Abstract
The open integral type duplex floating ball valve of the utility model, comprise valve body, valve seat, O type circle, seat ring, spheroid, lower valve rod, upper valve rod, Gland, handle, hexagon nut, valve body solid forging processes, lower valve rod loads valve body from channel interior, spheroid top fluting connects with lower valve rod, the inner threading of seat ring inserted valve seat groove screws in passage, upper valve rod lower end rectangle groove connects with lower valve rod, upper valve rod is fixed by Gland, the milling of upper valve rod top is flat is inserted in handle, handle is also tight through nut, two valve seats are provided with in valve body chamber, two spheroids, two valve seats form two sealing pairs, valve body in lumen arranges the interface of a pressure medium of releasing, outlet valve is settled in interface outer end.The utility model handle drives spheroid to rotate by valve rod, and realize opening or closing of ball valve, spheroid and internals load through passage, eliminate middle flange and bolt, have lacked the leak point at bolt place, sealability safety and reliability.
Description
Technical field
The utility model relates to ball valve, particularly relates to integral type duplex floating ball valve.
Background technique
Traditional duplex floating ball valve mostly is three-body type through Bolt Connection ball valve, and spheroid loads valve body from the side, this structure the is many leak point at bolt place.Traditional duplex floating ball valve also exists spheroid and loads valve body from the side, the problem of the leak point at many bolt places.
Model utility content
The purpose of this utility model is to provide integral type duplex floating ball valve, solves traditional duplex floating ball valve in prior art and there is spheroid and load valve body from the side, the problem of the leak point at many bolt places.
The technological scheme that the utility model adopts is: integral type duplex floating ball valve, comprise valve body, valve seat, O type circle, seat ring, spheroid, lower valve rod, upper valve rod, Gland, handle, hexagon nut, valve body solid forging processes, lower valve rod loads valve body from channel interior, spheroid top fluting connects with lower valve rod, seat ring inserted valve seat groove is inner, valve seat threading screws in valve channel, upper valve rod lower end rectangle groove connects with lower valve rod, upper valve rod is fixed by Gland, the milling of upper valve rod top is flat is inserted in handle, handle is also tight through hexagon nut, two valve seats are provided with in valve body chamber, two spheroids, two valve seats form two sealing pairs, valve body in lumen arranges the interface of a pressure medium of releasing, outlet valve is settled in interface outer end.
Lower valve rod is set to anti-blow structure.
The utility model compared with prior art tool has the following advantages: handle drives spheroid to rotate by valve rod, and realize opening or closing of ball valve, spheroid and internals load through passage, eliminate middle flange and bolt, have lacked the leak point at bolt place, sealability safety and reliability; Valve rod divides two sections, the anti-blow structure of lower valve rod, safe and reliable.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
In figure, 1. valve body; 2. valve seat; 3.O type circle; 4. seat ring; 5. spheroid; 6. lower valve rod; 7. upper valve rod; 8. Gland; 9. handle; 10. hexagon nut.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As Fig. 1, integral type duplex floating ball valve, comprise valve body 1, valve seat 2, O type circle 3, seat ring 4, spheroid 5, lower valve rod 6, upper valve rod 7, Gland 8, handle 9, hexagon nut 10, valve body 1 solid forging processes, lower valve rod 6 loads valve body 1 from channel interior, spheroid 5 top fluting connects with lower valve rod 6, seat ring 4 inserted valve seat groove is inner, valve seat threading screws in valve channel, upper valve rod 7 lower end rectangle groove connects with lower valve rod 6, upper valve rod 7 is fixed by Gland 8, upper valve rod 7 top milling is flat is inserted in handle 9, handle 9 is also tight through hexagon nut 10, two valve seats 2 are provided with in valve body 1 chamber, two spheroids 5, two valve seats 2 form two sealing pairs, valve body 1 in lumen arranges the interface of a pressure medium of releasing, outlet valve is settled in interface outer end.
Handle 9 drives spheroid 5 to rotate by valve rod, realizes opening or closing of ball valve.Spheroid 5 and internals load through passage, eliminate middle flange and bolt, sealability safety and reliability; Valve body 1 solid forging processes, and be provided with two valve seats, 2, two spheroids, 5, two valve seats 2 in valve body 1 chamber and form two sealing pairs, the valve body 1 in lumen arranges the interface of a pressure medium of releasing, and outlet valve is settled in interface outer end; Valve isolates the pressure of each entrance, and has the function of cavity between emptying valve seat 2, reaches dual fail-safe Leakage prevention, easy to operate, increases the service life.
The anti-blow structure of lower valve rod 6, safe and reliable.
The utility model handle 9 drives spheroid 5 to rotate by valve rod, and realize opening or closing of ball valve, spheroid 5 and internals load from top, achieve the inspection on pipeline and maintenance, use more convenient.
It should be noted last that, above embodiment is only unrestricted for illustration of the technical solution of the utility model, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in right of the present utility model.
