness and convenience in installation. The technical key is as follows: the lining fluorine ball valve comprises a valve body, a valve rod, a ball body and a gland, wherein the gland is arranged at the upper of the valve body and is connected with the valve body, the ball body is arranged in the valve body, the valve rod passes through the gland to be connected with the ball body in the valve body, a sealing ring is arranged between the valve rod and the valve body in a clinging way, the sealing ring is arranged under the gland in a clinging way, and one side of the sealing ring, contacted with the valve rod, and one side of the sealing ring, contacted with the valve body, are respectively provided with a fluorine-containing O-shaped sealing ring.
Description
Technical field
The utility model relates to a kind of technical field of ball valve, and more particularly, it relates to a kind of lining fluorine ball valve.
Background technique
Lining fluorine ball valve is to make open-shut device with the spheroid of band manhole, and spheroid rotates to realize valve opening and to close around the valve body center line with valve rod.Adopt special mould pressing process, make sealing surface fine and close good, V-type PTFE filler combination makes valve reach zero leakage in addition; Spheroid and valve rod are cast as one, and have stopped to go out the possibility in the pressure part because variation in pressure causes valve rod the Security during basic assurance is used; Adopt all-plastic lining technology, the deep-etching of media-resistant.
Traditional lining fluorine ball valve comprises valve body 1, Gland 3, stuffing box 5, last filler 51, middle filler 52, following filler 53, valve rod 2, spheroid; Gland 3 is connected through hex head bolt 4 with stuffing box 5; Last filler 51, middle filler 52, filler 53 is arranged at stuffing box 5 inside down; Valve rod 2 is connected with spheroid, and spheroid is installed in the valve body 1 through valve rod 2.
The component that the last sealing configuration of this traditional lining fluorine ball valve need be installed are more, and processing is difficult, and also waste material makes cost higher, owing to be packing seal, so inconvenient operation, being unfavorable for switch when tight, Song Shiyi reveals, and is unfavorable for maintaining.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide a kind of lining fluorine ball valve sealing structure of simple in structure, easy processing.
For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of lining fluorine ball valve, comprise valve body, valve rod, spheroid and gland, and gland places the valve body top and is connected with valve body; Said spheroid is arranged in the valve body; Said valve rod passes gland and is connected with the interior spheroid of valve body, be close between said valve rod and the valve body to be provided with seal ring, and seal ring is closely set in the gland below.
Through adopting technique scheme, packing seal is become through seal ring seal, reduced stuffing box and filler, reduced assembling set, processing is easier to, and has practiced thrift material and has reduced procedure, has reduced cost.
The utility model further is set to: said seal ring is equipped with bag fluorine O-ring seals with the side that valve rod, seal ring contact with valve body.
Through the employing technique scheme, further enhanced leaktightness performance, owing to be bag fluorine O-ring seals, more corrosion-resistant than general seal ring, life time is more permanent.
Description of drawings
Fig. 1 is the utility model lining fluorine ball valve embodiment's structural representation;
Fig. 2 is the A portion enlarged view of Fig. 1;
Fig. 3 is the prior art constructions schematic representation;
Fig. 4 is the B portion enlarged view of Fig. 3.
Embodiment
Referring to figs. 1 through Fig. 4 the utility model lining fluorine ball valve embodiment is further specified.
A kind of lining fluorine ball valve; Comprise valve body 1, valve rod 2, spheroid 3 and gland 4, gland 4 places valve body 1 top and is connected with valve body 1, and said spheroid 3 is arranged in the valve body 1; Said valve rod 2 passes gland 4 and is connected with valve body 1 interior spheroid 3; It is characterized in that: be close between said valve rod 2 and the valve body 1 and be provided with seal ring 5, and seal ring 5 is closely set in gland 4 belows, said seal ring 5 is equipped with bag fluorine O-ring seals 51 with the side that valve rod 2, seal ring 5 contact with valve body 1.
When liquid got into valve body 1 by inlet, seal ring 5 constituted double seal with bag fluorine O-ring seals 51, makes the sealability of ball valve be guaranteed; And bag fluorine O-ring seals 51 is more corrosion-resistant than general seal ring, so working life is also just more permanent, whole sealing configuration has reduced component such as stuffing box and filler; Reduce material, practiced thrift economy, also reduced the step of installing simultaneously; Structure is more simple and convenient, easy processing.
Claims (2)
1. one kind serves as a contrast the fluorine ball valve; Comprise valve body, valve rod, spheroid and gland; Gland places the valve body top and is connected with valve body, and said spheroid is arranged in the valve body, and said valve rod passes gland and is connected with the interior spheroid of valve body; It is characterized in that: be close between said valve rod and the valve body and be provided with seal ring, and seal ring is closely set in the gland below.
2. lining fluorine ball valve according to claim 1 is characterized in that: said seal ring is equipped with bag fluorine O-ring seals with the side that valve rod, seal ring contact with valve body.
