Description
Technical field
The utility model relates to a kind of double-seal ball valve, especially a kind of double-seal ball valve structure with pressure relief device.
Background technique
The middle cavity pressure of double-seal ball valve can not be discharged in currently available technology, long-term to overstock the usability that will affect valve
Energy and safety.
Utility model content
To overcome above-mentioned prior art problem, the utility model provides a kind of double-seal ball valve knot with pressure relief device
Structure.
The technical solution of the utility model is a kind of double-seal ball valve structure with pressure relief device, including valve seat support ring,
The valve seat support ring back is equipped with packing seal circle, and the packing seal circle is compressed by pressing ring and spring, the valve seat
Bracing ring is equipped with sealing ring I and sealing ring II, and the sealing ring I and sealing ring II are abutted with sphere, the valve seat support ring
It is equipped with spring I between sealing ring II, steel ball is equipped between the sealing ring II and spring I, the valve seat support ring is equipped with through-hole I,
The sealing ring II is equipped with through-hole II, and the through-hole I is communicated with through-hole II, and the through-hole II is communicated with lumen.
Further, the steel ball size is greater than II aperture of through-hole, and I outer diameter of spring is greater than II aperture of through-hole.
The utility model has the beneficial effects that middle cavity pressure can be released in channel by through-hole, guarantee making for valve
With performance and safety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1. valve seat support rings；2. packing seal circle；3. pressing ring；4. spring；5. sealing ring I；6. sealing ring
Ⅱ；7. spring I；8. steel ball；9. through-hole I；10. through-hole II；11. lumen；12. sphere.
Specific embodiment
As shown in Figure 1, a kind of double-seal ball valve structure with pressure relief device, including valve seat support ring, the valve seat support
It encloses back and is equipped with packing seal circle, the packing seal circle is compressed by pressing ring and spring, and the valve seat support ring is equipped with
Sealing ring I and sealing ring II, the sealing ring I and sealing ring II are abutted with sphere, between the valve seat support ring and sealing ring II
Equipped with spring I, steel ball is equipped between the sealing ring II and spring I, the valve seat support ring is equipped with through-hole I, the sealing ring II
Equipped with through-hole II, the through-hole I is communicated with through-hole II, and the through-hole II is communicated with lumen, and the steel ball size is greater than through-hole II
Aperture, I outer diameter of spring are greater than II aperture of through-hole.
When valve working, pressure medium is acted on by through-hole I in valve seat support ring and pushes sealing ring I and ball on steel ball
Body, which is in close contact, realizes sealing, when valve lumen hypertonia in cavity pressure steel ball acted on by through-hole II on sealing ring II
Upper promotion steel ball is released to middle cavity pressure in channel by through-hole I in valve seat support ring.
