Description of drawings
The pneumatic lining fluorine of a kind of fast opening and closing ball valve schematic representation that Fig. 1 provides for the utility model;
Fig. 2 is valve rod and a spheroid integral structure schematic representation in the utility model.
Embodiment
For the utility model is become apparent, now with a preferred embodiment, and conjunction with figs. is described in detail below.
As shown in Figure 1, the pneumatic lining fluorine of a kind of fast opening and closing ball valve that provides for the utility model, comprise pneumatic actuator, pneumatic actuator links to each other with the valve stem part of valve rod and spheroid integral structure 13, spheroid both sides partly at valve rod and spheroid integral structure 13 are respectively equipped with a left valve barrel 16 and right valve barrel 1, between left valve barrel 16 and right valve barrel 1 and valve rod and spheroid integral structure 13, be provided with seal ring 15, at left valve barrel 16, have the passage of allowing the medium circulation in the spheroid part of right valve barrel 1 and valve rod and spheroid integral structure 13, on passage, be provided with one deck lining fluorine layer 17.
Pneumatic actuator comprises pneumatic actuator 7, is provided with solenoid valve 8 on pneumatic actuator 7, is provided with electropneumatic valve positioner 9 on the output shaft 12 of pneumatic actuator 7, is provided with limitation travel switch 10 and source of the gas and handles three linked piece 11 on electropneumatic valve positioner 9.Outside the end of the valve stem part of valve rod and spheroid integral structure 13, be with Stuffing box 3, between the end of the valve stem part of Stuffing box 3 and valve rod and spheroid integral structure 13, be provided with filler 2, above filler 2, be pressed with Gland 4, one end of Gland 4 is enclosed within outside the end of valve stem part of valve rod and spheroid integral structure 13, the other end links to each other with connecting sleeve 6, connecting sleeve 6 links to each other with described pneumatic actuator 7, connects support 5 Stuffing box 3 is linked to each other with described pneumatic actuator 7.
In conjunction with Fig. 2, the left and right sides face of valve rod and spheroid integral structure 13 spheroids part reaches up and down, and both ends of the surface are respectively the plane, be arc transition between upper and lower end face and the left and right side, seal ring 15 contact with valve rod and spheroid integral structure 13 part shape and the shape of valve rod and spheroid integral structure 13 adapt.
For existing ball valve, its spheroid and valve rod separate, and open the bar arc groove on the spheroid, the flat tenon of valve rod one end mill, and flat tenon one end of valve rod inserts in the spheroid arc groove and gets final product during installation.In the utility model, spheroid and valve rod fuse, and its purpose mainly is to become flexible for fear of producing the gap between valve rod and the spheroid, and rotation valve rod is exactly a rotating sphere behind the employing linking body structure, and rigidity is strong, transmits torsion and can not lose.
According to practical experience, if spheroid and seal ring surface of contact are big more, open and close just heavy more, if the few more keying of spheroid and seal ring surface of contact is just light more, so, the utility model changes over as shown in Figure 2 geometrical shape to spheroid, and the shape of seal ring is also done adaptive change, and it is brisk that valve opening and closing is just felt.
Fluoroplastic are new materials of development in recent years, have superior corrosion resistance, almost can resist all chemical mediators, comprise the corrosion of agricultural nitric acid and chloroazotic acid.And it can also use for a long time 180 ℃ of following temperature, also has self lubricity, electrical insulating property, and creep resistance and non-viscosity can both satisfy the requirement of special operation condition.Therefore, in the utility model, adopted lining fluorine layer 17.
Further, because pneumatic actuator does not have spark to occur, so the pneumatic lining fluorine of a kind of fast opening and closing ball valve that the utility model provides can be applied in the petrochemical equipment.Pneumatic actuator 7 of the present utility model is to adopt pneumatic double-piston final controlling element.Limitation travel switch 10 is contained in pneumatic actuator 7 tops, and its effect is that transmission pneumatic actuator 7 and valve location signal arrive on-the-spot and remotely-controlled operation station, electropneumatic valve positioner 9 and pneumatic actuator 7 supporting uses.The dc current signal of input 4～20Ma ADC just is convertible into output pressure power, and the action of control executing mechanism is fed back according to actuator simultaneously, and the position of valve can correctly be located by the control signal air inlet of regulator output.
