Description
Technical field
The present invention relates to hard seal ball valve technical field, more particularly to a kind of forged steel metal hard-sealing ball valve.
Background technique
Hard seal ball valve is suitable for high temperature, high pressure and contains the media such as solid particulate matter, slurry, fiber, polymer
Repid cut-off valve, valve seat and the centre of sphere by forged steel handle, can be widely applied to petrochemical industry, high pressure coal gasification, plastic polymer,
The industries such as vapour system, mining industry, metallurgy, chemical fibre, and when the work of fixed metal hard-sealing ball valve, Fluid pressure is in sphere before valve
The active force of upper generation all passes to bearing, and it is mobile to valve seat will not to make sphere, thus valve seat is not subject to excessive pressure,
So Fixed ball valve is suitable for high pressure, heavy caliber occasion.
But the spring in existing fixed metal hard-sealing ball valve at work due to fracture and it is biggish forever
Deformation long or loss bearing capacity, are easy to cause failure, and spring determines the stroke of cracking pressure, flap in valve in valve
And the stability sealed in the off state, it may be said that spring failure is the pass for influencing metal hard-sealing ball valve normal use
One of key problem, and because spring is located at the inside of metal hard-sealing ball valve, even if spring fails, also it is not easy to carry out more

Circle and spring body；
Wherein, the sphere is installed, the valve rod is forged to through the valve body with the sphere in the cavity of the valve body
One, the driving device drive the sphere rotation by the valve rod；The auxiliary valve body is located at the two sides of the valve body, institute
Auxiliary valve body is stated to be detachably connected with the valve body；The valve seat is installed in the cavity of the auxiliary valve body, the valve seat with it is described
Sphere connection composition sealing pair, between the sealing pair and the auxiliary valve body inner wall be equipped with the pressing ring, the valve seat with it is described
Sealing ring is installed between pressing ring；The spring body is installed, the auxiliary valve body corresponds to the spring position in the pressing ring
It sets and offers spring body mounting hole.
Further, the spring body includes spring and pedestal, and the spring is fixed on the base.
Further, the pedestal is threadedly coupled with the spring body mounting hole.
Further, the top of the valve body is fixed with stuffing box, the stuffing box and the valve body by straight pin into
Row positioning.
Further, graphite packing, the graphite packing and the valve rod are filled in the stuffing box or the valve body
Collectively constitute sealing pair.
Further, hold-down grid is additionally provided between the stuffing box and the valve rod, described in the hold-down grid compresses
Graphite packing.
Further, the valve body and the auxiliary valve body, the stuffing box junction are equipped with metal and wind graphite pads.
Further, the detachable connection method of the valve body and the auxiliary valve body is to be bolted.
By taking above scheme, the beneficial effects of the present invention are:
1) by opening up spring body mounting hole on auxiliary valve body, in spring breaking down failure, spring body can be dismantled out of pressing ring
Out, it and then is replaced, new spring body is screwed into spring body mounting hole, is eventually arrived in pressing ring；
2) valve rod is structure as a whole with sphere forging, and sphere will not influence sealing effect because generating offset in valve body, passes through
The structure that forging method is produced, fluid resistance is small, durable, significantly lengthening service life；
3) by stuffing box and graphite packing, medium can be prevented to leak from valve rod；
4) valve body and auxiliary valve body, valve body can be sealed with stuffing box junction by winding graphite pads by metal, prevent from being situated between
Matter leakage；
5) be bolted by valve body and auxiliary valve body, realize and be detachably connected, convenient for inside auxiliary valve body valve seat, pressing ring,
Sealing ring is repaired or replaced.
It can be seen via above technical scheme that compared with prior art, the present disclosure provides a kind of forged steel metallic hards
Seal ball-valve solves the problems, such as that spring failure is non-exchange in existing metal hard-sealing ball valve, and sealing performance of the present invention
It is excellent, it is durable, increase service life.
